MOISTURE INGRESS RESISTANT PHOTOVOLTAIC MODULE

摘要

One embodiment of the present invention provides a photovoltaic (PV) module. The PV module includes a front-side glass cover facing sunlight, a plurality of interconnected PV cells situated below the glass cover, a plurality of bussing wires electrically coupled to the PV cells, and a back-sheet situated below the PV cells. The back-sheet comprises a metal layer sandwiched between a top and a bottom insulation layers. The back-sheet comprises a cut slot to facilitate the bussing wires to thread through the cut slot to reach a junction box situated below the back-sheet. The PV module further comprises one or more insulation layers inserted between the bussing wires and sidewalls of the cut slot in the back-sheet. The insulation layers are configured to insulate the bussing wires to the metal layer in the back-sheet.
