What’s the average size of hail that damages solar panels?

Hail Damage to Solar Panels

Hail damage to solar panels can be a significant concern for off-grid and grid-tie systems. The impact of hail on solar panels depends on various factors, including the size and speed of the hailstones, the angle of incidence, and the type of solar panel material used.

Assessing Hail Damage Risk

To assess the risk of hail damage to solar panels, consider the location and local weather patterns. Areas prone to thunderstorms, heavy rain, and strong winds are more likely to experience hail. In the United States, for example, states like Texas, Oklahoma, and Kansas are considered high-risk areas for hail damage. If you live in an area with a history of hail storms, consider installing impact-resistant solar panels or investing in a hail protection system.

Measuring Hail Damage

When assessing hail damage to solar panels, look for signs of impact, such as dents, cracks, or broken glass. Measure the diameter of the hailstones to determine the severity of the impact. Hailstones larger than 1 inch (2.5 cm) in diameter can cause significant damage to solar panels, while smaller hailstones may only cause minor damage. To mitigate hail damage, consider installing a hail shield or using solar panels with a built-in hail protection system. Regular maintenance and inspections can also help identify potential issues before they become major problems.
