View the Complete Application at the US Patent & Trademark Office
A PV module including a PV device and a frame. The PV device has a PV laminate maintaining a plurality of PV cells at a front face. The PV cells are arranged in rows, including a first row adjacent an edge of the PV laminate. Adjacent ones of the PV cells of the first row are separated by a column spacing. The frame is assembled to the PV laminate, and includes a frame member having a ledge and a plurality of spaced fingers that are connected to, and spaced from, the ledge. The PV laminate is mounted between the ledge and the fingers, with one of the fingers being aligned with one of the column spacings. The PV module facilitates liquid drainage between the spaced fingers. Further, the fingers minimize shading effects presented by the frame member, thereby enhancing a GCR of the PV module.
