With the increasing frequency of anomalous meteorological events or strong squalls in the Spanish region during certain times of the year, one of the questions most anxiously asked by clients is: "What will happen to my new solar panels if large hailstones fall?".
It makes logical sense to imagine an outdoor panel with a smooth glass front must be fragile against a direct impact from the clouds, but the industrial reality has engineered a completely armored environment.
Certifications against Impacts
During European Union regulatory tests under CE quality marking, the operational cells we use undergo complex impact tests. Simulation projectiles (solid spheres with a high relative weight) are launched at very high speeds to mimic hailstorms exceeding 80 km/h (50 mph), aimed directly at the core of the front glass.
Today, the use of safety-grade tempered photovoltaic glass ensures that no sheet shatters into sharp pieces during a normal weather event. Before anything else, we always advise how you can integrate, with a tiny fee added to your standard home insurance, full coverage for the installed system, protecting yourself in the long term.
