[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] In the field of photovoltaic power generation, the pyramid-shaped three-dimensional photovoltaic module is an innovative photovoltaic module design that aims to improve the power generation efficiency and space utilization of the photovoltaic system. Traditional planar photovoltaic modules can only utilize the energy of vertical sunlight, while three-dimensional photovoltaic modules can accommodate more photovoltaic cells in a smaller space by designing a pyramid-shaped structure, thereby increasing the power generation per unit area and optimizing space utilization.

[0027] Embodiment 1:

[0028] Combination Figure 1-Figure 6 As shown, the existing photovoltaic module is a rectangular parallelepiped. In order to allow the battery cell 103 to cover its surface to the maximum extent, the battery cell 103 needs to be square. Therefore, the circular silicon wafer needs to be cut into a square. However, this cutting will cause a lot of silicon wafer waste and increase the purchase cost of the battery cell 103. The utility model provides a pyramid-shaped three-dimensional photovoltaic module. Multiple legs serve as carriers of the entire device. A frame 200 is provided on two legs. The frame 200 is used to absorb solar energy. The laminate 100 is placed upright and tilted through the frame 200, which is conducive to rainwater washing, reduces the accumulation of dust and dirt, keeps the surface of the photovoltaic panel clean, and improves the power generation efficiency of the photovoltaic system. Multiple frames 200 are connected in pairs by connecting components 300, which can increase the structural stability of the photovoltaic panel, reduce the impact of wind and external forces on the photovoltaic system, and improve the reliability and durability of the system.

[0029] The cells 103 in the laminate 100 are directly exposed to the outside and are easily subject to mechanical damage from the external environment, such as collision, extrusion, etc., which may cause the cells 103 to break or be damaged, thereby affecting the normal power generation efficiency of the photovoltaic module. The laminate 100 is composed of a panel 101, an encapsulation layer a102, cells 103, an encapsulation layer b104, and a backplane 105. The laminate 100 is a regular polygon. According to geometric knowledge, under the premise that the radius of a circular silicon wafer is the same, the loss caused by cutting the cell 103 into a regular polygon is less than the loss of the silicon wafer caused by cutting it into a square.

[0030] Lacking good support from a fixing frame, photovoltaic panels are easily affected by external environmental factors such as wind and rain, causing the photovoltaic panels to shake or tilt, thereby reducing the stability of the photovoltaic system. A frame 200 is provided for properly installing the laminate 100. The frame 200 includes a main body a201 and a main body b203 respectively fixed to the legs, the main body a201 and the main body b203 are symmetrically distributed, and support portions 202 are fixed to adjacent sides of the main body a201 and the main body b203, and the laminate 100 is bonded to the two support portions 202.

[0031] Furthermore, the encapsulation layer a102 and the encapsulation layer b104 include a photovoltaic encapsulation film, which is a bonding material between the panel 101, the battery cell 103 and the back plate 105, and the photovoltaic encapsulation film is composed of ethylene-vinyl acetate copolymer.

[0032] According to the embodiments, the pyramid-shaped design can expose more photovoltaic panels to sunlight, increase the amount of light absorbed, and improve the power generation efficiency of the photovoltaic system.

[0033] Embodiment 2:

[0034] Combination Figure 1-Figure 6 As shown, on the basis of Example 1, multiple laminated parts 100 are placed separately, occupying a large space and being greatly affected by external wind force. The connecting component 300 includes multiple connecting sleeves 301 arranged between the main body a201 and the main body b203. Both sides of the connecting sleeves 301 are slidably connected with sliding rods 302, and the sliding rods 302 are hinged with connecting strips 303, and the connecting strips 303 are hinged with transmission plates 304. The transmission plates 304 on both sides are fixed to the main body a201 and the main body b203 by bolts respectively, which saves ground space, improves land utilization, and is suitable for situations where the site is limited.

[0035] Specifically, the laminate 100 is provided with wire insertion slots 106 , and the wire insertion slots 106 are connected by wires.

[0036] Furthermore, the frame 200 is provided with a plurality of them, and the whole can be composed of a triangular pyramid, a pentagonal pyramid, etc. The cone shape composed of fewer edges can arrange the photovoltaic panels more compactly, saving space, and is particularly suitable for arranging photovoltaic systems in places with limited space. The cone shape composed of more edges is more stable, can withstand greater wind and external forces, and improves the stability and durability of the system.

[0037] It can be seen from the above embodiments that the pyramid shape can receive light at different angles, adapt to power generation needs in different time periods and lighting conditions, and improve the power generation efficiency of the system.

[0038] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
