Technical Field

[0001] The utility model relates to the technical field of photovoltaic power generation panels, in particular to a photovoltaic module wiring device for photovoltaic power generation. Background Technique

[0002] Photovoltaic power generation is a technology that directly converts light energy into electrical energy using the photovoltaic effect at the semiconductor interface. It mainly consists of three major parts: solar panels, controllers, and inverters. The main components are composed of electronic components. Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as power controllers to form a photovoltaic power generation device.

[0003] Currently, most of the connections between photovoltaic power generation panels are made in an exposed manner, or fixed using tape or straps. Although this fixing method is convenient, during long-term use, the tape may become loose, and the straps may break and fall off due to corrosion and aging. Therefore, we urgently need a photovoltaic module wiring device for photovoltaic power generation to solve the above problems. Summary of the Utility Model
