It can balance the use effects of the wind resistance device in windy and windless environments, improve the wind resistance ability of the flexible photovoltaic support, and can prevent the guy wire from sagging in a windless or light wind environment and interfering with other components or being disturbed by other external environments. At the same time, it can reduce the elongation of the guy wire in a windy environment, thereby reducing the forces on the guy wire and the pile foundation, and can effectively reduce the size and strength requirements of the pile foundation and the guy wire.

[0009] According to an embodiment of this application, the pile foundation has a cavity extending vertically and a through hole provided on the top wall of the cavity.

[0056] The embodiments of the present application will be described in detail below. Examples of the embodiments are shown in the drawings, where 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 drawings are exemplary and are only used to explain the present application and should not be construed as a limitation of the present application.

[0057] The present application aims to at least solve the technical problem that it is difficult to control the overall upward displacement during wind resistance of a flexible photovoltaic support in the related art. For this purpose, the present application proposes a wind resistance device, a flexible photovoltaic support, and a photovoltaic system to balance the use effects in windy and windless environments.

[0058] Below, refer to Figures 1-10 Describe the wind resistance device according to the embodiments of the present application.

[0059] As Figure 1 shown, the wind resistance device 1 is applied to a flexible photovoltaic support and includes: a pile foundation 10, a counterweight member 20, and a guy wire 30.

[0060] The pile foundation 10 has a limiting structure;

[0061] The counterweight member 20 is vertically movably installed on the pile foundation 10 and is limited by the limiting structure when moving to the topmost position;

[0062] One end of the guy wire 30 is connected to the counterweight member 20.

[0063] In the technical solution of this application, the pile foundation 10 serves as the foundation of the entire wind-resistant device 1, responsible for bearing the weight of the flexible photovoltaic support and the photovoltaic modules thereon, as well as the wind load. It can be a concrete component, a metal component, or a hybrid of concrete and metal. At the same time, it has a limiting structure, which is usually located at the top or a specific position of the pile foundation 10 and is used to limit the movement range of the counterweight 20 to ensure that it does not break away from the pile foundation 10 under specific environmental conditions. The counterweight 20 is a key component to increase the stability of the flexible photovoltaic support. It is vertically movably installed on the pile foundation 10 and provides an additional downward pressure through its own weight, thereby enhancing the wind resistance of the flexible photovoltaic support.

[0064] The counterweight 20 can move up and down inside the pile foundation 10 along a specific track or guiding device. When the counterweight 20 moves to the topmost position, it will be limited by the limiting structure of the pile foundation 10 to prevent it from rising further and breaking away from the pile foundation 10. The material, shape, and weight of the counterweight 20 are accurately calculated and designed according to factors such as the specifications of the flexible photovoltaic support and the wind conditions at the installation site. The counterweight 20 can be a concrete component or a steel component, and different materials have different connection methods.

[0065] The guy wire 30 is mainly used to provide additional support in the crosswind direction and enhance the overall stability of the flexible photovoltaic support. One end of the guy wire 30 is connected to the counterweight 20, and the other end is fixed to the flexible photovoltaic support. When the wind acts on the flexible photovoltaic support, the guy wire 30 can bear part of the wind load and reduce the burden on the pile foundation 10 and the counterweight 20. The guy wire 30 is usually made of high-strength and corrosion-resistant materials, such as steel wire ropes or nylon ropes, to ensure its stable performance in various harsh environments.

[0066] In a windless or light-wind environment, the counterweight 20 provides a stable downward pressure for the flexible photovoltaic support through its own weight, making the guy wire 30 straight but not taut, avoiding interference with other components or being disturbed by other external environments due to the slack of the guy wire 30. When the wind is strong enough, in a windy environment, the flexible photovoltaic support moves upward under the influence of the wind, and the guy wire 30 begins to play a role and bears part of the wind load. The counterweight 20 connected to the guy wire 30 moves upward in the cavity 111 of the pile foundation 10. When the counterweight 20 moves to the topmost position of the pile foundation 10, it will be limited by the limiting structure of the pile foundation 10 to prevent it from rising further, thereby ensuring the safety and stability of the entire wind-resistant device 1 and restricting the displacement of the flexible photovoltaic support.

[0067] According to the wind-resistant device 1 provided in the embodiment of the present application, through the cooperation of the pile foundation 10, the counterweight 20 and the cable wind rope 30, the connection structure is simple and the installation is convenient. The use effect of the wind-resistant device 1 in windy and windless environments can be balanced, and the wind-resistant ability of the flexible photovoltaic bracket can be improved. The cable wind rope 30 can be prevented from loosening in a windless or low-wind environment, causing interference with other components or being disturbed by other external environments. At the same time, the elongation of the cable wind rope 30 in a windy environment can be reduced, thereby reducing the force on the cable wind rope 30 and the pile foundation 10, and the size and strength requirements of the pile foundation 10 and the cable wind rope 30 can be effectively reduced.

[0068] In some embodiments, Figures 2-5 As shown, the pile foundation 10 has a cavity 111 extending vertically and a through hole 121 arranged on the top wall of the cavity 111, the counterweight 20 is suitable for moving vertically in the cavity 111, at least one of the counterweight 20 and the cable rope 30 passes through the through hole 121, and the maximum cross-sectional area of ​​the portion of the counterweight 20 located at the lower end of the through hole 121 is larger than the cross-sectional area of ​​the through hole 121, so as to be limited by the through hole 121.

[0069] In the technical solution of the present application, the pile foundation 10 has a cavity 111 extending vertically, providing space for the counterweight 20 to move. A through hole 121 is provided on the top wall of the cavity 111, which is used to pass through at least one of the counterweight 20 and the cable wind rope 30. The cable wind rope 30 can pass through the through hole 121 on the top wall of the cavity 111. The counterweight 20 is limited when passing through the through hole 121. The counterweight 20 moves vertically within a certain range in the cavity 111 of the pile foundation 10. The maximum cross-sectional area of ​​the portion of the counterweight 20 located at the lower end of the through hole 121 is greater than the cross-sectional area of ​​the through hole 121, which can ensure that the counterweight 20 is limited when passing through the through hole 121 to prevent it from completely detaching from the cavity 111 or moving excessively.

[0070] It can be understood that by passing the counterweight 20 or the wind rope 30 through the through hole 121 and connecting and limiting the pile foundation 10 with the cavity 111 through the through hole 121, the stability of the pile foundation 10 can be increased to prevent it from excessive displacement under the action of wind or other external forces. By limiting the counterweight 20 at the lower end of the through hole 121 by utilizing the characteristic that the cross-sectional area of ​​the through hole 121 is larger than the cross-sectional area of ​​the through hole 121, the stability and safety of the structure can be ensured.

[0071] In some embodiments, Figures 2-5 As shown, the inner diameter of the cavity 111 is greater than the maximum inner diameter of the counterweight 20 .

[0072] In the technical solution of this application, the cavity 111 of the pile foundation 10 extends vertically, providing space for the counterweight 20 to move. The inner diameter of the cavity 111 is determined by the size of the counterweight 20 to ensure that the counterweight 20 can move smoothly vertically within the cavity 111. The maximum inner diameter of the counterweight 20, that is, the maximum cross-sectional dimension of the counterweight 20 in the vertical direction, is smaller than the inner diameter of the cavity 111 to ensure that the counterweight 20 can fully enter and move within the cavity 111.

[0073] It can be understood that the inner diameter of the cavity 111 being larger than the maximum inner diameter of the counterweight 20 can ensure that the counterweight 20 has sufficient space to move within the cavity 111, and at the same time can prevent the counterweight 20 from rubbing or colliding with the wall of the cavity 111 during movement, thereby maintaining the stability and reliability of the system.

[0074] In some embodiments, as Figures 1-5 shown, the pile foundation 10 includes: a pile foundation body 110 and a first stop member 120.

[0075] The pile foundation body 110 has a cavity 111, and the upper end of the cavity 111 is open;

[0076] The first stop member 120 is installed at the top of the pile foundation body 110 and has a through hole 121.

[0077] In the technical solution of this application, the pile foundation body 110 is the main structure of the pile foundation 10, extending deep into the ground, used to support and transfer the weight of the building to the ground. The pile foundation body 110 has a cavity 111 inside, extending along the length direction of the pile foundation body 110, used to accommodate the counterweight 20. The upper end of the cavity 111 is open, that is, the top of the cavity 111 is not closed, allowing other components or objects to enter the inside of the cavity 111 from the top. The first stop member 120 is installed at the top of the pile foundation body 110, and its main function is to provide support and fixation to ensure the stability and safety of the pile foundation body 110. The first stop member 120 has a through hole 121, allowing certain components or objects, such as the counterweight 20 or the guy wire 30, to pass through the inside of the cavity 111 of the pile foundation body 110 and extend to the outside of the pile foundation body 110. Adding the counterweight 20 in the cavity 111 can provide additional weight and friction, thereby enhancing the connection between the pile foundation 10 and the foundation.

[0078] It can be understood that the pile foundation 10 combines the pile foundation body 110 and the first stop member 120, and realizes the functions of stable support and flexible adjustment through the structures of the cavity 111 and the through hole 121.

[0079] In some embodiments, as Figures 1-5 shown, the counterweight 20 includes: a counterweight block 210 and a hook 220.

[0080] The counterweight 210 is located within the cavity 111, and the maximum cross-sectional area of the counterweight 210 is greater than the cross-sectional area of the through-hole 121;

[0081] The hook 220 is connected to one end of the guy wire 30 and is also connected to the counterweight 210. The hook 220 is adapted to pass through the through-hole 121.

[0082] In the technical solution of the present application, the counterweight 210 is located within the cavity 111 of the pile foundation 10, and its main function is to provide weight to increase the stability of the flexible photovoltaic support. The maximum cross-sectional area of the counterweight 210 is greater than the cross-sectional area of the through-hole 121, and the through-hole 121 serves to limit the position of the counterweight 210. When the counterweight 210 moves within the cavity 111 and approaches the through-hole 121, due to the difference in cross-sectional area, the counterweight 210 cannot continue to rise and break away from the cavity 111. The hook 220 is an important component of the counterweight member 20. It can pass through the through-hole 121, with one end connected to the guy wire 30 and the other end connected to the counterweight 210. It also connects the counterweight member 20 to the outside of the pile foundation 10 through the through-hole 121.

[0083] By adjusting the weight and position of the counterweight 210, as well as the tension of the guy wire 30, flexible adjustment of the structural stability can be achieved. The guy wire 30 is connected to the counterweight 210 through the hook 220. When the wind acts on the entire structure, the guy wire 30 can apply a pulling force to the counterweight 210 through the hook 220, effectively dispersing the wind load to the pile foundation 10, thereby reducing the impact and damage to the main structure and enhancing the structural stability. At the same time, since the hook 220 passes through the through-hole 121, the pulling force can be more effectively transmitted to the pile foundation 10, further improving the wind resistance of the structure.

[0084] It can be understood that the counterweight member 20 is composed of the counterweight 210 and the hook 220. The counterweight 210 is located within the cavity 111 of the pile foundation 10 and is connected to the guy wire 30 through the hook 220. The maximum cross-sectional area of the counterweight 210 is greater than the cross-sectional area of the through-hole 121 to ensure that the counterweight 210 does not break away when moving within the cavity 111. The hook 220 can pass through the through-hole 121 to connect the counterweight member 20 to the outside of the pile foundation 10, thereby enhancing the structural stability.

[0085] In some embodiments, as Figures 5-10 shown, the counterweight member 20 includes: a connecting rod 230 and an anti-disengagement member 240.

[0086] The connecting rod 230 is connected to one end of the guy wire 30 and passes through the through-hole 121;

[0087] The anti-disengagement member 240 is connected to the connecting rod 230 and is located within the cavity 111. The maximum cross-sectional area of the anti-disengagement member 240 is greater than the area of the through-hole 121.

[0088] In the technical solution of the present application, the counterweight 20 is composed of a connecting rod 230 and a anti-disengagement member 240. The connecting rod 230 is connected to the guy wire 30 and passes through the through-hole 121, connecting the counterweight 20 to the outside of the pile foundation 10. The anti-disengagement member 240 is connected to the connecting rod 230 and is located inside the cavity 111. Its maximum cross-sectional area is larger than the area of the through-hole 121 to prevent the counterweight 20 from accidentally falling off.

[0089] The connecting rod 230 is one of the main parts of the counterweight 20 and is connected to one end of the guy wire 30. The connecting rod 230 can pass through the through-hole 121, thereby connecting the counterweight 20 to the outside of the pile foundation. The guy wire 30 can transmit the tensile force to the pile foundation 10 through the connecting rod 230, thereby enhancing the stability of the structure. The connecting rod 230 can be composed of threaded steel, washers and nuts, or can be composed of small steel pipes, bottom plates and steel rings, etc. The anti-disengagement member 240 is a component connected to the connecting rod 230 and is located inside the cavity 111. Its main function is to prevent the counterweight 20 from accidentally falling off from inside the cavity 111. The maximum cross-sectional area of the anti-disengagement member 240 is larger than the area of the through-hole 121. When the anti-disengagement member 240 moves to a position close to the through-hole 121, it will be limited by the through-hole 121 and cannot continue to rise, thereby ensuring that the counterweight 20 remains inside the cavity 111.

[0090] It can be understood that through the connection of the guy wire 30 and the connecting rod 230, the wind load can be effectively transmitted to the pile foundation 10, thereby enhancing the wind resistance of the structure. The anti-disengagement member 240 can ensure the stability of the counterweight 20 inside the cavity 111 and prevent the counterweight 20 from accidentally falling off due to wind force or other factors.

[0091] In some embodiments, such as Figure 8 and Figure 10 shown, when the pile foundation 10 includes a pile foundation body 110 and a first stop member 120, the pile foundation 10 further includes a second stop member 130. The second stop member 130 is installed above the first stop member 120 and has an avoidance hole 131. The rod body of the connecting rod 230 passes through the avoidance hole 131, and the maximum cross-sectional area of the connecting ring of the connecting rod 230 is smaller than the cross-sectional area of the avoidance hole 131. The connecting ring is connected to one end of the guy wire 30.

[0092] In the technical solution of the present application, the pile foundation body 110 is the main load-bearing part of the pile foundation 10, responsible for transmitting the weight of the building to the underlying soil or rock formation. The first stop member 120 is installed on the pile foundation body 110, and its purpose is to fix or guide other components related to the pile foundation 10, such as the guy wire 30 or the connecting rod 230. The second stop member 130 is installed above the first stop member 120 and includes an avoidance hole 131, allowing other components to pass through. The rod body of the connecting rod 230 passes through the avoidance hole 131.

[0093] The connecting rod 230 is composed of a rod body and a connecting ring. The rod body is the main part of the connecting rod 230, responsible for transmitting force or fixing other components. The connecting ring is a connection point for connecting one end of the guy wire 30. The maximum cross-sectional area of the connecting ring is smaller than the cross-sectional area of the avoidance hole 131, that is, the connecting ring can easily pass through the avoidance hole 131 without interfering with the second stop member 130.

[0094] The guy wire 30 is a rope used to fix or stabilize a structure. One end of the guy wire 30 is connected to the connecting ring, and the other end is connected to the photovoltaic support. A plurality of guy wire clamps 310 are provided at both ends of the guy wire 30 to prevent the guy wire 30 from slipping, wearing excessively, or breaking during use. When the guy wire 30 is tensioned, the force can be transmitted to the pile foundation body 110 through the connecting rod 230, the first stop member 120, and the second stop member 130, thereby increasing the stability of the pile foundation 10.

[0095] It can be understood that by using components such as the first stop member 120, the second stop member 130, the connecting rod 230, and the guy wire 30, the stability and reinforcement of the pile foundation 10 can be achieved.

[0096] Next, the embodiments of the present application will be specifically described from two different implementation perspectives.

[0097] I. The counterweight 20 is composed of a counterweight block 210 and a hook 220

[0098] As Figures 1-5 shown, the wind resistance device 1 is applied to a flexible photovoltaic support, including: a pile foundation 10, a counterweight 20, and a guy wire 30. Among them, the pile foundation 10 includes: a pile foundation body 110 and a first stop member 120. The pile foundation body 110 has a cavity 111 that extends along the length direction of the pile foundation body 110 for accommodating the counterweight 20, and the upper end of the cavity 111 is open. The first stop member 120 is installed at the top of the pile foundation body 110 and has a through hole 121. The guy wire 30 passes in and out of the inside of the cavity 111 through the through hole 121. The counterweight 20 is vertically movably installed on the pile foundation 10 and is limited by the first stop member 120 when moving to the topmost position to prevent it from rising further and detaching from the pile foundation 10. One end of the guy wire 30 is connected to the hook 220 of the counterweight 20, and the other end is connected to the flexible photovoltaic support.

[0099] The counterweight block 210 is located inside the cavity 111, and the inner diameter of the cavity 111 is larger than the maximum inner diameter of the counterweight 20. The maximum cross-sectional area of the counterweight block 210 is larger than the cross-sectional area of the through hole 121. The hook 220 is connected to one end of the guy wire 30 and is also connected to the counterweight block 210. The hook 220 is adapted to pass through the through hole 121.

[0100] In the normal state, the counterweight 20 provides a stable downward pressure for the flexible photovoltaic support through its own weight, and straightens but does not tighten the guy wire 30, avoiding the relaxation of the guy wire 30 under the action of construction stage and wind pressure, resulting in an unappealing appearance. When the wind force increases, the whole flexible photovoltaic support moves upward, and the guy wire 30 starts to play a role, bearing part of the wind load and restricting the displacement of the flexible photovoltaic support through its connection with the counterweight 20. The first stop 120 of the pile foundation 10 ensures that the counterweight 20 does not break away from the pile foundation, thus ensuring the safety and stability of the entire wind resistance device 1.

[0101] II. The counterweight 20 is composed of a connecting rod 230 and an anti-disengagement member 240

[0102] As Figures 6-10 shown, the wind resistance device 1 is applied to a flexible photovoltaic support, including: a pile foundation 10, a counterweight 20, and a guy wire 30. The pile foundation 10 includes: a pile foundation body 110, a first stop 120, and a second stop 130. The pile foundation body 110 has a cavity 111 that extends along the length direction of the pile foundation body 110 for accommodating the counterweight 20, and the upper end of the cavity 111 is open. The first stop 120 is installed at the top of the pile foundation body 110 and has a through hole 121. The second stop 130 is installed above the first stop 120 and has an avoidance hole 131. The rod body of the connecting rod 230 passes through the avoidance hole 131, and the maximum cross-sectional area of the connecting ring of the connecting rod 230 is smaller than the cross-sectional area of the avoidance hole 131. The connecting ring is connected to one end of the guy wire 30.

[0103] The counterweight 20 is movably installed vertically in the cavity 111 of the pile foundation 10. When it moves to the topmost position, the anti-disengagement member 240 is limited by the first stop 120 to prevent the counterweight 20 from rising further and breaking away from the pile foundation 10. When it moves to the lowermost position, it is limited by the second stop 130 to prevent the counterweight 20 from sliding into the cavity 111 due to the breakage of the guy wire 30. One end of the guy wire 30 is connected to the connecting rod 230 of the counterweight 20, and the other end is connected to the flexible photovoltaic support.

[0104] The connecting rod 230 is connected to one end of the guy wire 30 and passes through the through hole 121. The anti-disengagement member 240 is connected to the connecting rod 230 and is located in the cavity 111. The maximum cross-sectional area of the anti-disengagement member 240 is larger than the area of the through hole 121.

[0105] In the normal state, the counterweight 20 provides a stable downward pressure for the flexible photovoltaic support through its own weight, and straightens but does not tighten the guy wire 30, avoiding the relaxation of the guy wire 30 under the action of construction stage and wind pressure, which may lead to an unattractive appearance. When the wind force increases, the overall flexible photovoltaic support moves upward, and the guy wire 30 starts to play a role, bearing part of the wind load and restricting the displacement of the flexible photovoltaic support through its connection with the counterweight 20. The first stop 120 of the pile foundation 10 ensures that the counterweight 20 does not break away from the pile foundation 10, thus ensuring the safety and stability of the entire wind resistance device 1.

[0106] An embodiment of the present application further provides a flexible photovoltaic support, including: a support frame group, multiple photovoltaic installation cables, a wind protection structure, and a wind resistance device 1.

[0107] The photovoltaic installation cables are connected between the support frame groups and are used for installing photovoltaic modules.

[0108] The wind protection structure is installed on multiple photovoltaic installation cables.

[0109] For the wind resistance device 1, the other end of the guy wire 30 is connected to the wind protection structure.

[0110] In the technical solution of the present application, the support frame group is the basic structure of the flexible photovoltaic support, providing a plane for the installation of photovoltaic modules. The support frame group is usually formed by connecting multiple support columns and crossbeams to form a stable framework. Multiple photovoltaic installation cables are connected between the support frame groups and are used for installing photovoltaic modules. They can be made of steel wires, steel cables or other materials with sufficient strength and flexibility. The photovoltaic modules are installed on the photovoltaic installation cables through clamps or other connecting pieces, forming a flexible installation surface that can change with the shape of the support frame group.

[0111] The wind protection structure is installed on multiple photovoltaic installation cables. The main purpose is to connect multiple photovoltaic installation cables together to enhance the stability of the photovoltaic modules under the action of wind force. The wind protection structure can be a truss structure, or include baffles, grids or other devices that can reduce the direct impact of wind force on the photovoltaic modules. It is designed in various shapes and sizes to adapt to different wind conditions and photovoltaic module layouts. It can also connect multiple rows of photovoltaic systems into a whole and connect the end to one end of the guy wire 30.

[0112] The wind resistance device 1 is a key component in this flexible photovoltaic support. It is connected to the wind protection structure of the flexible photovoltaic support through the guy wire 30. One end of the guy wire 30 is connected to the wind protection structure, and the other end is fixed on the counterweight 20 of the pile foundation 10. When the wind force acts on the flexible photovoltaic support, the wind resistance device 1 can offset the influence of the wind force on the flexible photovoltaic support through the tension of the guy wire 30, thus maintaining the stability and safety of the flexible photovoltaic support.

[0113] It can be understood that through the coordinated action of components such as the support frame group, photovoltaic installation cables, windproof structure, and wind resistance device 1, the flexible photovoltaic support ensures the stability and safety of the photovoltaic modules under the action of wind.

[0114] In some embodiments, the wind resistance device 1 has a first working state and a second working state.

[0115] In the technical solution of this application, in the first working state, the wind resistance device 1 is in a pre-tightened or ready state to cope with the upcoming wind. The guy wire 30 of the wind resistance device 1 is pre-tightened to ensure that it can quickly respond and exert the necessary reaction force when affected by wind. In the second working state, the wind resistance device 1 will actively respond to the wind to ensure the stability and safety of the photovoltaic support.

[0116] When the wind force exceeds the preset threshold, the wind resistance device 1 will quickly respond and apply the necessary tensile force or supporting force to the photovoltaic support through the guy wire 30 to offset the influence of the wind force on the photovoltaic modules. The wind resistance device 1 has a dynamic adjustment function and can adjust the tension or length of the guy wire 30 in real time according to the magnitude and direction of the wind force to maintain the stability of the photovoltaic support. The switching of the wind resistance device 1 between the first working state and the second working state may be automatically completed by the control system or manually controlled by the operator.

[0117] It can be understood that the wind resistance device 1 with the first working state and the second working state provides a more flexible and reliable wind resistance solution for the flexible photovoltaic support. By adjusting the tension or length of the guy wire 30 in different working states, the wind resistance device 1 can effectively cope with various wind conditions and ensure the stability and safety of the flexible photovoltaic support.

[0118] The embodiment of this application also provides a photovoltaic system, including: a flexible photovoltaic support and photovoltaic modules.

[0119] The photovoltaic modules are installed on multiple photovoltaic installation cables.

[0120] In the technical solution of this application, the flexible photovoltaic support, as the basic structure of the system, consists of a support frame group, multiple photovoltaic installation cables, a windproof structure, and a wind resistance device 1, etc., providing stable support for the installation of photovoltaic modules. The support frame group constitutes the framework of the flexible photovoltaic support, and its shape can be designed and adjusted according to needs to adapt to different terrains. Multiple photovoltaic installation cables are connected between the support frame groups to form multiple parallel cableways for installing photovoltaic modules. The windproof structure is installed on the photovoltaic installation cables to enhance the stability of the photovoltaic modules under the action of wind. The wind resistance device 1 is connected to the windproof structure through the guy wire 30, providing additional support and stability when the wind force is large. The wind resistance device 1 has a first working state and a second working state, and can automatically adjust the working state according to the magnitude of the wind force, reducing the risk of damage to the photovoltaic modules and the decline in power generation efficiency caused by excessive wind force.

[0121] The photovoltaic module is the core part of the photovoltaic system, responsible for converting solar energy into electrical energy. It is installed on multiple photovoltaic installation cables through clamps or other connectors to form a continuous photovoltaic array. The spacing and angle of the modules can be adjusted according to needs to achieve the best light reception effect and power generation efficiency, improving the utilization rate of solar energy.

[0122] It can be understood that the photovoltaic system combining the flexible photovoltaic support and the photovoltaic module has the characteristics of flexibility, stability, high efficiency, and environmental protection, and can operate stably under various terrains and climate conditions, providing strong support for sustainable development and the utilization of clean energy.
