COMPLETE DETAILS OF SOLAR PV PANEL This article gives compete information, defines and explains the pertinent mechanical technical data. Area Simply width times length, the area of a module is useful for checking power density (watts per ft.2). The total module area can be used along with site-specific data to calculate wind uplift forces and thus lag bolt requirements, or to calculate weight loading on a structure. Thickness The frame thickness determines what rack components to use, like slip-in racks, or the required size of end and inter module clips. Typically, thicker frames result in sturdier, although heavier, modules. Weight Most permitting authorities will ask for basic structural engineering data for roof-mounted PV arrays, and there will be a limit to the weight that can be added to a roof structure. Module weight, rack weight, and engineering data will restrict the quantity of PV modules that can be installed. Crystalline, glazed modules with plastic back
