Soltec introduces hail defense algorithm for enhanced solar module protection

  • Innovative technology mitigates hail damage risk across photovoltaic installations
  • The whitepaper highlights the vulnerabilities of solar modules to hail damage, emphasizing the unpredictable and destructive nature of hailstorms, with 2021 losses in the United States alone exceeding $1 billion
  • Soltec’s Hail Algorithm ensures a swift response minimizing module exposure to hail impacts and offering unparalleled protection for solar installations

Miami – November 22, 2023. Soltec, a global leader in solar tracking solutions, has unveiled a groundbreaking hail defense algorithm designed to protect photovoltaic modules from the destructive impact of hailstorms. In a comprehensive whitepaper released today, Soltec addresses the increasing threat posed by hail, a weather phenomenon notorious for causing extensive damage to solar installations globally.

Hailstorms, with their unpredictable nature and destructive potential, pose a significant challenge to solar power infrastructure. In 2021 alone, hail-related losses in the United States exceeded $1 billion. Soltec's whitepaper explores the vulnerabilities of solar modules to hail damage, emphasizing the urgent need for innovative solutions.

Soltec's research reveals that the risk of module damage due to hail impact is most often due to the direct and perpendicular strike of hailstones to the front glass of the module. The whitepaper introduces a novel approach, demonstrating that adjusting the tilt angle of solar panels during a hail event to a significantly higher angle will reduce the force absorbed by the glass of the module, thereby minimizing the risk of damage.

At the core of Soltec's solution lies its Hail Algorithm, a sophisticated system that combines prediction and detection to safeguard solar installations. The algorithm, equipped with dedicated hail detection sensors, ensures a rapid response to incoming hailstorms. This real-time detection, coupled with a swift adjustment of the solar tracker position, minimizes module exposure to hail impacts, providing an unparalleled level of protection.

How Does It Work?

By analyzing various tilt angles and hailstorm parameters, Soltec demonstrates the effectiveness of its hail stow position. Photovoltaic modules in the designated hail stow position have a lower exposed surface area that hailstones can strike when falling from the sky, which results in fewer hailstone impacts. Moreover, the steeper angle of the panel reduces the impact forces absorbed by the glass, which leaves is less subject to damage. The whitepaper provides detailed tables showcasing the percentage of exposed module surface for different tilt angles and hail directions, highlighting the substantial reduction in risk.

The whitepaper concludes with a call to action for solar tracking plants in hail-prone areas to adopt Soltec's innovative hail stow algorithm. Catastrophic module damage due to hail impact can result in substantial economic losses, making early detection and preventive measures crucial for the sustainability of solar power installations.
