US Patent 7557291 Photovoltaic module for roofs

A photovoltaic module generates electrical power when installed on a roof. The module is constructed as a laminated sandwich having a transparent protective upper layer adhered to a photovoltaic layer. The photovoltaic layer is adhered to a rigid layer formed from a composite panel of fiber reinforced plastic and a metallic layer. The laminated sandwich has a plastic-clad aluminum frame around the perimeter. The laminated sandwich is coated with a moisture resisting coating. The laminated panel has a layer of double stick tape on the bottom to adhere the panel to the surface of a roof.
