Description

Technical Field

[0001] This application belongs to the field of photovoltaic technology, and in particular relates to a flexible photovoltaic bracket and a photovoltaic system. Background Technology

[0002] Prestressed cable-stayed flexible photovoltaic (PV) support systems are widely used in PV systems and have broad application prospects. However, in related technologies, the cables of double-layer cable-stayed flexible supports typically employ planar or spatial support structures. Planar support structures lack stability, and the support structure is prone to tilting or displacement when installing and tensioning the lower layer of cables. Spatial support structures can solve the problem of tilting or displacement caused by the installation and tensioning of the lower layer of cables, but at the same time, the connection nodes of the cable-stayed support structures are complex, leading to an increase in on-site installation workload, indicating room for improvement. Utility Model Content

[0003] This application aims to at least address the technical problem in related technologies where it is difficult to balance the stability of the support connection structure between cables in a double-layer cable flexible support system with the workload of installation. To this end, this application proposes a flexible photovoltaic support system and photovoltaic system that can simplify the connection form of the inter-group connection structure while maintaining stability.

[0004] In a first aspect, this application provides a flexible photovoltaic support structure, comprising:

[0005] Multiple sets of photovoltaic support structures are distributed at intervals along a first direction, including load-bearing cables and component cables extending along a second direction. The photovoltaic support structure has at least one set of a first node provided on the load-bearing cable, a second node provided on the component cable, and a third node provided on the component cable. The first node and the second node in the same set are arranged opposite each other vertically, and the second node and the third node in the same set are spaced apart along the second direction.

[0006] The inter-group connection structure includes multiple connectors connecting the first node, the second node, and the third node.

[0007] In the above technical solution, by simplifying the connection form of the inter-group connection structure, the amount of on-site installation work can be reduced. At the same time, the inter-group connection structure is distributed in two mutually perpendicular planes, which can improve the stability of the inter-group connection structure, thereby improving the structural stability of the flexible photovoltaic support wind-resistant system.

[0008] According to one embodiment of this application, the inter-group connection structure includes a first connector and a second connector, wherein the first connector is connected between the first node and the second node in the same group, and the second connector is connected between the second node and the third node in the same group.

[0009] In the above technical solution, through the synergistic effect of the first connector and the second connector, the inter-group connection structure connects the load-bearing cable and the component cable of the photovoltaic support structure together, which can improve the stability of the flexible photovoltaic bracket.

[0010] According to one embodiment of this application, the inter-group connection structure further includes a third connector that extends along the first direction and connects between the first nodes of the plurality of photovoltaic support structures.

[0011] In the above technical solution, the third connector can form a preliminary stable support network by connecting the first nodes of multiple sets of photovoltaic support structures, which helps to resist the influence of loads and wind from different directions and maintain the safety and stability of the flexible photovoltaic support under complex environmental conditions.

[0012] According to one embodiment of this application, the inter-group connection structure further includes a fourth connector, wherein the first node is connected to the closest second node in the adjacent photovoltaic support structure via the fourth connector.

[0013] In the above technical solution, the fourth connector can increase the overall stiffness of the flexible photovoltaic support system, and also help to optimize the stress distribution of the entire system, reduce the deformation and displacement of the flexible photovoltaic support under external loads, and improve the durability of the flexible photovoltaic support.

[0014] According to one embodiment of this application, a plurality of fourth connectors connecting adjacent photovoltaic support structures are arranged crosswise.

[0015] In the above technical solution, the cross-connected fourth connectors can form a more stable support system by connecting adjacent photovoltaic support structures, which helps to resist external loads and wind effects, and improves the safety and stability of the flexible photovoltaic bracket under harsh environmental conditions.

[0016] According to one embodiment of this application, the photovoltaic support structure further includes a support frame and a stabilizing cable 2-3, wherein the stabilizing cable is connected between the first node closest to the support frame and the support frame.

[0017] In the above technical solution, the stabilizing cable, by connecting the nodes on the support frame and the load-bearing cable, can form a more stable support network, which helps to resist the influence of external loads and wind, and improves the safety and stability of the flexible photovoltaic support. Under the action of wind, the stabilizing cable can reduce the swaying and displacement of the flexible photovoltaic support, thereby reducing the risk of damage caused by wind load.

[0018] According to one embodiment of this application, the third node in the same group is located on the same side of the second node.

[0019] In the above technical solution, the third node in the same group is located on the same side of the second node, which can optimize the stress distribution of the entire structure, transfer some of the load to a more stable area, thereby reducing the burden on a single node and helping to enhance the stability and efficiency of the photovoltaic support structure.

[0020] According to one embodiment of this application, the inter-group connection structure is one of steel profiles, wire ropes, and steel strands.

[0021] In the above technical solutions, structural steel, wire rope and steel strand all have important application value in the inter-group connection structure of the photovoltaic support structure. Each has unique characteristics and application scenarios, and can be selected and applied according to specific needs.

[0022] According to one embodiment of this application, the flexible photovoltaic support also includes:

[0023] A wind-resistant device, comprising a first wind-resistant cable, a second wind-resistant cable, a limiting member, and a pile foundation, wherein the first wind-resistant cable is connected between the first node of the outermost photovoltaic support structure and the limiting member, and the second wind-resistant cable is connected between the second node of the outermost photovoltaic support structure and the limiting member.

[0024] In the above technical solution, by reasonably designing the wind-resistant device, the overall stability and safety of the flexible photovoltaic support can be improved, the component damage and maintenance costs caused by wind can be reduced, and the service life of the flexible photovoltaic support can be extended.

[0025] Secondly, this application provides a photovoltaic system, comprising:

[0026] Flexible photovoltaic brackets as described in any one of the above statements.

[0027] Photovoltaic modules are installed on the photovoltaic support structure.

[0028] In the above technical solution, the photovoltaic system can convert solar energy into electrical energy through the joint cooperation of the flexible photovoltaic support and the photovoltaic module. The flexibility and stability of the flexible photovoltaic support can provide reliable support and protection for the photovoltaic module.

[0044] The embodiments of this application are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this application, and should not be construed as limiting this application.

[0045] This application aims to at least address the technical problem in related technologies where it is difficult to balance the stability of the support connection structure between cables in a double-layer cable flexible support system with the workload of installation. To this end, this application proposes a flexible photovoltaic support system and photovoltaic system that can simplify the connection form of the inter-group connection structure while maintaining stability.

[0046] The following is for reference. Figures 1-5 A flexible photovoltaic support 10 according to an embodiment of this application is described.

[0047] like Figure 1 As shown, the flexible photovoltaic support 10 includes an inter-group connection structure 120 and multiple photovoltaic support structures 110, and the multiple photovoltaic support structures 110 are distributed at intervals along the first direction X to form an orderly and stable support network.

[0048] The photovoltaic support structure 110 includes a load-bearing cable 112 and a module cable 111 extending along the second direction Y. The photovoltaic support structure 110 has at least one set of a first node 115 on the load-bearing cable 112, a second node 116 on the module cable 111, and a third node 117 on the module cable 111. The first node 115 and the second node 116 in the same set are arranged vertically opposite each other, and the second node 116 and the third node 117 in the same set are spaced apart along the second direction Y.

[0049] The photovoltaic support structure 110 is the core part of the flexible photovoltaic bracket 10. It is mainly composed of load-bearing cable 112 and component cable 111. Both the load-bearing cable 112 and the component cable 111 extend along the second direction Y. The second direction Y is the length direction of the photovoltaic support structure 110. The first direction X is perpendicular to the second direction Y.

[0050] The load-bearing cable 112 serves as the main load-bearing structure, responsible for supporting the weight of the photovoltaic module 20. The module cable 111 is used to fix and support the photovoltaic module 20. The load-bearing cable 112 and the module cable 111 have good strength and corrosion resistance to adapt to harsh outdoor environmental conditions and maintain the long-term stability and safety of the flexible photovoltaic support 10.

[0051] The photovoltaic support structure 110 also includes at least one set of first node 115, second node 116 and third node 117. The photovoltaic support structure 110 and the inter-group connection structure 120 are connected at each node. The first node 115 is located on the load-bearing cable 112, and the second node 116 and the third node 117 are both located on the component cable 111. The second node 116 and the first node 115 of the same group are arranged vertically opposite each other, and the third node 117 of the same group is spaced apart from the second node 116 along the second direction Y.

[0052] The inter-group connection structure 120 is a key part that connects the various photovoltaic support structures 110. It mainly consists of multiple connectors, which are respectively connected between the first node 115, the second node 116 and the third node 117. This connection method can enhance the stability of the flexible photovoltaic bracket 10 to maximize the absorption efficiency of solar energy.

[0053] Furthermore, specifically, taking the same group of first node 115, second node 116 and third node 117 as an example, the connectors connecting the first node 115 and second node 116 and the first node 115 and third node 117 can be regarded as planar structures. The connectors connecting different first nodes 115 and the connectors connecting the first node 115 and the closest second node 116 in the adjacent photovoltaic support structure 110 can also be regarded as planar structures, and the two planes are perpendicular to each other, thereby improving the stability of the inter-group connection structure 120.

[0054] The prestressed cable-stayed flexible photovoltaic support system 10 is widely used in photovoltaic systems 1 and has broad application prospects. However, the inventors have found that the cables of the double-layer cable flexible support system in related technologies usually adopt planar or spatial support connection structures. The planar support connection structure lacks stability and is prone to tilting and deviating when installing and tensioning the lower layer cables. The spatial support connection structure can solve the problem of tilting and deviating of the support structure caused by installing and tensioning the lower layer cables, but at the same time, the connection nodes of the cable support connection structure are complex, which increases the workload of on-site installation and there is room for improvement.

[0055] Based on the above considerations, in order to solve the problem of balancing the stability of the support connection structure between the cables of the double-layer cable flexible bracket and the installation workload, the inventors, after in-depth research, designed a flexible photovoltaic bracket 10. In this flexible photovoltaic bracket 10, the inter-group connection structure 120 is distributed in two mutually perpendicular planes, which can simplify the connection form of the inter-group connection structure 120 while maintaining stability.

[0056] According to the flexible photovoltaic support 10 provided in the embodiments of this application, by simplifying the connection form of the inter-group connection structure 120, the amount of on-site installation work can be reduced. At the same time, the inter-group connection structure 120 is distributed in two mutually perpendicular planes, which can improve the stability of the inter-group connection structure 120, thereby improving the structural stability of the wind-resistant system of the flexible photovoltaic support 10.

[0057] In some embodiments, such as Figure 1 and Figure 2As shown, the inter-group connection structure 120 includes a first connector 121 and a second connector 122. The first connector 121 is connected between the first node 115 and the second node 116 in the same group, and the second connector 122 is connected between the second node 116 and the third node 117 in the same group.

[0058] The inter-group connection structure 120 is a key part that connects the various photovoltaic support structures 110. It is mainly composed of multiple connectors, which are respectively connected between the first node 115, the second node 116 and the third node 117. This connection method can enhance the stability of the flexible photovoltaic bracket 10.

[0059] Specifically, the first connector 121 is connected between the first node 115 and the second node 116 in the same group. The first node 115 is located on the load-bearing cable 112, while the second node 116 is located on the component cable 111. The two are arranged vertically opposite each other. The first connector 121 can connect the load-bearing cable 112 and the component cable 111 in the vertical direction, and transfer the weight and load from the photovoltaic module 20 to the load-bearing cable 112, thereby maintaining the vertical stability of the flexible photovoltaic support 10.

[0060] The second connector 122 is connected between the second node 116 and the third node 117 in the same group. The second node 116 and the third node 117 are both located on the component cable 111 and are spaced apart along the second direction Y. The second connector 122 mainly maintains the stability of the flexible photovoltaic support 10 in the horizontal direction.

[0061] It is understandable that, through the synergistic effect of the first connector 121 and the second connector 122, the inter-group connection structure 120 connects the load-bearing cable 112 and the component cable 111 of the photovoltaic support structure 110 together, which can improve the stability of the flexible photovoltaic bracket 10.

[0062] In some embodiments, such as Figure 1 and Figure 2 As shown, the inter-group connection structure 120 also includes a third connector 123, which extends along the first direction X and connects between the first nodes 115 of the multiple photovoltaic support structures 110.

[0063] The inter-group connection structure 120 is a key part that connects the various photovoltaic support structures 110. It is mainly composed of multiple connectors, which are respectively connected between the first node 115, the second node 116 and the third node 117. This connection method can enhance the stability of the flexible photovoltaic bracket 10.

[0064] Specifically, the third connector 123 is connected between the first nodes 115 of the multiple photovoltaic support structures 110. The first nodes 115 are located on the load-bearing cable 112. The third connector 123 can establish a connection between the multiple photovoltaic support structures 110. The third connector 123 extends along the first direction X, that is, it is perpendicular to the second direction Y of the extension of the load-bearing cable 112 and the component cable 111 in the photovoltaic support structure 110. This design enables the third connector 123 to connect each photovoltaic support structure 110, thereby enhancing the stability and continuity of the overall structure.

[0065] Understandably, the third connector 123, by connecting the first nodes 115 of multiple photovoltaic support structures 110, can form a preliminary stable support network, which helps to resist the impact of loads and wind from different directions and maintain the safety and stability of the flexible photovoltaic bracket 10 under complex environmental conditions.

[0066] In some embodiments, such as Figure 1 and Figure 2 As shown, the inter-group connection structure 120 also includes a fourth connector 124, which connects the first node 115 to the closest second node 116 in the adjacent photovoltaic support structure 110.

[0067] The inter-group connection structure 120 is a key part that connects the various photovoltaic support structures 110. It is mainly composed of multiple connectors, which are respectively connected between the first node 115, the second node 116 and the third node 117. This connection method can enhance the stability of the flexible photovoltaic bracket 10.

[0068] Specifically, the fourth connector 124 is connected between the first node 115 and the second node 116 of the adjacent photovoltaic support structure 110 that is closest to the first node 115. There are two sets of photovoltaic support structures 110 adjacent to the first node 115, and two fourth connectors 124 are also provided accordingly. That is, one first node 115 is connected to two fourth connectors 124, and they extend in opposite directions. This connection method can form a cross support effect, which can strengthen the connection between the load-bearing cable 112 and the component cable 111 in different groups.

[0069] The fourth connector 124 connects the first node 115 to the second node 116 of the adjacent photovoltaic support structure 110, forming a more stable support network. This connection method helps to resist external loads from different directions, thereby improving the safety and stability of the flexible photovoltaic bracket 10 under complex environmental conditions.

[0070] Understandably, the fourth connector 124 can increase the overall stiffness of the flexible photovoltaic support 10 system, and also help optimize the stress distribution of the entire system, reduce the deformation and displacement of the flexible photovoltaic support 10 under external loads, and improve the durability of the flexible photovoltaic support 10.

[0071] In some embodiments, such as Figure 1 and Figure 2 As shown, multiple fourth connectors 124 are arranged crosswise between adjacent photovoltaic support structures 110.

[0072] The fourth connector 124 is connected between the first node 115 and the second node 116 of the adjacent photovoltaic support structure 110 that is closest to the first node 115. The first nodes 115 of the two adjacent photovoltaic support structures 110 are respectively connected to two fourth connectors 124. The two fourth connectors 124 are intersected between the two adjacent photovoltaic support structures 110 to form a complex support network. This layout can strengthen the connection between the load-bearing cable 112 and the module cable 111 of the two adjacent photovoltaic support structures 110, and significantly enhance the interaction and stability between the adjacent photovoltaic support structures 110.

[0073] The cross-layout also allows the fourth connector 124 to more effectively disperse and transfer the load, transferring part of the load to the adjacent support structure, which can improve the load-bearing capacity and stability of the entire system. At the same time, under the action of wind, the cross-layout fourth connector 124 can effectively resist the impact and displacement of wind load on the flexible photovoltaic bracket 10.

[0074] Understandably, the cross-connecting fourth connector 124, by connecting adjacent photovoltaic support structures 110, can form a more stable support system, which helps to resist external loads and wind effects, and improves the safety and stability of the flexible photovoltaic bracket 10 under harsh environmental conditions.

[0075] In some embodiments, such as Figure 3 and Figure 4 As shown, the photovoltaic support structure 110 also includes a support frame 114 and a stabilizing cable 113, with the stabilizing cable 113 connecting the first node 115 closest to the support frame 114 and the support frame 114.

[0076] The support frame 114 is the end part of both ends of the photovoltaic support structure 110, which is used to provide a stable support platform. The component cable 111, load-bearing cable 112 and stabilizing cable 113 of the photovoltaic support structure 110 are all fixed to the support frame 114 at both ends. The bottom of the support frame 114 extends into the ground, which can support the weight of the photovoltaic module 20 and bear external loads. The support frame 114 can be made of aluminum alloy or steel, etc. These materials have excellent mechanical properties and corrosion resistance, and can adapt to various complex environmental conditions.

[0077] Each photovoltaic support structure 110 has a support frame 114 at both ends. The two ends of the component cable 111 and the load-bearing cable 112 in the same group are connected to the top of different support frames 114 respectively. The stabilizing cable 113 is connected between the support frame 114 and the first node 115 closest to the support frame 114. Its main function is to enhance the stability of the entire photovoltaic support structure 110 and reduce the risk of displacement or deformation under the action of wind or other external forces. The stabilizing cable 113 is usually made of high-strength and corrosion-resistant materials, such as steel wire rope or synthetic fiber cable.

[0078] Understandably, the stabilizing cable 113, by connecting the nodes on the support frame 114 and the load-bearing cable 112, can form a more stable support network, which helps to resist the influence of external loads and wind, and improves the safety and stability of the flexible photovoltaic support 10. Under the action of wind, the stabilizing cable 113 can reduce the swaying and displacement of the flexible photovoltaic support 10, thereby reducing the risk of damage caused by wind load.

[0079] In some embodiments, such as Figure 3 and Figure 4 As shown, the third node 117 in the same group is located on the same side as the second node 116.

[0080] The first node 115 is located on the load-bearing cable 112, and the second node 116 and the third node 117 are both located on the component cable 111 and are spaced apart along the second direction Y. The first node 115, the second node 116 and the third node 117 together constitute the photovoltaic support structure 110. Multiple sets of first nodes 115, second nodes 116 and third nodes 117 are spaced apart along the first direction X. The second nodes 116 and third nodes 117 in the same set are spaced apart along the second direction Y and are located on the same side of the second node 116. That is, the second connector 122 is located on the same side of the second node 116. This layout helps to optimize stress distribution and enhance the overall stiffness of the structure.

[0081] For example, such as Figure 4 As shown, the third node 117 in the same group is located on the same side of the second node 116, while this side is the side that faces the second node 116 in a different group along the second direction Y.

[0082] Understandably, the third node 117 in the same group is located on the same side as the second node 116, which can optimize the stress distribution of the entire structure, transfer some of the load to a more stable area, thereby reducing the burden on a single node and helping to enhance the stability and efficiency of the photovoltaic support structure 110.

[0083] In some embodiments, the inter-group connection structure 120 is one of steel profiles, wire ropes, and steel strands.

[0084] Section steel is a type of steel with a specific cross-sectional shape and size. It is widely used in building and engineering structures. Section steel has high strength and rigidity and can withstand large loads. Section steel can also be processed and assembled by cutting, welding or bolting.

[0085] A wire rope is a type of rope made of multiple strands of steel wire twisted together. It has high strength and excellent flexibility. Wire rope can withstand large tensile forces and can adapt to various complex shapes and angles, making it convenient for connection and fixation.

[0086] Steel strand is a steel product made of multiple steel wires twisted together. It has high tensile strength and can withstand large loads. At the same time, steel strand has a compact structure, occupies little space, and is convenient for installation and layout.

[0087] For example, the component cable 111, load-bearing cable 112 and stabilizing cable 113 in the photovoltaic support structure 110 can be made of flexible materials such as steel wire rope or steel strand, and the inter-module connection structure 120 can be made of rigid materials such as steel sections or flexible materials such as steel wire rope or steel strand, depending on the actual application requirements.

[0088] It is understandable that structural steel, wire rope, and steel strand all have important application value in the inter-group connection structure 120 of the photovoltaic support structure 110. Each has unique characteristics and application scenarios, and can be selected and applied according to specific needs.

[0089] In some embodiments, such as Figure 1 and Figure 2 As shown, the flexible photovoltaic support 10 also includes a wind-resistant device 130. The wind-resistant device 130 includes a first wind-resistant cable 131, a second wind-resistant cable 132, a limiting member 133, and a pile foundation 134. The first wind-resistant cable 131 is connected between the first node 115 of the outermost photovoltaic support structure 110 and the limiting member 133. The second wind-resistant cable 132 is connected between the second node 116 of the outermost photovoltaic support structure 110 and the limiting member 133.

[0090] The first wind-resistant cable 131 mainly bears the horizontal tension from the wind. By connecting the outermost photovoltaic support structure 110 and the limiting member 133, the load generated by the wind is transferred to a more stable structure, such as the ground or pile foundation 134. The second wind-resistant cable 132 is similar to the first wind-resistant cable 131 and is also used to bear the horizontal tension generated by the wind. By connecting different nodes, it can provide additional support and stability, further enhancing the wind resistance of the flexible photovoltaic bracket 10.

[0091] The limiting member 133 is a key component in the wind-resistant device 130. It is installed on the pile foundation 134 and is used to fix and connect the first wind-resistant cable 131 and the pile foundation 134, as well as the second wind-resistant cable 132 and the pile foundation 134. It can reduce the risk of slippage or loosening of the first wind-resistant cable 131 and the second wind-resistant cable 132 when under stress, while bearing the tension from the first wind-resistant cable 131 and the second wind-resistant cable 132.

[0092] The pile foundation 134 is the foundation part of the wind-resistant device 130, which is used to provide a stable support point. The fixed limiting member 133 simultaneously bears the tension from the first wind-resistant cable 131 and the second wind-resistant cable 132. The type of pile foundation 134 can be selected according to actual needs and geological conditions, such as reinforced concrete piles or steel pipe piles.

[0093] The wind-resistant device 130 has various structural forms, including but not limited to:

[0094] Example 1: The limiting member 133 is connected to the first node 115 of the photovoltaic support structure 110 via the first wind-resistant cable 131.

[0095] like Figure 3 As shown, in this embodiment, the wind-resistant device 130 can be connected to the first node 115 of the photovoltaic support structure 110. In this case, the wind-resistant device 130 only includes the first wind-resistant cable 131.

[0096] Example 2: The limiting member 133 is connected to the first node 115 of the photovoltaic support structure 110 via the first wind-resistant cable 131, and to the second node 116 of the photovoltaic support structure 110 via the second wind-resistant cable 132.

[0097] like Figure 4 As shown, in this embodiment, the wind-resistant device 130 can be connected to the first node 115 and the second node 116 of the photovoltaic support structure 110 at the same time. In this case, the wind-resistant device 130 includes a first wind-resistant cable 131 and a second wind-resistant cable 132.

[0098] Under wind force, the flexible photovoltaic support 10 will be subjected to horizontal tension. The first wind-resistant cable 131 and the second wind-resistant cable 132 are connected to the outermost support structure and the limiting member 133 to transfer this tension to the pile foundation 134. The limiting member 133 ensures that the cable will not slip or loosen when under force, while the pile foundation 134 provides a stable support point and can withstand the tension from the first wind-resistant cable 131 and the second wind-resistant cable 132.

[0099] It is understandable that by rationally designing the wind-resistant device 130, the overall stability and safety of the flexible photovoltaic support 10 can be improved, the component damage and maintenance costs caused by wind can be reduced, and the service life of the flexible photovoltaic support 10 can be extended.

[0100] This application also provides a photovoltaic system 1, such as... Figure 5 As shown, the photovoltaic system 1 includes a flexible photovoltaic bracket 10 and a photovoltaic module 20, with the photovoltaic module 20 mounted on the photovoltaic support structure 110 of the flexible photovoltaic bracket 10.

[0101] The flexible photovoltaic support 10 is a photovoltaic module 20 support structure based on a tension structure system design. It has advantages such as large span, resistance to wind-induced vibration, adaptability to complex terrain, reduced cost, and shortened construction period. The flexible photovoltaic support 10 is mainly composed of a photovoltaic support structure 110, an inter-module connection structure 120, and a wind-resistant device 130. The photovoltaic support structure 110 is also a prestressed cable structure, which is composed of a series of cables that serve as the installation and load-bearing structure of the module, arranged in a certain pattern, such as the module cable 111, the load-bearing cable 112, and the stabilizing cable 113.

[0102] The wind-resistant device 130 of the flexible photovoltaic support 10 can enhance its stability and safety under severe weather conditions such as strong winds. The wind-resistant device 130 includes components such as a first wind-resistant cable 131, a second wind-resistant cable 132, a limiting member 133, and a pile foundation 134. The components work together to effectively resist the impact of wind on the flexible photovoltaic support 10.

[0103] Photovoltaic module 20 is the core component of photovoltaic power generation system. It mainly utilizes the photovoltaic effect of photovoltaic cells to directly convert solar radiation energy into electrical energy. Photovoltaic module 20 is usually composed of solar cells, battery packs, charge and discharge controllers and inverters. On flexible photovoltaic bracket 10, photovoltaic module 20 is installed on photovoltaic support structure 110 through specific connection and fixing methods.

[0104] It is understandable that the photovoltaic system 1 can convert solar energy into electrical energy through the joint cooperation of the flexible photovoltaic support 10 and the photovoltaic module 20. The flexibility and stability of the flexible photovoltaic support 10 can provide reliable support and protection for the photovoltaic module 20.
