How large a hailstorm can damage Solar PV Panels ?

In recent years, with the rapid development of the solar energy industry, concerns about the protection of PV panels have grown, particularly when facing natural disasters such as hail. So, how large do hailstones need to be to damage a PV system? And once they exceed a critical threshold, does the damage become significant?

According to experts, hailstones with a diameter less than 2.5 centimeters will not cause damage to PV panels. However, as the diameter of hailstones increases, the risk of damage to solar panels also escalates. Hailstones exceeding 3 centimeters in diameter may result in varying degrees of damage to PV panels. To safeguard the safety of PV panels, some manufacturers implement special protective measures, such as coating glass panels with unique coatings to prevent hail impact or adding protective layers between the base and the PV panels. Additionally, some manufacturers offer insurance services to protect PV panels from various natural disasters.

Nevertheless, even though PV panels have a certain resistance to impact, the potential threat posed by hailstones cannot be entirely overlooked. Therefore, when purchasing solar energy equipment, it is essential to select products with protective measures and communicate with manufacturers for more details. Regular maintenance and inspections are also crucial means of protecting PV panels. By choosing reliable-quality PV panels and implementing appropriate protective measures, we can effectively safeguard these devices, ensuring they continue to function steadily and contribute to the development of clean energy.
