How durable are the Solar Electric Modules?

Solar Electric Modules are very durable, and constructed with strong aluminum frames and high strength tempered glass designed to withstand hailstorms. A standard test procedure (IEC 61215) for the glass used is to drop a steel ball with one inch diameter from 3 feet onto the glass, which has to withstand the impact. That is the power of a golf ball hit by a professional from 120 feet distance.
