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. Real-world performance exceeds expectations:. . 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 country, and most solar panels can withstand light-to-moderate impact. Even hail is usually not enough to damage your solar panels.
