Methods and devices are provided for improved large-scale solar installations. In one embodiment, a photovoltaic module is provided comprising a module front layer comprising a glass plate, a module back layer comprising an electrically conductive foil, and a plurality of solar cells arranged to be protected by the front layer and the back layer. In some embodiments, the module back layer is aluminum foil. The module back layer may have an externally exposed surface. The module back layer may be electrically grounded. An electrically insulating pottant material may be used with the solar cells to separate them from the module back layer. This allows for a high voltage withstand between the cells and the outer surface of the back layer.
