Description
Technical Field
[0001] This application relates to the field of photovoltaic power generation technology, and in particular to a component interconnection structure and a photovoltaic system. Background Technology
[0002] Photovoltaic modules are the core components of photovoltaic systems, converting solar energy into electrical energy to provide humanity with clean and renewable energy. Photovoltaic modules are typically composed of multiple solar cells connected in series or parallel and encapsulated together, featuring high photoelectric conversion efficiency and a long lifespan. Their surface is covered with high-strength glass and a waterproof backsheet, effectively protecting the cells from external environmental influences and ensuring stable operation under various climatic conditions.
[0003] Photovoltaic modules have a wide range of applications, including rooftops, ground-mounted photovoltaic stations, roadsides, and farmland. Taking rooftop photovoltaic modules as an example, many residential or commercial buildings have corrugated steel sheets on their roofs, and photovoltaic modules need to be installed on the surface of these sheets. However, since the surface of corrugated steel sheets is uneven, if the joint between two adjacent photovoltaic modules is located at the top of the concave part of the corrugated steel sheet, it will cause part of the structure of the two photovoltaic modules to be cantilevered. Since there is no support at the cantilevered part, it is easy to cause structural damage when maintenance personnel step on the cantilevered part of the photovoltaic module. Utility Model Content

[0052] Photovoltaic modules have a wide range of applications, including rooftops, ground-mounted photovoltaic stations, roadsides, and farmland. Taking rooftop photovoltaic modules as an example, many residential or commercial buildings have corrugated steel roofs, and photovoltaic modules need to be installed on these roofs. To increase their structural strength, corrugated steel roofs have concave and convex sections (corrugated structures) on their surface to distribute stress and facilitate drainage. However, because the surface of corrugated steel roofs is concave and convex, if the joint of two adjacent photovoltaic modules is located above the concave section of the corrugated steel roof, it will cause part of the structure of the two photovoltaic modules to be cantilevered. Since the cantilevered part has no support, it is prone to structural damage.
[0053] In practical use, maintenance personnel need to step on the top of the photovoltaic (PV) modules to perform routine maintenance and inspections. This includes checking the module surface for dust, dirt, obstructions, or other foreign objects; inspecting the module's connections and joints for looseness or damage; and checking for potential faults such as hot spots or microcracks within the module itself. Since some fault points may be located at the edges or seams of the module, maintenance personnel need to walk on the module surface for a more comprehensive inspection. However, if the cantilevered sections of the PV modules lack sufficient support, stepping on them could damage the module structure. Therefore, ensuring that the PV modules have sufficient strength and stability at cantilevered locations is crucial for the safe operation of the PV power plant.
[0054] To address the aforementioned problems, this application proposes a component interconnection structure 100 to solve the technical issues mentioned above.
[0055] Please see Figure 1 and combined Figure 3 In the technical solution of this application, the component interconnection structure 100 includes a first fixing member 1, a second fixing member 2, and an adjusting member 3. The first fixing member 1 is provided with a first connecting part 11 connected to the photovoltaic module 200. The second fixing member 2 is provided with a second connecting part 21 connected to another photovoltaic module 200. The second connecting part 21 is disposed opposite to the first connecting part 11. The adjusting member 3 is disposed through the first fixing member 1 and threadedly connected to the second fixing member 2, so as to adjust the distance between the first fixing member 1 and the second fixing member 2 by adjusting the adjusting member 3.
[0056] Understandably, in a photovoltaic system, two adjacent photovoltaic modules 200 are connected through a module interconnection structure 100. Specifically, a first fixing member 1 has a first connecting portion 11 facing one of the photovoltaic modules 200, and a second fixing member 2 has a second connecting portion 21 facing the other photovoltaic module 200. The first fixing member 1 and the second fixing member 2 are respectively connected to the two photovoltaic modules 200 for fixation, thereby making the two adjacent photovoltaic modules 200 form a whole. Furthermore, the first fixing member 1 and the second fixing member 2 are connected in series through an adjusting member 3. By adjusting the adjusting member 3, the relative position and distance between the first fixing member 1 and the second fixing member 2 can be adjusted, thereby allowing the module interconnection structure 100 to be adapted to photovoltaic module 200 products of different types, as well as photovoltaic module 200 products with different installation heights.
[0057] For different installation environments, the module interconnection structure 100 differs not only in its stress conditions but also in its structural design, material selection, installation method, and compatibility with the photovoltaic module 200. Therefore, this application proposes three different module interconnection structures 100:
[0058] Please refer to the first embodiment. Figure 1 , Figure 2 and combined Figure 3 ;
[0059] Please refer to the second embodiment. Figure 4 , Figure 5 and combined Figure 6 ;
[0060] Please refer to the third embodiment. Figure 7 , Figure 8 and combined Figure 9 .
[0061] The component interconnection structure 100 in the above three embodiments has been optimized for different application scenarios and can be adapted and selected according to the actual installation environment of the photovoltaic system and user needs.
[0062] In the embodiments provided in this application, a component interconnection structure 100 is provided at the joint between two adjacent photovoltaic modules 200. The component interconnection structure 100 is connected to the two adjacent photovoltaic modules 200 respectively through the first fixing member 1 and the second fixing member 2. This ensures that when the cantilever of the photovoltaic module 200 is subjected to vertical shear force, the component interconnection structure 100 can distribute the shear force to the two photovoltaic modules 200, and the two photovoltaic modules 200 share the force, thereby avoiding structural damage at the cantilever. Specifically, the component interconnection structure 100 includes a first fixing member 1, a second fixing member 2, and an adjusting member 3. The first fixing member 1 has a first connecting part 11 on one side for connecting to a photovoltaic module 200. The second fixing member 2 has a second connecting part 21 on the side opposite to the first connecting part 11 for connecting to another adjacent photovoltaic module 200. The adjusting member 3 connects the first fixing member 1 and the second fixing member 2 together, and the second fixing member 2 is threadedly connected to the adjusting member 3, allowing it to move up and down along the axial direction of the thread of the adjusting member 3, thereby adjusting the height difference between the first connecting part 11 and the second connecting part 21. This satisfies the connection of photovoltaic modules 200 of different heights or thicknesses and ensures reliable support at the cantilever.
[0063] Furthermore, by interconnecting adjacent photovoltaic modules 200, structural strength and overall integrity can be improved. This connection allows multiple photovoltaic modules 200 to share external forces when subjected to stress, thereby dispersing stress and preventing damage to individual modules due to excessive localized stress. Simultaneously, this connection method enhances the stability of the entire photovoltaic array, enabling it to better maintain structural integrity and functional stability when facing external environmental factors such as wind and snow loads. This significantly improves wind and pressure resistance, extends the service life of the photovoltaic modules 200, and ensures the long-term reliable operation of the photovoltaic system.
[0064] It should be noted that the first connecting part 11 and the second connecting part 21 are used to connect to two adjacent photovoltaic modules 200 respectively. The first connecting part 11 and the second connecting part 21 can be connected to the photovoltaic module 200 by snap-fit, threaded connection or adhesive connection. This application does not limit this.
[0065] First Embodiment
[0066] Please see Figure 1 , Figure 2 and combined Figure 3In the first embodiment proposed in this application, the first fixing member 1 includes a first horizontal plate 12 and two first vertical plates 13. The two first vertical plates 13 are spaced apart and connected by the first horizontal plate 12. The first horizontal plate 12 and the two first vertical plates 13 together form a U-shaped structure, and the first horizontal plate 12 and the two first vertical plates 13 enclose a receiving cavity 1b with the opening facing downward. The first horizontal plate 12 is provided with a mounting hole 121, and the adjusting member 3 is rotatably disposed in the mounting hole 121. The second fixing member 2 includes a frame 22 and a second vertical plate 23 connecting the frame 22. The frame 22 is located in the receiving cavity 1b, and the upper and lower ends of the frame 22 are provided with second connecting holes 221. The adjusting member 3 passes through the mounting hole 121 and is threadedly connected to the two second connecting holes 221. The first fixing member 1 adopts a U-shaped structure, composed of a first horizontal plate 12 and two first vertical plates 13. This structural design provides good integrity and stability, and can effectively disperse and withstand external forces from different directions. Meanwhile, the adjusting component 3 is threadedly connected to the frame 22 of the second fixing component 2, which not only enables flexible adjustment of the height position of the second fixing component 2 relative to the first fixing component 1, but also ensures the accuracy and reliability of the adjustment process. This allows it to adapt to height errors under different installation environments, ensuring that the photovoltaic module 200 has sufficient strength and stability in the cantilever position, while improving the flexibility and efficiency of installation. In addition, the design of the first fixing component 1 and the frame 22 fitting together enhances the deformation resistance of the entire module interconnection structure 100, making it more stable when facing external environmental factors such as wind loads and snow loads.
[0067] Please see Figure 2 The frame 22 and the second vertical plate 23 form a slot 2b at intervals. The first vertical plate 13, which is located closer to the second vertical plate 23, is accommodated in the slot 2b. The first vertical plate 13 can support the second vertical plate 23, thus avoiding the second vertical plate 23 from being easily broken due to single-point stress, and further improving the rationality of the structure.
[0068] During the adjustment of adjusting component 3, adjusting component 3 needs to rotate relative to the first fixed component 1. For details, please refer to further documentation. Figure 2 and combined Figure 3Therefore, the connecting rod 32 of the adjusting member 3 is divided into two sections, namely the first rod section 321 and the second rod section 322. The first rod section 321 is close to the adjusting head 31 and located inside the mounting hole 121. The outer peripheral surface of the first rod section 321 is a smooth surface, the mounting hole 121 is a through hole, and the outer diameter of the first rod section 321 is smaller than the inner diameter of the mounting hole 121, thereby ensuring that the adjusting member 3 can rotate relative to the first fixing member 1 without being restricted by the first fixing member 1. The outer circumferential surface of the second rod segment 322 of the connecting rod 32 is a threaded segment. It is threadedly connected to one or all of the second connecting holes 221 of the frame 22. When the adjusting member 3 rotates, it will drive the second fixing member 2 to move along the axial direction of the connecting rod 32. This allows the first fixing member 1 and the second fixing member 2 of the component interconnection structure 100 to effectively adapt to the height error of the photovoltaic module 200 during installation under different installation environments. This improves the connection strength and connection stability of the two connected photovoltaic modules 200 at the cantilever position, thereby extending the service life of the photovoltaic module 200 and ensuring the long-term reliable operation of the photovoltaic system.
[0069] In another alternative embodiment, the mounting hole 121 can also be designed as a through hole with internal threads. Correspondingly, the outer peripheral wall of the connecting rod 32 of the adjusting member 3 is provided with a fully threaded section. When installing the first fixing member 1 and the second fixing member 2, the first fixing member 1 and the second fixing member 2 are pre-fixed to the corresponding positions respectively, and then the adjusting member 3 is threadedly connected to the mounting hole 121 and one or all of the second connecting holes 221, thereby connecting and fixing the first fixing member 1 and the second fixing member 2 in series.
[0070] In this embodiment, to connect the first fixing member 1 and the second fixing member 2 to the photovoltaic module 200, a first support plate 15 and a first clamping plate 16 are provided on one side of the first vertical plate 13, and a second support plate 25 and a second clamping plate 26 are provided on one side of the second vertical plate 23. For more details, please refer to the following documentation. Figure 1 and combined Figure 3The first support plate 15, the first vertical plate 13, and the first clamping plate 16 form a first limiting groove 1a for engaging with the photovoltaic module 200. The second support plate 25, the second vertical plate 23, and the second clamping plate 26 form a second limiting groove 2a for engaging with another adjacent photovoltaic module 200. The first support plate 15 and the second support plate 25 are designed to be relatively long, thereby increasing the contact area with the bottom of the photovoltaic module 200 and providing stable support and a reliable connection interface for the photovoltaic module 200. The first support plate 15 and the second support plate 25 can fit tightly with the frameless photovoltaic module 200, ensuring that the photovoltaic module 200 will not be displaced or deformed due to external forces during installation. At the same time, the design of the first support plate 15 and the second support plate 25 increases the contact area and disperses stress, thereby improving the load-bearing capacity and stability of the entire module interconnection structure 100. This structure not only enhances the deformation resistance of the photovoltaic module 200 at the cantilever location, but also allows the module interconnection structure 100 to better adapt to photovoltaic modules 200 of different sizes and types, improving the versatility and compatibility of the module interconnection structure 100. Furthermore, the design of the first support plate 15 and the second support plate 25 facilitates installation and disassembly, simplifies the construction process, and reduces installation difficulty and cost.
[0071] To further optimize the overall structural strength of the first fastener 1, the first fastener 1 also includes two connecting crossbeams 18. For details, please refer to further documentation. Figure 2 The two ends of the connecting beam 18 are respectively connected to the two first vertical plates 13, and the two connecting beams 18 are located at the ends of the first vertical plates 13 away from the first horizontal plate 12. By setting two connecting beams 18, the first horizontal plate 12, the two first vertical plates 13 and the connecting beams 18 can jointly form a frame structure, further dispersing the stress on the first horizontal plate 12, so that the overall structural strength of the first fastener 1 is improved.
[0072] Second Embodiment
[0073] Please see Figure 4 , Figure 5 and combined Figure 6In the second embodiment proposed in this application, the first fixing member 1 includes a first horizontal plate 12 and a first vertical plate 13 connected to each other. The first horizontal plate 12 and the first vertical plate 13 are arranged at an angle, and the first fixing member 1 is generally L-shaped. The first horizontal plate 12 is provided with a first connecting hole 122. The frame 22 of the second fixing member 2 is provided with two oppositely arranged second connecting holes 221, and the two second connecting holes 221 are concentrically arranged. The adjusting member 3 is sequentially threaded to the first connecting hole 122 and one or all of the second connecting holes 221. When it is necessary to adjust the height difference between the first fixing member 1 and the second fixing member 2, the adjusting member 3 needs to be removed first, then the first fixing member 1 and the second fixing member 2 need to be moved to the ideal position, and finally the adjusting member 3 is passed through the first connecting hole 122 and the second connecting hole 221 to form a fixation, thereby realizing the adjustment of the height difference between the first fixing member 1 and the second fixing member 2. This design not only effectively solves the problem of module cantilever caused by the mismatch between the size of the photovoltaic module 200 and the size of the color steel tile 300, but also ensures that the photovoltaic module 200 has sufficient strength and stability at the cantilever position to adapt to different installation environments and user needs.
[0074] Please refer to further information. Figure 5 and Figure 6 The first horizontal plate 12, the first vertical plate 13, and the bracket 14 form an installation notch 1c. In actual installation, part of the second fixing member 2 is pre-installed into the installation notch 1c of the first fixing member 1. At this time, the first fixing member 1 and the second fixing member 2 can move up and down relative to each other. Then, the first fixing member 1 and the second fixing member 2 are respectively snapped into two adjacent photovoltaic modules 200. The first fixing member 1 and the second fixing member 2 are slid into the preset position. Finally, the adjusting member 3 is used to pass through the first connecting hole 122 and the second connecting hole 221 in sequence, so as to be threadedly connected and fixed to the first fixing member 1 and the second fixing member 2 respectively, thereby ensuring that the two adjacent photovoltaic modules 200 are connected into one unit through the module interconnection structure 100, and the two adjacent photovoltaic modules 200 jointly bear the shear force from the top.
[0075] Optionally, the first connecting hole 122 can also be designed as a through hole with a smooth inner wall surface. Correspondingly, the end of the connecting rod 32 of the adjusting member 3 near the adjusting head 31 is designed as a smooth rod, so that when the adjusting member 3 is inserted into the first fixing member 1, it can rotate relative to the first fixing member 1. When the adjusting member 3 rotates, since the second fixing member 2 is threadedly connected to the adjusting member 3, the second fixing member 2 will move along the axial direction of the adjusting member 3, so as to realize the adjustment of the height difference between the first fixing member 1 and the second fixing member 2.
[0076] To facilitate adjustment of the adjustment component 3 by maintenance personnel, the adjustment component 3 includes an adjustment head 31 and a connecting rod 32. For details, please refer to the following document. Figure 5The adjusting head 31 is also known as the bolt head, and the connecting rod 32 is also known as the screw. The adjusting head 31 and the connecting rod 32 are integrated structures. The side of the adjusting head 31 facing away from the connecting rod 32 is provided with a groove for matching disassembly and assembly tools, such as a cross groove or a flat groove. By inserting disassembly and assembly tools such as an Allen wrench or a screwdriver into the groove that matches its shape, the adjusting component 3 can be rotated, thereby adjusting the distance between the first fixing component 1 and the second fixing component 2.
[0077] Optionally, to further enhance the structural strength of the first fastener 1, a bracket 14 is also provided between the first horizontal plate 12 and the first vertical plate 13. For details, please refer to further reference. Figure 5 The bracket 14 can be a triangular bracket or an L-shaped bracket; this application does not limit this. In one embodiment of this application, the bracket 14 is an L-shaped bracket, with its two ends connected to the end of the first horizontal plate 12 away from the first vertical plate 13 and the end of the first vertical plate 13 away from the first horizontal plate 12, respectively. This effectively prevents the first horizontal plate 12 and the first vertical plate 13 from deforming or displacing under stress, thereby ensuring the robustness and reliability of the entire module interconnection structure 100. Especially during the installation of the photovoltaic module 200, it may be affected by various external forces, such as wind loads and operating forces during installation. The L-shaped bracket can provide additional support for the first fixing member 1, enabling it to remain stable under these complex working conditions and significantly improving the performance of the module interconnection structure 100.
[0078] In this embodiment, to match the protruding shape of the frame 210 of the photovoltaic module 200, two first extension plates 17 are provided on the side of the first vertical plate 13 facing away from the first horizontal plate 12, and two second extension plates 27 are provided on the side of the frame 22 facing away from the first vertical plate 13. For details, please refer to further reading. Figure 5 The first limiting groove 1a includes a first groove segment 1a1 and two second groove segments 1a2 connected to the first groove segment 1a1. The two second groove segments 1a2 are respectively disposed on the two first extension plates 17 and face each other. The first groove segment 1a1 is a groove for accommodating the photovoltaic module 200, and the two second groove segments 1a2 respectively accommodate the upper and lower ends of the frame 210. In actual installation, the first fixing member 1 is slid in from one side of the frame 210, so that the upper and lower ends of the frame 210 are respectively accommodated in the two second groove segments 1a2, thus achieving a reliable snap-fit. The second limiting groove 2a of the second fixing member 2 includes a third groove segment 2a1 and two fourth groove segments 2a2. The two fourth groove segments 2a2 are respectively disposed on the two second extension plates 27 and face each other. The upper and lower ends of the frame 210 of another adjacent photovoltaic module 200 are respectively accommodated in the fourth groove segments 2a2. Since the installation method of the second fixing member 2 and the photovoltaic module 200 is the same as that of the first fixing member 1, it will not be described again here.
[0079] Third Embodiment
[0080] Please see Figure 7 , Figure 8 and combined Figure 9 In the third embodiment of this application, the structure of the first fixing member 1 and the second fixing member 2 is further simplified. Specifically, the first fixing member 1 includes a first horizontal plate 12 and a first vertical plate 13 connected together, and the second fixing member 2 includes a second horizontal plate 24 and a second vertical plate 23 connected together. It should be noted that the included angle between the first horizontal plate 12 and the first vertical plate 13 can be an acute angle or a right angle. The included angle between the first horizontal plate 12 and the first vertical plate 13 can be designed according to the installation requirements to facilitate the installation of the adjusting member 3. In this embodiment, the first horizontal plate 12 and the first vertical plate 13 are arranged perpendicularly. Similarly, the second horizontal plate 24 and the second vertical plate 23 are also arranged perpendicularly. For the installation of the adjusting member 3, the first horizontal plate 12 is provided with a first connecting hole 122, and the second horizontal plate 24 is provided with a second connecting hole 221. It should be noted that the adjusting member 3 can be threadedly connected to the first connecting hole 122 and rotatably connected to the second connecting hole 221, or it can be threadedly connected to both the first connecting hole 122 and the second connecting hole 221. That is, the second connecting hole 221 can be a through hole with a smooth inner wall surface or a threaded hole. This application does not limit this. In an optional embodiment of this invention, both the first connecting hole 122 and the second connecting hole 221 are threaded holes, so that the adjusting member 3 is threadedly connected to the first horizontal plate 12 and the second horizontal plate 24 respectively, thereby improving the reliability of the connection.
[0081] In this embodiment, both the first fixing member 1 and the second fixing member 2 are horizontally arranged T-shaped structures, which significantly simplifies the overall structure and reduces manufacturing costs and installation complexity. The T-shaped first fixing member 1 and the second fixing member 2 provide stable support and connection points through the vertically arranged first horizontal plate 12, first vertical plate 13, second horizontal plate 24, and second vertical plate 23, while maintaining sufficient strength and stability. By providing first connecting holes 122 and second connecting holes 221 on the first horizontal plate 12 and the second horizontal plate 24 respectively, and using the adjusting member 3 for threaded connection, this design not only realizes the height difference adjustment function of the first fixing member 1 and the second fixing member 2, but also ensures the firmness and reliability of the connection. This simplified structure reduces the number of parts while ensuring functionality, improves installation efficiency, and is particularly suitable for large-scale photovoltaic module 200 installation scenarios. It can quickly achieve interconnection between photovoltaic modules 200, while adapting to height errors in different installation environments of photovoltaic modules 200, ensuring the stable operation of the photovoltaic system.
[0082] To match the protruding shape of the frame 210 of the photovoltaic module 200, two first extension plates 17 are provided on the side of the first vertical plate 13 facing away from the first horizontal plate 12, and two second extension plates 27 are provided on the side of the second vertical plate 23 facing away from the second horizontal plate 24. For details, please refer to further reference. Figure 5 The first limiting groove 1a includes a first groove segment 1a1 and two second groove segments 1a2 connected to the first groove segment 1a1. The two second groove segments 1a2 are respectively disposed on the two first extension plates 17 and face each other. The first groove segment 1a1 is a groove for accommodating the photovoltaic module 200, and the two second groove segments 1a2 respectively accommodate the upper and lower ends of the frame 210. In actual installation, the first fixing member 1 is slid in from one side of the frame 210, so that the upper and lower ends of the frame 210 are respectively accommodated in the two second groove segments 1a2, thus achieving a reliable snap-fit. The second limiting groove 2a of the second fixing member 2 includes a third groove segment 2a1 and two fourth groove segments 2a2. The two fourth groove segments 2a2 are respectively disposed on the two second extension plates 27 and face each other. The upper and lower ends of the frame 210 of another adjacent photovoltaic module 200 are respectively accommodated in the fourth groove segments 2a2. Since the installation method of the second fixing member 2 and the photovoltaic module 200 is the same as that of the first fixing member 1, it will not be described again here.
[0083] Furthermore, the first horizontal plate 12 and the first vertical plate 13, as well as the second horizontal plate 24 and the second vertical plate 23, are all integral structures made of stainless steel. This integral structure improves the overall strength and stability of the first fixing member 1 and the second fixing member 2, reducing potential structural weaknesses caused by connection points or welds, making the first fixing member 1 and the second fixing member 2 more robust and durable. The use of stainless steel provides the component interconnection structure 100 with excellent corrosion resistance and oxidation resistance, enabling it to operate stably for extended periods in various harsh natural environments, effectively extending the service life of the components and reducing maintenance costs. In addition, stainless steel has good mechanical and processing properties, facilitating the manufacture and processing into complex shapes while ensuring dimensional accuracy, further enhancing the reliability and adaptability of the component interconnection structure 100, allowing it to better meet different installation environments and usage requirements.
[0084] To prevent the adjusting member 3 from becoming loose, in one embodiment of this application, a shim 4 is provided between the adjusting head 31 and the first horizontal plate 12. For details, please refer to further details. Figure 8 and Figure 9The shim 4 effectively prevents the adjusting component 3 from loosening due to vibration or external forces during use. By increasing the contact area and providing additional friction, it enhances the connection stability between the adjusting component 3 and the second horizontal plate 24. This design not only improves the reliability of the module interconnection structure 100 during long-term use but also reduces problems such as loose connections and structural deformation of the photovoltaic module 200 that may result from loose adjusting component 3, thereby ensuring the safe operation of the photovoltaic system. At the same time, the use of the shim 4 facilitates fine-tuning during installation, further improving the flexibility and precision of the installation.
[0085] This application also proposes a photovoltaic system, which is generally installed on a corrugated steel sheet 300. The photovoltaic system includes multiple photovoltaic modules 200 and a module interconnection structure 100 as described above. The multiple photovoltaic modules 200 are arranged in an array, and each pair of adjacent photovoltaic modules 200 is connected through the module interconnection structure 100. The photovoltaic modules 200 can be frameless photovoltaic modules. Please refer to [link to relevant documentation]. Figure 3 It can also be a framed photovoltaic module; please refer to [link / reference]. Figure 6 or Figure 9 Taking a framed photovoltaic module as an example, the frame 210 protrudes from the photovoltaic module 200, and the upper and lower ends of the frame 210 are respectively snapped and fixed to the first extension plate 17 or the second extension plate 27 to achieve reliable interconnection. It should be noted that one or more interconnection structures 100 can be provided between each pair of adjacent photovoltaic modules 200. This application does not limit this, and the specific arrangement can be adaptively adjusted according to multiple factors such as the size and weight of the photovoltaic module 200, the complexity of the installation environment, and the arrangement of the photovoltaic modules 200. For example, when the photovoltaic module 200 is heavy or the wind force in the application scenario is high, multiple interconnection structures 100 can be considered to ensure uniform stress distribution. The specific structure of the interconnection structure 100 is as described in the above embodiments. Since this photovoltaic system adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought by the technical solutions of the above embodiments, which will not be elaborated further here.
