Description

Technical Field

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

[0002] Photovoltaic modules are generally composed of frames, glass, packaging films, solar cells, back panels and junction boxes. The function of the frames is to fix and seal the solar cell modules and increase the strength of the modules. It has the advantages of extending the service life of solar panel modules and facilitating transportation and installation.

[0003] Existing photovoltaic modules are often installed at a low angle, such as on a color-coated steel roof or sun room. Due to the height difference between the frame and the module surface, dust and dirt will accumulate at the lower edge of the frame, affecting the power generation of the module.

[0004] To solve this problem, some new photovoltaic modules with short frames have emerged. Figure 1 As shown, this frame adopts a topless design, so that there is no height difference between the frame and the surface of the component, so that dust will not accumulate. At the same time, a slope 21 is set on the top of the L-shaped frame 2, so that rainwater can be easily retained. The dust on the surface of the photovoltaic component can be washed clean in natural precipitation, which can greatly reduce the adverse effects of dust accumulation on the photovoltaic component and improve the reliability and weather resistance of the photovoltaic component. However, the photovoltaic component frame of this structure can only adapt to the use scenario of a single row of photovoltaic components arranged side by side, and cannot be applied to the use scenario of multiple photovoltaic components connected front and back, because after the photovoltaic components connected front and back are spliced, due to the existence of the slope, rainwater is easy to flow down between the two adjacent frames, and dust is also accumulated between the two adjacent frames.

The inclined surface 31 can abut against the slope 21, and the horizontal surface 32 is the upper side surface of the first rubber strip 3. After the module is installed on the L-shaped frame 2, the horizontal surface 32 is flush with the surface of the module.

[0028] Through the above settings, in actual use, if the photovoltaic modules are used in a single row, Figure 8 As shown, the first adhesive strip 3 is not needed. At this time, the surface of the module is flush with the top of the L-shaped frame 2, so that rainwater can naturally wash away dust and the like, so that dust will not accumulate. At the same time, the slope 21 is also conducive to rainwater carrying dust and the like to flow down. If the photovoltaic modules are arranged front and back, Figure 2 - Figure 7 As shown, the front and rear photovoltaic module frames are abutted, and the first rubber strip 3 is installed at this time. The first rubber strips 3 on the two photovoltaic module frames abut each other to form a plane, so that rainwater and impurities will not remain in the groove formed by the two slopes 21, reducing the accumulation of impurities. At the same time, the two first rubber strips 3 abut each other also have a sealing effect, preventing rainwater from entering between the two photovoltaic module frames, thereby being able to adapt to different usage scenarios.
