Strong winds and home solar panels: installation best practices
Solar panels intended for use on homes and businesses are remarkably strong and designed to withstand many different kinds of abuse from the weather, including rain, hail, and severe wind. In North America, test standards require that solar panels must be able to support 5,400 Pascals (Pa) of force on the front of the panel. That works out to 0.783 pounds per square inch. An average sized solar panel is about 2,500 square inches, which means that one panel can support about 2,000 pounds!
