Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of solar energy, and more specifically to a double-glass solar energy component. Background Art
[0002] Double-glass solar panels are a type of solar cell panels in the photovoltaic industry. Double-glass solar panels have higher light transmittance, stronger wind resistance and weather resistance, and longer service life. In addition, double-glass solar panels also have the characteristics of double-sided power generation. They can not only generate electricity using sunlight from the front of the panel, but also generate electricity using sunlight from the back of the panel, thereby improving power generation efficiency. They are widely used in agricultural planting, construction, roads, bridges and other fields.
[0003] Deficiencies of the prior art: Double-glass solar panels in the prior art are usually formed by laminating two front and rear glass, a film layer and solar cells at high temperature using a laminator to form a composite layer. Since double-glass solar panels are usually installed outdoors for solar radiation, long-term exposure will cause the double-glass solar panels to generate high temperatures, and the film layer is easy to melt under high temperature conditions. The melted film layer will flow inside the component and block the surface of the solar cell, affecting the normal use of the double-glass solar panels. Utility Model Content

[0011] Technical effects and advantages of the utility model:
[0012] 1.

Since the double-glass solar module is a composite layer formed by high-temperature lamination of a laminator, the solar module is fixed by the packaging frame 1 to avoid cracking. The packaging frame 1 facilitates the installation of the solar module while ensuring the integrity of its structure. A solar cell layer 6 is fixedly connected between the rear EVA film layer 4 and the front EVA film layer 5, and packaging components 7 are fixedly connected to the left and right ends of the front glass plate 2 and the rear glass plate 3.
[0021] Furthermore, the rear EVA film layer 4 and the front EVA film layer 5 are made of ethylene-vinyl acetate copolymer, and the front glass plate 2 and the rear glass plate 3 are fixed by the rear EVA film layer 4 and the front EVA film layer 5. The front glass plate 2 and the rear glass plate 3 are made of semi-tempered glass. Semi-tempered glass has better light transmittance and longer service life, which can effectively improve the light transmittance of the double-glass solar panel.
[0022] Further, such as Figure 3As shown, the packaging component 7 includes a first fixed block 71 and a second fixed block 72. The shapes and sizes of the first fixed block 71 and the second fixed block 72 are adapted to each other. The first fixed block 71 and the second fixed block 72 are respectively fixedly connected to the left and right ends of the front glass plate 2 and the rear glass plate 3. The tightness of the connection between the front glass plate 2 and the rear glass plate 3 is ensured by the first fixed block 71 and the second fixed block 72. A first packaging groove 73 is provided on the inner wall of the first fixed block 71, and a first inclined surface 74 is provided on the bottom end of the first fixed block 71. A second packaging groove 75 is provided on the inner wall of the second fixed block 72, and a second inclined surface 76 is provided on the top end of the second fixed block 72.

[0023] Further, such as Figure 4 As shown, the positions of the first packaging groove 73 and the second packaging groove 75 correspond to each other, the front EVA film layer 5 and the rear EVA film layer 4 are fixedly connected to the inner cavities of the first packaging groove 73 and the second packaging groove 75 respectively, and the first packaging groove 73 and the second packaging groove 75 protect the front EVA film layer 5 and the rear EVA film layer 4, and at the same time can reduce the exposure to sunlight, the first slope 74 and the second slope 76 correspond to each other, the first slope 74 and the second slope 76 are connected to each other, and the front EVA film layer 4 and the rear EVA film layer 5 will flow after being melted by the high temperature of the sun, and flow outward through the first slope 74 and the second slope 76, so as to avoid flowing inward and causing the surface of the solar cell layer 6 to be blocked, thereby affecting the normal use of the solar cell.
[0024] The working principle of the utility model is as follows: first, the front glass plate 2, the rear glass plate 3, the rear EVA film layer 4, the front EVA film layer 5 and the solar cell layer 6 are laminated at high temperature by a laminating machine to form a composite layer, and the solar module is fixed by a packaging frame 1 to avoid cracking, so as to facilitate the installation of the solar module and ensure the integrity of its structure.

The front EVA film layer 5 and the rear EVA film layer 4 are protected by the first packaging groove 73 and the second packaging groove 75 to reduce the exposure to sunlight. The front EVA film layer 4 and the rear EVA film layer 5 will flow after being melted by the high temperature of sunlight, and flow outward through the first inclined surface 74 and the second inclined surface 76. The guide plate 77 is used to prevent the inward flow that causes the surface of the solar cell layer 6 to be blocked.
