Description

Technical Field

[0001] The utility model belongs to the technical field of photovoltaic component manufacturing, and in particular relates to a frame structure of a photovoltaic component. Background Art

[0002] Solar photovoltaic power generation is a technology that uses the photovoltaic effect at the interface of semiconductors to directly convert light energy into electrical energy. The cells in a photovoltaic module are connected in series and then encapsulated and protected to form a large-area solar cell laminate. Adding a frame to the laminate effectively protects it from environmental damage and facilitates the installation of the photovoltaic module. Existing frames include aluminum alloy frames and resin fiberglass frames, and installation methods include block mounting and screw mounting. For example, screw mounting of resin fiberglass frames poses the risk of damage to the screw holes. This potential risk makes the use of resin fiberglass frames in photovoltaic systems relatively cautious. Eliminating these hidden risks has become a pressing issue for composite frames.
