The short answer is yes, hail can damage solar panels, but modern photovoltaic systems are engineered to withstand most hailstorms with remarkable resilience. In areas that have experienced very large hail (greater than 1 ¾" or 44 mm diameter), however, hail has caused significant damage to PV modules. Some measures can be taken to limit damage to. . Glass thickness is the critical protection factor: Research confirms that 4mm glass panels significantly outperform the standard 3. 2mm thickness, with thicker glass successfully reducing or nullifying hail damage that destroys thinner alternatives. Solar panels are designed to withstand harsh weather conditions, like high winds and heavy rain – but what about frozen balls of hail falling from the sky? Luckily, severe hail storms aren't super common around the. . When golf ball-sized hail started hammering Texas last spring, solar panels across the state faced their ultimate test. Although hail is a common concern, it is generally not damaging. Hail damage is most likely in certain parts of the U.
