first, for wind pressure loading we will use the simple cheat formular of around: pounds/sqft = 0.00256*(mph*mph) so 90mph wind results in a force of 21lbs/sqft (its double for a cat5 hurricane hehe). For a 4''x8'' solar panel you have 32sqft * 21 = 672lbs force per panel.
Solar Photovoltaic (PV) Modules A unit made up of the solar cells that convert solar radiation to electricity. Typically, solar modules have a glass top sheet above the solar cells. The glass sheet is held in place with a metal (usually aluminum) frame around the outside of the module. Storm events can crack or break the glass on modules or detach
