[0001] The present disclosure relates to the technical field of double-sided solar cells, and in particular to a solar panel mounting bracket and a solar power generation device. Background Art
[0002] With the development of solar cell technology, bifacial solar panels have gradually gained attention in the industry. Bifacial solar panels can simultaneously capture or absorb light energy from both the front and back sides and convert it into electricity. They capture light energy by: the solar cells on the front side face the sun and directly capture incoming sunlight, while the solar cells on the back side absorb light reflected from the ground or objects below. This method allows bifacial solar panels to generate electricity using both direct sunlight and reflected light, improving power generation efficiency.
[0003] However, in actual use, since the solar cells on the back can only absorb reflected light from the ground or objects below, and the intensity of this reflected light is weak, there is a problem of low power generation efficiency on the back. Utility Model Content

[0031] Reference Figure 1-Figure 2 The present disclosure provides a solar panel mounting bracket, comprising:
[0032] The mounting base plate 1 is provided with a mounting groove 2 on the upper surface of the mounting base plate 1;
[0033] A mounting frame 3 is mounted above the mounting base plate 1 and is used for mounting a bifacial solar cell panel 7. The mounting frame 3 is formed with an opening area 4 for sunlight to pass through, and the opening area 4 is located below the bifacial solar cell panel 7; and
[0034] The reflective plate 5 is disposed in the mounting groove 2 and is used to reflect sunlight passing downward through the opening area 4 to the back of the double-sided solar cell panel 7 .
[0035] The solar panel mounting bracket is provided with an opening area 4 on the mounting frame 3. Sunlight can pass through the opening area 4 to reach the reflector 5 provided in the mounting base plate 1, and then be guided to the back side of the double-sided solar panel 7 after being reflected by the reflector 5, thereby increasing the intensity of the light received by the back side, thereby improving the power generation efficiency of the back side.
[0036] In some embodiments, the mounting base 1 is fixed to the ground or a building outdoors. The mounting base 1 may have a hollow structure to reduce its weight and facilitate transport. The lower end of the second leg 6 may be fixedly connected to the upper surface of the mounting base 1. The upper end of the second leg 6 is fixedly connected to the mounting frame 3, thereby placing the mounting frame 3 above the mounting base 1.
[0037] In some embodiments, the mounting frame 3 includes a plurality of mutually spaced transverse panels 31 and a plurality of mutually spaced longitudinal panels 32, which are arranged in a crisscross pattern to form a plurality of opening regions 4. This arrangement of the mounting frame 3 allows sufficient sunlight to reach the reflective plate 5 from the plurality of opening regions 4 and reduces the weight of the mounting frame 3. The transverse panels 31 and longitudinal panels 32 extend in the transverse and longitudinal directions, respectively, and are arranged in a crisscross pattern to form a cross-beam structure. This improves the structural strength of the mounting frame 3 and facilitates the regular arrangement of multiple square solar panels on the mounting frame 3.
[0038] like Figure 1-Figure 2 As shown, it should be noted that: the horizontal and vertical directions refer to the x-axis direction and the y-axis direction respectively; the front and back sides of the bifacial solar cell panel 7 refer to its two surfaces facing upward and downward respectively, and the positive direction of the z-axis points upward.
[0039] In some embodiments, the plurality of opening regions 4 are provided with mounting positions arranged in an array, and the mounting positions are used to set up the bifacial solar cell panels 7. Furthermore, a mounting position is provided in each opening region 4, and the solar cell panel can be fixedly set on the mounting position by a fastening structure.
[0040] In some embodiments, the mounting frame 3 further includes a first leg 33 disposed at the mounting position. The first leg 33 is used to support one side of the bifacial solar panel 7 and elevate or raise the side, allowing the bifacial solar panel 7 to be tilted on the mounting frame 3. This facilitates sunlight passing through the raised side through the opening area 4, thereby improving the back-side power generation efficiency. At the same time, it also allows the front of the bifacial solar panel 7 to face the sunlight as directly as possible, improving the front-side power generation efficiency and ensuring high power generation efficiency on both the front and back sides of the bifacial solar panel 7. Furthermore, the tilt angle of the bifacial solar panel 7 exceeds 20° to ensure that sufficient sunlight passes through the raised side through the opening area 4.
[0041] In some embodiments, the upper end of the first support leg 33 is fixedly connected to the bifacial solar panel 7 to secure the bifacial solar panel 7 in the installation position. To enhance the securing effect of the bifacial solar panel 7, two first support legs 33 may be provided on the raised side of the bifacial solar panel 7. The upper ends of the two first support legs 33 are both fixedly connected to the bifacial solar panel 7, thereby firmly securing the bifacial solar panel 7 in the installation position through two fixed connection points.
[0042] The opening area 4 is located below the bifacial solar panel 7. To prevent the bifacial solar panel 7 from completely blocking the opening area 4, the length of the bifacial solar panel 7 is shorter than the length of the opening area 4 in the horizontal direction, and the width of the bifacial solar panel 7 is shorter than the width of the opening area 4 in the vertical direction. For example, in the vertical direction, the width of the bifacial solar panel 7 is two-thirds of the width of the opening area 4, so that sunlight can pass through the unblocked opening area 4 on the side of the bifacial solar panel 7.
[0043] In some embodiments, the reflective plate 5 includes a substrate and a reflective film disposed on the upper surface of the substrate. The substrate provides support for the reflective film and can be a conventional glass or plastic plate. The reflective plate 5 can be secured to the mounting slot 2 using a conventional fastening structure, such as a bolt structure. The reflective film can effectively reflect sunlight reaching its surface and can be a conventional composite reflective film or a metal reflective film. Preferably, the composite reflective film or the metal reflective film has a reflectivity exceeding 90%.
[0044] In some embodiments, the solar panel mounting bracket further includes a second leg 6, the lower end of the second leg 6 being fixedly connected to the mounting base plate 1, and the upper end of the second leg 6 being fixedly connected to the mounting frame 3, so as to erect the mounting frame 3 above the mounting base plate 1. The second leg 6 is a retractable leg, and the height of the upper end of the retractable leg can be adjusted by retracting or extending the leg. A plurality of second legs 6 can be provided, for example, four second legs 6 are provided at the four corners of the mounting frame 3. By providing a plurality of second legs 6, a space can be formed between the mounting base plate 1 and the mounting frame 3, and the surrounding reflected light can reach the reflector 5 from the side of the space, further improving the back-side power generation efficiency.
[0045] Based on the above-mentioned solar panel mounting bracket, the present disclosure further provides a solar power generation device, comprising the above-mentioned solar panel mounting bracket and a bifacial solar panel 7 mounted thereon. This solar power generation device also has the advantages of improving back-side power generation efficiency, simple structure, easy installation, and low cost.
[0046] Continue to refer to Figure 1 The solar panel mounting bracket can be equipped with multiple bifacial solar panels 7 arranged in an array to improve power generation efficiency. Furthermore, a gap is provided between adjacent bifacial solar panels 7 to expose the opening area 4 to sunlight, allowing more sunlight to pass through the opening area 4 and reach the reflector 5.
