[0025] The present invention will be further described below in conjunction with the accompanying drawings.

[0026] The invention discloses an insert block for photovoltaic assembly reflective gain and a photovoltaic assembly, which can fully utilize the gap between adjacent photovoltaic assemblies and increase the power generation of the photovoltaic assembly through reflection.

[0027] like Figure 1 to Figure 2 As shown, a plug for reflective gain of photovoltaic modules, the plug 11 is in the shape of a long strip as a whole, and the plug 11 includes a plug body 10 at the bottom and a reflective element at the top. The reflective element can be a reflective element such as a reflective plate, a reflective film 12, etc. In this embodiment, the reflective film 12 is used, which is light and easy to assemble and disassemble.

[0028] The plug body 10 includes a rectangular bottom and a prism top. The rectangular bottom can be flexibly inserted into the gap between adjacent photovoltaic modules 20. The prism top has multiple inclined surfaces, which can achieve a multi-angle reflective effect in conjunction with the reflective film 12. In this embodiment, the prism is a triangular prism, and the cross section of the plug 11 is arrow-shaped as a whole. Furthermore, the two inclined surfaces of the triangular prism are inclined surfaces that are symmetrical about the central axis of the plug body 10, that is, the cross section of the triangular prism is roughly an isosceles triangle, and the bottom side of the triangle can completely cover the gap between adjacent photovoltaic modules 20. The inclination angle of the inclined surface can be adjusted according to the specific setting of the photovoltaic module 20 to ensure that the reflected light can be projected onto the photovoltaic panel of the photovoltaic module 20. In this embodiment, the angle between the symmetrical inclined surfaces is α, 90°≤α≤120°. The reflective film 12 covers the inclined surface, reflects the multi-angle incident light originally incident into the gap to the photovoltaic module 20, and reasonably utilizes the light incident into the gap.

[0029] In this embodiment, cheap and light foam, sponge and other lightweight materials are used as the material of the plug block body 10. The plug block 11 can be plugged and used, and if damaged, it can be replaced at any time due to the low price.

[0030] The utility model also discloses a photovoltaic assembly, wherein the above-mentioned insert block 11 is reasonably arranged in the gap between adjacent photovoltaic assemblies 20. Figure 1 , Figure 3 As shown, the plug 11 is inserted into the gap between adjacent photovoltaic modules 20 along the extending direction of the edge of the photovoltaic module 20. Since the plug 11 has two symmetrical inclined surfaces, and the inclined surfaces are affixed with a reflective film 12. When the sunlight directly shines on the reflective film 12, the reflective film 12 refracts the light, and the refracted light enters the photovoltaic panel, and the photovoltaic panel generates electricity. Figure 4 As shown, four components are installed with four plug blocks 11; Figure 5 As shown, 7 plugs 11 are installed in the gaps between 6 photovoltaic modules. The plugs 11 can be installed in the gaps between two photovoltaic modules 20 in the horizontal direction, or in the installation gaps between two photovoltaic modules 20 in the vertical direction.

[0031] like Figure 1-Figure 5 As shown, the edge of the photovoltaic module is snapped into the mounting frame 21. The mounting frame 21 has a snap-in portion, one end of which is open, and the edge of the photovoltaic module is inserted into the opening and fixed. The side of the mounting frame 21 is in contact with the side of the plug. A plurality of mounting beams 31 are provided on the backlight side of the photovoltaic module, and the mounting beams 31 are fixed to the photovoltaic bracket 30 to achieve the overall fixation of the photovoltaic module.

[0032] Implementation of the utility model:

[0033] Insert the plug 11 into the gap between adjacent photovoltaic modules, and the top slope of the plug is affixed with a reflective film 12, which can reflect part of the light source to the surface of the photovoltaic module's light-receiving cell. When the sunlight directly hits the reflective film 12, it is refracted to the light-receiving cell of the photovoltaic module 20, increasing the light intensity of the photovoltaic module 20 and improving the power generation of the photovoltaic module 20.

[0034] The utility model effectively solves the problem of light intensity loss caused by gaps between components during installation. At the same time, due to its unique and simple design, the device can make more effective use of this part of the loss, and can be easily disassembled, replaced, maintained, and its material cost is relatively low, making this reflective gain plug more cost-effective. The utility model is suitable for large-scale photovoltaic power stations installed in large-scale arrays, making full use of the gaps between photovoltaic components and increasing the power generation of existing photovoltaic power stations.

[0035] Finally, it should be noted that the above is only a preferred implementation case of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents.
