Abstract
Methods and devices are provided for improved roofing devices. In one embodiment of the present invention, a photovoltaic roofing assembly is provided that comprises of a roofing membrane and a plurality of photovoltaic cells supported by the roofing membrane. The photovoltaic cells may be lightweight, flexible cells formed on a lightweight foil and disposed as a layer on top of the roofing membrane. The roofing assembly may include at least one flexible encapsulant film that protects the plurality of photovoltaic cells from environmental exposure damage, wherein the encapsulant film is formed using a non-vacuum process. Optionally, the process may be a lamination process. In other embodiments, the process is a non-vacuum, non-lamination process. The resulting roofing membrane and the photovoltaic cells are constructed to be rolled up in lengths suitable for being transported to a building site for unrolling and being affixed to a roof structure.
