[0048] Reference Figure 1 、 Figure 2 、 Figure 3 The photovoltaic array 100 provided in this application includes a bracket 10 and a plurality of photovoltaic components 50 . Figure 2 This is a schematic diagram of the structure of one side of the mounting plate 30 where the photovoltaic module 50 is provided. Figure 3 yes Figure 1 A top view of Figure 3 In the embodiment, the solar cells on each photovoltaic module 50 are omitted.

[0049] The bracket 10 includes a base 20 and multiple mounting plates 30. One end of each mounting plate 30 is connected to the base 20, and the mounting plates 30 are arranged around the entire circumference of the base 20. At least two photovoltaic modules 50 are installed on the same side of each mounting plate 30. The outer contour of the structure formed by all photovoltaic modules 50 on the same mounting plate 30 matches the outer contour of the mounting plate 30.

[0050] One end of each mounting plate 30 is connected to the base 20, and each mounting plate 30 is arranged around the entire circumference of the base 20, so that the entire photovoltaic array 100 is petal-shaped. Compared with the photovoltaic components 50 arranged in columns and rows, it has a certain sense of design and better ornamental properties, which greatly improves the user experience.

[0051] In addition, at least two photovoltaic modules 50 are installed on the same side of each mounting plate 30. The outer contour of the structure formed by all the photovoltaic modules 50 on the same mounting plate 30 matches the outer contour of the mounting plate 30. In this way, the coverage of each mounting plate 30 is covered by the structure formed by at least two photovoltaic modules 50. In the case that the shape of the mounting plate 30 is not a regular rectangle, the coverage on the mounting plate 30 can be covered as fully as possible by increasing the number of photovoltaic modules 50. In this way, the shape of the mounting plate 30 can be set according to the actual shape required, which is more flexible. Even if it is set to an irregular shape, the coverage of the mounting plate 30 can be maximized to set the photovoltaic modules 50, which makes the space utilization rate on the mounting plate 30 higher in this application. Furthermore, since one end of each mounting plate 30 is connected to the base 20 and each mounting plate 30 is arranged around the entire circumference of the base 20, even when the photovoltaic array 100 is in an irregular placement space, the size of each mounting plate 30 and the spacing between them can be changed to adapt to such irregular space, which further improves the utilization of space.

[0052] In the embodiment of the present application, the arrangement of the mounting plates 30 around the entire circumference of the base 20 means that the mounting plates 30 surround the circumference of the base 20 and are arranged within a 360° range of the circumference. The outer contour of the mounting plate 30 refers to the side edge of the plate surface of the mounting plate 30, and the outer contour of the structure formed by all the photovoltaic modules 50 on the same mounting plate 30 refers to the overall side edge of the formed structure. The outer contour of the structure formed by all the photovoltaic modules 50 on the same mounting plate 30 matches the outer contour of the mounting plate 30, which means that when viewed from above, the outer contour of the structure roughly coincides with the outer contour of the mounting plate 30, such as Figure 2 shown.

[0053] In a specific implementation, the photovoltaic module 50 can be bonded to the corresponding mounting plate 30 by adhesive. The adhesive can be, for example, a photovoltaic sealant, the ingredients of which are silicone rubber, modified silane, etc.

[0054] In the present application, continue to refer to Figure 1 、 Figure 2 and Figure 3 The mounting plate 30 includes at least one corner portion 31 , and the corner portion 31 includes two first surfaces 311 spaced apart and opposite to each other in the circumferential direction of the base 20 .

[0055] The corner portion 31 of the mounting plate 30 is connected to the base 20 . In adjacent mounting plates 30 , the distance between two adjacent first surfaces 311 along the circumference of the base 20 is smaller than a preset value.

[0056] With this arrangement, the mounting plates 30 can be roughly integrated around the circumference of the base 20, enhancing the aesthetics of the photovoltaic array 100. In practice, the profiles of the mounting plates 30 can be identical, allowing them to be evenly distributed around the base 20. The preset spacing can be relatively small, as long as it does not interfere with the rotation of the mounting plates 30 relative to the base 20.

[0057] exist Figure 3 In the example, seven mounting plates 30 form a full circumference, and the angle between the two first surfaces 311 on any mounting plate 30 may be 51.4°.

[0058] In the embodiment of the present application, the projection of the outer contour of the mounting plate 30 onto a first plane is a sector ring, fan, triangle, or trapezoid. The first plane is perpendicular to the axial direction of the structure formed by the mounting plates 30 arranged around the entire circumference. The mounting plates 30 can be flat or curved. When the mounting plates 30 are curved, for example, the mounting plates 30 can all be located on the same circumferential surface. When the mounting plates 30 are flat, for example, the mounting plates 30 can all be located on the same plane.

[0059] Figure 1 、 Figure 2 、 Figure 3 The illustrated case is an example in which the mounting plate 30 is configured as a curved surface, and the projection of the mounting plate 30 on the first plane is a sector ring. Figure 4 、 Figure 5 The illustrated case is an example in which the mounting plate 30 is configured as a plane, and the projection of the mounting plate 30 on the first plane is a triangle. Figure 6 、 Figure 7 The illustrated case is an example of a mounting plate 30 configured as a plane, and the projection of the mounting plate 30 on the first plane is a sector. Of course, the case where the projection of the mounting plate 30 on the first plane is a trapezoid is similar to a triangle and will not be described in detail herein.

[0060] In the embodiment of the present application, the photovoltaic modules 50 mounted on the same mounting plate 30 are arranged in multiple rows along a first direction starting from the corner 31, where the first direction is the radial direction of the structure formed by the mounting plates 30 arranged around the entire circumference. There is at least one photovoltaic module 50 in each row.

[0061] With such arrangement, each mounting plate 30 is composed of a plurality of small photovoltaic modules 50 , and the area of ​​the mounting plate 30 is not wasted, thereby maximizing the utilization of the area of ​​the mounting plate 30 for power generation.

[0062] Of course, in specific implementation, the corners 31 of each photovoltaic assembly 50 may be provided with chamfers to increase the aesthetics.

[0063] Further, combined with Figure 2 and Figure 3 When the projection of the mounting plate 30 on the first plane is a fan ring, there are two photovoltaic modules 50 in the first row closest to the corner 31, and the projections of these two photovoltaic modules 50 on the first plane are fan rings. There are also two photovoltaic modules 50 in the second row, and the projections of these two photovoltaic modules 50 on the first plane are both fan rings.

[0064] Further, combined with Figure 4 and Figure 5 When the projection of the mounting plate 30 on the first plane is a triangle or trapezoid, there is one photovoltaic module 50 in the first row closest to the corner 31, and the projection of this one photovoltaic module 50 on the first plane is a triangle or trapezoid. There are two photovoltaic modules 50 in the second row, and the projections of these two photovoltaic modules 50 on the first plane are both right-angled trapezoids. Of course, if there are more rows, the number of photovoltaic modules 50 in any of the remaining rows can also be two, and the projections of these two photovoltaic modules 50 on the first plane are both right-angled trapezoids.

[0065] Combine Figure 6 and Figure 7When the projection of the mounting plate 30 on the first plane is a fan-shaped, there is one photovoltaic module 50 in the first row closest to the corner 31, and the projection of this one photovoltaic module 50 on the first plane is a fan-shaped. The number of photovoltaic modules 50 in the remaining rows is two, and the projection of these two photovoltaic modules 50 on the first plane is a fan-shaped ring.

[0066] exist Figure 4 、 Figure 5 、 Figure 6 and Figure 7 In the example, eight mounting plates 30 form a full circumference. Figure 4 、 Figure 5 When the profile of the mounting plate 30 is a triangle, the vertex of the corner 31, that is, the included angle between the two first surfaces 311 of the same mounting plate 30, is 45°. Figure 6 、 Figure 7 When the mounting plate 30 has a sector-shaped profile, the vertex angle of the sector, i.e., the included angle between the two first surfaces 311 of the same mounting plate 30, is 45°. Of course, when the number of mounting plates 30 is different, the angle between the two first surfaces 311 of the corner portion 31 can be determined based on actual needs. For example, when the profiles of all mounting plates 30 are identical, the included angle can be: 360° / number of mounting plates.

[0067] In addition, the photovoltaic modules 50 on each mounting plate 30 can be closely laid, so that each mounting plate 30 is fully covered with photovoltaic modules 50, and no gaps are left between the photovoltaic modules 50. Alternatively, the photovoltaic modules 50 on each mounting plate 30 can also be provided with gaps as needed.

[0068] For the electrical connection of the photovoltaic modules 50 , the photovoltaic modules 50 of the same shape may be connected in series, and then the photovoltaic modules 50 connected in series may be connected in parallel.

[0069] In the present application, continue to refer to Figure 1 The mounting plate 30 is provided with a hollow structure (not shown), and the bracket 10 further includes a leg 40 connected to the base 20, and the leg 40 is constructed as a hollow structure. The connection cable of the photovoltaic module 50 is accommodated in the leg 40.

[0070] This arrangement can prevent the cables of the photovoltaic module 50 from being exposed, making the appearance of the photovoltaic array 100 more beautiful, and at the same time, can also prevent damage to the cables from the external environment. In addition, it also facilitates ventilation and heat dissipation of the photovoltaic module 50, keeping it at a good operating temperature.

[0071] Further, refer to Figure 8 The photovoltaic array 100 further includes a controller 60 , and a driving component 70 and a detection component (not shown) electrically connected to the controller 60 .

[0072] The detection component is used to detect the illuminance and the force value of the photovoltaic component 50. The controller 60 is used to control the driving component 70 to drive the photovoltaic component 50 to rotate relative to the base 20 according to the illuminance and force value detected by the detection component.

[0073] In specific implementation, the change in light intensity detected by the detection component reflects the direction of light. The controller 60 can drive the photovoltaic component 50 to rotate by controlling the driving component 70, that is, by controlling the rotation angle of the photovoltaic component 50, so that the light intensity detected by the detection component is always greater than the preset illuminance, thereby ensuring that the photovoltaic component 50 always tracks the sun.

[0074] In addition, the force value detected by the detection component reflects the force condition of the photovoltaic component 50. For example, if strong winds occur, in order to avoid excessive frontal pressure exerted by the strong wind on the photovoltaic component 50, when the force value detected by the detection component is greater than the preset force value, the controller 60 can control the driving component 70 to drive the photovoltaic component 50 to rotate to a smaller angle with the wind direction, so that the force value detected by the detection component is less than the above-mentioned preset force value.

[0075] Furthermore, the drive assembly 70 includes a motor 71, a driving wheel 72, a driven wheel 73, and a belt 74 stretched on the driving wheel 72 and the driven wheel 73. The driving end of the motor 71 is connected to the driving wheel 72, and the driven wheel 73 is used to drive the mounting plate 30 to rotate relative to the base 20.

[0076] With this arrangement, when the mounting plate 30 needs to be adjusted, the controller 60 drives the motor 71 to rotate, so that the driving wheel 72 drives the driven wheel 73 to rotate, and the driven wheel 73 drives the mounting plate 30 to rotate.

[0077] In the present application, refer to Figure 9 The photovoltaic module 50 includes a cell 54, a first film layer 51, a reinforcement layer 55, a second film layer 52, a front plate 56, a third film layer 53 and a back plate 57; the first film layer 51, the reinforcement layer 55, the second film layer 52, and the front plate 56 are sequentially stacked on the light-receiving surface of the cell 54, and the third film layer 53 and the back plate 57 are sequentially stacked on the backlight surface of the cell 54.

[0078] In this manner, the reinforcement layer 55 can enhance the strength of the light-receiving surface of the cell 54. For example, it can protect the front of the cell 54 from hail and impact. The reinforcement layer 55 can better protect the cell 54, especially when the front panel 56 is made of a polymer material with poor hardness.

[0079] The reinforcement layer 55 is a plate formed by solidifying filler and resin. The filler is a mesh-woven glass fiber, and the resin is a thermosetting resin such as polyacrylic resin, epoxy resin, polyurethane, etc. The reinforcement layer 55 can be manufactured by hand lay-up molding, injection molding, bag compression molding and other processes.

[0080] The back sheet 57 may be a single-layer or multi-layer co-extruded polymer back sheet, such as TPT, TPE, PE, etc. The first adhesive film layer 51, the second adhesive film layer 52, and the third adhesive film layer 53 may be at least one of EVA, POE, PVB, and TPU.

[0081] Furthermore, the front panel 56 includes a film topcoat layer, a substrate, and a weather-resistant layer (not shown) stacked sequentially on the side of the second film layer 52 facing away from the cell 54. The weather-resistant layer is configured to block ultraviolet light, and the film topcoat layer is configured to enhance adhesion to the second film layer 52.

[0082] The weather-resistant layer may be a weather-resistant coating or a weather-resistant film, which can block ultraviolet light, thereby blocking the influence of ultraviolet radiation on the battery cell 54 and slowing down the aging speed of the battery cell 54 .

[0083] In a specific implementation, the weather-resistant coating can be a fluorine-containing coating, such as an FC coating, FEP coating, or PFA coating, applied to the substrate surface via a coating process. The weather-resistant film can be made of materials such as PVF, PVDF, PTFE, or ETFE, with a thickness of 10 to 50 μm. The weather-resistant film is applied to the substrate surface via a composite process. The substrate can be a transparent polymer material such as PET, PC, or PMMA, with a thickness of 200 to 600 μm. The adhesive film topcoat can be, for example, a fluorocarbon, PVF, or PVDF coating.

[0084] The technical features of the above-mentioned embodiments can be combined arbitrarily. In order to make the description concise, not all possible combinations of the technical features in the above-mentioned embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0085] The above-described embodiments merely represent several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present utility model patent shall be determined by the appended claims.
