Description

Technical Field

[0001] This utility model relates to the field of photovoltaic technology, specifically to a photovoltaic frame mounting component. Background Technology

[0002] With the global trend of energy structure transitioning towards clean energy, photovoltaic (PV) modules, as the core component of solar power generation systems, directly determine the economics of the entire system through their power generation efficiency and lifespan. As a key structure of PV modules, the frame not only needs to fix and protect the laminated components (composed of glass, solar cells, backsheets, etc.), but also needs to withstand the long-term test of complex outdoor environments (such as wind, rain, and temperature differences). Therefore, the structural design of the frame is crucial to the overall performance of the PV module.

[0003] Existing photovoltaic frame mounting structures have at least the following technical problems:

[0004] 1. Dust accumulation on the frame: Existing photovoltaic frames generally adopt a structural design where the short side frame is "higher than the top surface of the laminate". This design creates a stepped structure between the short side frame and the top surface of the laminate. Dust, fallen leaves, sand and other impurities in the outdoor environment easily accumulate at this structure, making cleaning inconvenient.

[0005] 2. The short side frame blocks the solar cells for a long time, affecting the power generation efficiency: The edge of the laminate of photovoltaic modules is usually distributed with edge solar cells. Because the existing short side frame is higher than the top surface of the laminate, its inner wall will block part of the light-receiving area of ​​the edge solar cells for a long time, thus affecting the power generation.

[0006] 3. Low frame assembly efficiency: The existing photovoltaic frame uses multiple bolts to connect the short and long sides. The connection requires accurate alignment of the holes and tightening of multiple bolts, which is inconvenient and affects the assembly efficiency. Utility Model Content

The plug-in connection method is convenient for installation and can effectively improve assembly efficiency.

[0042] After assembly, both the short side frame 11 and the first plug-in body are flush with the top surface of the laminate 14. Thus, in actual use, the frame assembly 1 is flush with the front and back direction, and the dust on it can be removed by natural wind and rain or regular washing, making it less prone to accumulation. This not only effectively reduces maintenance costs, but also ensures that the short side frame 11 does not block the light-receiving area of ​​the battery cells, thereby guaranteeing power generation and improving power generation efficiency.

The second upper limit edge 121, the second side limit edge 122 and the second lower limit edge 123 form an inner open second mounting groove. The second mounting groove wraps around the long side of the laminate 14, and the laminate 14 is firmly installed.

[0060] The top surface of the second upper limit edge 121 is provided with a guide slope 124. The height of the guide slope 124 gradually decreases towards the laminate 14.
