[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present disclosure. The terms used herein in the specification of the present disclosure are only for the purpose of describing specific embodiments and are not intended to limit the present disclosure. The term "or / and" used herein includes any and all combinations of one or more related listed items.

[0048] See also Figure 1 , Figure 1 The overall structure of the first embodiment of the photovoltaic panel structure in the embodiments of the present disclosure is shown. The present disclosure relates to the photovoltaic field, in particular to a photovoltaic panel structure and a photovoltaic system.

[0049] As the product process technology of photovoltaic modules improves and the cost decreases, photovoltaic modules can be used in more industries, such as powering agricultural greenhouses. When photovoltaic module products are used in agricultural greenhouses, there is a requirement for light transmission while ensuring power supply, so that light can irradiate the greenhouse. The photovoltaic panel structure provided in the embodiments of the present disclosure can be applied to agricultural greenhouses.

[0050] The embodiment of the present disclosure provides a photovoltaic panel structure 10, which includes a battery array 11, a fixing member 12, and a plurality of protective covers 13. The fixing member 12 is connected to the battery array 11, and the fixing member 12 includes an edge portion 121 located at the periphery of the battery array 11, and the edge portion 121 is provided with a plurality of through holes 122. The protective cover 13 is passed through the corresponding through holes 122, and the protective cover 13 includes a cover body 131 and a flange 132, and the flange 132 is located at the end of the cover body 131 and extends radially along the cover body 131. It can be understood that the inner hole of the cover body 131 is smaller than the through hole 122.

[0051] In the photovoltaic panel structure 10 provided in the embodiment of the present disclosure, the edge 121 of the fixing member 12 can be light-transmissive. By providing a through hole 122 and a protective cover 13 at the edge 121 of the fixing member 12, the method of using a pressure plate to install the fixing frame 124 can be avoided. The sleeve body 131 of the protective cover 13 is penetrated through the through hole 122, and the flange 132 extends radially along the sleeve body 131, which can reduce the wear of the through hole 122, thereby adding more installation methods.

[0052] The photovoltaic panel structure 10 can better meet the light transmission requirements and realize the diversified light transmission requirements in a flexible installation method. In addition, the photovoltaic panel structure 10 has a high integration level and can save more space.

[0053] refer to Figure 1 The fixing member 12 is a cover plate 123. The cover plate 123 is stacked on the battery array 11; the area of ​​the cover plate 123 is larger than the area of ​​the battery array 11, and the edge portion 121 of the fixing member 12 is a part of the cover plate 123. The through hole 122 penetrates the cover plate 123.

[0054] In some embodiments, the material of the fixing member 12 can be inorganic or organic high weather-resistant materials such as glass, organic glass, PET, ETFE, etc. Glass is relatively heavy, but has good light transmission and weather resistance; while organic materials are light and can be bent appropriately.

[0055] Exemplarily, the fixture 12 is a double-glass component (both the front and back surfaces of the battery array 11 are glass). In other embodiments, the fixture 12 may also be a single-glass component (the front of the battery array 11 is glass and the back is organic material), or a glassless component (both the front and back surfaces of the battery array 11 are not glass). Depending on the application environment's requirements for mechanical strength, weight, and weather resistance, the fixture 12 uses different front and back surface materials.

[0056] Exemplarily, the through hole 122 is in the shape of a circular hole. It is understandable that the shape of the through hole 122 includes but is not limited to a circular hole, an elliptical hole, and a square hole.

[0057] Exemplarily, the number of through - holes 122 on the photovoltaic panel structure 10 is four. In other embodiments, the number of through - holes 122 is not limited, as long as it can achieve the purpose of connecting or fixing the photovoltaic panel structure 10 to the support rod or an external structure. The sleeve 131 is fixed to the through - hole 122 by means of snap - connection, buckle - connection or screw - connection, etc. The external structure can be fixed or connected by means of snap - connection, buckle - connection, bolts, etc. through the sleeve 131 passing through the through - hole 122.

[0058] In some embodiments, the perforation position is 0 < X < 1 / 4L (L is the length of the long side or the short side. X refers to the distance from the center of the through - hole 122 to the edge of the long or short side). Exemplarily, the perforation position is close to the edges of the long side and the short side, which is beneficial to more light projection and the stability of the installation of the photovoltaic panel assembly. Exemplarily, it includes four through - holes 122 located at the four corners of the rectangular photovoltaic panel structure 10.

[0059] Refer to Figure 5 , Figure 5 shows the overall structure of the protective sleeve 13 in the embodiments of the present disclosure. Exemplarily, the protective sleeve 13 is made of rubber. In other embodiments, the protective sleeve 13 can also be made of other materials such as plastic, metal, etc., as long as it can achieve the purpose of protecting the fixing member 12.

[0060] Exemplarily, at least one layer of the front and back surfaces of the photovoltaic panel structure 10 uses a concave - convex structure. For example, an embossed / acid - etched glass (pitted surface) is placed on one surface of the photovoltaic module. By increasing light scattering, the uniformity of the transmitted light is improved.

[0062] With such a setting, the cover plate 123 is beneficial to the fixation of the battery array 11 and improves the mechanical strength of the photovoltaic panel structure 10. The through - hole 122 penetrating through the cover plate 123 can increase the installation methods of the photovoltaic panel structure 10 and achieve diverse light - transmission requirements.

[0063] Refer to Figure 2The fixing member 12 includes a cover plate 123 and a frame 124. The cover plate 123 is stacked on the battery array 11, and the frame 124 is surrounded by the cover plate 123; the area of ​​the cover plate 123 is larger than the area of ​​the battery array 11, and the edge portion 121 of the fixing member 12 is a part of the frame 124.

[0064] Exemplarily, the frame 124 is surrounded on three sides at the edges of the cover plate 123 , and the frame 124 is surrounded on the edges of two long sides of the cover plate 123 . The through hole 122 passes through the cover plate 123 .

[0066] Exemplarily, the frame 124 is surrounded by the cover plate 123 on three sides, the frame 124 is surrounded by the edges of the two long sides of the cover plate 123, and the through hole 122 penetrates both the cover plate 123 and the frame 124. It can be understood that the photovoltaic panel structure 10 also includes a fastener 21, which passes through the through hole 122 to lock the cover plate 123 and the frame 124 to prevent the two from separating.

[0067] In other embodiments, the frame 124 may be enclosed at the edges of four sides of the cover plate 123 , or the frame 124 may be enclosed at the edges of two short sides of the cover plate 123 .

[0068] refer to Figure 3 The fixing member 12 includes a cover plate 123 and a frame 124. The cover plate 123 is stacked on the battery array 11, and the frame 124 is stacked on the cover plate 123; the area of ​​the cover plate 123 is larger than the area of ​​the battery array 11, and the edge portion 121 of the fixing member 12 is a part of the frame 124.

[0069] Exemplarily, the frame 124 is stacked on the lower surface at the edge of the cover plate 123 and the frame 124 is stacked on the lower surface at the edges of four sides of the cover plate 123. The through hole 122 penetrates the cover plate 123.

[0070] Exemplarily, the frame 124 is stacked on the lower surface at the edge of the cover plate 123 and the frame 124 is stacked on the lower surface at the edges of four sides of the cover plate 123. The through hole 122 passes through the frame 124.

[0071] Exemplarily, the frame 124 is stacked on the lower surface at the edge of the cover plate 123 and the frame 124 is stacked on the lower surface at the edges of the four sides of the cover plate 123. The through hole 122 penetrates both the cover plate 123 and the frame 124. It can be understood that the photovoltaic panel structure 10 also includes a fastener 21, which passes through the through hole 122 to lock the cover plate 123 and the frame 124 to prevent the two from separating.

[0072] In other embodiments, the frame 124 may be stacked on the lower surface of the edges of the two long sides of the cover plate 123 , or the frame 124 may be stacked on the lower surface of the edges of the two short sides of the cover plate 123 .

[0073] It is understandable that the contact portion between the cover plate 123 and the frame 124 may be provided with materials such as silicone, flexible rubber, etc. to avoid rigid contact.

[0074] See also Figure 4 , Figure 4 The overall structure of the fourth embodiment of the photovoltaic panel structure 10 in the embodiments of the present disclosure is shown. In some embodiments, the fixing member 12 includes a cover plate 123 and a frame 124, the cover plate 123 is stacked on the battery array 11, the area of ​​the cover plate 123 is larger than the area of ​​the battery array 11, and the cover plate 123 is located in the frame 124; the through hole 122 passes through the cover plate 123 and / or the frame 124.

[0075] In this configuration, the cover plate 123 is located within the frame 124, which is beneficial to fix the battery array 11 and improves the mechanical strength of the photovoltaic panel structure 10. The through hole 122 passes through the cover plate 123 and the frame 124, which can increase the installation methods of the photovoltaic panel structure 10 and meet various light transmission requirements.

[0076] Exemplarily, the frame 124 has a wider extension, and the four sides of the cover 123 are all located within the frame 124, so that the cover 123 is not provided with a through hole 122 but the frame 124 is provided with a through hole 122, and is connected or fixed to the external structure through the through hole 122 of the frame 124.

[0077] Exemplarily, the frame 124 is narrow in extension, and the four sides of the cover plate 123 are all located within the frame 124 . The cover plate 123 and the frame 124 are both provided with through holes 122 to be connected or fixed to the external structure.

[0078] Exemplarily, the frame 124 is narrow in extension, and the four sides of the cover plate 123 are all located within the frame 124, so that the frame 124 is not provided with a through hole 122 while the cover plate 123 is provided with a through hole 122 to connect or fix with the external structure.

[0079] In some embodiments, the photovoltaic panel structure 10 further includes a connecting ring 14 , and a portion of the connecting ring 14 is passed through the protective cover 13 , so that the connecting ring 14 is hung on the fixing member 12 .

[0080] With such arrangement, the connection ring 14 can extend the connection structure, and the installation method of the photovoltaic panel structure 10 can be set according to the distance requirements to achieve various light transmission requirements.

[0081] For example, a part of the rope can be passed through the protective cover 13 so that the rope is hung on the fixing member 12. It is understandable that the fixing member 12 can be connected or fixed to the external structure by passing through the protective cover 13 in various ways such as buckling, clamping, and bolting.

A portion of the third connecting cable 90 is passed through the fourth through hole 1022 of the second photovoltaic panel structure 102, and the third connecting cable 90 is connected to the slider 130.

[0084] In the photovoltaic system 100 provided by the embodiment of the present disclosure, the first photovoltaic panel structure 101 and the second photovoltaic panel structure 102 are connected by the second connecting rope 80, which is conducive to setting a retractable device, so as to facilitate the adjustment of the spacing between the multiple photovoltaic panel structures 10 after the photovoltaic system 100 is installed. The slider 130 can drive the first photovoltaic panel structure 101 and the second photovoltaic panel structure 102 to change their positions along the first direction, so as to facilitate the unfolding and folding of the photovoltaic panel structure 10, and improve the control and utilization of the projected light by the photovoltaic system 100.

[0085] Exemplarily, the first connecting rope 70, the second connecting rope 80 and the third connecting rope 90 are all connected by loops, and the number of loops is not limited and is determined according to the light transmittance requirement. In other embodiments, the first connecting rope 70, the second connecting rope 80 and the third connecting rope 90 are all connected by ropes. It is understandable that the first connecting rope 70, the second connecting rope 80 and the third connecting rope 90 can be connected by ropes without loops at the same time.

[0086] Exemplarily, the photovoltaic system 100 further includes a third photovoltaic panel structure 10 , a fourth photovoltaic panel structure 10 or more photovoltaic panel structures 10 , and the plurality of photovoltaic panel structures 10 are connected by a plurality of connecting cables to form a photovoltaic assembly string.

[0087] Exemplarily, the motor drives the slider 130 to move the photovoltaic panel structure 10 along the first direction. In other embodiments, the slider 130 may be driven by a cylinder, manually, or in other ways.

[0088] In some embodiments, the photovoltaic system 100 further includes a second frame 120 and a sliding rope 140, wherein the second frame 120 is spaced apart from the first frame 110 along the first direction, and the sliding rope 140 is slidably connected to the first frame 110 along the first direction. The slider 130 is located between the first frame 110 and the second frame 120, and the slider 130 is fixed to the sliding rope 140. The first connecting rope 70 and the third connecting rope 90 are hung on the sliding rope 140, respectively.

[0089] With such arrangement, the sliding rope 140 can easily drive the slider 130 to slide, and the sliding rope 140 occupies a small space and has a light weight, and has a simple structure and low cost.

[0090] Exemplarily, the material of the sliding rope 140 can be a metal material such as steel wire, or a hemp rope material composed of plant fibers.

[0091] Exemplarily, the sliding rope 140 is a transparent rope made of an organic material, which helps more sunlight to pass through the sliding rope 140 .

[0092] In some embodiments, the photovoltaic system 100 includes two parallel sliding ropes 140, two corresponding first connecting ropes 70, and two corresponding third connecting ropes 90. The first photovoltaic panel structure 101 includes two corresponding first through holes 1011, and the second photovoltaic panel structure 102 includes two corresponding fourth through holes 1022. The photovoltaic system 100 also includes a guide 150, which is used to guide one of the two sliding ropes 140, and the guide 150 is slidably connected to the first rack 110 around the other of the two sliding ropes 140.

[0093] In this way, the two sliding ropes 140, the two first connecting ropes 70 and the corresponding two through holes 122 improve the stability and balance of the sliding connection of the photovoltaic panel structure 10. The setting of the guide 150 is conducive to the change of the angle between the first photovoltaic panel structure 101 and the second photovoltaic panel structure 102, which is conducive to the shielding or projection of light.

[0094] Exemplarily, the guide member 150 is a rolling track, the radius of the arc of the rolling track is the distance between two sliding ropes 140, one of the sliding ropes 140 passes through a position of the rolling track, and the rolling track is driven by a motor to drive the sliding rope 140 to move in a direction perpendicular to the first direction to achieve the tilt of the photovoltaic panel assembly.

[0095] Exemplarily, there may be two guide members 150 , and two sliding ropes 140 may be guided simultaneously to change the tilt direction of the photovoltaic panel assembly.

[0097] In this way, the retraction and extension of the limit rope 160 can control the position change of the first photovoltaic panel structure 101 and the second photovoltaic panel structure 102, so that the photovoltaic panel structure 10 assembly moves as a whole, which is conducive to the complete unfolding and folding of the photovoltaic panel structure 10 assembly, and improves the control and utilization of the projected light by the photovoltaic system 100. For example, the material of the limit rope 160 can be a metal material such as steel wire, or a hemp rope material composed of plant fibers.

[0098] Exemplarily, the limiting rope 160 is a transparent rope made of an organic material, which helps more sunlight to pass through the limiting rope 160 .

The fixing method can be knotting or fixing with a fixing piece. The portion of the first connecting rope 70 that does not pass through the first through hole 1011 is connected to the sliding rope 140, and one end of the sliding rope 140 connected to the first connecting rope 70 is connected to the guide 150, and the slider 130 is fixedly connected to the other end of the sliding rope 140.

[0102] When the left motor gradually tightens the sliding rope 140, the right motor gradually releases the sliding rope 140, and the limiting rope 160 is fixedly connected to the first rack 110, the first photovoltaic panel structure 101 of the first group of photovoltaic components is still located close to the first rack 110, the slider 130 moves along the first direction following the sliding rope 140, the first connecting rope 70, the second connecting rope 80 and the third connecting rope 90 are gradually opened, and the second photovoltaic panel structure 102 of the first group of photovoltaic components gradually moves away from the first rack 110, and an acute angle is formed between the battery array 11 of the first photovoltaic panel structure 101 and the battery array 11 of the second photovoltaic panel structure 102, and the angle gradually increases, and the photovoltaic component string is in a semi-extended state.

[0103] When the left motor completely tightens the sliding rope 140, the right motor completely releases the sliding rope 140, and the limiting rope 160 is fixedly connected to the first rack 110, the first photovoltaic panel structure 101 of the first group of photovoltaic components is still located near the first rack 110, and the slider 130 follows the sliding rope 140 to move along the first direction to a position close to the second rack 120, the first connecting rope 70, the second connecting rope 80 and the third connecting rope 90 are all in a tensioned state, the distance between the second photovoltaic panel structure 102 of the first group of photovoltaic components and the first rack 110 becomes farther, and the second photovoltaic panel structure 102 of the third group of photovoltaic components is located near the second rack 120, the angle between the battery array 11 of the first photovoltaic panel structure 101 and the battery array 11 of the second photovoltaic panel structure 102 is 180°, the first photovoltaic panel structure 101 and the second photovoltaic panel structure 102 are both parallel to the ground, and the photovoltaic component string is in an unfolded state.

[0104] See also Fig.11 , the right side of the figure is the first rack 110, and the left side is the second rack 120. Exemplarily, when the photovoltaic system 100 is in the unfolded state, the sliding rope 140 connected to one end of the first rack 110 is loosened, and the limiting rope 160 connected to one end of the first rack 110 is loosened at the same time, and the sliding rope 140 connected to one end of the second rack 120 is tightened, and the photovoltaic assembly string moves toward the second rack 120 as a whole.

[0105] Exemplarily, when the photovoltaic system 100 is in the deployed state, the slide rope 140 connected to one end of the second rack 120 is loosened, and at the same time, the limit rope 160 connected to one end of the first rack 110 is loosened, and the slide rope 140 connected to one end of the first rack 110 is tightened, and the photovoltaic component string moves as a whole toward the direction of the first rack 110.

[0107] See also Figure 12 to Figure 14 , Fig.12 is a schematic diagram of the overall structure of a second embodiment of a photovoltaic system 100 in an embodiment of the present disclosure; Fig.13 The second embodiment of the photovoltaic system 100 in the embodiment of the present disclosure is a schematic diagram of the back structure. The second embodiment of the photovoltaic system 100 in the embodiment of the present disclosure is arranged on the top 300 or the side of the greenhouse 1000 (it can also be arranged under the roof of the greenhouse 1000. The arrangement outside the greenhouse 1000 mainly considers that the light intensity is more stable, but the wind load requirement is higher than that inside the greenhouse 1000).

[0108] The disclosed embodiment provides a photovoltaic system 100, which includes the photovoltaic panel structure 10, the adapter assembly 20, the first power device 30 and the bracket 40. The adapter assembly 20 includes a buckle 21 and a support member 22, and the buckle 21 is used to lock the support member 22 with the protective cover 13 of the photovoltaic panel structure 10. The first power device 30 is used to drive the adapter bar to rotate around the axis of the first power device 30. The first power device 30 is adjustably connected to the bracket 40.

[0109] In the photovoltaic system 100 provided in the embodiment of the present disclosure, the first power device 30 drives the photovoltaic panel structure 10 to rotate so that the angle and position of the photovoltaic panel structure 10 change, thereby changing the intensity of light projected by the photovoltaic panel structure 10 and changing the transmittance of the photovoltaic structure.

[0110] Exemplarily, a driving member is provided on the bracket 40 to drive the first power device 30 to move left and right on the bracket 40. In other embodiments, a driving member can be provided on the first power device 30 to enable itself to move left and right on the bracket 40.

[0111] Exemplarily, the first power device 30 drives the photovoltaic panel structure 10 to rotate while moving on the bracket 40. When maximum shading is required, the light-receiving surface of the photovoltaic panel structure 10 is perpendicular to the incident light, and when minimum shading is required, the light-receiving surface of the photovoltaic panel structure 10 is parallel to the incident light. It is understandable that on this basis, the position between the arrangement bracket 40 and the greenhouse 1000 frame can be calculated according to the local light angle, such as the design of overlapping shadows between the two, to reduce the impact of the setting of the bracket 40 on the maximum light condition.

[0112] In some embodiments, the photovoltaic system 100 also includes a platform 50 and a second power device 60, and the bracket 40 is adjustably connected to the platform 50 through the second power device 60; the first power device 30 and the bracket 40 are located on the backlight side of the photovoltaic panel structure 10, and the first power device 30 is connected to the center position of the photovoltaic panel structure 10.

[0113] In this way, the second power device 60 drives the bracket 40 to move on the platform 50, enriching the movement scheme of the photovoltaic panel structure 10 on the platform 50, reducing the influence of the lighting conditions of the bracket 40, and further improving the change of the light transmittance of the photovoltaic structure. The first power device 30 and the bracket 40 are located on the backlight side of the photovoltaic panel structure 10 to increase the light transmittance of the photovoltaic panel structure 10, and the first power device 30 is connected to the center position of the photovoltaic panel structure 10 to improve the balance of the photovoltaic panel structure 10 during installation.

[0114] Exemplarily, a driving member is provided on the platform 50 to drive the second power device 60 to move left and right on the bracket 40. In other embodiments, a driving member can be provided on the second power device 60 to enable itself to move left and right on the platform 50.

[0115] Exemplarily, the second power device 60 drives the bracket 40 to rotate while moving on the platform 50, and the first power device 30 drives the photovoltaic panel structure 10 to rotate while moving on the bracket 40, so as to change the area and position of the shading, thereby making the movement and rotation scheme of the photovoltaic panel structure 10 more diverse, and realizing the two-stage movement and rotation of the photovoltaic panel structure 10.

[0116] In other embodiments, the first power device 30 and the bracket 40 may be located on the side of the photovoltaic panel structure 10 .
