Technical Field
[0001] This application relates to the field of photovoltaic equipment technology, and in particular to a photovoltaic system. Background Technology
[0002] In photovoltaic systems, when horizontal water channels and photovoltaic modules are used together, the horizontal frame of the photovoltaic module is often installed inside the water channel. When the horizontal water channel needs to cross two photovoltaic modules horizontally, it will cause interference between the horizontal water channel and the vertical frame of the photovoltaic module. Utility Model Content
[0003] The main objective of this application is to propose a photovoltaic system designed to improve the versatility of a first beam with a transverse water trough structure.
[0004] To achieve the above objectives, the photovoltaic system proposed in this application includes:
[0005] A first photovoltaic module and a second photovoltaic module are arranged adjacent to each other in a first direction and multiple of them are distributed in a second direction. The first direction forms an angle with the horizontal plane. In the second direction, the extension lengths of the first photovoltaic module and the second photovoltaic module are different.
[0006] A first beam is disposed between the first photovoltaic module and the second photovoltaic module. The first beam extends along a second direction, and the length of the first beam corresponds to the extension length of the second photovoltaic module in the second direction. The first beam forms a first water guide channel extending along the second direction. The first water guide channel has a first sidewall and a second sidewall distributed opposite to each other in the first direction. At least one of the first sidewall and the second sidewall has a first folded edge that folds outward from the first water guide channel. The first folded edge covers the light-facing side of at least one of the first photovoltaic modules.
[0007] The second beam extends along the first direction and has multiple beams distributed along the second direction. At least the side of the second photovoltaic module is provided with the second beam. The second beam forms a second water guide channel extending along the first direction. The two ends of the first water guide channel are respectively provided with two second water guide channels.
[0008] In one embodiment, both the first sidewall and the second sidewall are provided with the first folded edge, and the two first folded edges are respectively covered on the light-facing side of the first photovoltaic module and the second photovoltaic module.
[0009] In one embodiment, the first sidewall is provided with the first folded edge, the first folded edge is covered on the light-facing side of the first photovoltaic module, and the second sidewall is located on the back-lighting side of the second photovoltaic module.
[0010] In one embodiment, the first photovoltaic module and the second photovoltaic module are distributed sequentially in a downward inclined direction, and the frame of the second photovoltaic module is installed in the first water guide channel.
[0011] In one embodiment, the second sidewall is provided with a reinforcing structure.
[0012] In one embodiment, the reinforcing structure includes a second folded edge that is folded toward the first sidewall.
[0013] In one embodiment, the reinforcing structure includes a reinforcing rolled edge formed at the opening of the first water guide channel.
[0014] In one embodiment, the reinforcing structure includes at least one reinforcing rib extending along the first direction.
[0015] In one embodiment, the first folded edge has a third folded edge on the side away from the first sidewall. The third folded edge is inclined toward the first photovoltaic module in a direction away from the first folded edge. Both the first photovoltaic module and the second photovoltaic module have a frame. The frame has a first abutting surface and a second abutting surface inclined relative to the first abutting surface on the light-facing side. The first folded edge covers at least the first abutting surface, and the third folded edge covers the second abutting surface.
[0016] In one embodiment, the first folded edge is connected to the first photovoltaic module or the second photovoltaic module by adhesive bonding.
[0017] In one embodiment, a second beam is provided on each side of the first photovoltaic module and on each side of the second photovoltaic module.
[0018] In this application's technical solution, a gap exists between the first photovoltaic module and the second photovoltaic module. A first beam is positioned corresponding to this gap. The first beam is waterproofed to the first photovoltaic module on its first sidewall and to the second photovoltaic module on its second sidewall, ensuring that rainwater falling into the gap can be collected by the first water guide channel, thus eliminating the potential for leakage at this gap. The first beam, by having a first folded edge on the sidewall of the first water guide channel covering the sun-facing side of the photovoltaic module, avoids interference with the photovoltaic module's frame, enhancing the beam's versatility. The first beam can flexibly accommodate photovoltaic modules of different sizes, allowing for more flexible arrangement of the photovoltaic modules in the system, more effectively utilizing available area, and maximizing the number of photovoltaic modules installed.

[0045] This application proposes a photovoltaic system.
[0046] Please see Figure 1 In one embodiment of this application, the photovoltaic system includes a first photovoltaic module 110 and a second photovoltaic module 120. The first photovoltaic module 110 and the second photovoltaic module 120 are arranged adjacent to each other in a first direction and are distributed in a second direction. The first direction forms an angle with the horizontal plane. In the second direction, the extension length L1 of the first photovoltaic module 110 and the extension length L2 of the second photovoltaic module 120 are different.
[0047] The photovoltaic system also includes a first beam 300 and a second beam 400. The first beam 300 is disposed between the first photovoltaic module 110 and the second photovoltaic module 120. The first beam 300 extends along the second direction, and the extension length of the first beam 300 in the second direction corresponds to the extension length L2 of the second photovoltaic module 120 in the second direction. The second beam 400 extends along the first direction and is distributed in multiple ways in the second direction. At least the second photovoltaic module 120 is provided with the second beam 400 on its side. The second beam 400 forms a second water guide channel 410 extending along the first direction. The two ends of the first water guide channel 301 are respectively provided with two second water guide channels 410.
[0048] Please refer to the following: Figure 3 , Figure 5 and Figure 7The first beam 300 is formed with a first water guide channel 301 extending along the second direction. The first water guide channel 301 has a first sidewall 310 and a second sidewall 320 that are distributed opposite to each other in the first direction. At least one of the first sidewall 310 and the second sidewall 320 is provided with a first folded edge 311 that folds outward toward the first water guide channel 301. The first folded edge 311 covers the light-facing side of at least one of the first photovoltaic modules 110.
[0049] In the technical solution of this application, there is a gap between the first photovoltaic module 110 and the second photovoltaic module 120. The first beam 300 is set to correspond to the gap. The first beam 300 is waterproofly matched with the first photovoltaic module 110 on the side where the first side wall 310 is located, and waterproofly matched with the second photovoltaic module 120 on the side where the second side wall 320 is located. This allows rainwater falling into the gap to be received by the first water guide channel 301, which helps to eliminate the risk of water leakage at the gap.
[0050] Specifically, on the side where the first sidewall 310 is located, a first folded edge 311 is formed on the first sidewall 310 and folds outward toward the first water guide channel 301. The first folded edge 311 covers the light-facing side of at least one first photovoltaic module 110, thereby achieving waterproof cooperation between the first beam 300 and the first photovoltaic module 110.
[0051] For the side where the second sidewall 320 is located, there are multiple ways to achieve waterproofing coordination between the first beam 300 and the second photovoltaic module 120.
[0052] Please refer to Figure 2 and Figure 3 Similar to the first sidewall 310, the second sidewall 320 is also provided with a first folded edge 311 that folds outward toward the first water guide channel 301. In this case, the second sidewall 320 can be located between the first photovoltaic module 110 and the second photovoltaic module 120. The corresponding first folded edge 321 is covered on the sun-facing side of the second photovoltaic module 120. By symmetrically setting the first folded edge 311 on the first sidewall 310 and the second sidewall 320, it is beneficial to ensure the mechanical balance of the overall structure of the first beam 300 and enhance the wind pressure resistance and deformation resistance of the first beam 300.
[0053] Alternatively, the second sidewall 320 can be located on the backlight side of the second photovoltaic module 120. In this case, please refer to [link / reference needed]. Figure 4 and Figure 5 A second folded edge 321 is provided on the second sidewall 320, and when the second folded edge 321 is folded toward the first sidewall 310, the second folded edge 321 must also be located on the backlight side of the second photovoltaic module 120. The second folded edge 321 has a strong water-blocking ability to ensure the waterproof capability of the photovoltaic system and reduce the possibility of water leakage.
[0054] Taking the first photovoltaic module 110 as an example, the first folded edge 311 covering the light-facing side of the first photovoltaic module 110 means that at least a portion of the first folded edge 311 is opposite to the side of the first photovoltaic module 110 on the light-facing side, so that at least a portion of the first folded edge 311 overlaps and connects with the side of the first photovoltaic module 110. That is, between the first beam 300 and the first photovoltaic module 110, it is only necessary to ensure that the first folded edge 311 and the side of the first photovoltaic module 110 have a certain overlap width to achieve waterproof cooperation between the first beam 300 and the first photovoltaic module 110, without having the entire first folded edge 311 overlap the side of the first photovoltaic module 110.
[0055] Furthermore, during the installation of the first beam 300, the first beam 300 can be moved appropriately in the first direction to flexibly adjust the overlap width of the first folded edge 311 and the first photovoltaic module 110, thereby adjusting the relative position between the second sidewall 320 and the second photovoltaic module 120, ensuring that the second sidewall 320 achieves waterproof cooperation with the second photovoltaic module 120 through related structures. Based on this, the waterproof cooperation between the first beam 300 and the first photovoltaic module 110 and the second photovoltaic module 120 has lower requirements for the processing accuracy and installation accuracy of related structures, which is beneficial to improving the manufacturability of the photovoltaic system.
[0056] Furthermore, since the first folded edge 311 is connected to the first photovoltaic module 110 on the sun-facing side, it is convenient for operators to observe and operate, ensuring a reliable connection between the first folded edge 311 and the side of the first photovoltaic module 110, thereby ensuring the waterproof fit between the first beam 300 and the first photovoltaic module 110.
[0057] In this system, the first direction forms an angle with the horizontal plane. Thus, the first direction is the direction that is tilted relative to the horizontal plane, and it is also the direction that is tilted relative to the vertical direction. The second direction is the horizontal direction. In a photovoltaic system, the first direction is generally referred to as the vertical direction and the second direction as the horizontal direction. Both the first photovoltaic module 110 and the second photovoltaic module 120 are tilted relative to the horizontal plane, and one is located on top of the other.
[0058] Please see Figure 1 and Figure 10 In the second direction, the extension length of a single second photovoltaic module 120 is different from the extension length of a single first photovoltaic module 110, but is set to correspond to the length of a single first beam 300.
[0059] It is understood that the photovoltaic module has a frame 130 on its side, and the inner periphery of the frame 130 has a mounting groove for inserting the backsheet and protective panel of the photovoltaic module. Solar cells are sandwiched between the backsheet and the protective panel, with the backsheet located on the back-light side and the protective panel on the light-facing side. Thus, the frame 130 protrudes relative to the protective panel on the light-facing side and relative to the backsheet on the back-light side. Please refer to [further details omitted]. Figure 11 The border 130 includes a first frame strip 131 extending along a first direction and a second frame strip 132 extending along a second direction. Generally, the first frame strip 131 is referred to as a vertical frame strip, and the second frame strip 132 is referred to as a horizontal frame strip.
[0060] In this application, the first beam 300 and the second photovoltaic module 120 are arranged in a one-to-one correspondence. The length of the first beam 300 will match the length of the second frame strip 132 of the second photovoltaic module 120, but will not match the length of the second frame strip 132 of the first photovoltaic module 110, but will not interfere with the first frame strip 131 of the first photovoltaic module 110.
[0061] Specifically, in this application, such as Figure 11 As shown, the first beam 300 is covered by the second frame strip 132 of the first photovoltaic module 110 via a first folded edge 311. Even if the extension length of the first beam 300 and the extension length of the second frame strip 132 do not match, the ends of the first folded edge 311 and the first frame strip 131 will not interfere with each other. At the connection between the first frame strip 131 and the second frame strip 132, the first folded edge 311 can fit snugly with the first frame strip 131 without interfering with it. In this way, the first beam 300 can flexibly match the first photovoltaic modules 110 with different extension lengths via the first folded edge 311, allowing the photovoltaic system to arrange the photovoltaic modules more flexibly, making more efficient use of available area and maximizing the number of photovoltaic modules installed.
[0062] Furthermore, in this embodiment, as Figure 1 and Figure 10 As shown, the first photovoltaic module 110 and the second photovoltaic module 120 are configured as rectangular structures of the same size, with the second direction being the length direction of the first photovoltaic module 110 and the width direction of the second photovoltaic module 120, respectively.
[0063] That is, in this embodiment, photovoltaic modules of the same specification are arranged in a mixed manner of horizontal and vertical arrangement. Specifically, for the first photovoltaic module 110, its length direction and arrangement direction are both the second direction, which is a horizontal arrangement, i.e., a horizontal row; for the second photovoltaic module 120, its length direction is the first direction, which is the same as the vertical direction, which is a vertical arrangement, i.e., a vertical row.
[0064] This allows for more efficient use of available space, maximizing the number of photovoltaic modules installed. At the same time, standardized specifications for photovoltaic modules simplify supply chain management, reduce the variety and quantity of inventory, and facilitate stocking, replacement, and maintenance. Furthermore, the support system, installation method, and electrical connections for photovoltaic modules of the same specification can be standardized, which helps reduce on-site construction complexity and improve construction speed and consistency.
[0065] That is, for photovoltaic modules of the same specification, different installation directions can be adopted, so that the extension lengths of the first photovoltaic module 110 and the second photovoltaic module 120 in the second direction are different. When the length and width of the photovoltaic module are not integer multiples, the length of the first beam 300 will be set to correspond to the width of the photovoltaic module, so that the two ends of the first beam 300 can correspond to the two lateral sides of the second photovoltaic module 120, but cannot correspond to the two lateral sides of the first photovoltaic module 110. Thus, the first beam 300 needs to span the two first photovoltaic modules 110, and the first beam 300 can pass through, avoiding collisions with the two first photovoltaic modules 110.
[0066] In other embodiments, the first photovoltaic module 110 and the second photovoltaic module 120 may also be configured with different specifications, thereby having different extension lengths in the second direction.
[0067] In one implementation, such as Figure 1 and Figure 10 As shown, multiple first photovoltaic modules 110 and second photovoltaic modules 120 are distributed along the second direction. The photovoltaic system also includes a second beam 400, which extends along the first direction and has multiple beams distributed along the second direction. At least the second photovoltaic module 120 has a second beam 400 on its side. The second beam 400 forms a second water guide trough 410 extending along the first direction. The two ends of the first water guide trough 301 are respectively provided with two second water guide troughs 410.
[0068] Thus, the second beam 400 is set at least to correspond to the gap between two adjacent second photovoltaic modules 120, and the rainwater falling into this gap is collected by the second water guide channel 410, thereby further improving the waterproof performance of the photovoltaic system.
[0069] like Figure 1 and Figure 10 As shown, multiple first beams 300 are distributed along the first direction. The two ends of the first water guide channel 301 formed by each first beam 300 are respectively located above the two second water guide channels 410. In this way, the water flowing from the first water guide channel 301 can be received through the second water guide channel 410, so that the photovoltaic system can be drained from the outside through the second water guide channel 410.
[0070] Furthermore, a second beam 400 is provided on each side of the first photovoltaic module 110 and each side of the second photovoltaic module 120. It is understood that the gap between two adjacent first photovoltaic modules 110 and the gap between two adjacent second photovoltaic modules 120 do not coincide. In this embodiment, a second water channel 410 of a second beam 400 can be shared on the lateral sides of the first photovoltaic module 110 and the lateral sides of the second photovoltaic module 120, where adjacent sides of the two first photovoltaic modules 110 or the two second photovoltaic modules 120 are adjacent.
[0071] It is understandable that, since the first beam 300 and the second photovoltaic module 120 are set in a one-to-one correspondence, the end of the first water guide channel 301 will be opposite to the second water guide channel 410 set on the side of the second photovoltaic module 120. That is, the second water guide channel 410 set on the side of the first photovoltaic module 110 will not receive the drainage of the first water guide channel 301, but only undertake the drainage task of the vertical gap between the first photovoltaic modules 110. In this way, when the first photovoltaic module 110 is set as a horizontal photovoltaic module and the second photovoltaic module 120 is set as a vertical photovoltaic module, it is beneficial to increase the number of first beams 300, ensure the drainage efficiency of the photovoltaic system, and the vertical gaps that the first beams 300 need to cooperate with are relatively fewer, which is more conducive to ensuring the waterproof cooperation between the first beams 300 and the corresponding photovoltaic modules.
[0072] In one implementation, please refer to Figure 10 and Figure 11 The first photovoltaic module 110 and the second photovoltaic module 120 are distributed sequentially in a downward inclined direction. That is, taking the gap between the upper side of the first photovoltaic module 110 and the lower side of the second photovoltaic module 120 as an example, the first water guide channel 301 is used to receive rainwater falling into the gap and rainwater sliding down the sun-facing surface of the second photovoltaic module 120. At this time, since the first folded edge 311 is connected to the sun-facing side of the first photovoltaic module 110, the water will not penetrate through the gap between the first folded edge 311 and the first photovoltaic module 110 during the downward flow, which is beneficial to improving the waterproof cooperation effect between the first beam 300 and the first photovoltaic module 110. Furthermore, the frame of the second photovoltaic module 120 is installed inside the first water guide channel 301 to ensure the waterproof fit between the first beam 300 and the second photovoltaic module 120. This ensures that the first water guide channel 301 covers the lateral gap between the first photovoltaic module 110 and the second photovoltaic module 120, thereby ensuring the waterproof effect on the lateral gap.
[0073] In one implementation, please refer to Figures 11 to 14The photovoltaic system also includes a mounting bracket 610 and a locking component 620. The mounting bracket 610 is installed in the second water channel 410, and a locking component 620 is correspondingly installed on the mounting bracket 610. The locking component 620 forms a locking groove 621, and the side of the first photovoltaic module 110 is locked in the locking groove 621 of the locking component 620.
[0074] Thus, the engaging members 620 positioned at different locations can provide limiting functions for the first photovoltaic module 110 in multiple directions. First, after the side of the first photovoltaic module 110 is engaged in the slot 621 of the engaging member 620, the light-facing side and the back-facing side of the first photovoltaic module 110 will be clamped, which helps to ensure the installation stability of the first photovoltaic module 110. Second, when the two sides of the first photovoltaic module 110 in the length or width direction are engaged in the slots 621 of the two engaging members 620 respectively, the slots 621 of the two engaging members 620 should open towards each other, so that the first photovoltaic module 110 will be clamped between the two engaging members 620. Third, when the engaging member 620 is located between two adjacent first photovoltaic modules 110, both first photovoltaic modules 110 will be limited by the engaging member 620.
[0075] Furthermore, the first photovoltaic module 110 can also be supported by the second beam 400, which helps to ensure the installation stability of the first photovoltaic module 110. Especially when the first photovoltaic module 110 is installed horizontally, it helps to reduce the cantilever part of the first photovoltaic module 110 and avoid structural deformation caused by uneven stress on the first photovoltaic module 110.
[0076] The mounting bracket 610 and the locking member 620 are respectively provided with mounting holes for fasteners to pass through, so that the mounting bracket 610 and the locking member 620 are connected by fasteners. The mounting hole of at least one of the mounting bracket 610 and the locking member 620 is a strip hole extending along the first direction, so as to adjust the relative position of the locking member 620 and the mounting bracket 610 to ensure the installation stability of the first photovoltaic module 110.
[0077] In other embodiments, the engaging member 620 can also be directly installed inside the second water channel 410.
[0078] In one embodiment, the second sidewall 320 is provided with a reinforcing structure to improve the structural strength of the second sidewall 320 and ensure reliable cooperation between the second sidewall 320 and the corresponding photovoltaic module.
[0079] In one implementation, please refer to Figure 2The reinforcing structure includes a second folded edge 321, which is folded towards the first sidewall 310. This improves the overall rigidity and stability of the second sidewall 320, enabling it to better resist deformation under external forces and ensuring reliable cooperation between the second sidewall 320 and the corresponding photovoltaic module.
[0080] In one implementation, please refer to Figure 4 The reinforcing structure includes a reinforcing rolled edge 322, which is formed at the opening of the first water guide groove 301. The reinforcing rolled edge 322 not only increases the strength and durability of the edge of the second sidewall 320, but also reduces the sharpness of the edge of the second sidewall 320, improving the safety of disassembly and assembly operations and preventing accidental scratches.
[0081] In one implementation, please refer to Figure 6 The reinforcing structure includes at least one reinforcing rib 323 extending along the first direction. The reinforcing rib 323 can improve the bending resistance of the second sidewall 320 in the length direction, making the sidewall less prone to bending deformation due to heavy objects or external pressure, and effectively dispersing the load acting on the sidewall, reducing the possibility of failure due to local overload.
[0082] It is understood that the second sidewall 320 can be provided with one of the above-mentioned reinforcing structures, or it can be provided with a second folded edge 321 or a reinforcing rolled edge 322 while providing the reinforcing rib 323.
[0083] In one implementation, please refer to Figure 3 , Figure 5 , Figure 7 and Figure 9 The first folded edge 311 has a third folded edge 312 on the side away from the first sidewall 310. The third folded edge 312 is inclined towards the first photovoltaic module 110 in the direction away from the first folded edge 311. Both the first photovoltaic module 110 and the second photovoltaic module 120 have a frame 130. The frame 130 has a first abutment surface 111 and a second abutment surface 112 inclined relative to the first abutment surface 111 on the light-facing side. The first folded edge 311 covers the first abutment surface 111, and the third folded edge 312 covers the second abutment surface 112. The inclination angle of the third folded edge 312 relative to the first folded edge 311 matches the inclination angle of the second abutment surface 112 relative to the first abutment surface 111. In this way, the first folded edge 311 and the first abutment surface 111, and the third folded edge 312 and the second abutment surface 112 can have a relatively high degree of fit, which is beneficial to improving the connection stability between the first beam 300 and the first photovoltaic module 110 and the second photovoltaic module 120.
[0084] In one embodiment, the first folded edge 311 is connected to the first photovoltaic module 110 or the second photovoltaic module 120 by adhesive bonding. Adhesive bonding is relatively easy to operate, provides good fixation, and can improve the connection stability between the first beam 300 and the corresponding photovoltaic module, thereby ensuring waterproof cooperation between the first beam 300 and the corresponding photovoltaic module. Furthermore, when a third folded edge 312 is provided, the third folded edge 312 is also connected to the corresponding position of the corresponding photovoltaic module by adhesive bonding. Of course, in other embodiments, the first folded edge 311 can also be fixed to the frame 130 of the corresponding photovoltaic module by welding.
[0085] The above description is merely an exemplary embodiment of this application and does not limit the scope of protection of this application. Any equivalent structural transformations made based on the technical concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
