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.
