Description

Technical Field

[0001] This application relates to the field of support technology, and in particular to a photovoltaic support with adjustable tilt angle. It also relates to a photovoltaic system. Background Technology

[0002] A photovoltaic system includes photovoltaic support structures and photovoltaic modules. The photovoltaic support structures are the basic components that fix and support the photovoltaic modules.

[0003] Most photovoltaic (PV) mounting systems are fixed and non-adjustable, causing PV modules to be installed at a fixed tilt angle. This limits the amount of irradiance received by the modules, resulting in low power generation. Currently, for PV mounting systems with adjustable tilt devices, some devices only consider adjusting a single module, while others can adjust multiple modules simultaneously, but only on the same side. Achieving bidirectional adjustment requires multiple devices, making adjustment inconvenient. Summary of the Invention

[0004] The purpose of this application is to provide a tilt-adjustable photovoltaic (PV) bracket that can adjust the tilt angle of multiple PV modules using a single adjustment device, offering convenient and efficient adjustment. Another purpose of this application is to provide a PV system including the aforementioned tilt-adjustable PV bracket.

[0005] To achieve the above objectives, this application provides a tilt-adjustable photovoltaic support bracket, including a fixed frame, mounting brackets installed on the fixed frame, and an adjustment device. The mounting brackets are distributed on both sides of the adjustment device, and photovoltaic modules are mounted on the mounting brackets. Each mounting bracket includes a liftable support leg. The adjustment device is connected to the support legs of the mounting brackets on both sides, and the adjustment device is used to simultaneously change the tilt angle of the photovoltaic modules by synchronously controlling the lifting and lowering of the support legs.

[0006] In some embodiments, the mounting frame includes a support rod, and the mounting bracket and the adjusting device are mounted along the support rod; the mounting bracket also includes a movable leg that is movable along the support rod.

[0007] In some embodiments, the adjustment device includes a drive assembly and a transmission assembly. The transmission assemblies are distributed on both sides of the drive assembly. The transmission assemblies on the same side of the drive assembly are connected to the moving leg.

[0008] In some embodiments, the drive assembly includes a rotating member, and a pair of eccentric wheels are symmetrically arranged about the rotation center of the rotating member. The eccentric wheels are connected to a transmission rod, which is used to drive the transmission assembly.

[0009] In some embodiments, the transmission assembly is mirror-symmetrical on both sides of the drive assembly. The transmission assembly includes an adjustable motion seat and a push-pull rod. The adjustable motion seat is movable along the support rod and is driven by the transmission rod. The push-pull rod is mounted on the adjustable motion seat and is also connected to the actuating leg.

[0010] In some embodiments, the outrigger includes a leg fixing seat, a fixed sleeve rod, and a movable sleeve rod. The leg fixing seat is mounted on the support rod, the fixed sleeve rod is mounted on the leg fixing seat, the movable sleeve rod is fitted onto the fixed sleeve rod, and the movable sleeve rod is connected to the push-pull rod.

[0011] In some embodiments, the movable outrigger includes an outrigger seat and a support column. The outrigger seat is mounted on the support rod and can move along the support rod. The support column is mounted on the outrigger seat.

[0012] In some embodiments, a fixed rod is connected between the outrigger moving seat and the adjusting moving seat, so that the outrigger moving seat and the adjusting moving seat can move along the support rod while maintaining a constant distance, and the outrigger fixed seat is fixed on the support rod; the mounting brackets on both sides of the adjusting device are respectively connected to the transmission rod through the adjusting moving seat and to the transmission rod through the outrigger moving seat.

[0013] In some embodiments, multiple sets of the fixed frame and the mounting frame are arranged side by side. The rotating component includes a wheel, a connecting rod, and a rudder. The wheel is provided with the eccentric wheel. Each fixed frame is equipped with the wheel. The wheel on the multiple sets of fixed frames is connected by the connecting rod. The rudder is connected to any of the wheel.

[0014] This application also provides a photovoltaic system, including the above-mentioned tilt-adjustable photovoltaic bracket, and a photovoltaic module, wherein the photovoltaic module is installed on the tilt-adjustable photovoltaic bracket.

[0015] Compared with the above background technology, the tilt-adjustable photovoltaic support provided in this application includes a fixed frame, a mounting frame, and an adjustment device. The mounting frame and the adjustment device are installed on the fixed frame, and mounting frames are distributed on both sides of the adjustment device. Photovoltaic modules are installed on the mounting frames. The mounting frames include liftable moving legs, and the adjustment device is connected to the moving legs of the mounting frames on both sides.

[0016] In use, the raising and lowering of the outriggers is controlled by an adjustment device. This movement changes the tilt angle of the mounting frame and the photovoltaic modules mounted on it.

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0038] To enable those skilled in the art to better understand the present application, the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0039] With the booming development of the photovoltaic industry, installed capacity has repeatedly reached new highs. As the market develops, cost reduction and efficiency improvement have become key focuses for photovoltaic investment companies. The level of power generation has become a crucial indicator of the quality of a photovoltaic power station. Traditional photovoltaic power stations mostly use fixed-tilt installation of photovoltaic modules. This installation method significantly limits the amount of irradiance that photovoltaic modules can receive, resulting in limited output efficiency and a certain impact on power generation. This directly leads to longer payback periods for investors and poor business performance.

[0040] To address the aforementioned technical issues, this application provides a tilt-adjustable photovoltaic support system, aiming to improve the power generation efficiency of photovoltaic power plants through adjustable support system technology, help photovoltaic enterprises increase efficiency and revenue, and promote the further development of the photovoltaic industry.

[0041] Please refer to Figure 1 , Figure 1 This is a schematic diagram of the tilt-adjustable photovoltaic bracket and photovoltaic system provided in the embodiments of this application.

[0042] like Figure 1As shown, the tilt-adjustable photovoltaic support mainly includes a fixed frame 1, a mounting frame 2, and an adjustment device 3. The mounting frame 2 and the adjustment device 3 are installed on the fixed frame 1, and the mounting frames 2 are distributed on both sides of the adjustment device 3. Photovoltaic modules 4 are installed on the mounting frames 2.

[0043] Please refer to Figure 2 and Figure 3 , Figure 2 This is a schematic diagram of multiple tilt-adjustable photovoltaic brackets provided in the embodiments of this application. Figure 3 This is a schematic diagram of a single tilt-adjustable photovoltaic bracket provided in an embodiment of this application.

[0044] like Figure 2 and Figure 3 As shown, the mounting frame 2 includes liftable support legs 21. The adjustment device 3 is connected to the support legs 21 on both sides of the mounting frame 2. The adjustment device 3 is used to simultaneously change the tilt angle of the photovoltaic module 4 by synchronously controlling the lifting and lowering of the support legs 21.

[0045] In this embodiment, preferably, the photovoltaic module 4 is mounted on the upper side of the mounting frame 2, and the mounting frame 2 is mounted on the upper side of the fixed frame 1. With the adjusting device 3 as the central position on the fixed frame 1, there are mounting frames 2 and photovoltaic modules 4 mounted on the mounting frames 2 on both sides of the central position. At this time, the mounting frames 2 and photovoltaic modules 4 on both sides can be adjusted synchronously through the central adjusting device 3. The force transmission path between the adjusting device 3 and the mounting frame 2 for adjustment is simple.

[0046] When using the tilt-adjustable photovoltaic bracket, the lifting and lowering action of the supporting leg 21 is controlled by the adjustment device 3. The lifting and lowering action of the supporting leg 21 changes the tilt angle of the mounting frame 2 and the photovoltaic module 4 installed on the mounting frame 2. The tilt angle of the photovoltaic module 4 is then adjusted by the adjustment device 3. The tilt angle of the mounting frame 2 and the photovoltaic module 4 installed on the mounting frame 2 on both sides of the adjustment device 3 is adjusted synchronously.

[0047] This tilt-adjustable photovoltaic bracket can adjust the tilt angle of multiple photovoltaic modules 4 using a single adjustment device 3, and can also achieve synchronous adjustment of the tilt angle of photovoltaic modules 4 in different directions on both sides of the adjustment device 3, featuring convenient adjustment and high adjustment efficiency.

[0048] Please continue to refer to this. Figure 2 and Figure 3 In some embodiments, the mounting bracket 1 includes a support rod 11, a mounting bracket 2 and an adjustment device 3 mounted along the support rod 11.

[0049] like Figure 2 and Figure 3As shown, the mounting bracket 1 also includes a front column 12 and a rear column 13. The front column 12 and the rear column 13 are respectively located at the front end and the rear end of the support rod 11. The front column 12 and the rear column 13 serve to support the tilt-adjustable photovoltaic bracket and the photovoltaic module 4.

[0050] With the length of the support rod 11 as the longitudinal direction, the mounting frame 2 and the adjustment device 3 are longitudinally distributed on the support rod 11. The adjustment device 3 is located in the middle of the longitudinal direction. There are mounting frames 2 on both the front and rear sides of the longitudinal direction of the adjustment device 3. The tilt angle adjustable photovoltaic bracket can simultaneously adjust the tilt angle of multiple photovoltaic modules 4 on the front and rear sides of the longitudinal direction through the adjustment device 3.

[0051] In one specific implementation, please refer to [link / reference]. Figure 1 and Figure 2 In the horizontal direction perpendicular to the length direction of the support rod 11, multiple sets of fixing frame 1 and mounting frame 2 are arranged side by side. At this time, the photovoltaic modules 4 are arranged in multiple rows in the horizontal direction. The tilt angle adjustable photovoltaic bracket can also adjust the tilt angle of the multiple rows of photovoltaic modules 4 in the horizontal direction synchronously through the adjustment device 3.

[0052] In one specific embodiment, the mounting frame 2 further includes a movable support leg 22, which can move along the support rod 11. The movable support leg 22 works in conjunction with the action support leg 21. When the action support leg 21 moves up or down, the movable support leg 22 moves along the support rod 11 in coordination with the action support leg 21, ensuring the smooth execution of the action support leg 21's movement.

[0053] In one case, a mounting bracket 2 includes an action leg 21 and a movable leg 22, such as... Figure 2 and Figure 3 As shown, the movable support leg 22 is located on the longitudinal front side, and the moving support leg 21 is located on the longitudinal rear side. Photovoltaic modules 4 can be installed on the upper ends of the moving support leg 21 and the movable support leg 22, or a support assembly can be first installed on the upper ends of the moving support leg 21 and the movable support leg 22, and then the photovoltaic modules 4 can be installed on the support assembly. When the moving support leg 21 is raised or lowered to the same height as the movable support leg 22, the photovoltaic modules 4 are in a horizontal state, and the distance between the moving support leg 21 and the movable support leg 22 is at its maximum. When the moving support leg 21 is raised or lowered, causing the photovoltaic modules 4 to no longer be in a horizontal state, the movable support leg 22 moves along the support rod 11 to coordinate with the operation of the moving support leg 21, and the distance between the moving support leg 21 and the movable support leg 22 decreases.

[0054] Please continue to refer to this. Figure 2 and Figure 3In some embodiments, the adjustment device 3 includes a drive component 31 and a transmission component 32. The drive component 31 can be manually controlled or automatically controlled. The drive component 31 outputs power to the transmission component 32, which drives the action leg 21 to achieve the lifting action.

[0055] In this embodiment, transmission components 32 are distributed on both sides of the drive assembly 31. The transmission components 32 on the same side of the drive assembly 31 are connected to the moving legs 21. That is, the moving legs 21 of the mounting bracket 2 on the longitudinal front side are connected to the transmission components 32 on the longitudinal front side of the drive assembly 31, and the moving legs 21 of the mounting bracket 2 on the longitudinal rear side are connected to the transmission components 32 on the longitudinal rear side of the drive assembly 31. At this time, the force transmission paths of the two moving legs 21 in the longitudinal direction are independent. The drive assembly 31 is connected to the transmission components 32. Under the drive of the transmission components 32, the moving legs 21 are raised and lowered by the drive assembly 31.

[0056] Please refer to Figure 4 , Figure 4 This is a schematic diagram of the tilt-adjustable photovoltaic bracket provided in an embodiment of this application.

[0057] like Figure 4 As shown, the drive assembly 31 includes a rotating member 311, and a pair of eccentric wheels 312 are symmetrically arranged about the rotation center of the rotating member 311. The eccentric wheels 312 are connected to a transmission rod 313, which is used to drive the transmission assembly 32.

[0058] In this embodiment, there is a certain eccentric distance between the eccentric wheel 312 on the rotating member 311 and the rotation center of the rotating member 311. Based on the cam principle, when the rotating member 311 rotates, the eccentric wheel 312 drives the transmission rod 313 to swing, the transmission rod 313 applies force to the transmission assembly 32, and finally the transmission assembly 32 drives the action leg 21 to move.

[0059] Furthermore, the transmission assembly 32 is mounted on the support rod 11. The transmission assembly 32 includes an adjusting motion seat 321 and a push-pull rod 322. The adjusting motion seat 321 can move along the support rod 11 and is driven by the transmission rod 313. The push-pull rod 322 is mounted on the adjusting motion seat 321 and is also connected to the actuating leg 21. In use, the transmission rod 313 applies force to the adjusting motion seat 321, causing the adjusting motion seat 321 to move along the support rod 11, and finally, the push-pull rod 322 drives the actuating leg 21 to move.

[0060] It should be noted that because the rotating component 311 is located in the middle and the pair of transmission rods 313 are located on both sides, when the rotating component 311 rotates, the movement directions of the pair of transmission rods 313 are opposite. However, it is necessary to achieve the same tilt angle adjustment for the photovoltaic modules 4 on both sides. Therefore, the transmission components 32 on both sides of the drive component 31 need to be arranged in a mirror symmetrical manner. This way, under the combined action of the opposite forces applied by the transmission rods 313 and the opposite forces applied by the transmission components 32, the tilt angle adjustment direction of the photovoltaic modules 4 on both sides can be the same. The arrangement of the two transmission components 32 can be referred to Figure 3 As shown.

[0061] Please continue to refer to this. Figure 4 And refer to Figure 5 , Figure 5 This is a schematic diagram of the action leg provided in an embodiment of this application.

[0062] like Figure 4 and Figure 5 As shown, the outrigger 21 includes a leg fixing seat 211, a fixed sleeve rod 212, and a movable sleeve rod 213. The leg fixing seat 211 is installed on the support rod 11, the fixed sleeve rod 212 is installed on the leg fixing seat 211, the movable sleeve rod 213 is fitted onto the fixed sleeve rod 212, and the movable sleeve rod 213 is connected to the push-pull rod 322.

[0063] In this embodiment, the fixed sleeve 212 and the movable sleeve 213 achieve the lifting function through an inner and outer sleeve assembly. The fixed sleeve 212 can be a lower sleeve, and the movable sleeve 213 can be an upper sleeve. The inner diameter of the upper sleeve is larger than the outer diameter of the lower sleeve, thereby enabling the supporting leg 21 to lift when the movable sleeve 213 moves along the fixed sleeve 212. In use, the push-pull rod 322 applies force to the movable sleeve 213, causing the movable sleeve 213 to move relative to the fixed sleeve 212 under the drive of the push-pull rod 322.

[0064] In some cases, the outrigger fixing seat 211 is fixed on the support rod 11, so that the fixed sleeve rod 212 can neither move nor rotate, while the movable sleeve rod 213 can move along the fixed sleeve rod 212. Therefore, the moving outrigger 21 cannot move along the support rod 11, but can rise and fall relative to the support rod 11.

[0065] Please continue to refer to this. Figure 4 In some embodiments, the movable outrigger 22 includes an outrigger seat 221 and a support column 222. The outrigger seat 221 is mounted on the support rod 11 and can move along the support rod 11. The support column 222 is mounted on the outrigger seat 221.

[0066] In some cases, the outrigger seat 221 can move on the support rod 11, allowing the support column 222 to move on the support rod 11. Comparing the outrigger seat 221 and the outrigger fixed seat 211, it can be found that the moving outrigger 21 is fixed on the support rod 11, and its longitudinal position is fixed, while the movable outrigger 22 can move on the support rod 11, and its longitudinal position is not fixed.

[0067] Please continue to refer to this. Figure 4 In some embodiments, a fixing rod 223 is connected between the outrigger motion seat 221 and the adjusting motion seat 321, and the outrigger fixing seat 211 is fixed on the support rod 11.

[0068] In this embodiment, the outrigger seat 221 and the adjusting seat 321 move along the support rod 11 while maintaining a constant distance. At this time, the support column 222 is rotatably connected to the outrigger seat 221, allowing the support column 222 to move and rotate on the support rod 11. During use, the transmission rod 313 applies force to the adjusting seat 321, causing it to move along the support rod 11. The push-pull rod 322 applies force to the movable sleeve rod 213, causing the movable sleeve rod 213 to move relative to the fixed sleeve rod 212 under the drive of the push-pull rod 322, thereby achieving the raising and lowering of the outrigger 21. Simultaneously, the outrigger seat 221, driven by the fixed rod 223, moves along the support rod 11 together with the adjusting seat 321. The movable outrigger 22 moves and rotates on the support rod 11, coordinating with the raising and lowering of the outrigger 21.

[0069] Please continue to refer to this. Figure 4 For the mounting brackets 2 on both longitudinal sides of the adjusting device 3, the connection method between the transmission rod 313 and the transmission assembly 32 used to drive the transmission assembly 32 is different. For example Figure 4 As shown, for the mounting bracket 2 on the longitudinal front side of the adjustment device 3, the transmission rod 313 on the front side is connected to the adjustment motion seat 321; for the mounting bracket 2 on the longitudinal rear side of the adjustment device 3, the transmission rod 313 on the rear side is connected to the support leg motion seat 221.

[0070] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the adjustment device provided in an embodiment of this application.

[0071] In some embodiments, the rotating component 311 includes a wheel 3111, a connecting rod 3112, and a rudder 3113. An eccentric wheel 312 is provided on the wheel 3111. Multiple sets of fixed frames 1 and mounting frames 2 are arranged side by side. Each fixed frame 1 is equipped with a wheel 3111. The wheel 3111s on the multiple sets of fixed frames 1 are connected by the connecting rod 3112. The rudder 3113 is connected to any wheel 3111.

[0072] In one specific implementation, please refer to [link / reference]. Figures 1 to 6 The tilt-adjustable photovoltaic bracket is used to install photovoltaic modules 4 and adjust the tilt angle of photovoltaic modules 4. The tilt-adjustable photovoltaic bracket includes a fixed frame 1, a mounting frame 2, and an adjustment device 3.

[0073] The fixing frame 1 includes support rods 11, front column 12 and rear column 13. The fixing frame 1 has multiple sets arranged in the horizontal direction, and the support rods 11 are arranged in multiple rows.

[0074] Mounting frame 2 includes movable support legs 21, crossbeams 23, and inclined beams 24. Mounting frames 2 are arranged on each row of support rods 11. For a single row, the inclined beams 24 are arranged longitudinally, with triangular connectors at the lower sides of both ends. The front end of the inclined beam 24 is rotatably connected to the upper end of the movable support leg 22 via the triangular connectors, and the rear end of the inclined beam 24 is rotatably connected to the upper end of the movable support leg 21 via the triangular connectors. The crossbeams 23 are arranged transversely and fixed to the upper side of the inclined beams 24, serving to fix the photovoltaic modules 4.

[0075] The outrigger 21 includes a leg fixing seat 211, a fixed sleeve rod 212, and a movable sleeve rod 213. The leg fixing seat 211 is fixedly connected to the support rod 11. A triangular connector is provided on the upper side of the leg fixing seat 211. However, the upper side of the leg fixing seat 211 is fixedly connected to the fixed sleeve rod 212 through the triangular connector. The lower end of the movable sleeve rod 213 is sleeved on the fixed sleeve rod 212, and the upper end of the movable sleeve rod 213 is rotatably connected to the rear end of the inclined beam 24.

[0076] The movable outrigger 22 includes an outrigger seat 221 and a support column 222. The outrigger seat 221 is slidably connected to the support rod 11. A triangular connector is provided on the upper side of the outrigger seat 221. The upper side of the outrigger seat 221 is rotatably connected to the support column 222 through the triangular connector. The upper end of the support column 222 is rotatably connected to the front end of the inclined beam 24.

[0077] The adjustment device 3 includes a drive assembly 31 and a transmission assembly 32. The drive assembly 31 includes a rotating component 311, an eccentric wheel 312, and a transmission rod 313. The rotating component 311 includes a wheel 3111, a connecting rod 3112, and a rudder 3113. Each row of support rods 11 is provided with a wheel 3111. Multiple rows of wheel 3111 are coaxially connected by connecting rods 3112. The wheel 3111 in the first row is coaxially connected with the rudder 3113. For a single row, a pair of eccentric wheels 312 are symmetrically arranged on the wheel 3111. The eccentric wheel 312 on the longitudinal front side is rotatably connected to the rear end of the transmission rod 313 on the longitudinal front side, and the eccentric wheel 312 on the longitudinal rear side is rotatably connected to the front end of the transmission rod 313 on the longitudinal rear side. The transmission assembly 32 includes an adjusting motion seat 321 and a push-pull rod 322, and each row of support rods 11 is equipped with a transmission assembly 32. For a single row, the front end of the longitudinally front transmission rod 313 is rotatably connected to the longitudinally front adjusting motion seat 321, the longitudinally front adjusting motion seat 321 is rotatably connected to the lower end of the longitudinally front push-pull rod 322, the upper end of the longitudinally front push-pull rod 322 is rotatably connected to the longitudinally front movable sleeve rod 213, and the longitudinally front adjusting motion seat 321 is rotatably connected to the longitudinally front movable sleeve rod 213. The forward-facing support leg seat 221 is fixedly connected to the longitudinal rear support leg seat 221 via a fixing rod 223. The rear end of the longitudinal rear transmission rod 313 is rotatably connected to the longitudinal rear support leg seat 221. The longitudinal rear support leg seat 221 is fixedly connected to the longitudinal rear adjustment seat 321 via a fixing rod 223. The longitudinal rear adjustment seat 321 is rotatably connected to the lower end of the longitudinal rear push-pull rod 322. The upper end of the longitudinal rear push-pull rod 322 is rotatably connected to the longitudinal rear movable sleeve rod 213.

[0078] In operation, the steering wheel 3113 rotates, causing the wheel 3111 and eccentric wheel 312 to rotate. The eccentric wheel 312 causes the transmission rod 313 to be stressed, which in turn causes the fixed rod 223, the outrigger seat 221, and the adjusting seat 321 to move. Simultaneously, the triangular connectors fixed to the outrigger seat 221 and the adjusting seat 321 are stressed, causing the support column 222 and the push-pull rod 322 to move back and forth. The angle of the support column 222 changes as it moves, causing the tilt angle of the inclined beam 24 and the photovoltaic module 4 fixed to its upper end to change. At the same time, the push-pull rod 322 is also stressed, and its angle changes, causing the movable sleeve 213 to move up and down along the fixed sleeve 212. The height of the movable sleeve 213 changes, causing the tilt angle of the inclined beam 24 and the photovoltaic module 4 to change.

[0079] This tilt-adjustable photovoltaic bracket can adapt to various installation scenarios. By rotating the rudder disk 3113, the wheel disk 3111 and connecting rod 3112 rotate, pushing or pulling the movable support leg 22 to move back and forth. At the same time, pulling or pushing the push-pull rod 322 to move back and forth, so that the movable sleeve rod 213 is subjected to force and moves up or down along the fixed sleeve rod 212, thereby simultaneously adjusting the height of the front and rear mounting brackets 2, achieving a more efficient adjustment of the tilt angle of the photovoltaic module 4. By adjusting the tilt angle of the photovoltaic module 4, the power generation of the photovoltaic power station can be improved.

[0080] This application also provides a photovoltaic system, including the aforementioned tilt-adjustable photovoltaic bracket, and a photovoltaic module 4, which is mounted on the tilt-adjustable photovoltaic bracket. This photovoltaic system should possess all the beneficial effects of the aforementioned tilt-adjustable photovoltaic bracket, which will not be elaborated upon here.

[0081] In this embodiment, the photovoltaic modules 4 are arranged in multiple groups longitudinally, as shown in the two groups in the figure; the photovoltaic modules 4 are also arranged in multiple rows laterally, and the tilt angles of the multiple rows and multiple groups of photovoltaic modules 4 are synchronously adjusted by the same set of adjustment devices 3. Taking two groups of photovoltaic modules 4 in each row as an example, the adjustment device 3 is located in the middle of the two groups of photovoltaic modules 4, and rotating the rudder disk 3113 can synchronously adjust the tilt angles of the photovoltaic modules 4 in the front and rear positions, as well as the tilt angles of the multiple rows of photovoltaic modules 4 in the lateral direction.
