Technical Field

The utility model relates to the technical field of solar power generation, in particular to a general grounding structure of a solar photovoltaic panel.

Background

Solar photovoltaic panels are generally required to be grounded when installed. Because the frame of the solar photovoltaic panel mostly adopts an aluminum frame, the surface of the aluminum frame is provided with an oxidation layer or a coating layer, and the oxidation layer or the coating layer is not conductive, the aluminum frame may be poorly grounded. Therefore, when a photovoltaic system with a grounding requirement is installed, the oxide layer or the coating layer needs to be damaged to ensure that the solar photovoltaic panel is effectively grounded, but the existing solar photovoltaic panel has diversity, for example: the length is wide high, and the manifold difference such as thickness also has the variety, can not all unify in the scheme of solving ground connection, and some are through the installation earth connection, and some are the oxidation film that punctures the subassembly through the bottom etc. had so both increased the installation degree of difficulty and cost, and later stage fortune dimension is also troublesome.
