Terrasmart trackers now with hail stow feature Terrasmart reports that the hail mitigation system uses cloud-based monitoring to automatically trigger optimum stow position to protect solar assets without requiring operator intervention.

Report shows U.S. states and utilities easing into EVs The number and scope of electric vehicle regulations and charging incentives are increasing.

Utilities plan hydrogen power projects that crowd out renewables Several utilities have proposed hydrogen-capable generating units in their resource plans, a research center reports. But hydrogen projects face hurdles such that they “may not work” and conflict with renewables, another research group says.

The impact of semi-transparent solar modules on agrivoltaics yield Researchers have conducted a field study across two growing seasons, growing different kinds of vegetables under three types of modules with 40%, 5%, and 0% transparency. Their work is the first replicated research experiment that evaluates module transparency in an irrigated vegetable field setting.

New research finds solar module anti-reflective coatings may reduce LCOE by over 2% Researchers in Morocco have examined the effects of an anti-reflective coating on solar panel performance under desert conditions and have found that it enhanced both the annual performance ratio and the energy yield by 2% and 5.5%, respectively. They have also found it to be durable and able to withstand dry cleaning methods under accelerated testing.

Canadian Solar drops 15% post Q2 earnings report The solar company logged $1.64 billion in revenue, down from $2.36 billion in the previous year’s Q2.

Canadian Solar (Nasdaq: CSIQ), a global provider of solar modules, energy storage, and other clean energy components and solutions, announced its Q2 2024 earnings

The company posted $1.64 billion in revenues, roughly coming in line with Wall Street expectations. However, revenues are down from $2.36 billion in Q2 2023, and the company’s share price declin.ed about 15% in the trading session following the earnings report.

Canadian Solar attributed the decline in revenues to sharply falling global solar module prices.

Total module shipments recognized as revenues in the second quarter of 2024 were 8.2 GW, up 30% quarter-over-quarter and remained consistent year-over-year. Of the total, 135 MW were shipped to the company’s own utility-scale solar power projects.

“Today, we have reached an optimal scale—large enough to maintain a highly competitive cost structure yet lean enough to adapt swiftly to changes in industry dynamics,” said Dr. Shawn Qu, chairman and chief executive officer, Canadian Solar.

Shares fell as Canadian Solar forecast third quarter revenues of $1.6 billion to $1.8 billion, significantly lower than Wall Street expectations of $2.22 billion. The company now guides $6.5 billion to $7.5 billion for full year revenues, falling short of analyst estimates of $7.66 billion.

The company recorded 17.2% gross margin, in line with guidance of 16% to 18%. Its e-STORAGE order backlog grew to $2.6 billion, backed by a record 66 GWh of pipeline, as of June 30, 2024.

Its solar project development arm Recurrent Energy expanded its total development pipeline to 27 GW of solar and 63 GWh of battery energy storage, as of June 30, 2024. The company also achieved initial closing of BlackRock’s investment in Recurrent Energy, representing the majority of the planned $500 million capital infusion. During the quarter, the company also announced a $200 million private placement of secured convertible notes with PAG.

“In our module business, we continue to apply a disciplined approach to operations, from strategic capacity investments to stringent order management. At the same time, we are positioning ourselves for sustainable medium- and long-term growth through our energy storage business, e-STORAGE, and global project development platform, Recurrent Energy,” said Qu.

The company said Recurrent Energy will continue to increase leverage in the near-term to support its transition to a partial independent power producer (IPP) model. As of June 30, 2024, Recurrent Energy’s total solar project development pipeline was 27.4 GW, including 1.7 GW under construction, 4.8 GW of backlog, and 20.9 GW of projects in advanced and early-stage pipelines.

“While we continue to navigate challenging market conditions, our focus remains on sustainable, profitable growth. We are beginning to see signs of market rationalization, as module pricing and input costs reach record lows. In line with our commitment to strategic future planning, we are adjusting certain capacity investments to ensure a resilient financial profile. We anticipate stabilization in the second half of the year,” said Qu.

The NC Clean Energy Technology Center has reported that “increasingly,” utilities are proposing “unspecified ‘clean dispatchable’” generation in their resource plans, with “the most common example” being hydrogen-capable gas combustion units.

The center also reported that U.S. utilities that have recently filed integrated resource plans expect to add 92 GW of solar, 50 GW of wind, and 42 GW of methane gas units. The center did not publicly evaluate whether the amounts of solar and wind for those utilities, over the 15 to 20 years typically covered by a resource plan, could be seen as good news or a disappointment.

As for “clean dispatchable” capacity, the report lists several utilities proposing such projects: Evergy in Kansas and Missouri, Ameren Missouri, PacifiCorp, and Xcel Energy in the Upper Midwest.

One timeline for reaching 100% hydrogen power has been announced by developers of a pioneering project in Utah that is projected to use 30% hydrogen by volume mixed with 70% methane by 2025, and to reach 100% hydrogen by 2045.

Yet a report from the Institute for Energy Economics and Financial Analysis (IEEFA) says “it takes a lot of hydrogen” by volume to cut carbon dioxide emissions. That’s because hydrogen has a lower energy density than methane.

A hydrogen concentration of 50% by volume yields only a 24% emissions reduction, according to calculations by SS&A Power Consultancy cited by IEEFA, and a concentration of 93% is needed to reduce emissions by 80%.

The same calculations show that until 77% hydrogen by volume is reached, “hydrogen-capable” generating units will be powered primarily with methane.

Unknown costs

The IEEFA report documents proposals for “hydrogen-ready” projects from utilities and merchant developers in 18 states.

While the costs of wind, solar and storage are known today, the report says the ultimate cost of any “hydrogen-capable” gas project will not be known for years.

Hydrogen-related power projects, the report says, “require significant additional investments that will be extremely costly for ratepayers, may not actually work and will conflict with readily available and cheaper renewable options.”

The report sees “three key hurdles” that will “slow and perhaps entirely halt the widespread use of hydrogen as a replacement for methane” in turbine generators: inadequate hydrogen supply, a lack of pipeline infrastructure to transport hydrogen, and a lack of capacity to safely store hydrogen.

The pioneering Utah project has addressed those hurdles by co-locating green hydrogen production, hydrogen storage in salt domes, and gas combustion turbines.

The IEEFA report said state regulators should require utilities to compare the costs of hydrogen projects with costs of zero-carbon resources including renewables, battery storage, efficiency and virtual power plants.

Blending high levels of green hydrogen into methane, the report says, that “would consume vast amounts of renewable energy that would be better used directly to replace existing fossil fuel generation.”

Green hydrogen’s role

The policy consultancy Energy Innovation found last year that production of green hydrogen for industrial use can be profitable in much of the US, but did not evaluate hydrogen’s use for electricity production.

Current industrial uses of hydrogen include production of ammonia, largely for fertilizer, and oil refining. Ammonia could also be used as a fuel for shipping. The Green Hydrogen Coalition says that green hydrogen could also decarbonize the production of steel and cement.

The public version of the NC Clean Energy Technology Center’s report is titled “50 States of Power Decarbonization: Q2 2024 Quarterly Report Executive Summary.” The full report is available free to state policymakers and regulators, and to others for a fee.

The IEEFA report is titled “Hydrogen: Not a solution for gas-fired turbines.”

A report on state government- and utility-driven initiatives affecting electric vehicles (including hybrids) shows the majority of such efforts continue to focus on rebates and incentives for consumers and commercial fleet operators to acquire them. However, regulations and actions to modify electricity rates relating to EVs and develop charging infrastructure are also moving forward.

The Q2 2024 edition of “50 States of Electric Vehicles” published by the NC Clean Energy Technology Center (NCCETC) at North Carolina State University said a total of 561 EV actions were taken during the timeline of the report. In 2024, as of early August, 29 states have enacted legislation related to transportation electrification. Massachusetts, New York, California, Illinois, New Jersey, Minnesota, Michigan and Hawaii were the most active in this regard, the report said.While the report shows that governments continue to invest heavily in creating markets and incentives for growing EV numbers, certain trends are showing the effects of these vehicles in the real world. For example, more states are imposing additional registration fees for electric vehicle owners, with most U.S. states now having such fees in effect. Also, a growing number of states are opting to adopt per-kWh fees for electric vehicle charging.

The publicly available executive summary of the $500 report did not identify a cause for these actions; however, it’s no secret that states imposes such charges in order to recoup gas taxes lost from non-hybrid EVs bypassing gas pumps.

The report also shows the growing footprint of EVs on the nation’s electricity grids. Utilities are developing charging programs to manage the EV charging load. The report cites NV Energy’s proposed charging programs as part of its latest transportation electrification plan as well as Xcel Energy’s request for a new active managed charging program in New Mexico. Actions of other utilities proposing to offer EV owners incentives to divert charging to during off-peak hours.

More importantly, a growing number of utilities are filing expansive transportation electrification plans on a routine schedule, the report said, with several states now requiring this.

“As the adoption of electric vehicles continues to grow, so too does the EV focused utility offerings, with an increased focus on active managed charging programs,” Emily Apadula, policy analyst at NCCETC, said in a statement. “These programs allow the utility to directly control a customer’s charging load in order to remotely optimize charging times and reduce stress on the grid.”

Scientists from Colorado State University have conducted field research on vegetable crop growth located below PV modules with varying transparency. The vegetables are grown under thin film, semi-transparent cadmium telluride (St-CdTe) modules with a transparency of 40%, bifacial monocrystalline silicon (BF-Si) modules with a transparency of 5%, and opaque polycrystalline silicon (O-Si) modules with a transparency of 0%.

“Semi-transparent PV (STPV) module technology has emerged as a potential solution to mitigate the negative effects of dense shade in cropping systems while maintaining a high module density,” said the academics. “To our knowledge, this is the first replicated research experiment that evaluates module transparency types in an irrigated vegetable field setting.”

The experiment was conducted over two growing seasons, 2020 and 2021. The study site was located in Fort Collins, Colorado, USA, in a field designated for research. Overall, the growth of six vegetables was tested: jalapeño pepper, bell pepper, lettuce, summer squash, Tasmanian chocolate tomatoes, and red racer tomatoes.

“There were three planted rows across the entire site – north, middle, and south,” explained the group. “Lettuce, peppers, and tomatoes were planted in two offset sub-rows in 0.9 m beds covered with black plastic mulch in the north and south rows. Squash was exclusively planted in the middle row both years with 1.2 m spacing on center.”

As for the PV modules, the scientists used three of each type. They were installed in a set position of 35 degrees facing south, with the bottom edge of the modules 1,220 mm above the ground and the back at a height of 2,360 mm. The ST-CdTe modules had a rated output of 57 W, the BF-Si had 360 W, and the O-Si had 325 W.

“Each of the 12 crop subplots, including both PV arrays and control plots, spanned a width of 4.3 m, with a 4.3 m spacing between adjacent subplots,” the researchers said. “Due to the single pole mount configuration, the shadow cast from the modules moved throughout the day. With this, the crops received direct sun early and late in the day, with maximum shade during the peak hours of the day and immediately under the modules.”

Per the results, the summer squash under all three module types displayed significantly lower yields than the control plot, regardless of the module transparency type. While in the control plot, under full sun conditions, the squash yielded 5.1 kg per plant, it grew 3.2 kg in the BF-Si scenario, 3.2 kg in the O-Si scenario, and 4.1 kg in the ST- CdTe scenario.

The other vegetables had equal or higher average yields to the control under the 40% transparent ST-CdTe treatment but with no statistically significant differences. The jalapeño peppers yielded 155 g per plant in full sun, 161 g in the BF-Si, 155 g in the O-Si, and 162 g in the ST- CdTe, while the bell pepper yielded 295 g per plant in full sun, 294 g in the BF-Si, 278 g in the O-Si, and 346 g in the ST- CdTe.

The lettuce weight per head was 105 g in full sun, 126 g in the BF-Si, 111 g in the O-Si, and 129 g in the ST- CdTe. The Tasmanian chocolate tomatoes had an average of 926 g per plant in full sun, 1,060 g in the BFSi, 1,069 g in the O-Si, and 1,278 g in the ST- CdTe. Lastly, the red racer tomatoes had 867 g per plant in full sun, 733 g in the BF-Si, 903 g in the O-Si, and 962 g in the ST- CdTe.

“The optimization of the agri-PV array with semi-transparent PV modules could increase agricultural production while maintaining the added protection of an energized canopy in traditional APV systems,” the researchers concluded. “More research is needed to better understand the economic tradeoffs between increased module transparency compared to vegetable crop production, while also considering the increased energy yield from module bifaciality.”

Their findings were presented in “Vegetable Crop Growth Under Photovoltaic (PV) Modules of Varying Transparencies,” published in Heliyon.

Terrasmart announced the release of a new hail stow feature for its single-axis tracker,TerraTrak.

The risk of damage to solar plants from hail storms has increased with the frequency of extreme weather evens. Over the past five years, hail damage has caused more than 50% of total insured project losses, said hail risk expert VDE. Though infrequent, these events can produce record losses. In 2022, hail losses exceeded $300 million in Texas alone. Forty-year financial exposure models from engineering firm VDE Americas suggest that hail events could result in up to $13 million in damage at 0° tilt, compared to only $620,000 at 60°.

Terrasmart’s new hail stow capability mitigates that risk with its PeakYield, cloud-based tracker control and monitoring software platform. Terrasmart reports that the hail mitigation system automatically triggers optimum stow position to protect solar assets without requiring operator intervention.

Available for both 1P and 2P trackers, the hail stow solution adds to Terrasmart’s racking portfolio. The portfolio offers both ground screw and driven piles, designed to perform in the most extreme terrain and weather conditions.

“Project de-risking has, and continues to be, our most significant contribution to the solar industry,” says Terrasmart president Ed McKiernan. “Our new hail stow feature adds to our existing array of foundation and racking products that bring unique reliability to unreliable sites.”

Terrasmart outlines the following advantages of its hail stow feature:

• Automatic stow feature puts trackers into safe position without requiring operator intervention, reducing potential lapses from human factors
• High-tilt stow angle accounts for both wind and hail conditions, eliminating contradicting positions and ensuring a safe tracker position (+/- 50° for 1P and +/- 60° for 2P)
• Real-time, cloud-based weather forecast triggers activate based on industry-leading data from Accuweather
• Auto-stow feature activates 60 minutes before a weather event but timing can be customized to meet owner requirements
• Stow function does not require installing additional hardware or calibration over time

“Our motto at Terrasmart is to stow early and stow often,” says Ashton Vandermark, Terrasmart’s software solutions lead. “We are adamant about automatically triggering hail protection to avoid instances where manual intervention has not occurred during storms. We are excited about this latest addition to PeakYield’s cloud-based functionality and machine-learning intelligence to protect assets.”

Terrasmart, owned by Gibraltar Industries, has more than 25 GWs of solar deployed across 6,000 PV systems.

Terrasmart’s software team will be at RE+ in Anaheim September 10 to 12 in booth #D30011 to give live demos of PeakYield as well as discuss hail stow and other TerraTrak features.

Net metering hangs in the balance in New Hampshire A group of interested parties, including the state’s utilities and the Granite State Hydropower Association, agreed on a settlement that calls for the rate to stay the same for two years.

GM signs agreement to match assembly plant power demand with solar The automaker entered a 15-year, 180 MW solar power purchase agreement (PPA).

While the PUC will ultimately rule on net metering, a group of interested parties—including the state’s utilities and the Granite State Hydropower Association—agreed on a settlement that calls for the rate to stay the same for two years.

The settlement also calls for the electric utilities to file a NEM time-of-use rate two years from the approval of what they’re calling NEM 2.1. In response to claims that NEM shifts costs to non-solar ratepayers, the settlement calls for the utilities to impose application fees for net metered projects to reduce the administrative costs borne by non-net-metering customers. Fees suggested range from $200 to $1,000 per project.

The state’s leading clean energy advocacy group, Clean Energy NH, has sent a rallying cry in support of the settlement. Executive director, Sam Evans-Brown told pv magazine USA that he’s hopeful that the commissioners won’t cut the current compensation rate, but he said “we have seen with this commission that they are hostile to certain types of utility programs. This was most evident in their order in the Energy Efficiency docket from 2020, which was overturned unanimously on a bipartisan basis by New Hampshire lawmakers.”

Much evidence has been entered into the record for Docket 22-060, yet Evans-Brown said in the past, the order in the previous docket was not based on any evidence that was entered into the record, so Clean Energy NH is afraid that history may repeat itself.

The history of net metering in New Hampshire goes back to 1998 when NEM, a policy that provides credit to rate payers on utility bills for the amount of solar energy sent to the grid, was first enacted in New Hampshire. At the time it supported both solar generation as well as small-scale hydropower and it provided net credits at the retail rate which was 17 cents per kWh.

In 2017 NH’s NEM was cut to around 14.7 cents per kWh for small (<100 kW) systems and 10 cents per kWh for large projects compared to between 13 and 25 cents per kWh in Maine, and about 16 cents per kWh in Vermont.

Source: Clean Energy NH

While the net metering rate has been low in NH, the cost of electricity is high. New Hampshire currently has the 8^th highest electricity rate in the country, averaging 23.1 cents per kWh.

Furthermore, while solar would ease this cost burden for many ratepayers, the state is not known as a solar energy powerhouse. The state currently gets 1.94% of its electricity from solar, compared to neighboring Massachusetts that gets 23.75% of its electricity from the sun. NH and is ranked 41^st in the nation according to the Solar Energy Industries Association. That rank is expected to drop to 45^th over the next five years.

If the NH PUC chooses to reduce or eliminate net metering in New Hampshire, solar in the state may be affected. pv magazine USA spoke with Dan Weeks, vice president at ReVision Energy, New Hampshire’s largest solar installer. Weeks said that net metering has been “the critical foundation for thousands of families, plus housing authorities, nonprofits, businesses, and towns to go solar and get at least a portion of the value that they provide to the grid back in net metering credits.”

Weeks noted that right now net metering in NH is good through 2040, which is only 15 years away. With 20 years being the “minimum accepted duration for investing in projects,” he said ReVision is hoping the PUC leaves net metering in tact and extends the duration.

“We think that’s a very modest task,” said Weeks. “And the fact that all of the regulated utilities, as well as the consumer advocates, plus industry and environmentalists are in alignment should make it an easy decision for the PUC commissioners. But we’re also reading the signals showing that they could go in a very drastic direction, and that concerns us very much.”

California’s current solar conundrum is an example of what could happen to New Hampshire’s solar market. The updated net metering rule that was implemented in April 2023, called NEM 3.0, cut compensation for exported rooftop solar generation by roughly 80%. Since then interconnection queues show an 80% drop in installation applications. The California Solar and Storage Association (CALSSA) reported that nearly 17,000 rooftop solar jobs, about 22% of the workforce, were lost this year as a result. Solar Insure, which backs many installation companies in the state, told pv magazine USA that its data shows 75% of solar installers are now in the “high risk” category following CPUC’s decision to implement NEM 3.0, with SunPower being the most notable bankruptcy among many.

Comments on the potential rate change can be emailed to ClerksOffice@puc.nh.gov. Clean Energy NH advises that comments be sent by August 30, 2024.

General Motors (GM) announced it has entered a 15-year power purchase agreement (PPA), signing on to purchase electricity generated by a 180 MW solar project.

The agreement with solar developer NorthStar Clean Energy will enable GM to power three of its assembly plants with clean energy. The project in Newport, Arkansas, will support the electricity needs of GM’s Lansing Delta Township Assembly and Lansing Grand River Assembly in Michigan, and the Wentzville Assembly site in Missouri.

The Newport Solar project is expected to generate enough electricity to power over 30,000 homes per year.

“By expanding our renewable electricity portfolio, we are taking a major step forward in reducing our carbon footprint and advancing our broader sustainability goals,” said Rob Threlkeld, GM director of global energy strategy. “This facility not only supports our renewable electricity strategy, but also demonstrates our dedication to a sustainable future for all.”

The project won’t directly power GM plants, but rather will provide GM with renewable energy certificates (REC) that help the company achieve its state environmental, social, and governance goals. Such REC contracts are often facilitated by Southeast U.S. states, where the grid has some of the worst carbon pollution in the nation.

While RECs help attract investment and development in these regions, critics have warned that they are misleading in the purported environmental benefits. Projects often sell electricity and RECs as two separate assets.

GM now has sourcing agreements with 17 renewable energy projects across 11 states. BloombergNEF lists GM as the automotive industry’s largest buyer of renewable power capacity.

D.R. Horton, among the largest new home builders in the United States, announced it has selected Streetleaf as a national vendor. 

In the agreement, Streetleaf will provide its solar-powered streetlamps to D.R. Horton for its new construction communities. 

Streetleaf’s latest streetlamp includes a 21% efficiency solar panel, 220W high-efficiency LED lights, and an NiMH battery. The resilient structure can withstand temperatures up to 158 degrees F and winds of 160 mph. It an be installed at heights 15 to 25 feet and is available in black or white.

“Any housing project being developed without solar-powered streetlights is a missed opportunity for the future of that community,” stated Liam Ryan, chief executive officer of Streetleaf. “The demand for sustainable living solutions is growing exponentially and our streetlights are attracting the attention of potential homebuyers.” 

D.R. Horton already installs smart home technology in every home it builds. Now the company is incorporating smart neighborhood solutions, including solar-powered streetlights from Streetleaf. 

“Sustainable infrastructure is highly attractive to homeowners, and the added peace of mind that comes with knowing the lights are designed to remain operational even during many extreme weather events like hurricanes is equally important,” said Brad Conlon, senior vice president, business development, D.R. Horton. 

Over 7,300 Streetleaf streetlights have already been installed in more than 100 projects across the U.S. This has led to an estimated 2.6 million pounds of CO2 savings compared to traditional streetlights, said the company. 

Mayfield Renewables announced that Jacob Betcher has been appointed as its new chief executive officer (CEO), effective immediately. Betcher is an accomplished engineering professional and proven business leader having been an engineering manager at Generac Power Systems and COO at Apricity.

Startup Enteligent secures $6 million to scale solar EV charging The company offers a DC-to-DC electric bidirectional electric vehicle charger that allows EVs to charge directly from solar panels without the need to convert to AC.

Natron Energy announces $1.4 billion sodium ion battery factory in North Carolina The company will open a 24 GW annual production facility, creating over 1,000 jobs.

Enteligent, a startup offering solar-powered DC-to-DC chargers for electric vehicles, announced it has raised $6 million in capital from investors to scale commercialization of its products.

The recent funds bring Enteligent’s capital raise to $19 million since 2021. The funding round was led by Taronga Ventures, a global technology investor in real estate and infrastructure.

Funds will primarily be used to scale commercialization of the company’s DC-based solar optimization solutions. This includes the company’s signature technology, the TLCEV DC-to-DC bidirectional electric vehicle charger. Enteligent said its product is the first EV charger to be powered directly by DC-source electricity.

The startup has already secured orders for its technology. The company is supplying its long-dwell-time 25kW DC-to-DC EV charger to a large logistics company to power its newly electrified delivery fleet.

Enteligent said that traditional fleet charging infrastructure uses AC Level 2 chargers that require significant engineering planning, long permitting wait times, and high costs. Furthermore, AC charging relies on the vehicle’s onboard AC/DC converter to charge its DC battery, which wastes 10% to 20% of the energy through conversion losses and is often limited to charge rates of 9.6 kW or less.

The company said its direct DC product leans on the inherent efficiency and reliability of DC technology. It avoids the energy conversion losses and equipment costs associated with converting solar energy from DC to AC and back again, which reduces overall expenses and makes clean energy more effective and affordable.

Entligent also manufactures solar rapid shutdown devices, module level power electronics, and other solar balance of systems components.

“Enteligent’s technology sets a new standard in maximizing solar energy efficiency,” said Jonathan Hannam, managing partner at Taronga Ventures. “Their holistic approach to solar power optimization offers practical solutions with real-world applications that meet the needs of global real asset owners and operators. Together, we can significantly advance decarbonization efforts for real assets.”

Natron Energy, manufacturer of sodium-ion battery energy storage systems, announced it will open a $1.4 billion factory in North Carolina.

The manufacturing facility is a planned 24 GW annual production capacity site in Edgecombe County. Once operational, the factory will increase Natron Energy’s production capacity by a factor of 40.

Natron’s batteries are the only UL-listed sodium-ion batteries on the market today, said the company. The batteries are expected to serve a wide range of use cases, including industrial power space, including data centers, mobility, EV fast charging, microgrids, and telecom, among others.

Natron Energy said its battery chemistry presents zero strain during charging and discharge, 10x faster cycling than traditional lithium-ion batteries, and 50,000+ cycle life, and are made without any lithium, cobalt, nickel, or other difficult-to-obtain minerals.

The company said its patented “Prussian blue electrodes” store and transfer sodium-ions faster and with lower internal resistance than any other commercial battery on the market today. 

The project is expected to create 1,000 full-time jobs in the area. The facility is nearly 1.2 million square feet, located on a 437 acre plot in Kingsboro. The factory is expected to be supported by over $50 million in grants from North Carolina.

“After evaluating over 70 sites across 9 states, we found that North Carolina, with its leadership in the clean energy revolution, would make the perfect home for this project. We are proud to partner with the state on this ambitious project to deliver high-quality jobs to the community while advancing the electrification of our economy,” said Colin Wessells, founder and co-chief executive officer, Natron Energy.

The factory is facilitated in part by a Job Development Investment Grant (JDIG) approved by the state’s Economic Investment Committee. Over the course of the 12-year term of the grant, the project is estimated to grow the state’s economy by $3.4 billion.

Natron and the state also anticipate additional support being provided for the project through the first use of the North Carolina Megasite Readiness Program, a new state grant program open to local governments and designed to provide funds to help prepare or upgrade qualifying industrial sites to the competitive level required in today’s economic development marketplace. The state expects Edgecombe County will apply for a $30 million grant from the fund.

“We’re proud to be leading the charge in the advancement of a domestic battery supply chain, and we’re grateful for the partnership of local and state officials here in North Carolina,” said Wendell Brooks, co-chief executive officer, Natron Energy.

US Secretary of Energy Jennifer Granholm is set to join local senators and the governors of Ohio and Pennsylvania this week for the ribbon-cutting ceremony of the Appalachian Regional Clean Hydrogen Hub (ARCH2) Program Office. ARCH2 said in an email that the hub recently received up to $925 million in federal funding, marking a major milestone in its development and the nation’s shift to clean energy.

American Airlines said it will add hydrogen-powered aircraft to its fleet by 2032. The company, part of the ZeroAvia project, has agreed to the conditional purchase of 100 hydrogen-electric engines for regional jets from ZeroAvia’s powertrain development program. “In early 2023, ZeroAvia flew the maiden flight of its 19-seat Dornier 228 testbed aircraft, retrofitted with a full-size prototype hydrogen-electric powertrain on the left wing. Since then, it has completed 13 test flights and has an active certification application with the FAA for this powertrain in aircraft with up to 20 seats,” the company said in its sustainability report.

Marubeni Europower has announced a joint plan with Suntory Global Spirits to develop a small-scale hydrogen plant for decarbonizing whisky production at Auchentoshan Distillery in Scotland. “Public and stakeholder engagement is currently underway on the project, as the team continues to progress the proposals with West Dunbartonshire Council. Timings for the site to be live are to be defined, but it is expected that a planning application will be submitted later this year, with the hope that the hydrogen production facility will be up and running by 2027,” Marubeni Europower told pv magazine.

Cepsa has agreed to sell its Gasib liquefied gas subsidiary in Spain and Portugal to Abastible, a subsidiary of Chilean Empresas Copec, to support its investments in the energy transition. “This transaction is another step in our strategy to become a benchmark in the energy transition, driving investments in sustainable energy such as green hydrogen and biofuels, businesses that we expect to represent more than half of our activity by 2030,” said Cepsa CEO Maarten Wetselaar.

Linde Engineering has signed an agreement with Shell Deutschland to build a 100 MW renewable hydrogen plant for the oil company’s project at the Rheinland Energy and Chemical Park in Wesseling, Germany. ITM Power will supply the PEM electrolyzer stacks. The plant is scheduled to go into operation in 2027, said Linde Engineering. 

Swift Current Energy reported that it has closed on a tax equity investment from Google for its 800 MWdc Double Black Diamond Solar project in southern Illinois. The amount of funding by Google was not disclosed, but previous reporting by pv magazine USA stated that over $779 million in project financing was closed for this project, making it among the largest solar project financings in U.S. history.

Located 30 miles west of Springfield, Illinois, the Project is currently under construction and is expected to reach commercial operations by early 2025. Once operational, according to Swift Current Energy, Double Black Diamond Solar is expected to be the largest solar project east of the Mississippi River.

The tax equity financing makes use of energy communities and domestic content adders, provided in the Inflation Reduction Act.

Energy communities are those that are expected to face challenges in the transition away from fossil fuels, such as certain metropolitan statistical areas (MSA) and non-metropolitan statistical areas based on unemployment rates. The domestic content adder is a 10% tax credit bonus for solar, wind, and battery energy storage developers that install projects using U.S.-made components, adding to the 30% base investment tax credit.

“As we work to responsibly grow our infrastructure, we need to partner with companies like Swift Current who understand the nuances of the energy markets where we operate and can help unlock new clean energy at a rate that matches the pace and scale of demand growth on electric grids today,” said Amanda Peterson Corio, global head of data center energy at Google.

The project uses First Solar modules, a majority of which are being manufactured in the US, as well as solar trackers from U.S.-based Nextracker. At peak construction, the project employed approximately 500 construction workers. Swift Current is the project developer and will be the long-term owner and operator, and McCarthy Building Companies is the engineering, procurement, and construction (EPC) partner.

Swift Current Energy said that Double Black Diamond Solar will contribute to communities in Sangamon and Morgan counties. The Project, capable of powering 100,000 homes annually, is expected to reduce regional carbon dioxide emissions by approximately one million tons per year.

“We are proud to be home to one of the largest clean energy projects in the nation,” said Andy Van Meter, Sangamon County board chairman. “The Double Black Diamond Solar project brings significant economic benefits to our community, contributing $100 million in tax revenue and supporting hundreds of jobs. This project is a win for both our community and the environment.”

Energy producer Constellation NewEnergy reportedly will purchase a portion of the energy and renewable energy credits (RECs) generated by Double Black Diamond Solar to serve the seven customers that have been announced. The City of Chicago will source renewable energy produced by the Project to power several energy-intensive facilities, including Chicago O’Hare International Airport and Midway International Airport. Additionally, Cook County Illinois, CVS Health, Loyola University of Chicago, PPG, State Farm, and TransUnion have agreements to purchase power from the Project via Constellation.

Mitsubishi UFJ Financial Group (MUFG), Societe Generale, Truist and ING provided construction financing for the Project. Vinson & Elkins LLP and Husch Blackwell LLP represented Swift Current in the transaction. Milbank LLP and Bryan Cave Leighton Paisner LLP represented Google.

The California Energy Commission expects to issue flexible demand appliance standards for electric storage water heaters “hopefully” within months, said Michael Sokol, director of the efficiency division at the California Energy Commission (CEC), on a webinar hosted by the Clean Energy States Alliance.

The CEC issued a flexible demand appliance standard for pool controls last October. CEC Commissioner Andrew McAllister said at the time that a standard for electric storage water heaters would be next, noting that ten of the largest heat pump manufacturers had committed to help California reach its goal of 6 million heat pumps for water or space heating by 2030.

Flexible demand appliance standards in California will work in tandem with flexible rates for electricity, enabling appliances to operate when rates are lower, for example when renewable generation is high.

EV chargers, batteries, and more

The CEC has set a tentative sequence for developing flexible demand appliance standards for five more types of appliances, based on “our early analysis” and preliminary stakeholder planning discussions, Sokol said.

The third standard, after pool controls and electric storage water heaters, is expected to cover electric vehicle supply equipment, such as EV chargers. Next would be standards for battery energy storage systems.

The next three standards to be developed would have “end-user time impacts,” Sokol said, namely low-voltage thermostats, electric clothes dryers and dishwashers.

McAllister said last year that California aims to reach 7 GW of load flexibility by combining 3 GW of price-responsive demand from appliances with 4 GW of traditional demand response, in which some customers “drop load” during the 100 highest-demand hours of the year.

A Californian who owns a pool and operated a flexible demand pool control unit on its default schedule would save about $100 per year, Sokol said. Customers will have the ability to override the default schedule and operate a pool control unit at times of their choosing.

CalFlexHub

Much of the research underlying the new standards is conducted by the California Load Flexibility Research and Deployment Hub (CalFlexHub) at Lawrence Berkeley National Laboratory.

CalFlexHub will hold an all-day symposium on September 24.

Most states with renewables targets are meeting them Nearly all states with a renewable portfolio standard have met or nearly met their current standard. Four states have yet to meet their solar carve-out requirements.

U.S. module manufacturers seek “critical” retroactive tariffs Led by First Solar and Hanwha Q Cells, U.S. solar module manufacturers have filed allegations with the Commerce Department, citing “critical circumstances” and suggesting increased module imports due to their previous lawsuit filings.

12 GW of utility-scale solar deployed in first half of 2024, doubling 2023  The Energy Information Administration reports that 20.2 GW of electricity generation capacity was deployed in the U.S. in the first half of 2024, with solar energy leading and energy storage also seeing significant deployments. Fossil fuel retirements exceeded new fossil constructions more than tenfold.

We must onshore the supply chain With the introduction of the American Tax Dollars for American Solar Manufacturing Act earlier this month, senators are trying to close this work-around and put American manufacturing back on a level playing field. 

U.S. solar car race success for two Canadian teams Solar car teams from Canada outperformed in two categories of the latest Electrek American Solar Challenge.

According to the U.S. Department of Energy’s Energy Information Administration (EIA), the U.S. connected 20.2 GWac of utility-scale power plants to the grid during the first half of 2024. This capacity includes 12 GW from solar power, which represents 59% of the total additions. Additionally, 4.2 GW of this new capacity was attributed to energy storage.

Florida and Texas led the nation in utility-scale solar development, contributing 38% of the new solar capacity. Notable projects include the 690 MW Gemini Solar facility in Nevada, which integrates solar and storage, and the 653 MW Lumina Solar Project in Texas.

Energy storage was the second most significant technology by capacity with a total deployment of 4.2 GW. California led the charge, contributing 37% of the total energy storage capacity, followed by Texas (21%), Arizona (19%), and Nevada (13%). Together, these states accounted for 90% of the energy storage capacity added, with the 380 MW battery at the Gemini facility being the largest of the period.

Fossil fuel retirements far outpaced new fossil capacity deployments. The EIA noted that 5.1 GW of capacity was retired, with 53% from methane (2.7 GW) and 41% from coal (2 GW). In contrast, only 0.4 GW of new gas capacity was deployed.

The U.S. energy sector’s growth trajectory is expected to continue its upward trend. For the second half of the year, the EIA forecasts an additional 42.6 GW from new capacity deployments, including 25 GW from solar and an additional 10.8 GW of energy storage. Combined with the first-half capacity of 12 and 4 GW, the nation could finish 2024 with 37 GW of new utility-scale solar and 15 GW of new energy storage facilities.

Is 37 GW real or a mirage?

Whether we can actually reach the projected record capacities of solar will be dependent on politics. The nation is currently debating the imposition of new AD/CVD tariffs, which if implemented at the rates suggested by the filers, would lead to the United States paying three times the international price for solar panels. Historically, similar AD/CVD tariffs led to delays and cancellations for about 20% of utility-scale solar capacity in 2022.

Solar industry analyst Roth MKM has suggested that developers are proceeding cautiously, potentially deferring some 2024 projects to 2025 due to these tariff risks. Just last week, U.S. module manufacturers filed a petition with the U.S. Department of Commerce seeking critical retroactive tariffs.

In 2023, the U.S. added just over 18 GW of utility-scale solar, according to the EIA. Including all capacities, from residential to utility-scale, Wood Mackenzie significantly adjusted their capacity estimations upward to just over 40 GWdc of solar power deployed in 2023. At the start of 2024, the EIA projected about 36 GWac of new utility-scale solar capacity. Combined with small-scale solar projections from various groups, it was suggested that nearly 53 GWdc of new solar capacity might be deployed in the United States in 2024. The EIA indicated that if the current pace continues, then 37 GW of utility-scale solar will be deployed in 2024, more than doubling last year’s record capacity.

Two years ago, the Biden Administration and Congress worked together to begin the process of reshoring solar manufacturing.

For the last 20 years, China has been working hard to secure a monopoly over this critical technology. While China has mostly succeeded, the Inflation Reduction Act (IRA) created a set of incentives to get us back in the game. But, one critical piece may undermine our progress – we are letting China-headquartered companies locate final manufacturing in the United States, taking advantage of those same incentives while preserving their supply chain monopoly over the fundamental components.

Fortunately, with the introduction of the American Tax Dollars for American Solar Manufacturing Act earlier this month, senators are trying to close this work-around and put American manufacturing back on a level playing field.

Solar energy was invented in the United States, but right now nearly all of it, and about 99% of the fundamental component (the wafer), is being manufactured elsewhere, specifically, by Chinese-controlled companies. As our government works to invest in clean energy, we’re incentivizing companies to build back their operations in the U.S. so Americans can benefit from good-paying jobs, foster innovation from our world-leading R&D abilities, and establish energy independence in the critical technologies for our future.

Congress created a remarkably far-sighted system to reshore solar, batteries and wind technology. Policymakers not only created supply-side incentives in the advanced manufacturing production incentive that encourage manufacturers to build big factories quickly, but they paired them with demand-side incentives to give developers who use the products a bonus if they buy the products of those factories as they build solar and wind farms.

Unfortunately, the guidance for that bonus issued by the Treasury Department so far has missed the mark and has now become one of the biggest obstacles to jumpstarting the onshoring of American solar manufacturing. As it stands, Chinese companies can continue to leverage their monopoly power over the fundamental components of solar, produced with weak environmental and labor protections as well as massive direct subsidies, and sell to projects claiming the “domestic content bonus.” The clock is ticking to get this right as billions of investment dollars and thousands of jobs in solar manufacturing hang in the balance. In a very real sense, the future of solar energy depends on it.

China has dominated the solar manufacturing sector for a decade, and they’ve done it using a familiar playbook to those of us who’ve watched what the OPEC cartel has done to oil markets. OPEC’s ability to control price was legendary and it wasn’t limited to keeping prices high. Much more importantly, they could crash prices when they wanted to in order to run out competition. From “heavy oil” in Venezuela, to oil sands in Canada, to fracking in the US, OPEC has demonstrated again and again that you can either join them like Venezuela or be run over, with the attendant economic crash that people in Colorado, New Mexico, and Texas have seen many times over.

Now, China is doing the same thing in solar – as we are currently seeing the lowest prices in history, far below production cost – to stifle our manufacturing renaissance before it gets a chance to take off. Stymying competition and, thus, innovation is chapter one of the cartel playbook and China has perfected their execution.

Look no further than our friends across the pond: nearly all of the European solar manufacturers have closed operations due to insufficient protections from below market Chinese products. Many are even looking to the United States, but that will quickly change if our policies don’t keep pace.

To build a robust solar supply chain in the United States, our government must prove that we have the backs of our manufacturers. Companies will not invest here if they do not think they will be protected. How are U.S. manufacturers supposed to compete when China is setting prices far below the cost of production?

The fact is, international competition is not for the faint of heart. Our companies can hold their own, but only if the government has their backs and helps build the foundation for successful competition. This means leveraging our strengths; our unmatched innovation apparatus, strong investor base, and our brutally efficient market that forces constant improvement. But this only works if we don’t ignore the fact that China simply doesn’t have a free market economy.

Unlike the U.S., where most of our economy is us selling products and services to each other, their entire economic system requires exports, because their consumer class doesn’t have the ability to support their economy. This means, the U.S. government must work to produce a level playing field for U.S. manufacturers through the three legged stool of production support, demand incentives, and tariffs and other trade remedies. For the first time in several generations, we’re on the path to building the supports our economy needs to thrive in these all-important industries – as long as we don’t lose our will to succeed,

No one action can unwind the years of investment that Chinese-headquartered solar firms have made to control the solar industry, but we must act now with every tool at our disposal. By updating the domestic content bonus, enforcing smart trade policy, and standing up to the Chinese-controlled monopoly trying to protect their dominance by doing the minimum possible in the U.S. we can reshore the domestic solar supply chain, ensure the United States is clean energy independent, and secure a future for solar manufacturing in America that will benefit workers, businesses and the environment.

Student solar car teams from Canada’s Polytechnique Montréal and École de technologie supérieure made it to the podium at the Electrek American Solar Challenge 2024, a distance-based competition for solar cars.

With a multiple occupant vehicle (MOV) named Esteban 11, students from Polytechnique Montréal won first place in the MOV category in both the qualifier circuit race, known as the Electrek Formula Sun Grand Prix (FSGP) and in the main race, the Electrek American Solar Challenge, which requires completing a minimum of 1,500 miles (2,400 km).

The Esteban team completed 1,610.3 miles at an average speed of 36.2 mph (58.26 km/h), with an overall score of 73.86. The MOV category is scored on factors beyond the distance covered, such as practicality, amount of external energy used, and whether the 35 mph target average speed was maintained.

The other Montreal team, hailing from École de technologie supérieure, won silver in the single occupant vehicle (SOV) category, completing 2,004.5 miles with the Éclipse XI solar car. The SOV class is scored solely on miles driven. Only in the event of a tie is elapsed time relevant.

This year’s winner of the SOV class was the University of Michigan student team with its Astrum solar car, completing 2,095.5 miles (3,372 km) with an average speed of 37.51 mph.

Esteban 11 by the Polytechnique Montréal student team

The Esteban project spokesperson told pv magazine that the team began competing with a two-seater MOV in 2019. “Switching categories allowed us for more creativity in our design. Being multiple occupants also displays the efficiency of our car. Especially in the event, the broader public gets to learn how the technology evolves,” said the Esteban spokesperson.

The team used a 1218 W solar array with cells from Singapore-based Maxeon and encapsulation by German specialist PV panel manufacturer OPES Solutions. The 4-wheel vehicle weighed 293 kg, measuring 4.92m x 1.8m x 1.04 m. The battery was a 9.2 kWh by China-based BAK Technologies, weighing 47 kg, paired with two 5kW M2096D-3 hub motors from Japan’s Mitsuba in a carbon fiber monocoque.

“One great challenge we had was splitting the battery pack. This allowed us to have a lower center of gravity but complicated the monitoring and protection,” the spokesperson said, adding that a new printed circuit board design adhering to professional standards with features to manage heat effects also made a difference this year.

Éclipse XI by the École de technologie supérieure student team

The Éclipse XI, a 3-wheel design weighing 200 kg, measured 4.5 m x 1.5 m x 1.1 m. It was equipped with a 1000 W solar array spanning 4m2, based on Sunpower Maxeon Gen 3 solar cells. It had a 20 kg 5kWh lithium ion battery by Japanese manufacturer Panasonic.

The Éclipse XI team not only won a silver medal in the American Solar Challenge competition, it also won two awards, an Electrical Design Award, and the Abe Poot Award. The latter is named after an influential figure in the U.S. solar car racing community, that recognizes team spirit of collaboration and cooperation, according to the Éclipse XI team spokesperson.

The Electrical Design Award recognized the performance of the electrical setup. “At FSGP, we were the first team to complete both electrical and battery protection system inspection with all green status. We also proved that our electrical systems were robust and reliable along both races, more than 4500 km without any issue,” the Éclipse team spokesperson told pv magazine.

“For this race, we used a custom-made motor casing with air cooling system to help us climb the most steeped hills along the route,” they said, adding that the team is currently working on an improved maximum power point tracking that will “maximize efficiency across all operating ranges” to be able to reduce overall weight and cost.

The Electrek American Solar Challenge 2024 attracted over 30 student-run teams from the U.S. and Canada. It began on 20 July in Nashville, Tennessee, and ended in Casper, Wyoming, on 27 July. The primary route has 1562.2 total miles to complete and vehicles must average at least 35 mph for the event. There are seven optional loops to earn additional points.

Solar panel manufacturers First Solar, Hanwha Q Cells, Meyer Burger, Mission Solar, REC Silicon, Convalt, and Swift Solar, grouped under the American Alliance for Solar Manufacturing Trade Committee (AASMTC), have filed a new complaint by the Wiley Rein law firm with the U.S. Department of Commerce alleging increased solar panel imports from Vietnam and Thailand as a result of the Alliance’s prior antidumping and countervailing duties (AD/CVD) legal filings.

The AASMTC, citing “critical circumstances,” has filed for retroactive tariffs on all solar panels imported since their filing in April.

The filing states that, due to the April AD/CVD actions, “several China-based companies operating in Thailand and Vietnam appear to have actively accelerated their U.S. solar exports, likely to evade impending duties.” The filing suggests that solar module imports from Vietnam have increased by 17%, while those from Thailand have grown by nearly 40%. In total, the increase relative to the prior months was about 2.6 GW of module capacity.

At the beginning of 2024, the U.S. Energy Information Administration (EIA) and other groups suggested that the U.S. might install 53 GWdc of solar in the upcoming year. If realized, this would represent a 32% increase over the 40 GW of solar deployed in 2023.

Roth MKM, a solar industry analyst, provided insights on the complexities of the situation with an industry lawyer:

The data Wiley is using is not accurate, as it includes product subject to Solar I (i.e., the China case, because of circumvention). So, we have to wait to see what the accurate data says. And, even if DOC ultimately goes affirmative, the ITC also has to reach an affirmative finding, and the ITC rarely finds critical circumstances. So, this will cause (is already causing) havoc in the industry, but will likely turn out to be a flash in the pan.

In 2022, the EIA reported that the threat of AD/CVD tariffs had prompted delays or the cancellation of around 20% of utility-scale solar generation capacity. Solar industry analyst Roth MKM has suggested that solar developers are currently slowing project deployments due to the AD/CVD tariff risks associated with solar module procurement, pushing 2024 installations into 2025.

If the Department of Commerce were to implement the tariffs suggested by the group, it would lead to the United States paying three times the international price for solar panels. ACORE (American Council on Renewable Energy) president and Chief Executive Officer Ray Long said a finding of AD/CVD violation “could unintentionally cede U.S. leadership in the solar industry to other countries.”

Last week, the Biden administration maintained a 14.5% tariff on imported solar cells and increased the volume of cells allowed from 5 GW to 12.5 GW to keep up with growth in solar module manufacturing facilities.

All but three of the 29 states plus DC that have a renewable portfolio standard (RPS) are meeting their current targets, according to an analysis by Lawrence Berkeley National Laboratory.

Vermont’s current RPS target of nearly 60% is the highest of any state, as shown in the featured image above, provided in the analysis. Every bar in the image without a light blue segment at the top means that state has met its current RPS.

The study says that “large shortfalls” in New York and Illinois are “expected to close” as contracted projects come online.

The study counts a state as meeting its RPS if the state’s utilities have retired renewable energy credits (RECs) equal to the amount of the RPS requirement. States award RECs for renewable power generation.

A state may also permit utilities to comply with its RPS by submitting “alternative compliance payments.”

Delaware’s “large shortfall,” the study says, is due to its low cost for alternative compliance payments compared to other states in the region.

Puerto Rico is not included in the analysis but also has a large shortfall in meeting its renewables target. The territory stands at 12% renewables, compared to its current target of 20% by 2022.

Solar carve-outs

Of the 15 states plus DC that have RPS carve-outs that require a certain amount of solar and/or distributed generation, all but four have met or nearly met the goals, as shown in the nearby image.

 Drivers

While the study says that “parsing out the incremental impact of individual drivers” for the growth in renewables generation is “challenging,” it observes that RPS policies have been a “larger driver” of renewables deployment in three regions:

• The Northeast, where almost all renewable capacity additions—mostly onsite and community solar in recent years—are serving RPS demand
• The Mid-Atlantic, thanks to solar carve-out capacity and RPS-certified projects with corporate power purchase agreements, which “potentially sell RECs into compliance markets”
• The West, where added renewables are driven by “aggressive” long-term RPS and clean energy standard (CES) targets throughout the region, and where non-RPS additions are mostly onsite solar.

Regions where RPS standards have been a “smaller driver” are:

• Texas, which achieved its final RPS target in 2008, so that all renewables growth since then is not influenced by the RPS
• The Midwest, where there is “lots of wind development,” some of which is contracted to utilities with RPS needs
• The Southeast, where renewables growth is primarily driven by utility procurement and qualifying facilities under the Public Utility Regulatory Policy Act (PURPA).

In all but two regions, renewable generation well exceeds the combined RPS targets for the states in the region, as shown in this graph from the study:

Ultimate targets

Across the 29 states plus DC with an RPS, 16 have ultimate RPS targets of at least 50% of retail electricity sales, and 4 have a 100% RPS. Sixteen states have adopted a 100% clean energy standard, which can be met by renewables and typically also nuclear and hydroelectric generation as well.

RPS and CES policies will require 900 TWh of new clean electricity by 2050, the study says, “equivalent to roughly 3x the historical rate of RPS buildout.”

In the Chinese market, the majority of module sellers OPIS surveyed said the TOPCon FOB China market was quiet and prices were stable although there were some buyers out in the market talking down prices. Market talks of TOPCon prices below $0.09/W FOB China were circulating in the market, with one buyer pointing out that there were offers of Grade A TOPCon cargoes with a power output of 580-585 W of cargo sizes above 10 MW being offered at $0.081-0.086/W. However, sellers OPIS surveyed said there were no transactions at this level.

Most market discussions continued to be heard at $0.095-0.10/W FOB China. The Chinese Module Marker (CMM), the OPIS benchmark assessment for TOPCon modules from China was assessed at $0.096/W unchanged from the previous week while Mono PERC module prices were assessed stable week-to-week at $0.090/W.

Bearish sentiment prevailed in the Chinese domestic market as recent large-scale public tenders such as China Coal Group’s 4 GW procurement tender had attracted low offers of CNY0.7134 ($0.100)/W for N-type modules and CNY 0.7104/W for P-type modules with many market participants expecting module prices to fall to CNY0.70/W levels in the coming weeks, an industry source said. Mono PERC module prices were assessed at CNY0.777/W, stable from the previous week while TOPCon module prices were assessed unchanged at CNY0.801/W week-to-week.

In the European market, OPIS assessed the TOPCon modules delivered into Europe lower on the week at €0.109 ($0.12)/W, with indications ranging from €0.100/W to €0.120/W While delivered prices have eased in recent weeks due to a seasonal lull, a market source noted that August freight rates are still hovering at high levels compared to the previous few months.

According to OPIS records, August freight rates from China to Rotterdam are around $7000 to $8000 per forty-foot equivalent unit (FEU), approximately $0.0189/W to $0.0192/W, which is 30% higher compared to June. According to a European trade source, TOPCon modules up to Q2 2025 delivery were heard to be around €0.100/W to €0.110/W depending on the project size.

In the U.S. market, spot prices for U.S. delivered duty-paid (DDP) TOPCon modules fell this week to $0.291/W, with indications from $0.260/W to $0.320/W, while prices for Q1 2025 delivery averaged $0.311/W, ranging between $0.280/W and $0.350/W. OPIS assessed the U.S. mono PERC Q4 delivery module prices at $0.249/W, with indications between $0.200/W to $0.295/W, while 2025 delivery cargoes were around $0.27-0.34/W.

A major U.S. buyer said that prices of TOPCon modules from India and Southeast Asia scheduled for shipment this year have dropped recently. Another North American source noted growing concern among developers as autumn nears, particularly regarding the heightened tariff risk from Southeast Asia. Trade officials significantly broadened the scope of AD/CVD investigations this spring, increasing the likelihood of finding anti-market behavior in the four targeted countries. The White House has yet to clarify whether there will be tech exemptions or grace periods.

Tracker monitoring software technology is an often overlooked but crucial element of solar development. New project discussions tend to focus on hardware components such as foundations and mechanical properties, but software capabilities are equally important. Inadequate technology can leave a site vulnerable to risks like weather damage and revenue loss.

Since tracker software is the underlying intelligence that optimizes all facets of a tracker’s performance and maximizes the likelihood of a site reaching its energy goals, it’s the “brains” behind the operation. Integrating the right monitoring software in the beginning can provide important benefits over the entire lifecycle of a project.

The ABCs of tracker technology

A tracker technology system consists of on-site hardware connected to compatible software. If tracker technology is lacking in the basics (i.e., the ABCs,)  it can lead to lower site production and make O&M responsibilities more difficult.

On-site, a coordinated and well-engineered system will include:

• A network controller: The network controller, also called the tracker control unit, is a central hub that connects to row boxes and weather stations for the purpose of collecting data on site and sending that data to the cloud. Network controllers should connect to Supervisory Control and Data Acquisition systems (SCADA).
• Row boxes: Row boxes securely communicate tracking angle status and other variables continuously to the on-site network controller. When assessing a system, ask for what type of data output is received from the row boxes to determine how much a system communicates, and how easy it will be to remotely monitor and diagnose.
• Weather stations: Weather stations equipped with an anemometer, an ambient temperature sensor, and a snow sensor can gather details about on-site weather conditions such as wind speed and snowfall in real time. The stations feed the data to the network controller which in turn sends it to the cloud. A technology partner should be able to recommend a customized number of weather stations based on a site’s size and unique topography.

From there, tracker monitoring software should integrate seamlessly with the tracker hardware, and include an intuitive, easy-to-use dashboard.

The three Ps of tracker software technology

Tracker software benefits fall into three categories – protect, predict, and produce.

1- Protect from weather damage

Tracking technology can enhance a site owner’s ability to prevent weather damage and anticipate changes in weather conditions.

• Prevention: Wind damage is one of the most prevalent challenges that trackers face, and hail is becoming an increasingly significant concern in the solar community. Weather risks are compounded in areas prone to snow and flooding. It is essential that a tracker monitoring system includes the appropriate onsite sensors to safeguard solar assets. Sensors measure ambient temperature, wind activity, and depth of snow or flooding. This information enables timely responses to minimize production loss or damage.
• Forecasting: Forecasting is another critical feature of tracker monitoring. While weather patterns can change rapidly and hail is notoriously hard to predict, features like API integration with AccuWeather help site managers anticipate and proactively respond to changes, such as safely stowing trackers before a storm hits.Storing this weather data in the cloud provides ongoing, valuable insights for future planning.

2- Predict and ease O&M

Tracker monitoring software allows O&M to stay one step ahead of any situation and respond accordingly. Imagine being able to instantly detect when a row is not tracking on its normal path versus days or weeks of production losses due to maintenance issues. Look for predictive features such as:

• Real-time alerts via email or text that notify you of issues or changes
• An in-depth and user friendly dashboard that allows you to see inside the site, view real-time data, and access historical data
• Automatic stow position adjustment when sensors recognize certain thresholds, circumventing potential damage from wind, hail, or snow
• Machine learning capabilities that identify issues such as rows not tracking properly so they can be fixed before they impact performance
• Remote access that allows troubleshooting without going on site
• Zone controls that make it easy to perform routine maintenance like mowing while the rest of the site continues tracking

3- Produce more energy

Tracker software can maximize energy production by improving power output and minimizing downtime and/or damage. A sophisticated system will allow adjustments based on time of day, topography, and angle:

• Backtracking algorithms that minimize row-to-row shading by adjusting to the time of day (.i.e., morning or evening when the sun is low in the sky) prevent shadows from reducing output.
• With perfectly flat sites and level terrain being a thing of the past, tracker software needs to be able to adapt to topography nuances that cause trackers to be higher or lower than its neighbors. Systems that recognize the impact of shading based on topography, and can respond with solutions, add significant value and production gains.

Five questions to ask 

Before making a final commitment, ask these five questions to get the clearest picture of a technology partner’s capabilities regarding its tracker monitoring software:

1. Who owns the technology for the trackers? Is it proprietary, or outsourced? Do you create both the software and hardware, or just one or the other?
2. Can the software be updated to include new features and improved functionality?
3. How accessible is the data? Is it stored in the cloud and easily available to the team?
4. Are there automatic features and integrated APIs that protect against weather damage – such as auto-stow based on sensor data? (Note that manual stow is a big red flag).
5. Does the software offer remote access for easy trouble-shooting, and an easy-to-use interface?

As sites age, the infrastructure ages as well, but software can be regularly updated, enhancing stakeholders’ abilities to protect against weather damage and optimize power production. With tracker monitoring software, owners and site managers are empowered to make decisions based on real-time data and historical details, and can rely on automatic adjustments designed to safeguard solar assets. Choosing tracker monitoring software technology wisely can yield immediate benefits, as well as benefits for years to come.

From ESS-news

he U.S. Department of Energy has granted $147 million to construct an energy storage facility at a shuttered paper mill. The battery energy storage system (BESS) from Form Energy, a Somerville, Massachusetts-based grid-scale energy storage developer, will be able to store enough wind and solar power to serve up to 85,000 homes.

The 85 MW iron-air battery system is both safer and more affordable than its lithium-ion counterparts since it uses abundant iron and oxygen. The battery storage project will be one of the largest of its kind in the world and is meant to support one of the most congested parts of the New England grid.

Form Energy will deploy the 85 MW battery system at Lincoln Technology Park, which can discharge energy for up to 100 hours or just over four days. The Power Up New England program includes strengthening the transmission system to deliver higher power loads from renewable sources, including nearby onshore wind turbines.

According to local media sources, Sen. Angus King, an independent, said the project is a step forward in tackling the increase in extreme weather events in Maine. In December and January just passed, hundreds of thousands of Mainers were left without power for extended periods of time after the devastating storms that hit the state.

Although iron-air battery systems are a nascent technology, iron-air batteries are finding increased attention globally as governments strive to secure grids with renewable energy using energy storage systems from abundant materials.

A recent report in Chinese media describes the metal-air battery industry internationally as showing “great market potential”. Supportive policies for these battery types have been developed in China, Japan and in Europe, while the U.S. has funded the research and development of metal-air battery technology through the Advanced Energy Research Program (AERP).

According to the Chinese publication Sohu.com, the US and Japan are in the leading position globally in terms of metal-air battery technology research and industrialization. While some local news sites in Maine suggest the local population is still skeptical of the project, the operating company, Form Energy, is already building a number of such projects across the United States.

In June 2023, Form Energy announced a definitive agreement with Georgia Power, a Southern Company utility, to deploy a 15 MW / 1.5 GWh iron-air battery into the utility’s Georgia grid, providing a 100-hour dispatch long-duration energy storage (LDES) system. In July 2023, Minnesota’s public utilities commission approved Form Energy’s 10 MW/1 GWh iron-air long-duration energy storage facility construction project for Xcel Energy.

Houston-based Sage Geosystems has started construction on a 3 MW geo-pressurized geothermal energy storage system in Christine, Texas. The announcement follows a land-use agreement signed with the San Miguel Electric Cooperative Inc. (SMECI) enabling the location of the facility near an existing coal-fueled power plant. Sage will serve as merchant, buying and selling electricity to the Electric Reliability Council of Texas (ERCOT) grid.

The storage system, dubbed EarthStore, is based on Sage’s dry rock geothermal technology, which consists of a drilled well into which water is pumped and kept at ambient heat and pressure in subsurface rock formations. When electricity is needed, the naturally heated and pressurized water is released to run a Pelton-type hydroelectric turbine generator. The storage facility is expected to have six to 10 hours of capacity.

The SMECI project will be the company’s first commercial storage facility. Sage CEO Cindy Taff said the coal plant will not have any bearing on storage operations, except as a source of water, and that the idea is to buy electricity from ERCOT to run pumps when demand and prices are low. When ERCOT experiences high demand Sage will run its turbine and sell the power.

“We’ll be drilling the well in September and building the facility,” Taff told pv magazine USA. “We’ll have everything done by the end of December this year.”

Ideally, Taff says, the EarthStore system would serve as a long duration energy storage companion to solar and wind generation, where surplus energy is used to run the pumps. The amount of storage depends on the number of wells available: more may be drilled to increase capacity on site. The pumped water may be stored indefinitely and when released delivers a round-trip efficiency of 70-75% with a water loss of less than 2%, she said.

The EarthStore system is one of family of geothermal storage and baseload energy systems Sage is developing. A more ambitious geothermal generation technology drills a series of wells to depths of 9,000 to 20,000 feel, where ambient temperatures range from 218- to 485-degrees Fahrenheit. In such systems, pressurized steam is liberated to run Rankin-cycle turbines to generate electricity. A more advanced version will heat pressurized, supercritical CO2 to drive a specialized turbine with greater efficiency.

Sage has contracts with the Department of Defense to develop geothermal baseload generators and microgrids for its facilities. It is conducting feasibility studies at the Army’s Ft. Bliss and Air Force’s Ellington Field bases, both in Texas. A prototype geothermal plant is under construction at the latter site. In addition, Sage has a test site of its own in Starr County.

According to Taff, the primary advantage of Sage’s approach to geothermal storage and generation is that it uses existing drilling techniques from the oil and gas industry to produce renewable energy from rock formations that exist essentially everywhere. All of the 16 GW of existent geothermal energy is produced from hydrothermal locations linked to volcanic activity – relatively rare occurrences.

“If you look at the continental U.S., we can put storage even in the East, where the geothermal potential is a little bit more challenge,” Taff said. “We can do it in the West, where you have good geothermal potential. So, we can pair with wind or solar just about anywhere. We are actually looking at pairing with solar to provide off-grid, 24/7 power for data centers and other customers who need tons of power.”

A recent headline in this publication stated that “community solar increases energy equity.” It is true that incentives and legislation ensure that community solar projects are built to include low- to middle-income (LMI) communities in a meaningful way.  And undoubtedly, the “middle income” part of “LMI” are benefitting from access to clean, low-cost solar power.

I do believe that the growth statistic referenced in the article – from two to 10% participation by LMI subscribers – is the result of a carrot and stick approach that has made it either a requirement or a bonus for community solar project developers to actively include traditionally underserved communities.

While this growth metric is significant, it may not be indicative of the reality for low–income households. When looking at the data, the question remains – how many of these LMI subscribers are actually middle income, rather than low income – the truly underserved?

Today, a host of frictions exist that make it really challenging to include low income households in a meaningful way. In fact, because of these frictions, it was surprising to read another statistic in the article; that the cost of acquiring LMI customers for community solar projects had declined by 30% between 2022 and 2023.

Our experience shows that engaging LMI households often requires significantly more handholding, which can translate to higher costs. This need for a higher touch isn’t surprising as these communities have historically been taken advantage of, so they approach a new service with great skepticism. Then, they often encounter a host of requirements that solidify this point of view, and make enrolling and keeping them as subscribers difficult.

Billing challenges

In many states, low-income households who enroll in community solar programs receive two bills: one from their community solar provider to pay for the community solar credits applied to their utility account; and one from their utility reflecting any remaining usage/bill spend not offset by the community solar credits. We’ve already introduced complexity – and from their perspective, the possibility of paying more – simply by introducing a second bill.

However, the issues do not stop there. Community solar credits applied to a bill in June might not be invoiced until August when the utility actually shares required data. Subscribers, understandably, can be confused since credits don’t reconcile with their most recent bill.

Some states, like New York, have instituted net crediting, a streamlined method for implementing community solar credits where savings are applied directly to the subscribers’ bill.  In this scenario, a subscriber who receives a $100 community solar credit would realize the $20 (or 20%) savings on their primary utility bill. The $20 would simply be applied to the subscriber’s bill as savings and the $80 would be paid by the utility to the project owner. From the subscriber’s perspective, nothing changes and the savings are easy to see.

Unfortunately, net crediting is still the exception, not the norm. In New York, the New York State Energy Research and Development Authority (NYSERDA) have worked with community solar project managers like PowerMarket to advocate for approaches, like net crediting, that make the process easier for the LMI households who would most benefit from credits and discounts.  States including Maryland, New Jersey, and Illinois are in the process of implementing net crediting. I am hopeful that more states follow suit.

Misguided consumer protections

In many cases, a number of states have had to react to bad actors in the retail supply and rooftop solar industries. These states have developed community solar programs with well-intended but inherently flawed consumer protection rules that have also created unnecessary roadblocks for subscribers. In llinois, for example, regulations require interested consumers to navigate a disjointed, digital-only enrollment process. For seniors who may not have an email address, or LMI households without reliable access to internet service, this creates friction from the start.

Illinois requires interested subscribers to first execute a unique, online-only Disclosure Form (DF). This DF creation process presents material barriers to households without computer access or technical savvy. In fact, if you are a subscriber who doesn’t have an email address, like many seniors, you need to sign an additional form representing as much.

In other states, including Massachusetts and Maine, the utilities, citing consumer protection and privacy, do not share critical subscriber usage and bill spend data with community solar managers, resulting in allocations that do not accurately match subscriber’s usage. In some cases, this translates into subscribers paying for credits that then expire. Or in other cases, consumers miss out on additional savings they could be enjoying if only their allocation could be increased. Without the data, however, community solar managers are simply relying on historical usage, and have no ability to adjust allocations as usage naturally fluctuates.

Reducing friction and increasing profitability

Community solar availability is absolutely increasing – not just for LMI households but for many other residential and corporate users. Tax incentives, regulatory requirements, and adders are certainly increasing access and usage.

However, real momentum will come when two things are addressed: reducing challenges for low income subscribers; and increasing profitability for developers.

The industry should unite in a call to action to regulators and legislators: reduce frictions that are hampering growth in equitable community solar access. A host of positive developments in different markets can serve as lessons-learned for the industry as a whole. There are states where regulators have instituted net crediting, enhanced data sharing between utilities and subscriber management organizations, and carved multiple avenues for humanely proving eligibility for LMI discounts. In these states, underserved households and individuals are finding it easier and more attractive to access the benefits of community solar.

Real change ultimately will be driven by looking at and learning from how community solar programs are administered in a creative and effective way. As these smart approaches to our industry proliferate nationally, we should begin to see real, explosive growth around community solar. Let’s work together to ensure that developers and underserved communities both benefit.

Jimmy Carter, champion of solar energy At the age of 92, President Carter’s dedication to solar energy came full circle when his family decided to convert 10 acres of their peanut farm into a 1.3 MW solar farm.

Making perovskite solar PV circular from the start Department of Energy’s National Renewable Energy Laboratory researchers used a circular economy framework to determine how to scale, deploy, and design metal halide perovskite solar panels to be easily recyclable in the future.

Heliene to procure U.S.-made solar wafers from NorSun The NorSun wafers will be supplied from the company’s planned 5 GW wafer factory in Tulsa, Oklahoma.

NorSun, a solar wafer manufacturer signed a multi-year contract with Heliene, a solar module maker. The exact amount of wafers was not specified, but Heliene reported that the supply will meet its annual requirement of silicon wafers starting in 2026.

Heliene has been manufacturing solar modules in Ontario, Canada since 2010 and in Mountain Iron, Minnesota since 2018. Last year the company announced an investment of an additional $10 million to expand its manufacturing and assembly line at its Minnesota facility.

Minnesota Line One was first installed in 2018 at 150 MW and has now doubled in capacity to 300 MW with the recent investment. Line One is situated contiguously to a second 500MW line installed in 2022. The company reports that the upgrades will improve the efficiency of the line.

The NorSun wafers will be supplied from the company’s planned 5 GW wafer factory in Tulsa, Oklahoma. In June NorSun announced plans to invest $620 million the new silicon ingot and solar wafer manufacturing facility on a 60-acre greenfield site in Tulsa, Oklahoma.

Production at the new NorSun plant is expected to begin in 2026, bringing much-needed U.S.-made silicon ingots and wafers to the supply chain, as well as 320 jobs to the Tulsa area. NorSun reports that production can be expanded up to 10 GW.

Heliene, will take delivery of the wafer at its cell factory to be built in the Greater Minneapolis-St. Paul, Minnesota metro area.

“NorSun and Heliene are both dedicated to developing low carbon, domestically produced solutions based on sustainable value chains free of forced labor,” said Erik Løkke-Øwre, CEO of NorSun. “In the months leading up to final decisions at the end of 2024 it is now important that further policy measures are taken to regulate the US market to make sure the IRA program can take full effect”

Norsun, founded in Norway in 2007, specializes in the production of monocrystalline ingots and wafers for ultra-high efficiency solar cells. Its U.S. expansion was facilitated by the Oklahoma Department of Commerce and Tulsa Airports Improvement Trust.

Researchers at the U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) used a circular economy framework to determine how to scale, deploy, and design future metal halide perovskite solar panels to be easily recyclable.

As initiatives to commercialize metal halide perovskite (MHP) solar technology are underway, especially efforts to ensure durable performance in the field, NREL researchers initiated a study of sustainability design factors as another important aspect of commercialization.

“Our goal with this perspective paper was to point out that existing technology does not prioritize building products with sustainability and circularity up front. It was not developed specifically to minimize waste or use the lowest energy processing steps,” Joey Luther, the research’s corresponding author, told pv magazine. “However, since PV is inherently a sustainable technology, now is the time to begin to evaluate how we can develop the commercialization of MHPs with sustainability in mind.”

The group performed the evaluation based on a a prototypical single-junction MHP module close to commercial designs, framed with mounting rails in a glass-glass module configuration with polymer encapsulants, and edge sealing typical of silicon and cadmium telluride panels. The individual PV cells are integrated via scribing, and include front glass coated with a transparent conductor, the MHP layer sandwiched between electron and hole transport materials and a back electrode.

In addition, the team drilled down into constituent chemicals, molecules, and materials typically used in perovskite A, B, and X sites.

For all of the above, sustainability aspects were evaluated, such as energy intensity of manufacturing, carbon intensity, rare mineral mining, recyclability, earth abundance, cost, fossil fuel derived, fail-safe encapsulation, health hazards, and flammability among others.

The prototype was further evaluated based on critical material concerns, embodied energy, carbon impacts and circular supply chain processes. The analysis included the frame, rail materials, front and back glass, encapsulation polymers, solvents, electron and hole transport materials, and electrode materials.

In an information-rich table, the team detailed how the eleven “Rs” of circularity for photovoltaics can offer opportunities and advantages within sustainable manufacturing. An adaptation of the “reduce, reuse, recycle” concept, some of the Rs discussed are listed here: refuse fossil fuels and carbon-intensive materials; reduce energy, material, and carbon input, repair or design for repair, reuse, repower, restore, and recover energy.

When it comes to recycling, the researchers noted that ‘recycling’ includes both downcycling to lower-value, or lower-quality, products. They explained that recycling is beneficial when recovered feedstocks replace virgin materials, which require energy-intensive refining. There is room for improvement. For example, PV glass manufacturing is still using virgin sources in new PV glass products and not post-consumer PV glass cullet, they noted.

The team identified five key areas and opportunities to pursue. The first is enhancing MHP module reliability to meet current commercial PV lifetime standards. Second, investigate the supply chain of low-trade-volume raw materials, such as cesium, and ensure adequate accessibility for the sustainable scale-up of a given MHP composition, or focus research, to reduce or substitute. Third, seek alternatives to indium. Fourth, explore how to accelerate PV glass recycling without downcycling. And fifth, further improve module remanufacturing processes.

“A reasonable combination of these solutions would enable MHP-PVs to contribute meaningfully and sustainably to the energy transition,” stressed the team.

The scientists asserted that “circularizing the PV supply chain, particularly through recycling and remanufacturing glass”, provides opportunities to lower the embodied energy and carbon of MHP-PVs. “Improvements in lifetime and reliability remain paramount for the energy transition and provide the largest benefits,” they concluded.

The perspective is detailed in “Sustainability pathways for perovskite photovoltaics,” published by nature materials.

In the late 1970s Jimmy Carter, a peanut farmer from Plains, Georgia, became the first American president to champion solar energy as a key to energy independence. His bold initiatives set the stage for the future of renewable energy in the United States.

At the age of 92, President Carter’s dedication to solar energy came full circle when his family decided to convert 10 acres of their peanut farm into a 1.3 MW solar farm. Florida-based J&B Solar was chosen to build this impressive array.

The story of this collaboration began on February 8th, 2017, when President Carter and his family attended the groundbreaking ceremony for the new solar project. Developed under a lease agreement with Atlanta-based SolAmerica, the project covered 10 acres and promised to produce over 55 million kWh of energy over the next 25 years. J&B Solar installed 200 concrete foundations, assembling aluminum racking, and positioning 3,852 polycrystalline solar panels. This setup was designed to generate more than half of the power needs for the residents of Plains, a small town with a population of 683.

Reflecting on this milestone, Carter, the soft-spoken 39th president, expressed his hope: “I hope that we’ll see a realization that one of the best ways to provide new jobs — good-paying and productive and innovative jobs — is through the search for renewable sources of energy.”

Carter’s presidency laid the groundwork for the solar industry. A former nuclear submarine officer with a background in science, he understood the potential of advanced technology. In 1977, amidst an energy crisis, he established the Solar Energy Research Institute (SERI) in Golden, Colorado, and set an ambitious goal to install solar energy in over two and a half million homes by 1985. He even installed solar panels on the White House, a symbolic act of “walking the talk.”

Today, the photovoltaic industry thrives on a global scale, driven by more than just government incentives. The collaboration on the Carter family farm is a testament to the enduring impact of these trailblazers, showing how far we’ve come and how much potential lies ahead.

It has been two years since the passage of the Inflation Reduction Act of 2022 (IRA), and like any complicated and multi-faceted policy, the IRA is a mixed bag of successes and failures. Let’s start with the successes.

The IRA created a tax credit transfer market, and it is thriving.  Our firm has closed almost $5 billion in tax credits transfers across over 40 deals. For our deals, the high price is 97 cents on the dollar and the low is 83 cents on the dollar. Much of the difference in price depends on the quality of the indemnity that backstops the buyer’s purchase of the tax credits. The high end of the range has investment grade indemnitors/guarantors or a tax credit insurance policy, while the low end of the range has an unrated indemnitor that is not backstopped by tax credit insurance.

The Treasury issued final regulations about tax credit transfers, but “the credit” really goes to Senator Joe Manchin (I-WVa) who decided that such things were better handled by the private sector than the IRS. In contrast, the activity around “direct pay” (i.e., a refund from the IRS) for tax-exempt project owners, clean energy component manufacturers, carbon capture and hydrogen projects is anemic. The eligible participants are, generally, avoiding direct pay due to concerns about the time it will take the IRS to process the direct pay requests and potential haircuts.

Tax credit transfers have been a success despite Treasury’s regulations consistently favoring tax policy over stimulating clean energy. Examples of that include the approach to the passive activity loss rules that limit the ability of individuals to buy tax credits that is even stricter than the passive activity loss regulations themselves: the transfer regulations preclude an election to “group” hours for an individual to reach the active threshold, while the passive activity loss regulations actually allow such an election for activities the combination thereof is an “appropriate economic unit.”

Further, Treasury’s regulations prohibit combining a lease pass-through (also known as an inverted lease) investment tax credit election with transferability (or direct pay), even though that election is provided for in the tax code.

The other gaps in the Treasury regulations are (i) that we don’t know whether the IRS is going to audit tax credit buyers or sellers (sellers make more sense, but buyers have the money) and (ii) we don’t know whether transaction costs for tax credit transfers are deductible.

Further, Treasury’s online registration portal is backed up, and Treasury is telling registrants that it can’t process registrations for 2024 until October because it has 2023 registrations it needs to process before the extension the buyers and sellers of tax credits that accrued in 2023 have to file their 2023 tax returns are up in September for partnerships and October for corporations.  The resourceful tax credit transfer industry is finding ways to work around these issues.

A related goal of the IRA was to democratize tax equity. The IRA has made progress in that direction but has not fully succeeded.  Thinly capitalized solar developers may be able to access the tax credit transfer market after paying a tax credit insurer, a tax credit transfer broker, a law firm and for investment credit deals, an appraiser.  While well-capitalized solar developers can probably pull it off with a law firm and for investment credit deals an appraiser.  Thus, the well-capitalized developers likely raise five cents or more on the dollar versus their thinly capitalized competitors.  It may sound small, but over time it compounds and leaves the well-capitalized miles ahead.

The 10% tax credit adder for projects built in “energy communities” appears to have been mostly successful. For the most part, developers are able to determine whether their projects qualify for that adder and are able to monetize the adder in the tax credit transfer market. This is due to Treasury publishing guidance that is relatively clear and based on objective standards. Further, we are seeing projects developed on closed coal sites and in communities with a history of significant fossil fuel employment.

At the moment, the 10% domestic content tax credit adder is a split decision.  The domestic content adder appears to have spurred the construction of a flurry of factories making solar modules and batteries, but most of those factories are not online yet.

Treasury’s original guidance on the domestic content adder was unworkable. To address that safe harbors were promulgated for solar, onshore wind and batteries. The safe harbors for solar and onshore wind seems to be viable. There is some cautious optimism about the safe harbor for storage. Technologies like geothermal heat pumps, fuel cells, renewable natural gas and offshore wind do not currently have a safe harbor and find themselves unsure about how to determine eligibility for the domestic content tax credit adder.

IRA failures

Grab a stiff drink and let’s turn to the IRA’s failures.  First, based on anecdotal evidence, the prevailing wage and apprentice rules are not creating much value for the nation.  Most folks building solar projects are already being paid wages not much different than the Department of Labor’s prevailing wage due to a tight market for skilled labor.  Therefore, the prevailing wage rules are burdening the solar industry with concerns about a foot fault in their record-keeping resulting in large penalties or worse yet a reduction in the tax credits a project is eligible for by 80%, while not stimulating higher wages for skilled tradesman needed to build solar and other clean energy projects.  It has created a cottage industry for consulting and accounting firms to verify the appropriate wages are being paid, but the nation was already facing a shortage of accountants.  Let’s not even discuss the shortage of tax lawyers.

In terms of apprentices, it appears most projects are qualifying for an exemption from the apprentice requirements because apprentices are not available. Therefore, the well-intentioned rules do not appear to be spurring America’s young people to forego video games for learning a trade. Thus, the apprentice rules create a concern for project developers and their contractors about a costly tax credit foot fault while not spurring a renaissance in the trades.  If solar and the other clean energy technologies are needed to save the planet from climate change, should we be burdening projects deploying these technologies with cumbersome requirements that are not resulting in more skilled tradesmen?

Finally, there are the proposed investment tax credit regulations.  Those regulations fail to clearly answer some basic questions the industry has been asking for years like how much of a solar parking canopy qualifies for the investment credit.  Further, Treasury has gone out on a limb requiring all equipment integral to a project to have a common owner and only allowing tax credits for repairs and upgrades if less than 20% of the improved project has its origins in the original equipment.

However, the investment credit regulations appear to have what is something of an unexpected gift. The Department of Energy (DOE) seems to have prevailed upon the Treasury to broadly interpret the rule about the investment credit for interconnection costs.  The apparent motivation for this is to spur improvements to the nation’s anachronistic grid.

The statutory allowance for the investment credit on interconnection costs has a 5 MW capacity threshold. However, the proposed regulations appear to say that threshold is applied at the inverter level for solar and the turbine level for wind. For instance, it appears that a solar project that most industry participants would say has 200 MWs of capacity (i.e., it exceeds the 5 MW threshold) would qualify, so long as no inverter is serving 5 MW or more (e.g., there are 50 inverters each serving 4 MW).  This interpretation appears to have been confirmed by the proposed section 48E regulations (i.e., the tech neutral investment credit).  However, many law firms’ tax opinion committees are by nature conservative and are waiting to bless “will” level opinions under the traditional section 48 until Treasury confirms the favorable interpretation in the final section 48 regulations.

The implementation of the IRA has resulted in a range of policies outcomes. However, as is usually the case, the nimble and creative have faired well, while concerns about whether the nation is doing enough to address existential threat of climate change remain unabated.

Pivot Energy partners with Microsoft to develop up to 500 MW of community solar  The portfolio is planned to be developed in locations across the United States from 2025 through 2029.

Community solar developer Pivot Energy announced it has entered a five-year agreement with Microsoft to deploy up to 500 MW of community solar projects. The projects are planned to be developed in locations across the United States between 2025 and 2029.

Over 20 years, the 500 MWac is expected to produce more than 1 billion kilowatt hours of electricity annually, which is enough energy to power approximately 90,000 homes a year. This is equivalent to removing approximately 165,000 gas-powered passenger vehicles off the road each year, said Pivot Energy.

The agreement is Pivot’s largest renewable energy credit (REC) agreement to date. It also marks Microsoft’s first major distributed generation portfolio investment. Microsoft will purchase RECs generated by the projects for a 20-year term. By matching customer electricity usage with new renewable electricity generation, Microsoft supports its goal of reducing Scope 3 emissions by more than half by 2030.

Pivot will develop approximately 150 solar projects in 100 communities across 20 states, including Colorado, Maryland, Illinois, Delaware, Pennsylvania, and Ohio. The first projects are expected to come online this year.

“We believe the clean energy transition can and should benefit communities across the United States that have been historically excluded from economic opportunity,” said Adrian Anderson, general manager, renewables, Microsoft. “Through our work with Pivot Energy and with its commitments to driving community impact, this collaboration helps to build more inclusive, local economic growth across 100 communities while addressing the sustainability needs and opportunities within those communities.”

The agreement outlines four overarching community-centric initiatives that Pivot said it will prioritize:

1) Increasing the diversity of its subcontractors.

2) Partnering with workforce development organizations and subcontractors to train and hire local diverse talent.

3) Partnering with Sustain Our Future Foundation to invest in equitable community initiatives.

4) Increasing the energy bill savings of the community solar projects directed to low-income subscribers.

“An economy fueled by clean, distributed energy can do more than provide power at low cost; it drives growth and success in communities across the nation,” said Tom Hunt, chief executive officer, Pivot Energy.

EagleView, a provider of aerial imagery and analytics, and Aurora Solar, a platform for solar sales and design, announced the launch of EagleView Powered models through the Aurora Solar Platform.

This new modeling capability is the result of the partnership between the two companies when, in March of this year, it was announced that Aurora would make use of EagleView’s high-resolution imagery taken from its aircraft fleet.

Aurora Solar, established in 2013, offers a cloud-based platform that uses lidar-based vision and machine learning algorithms to streamline the process of selling solar.

By adding EagleView’s 3D home modelling technology into Aurora’s platform, Aurora reports it can provide roof models that predict final details of the project installation and solar electricity production output for homeowners.

“We understand that improvements in cost and trust are essential to the growth and healthy functioning of the solar industry,” shared Piers Dormeyer, CEO of EagleView. “We know we can help solve this challenge because we’re in our third decade doing the exact same thing in roofing and insurance.” 

EagleView can leverage oblique and orthogonal imagery. The company said it has used its patented technologies to develop over three billion images. It provides “truth in accurate property measurement and analytics solutions” not only in the solar industry with Aurora but also in roofing, insurance and other industries.

EagleView reports that its geospatial data and imagery library encompasses 94% of the U.S. population and that its technology portfolio comprises more than 300 patents.

The Connecticut Attorney General has initiated legal action against two individuals and three companies for committing multiple crimes, including impersonation of homeowners and unauthorized installation of solar panels.

The state’s lawsuit targets Sierra Howes and Dakota Grumet, principals at Elevate Solar Solutions, Bright Planet and Sunrun, the company responsible for the installations and system ownership. This action addresses three distinct cases in Connecticut, namely the Windsor, Stafford Springs and Wethersfield transactions.

In one particularly bold instance, known as the Windsor Transaction, Howes and Grumet proposed a residential solar project costing $306 per month to a homeowner who rejected the offer. Subsequently, an employee from Bright Planet is alleged to have forged the homeowner’s digital signatures. The lawsuit also includes a recorded call of a Bright Planet employee impersonating the homeowner to Sunrun:

The Sunrun representative then asks Sierra Ford to put the consumer on the line to confirm the details of the transaction. The consumer is female. However, the voice purporting to be the consumer’s on the recorded call is a deep male voice. The voice purports to confirm the consumer’s name, but erroneously reverses the first and last names, as was done on the contract.

On October 9, approximately a week after the deceptive call, Sunrun, notably efficient on this occasion, installed a 14.22 kW residential system without permits.

The Stafford Springs and Wethersfield transactions similarly showcase unethical practices. In Stafford Springs, a homeowner consented to a solar agreement, but claims to have never received a contract to review, later discovering the total cost would exceed $135,000 over 25 years. In both instances, the solar panels were installed in late 2022 without initial permits, which were only later approved by local authorities. To date, neither system has been activated.

In all three instances, the solar modules are still on the respective homes. The Attorney General’s complaint enumerates fifteen counts of legal violations, with four charges each against Sunrun, Bright Planet and Elevate Solar Solutions. These charges include unfairness, deception, per se violations (violations that are inherently illegal), and willfulness.

In the broader context of door-to-door sales, several U.S. states have taken similar legal actions. Minnesota, for instance, recently sued four of the nation’s largest solar finance companies. Vision Solar has faced lawsuits in multiple states, including Connecticut and Arizona. Additionally, Vivint Solar, prior to its acquisition by Sunrun, was sued in New Mexico. Most recently, Rhode Island enacted a law requiring background checks for residential solar salespeople.

ChargePoint introduces Omni Port universal EV charger The connector is compatible with all major electric vehicle brands, including Tesla and non-Tesla vehicles.

ChargePoint, a provider of one of the largest EV charging networks in the United States, introduced Omni Port, an electric vehicle charging connector solution designed to be compatible with all major EVs.

Omni Port eliminates the hassle of carrying a charging adapter or having to dedicate parking spaces for different charging types. The port is available at no incremental cost, the company reports, and is now a standard feature of ChargePoint products.

“With Omni port, ChargePoint solved the challenges associated with a multiple connector environment, ensuring Tesla and non-Tesla drivers can continue to expect a world-class driver experience,” said Rick Wilmer, chief executive officer, ChargePoint.

ChargePoint designed the charging station to seamlessly adapt to each EV. Drivers enter their vehicle’s make and model into the ChargePoint app, tap to charge, and the charging station automatically releases the correct connector type. For users that would prefer not to use an app, a credit card payment option is available at the station.

Omni Port is built into both AC and DC charging stations. The charger enables full support for vehicles with 800 volt architecture, enabling max charging speeds for sustained periods.

The are more than 5.5 million EVs on roads in North America, more than half of which are equipped with J1772 or CCS1 charging ports. As automakers attempt to align on a single connector type for the future, these 5.5 million drivers need assurance that they will be able to charge when they need to. Omni port gives drivers and station owners peace of mind by combining these most common connector types into a single solution.

ChargePoint said Omni Port will begin to ship by the end of 2024. It can be retrofitted on ChargePoint CP6000 and Express Plus Power Link 2000 models at a “nominal cost.”

A research team has determined that covering the world’s highways with solar roofs could generate 17,578 TWh per year, which is more than 60% of global electricity consumption in 2023.

Their study, titled “Roofing Highways With Solar Panels Substantially Reduces Carbon Emissions and Traffic Losses,” was recently published in the journal Earth’s Future. It explores the potential to install solar panels above highways and major roads.

With more than 3.2 million km of highways worldwide, the researchers calculated the costs and benefits of constructing a solar panel network using polycrystalline solar panels with a 250 W capacity. The analysis found that covering highways with solar panels could generate more than four times the annual energy output of the United States and offset 28.78% of current CO2 emissions, while also reducing global traffic deaths by 10.8%.

“This really surprised me,” said Ling Yao, a remote sensing scientist at the Chinese Academy of Sciences and the study’s lead author. “I didn’t realize that highways alone could support the deployment of such large photovoltaic installations, generating more than half of the world’s electricity demand, and greatly easing the pressure to reduce global carbon emissions.”

The researchers also identified regions such as eastern China, Western Europe, and the US East Coast as the most ideal for deployment, despite challenges related to setup and maintenance costs. Yao noted the importance of pilot programs to demonstrate the practicality of this concept.

The research team consisted of academics from the Chinese Academy of Sciences, Tsinghua University and Chinese Academy of Geosciences, all located in Beijing, as well as New York’s Columbia University.

A research group led by scientists from Purdue University has created a novel model for assessing the growth of corn in agrivoltaic facilities and has proposed to use a spatiotemporal shadow distribution (SSD) model to optimize crop yield and power production.

The new method is based on the agricultural production systems simulator (APSIM) plant model, which is based on finer temporal resolution, with literature reportedly supporting its validity. The SSD model, which accounts for the shadow cast by the PV panels, was used in conjunction with the National Renewable Energy Laboratory (NREL) radiation data. These combined data were then calibrated and validated with the results from their field measurements.

The field experiment was conducted at an agrivoltaic farm at Purdue University in West Lafayette, Indiana, USA. There, PV panels were deployed in two arrangements, either 300 W modules placed adjacent to each other or 100 W modules arranged in an alternate checkerboard pattern. They all used single-axis trackers and are 6.1 meters high. The set-up was tested between April and October of 2020.

“For validation, 12 plots are considered,” the academics said. “Corn ears of three representative plants from each of these plots were hand-collected. Overall, 570 corn plants from the without-PV region and 36 corn plants from the with-PV region, respectively, were used in the analysis. The ears were cleaned, imaged, and processed using a DuPont pioneer ear photometer.”

The field measurement showed that the corn yield from the area without PV was measured to be 10,955 kg/ha, compared with the yield of 10,182 kg/ha of the PV area. That was in reported agreement with the novel model, which predicted 10,856 kg/ha for the no-PV area and 10,102 kg/ha for the agri-PV field.

The researchers then used the model to test the impact of the tracker height, distance between arrays, panel angle, and the activation of the tracking system on yield. They first found that designs that lower the tracker height without impeding the movement of plant machinery should be envisioned as the overall average corn yield is a weak function of the tracker height up to 2.44 m.

“However, the variability from one corn row to another increases as the tracker height is reduced,” they further explained. “Another interesting finding is that for our PV module sizes, increasing the distance between the adjacent PV rows beyond 9.1 m, while keeping the total power over the entire land constant, does not lead to an increase in corn yield based on the total land area.”

They also found that anti-tracking (AT) around solar noon provided the most significant increase in the corn yield. “However, this increase in corn yield of 5.6% is quite modest and should be weighed against a substantial decline in solar power,” the group emphasized.

The proposed model was presented in “Optimizing corn agrivoltaic farming through farm-scale experimentation and modeling,” published in Cell Reports Sustainability. The research group also included academics from Denmark’s Aarhus University.

U.S. President Joe Biden issued a proclamation to holds tariff on crystalline silicon PV cells that at 14.25% while allowing up to 12.5 GW to be imported, up from 5 GW. These include cells whether or not partially or fully assembled into other products, and is effective as of August 1, 2024.

The solar tariffs date back to 2018 when signed into law by former President Donald Trump. The purpose of section 201 of the 1974 trade act was to limit imports while giving the U.S. time to ramp up a domestic solar supply chain. It wasn’t until four years later after the Biden administration passed the Inflation Reduction Act (IRA) of 2022 that a domestic solar supply chain began its upward trajectory.

In April the American Alliance for Solar Manufacturing Trade Committee coalition, made up of a group of manufacturers led by Qcells, signed a petition that alleged that four Southeast Asian nations are exporting dumped goods from China, making it difficult for domestic manufacturers to compete on cost. The companies said the current “manufacturing renaissance” in the United States is under threat from heavily subsidized Chinese cells and modules that are alleged to be in infraction with antidumping and countervailing duty (AD/CVD) law.

The IRA’s tax credits and incentives have encouraged clean energy manufacturing in the United States with many companies announcing solar module manufacturing facilities. Earlier stages in the supply chain, however, like raw polysilicon, ingots, wafers, and solar cell manufacturing  have lagged, creating gaps in the domestic supply chain. The new proclamation is intended to “further facilitate positive adjustment to competition from imports of certain crystalline silicon PV cells,” while U.S.-made solar cell capacity ramps up.

Near $1 billion solar cell factory announced in New Mexico Ebon Solar will invest $942 million in a solar cell manufacturing facility, bringing over 900 jobs.

Rhode Island has enacted the “Residential Solar Energy Disclosure and Homeowners Bill of Rights Act” to protect homeowners from predatory door-to-door sales tactics in the solar industry.

The law applies to any individual selling a solar system purchase agreement, a lease agreement, or a power purchase agreement (PPA). It covers anyone soliciting a homeowner or selling a solar project for up to four individual housing units simultaneously. Notably, the law does not apply to solar lease deals with payment terms of less than five years, transactions that involve a generator, or commercial systems.

The law requires all parties selling residential solar to register with the state and renew the registration annually. For the solar company, at least one person in charge of residential sales must have their name and address on file with the state. Additionally, all individuals directly selling to homeowners must undergo a national background check, including fingerprinting, which must be submitted to the Federal Bureau of Investigation. The registration process will be managed by the Rhode Island Division of Taxation.

The Department of Business Regulation is authorized to investigate complaints, impose administrative penalties, revoke registrations, and order violators to cease operations. The department can also impose fines of up to $5,000 per violation for up to four years after the violation has occurred.

The law mandates that specific documents be provided to homeowners. A hard copy or email of the solar agreement must be given to the homeowner. Additionally, the state will issue a standard disclosure form that must include the following information:

• A statement indicating whether operations and maintenance are included in the agreement.
• A written estimate of projected savings over the system’s expected lifespan.
• An estimate of savings beyond the system’s anticipated useful life.
• Data fields used to calculate the savings projections.
• The electricity escalation rate applied in the savings assumptions.
• Information on tax credit eligibility.

Additionally, the new law gives residential customers the right to rescind or cancel the deal for seven days after entering the agreement.

The law goes into effect in March 2025.

The bill was prompted by an increase in consumer complaints regarding aggressive and misleading sales tactics by some solar companies. By implementing these regulations, the state aims to build public trust and encourage the adoption of solar energy while protecting consumers from unscrupulous actors. Attorney General Peter F. Neronha, along with other state officials, has emphasized the importance of these protections in fostering a reliable and transparent solar industry in Rhode Island.

Several other U.S. states have taken action against door-to-door sales companies. Minnesota recently sued four of the nation’s largest solar finance companies. Vision Solar has been sued in multiple states, including Connecticut and Arizona, while Vivint Solar, prior to its acquisition by Sunrun, was sued in New Mexico. Sunrun, along with several other solar door-to-door companies, has also been sued in Connecticut.
