Abstract

A composite laminate specifically adapted to protect the light incident surface of a photovoltaic module from cuts which could create a short circuit includes a plurality of stacked layer pairs. The first layer of each pair is a glass fiber material and the second layer is a thermoplastic. The layers are disposed in a mutually interpenetrating relationship and topped with a thin transparent protective layer, such as a layer of a fluoropolymer. this combination of layer pairs has been demonstrated to provide sufficient protection to meet Underwriters Laboratories specifications (UL 1703 Section 23. Cut Test) for flat plate photovoltaic modules and panels.
