Are the solar panels fragile? Can they withstand wind and hail?
No. The panels are supported by a engineer-designed mounting system that has been tested to withstand high winds and can work on almost every type of roofing material. The panels are made of tempered glass (the same as a modern car windshield), and are impact tested to withstand snow, ice, wind and moderate hail storms. For example, one manufacturers modules are tested to withstand one inch (2.5 cm) hailstones at 50 mph (80.5 kph). Panels generally have a 20 or 25-year warranty and are even installed in extreme Arctic and Antarctic locations.
