Description

A wave-surface solar photovoltaic power generation panel Technical Field

[0001] The present invention relates to the technical field of photovoltaic power generation panels, and in particular to a wave-surface solar photovoltaic power generation panel. Background Art

[0002] The cells of existing solar panels are all installed flatly. Such flat solar panels occupy a large horizontal area, so the power generation efficiency per unit area is low. Traditional flat solar panels use overall packaging, which requires a thicker shell for support and must be packaged with relatively thick large flat glass. The overall weight is heavy and not convenient for packaging and transportation. In addition, after the traditional solar panels are installed, if the surface is damaged by hard objects falling from the sky, the entire product must be scrapped and replaced, and the maintenance cost is high.

[0003] Summary of the Invention

[0004] The object of the present invention is to provide a wave-surface solar photovoltaic power generation panel to solve at least one of the above-mentioned problems existing in the prior art.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions:

[0006] A wavy surface solar photovoltaic power generation panel includes a mounting base, wherein the mounting base is provided with a plurality of first inclined mounting positions and a second inclined mounting position, wherein the plurality of first inclined mounting positions and the second inclined mounting positions form a wavy mounting surface at the upper end of the mounting base, wherein the first inclined mounting position and the second inclined mounting position are respectively provided with a first solar cell and a second solar cell, wherein the angle between the first solar cell and the second solar cell is ∠A, and 55°≤∠A≤65°.

[0007] Furthermore, in order to ensure the installation area of ​​the solar cell per unit area to a greater extent without affecting the power generation efficiency, ∠A=60°, and the angle between the first solar cell and the horizontal line and the angle between the second solar cell and the horizontal line are equal.

[0008] Furthermore, in order to facilitate the installation and fixation of the first solar cell and the second solar cell, the first inclined mounting position and the second inclined mounting position are both inclined surfaces, and the first solar cell and the second solar cell are fixedly mounted on the first inclined mounting position and the second inclined mounting position by fixing parts.

[0009] Furthermore, in order to increase the service life of the mounting base, the mounting base is made of UV-resistant plastic.

[0010] Furthermore, in order to facilitate the series connection of adjacent solar panels through wires while avoiding the safety hazards of wire leakage, the mounting base includes a mounting shell and a bottom cover fixedly mounted on the lower end of the mounting shell, the first inclined mounting position and the second inclined mounting position are both formed on the upper end surface of the mounting shell, and the bottom cover is provided with an outlet box.

[0011] Furthermore, in order to facilitate wiring and line connection inside the installation shell, wiring holes are provided on the first inclined installation position and the second inclined installation position, and the wiring holes are connected to the interior of the installation shell.

[0012] Furthermore, in order to meet the size requirements of the mounting base, a plurality of first solar cells or second solar cells are provided on the first inclined mounting position and / or the second inclined mounting position along the length direction thereof.

[0013] Furthermore, in order to better realize the series connection between adjacent solar cells and avoid wire leakage while ensuring the inclined installation angle, the first solar cell and the second solar cell are both independently packaged photovoltaic cells.

[0014] Furthermore, the independently packaged photovoltaic cell includes a transparent sheet, a monocrystalline silicon wafer and a PCB transfer circuit board arranged in sequence, the positive and negative poles of the monocrystalline silicon wafer are respectively connected to the positive and negative poles on the PCB transfer circuit board, and the PCB transfer circuit board is provided with positive and negative terminal terminals.

[0015] Furthermore, in order to facilitate wiring inside the mounting shell and realize the series connection of adjacent solar cells, the positive and negative terminal blocks correspond to the wiring holes, and wires are provided inside the mounting shell. The wires are connected to the corresponding positive and negative terminal blocks so that several first solar cells and second solar cells are connected in series.

[0016] The present invention has the following beneficial effects: In this technical solution, the mounting base is provided with a plurality of first and second inclined mounting positions, and a wavy mounting surface is formed on the mounting base. The first and second inclined mounting positions facilitate the inclined mounting of the first and second solar cells. Since the angle between the first and second solar cells is ∠A, 55°≤∠A≤65°, this mounting method allows for a larger area of ​​cells to be installed per unit area compared to a flat mounting method. Given a fixed unit area, the wavy surface solar photovoltaic panel achieves higher power generation efficiency. Similarly, for the same wattage, the area of ​​the wavy surface solar photovoltaic panel can be smaller. Furthermore, because the wavy mounting surface itself provides a strong reinforcing rib effect, the mounting base housing can be thinner, resulting in a lighter weight. Furthermore, the first and second solar cells of the wavy surface solar photovoltaic panel are each independent small pieces, each of which can be encapsulated with thin glass, while traditional flat solar panels must be encapsulated with thicker, flat glass. Consequently, the weight of this portion of the wavy surface solar photovoltaic panel is reduced. Overall, a wave-surface solar photovoltaic panel with the same power output can be approximately 40% lighter than a traditional flat solar panel. After installation, if a hard object falls from the sky and damages the surface of a traditional solar panel, the entire panel must be scrapped and replaced. However, the first and second solar cells in a wave-surface solar photovoltaic panel are individually encapsulated into small pieces. If a hard object falls from the sky and damages the surface, only the damaged first or second solar cell needs to be replaced for continued use, resulting in lower maintenance costs.

DETAILED DESCRIPTION

[0023] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly introduced below in conjunction with the drawings and the description of the embodiments or the prior art. Obviously, the following description of the structure of the drawings is only some embodiments of the present invention. For those skilled in the art, other drawings can be obtained based on these drawings without creative work. It should be noted that the description of these embodiments is used to help understand the present invention, but does not constitute a limitation of the present invention.

[0024] Example 1:

[0025] As shown in Figures 1 to 5, this embodiment provides a wavy surface solar photovoltaic power generation panel, including a mounting base, on which are provided a plurality of first inclined mounting positions 1 and second inclined mounting positions 2, wherein the plurality of first inclined mounting positions 1 and second inclined mounting positions 2 form a wavy mounting surface at the upper end of the mounting base, and the first inclined mounting positions 1 and the second inclined mounting positions 2 are respectively provided with first solar cells 3 and second solar cells 4, and the angle between the first solar cell 3 and the second solar cell 4 is ∠A, 55°≤∠A≤65°.

[0026] In this technical solution, the mounting base is provided with a plurality of first and second inclined mounting positions 1 and 2, forming a wavy mounting surface. These first and second inclined mounting positions 1 and 2 facilitate the tilted mounting of the first and second solar cells 3 and 4. Since the angle between the first and second solar cells 3 and 4 is ∠A, 55°≤∠A≤65°, this mounting method allows for a larger area of ​​cells to be installed per unit area compared to a flat mounting method. Given a fixed unit area, the wavy surface solar photovoltaic panel achieves higher power generation efficiency. Similarly, for the same wattage, the area of ​​the wavy surface solar photovoltaic panel can be smaller. Furthermore, because the wavy mounting surface provides a strong reinforcing rib effect, the mounting base housing can be thinner, resulting in a lighter weight. Furthermore, the first and second solar cells 3 and 4 of the wavy surface solar photovoltaic panel are each individually encapsulated with thin glass, whereas traditional flat solar panels must be encapsulated with thicker, flat glass. Consequently, the weight of this portion of the wavy surface solar photovoltaic panel is also reduced. Overall, a wave-surface solar photovoltaic panel with the same power output can be approximately 40% lighter than a traditional flat solar panel. After installation, if a hard object falls from the sky and damages the surface of a traditional solar panel, the entire panel must be scrapped and replaced. However, the first and second solar cells 3 and 4 of a wave-surface solar photovoltaic panel are individually encapsulated in small pieces. If a hard object falls from the sky and damages the surface, only the damaged first or second solar cell 3 and 4 need to be replaced for continued use, resulting in lower maintenance costs.

[0027] Example 2:

[0028] This embodiment is optimized based on the above embodiment 1.

[0029] In order to ensure the installation area of ​​the solar cell within a unit area to a greater extent without affecting the power generation efficiency, ∠A=60°, and the angle between the first solar cell 3 and the horizontal line and the angle between the second solar cell 4 and the horizontal line are equal.

[0030] The first solar cell 3 and the second solar cell 4 are symmetrically installed at an angle of 60 degrees, which can ensure the stability of the installation. At the same time, more solar panels can be installed per unit area, and the power generation efficiency can also be guaranteed. The power generation voltage and current are almost no different from the output current and voltage of the traditional flat installation. If the 60° groove direction of the solar panel is consistent with the direction of the sun during installation, the power generation effect is more ideal.

[0031] Example 3:

[0032] This embodiment is optimized based on the above embodiment 1.

[0033] In order to facilitate the installation and fixation of the first solar cell 3 and the second solar cell 4, the first inclined mounting position 1 and the second inclined mounting position 2 are both inclined surfaces, and the first solar cell 3 and the second solar cell 4 are fixedly mounted on the first inclined mounting position 1 and the second inclined mounting position 2 by fixing members 5. The fixing members 5 can be fixing plates fixed to the first inclined mounting position 1 and the second inclined mounting position 2 by screws, and the two symmetrical fixing plates can clamp the first solar cell 1 or the second solar cell 2.

[0034] Example 4:

[0035] This embodiment is optimized based on the above embodiment 1.

[0036] To increase the lifespan of the mount, the mount is made of UV-resistant plastic.

[0037] Example 5:

[0038] This embodiment is optimized based on the above embodiment 1.

[0039] In order to facilitate the series connection of adjacent solar panels through wires and avoid the safety hazards of wire leakage, the mounting base includes a mounting shell 6 and a bottom cover plate 7 fixedly installed at the lower end of the mounting shell 6. The first inclined mounting position 1 and the second inclined mounting position 2 are both formed on the upper end surface of the mounting shell 6, and an outlet box 8 is provided on the bottom cover plate 7.

[0040] Example 6:

[0041] This embodiment is optimized based on the above embodiment 5.

[0042] In order to facilitate wiring and line connection inside the mounting housing 6 , wiring holes 14 are provided on both the first inclined mounting position 1 and the second inclined mounting position 2 , and the wiring holes 14 are connected to the interior of the mounting housing 6 .

[0043] Example 7:

[0044] This embodiment is optimized based on the above embodiment 1.

[0045] In order to meet the size requirements of the mounting base, multiple first solar cells 3 or second solar cells 4 are provided on the first inclined mounting position 1 and / or the second inclined mounting position 2 along their length direction. In this embodiment, two first solar cells 3 or second solar cells 4 can be optionally arranged side by side along the length direction of the first inclined mounting position 1 and / or the second inclined mounting position 2.

[0046] Example 8:

[0047] This embodiment is optimized based on the above embodiment 6.

[0048] In order to better realize the series connection between adjacent solar cells and avoid leakage of the wire 13 while ensuring the inclined installation angle, the first solar cell 3 and the second solar cell 4 are both independently packaged photovoltaic cells.

[0049] Example 9:

[0050] This embodiment is optimized based on the above-mentioned embodiment 8.

[0051] As shown in Figure 5, the independently packaged photovoltaic cell includes a transparent sheet 9, a single crystal silicon wafer 10 and a PCB transfer circuit board 11 arranged in sequence. The positive and negative poles of the single crystal silicon wafer 10 are respectively connected to the positive and negative poles on the PCB transfer circuit board 11. The PCB transfer circuit board 11 is provided with positive and negative terminal 12. The transparent sheet 9 can be transparent glass.

[0052] Independently packaged photovoltaic cells are made of a three-layer laminate package consisting of a transparent sheet 9, a single-crystal silicon wafer 10, and a PCB transfer circuit board 11. Since solar cells are not installed flat in the traditional sense, the single-crystal silicon wafer 10 cannot be connected flat with traditional soldering ribbons and then covered with a large piece of flat glass or transparent plastic sheet for laminate packaging. The silicon wafer can only be divided into long strips with a width corresponding to the inclined surface for packaging. In addition, since each solar cell is folded and connected, it cannot be connected with traditional conductive soldering ribbons. If the conductive soldering ribbons are exposed to the outside, they will leak electricity and are also easy to break. Therefore, it is necessary to add a PCB transfer circuit board 11 behind the single-crystal silicon wafer 10 to transfer the positive and negative lines on the single-crystal silicon wafer 10 to the output on the PCB circuit board. After installation on the mounting seat, the lines are connected inside the mounting shell.

[0053] Example 10:

[0054] This embodiment is optimized based on the above-mentioned embodiment 9.

[0055] In order to facilitate wiring inside the installation shell and realize the series connection of adjacent solar cells, the positive and negative terminal blocks 12 correspond to the wiring holes 14, and a wire 13 is provided in the installation shell 6. The wire 13 is connected to the corresponding positive and negative terminal blocks 12 so that several first solar cells 3 and second solar cells 4 are connected in series.

[0056] The existing flat installation of a cell length, the use of this technical solution can be installed two cells, that is to say, to make a power generation cell panel of the same wattage, the area of ​​the wave surface solar photovoltaic panel is reduced. Similarly, if the power generation efficiency per unit area of ​​the traditional photovoltaic panel is 185W / M2 If the wave surface solar panels are installed, the power generation efficiency per unit area is 370W / M 2 The power generation efficiency has also been improved.

[0057] Finally, it should be noted that the above are only preferred embodiments of the present invention and are not intended to limit the scope of protection of the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention shall be included in the scope of protection of the present invention.
