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.

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.

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.

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

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.

DCE Solar “roof-friendly” solar mount passes key safety certification The Eco-Top rooftop mounting structure is designed for commercial and industrial rooftops.

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.

DCE Solar announced its Eco-Top rooftop solar mounting structure has achieved UL 3741 certification, placing the product in compliance with National Electric Code (NEC) 2020 standards.

The Eco-Top rooftop mount structure is designed for commercial and industrial rooftops. It is a ballasted racing system with durable recycled rubber ballast pads. DCE Solar said the mounts are designed to be roof-friendly, protecting the integrity of a roof by leveraging aerodynamics and structural performance to minimize roof loading. The mount uses recycled rubber ballast pads that limit vibration and protect the roof membrane and uses decreased ballast blocks and attachment counts to limit roof penetration and damage.

DCE Solar said its system requires five times fewer mechanical attachments and ballast blocks, resulting in material and labor savings of $0.03 to $0.06 per watt.

The company offers two main options – the Eco-Top High Density, which increases capacity by up to 20% with more wattage per square foot, and the Eco-Top-MR for metal roofs.

All structural components are constructed from g115 galvanized steel. An integral wind deflector minimizes system loading and also functions as a ballast tray, providing a location to place ballast in the array.

The structure is fastened via serrated flange heads. It has built-in vibration resistance and integral grounding and bonding, and all nuts are wax coated to eliminate galling.

The structure is rated for an average dead load of 3.5 psf, or 90 mph wind. It enables flat, 5 degrees, or 10-degree angle tilt. It has a 14 inch or 18 inch shade spacing. The Eco-Top mount supports all major module brands.

“Passing the UL 3741 certification for our Eco-Top Roof-Top solution underscores our dedication to safety, innovation, and efficiency in the solar industry,” said Bill Taylor, chief executive officer, DCE Solar. “This certification not only validates the quality of our product but also provides our customers with the confidence that they are investing in a top-tier, secure solar solution.”

DCE Solar is a U.S. manufacturer of solar ground-mounts and roof-mounted racking systems, founded in 2009. Find a product sheet for the Eco-Top here.

Ebon Solar, a Delaware-based solar cell manufacturing company, released a joint announcement with New Mexico Governor Michelle Lujan Grisham that it will open a manufacturing facility in the Southwest.

New Mexico, which has become a center for advanced manufacturing particularly for silicon computer chips, will now become home to an Ebon Solar facility spanning 834,000 square feet.

Over $942 million will be invested to create the facility, which is expected to generate 900 full-time jobs. The project is developed in Albuquerque’s Mesa del Sol industrial development area.

The Albuquerque Regional Economic Alliance (AREA) served as a key project management partner throughout Ebon Solar’s market evaluation process, facilitating many visits, interviews, and data analysis of the region and site selection support.

“We are thrilled to welcome Ebon Solar to the market; it not only represents a significant capital investment and new jobs to the community but aligns with PNM’s sustainability goals,” said Don Tarry, president and chief executive officer of electric utility PNM and the 2024 AREA Board Chair.

The Ebon Solar factory addresses a critical early upstream stage of the solar panel supply chain. Solar panels are made in a process from raw polysilicon mining, to refining into ingots, cutting into wafers, manufactured into cells, and finally assembled as modules.

While module assembly plants are opening in droves in the United States, with total cumulative capacity growing 71% nationwide in Q1 2024 alone, the need for earlier stages of the chain to be addressed becomes clear. However, cell manufacturing and other early-stage manufacturing processes are quite expensive to build and operate, as evidenced by Ebon Solar’s nearly $1 billion price tag.

(Read: “Can the U.S. fill its domestic solar supply chain gaps?”)

“Ebon Solar is proud to be an innovator in technologies that support renewable energy,” said Judy Cai, chief executive officer, Ebon Solar. “The choice of Albuquerque for our investment aligns with our commitment to sustainable innovation, and New Mexico offers abundant solar resources, favorable renewable energy policies, and a dedicated, skilled workforce.”

Sinovoltaics, a Hong Kong-based quality assurance services firm, released the third edition of its Sinovoltaics PV inverter manufacturer financial stability ranking, featuring 32 manufacturers. The ranking is based on publicly available information on publicly traded companies.

The top ten inverter manufacturers are China’s Hoymiles Power Electronics, Irish energy management specialist Eaton, U.S.-based microinverter specialist Enphase Energy, China-based Kstar Science and Technology and Taiwan-based Delta Electronics, followed by China’s Sinexcel, Switzerland-based ABB, China’s Goodwe, France’s Schneider Electric and U.S.-based Emerson.

In this edition, Schneider Electric is new to the top ten, coming up from fifteenth to ninth.

Sinovoltaics notes that the report, which is global in scope and calculated since September 2021, provides insight into how the financial strength of inverter manufacturers has evolved over the past three years. The report is free to download.

The ranking is based on a so-called Altmann Z-score, a quantitative formula that uses multiple corporate income and balance sheet values to measure the financial health of a company. Sinovoltaics assesses a company’s financial strength through a credit-strength test based on profitability, leverage, liquidity, solvency and activity ratios.

A score that is 1.1 or lower indicates a higher probability of bankruptcy within the next two years, while a higher score of 2.6 or greater indicates a solid financial position.

Sinovoltaics has published several other manufacturer rankings for the quarter, including reports focused on battery manufacturers and module manufacturers. It notes that the financial ranking does not indicate the quality of the equipment, rather they are meant to be used as an element of the due diligence process, or to help identify financially stable partners.

SEG Solar officially opened its new photovoltaic module manufacturing facility in Houston on August 8 with a gala event featuring a ribbon-cutting ceremony and live country music. The automated factory line has an initial capacity of 2 GW of n-type panels per year with plans to expand to 5 GW by 2030.

“You see this facility?” said Jun Zhuge, SEG’s founder and chief operating officer, addressing an audience of mostly customers, partners and local officials gathered for the opening. “We have invested $60 million right here in Houston. We’re not just talk.”

The new factory and headquarters complex features 145,000 square feet of manufacturing and warehouse space and 16,000 square feet of office space. The fully automated production line – SEG claims it’s the longest PV line in the world – takes in glass and cells and runs through production stages over conveyor belts all the way through framing and packaging. There are numerous stations for various inspection and quality assurance processes. The hands-off line requires 12 technicians to attend the machinery, although more were on hand for training purposes.

“We don’t just want to make money,” Zhuge said. “We want to build solar manufacturing in this country. We want to bring all of the supply chain to this country.”

Conceived by co-founders Zhuge and Jim Wood, who serves as chief executive officer, SEG Solar was launched in California in 2016. Through 2021 the company established cell and module factories in Southeast Asia and China. The photovoltaic cells that feed the Houston operation are sourced from Indonesia, but the company says it is committed to producing cells in the U.S.

A veteran of investment banking and solar installation businesses, Wood eventually went to work for a large Chinese solar manufacturer. He teamed up with Zhuge and other partners with industry experience, and they decided there was a real opportunity to establish a successful American module producer under the right circumstances.

“We looked at a lot of the lessons that we’ve learned from myself and other folks here working at other manufacturers and we said, we’re going to lean heavily into automation,” Wood told pv magazine USA, adding that the production machines are the largest of their types available. “Those stringers are 1.3 times faster than any other stringers in the world. So because we’re fully automated, because the capacity of those lines are larger, because the machines run faster, we’re able to be as competitive here as we would be in Southeast Asia.”

According to Wood, the company looked at other regions to establish its U.S. manufacturing base but decided that Houston offered a number of key advantages for SEG Solar’s strategic development plans. He cited Houston as having one of the best ports in the country, a large and educated labor force with many skills and a very friendly business atmosphere. Moreover, Texas is already the second largest solar market in the U.S. with 42 GW installed as of Q2 2024, according to the Solar Energy Industries Association, and is poised to become number one next year.

Wood stresses that SEG Solar’s purpose is not to satisfy domestic content requirements or circumvent tariffs. It is a 100% U.S.-owned company, with the principals assuming financial as well as managerial responsibility for its operations.

“SEG is financed internally,” he said. “We don’t have private equity. There are no external owners. We haven’t taken any outside debt. We’re a true American company where we’ve taken our profits, recycled them and grown this business organically.”

The U.S. Department of Energy (DOE) Loans Programs Office (LPO) announced a conditional commitment for a loan guarantee of up to $1.45 billion to Qcells to support its North American solar manufacturing expansions.

The loan guarantee is offered through LPO’s Title 17 Clean Energy Financing Program, which includes financing opportunities for innovative energy and supply chain projects and projects that reinvest in existing energy infrastructure.

The company is developing a solar ingot, wafer, cell, and solar panel manufacturing facility, supplying each stage of the solar supply chain from raw polysilicon to end-user components. The facility, located in Cartersville, Georgia, will be the largest ingot and wafer plant in the United States, addressing critical early stages of the supply chain.

Once fully operational, the facility is expected to produce 3.3 GW of solar panels per year. This is roughly enough solar capacity to power half a million U.S. households, said the company. It is also equivalent to reducing emissions from power generation by more than 5 million tons of carbon dioxide per year.

The project is expected to support 1,200 construction jobs and, upon completion, 1,950 full-time operations jobs. Approximately 40% to 50% of the construction work has been awarded to local contractors, including contractors from Atlanta, Georgia and Chattanooga, Tennessee. According to an economic review by the Cartersville-Bartow County Department of Economic Development, the investment will create nearly 6,800 jobs in Bartow and Whitfield Counties and has a potential sales output of more than $2 billion.

Panels produced at the site will be designed for both distributed and utility-scale applications. Qcells is also among the largest utility-scale project developers for both solar and storage in the United States with over 2 GW of projects developed or constructed and a project development pipeline of over 10 GW. The company has entered into an 8-year, 12 GW solar and engineering, procurement, and construction (EPC) agreement with Microsoft to be fulfilled with solar panels made in Cartersville.

Components produced by the project are expected to benefit from the 45X Advanced Manufacturing Production Tax Credit. Qcells’ products produced at the site are also expected to contribute to project eligibility for the domestic content 10% tax credit bonus.

“Since IRA’s passage, over 325 GW of manufacturing capacity has been announced across the solar supply chain, representing more than 31,000 potential jobs and nearly $16 billion in announced investments across 111 new facilities or expansions,” said a press release from DOE.

While this conditional commitment indicates DOE’s intent to finance the project, DOE and the company must satisfy certain technical, legal, environmental, and financial conditions before the Department enters into definitive financing documents and funds the loan.

Senate committee approves bill to improve permitting of energy projects The bipartisan legislation is designed to speed up permitting by setting deadlines and doubling production targets for renewable energy permitting on federal lands while not compromising environmental review or community needs.

Bill aims to cut 45X tax credits for Chinese solar makers While the lucrative tax credits has attracted clean energy manufacturers from around the world to build factories in the U.S., the fact that many of the new manufacturing facilities are from Chinese companies has created a controversy that this new bill aims to solve.

Data center power loads threaten corporate net-zero goals The International Energy Agency (IEA) projects that by 2026, data centers will consume more than 800 TWh annually, more than double their consumption in 2022.

A bipartisan group of U.S. lawmakers introduced the American Tax Dollars for American Solar Manufacturing Act, aiming to prevent Chinese solar module manufacturers from claiming subsidies for their American factories.

The Inflation Reduction Act, passed in 2022, offers manufacturing 45 X tax credits for solar components made in America. While the lucrative tax credits have been attracting clean energy manufacturers worldwide to build factories in the U.S., the fact that some of the new manufacturing facilities are from Chinese companies has created a controversy that this new bill aims to solve.

The bill was introduced by Senators Sherrod Brown (D-Ohio), Bill Cassidy (D-LA), Jon Ossoff (D-GA) and Rick Scott (D-FL), seeks to protect U.S. solar manufacturing by removing the tax incentives for Chinese companies and from other “foreign entities of interest” would not be able to receive the 45X tax credits.

“By reshoring the solar supply chain, we can bolster solar manufacturing in the U.S. and ensure our country is not dependent on China for a technology that was invented here and accounted for half of our new grid energy additions last year, said Mike Carr, Executive Director of the Solar Energy Manufacturers for America (SEMA) Coalition.

The Defend Solar USA Alliance also supports the new legislation. The Alliance said in a release that while the 45X tax credit has contributed to the largest investments in factory production in nearly 100 years, it’s estimated that Chinese-controlled companies could collect more than $100 billion in federal tax credits. These credits, the Alliance contends, were “designed to support U.S. clean-energy manufacturers”.

“We shouldn’t be in the business of rewarding China at the expense of our domestic solar industry,” said U.S. Army General John Adams (ret.), and Board Member of the Defend Solar USA Alliance. “The bipartisan bill would ensure that Americans’ taxpayer dollars stay right here at home rather than help subsidize a foreign government’s efforts to put domestic manufacturers out of work. By building a successful domestic solar industry, the U.S. can break from its reliance on foreign energy sources, strengthen our supply chain and reduce our vulnerability to geopolitical conflicts.”

Electric vehicle and energy storage maker Tesla initiated its Megafactory in Shanghai in December 2023 and completed the signing ceremony for land acquisition. Once delivered, the new plant will span an area of 200,000 square meters and come with a price tag of RMB 1.45 billion. This project, which marks its entry into the Chinese market, is a key milestone for the company’s strategy for the global energy storage market.

As demand for energy storage continues to grow, the China-based factory is expected to fill Tesla’s capacity shortage and become a major supply region for Tesla’s global orders. Moreover, as China has been the largest country with newly installed electrochemical energy storage capacity in recent years, Tesla is likely to enter the country’s storage market with its Megapack energy storage systems produced in Shanghai.

Tesla has been scaling up its energy storage business in China since the beginning of this year. The company announced its construction of the factory in Shanghai’s Lingang pilot free trade zone earlier in May, and signed a supply deal of eight Megapacks with Shanghai Lingang Data Center, securing the first batch of orders for its Megapacks in China.

Currently, China’s public auction for utility-scale projects saw fierce price competition. The quote for a two-hour utility-scale energy storage system is RMB 0.6-0.7/Wh ($0.08-0.09/Wh) as of June 2024. Tesla’s product quotes are not competitive against the Chinese manufacturers, but the company has rich experiences in global projects and a strong brand impact.

Heliene, a solar panel provider serving North America, and Premier Energies, a solar cell manufacturer based in India, announced a joint venture to produce solar cells in the United States.

The solar cell manufacturing facility is expected to produce an annual aggregate capacity of 1 GW of N-Type cells to supply Heliene and Premier’s solar cell requirements.

Heliene currently sources solar cells from Premier’s Hyderabad facility for use in module manufacturing at its Mountain Iron, MN location.

“Premier Energies has been a valued partner of Heliene’s for many years now and we share a commitment to providing the highest-quality, most-reliable products to solar customers. With demand for U.S.-made modules and components growing, now is the perfect time to embark on the next phase of our partnership with this joint venture,” said Martin Pochtaruk, CEO of Heliene.

Under the joint venture, Heliene will contribute construction, project management, human resources, financial resource and management, facility operations, supply chain and logistics, and regulatory expertise. Premier will contribute cell technology engineering and operational expertise in the manufacturing process of the cells, manufacturing equipment selection, financial resources, raw material vendor relationships and supply agreements management.

The Inflation Reduction Act of 2022 has tax credits and incentives designed to encourage clean energy manufacturing in the United States. Many large companies have announced solar module manufacturing facilities, but earlier stages in the supply chain like raw polysilicon, ingots, wafers, and solar cell manufacturing facilities have lagged, creating gaps in the domestic supply chain. The Heliene/Premier partnership brings critical solar cell manufacturing capacity to U.S. shores.

Sinovoltaics, a Hong Kong-based technical compliance and quality assurance service firm, has released its third quarter PV Module Manufacturers Ranking, which is global in scope and covers 65 panel suppliers, 6 more than the previous ranking. The report is available to download for free. Results are calculated based on publicly available information from September 2021 to June 2024 to provide insight into the stability of the scores over time.

In this edition, the analysts highlighted four module manufacturers that made improvements, such as U.S.-based Mission Solar’s shift to tenth spot from twelfth, India-based Tata Power Solar up from position 37 to 30, and Taiwan-based Ritek climbed from 47 to 44.

The top of the financial stability chart features four manufacturers from India, Abhishek Corp, Insolartion Energy, Waaree Renewable Technologies, Solex Energy, followed by U.S.-based First Solar, which moved up a notch into fifth from sixth place. Next is Taiwan-based Tainergy, which had the top spot last quarter, now in position six. It is followed by Eterbright Solar Corporation, Taiwan-based TSEC, and two newcomers to the top ten, Vietnam’s Boviet Solar and U.S.-based Mission Solar.

The Sinovoltaics financial stability ranking uses a so-called Altmann Z-score, a quantitative formula that relies on several corporate income and balance sheet values to measure the financial health of a company. It assesses a company’s financial strength based on public information through a credit-strength test based on profitability, leverage, liquidity, solvency, and activity ratios. A score that is 1.1 or lower indicates a higher probability of bankruptcy within the next two years, while a higher score of 2.6 or greater indicates a solid financial position.

The Sinovoltaics analysts note that while the rankings do not say anything about the actual quality of PV equipment, buyers and other industry stakeholders, such as financial institutions, can use the ranking reports as part of the due diligence process or to help identify financially stable partners.

ReCreate, a joint venture between the founders of U.S.-based Create Energy and EU-based Recom Technologies, announced in mid-June a plan to build a 5 GW solar module and cell manufacturing facility in Portland, Tennessee. Create Energy is the brainchild of Dean Solon, who previously grew Shoals Technologies Group from a Tennessee-based startup to a publicly listed PV BOS manufacturer in January 2021. Hamlet Tunyan is the CEO of Recom Technologies, a European module manufacturer.

pv magazine spoke with both solar entrepreneurs on the future factory at last month’s Intersolar 2024 in Munich, Germany.

“In the first quarter of 2025, we will have two module assembly lines operating at the factory, with up to 2 GW capacity,” Tunyan said. “We will then begin cell production within 18–24 months.” For the deployment of the cell lines, ReCreate will potentially acquire another building.

The company will initially source solar cells from Asia, excluding China. “We could even import cells from Korea,” Tunyan stated. “We have to meet increasing module demand in the United States,” Solon added. “Project developers are currently in trouble, and we want to provide them with reliable products.” Increased tariffs on solar modules imported from Southeast Asia threaten to limit their supply to the US downstream market. Southeast Asian manufacturers account for 80% of solar components in the US.

Solon also explained that the ReCreate modules produced at Create’s facilities will be part of a combined package from Create Solutions. This can include equipment EPCs require for their projects, such as transformers, switchgear, MBOS, BESS, and EVSE. “Create Energy along with Create Solutions, wholly owned subsidiaries of Create Holdings, are a one-stop-shop where you can source all the equipment and services needed for renewable energy projects,” Solon said.

The module production facility will initially produce TOPCon panels, although ReCreate may also consider adding heterojunction (HJT) or back contact (BC) products to its portfolio. “Wherever the module technology is going, that’s where we’re heading; we’ll always be on the leading edge,” Solon and Tunyan specified.

He also revealed that, in the future, ReCreate’s modules will be used in what they call “next-gen” PV systems. “Create’s vision is to provide solutions that navigate labor constraints and maximize system reliability at the lowest installed cost per kW,” Solon said. “This will include optimizing the interplay between modules, trackers, power stations, and other integrated systems.”

At his own venture, Create Energy, Solon is charging ahead with disrupting the energy storage and microgrid markets. NanoGrid, the company’s first product, will be the microgrid solution for a top-tier Japanese car manufacturer, extending to dealerships across North America. According to Solon, NanoGrid involves “canopy and rooftop solar, battery energy storage, and site-load monitoring tied to level 2 and level 3 EV charging solutions.”

In addition to starting Create Energy, Solon also anchored the formation of Neos Partners following the IPO and his departure from Shoals. Neos raised $830 million as a private equity fund that has invested in six companies to date, a very impressive track record for a fund that closed in spring of ’23. Solon refers to this collection of target companies as an “un-evil empire” providing transformers, switchgear, EPC, and engineering services. “Create’s clean-tech products are reimagining renewables beyond utility infrastructure to the power-starved EV, data center, and artificial intelligence (AI) markets,” said Solon.

As Solon revealed in Munich, ReCreate modules and cells are just the beginning. “Made in Tennessee” batteries seem to be in the works as well and the focus will be on providing complete EV, PV, and BESS solutions from Create Energy to the North American & EU Markets, supplying large-scale EPCs, renewable energy developers, and Commercial and Industrial (C&I).

First Solar, Inc. commissioned its new research and development (R&D) innovation center in Lake Township, Ohio, which the company says is the largest facility of its kind in the Western Hemisphere.

The Jim Nolan Center for Solar Innovation is dedicated to the late James “Jim” F. Nolan, a former member of First Solar’s Board of Directors and the architect of the company’s cadmium telluride (CdTe) semiconductor platform.

According to a study by the National Renewable Energy Lab (NREL), in 2023 CdTe represented  about 16% of the U.S. solar market. First Solar is a leader in CdTe technology and differentiates itself not only by the use of the thin film technology, but also by its vertically integrated manufacturing process, domestic production and commitment to responsible solar. At the company’s California Technology Center (CTC) in Santa Clara, First Solar recently achieved a 23.1% efficient CdTe cell, a new world record certified by NREL.

“Thin films are the next technological battleground for the solar industry because they are key to commercializing tandem devices, which are anticipated to be the next disruption in photovoltaics,” said Mark Widmar, chief executive officer, First Solar. “While the United States leads the world in thin film PV, China is racing to close the innovation gap. We expect that this crucial investment in R&D infrastructure will help maintain our nation’s strategic advantage in thin film, accelerating the cycles of innovation needed to ensure that the next disruptive, transformative solar technology will be American-made.”

The new research facility covers 1.3 million square feet and includes a high-tech pilot manufacturing line allowing for the production of full-sized prototypes of thin film and tandem PV modules. Prior to the commissioning of the Jim Nolan Center, First Solar was using a manufacturing line at its Perrysburg, Ohio facility for product development efforts. With a dedicated R&D center, First Solar expect to “accelerate innovation cycles.”

The company reports that it will have approximately a half-billion dollars invested in R&D and that building out R&D infrastructure will create approximately 300 new jobs by 2025, the majority of which will be located at the Jim Nolan Center.

First Solar is also involved in perovskite solar development after announcing last year the acquisition of Evolar, the Swedish perovskite specialist. First Solar said in a statement that the acquisition will accelerate the development of next generation PV technology, including high efficiency tandem devices. It aims to integrate Evolar’s know-how with its existing research and development streams, intellectual property portfolio, and expertise in developing and commercially scaling thin-film PV.

In addition to R&D planned at the Jim Nolan Center, the company expects to also commission a perovskite development line at its Perrysburg, Ohio, campus in the second half of 2024.

First Solar reports it has invested almost $2 billion in R&D, operates laboratories in Santa Clara, California, and Perrysburg, Ohio, in the US, and Uppsala in Sweden.

At the end of 2023 First Solar had 16.6 GW of annual global nameplate manufacturing capacity and is expected to achieve over 25 GW of capacity by 2026. First Solar expects to commission new manufacturing facilities in Alabama in the second half of 2024 and Louisiana in the second half of 2025, bringing its total U.S. nameplate capacity to 14 GW by 2026.

Volytica, Sinovoltaics launch new analysis service for 100% battery pack review at factory  The newly launched BESSential analysis goes deeper than traditional Factory Acceptance Testing (FAT), which is performed at the container level. The service evaluates each battery energy storage system pack down to the cell level and detects and corrects thermal, electrical, and capacity imbalance issues.

From ESS News

Hong Kong-based technical compliance and quality assurance service firm Sinovoltaics and German cloud-based battery diagnostics software provider volytica have teamed to develop a battery energy storage system (BESS) analysis service, offering 100% pack review.

According to the developers, their BESSential analysis detects and corrects thermal, electrical, and capacity imbalance issues directly at the BESS factory and goes beyond typical Factory Acceptance Testing (FAT), which is performed on the container level.

While FAT involves extensive electrical and performance tests at the factory to ensure the battery systems meet industry standards, “they can miss smaller defects and abnormal behaviors that may not become apparent for years,” the companies argue. What is more, some BESS integrators only perform sampling performance tests and can miss underlying issues in subsystems, racks, or battery packs that emerge after installation.

“Even a minor defect at the cell level can jeopardize an entire BESS investment. Our BESSential 100% pack analysis mitigates this risk, protecting the client’s physical asset while also securing their return on investment,” said Arthur Claire, director of technology at Sinovoltaics.

BESSential collects and compiles the vast amount of data from the FAT and then goes a step further to evaluates each pack down to the cell level. It can identify volatility in individual battery packs and cells, such as temperature shifts, voltage irregularities, capacity imbalance, and other factors predictive of battery defects.

These metrics are then used to model the micro-environment of each battery pack. Any anomalies that are found are flagged in the system for further inspection.

SolarEdge Technologies, a smart energy provider that produces solar inverters, module-level power electronics, power optimizers and energy storage announced it has reached significant growth milestones following the passage of the Inflation Reduction Act (IRA) of 2022. 

Nearing the two-year anniversary of the passage of IRA, the company announced it has created 1,500 new U.S. jobs, with 1,750 total new jobs expected by the end of 2024. 

SolarEdge is now manufacturing in the United States through global electronics contract manufacturers. A facility in Austin, Texas opened in late 2023 and has reached a quarterly production rate of 50,000 residential Home Hub inverters in Q2 2024.  

A second facility was opened in Seminole, Florida. When fully ramped, it is expected to produce about 2 million domestic content power optimizers units per quarter. The company said it has plans to begin commercial inverter and power optimizer production at the Florida facility in 2025. The two facilities together have shipped their first 20,000 power optimizer units. 

“As a global company, we are proud to invest in American manufacturing and contribute to U.S. economic growth by bringing more technological expertise and jobs to American soil,” said Zvi Lando, chief executive officer, SolarEdge. 

SolarEdge said it intends to produce DC optimized inverter systems for residential applications that meet the requirements of the domestic content bonus set forth by the IRA. The company said it expects to produce bonus-qualified residential inverters in Q4 2024 and qualified commercial scale inverters in 2025. 

The company said the U.S. manufacturing facilities will enable such SolarEdge systems to qualify for the full 35.6% of domestic content provided by a module-level power electronic (MLPE) system and support its customers’ ability to reach the required 40% domestic content threshold. 

“SolarEdge’s commitment to meeting the U.S. market through 100% domestic manufacturing is a strategic move aligned with our Inflation Reduction Act plan,” said Bertrand Vandewiele, general manager, SolarEdge North America. “This initiative is creating thousands of new jobs, building a robust workforce, bolstering the local economy and providing substantial economic benefits to the states and cities where we operate.”

Enphase Energy announced it is shipping U.S.-made IQ8P-3P microinverters designed for small-scale commercial installations. 

The Inflation Reduction Act incentivized many manufacturers, including Enphase Energy, to manufacture in the United States. In April the company reported it had shipped about 506,000 microinverters from its contract manufacturing facilities in the United States, making them eligible for the 45X production tax credit. 

“We are pleased to begin shipments of our IQ8 Commercial Microinverters from our contract manufacturing facility in Texas,” said Ron Swenson, senior vice president of operations at Enphase Energy. “Expanding our list of U.S.-supplied products has been a key objective, helping to ensure superior service with quicker delivery times for local customers in our top market.”

Each IQ8P-3P commercial microinverter supports up to 480 W of peak output power for three-phase commercial installations. The new microinverters are compatible with a wide range of solar panels including 54, 60, 66, 72, and 144-cell panels with full or split cells, supporting panels ranging 320 W to 640 W. Full specifications sheet and accessories can be found here.

The commercial Enphase Energy System includes the new IQ Gateway Commercial 2, which when connected to the internet enables over-the-air updates and to the Enphase App monitoring platform. The IQ Gateway and IQ Microinverters provide Fleet View for portfolio monitoring and management and Enphase Kiosk software that publicly displays system performance in real-time. The microinverters also feature Enphase Burst Mode technology that Enphase reports enables systems to start producing earlier and stop producing later in the day compared to other systems.

Tesla set a company record by deploying 9.4 GWh of energy storage in the second quarter of 2024, more than doubling its largest previous quarterly deployment. The 9.4 GWh value was 131% greater than the previous quarter, and 157% greater than the volume deployed in Q2’2023.

The company’s first two quarters of energy storage deployment in 2024, are equal to just over 91% of the entirety of the capacity deployed in 2023 – with the second quarter alone equal to almost 64% of 2023’s total deployment capacity.

The announcement was made in an unconventional section of Tesla’s end-of-quarter press release, which typically focuses on the number of vehicles manufactured. This quarter’s release highlighted the company’s significant strides in energy storage, showing its increasing importance to the bottom line.

From 2016 through the first quarter of 2024, Tesla’s energy business consistently contributed less than 10% to total revenue. The only exceptions were in 2017, where contributions peaked at 9.49%, and in the first quarter of 2024, at 9.41%, with all other periods seeing contributions remain below 7.25%. Based on estimates derived from vehicles sold and the substantial projected increase in energy storage revenue, we anticipate that energy revenue will account for 15% to 21% of Tesla’s overall revenue in upcoming periods, likely leaning towards the upper end of this range.

The capacity increase follows the initiation of operations at Tesla’s Megapack assembly facilities in Lathrop, California, in 2022, and in Shanghai, announced in 2023. Each facility is capable of delivering up to 40 GWh of Megapacks annually.

Unlike its regular updates on vehicle production, Tesla does not disclose the volume of energy storage products manufactured each quarter. Instead, it reports on the revenue from products it can recognize, which coincides with when the battery packs are activated. It is likely that several tens of GWh of capacity have been manufactured and delivered but remain unrecognized due to accounting practices.

The featured image in this article showcases the recently activated Sierra Estrella energy storage facility in Arizona.

In addition to its operational achievements, Tesla has relaunched its online energy storage pricing tool, now featuring significantly lower prices.

The company’s pricing for a 1.9 MW/3.9 MWh Megapack is currently listed at $1,039,290, which equates to $266/kWh. This price does not include installation or delivery and requires a $1,000 deposit to secure the order.

In April 2023, the price of the same hardware was $1,879,840, at a rate of $482/kWh. The price has decreased approximately 44% during the 14-month period.

This price reduction aligns with a general market trend that has seen energy storage cell costs in China drop from between $110 and $130/kWh to near $50/kWh.

According to the U.S. Energy information Administration, battery storage capacity in the country is on track to double in 2024, with developers planning to bring the total to over 30 GW by the end of the year. The vast majority of these new batteries are based on lithium-ion technology, which dominates the industry. However, lithium-ion batteries are in some ways a victim of their own success as perceptions of fire safety issues are growing along with installations.

John Zahurancik, president, Americas, of battery-maker Fluence Energy, said failures are going to happen with any equipment that has a significant installed base. The trick is to understand how and why failures happen and to make sure everybody affected knows what they are dealing with when they do.

“Some electrical transformers will fail just because you have millions and millions of units that are being shipped,” Zahurancik told pv magazine USA. “Not everything will be done perfectly, whether it’s manufacturing or installation or some random event like a lightning strike.”

Electric transformers have a large installed base, and while failures sometimes cause explosions or fires, it doesn’t mean the technology is inherently unsafe; it means there are a lot of them out there. As a result, fire and utility crews have become experts at handling and replacing transformers when they fail.

Zahurancik said the energy storage industry is working with standards organizations, first responders and professional associations to understand the characteristics of lithium-ion grid batteries in order to make them safer and more reliable.

“There has to be intelligence on the part of suppliers to make sure battery grid storage systems stay safe and effective throughout their lifespan,” he said. “There’s definitely design elements to managing safety and thermal events.”

Major suppliers such as Fluence have battery management systems incorporated into their grid storage projects. However, this is just a start, Zahurancik said, adding that to ensure operational safety:

• Companies need to have emergency response plans incorporated into every into every battery project;
• The projects themselves should be structured as multiple smaller battery storage units in order to reduce the spread of fires and make them easier to contain; and
• They should provide training to first responders at local fire departments where projects are to be deployed.

According to Zahurancik, expertise needs to flow readily between supplies, contractors, operators and first responders to prevent thermal events from making the news and warping public perceptions of lithium-ion battery safety. The company has representatives in fire safety standard bodies, such as the [National Fire Protection Association] NFPA 855 technical committee on energy storage installation.

“When things don’t go well, we have to talk about that in the spirit of, hey, everybody shouldn’t have to learn this lesson on their own,” he said. “We’re part of the American Clean Power Association and, one of its big pushes is to collect some of this information and propagate the best safety approach.”

Sometimes the best way to prevent fires is to start them and study the results. In May, Sungrow conducted a burn test of a 10 MWh installation to demonstrate the ability of its PowerTitan battery energy storage system to manage a thermal event without having it spread to other cabinets or require invention by emergency crews. The test was livestreamed to stakeholders and fire consultants.

“Too often, renewable energy skeptics raise fire safety concerns, even though batteries are overwhelmingly safe,” said the manager of energy storage engineering at Sungrow Americas, in a statement after the test. “These criticisms slow the adoption of such technologies.”

From pv magazine France

Ifrisol, a Tunisian solar module manufacturer, plans to commence sales in the United States by the end of 2024.

Laura Ramoul, Ifrisol’s marketing manager, told pv magazine France that the company has secured UL certification from Underwriters Laboratories for its products in the US and Canadian markets, ensuring they meet safety and quality standards.

To meet American supply chain requirements, the subsidiary of Zrouga Holding has adjusted its sourcing of PV cells, now including cells from unspecified Asian countries “outside China.” These are assembled into tunnel oxide passivated contact (TOPCon) and passivated emitter and rear cell (PERC) modules at Ifrisol’s 750 MW factory in the Kairouan industrial zone.

“We are increasing the plant’s capacity, which will soon rise to 1 GW per year,” said Ramoul.

The solar panels will be distributed in the United States through networks and directly to engineering, procurement, and construction (EPC) contractors, ensuring prices comparable to North American products.

Ifrisol is continuing its expansion in Europe, with a presence in Belgium, Switzerland, Spain, and the Scandinavian countries. In France, the company focuses on residential projects under 200 kW.

“We are studying market demand for PERC or TOPCon technology,” said Ramoul.

Ifrisol also plans to construct a warehouse in Senegal by early 2025 to serve the local market and neighboring countries. At the recent Intersolar Europe exhibition in Munich, Germany, Ifrisol unveiled a number of new products, including a TOPCon module in 430 W, 530 Wc, and 590 W variants.

From pv magazine Global

China-headquartered PV manufacturer Trina Solar said it has started mass production of its new full-black, n-type, tunnel oxide passivated contact (TOPCon) monocrystalline PV modules.

“The Vertex S+ full black module is specifically designed for PV residential settings, combining high performance with a sleek, modern appearance that seamlessly integrates with various architectural styles,” the company said. “With a full black aesthetic design, it measures 1762 mm x 1134 mm and weighs just 21 kg.”

According to the company, the product comes in six versions, each with varying peak power ratings and module efficiencies. The basic 430 W version has an efficiency of 21.5%, while the largest 455 W variant has an efficiency of 22.8%. The open-circuit voltage ranges from 51.4 V to 53.4 V, and short-circuit current spans from 10.59 A to 10.77 A.

The 144-cell panels operate between -40 C and 85 C (-40 F to 185 F). They come with a product warranty of up to 25 years and a power warranty of 30 years. Trina reports that the panels boast ultra-low degradation rates, with only 1% degradation in the first year and 0.4% annual degradation.

ESS Tech, listed on the New York Stock Exchange as “GWH”, announced it has secured a $50 million investment from the Export-Import Bank of The United States (EXIM).

The funds are expected to support the expansion of ESS production capacity at its Wilsonville, Oregon plant. The company develops long-duration energy storage iron flow batteries. The investment is expected to help ESS triple its manufacturing capacity at the Wilsonville plant.

“Our technology uses earth-abundant iron, salt and water to deliver environmentally safe solutions capable of providing up to 12 hours of flexible energy capacity for commercial and utility-scale energy storage applications,” said ESS Tech.

EXIM made the investment via its Make More in America Initiative, which makes available medium- and long-term loans, loan guarantees, and insurance to finance export-oriented domestic manufacturing projects.

ESS Tech is delivering iron flow energy storage systems to customers in Europe, Australia and Africa. The company manufactures 100% of its products in the United States, with a predominantly domestic supply chain that spans 29 states.

“Our partnership with EXIM underscores the critical role that American-made clean energy technology will play in the global clean energy transition,” said ESS chief executive officer Eric Dresselhuys. “ESS’s iron flow technology is already deployed in Australia and Europe and with this agreement, we are well positioned to meet the growing needs of our current and future global customers.” 

ESS battery systems are designed to operate for 25 years, while conventional batteries last about 7 to 10 years. The battery modules, electrolyte, plumbing, and other components may well last for decades longer with proper maintenance, said the company. The battery, for example, is expected to experience zero degradation over 20,000 cycles. The long duration energy storage (LDES) system can store and dispatch electricity for 12 hours or more.

According to the Department of Energy’s ‘Pathways to Commercial Liftoff: Long Duration Energy Storage’ report, the U.S. grid needs 225 to 460 GW of LDES capacity for power market application for a net zero economy by 2060. The global LDES market is estimated to be $50 billion per year and forecast to grow significantly with a cumulative investment of up to $3 trillion by 2040, according to the LDES Council and McKinsey & Co.

The latest supply chain report from Sinovoltaics, the Hong Kong-based technical compliance and quality assurance company, covers the North American manufacturing hub, tracking factory size, location, owner, current and planned capacity. It provides details on 95 factories producing PV modules, cells, wafers, ingots, polysilicon, and metallurgical-grade siliconin the region, up from 81 in the first quarter.

The Sinovoltaics Supply Chain Map (SSCM) – North America for Q2 2024 notes 42 GW of total module production capacity spread across Mexico, Canada, and the United States, which manufacturers plan to double to 84 GW in the coming 3 to 6 years. A Sinovoltaics spokesperson told pv magazine that the figures represent “nameplate capacity.”

The report presents data from publicly available sources, as well as Sinovoltaics contacts with manufacturers. “The report gives insights into the theoretical capacity if the factories are running at 100%,” a spokesperson from the company said. “Our data are based on the press releases that we’ve received from different manufacturers and different research, and marketing analysis documents that we’ve seen.”

There are ten more manufacturers included in the second quarter report than the previous one, a mixture of thin film, TOPCon, and perovskite tandem technology companies. The additions are Ascent Solar, Astronergy, Boway Alloy, Caelux, Great Lakes Solex, NanoPV, Prism Solar, Runergy, Solaria, and Ubiquity Solar.

The analysts noted constraints in the region’s supply chain at the cell and wafer nodes. Cell production is at 8 GW and growing to 55 GW in the coming 3 to 6 years, while wafer production is to grow from 3.2 GW to 24.5 G.

The Sinovoltaics team noted the CubicPV decision to halt silicon wafer production to focus on tandem perovskite technology and REC Silicon’s plant closure in Butte, Montana, observing that the market had not moved yet to fill the void.

Sinovoltaics has been tracking the development of PV manufacturing hubs and began publishing a series of free quarterly reports this year, mapping production in India, North America, Southeast Asia, and Europe

pv magazine interview: ‘Oversupply issues may continue in 2025’ As part of our Intersolar 2024 interview series, pv magazine spoke with Amy Fang, Senior PV analyst at InfoLink Consulting, about new solar factories coming online and decreasing solar modules prices. She says the downward trend may continue until the first half of next year, with prices reaching $0.07/W, and estimates global module demand for this year could reached between 470 GW and 500 GW.

Back contact solar beats mono PERC at lifetime energy generation A new analysis finds that back contact solar shows an average lifetime energy generation increase of 16.0% over mono PERC. The paper also says back contact had an average 9.7% shorter payback time and 10.7% lower LCOE across all modelled locations.

New York governor urged to double solar deployment goal Currently New York has a state target of 10 GW deployed by 2030. The state’s Solar Energy Industries Association has called for a new target of 20 GW of distributed solar by 2035.

Norsun plans to invest $620 million in a new 5 GW silicon ingot and solar wafer manufacturing facility on a 60-acre greenfield site in Tulsa, Oklahoma.

The Inflation Reduction Act (IRA) has motivated solar module manufacturers to build manufacturing facilities in the U.S; however, very few factories are planned for the production of ingots, wafers and cells. This shortage leaves U.S. solar module makers reliant on imports, mainly from China.

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.

“Our business plan has an ambitious timeline, so we knew we needed a partner who can work fast and efficiently to meet the critical need for American-made energy,” said NorSun CEO Erik Løkke-Øwre. “Oklahoma impressed us even before our selection journey – its robust clean energy, manufacturing ecosystem and workforce development programs were already on our radar, and its competitive business offerings and site acceleration options solidified our decision.”

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

“I’m proud to welcome Norsun to Oklahoma, and I’m thrilled that Oklahomans will benefit from hundreds of new jobs in the Tulsa area and a $620 million capital investment,” said Governor Kevin Stitt. “Our pro-growth policies, workforce development efforts, and ‘more of everything’ energy approach make us an incredible state to invest in, and I’m glad NorSun can be a part of it.”

A new white paper from research and consulting firm Exawatt examines and contrasts key module parameters across various technologies to assess the potential value these technologies may offer for residential and commercial applications. The white paper, authored by Molly Morgan and Alex Barrows of Exawatt, draws on analyses from the company’s Solar Technology and Cost Service.

The paper reveals that, in the modelling performed, back contact (xBC), heterojunction (HJT), and tunnel oxide passivated contact (TOPCon) technologies may exhibit meaningful improvements in lifetime energy generation compared to mono passivated emitter rear contact (PERC) technologies. Through detailed modelling exercises, the document evaluates how xBC, HJT, and TOPCon contribute to increased clean energy generation and potential financial savings depending on specific system parameters.

In both residential and commercial system modelling scenarios, the authors found that xBC stands out as the top performer, showing an average increase of 16.0% over mono PERC, while HJT and TOPCon offer generation gains of 11.4% and 8.2%, respectively.

Furthermore, the white paper delves into the profitability of residential and commercial installations through assessments of payback time and levelized cost of electricity (LCOE). Despite their premium pricing, xBC, HJT, and TOPCon technologies demonstrate enhanced profitability in both modelling scenarios in comparison to the previously mainstream mono PERC. Among these technologies, xBC emerges as the frontrunner, boasting an average 9.7% shorter payback time and 10.7% lower LCOE across all modelled locations.

While small cost reductions may still be achieved in the current PV industry, the white paper outlines that these are relatively minor in comparison to the potential efficiency gains offered by advanced technologies. High module efficiency is key to driving down system cost-per-watt, payback time, and LCOE, since it can drive down the per-watt costs of many key non-module costs such as labor and mounting.

The white paper underscores the importance for distributors, installers, and system owners to grasp the value proposition of high-performance technologies for informed decision-making on which technology has the greatest value for a specific application.

The authors conclude that as the industry continues to prioritize performance improvements over cost reductions, embracing high-performance PV technologies can pave the way for enhanced efficiency, cost savings, and sustainable energy solutions.

Origami Solar sets up regional fabrication of steel solar panel frames Partnerships with steel equipment producers in Ohio and two locations in Texas will enable Origami to have its steel solar module frames shipped from fabricator to module manufacturer in one to two days, the company says.

‘Module prices surprisingly keep going down’ As part of our Intersolar 2024 interview series, pv magazine spoke with Yana Hryshko, head of Solar Supply Chain Research for Wood Mackenzie, about overcapacity, declining panel prices and expected PV demand for the next years. She revealed that Chinese module procurement schemes are currently seeing unprecedented, “ridiculously” low bids, but she also noted that the $0.08/W threshold may now be difficult to exceed. Hryshko also expects many manufacturers to backpedal on previously announced capacity expansion plans and renegotiate module supply contracts.

Cultural considerations for international solar expansion Each region has a different way of doing things, whether it’s selecting sites, managing employees, or implementing manufacturing standards. Companies looking to expand into foreign markets need to be prepared to deal with these cultural differences, says Clean Energy Associates (CEA) Vice President Mark Hagedorn.

City of Detroit to install solar in mostly vacant neighborhoods Three Detroit neighborhoods were chosen as sites for solar facilities. The City plans to build 33 MW of solar to power its municipal buildings.

‘We expect solar panel prices to stabilize in the second half of the year’ At Intersolar Europe 2024, pv magazine spoke with Edurne Zoco, executive director, Clean Energy Technology at S&P Global Commodity Insights, about module price trends, increasing solar demand and PV manufacturing outside China. She claims panel prices may stabilize in the second half of this year or in early 2025 and says top seven Chinese manufacturers may even continue with capacity expansion plans. She also believes that, without further substantial incentives, Europe will not be able to recreate a domestic PV supply chain.

Origami Solar announced partnerships with three steel fabricators who will domestically produce steel solar module frames. The fabricators include with Welser Profile of Valley City, Ohio; Priefert, of Mt. Pleasant, Texas; and Unimacts of Houston, Texas. Origami expects to be able to ship steel frames to customers in the first quarter of 2025, and by producing regionally says that frames will get from the fabricator to the module manufacturer in one to two days.

“America has one of the world’s strongest steel industries” said Origami Solar CEO Gregg Patterson. “We have the energy efficient steel mills and the world-class fabricators that can produce every solar frame America will ever need.”

Origami Solar, founded in 2019 and based in Bend, Oregon, is a pv magazine 2023 award winner for manufacturing. The company produces patented, steel solar module frames that are said to lower cost and improve module performance. The company reports that the frames are made of “green” recycled steel, thereby reducing greenhouse gases by up to 93%, representing a reduction of 80 kg per module or 200 metric tons per MW.

A recent report by Wood Mackenzie and Origami Solar notes that while the U.S. is working toward building up its domestic module manufacturing, thanks for the IRA, a less well-known problem is U.S. dependence on aluminum module frames. The majority of these are currently imported from East and Southeast Asia, and the report says that they are all made from carbon-intensive aluminum.

Origami sees an opportunity to supply module manufacturers in the U.S. market who are switching from imported aluminum frames to domestically made steel frames. Its use of recycled steel from suppliers in the U.S. and Europe in its frames give it a competitive edge when it comes to greenhouse gas scoring as assessed by Boundless Impact

Patterson points out that by having regional fabrication centers in the U.S., customers will avoid “shipping issues, labor strife, or impoundments delaying the arrival of the frames they need.” He added that by procuring domestically produced steel frames customers won’t have the worry of “geopolitical tensions” or “ever-increasing tariffs.” In light of recent news about fragile solar panels, he noted that steel frames may alleviate the risk of frames failing to support ever-larger solar panels.

Switching to domestically produced products across the solar supply chain has the further benefit of supporting good-paying jobs.

“Thanks to our partnership with Origami, we were able to expand our investments in the solar industry, keep our Benton, Arkansas facility open, keep our current employees hard at work and expand to up to 70 additional skilled workers over the next three years,” said Rocky Christenberry, Priefert’s executive vice president

Meyer Burger’s new plant in Goodyear in Arizona passed the factory audit according to UL test standards without any deviations, and production can begin.

The solar cells required for module production have been delivered from the German site in Thalheim to the U.S. plant for some time now. This will continue to be the case in the future to ensure the ramp-up in the USA, Meyer Burger added.

In addition to the module factory, Meyer Burger also plans to build a cell factory in Colorado. It is not yet entirely clear when this will be able to start production. This depends on the conclusion of the 45X financing. The due diligence of a major U.S. bank on monetization in accordance with Article 45X of the Inflation Reduction Act (IRA) has been completed and negotiations on the loan agreements are currently underway.

Meyer Burger says it is aiming to complete the deal and make the payment by the middle of the third quarter. At this time, the payment of export financing by a German bank for the construction of photovoltaic production in the U.S. is also expected. The photovoltaic company has also submitted the final application for the loan from the U.S. Department of Energy to finance the cell factory. This is currently still being reviewed, says Meyer Burger.

In addition, a commercial agreement has already been negotiated with a U.S. industrial and technology group and a term sheet for a possible investment in Meyer Burger has been exchanged. This strategic cooperation would enable Meyer Burger to manufacture solar modules in the U.S. with an ever-increasing proportion of domestic components.

Meyer Burger has already signed several contracts with EPC companies and energy suppliers for the purchase of its solar modules manufactured in the U.S.. Now another purchase contract for up to 600 megawatts per year has been added with a large energy company from the U.S.. Delivery has been agreed for three years from 2026 with an extension option for two years. The agreement is to take effect when the financing of the solar cell plant in Colorado Springs is completed, Meyer Burger said.

Meyer Burger shut down its module plant in Freiberg, Saxony , in April after there was no agreement within the federal government on resilience measures for German and European photovoltaic manufacturers .

Top solar panel brands in reliability, quality, and performance Solar modules are evaluated in the Renewable Energy Test Center annual PV Module Index.

pv magazine interview: ‘In the next year, some of these guys are going to be bankrupt’ At Intersolar in Munich, pv magazine spoke with Jenny Chase, solar analyst at BloombergNEF, about the incredibly low polysilicon prices, massive overcapacity, and increasing consolidation. According to Chase, this year there will be enough polysilicon capacity to produce 1.1 TW of solar modules, but global module demand is expected to reach around 585 GW. 

The Renewable Energy Test Center (RETC) released its 2024 PV Module Index report, evaluating the reliability, quality, and performance of solar panels.

Solar modules are put through a variety of accelerated stress tests to evaluate these parameters. Through comparative test results, project stakeholders can select products best suited for a particular environment, location, or portfolio.

To identify the best of the best, RETC reviewed and ranked the overall data distributions across three disciplines: quality, performance, and reliability. Find the overall top performers at the end of this report.

Reliability

Backsheet ultraviolet durability

Top performers: JA Solar, Longi Solar, SolarSpace

Backsheet ultraviolet durability (BUDT) incorporates a durability testing sequence to probe glass-on-backsheet PV module designs for vulnerabilities to UV exposure and prevent backsheet-related failures. This BUDT sequence starts with 1,000 hours of damp heat exposure to weaken polymeric bonds.

Highlighted top performers experience no backsheet cracking in the test.

Damp heat test

Top performers: Astronergy, ES Foundry, Longi Solar, Runergy, and Trina Solar

The RETC thresher test includes a damp heat test that exposes modules for 2,000 hours, double the amount required for product certification. The test evaluates a module’s ability to withstand prolonged exposure to humid, high-temperature environments. Taking place inside an environmental chamber, the test exposes modules to a controlled temperature of 85 C (185 F) and a relative humidity of 85% for a set amount of time.

RETC highlighted performers that experienced less than 2% degradation after this exposure.

Hail durability

Top performers: JA Solar, Longi Solar

RETC’s hail durability test takes UL and IEC standards testing a step further, exposing solar modules to higher kinetic impact to reflect the risk posed by hail over a 25 or 30-year operating life. In addition to ballistic impact testing, RETC runs thermal cycle and hot-spot tests to reveal potential long-term module degradation.

The top performers in this category withstood an effective kinetic energy of 20 Joules or more. These modules effectively demonstrated resistance to a 45 mm (1.8 in.) iceball traveling at a terminal velocity of 30.7 m/s (68.7 mph).

Potential induced degradation (PID) 

Top performers: Astronergy, ES Foundry, GEP VN, Gstar, JA Solar, Longi Solar, Qcells, REC Solar, Runergy, SEG Solar, Silfab Solar, SolarSpace, Talesun, Trina Solar, VSUN Solar, and Yingli Solar

Potential induced degradation (PID) resistance tests rack-mounted modules in an environmental chamber, which controls temperature and humidity and exposes them to a voltage bias of several hundred volts with respect to the mounting structure for 192 hours (PID192 exposure). PID testing characterizes a module’s ability to withstand degradation due to voltage and current leakage resulting from ion mobility between the semiconductor and other elements in module packaging.

RETC required that PV module models withstand PID192 exposure with less than 2% degradation in maximum power. At the other end of the spectrum, it considered maximum power degradation greater than or equal to 5% a red-flag result.

Static and dynamic mechanical load test

Top performers: Aptos Solar, Astronergy, ES Foundry, Gstar, JA Solar, Longi Solar, Runergy, Silfab Solar, SolarSpace, Trina Solar, and Yingli Solar

This test exposes modules to 1,000 cycles of +1,000 pascal and –1,000 pascal loads at a frequency of three to seven cycles per minute. Measurements were taken after this stress test rate electrical performance.

This year, RETC required that PV module models withstand SDML exposure with less than 2.5% degradation in maximum power. It considered maximum power degradation greater than or equal to 5% to be a red-flag result. In this testing category, it notes that 68% of samples qualified as high achievers whereas 7% returned red-flag results.

Thermal cycling

Top performers: Aptos Solar, Astronergy, ES Foundry, Gstar, JA Solar, Longi Solar, Qcells, Runergy, SolarSpace, Trina Solar, and Yingli Solar

The thermal cycle test calls for cycling modules in an environmental chamber between two temperature extremes—85 C (185 F) on the high end and –40 C (–40F)  on the low end. The RETC test runs 600 cycles, three times as much as the 200 required for certification.

About 67% of modules in this test achieved high performer status of less than 2% power loss, while 9% of tested brands had power losses of 5% or more.

Ultraviolet induced degradation (UVID)

Top performers: Trina Solar and VSUN Solar

UVID tests characterize a PV module’s ability to withstand ultraviolet induced degradation. This optional testing sequence exposes test samples to 220 kWh/m2 of UV exposure (UV220), nearly 15 times the UV exposure required for product certification.

Top performers withstand UV220 exposure with less than 2% degradation in maximum power. Red flag modules that degraded more than 5% represented 40% of brands tested.

“Alarmingly, we observed double-digit power loss in some mass-produced, commercially available PV modules, indicating that these products could degrade 10%–16% in the first three years of in-field operation,” said RETC.

Performance

Module efficiency

Top performers: Astronergy, Mission Solar, Qcells, REC Solar, and Silfab Solar

Module conversion efficiency is determined by dividing a product’s nameplate maximum power rating under standard test conditions by its total aperture area.

RETC has recognized manufacturers of PV module models with conversion efficiencies greater than 21% as test category high achievers. About 56% of tested modules were listed as high performers.

Incidence angle modifier

Top performers: Dehui Solar, ES Foundry, JA Solar, JinkoSolar, Longi Solar, Meyer Burger, Qcells, Runergy, Silfab Solar, and SolarSpace

Incidence angle modifier (IAM) is a performance characteristic that accounts for changes in PV module output based on changing sun angles relative to the plane of the array. To characterize IAM, RETC conducts electrical characterization tests at different incidence angles, ranging from 0° to 90°.

Manufacturers of PV module models with an IAM greater than 88% at a 70° angle of incidence were listed as test category high achievers.

LeTID resistance

Top performers: Astronergy, Gstar, JinkoSolar, Longi Solar, Runergy, SEG Solar, Silfab Solar, SolarSpace, Talesun, Trina Solar, VSUN Solar, Waaree, Yingli Solar

Relatively new cell technologies may experience long-term degradation associated with light exposure and elevated temperatures. This phenomenon, called light- and elevated temperature-induced degradation (LeTID), is tested with a protocol of light soaking, followed by 75 C (167 F) temperature exposure for two 162-hour cycles to identify significant degradation (>5%). Subsequently, test samples are subject to 500 hours of 75 C temperature exposure followed by two additional 162-hour cycles.

Highlighted top performers demonstrated products that had less than 0.5% power loss after 486 hours of exposure.

LID resistance

Top performers: Astronergy, GEP VN, Gstar, JA Solar, JinkoSolar, Longi Solar, Meyer Burger, Qcells, Runergy, SEG Solar, Silfab Solar, SolarSpace, Talesun, Trina Solar, VSUN Solar, Waaree, and Yingli Solar

Light-induced degradation (LID), or power losses from sunlight exposure, affects some PV cell types but not others. PV modules exposed to LID losses rapidly lose performance over the first few hours or days of operation before stabilizing. RETC notes LID resistance is highly correlated with cell type.

RETC required that PV module models withstand the LID sequence with less than or equal to 0.5% degradation in maximum power.

Module efficiency

Top performers: Auxin Solar, JA Solar, Longi Solar, Meyer Burger, Mission Solar, Qcells, REC Solar, Silfab Solar, Trina Solar, Yingli Solar

Module efficiency, or the percentage of incident solar energy converted to electrical energy, is a well-known and key metric for solar performance. It is highly correlated with cell technology and module design.

The top 14 highest scoring modules scored efficiencies of 20% or more. An n-type TOPCon cell scored the highest at 25.8% efficiency, followed by a monocrystalline silicon module with heterojunction technology, recording a 22.4% efficiency.

Summit Ridge Energy expanded its partnership with Qcells with an agreement to purchase 800 MW of solar panels.

The agreement builds on an existing 1.2 GW relationship between Qcells and Summit Ridge, announced in April of 2023 by Vice President Kamala Harris. At the time the 1.2 GW order was the largest equipment purchase in history for the community solar market.

By increasing the total commitment to 2 GW, Summit Ridge reports it will develop more than 100 additional community solar projects across the country using U.S.-made solar.

Last year Qcells announced what was then the largest investment in U.S. solar manufacturing history, investing more than $2.5  billion to build a complete solar supply chain in the United States. This made the Korean company, a subsidiary of Hanwha Solutions, the first company to establish a fully-integrated silicon-based solar supply chain in the U.S. When complete, Qcells solar panels — from polysilicon to the finished panel — will be entirely made in the U.S.

Both the build-out of Qcells U.S. manufacturing footprint and the growth of Summit Ridge Energy are incentivized by the Inflation Reduction Act (IRA). The includes tax incentives for domestic energy production as well as manufacturing. Many of Summit Ridge’s solar projects also qualify for IRA tax credits that will provide thousands of low-income households with greater access to clean energy savings.

“We are excited to expand our partnership with Qcells, which enables Summit Ridge to deliver on our promise of giving more Americans the opportunity to power their homes and businesses with locally generated clean energy,” said Brian Dunn, chief operating officer of Summit Ridge Energy. “Through our Qcells partnership, we are able to support domestic manufacturing and job creation, while simultaneously bringing low-cost clean energy to communities that have historically been left out of the clean energy transition.”

Summit Ridge’s planned fleet of community solar farms are expected to generate enough clean energy to power an estimated 200,000 homes and businesses. Since launching in 2017, the company reports that it has deployed over $2.6 billion into clean energy assets and controls a development pipeline of more than 3 GW that will provide solar power to homes and businesses nationwide.

“Expanding this relationship with Summit Ridge Energy means more communities will have access to the most affordable energy resource in the world,” said Justin Lee, CEO of Qcells. “This partnership not only supports the domestic manufacturing industry and thousands of jobs in solar, but it also ensures more people – especially those who have historically been left out – benefit from everything the clean energy economy has to offer.”

The majority of the solar panels purchased by Summit Ridge will be produced in Qcells’ new U.S. manufacturing facility located in Georgia. Additionally, Qcells will continue to provide Summit Ridge with battery storage and software solutions under separate procurement agreements.
