[0002] Solar panels (also known as photovoltaic panels or solar panels) are key devices that use the photovoltaic effect to convert solar energy into electrical energy. They are clean, renewable and sustainable. They play an important role in household electricity, commercial electricity, photovoltaic power stations, off-grid applications and other fields. They are one of the important technologies to promote energy transformation and sustainable development.

Solar power generation projects are mostly built in vast areas such as deserts, Gobi, wastelands and oceans, but these areas are mostly strong wind environments, which can easily peel off the solar panels from the bracket units, causing damage to the solar panels. At present, in order to ensure the structural integrity of solar panels in such areas, rods are usually used to reinforce the structure of solar panels. However, this design will cause the solar panels to vibrate and be damaged when subjected to strong wind pressure, and the ability to withstand strong wind pressure is limited. In addition, this structure has high redundancy, which restricts the use of solar panels.

[0032] In the relevant technology, solar panels are a device that directly converts sunlight into electrical energy. They are the core components of solar power generation systems. Solar panels use renewable resources to convert electrical energy, and their development prospects are relatively broad. In order to improve the power generation efficiency and power generation of solar panels, it is usually necessary to use multiple solar panels to form a solar project to meet the power generation needs. However, solar projects usually need to be set up in large areas such as deserts, Gobi, and oceans to meet the area requirements of solar projects. However, such areas are usually accompanied by relatively harsh environmental factors, such as strong winds. Therefore, the wind pressure resistance design of solar panels is a prerequisite for ensuring the normal use of solar panels.

[0033] At present, the commonly used wind pressure resistant design of solar panels is to increase the setting of structural rods to reinforce the solar panels. However, this structure will still cause the solar panels to vibrate and be damaged when facing strong wind pressure, and cannot provide an effective wind pressure resistant structure.

[0034] Based on this, the embodiment of the present disclosure provides a wind pressure self-unloading solar panel, such as Figure 1 As shown, combined Figures 2 to 7 The solar panel includes: a panel body 20 and a connecting device.

[0035] Among them, the board body 20 is connected to the bracket unit, and the board body 20 includes a first end 201 and a second end 202 arranged opposite to each other along the length direction, the first end 201 is connected to the first support member 101, and the second end 202 is connected to the second support member 102, the first support member 101 and the second support member 102 are parallel to each other and are not located in the same horizontal plane, so that there is a preset angle between the board body 20 and the horizontal plane.

[0036] The connecting device is arranged on the side of the plate body 20 away from the light source, including a first connecting component 310 arranged at the first end 201 and a second connecting component 320 arranged at the second end 202; the first connecting component 310 includes at least one sleeve ring structure, each sleeve ring structure includes a flat plate portion 311 and a circular ring portion 312, the flat plate portion 311 is vertically connected to the edge of the first end 201, and the circular ring portion 312 is sleeved on the first support member 101, and the plate body 20 rotates around the first support member 101 through the first connecting component 310; the second connecting component 320 includes a connecting portion 321, a limiting portion 322 and a sliding portion Rail 323, one end of the connecting portion 321 is connected to the edge of the second end 202, and the other end of the connecting portion 321 is rotatably connected to one end of the slide rail 323; the limiting portion 322 is fixedly connected to the second support member 102, and the connection point between the limiting portion 322 and the second support member 102 is located on the line connecting the second support member 102 and the first support member 101, the limiting portion 322 has a slide groove 3221, the slide rail 323 is arranged in the slide groove 3221 and slides along the slide groove 3221, the width of the two ends of the slide rail 323 is greater than the width of the slide groove 3221, and the depth of the slide groove 3221 is greater than the thickness of the slide rail 323.

[0037] The wind pressure self-unloading solar panel provided by the present disclosure is provided with a connecting device on the panel body 20. In a strong wind environment, the strong wind pressure pushes the panel body to rotate to a position where the panel body 20 is parallel to the horizontal plane through the first connecting component 310 to unload the wind pressure. During the pressure unloading process, the slide rail 323 in the second connecting component 320 slides in the slide groove 3221. Through the movement cooperation between the slide rail 323 and the slide groove 3221, the vibration of the panel body 20 in the strong wind pressure environment is reduced, thereby avoiding damage to the structure of the panel body 20. In addition, when the panel body 20 rotates to the horizontal plane position, the slide rail 32 3 is clamped in the slide groove 3221 to fix and support the panel body 20, so as to avoid damage to the panel body 20 caused by repeated oscillation and rotation of the panel body 20 due to uncertain wind direction. In a weak wind pressure environment, the panel body 20 is rotated back to its original position by its own gravity, and the other end of the slide rail 323 is clamped in the slide groove 3221 to prevent the panel body 20 from being oscillated and damaged. In addition, during the rotation of the panel body 20, the mutual cooperation of the slide rail 323 and the slide groove 3221 can also buffer the panel body 20, so as to avoid damage caused by excessive rotation speed of the panel body 20. The solar panel provided by the present disclosure can unload wind pressure by itself, does not require power element control, has a simple structure, is highly practical, and has high economic efficiency.

[0038] It should be noted that the solar panel provided by the present disclosure is arranged on a bracket unit, one end of the bracket unit is used to support the solar panel, and the other end of the bracket unit is a fixed end, such as the fixed end can be fixed on the ground or the seabed. The bracket unit can be composed of a plurality of rod structures, and the specific combination form of the plurality of rod structures can be determined according to the specific use requirements of the bracket unit. Among them, the bracket unit includes at least a first support member 101 and a second support member 102, and the first support member 101 and the second support member 102 are rod structures that directly support the solar panel. The connection method and position relationship between the first support member 101, the second support member 102 and other rod structures can be selected according to the specific design requirements of the bracket unit, which will not be described in detail here.

[0039] In the present disclosure, a plurality of solar panels can be arranged on the bracket unit at the same time. For example, a plurality of solar panels can be arranged in an array on the bracket unit to realize the simultaneous or partial conversion of solar energy by the plurality of solar panels. The specific number and layout of the solar panels on the bracket unit can be determined according to the actual use requirements, and the present disclosure does not make specific limitations. In addition, in order to improve the utilization rate of solar energy by the solar panels, a preset angle is usually required between the solar panels and the horizontal plane to meet the absorption rate and utilization rate of the solar energy by the solar panels. The preset angle can be adjusted according to factors such as the setting environment of the solar panels. For example, the preset angle can be 10°~60°, but is not limited thereto.

[0040] In some embodiments, the relative position between the solar panel and the horizontal plane may be fixed; in some embodiments, the relative position between the solar panel and the horizontal plane may be not fixed. For example, the solar panel may be adjusted to a preset angle according to the movement angle of the sun. The wind pressure self-unloading solar panel provided in the present disclosure is applicable to the positional relationship in the above embodiments.

[0041] The following will describe in detail the various parts of the wind pressure self-unloading solar panel provided by the embodiment of the present disclosure in conjunction with the accompanying drawings: In the embodiments provided in the present disclosure, Figure 1 As shown, combined Figure 2 and Figure 3 The solar panel includes a panel body 20, which is connected to the bracket unit. The panel body 20 includes a first end 201 and a second end 202 that are relatively arranged along the length direction. The first end 201 is connected to the first support member 101, and the second end 202 is connected to the second support member 102. The panel body 20 is used to convert solar energy into electrical energy.

[0042] In the present disclosure, the panel body 20 of the solar panel takes a rectangular structure as an example, but it is not limited to this. For panel bodies 20 of different shapes, the setting position of the panel body 20 on the bracket unit can be adaptively deformed, which should be understood to be within the protection scope of the present disclosure.

[0043] The first support member 101 and the second support member 102 are components that directly support the board body 20. The first support member 101 and the second support member 102 are parallel to each other and are not located in the same horizontal plane. The second end 202 of the board body is arranged lower than the first end 201, so that there is a preset angle between the board body 20 and the horizontal plane. In the embodiment provided by the present disclosure, the first position is a position where the board body 20 has a preset angle with the horizontal plane, and the second position is a position where the board body 20 is parallel to the horizontal plane.

[0044] The first support member 101 and the second support member 102 may be a cylindrical rod structure, or a cylindrical rod structure, or a rod structure partially having a cylindrical shape. In addition, the cross-section of the first support member 101 and the second support member 102 may be rectangular, square, or triangular, and the specific structure and shape of the first support member 101 and the second support member 102 may be selected according to the actual use requirements of the two.

[0045] In some embodiments, when the first support member 101 and the second support member 102 are non-cylindrical or non-columnar structures, the solar panel may further include a buffer portion, the buffer portion having a cavity, the cavity being used to accommodate the first support member 101, and the buffer portion being fixedly connected to the first support member 101. For example, when the first support member 101 is a triangular cross-section, in order to allow the panel body 20 to rotate around the first support member 101 through the first connecting assembly 310, a buffer portion may be provided between the first support member 101 and the first connecting assembly 310, the buffer portion may be cylindrical, and the first support member 101 may be fixedly connected inside the buffer portion, so that the first connecting assembly 310 and the first support member 101 may form a relative rotational motion.

[0046] In some embodiments, Figure 4 As shown, the first connecting component 310 can be directly connected to the first support member 101. If the first support member 101 is a non-cylindrical or non-columnar structure, the portion connecting the first support member 101 and the first connecting component 310 can be cut to form a cylindrical shape by cutting or other means to meet the requirement of the plate body to rotate through the first connecting component 310 and the first support member 101.

[0047] In the embodiments provided in the present disclosure, Figure 1 As shown, combined Figure 2 and Figure 3 The solar panel includes a connecting device, which is arranged on the side of the panel body 20 facing away from the light source. The connecting device includes a first connecting component 310 and a second connecting component 320. The first connecting component 310 is arranged at the first end 201 of the panel body, and the second connecting component 320 is arranged at the second end 202 of the panel body.

[0048] In some embodiments, the board body 20 may include a main body and a frame 500 surrounding the main body. Figure 6 As shown, combined Figure 1 , the connecting device is arranged on the frame 500, and the frame 500 is arranged around the main body. The shape of the frame 500 can be adapted to the shape of the main body. The arrangement of the frame 500 facilitates the assembly between the board body 20 and the bracket unit, and improves the durability of the board body 20. In some embodiments, the board body 20 includes a main body, and the connecting device is arranged on the edge of the main body. The board body 20 without a frame can improve the lightness of the device and improve the economy. Among them, the main body is a component that converts solar energy into electrical energy.

[0049] The first connection assembly 310 includes at least one ring structure. Figure 4 As shown, combined Figure 1 , each collar structure includes a flat plate portion 311 and a circular ring portion 312, the flat plate portion 311 is vertically connected to the edge of the first end 201, the circular ring portion 312 is sleeved on the first support member 101, and the panel body 20 rotates around the first support member 101 through the first connecting assembly 310. Take the first connecting assembly 310 as an example, the two collar structures are symmetrically arranged on the two long sides of the panel body 20, that is, the distance between the two collar structures is equal to the width of the panel body 20, the structures of the two collar structures can be the same or different, and the specific structures of the two collar structures can be adapted to the structures at the connection positions between them and the first support member 101; when the first support member 101 is a cylindrical or cylindrical structure, the two collar structures are the same. Of course, the number of collar structures can also be three, four or more, and the number and position relationship of the collar structures can be adaptively adjusted according to factors such as the specific size of the solar panel, which is not specifically limited in this disclosure, but it should be understood that the arrangement of the collar structure can meet the needs of the panel body 20 rotating around the first support member 101.

[0050] The first connecting component 310 includes a flat plate portion 311, which is vertically connected to the first end 201 of the plate body. The flat plate portion 311 and the plate body 20 can be fixedly connected by screwing, riveting, etc. to ensure that when the plate body 20 rotates, the plate body 20 drives the first connecting component 310 to rotate synchronously.

[0051] The first connecting assembly 310 includes an annular portion 312 , which is sleeved on the first support member 101 . The board body 20 rotates around the first support member 101 through the first connecting assembly 310 , that is, the first support member 101 can provide a rotation fulcrum for the rotation of the board body 20 .

[0052] The annular portion 312 is composed of a hollow structure and rib structures arranged on both sides of the hollow structure, and the rib structures are used to improve the structural strength of the annular portion 312. Further, in order to improve the structural strength of the sleeve structure, the annular portion 312 and the flat plate portion 311 can adopt an integral structure.

[0053] The first connecting component 310 in the connecting device provided in the present disclosure is arranged on the side of the board body 20 away from the light source, so that the board body 20 can rotate around the first support member 101 through the first connecting component 310 to change the position of the board body 20, providing a basis for subsequent pressure relief of the board body 20.

[0054] Among them, Figure 5 As shown, combined Figure 1 and Figure 6 The second connection assembly 320 includes a connection portion 321, a stop portion 322, and a slide rail 323. One end of the connection portion 321 is fixedly connected to the edge of the second end 202 of the plate body, and the other end of the connection portion 321 is rotatably connected to one end of the slide rail 323. When the plate body 20 rotates, the plate body 20 can drive the slide rail 323 to slide through the connection portion 321. In some specific embodiments, the connection portion 321 can be a hinge structure, and the connection portion 321 can realize the connection between the slide rail 323 and the plate body 20, and at the same time, the rotation of the slide rail 323 relative to the plate body can be realized to avoid the slide rail 323 from getting stuck.

[0055] The limiting portion 322 is fixedly connected to the second support member 102, and the connection point between the limiting portion 322 and the second support member 102 is located on the line connecting the second support member 102 and the first support member 101, so as to ensure that the limiting portion 322 can limit the movement trajectory of the slide rail 323, ensure the correctness of the relative position relationship between the slide rail 323 and the plate body 20, and further ensure that the plate body 20 can rotate without getting stuck.

[0056] The limiting portion 322 has a slide groove 3221, and the slide rail 323 is arranged in the slide groove 3221 and the slide rail 323 can slide along the slide groove 3221. The width of both ends of the slide rail 323 is greater than the width of the slide groove 3221. When the end of the slide rail 323 slides to the position matching with the slide groove 3221, since the width of the end of the slide rail 323 is greater than the width of the slide groove 3221, the slide rail 323 can be clamped in the slide groove 3221 to fix the position of the slide rail 323, and the slide rail 323 can provide support for the board body 20. It should be noted that the slide rail 323 is clamped in the slide groove 3221, but it is not stuck in the slide groove 3221. Under a certain external force, the slide rail 323 can be separated from the slide groove 3221 and continue to slide along the slide groove 3221.

[0057] The depth of the slide groove 3221 is greater than the thickness of the slide rail 323, so that the slide rail 323 can slide in the slide groove 3221 and can also rotate with the second support member 102 as a fulcrum, so that the position of the slide rail 323 and the position of the plate body 20 are mutually adapted to avoid the slide rail 323 and the plate body 20 from being stuck. For example, the ratio of the thickness of the slide rail 323 to the depth of the slide groove 3221 can be in the range of 30% to 80%. Within this range, it can be ensured that the slide rail 323 will not fall out of the slide groove 3221, and the adaptability of the relative position relationship between the slide rail 323 and the plate body 20 can be ensured.

[0058] The length of the slide rail 323 is at least greater than the first distance, which is the vertical distance between the first support member 101 and the second support member 102, to ensure that the board body 20 can at least rotate from the first position to the second position to achieve unloading of wind pressure by the board body 20.

[0059] The slide rail 323 also includes a middle portion 3231, which connects the two ends of the slide rail 323 respectively. At the connection between the middle portion 3231 of the slide rail and the end of the slide rail 323, the tangent extension direction of the middle portion 3231 of the slide rail is the same as the tangent extension direction of the end of the slide rail 323, ensuring the continuous connection between the middle portion 3231 of the slide rail and the two ends, thereby ensuring that the slide rail 323 can slide smoothly in the slide groove 3221 to avoid jamming or stuck. The width of the middle portion 3231 of the slide rail is equal to or less than the width of the slide groove 3221. When the middle portion 3231 of the slide rail slides into the slide groove 3221, the middle portion 3231 can pass through the slide groove 3221 smoothly without jamming. The cross-sections of the two ends of the slide rail 323 are T-shaped structures, such as Figure 6 and Figure 7 As shown, two clamping parts can be formed at the two ends of the slide rail 323 to prevent the slide rail 323 from falling out of the slide groove 3221 when sliding to the end, thereby improving the reliability of the connection device. The middle part 3231 of the slide rail provided by the present disclosure can slide smoothly in the slide groove 3221, ensuring the adaptability of the position of the slide rail 323 to the position of the plate body 20, and the slide rail 323 can also limit the rotation position of the plate body 20 through the two ends, providing an effective fixing support for the plate body 20, thereby ensuring the stability of the overall structure.

[0060] It should be noted that the cross-sections of the two ends of the slide rail 323 provided by the present disclosure are T-shaped structures. The cross-sections of the two ends of the slide rail 323 can be T-shaped in the strict sense or quasi-T-shaped. The T-shaped structures of the two ends of the slide rail 323 are to ensure the connection between the slide rail 323 and the slide groove 3221, and to prevent the slide rail 323 from falling out of the slide groove 3221. In addition, the two ends of the slide rail 323 and the middle part 3231 of the slide rail constitute the whole of the slide rail 323, and the specific lengths of the two ends of the slide rail 323 and the middle part 3231 can be divided according to specific usage requirements. The embodiments and drawings of the present disclosure are only shown for example, but do not form a specific limitation on the division of the lengths of the two ends of the slide rail 323 and the middle part 3231.

[0061] One end of the slide rail 323 is connected to the connecting portion 321. After the panel body 20 drives the connecting portion 321 to move, the connecting portion 321 simultaneously drives the slide rail 323 to slide in the slide groove 3221. Since the solar panel provided by the present disclosure can achieve unpowered pressure relief, in order to ensure that the panel body 20 can fall back from the second position to the first position, the end of the slide rail 323 away from the connecting portion 321 can also be connected to a counterweight portion 330, such as Figure 7 As shown, combined Figure 1 . In order to ensure that the counterweight 330 can maintain a naturally vertical state as the direction of the slide rail 323 changes, so that the counterweight 330 will not interfere with the structure in the bracket unit during the movement of the slide rail 323, the counterweight 330 and the slide rail 323 can be rotatably connected. For example, the counterweight 330 can be a counterweight block, and the counterweight 330 can be rotatably connected with one end of the slide rail 323 through a hinge. In addition, when the board body 20 falls back from the second position to the first position, the sum of the gravity of the board body 20 and the connecting device is greater than the thrust provided by the wind pressure, thereby realizing the fall of the board body 20. In order to ensure that the board body 20 can fall back from the second position to the first position under the condition of the preset wind force, the weight of the counterweight 330 can be greater than or equal to the sum of the weight of the board body 20 and the slide rail 323. The gravity of the counterweight 330 can further provide a falling force for the board body 20, thereby ensuring that the board body 20 can fall back smoothly.

[0062] The slide rail 323 in the connecting device provided in the present invention can control and buffer the rotation speed of the panel body 20 by cooperating with the slide groove 3221, and at the same time avoid vibration damage to the panel body 20 when the wind direction and wind force are uncertain, thereby ensuring the structural integrity of the panel body 20 and improving the service life of the solar panel.

[0063] In a specific embodiment, the limiting portion 322 may be a pulley set. Specifically, the limiting portion 322 may include a first fixed pulley 401 and a second fixed pulley 402 that are relatively arranged. The first fixed pulley 401 and the second fixed pulley 402 are respectively fixedly connected to the second support member 102. The two long sides of the slide rail 323 are respectively overlapped in the groove of the first fixed pulley 401 and the groove of the second fixed pulley 402. The first fixed pulley 401 and the second fixed pulley 402 provide a limiting effect for the sliding of the slide rail 323, thereby ensuring the adaptability of the position and movement relationship between the slide rail 323 and the plate body 20.

[0064] The first fixed pulley 401 and the second fixed pulley 402 may adopt the same structure or different structures, but in order to facilitate installation and improve the adaptability of the size and structure of the pulley block and the bracket unit, the first fixed pulley 401 and the second fixed pulley 402 usually adopt the same structure. There is a gap between the first fixed pulley 401 and the second fixed pulley 402, the groove depth of the first fixed pulley 401 is less than half of the minimum width of the slide rail 323, and the groove depth of the second fixed pulley 402 is less than half of the minimum width of the slide rail 323, that is, the width of the slide groove 3221 is the sum of the groove depth of the first fixed pulley 401, the groove depth of the second fixed pulley 402 and the gap. When the position relationship of the fixed pulleys in the pulley block meets the above conditions, the slide rail 323 can be guaranteed to slide smoothly in the slide groove 3221.

[0065] Specifically, the axis of the first fixed pulley 401 and the axis of the second fixed pulley 402 are parallel to each other, and the plane formed by the axis of the first fixed pulley 401 and the axis of the second fixed pulley 402 coincides with or overlaps with the plane formed by the first support member 101 and the second support member 102, so as to ensure that the setting positions of the first fixed pulley 401 and the second fixed pulley 402 will not interfere with the components in the bracket unit, thereby ensuring the correct positional relationship and movement relationship between the various components in the solar panel. Among them, the first fixed pulley 401 and the second fixed pulley 402 can be connected to the second support member 102 by bolts. For example, two through holes are opened on the second support member 102, and the distance between the two through holes is equal to the distance between the axes of the first fixed pulley 401 and the second fixed pulley 402. After the bolts are passed through the through holes on the second support member 102 and the through holes opened on the axis of the first fixed pulley 401 at the same time, the fixed connection between the first fixed pulley 401 and the first support member 101 is completed. The connection method of the second fixed pulley 402 on the second support member 102 is the same as that of the first fixed pulley 401, forming a fixed position of the pulley group on the second support member 102, providing a limiting effect for the sliding of the subsequent slide rail 323.

[0066] Of course, in the present disclosure, the limiting portion 322 can also be other structures with a slide groove 3221 other than the pulley block. The limiting portion 322 is a pulley block and a deformation form of the pulley block, or other structures similar to the pulley block structure and can provide a slide groove 3221 matching the slide rail 323, all of which are within the protection scope of the present disclosure.

[0067] It should be noted that, in the present disclosure, a connection device includes at least one first connection component 310 and one second connection component 320. For solar panels of different structures, multiple connection devices can be provided accordingly, and the number of first connection components 310 and second connection components 320 in the connection device can also be adaptively adjusted. In a specific embodiment, a connection device can be provided on a panel body 20, and a connection device includes a first connection component 310 and two second connection components 320. A first connection component 310 includes two collar structures, wherein the two collar structures are symmetrically arranged at the first end 201 of the panel body, and the two second connection components 320 are symmetrically arranged at the second end 202 of the panel body, that is, the first connection component 310 and the second connection component 320 are respectively arranged at the four corners of the panel body 20 to form a symmetrical structure. When the panel body 20 rotates, this structure can ensure the movement balance of the panel body 20.

[0068] In the present disclosure, except for the panel body 20, other components in the solar panel can be made of metal, for example, stainless steel, copper, aluminum and other metal materials, and these components can be anti-corrosive by anti-corrosion technology to improve the structural strength and service life of the solar panel. Among them, the anti-corrosion technology can be anti-corrosion coating, etc., which are not listed here one by one.

[0069] The connecting device provided by the present invention is interconnected with the panel body 20, so that the solar panel can achieve unpowered pressure relief. In a strong wind pressure environment, the panel body 20 is driven to rotate by wind force, and the panel body 20 drives the connecting device to move. After the panel body 20 rotates to the second position, the connecting device provides support for the panel body 20. In a weak wind pressure environment, the panel body 20 can fall back to the first position by its own gravity. At the same time, during the rotation of the panel body 20, the connecting device can control and buffer the rotation speed of the panel body 20 to avoid damage caused by excessive rotation of the panel body 20. In addition, the connecting device can also avoid vibration damage to the panel body 20 when the wind force and wind direction change, thereby ensuring the structural integrity of the solar panel and increasing the service life of the solar panel. In addition, since the unpowered source control structure adopted in the present invention unloads wind pressure on the solar panel, the structure is simple and has strong reusability and good economy.

[0070] The disclosed embodiment also provides a method for using a wind pressure self-unloading solar panel, using the solar panel in any of the above embodiments, such as Figure 8 As shown, combined Figures 1 to 7 The method of use includes: step S10 to step S30.

[0071] Wherein, step S10: installing the solar panel on the bracket unit, the panel body 20 is in a first position, and the first position is a position where a preset angle is formed between the panel body 20 and the horizontal plane; Step S20: When the wind force is greater than or equal to the preset level, the wind force drives the board body 20 to rotate and move in the direction of decreasing the preset angle, and at the same time, the board body 20 drives the slide rail 323 to move in the slide groove 3221 until the board body 20 rotates to the second position, and the end of the slide rail 323 is clamped in the slide groove 3221 to fix the board body 20 in the second position, wherein the second position is a position where the board body 20 is parallel to the horizontal plane; Step S30: When the wind force is less than the preset level, the end of the slide rail 323 disengages from the slide slot 3221, and the slide rail 323 drives the board body 20 to rotate from the second position to the first position until the board body 20 rotates to the first position, and the other end of the slide rail 323 is clamped in the slide slot 3221 to fix the board body 20 at the first position.

[0072] The method for using the wind-pressure self-unloading solar panel provided in the present disclosure can achieve unpowered pressure relief of the solar panel by using the solar panel provided in the above-mentioned embodiment, thereby improving the usability of the solar panel in different environments, especially suitable for strong wind environments, ensuring the structural integrity of the solar panel, and thus increasing the service life of the solar panel.

[0073] It should be noted that, although the steps of the method for using the wind pressure self-unloading solar panel in the present disclosure are described in a specific order in the drawings, this does not require or imply that the steps must be performed in this specific order, or that all the steps shown must be performed to achieve the desired results. Additionally or alternatively, some steps may be omitted, multiple steps may be combined into one step, and / or one step may be decomposed into multiple steps, etc.
