Description

Technical Field

[0001] The present application relates to the technical field of photovoltaic equipment, and in particular to a photovoltaic bracket and a photovoltaic system. Background Art

[0002] With the development of photovoltaic technology, in order to support photovoltaic modules to resist the wind attraction generated by wind loads on photovoltaic modules, it is necessary to use related support devices for supporting photovoltaic modules. However, the manufacturing and installation processes of related support devices are complicated, which leads to high manufacturing and installation costs of the support devices and difficulty in installation. Therefore, how to provide a support for photovoltaics that is easy to install, low in cost and reliable is a technical problem that needs to be solved in photovoltaic equipment technology. Summary of the invention

[0003] Based on this, the present application provides a photovoltaic bracket and a photovoltaic system, which can facilitate installation and reduce costs while supporting photovoltaic components.

[0004] In the first aspect, the embodiment of the present application provides a photovoltaic bracket, including a bracket body and a counterweight. The bracket body is configured as an integrally formed part, including a support portion and two supporting portions. The support portion includes two first supporting walls arranged opposite to each other along a first direction, and a second supporting wall connecting the two first supporting walls. The two first supporting walls and the second supporting wall define a receiving groove, and the second supporting wall is used to be placed on the roof. The two supporting portions are used to support two photovoltaic modules adjacent to each other along the first direction in a one-to-one correspondence, and the two supporting portions are connected to the ends of the two first supporting walls facing away from the second supporting wall in a one-to-one correspondence, and the two supporting portions are respectively located on the sides of the two first supporting walls facing away from each other. The counterweight is at least partially disposed in the receiving groove. The second supporting wall can abut against the roof in response to the pressure of the counterweight. Among them, the end of the first supporting wall connected to the second supporting wall is the first end, and the end of the first supporting wall facing away from the second supporting wall is the second end. The first direction is parallel to the roof, and the first direction and the roof are both perpendicular to the direction from the first end to the second end.

[0005] In one embodiment, along the direction from the first end to the second end, the distance between the second end of the first support wall and the roof is H1, and the vertical distance between the top of the side surface of the counterweight away from the second support wall and the roof plane is H2; wherein H1>H2; and / or

[0006] Along the direction from the first end to the second end, the distance between the side surface of the counterweight away from the second supporting wall and the roof is H2, and the distance between the bottom end of the photovoltaic module and the roof is H3; wherein H3>H2.

[0007] In one embodiment, along the direction from the first end to the second end, the distance between the second end of the first support wall and the roof surface is H1, and the vertical distance between the top of the counterweight and the roof plane is H2; wherein, 2.5 ≤ H1 / H2 ≤ 3.

[0008] In one embodiment, the counterweight has a first side facing one of the first support walls and a second side facing the other first support wall; at least one of the first side and the second side is in contact with the corresponding first support wall facing it; and / or

[0009] Along the direction from the first end to the second end, the distance between the second end of one of the first support walls and the roof surface is greater than the distance between the second end of the other first support wall and the roof surface; the supporting portion has a starting end connecting the corresponding second end and a terminating end extending in a direction away from the first support wall to which the supporting portion is connected; the supporting portion connecting the second end of one of the first support walls is defined as the first target portion, and the supporting portion connecting the second end of the other second support wall is defined as the second target portion. The terminating end of the first target portion is closer to the roof surface than the starting end of the first target portion, and the starting end of the second target portion is closer to the roof surface than the terminating end of the second target portion.

[0010] In one embodiment, the thickness of the bracket body is 5 mm to 6 mm; and / or

[0011] The length of the second support wall is 10 mm to 450 mm.

[0012] In one embodiment, the photovoltaic bracket further includes a mounting member for fixing both ends of the photovoltaic module to the corresponding supporting portion.

[0013] In one embodiment, the supporting portion has a starting end connecting the corresponding second end and a terminating end extending in a direction away from the first support wall to which the supporting portion is connected;

[0014] The mounting member includes a pressing member and a fastening member. The pressing member includes a first pressing wall, a second pressing wall, and a third pressing wall. The first pressing wall and the second pressing wall are spaced apart in a direction perpendicular to the direction from the starting end to the terminating end. The third pressing wall connects the first pressing wall and the second pressing wall. The first pressing wall is used to abut against the top surface of the photovoltaic module facing away from the second support wall, the second pressing wall abuts against the surface of the supporting portion facing away from the second support wall, and the third pressing wall is used to abut against the side wall of the photovoltaic module extending in the direction perpendicular to the direction from the starting end to the terminating end;

[0015] The fastening member connects the second pressing wall and the supporting portion.

[0016] In a second aspect, an embodiment of the present application provides a photovoltaic system, including the photovoltaic support in any of the above embodiments, and a plurality of photovoltaic modules. All the photovoltaic modules are arranged in rows along a first direction and in columns along a second direction. The second direction is perpendicular to the first direction, and both the first direction and the second direction are parallel to the roof surface. Wherein, along the first direction, two adjacent photovoltaic modules are connected by means of at least one photovoltaic support. The photovoltaic module located at the most upstream along the first direction is defined as the first photovoltaic module, and the photovoltaic module located at the most downstream along the first direction is defined as the second photovoltaic module. The first photovoltaic module has a first side facing away from the second photovoltaic module, and the second photovoltaic module has a second side facing away from the first photovoltaic module. The first side of the first photovoltaic module is correspondingly connected to at least one photovoltaic support, and the second side of the second photovoltaic module is correspondingly connected to at least one photovoltaic support.

[0017] In one embodiment, along the first direction, two adjacent photovoltaic modules are connected by means of two photovoltaic supports; and / or

[0018] The first side of the first photovoltaic module is correspondingly connected to two photovoltaic supports; and / or

[0019] The second side of the second photovoltaic module is correspondingly connected to two photovoltaic supports.

[0020] In one embodiment, along the second direction, two adjacent bracket bodies form a bracket body group. The bracket bodies in different bracket body groups are different. Parts of the same counterweight are accommodated in the receiving grooves of the two bracket bodies in the same bracket body group.

[0021] In the above-mentioned photovoltaic support and photovoltaic system, the photovoltaic support at least includes a support body and a counterweight. By configuring the support body as an integrally formed part, it can have better support strength while being able to better resist external forces. By configuring the support body to include a support portion and two supporting portions, and making the support portion define a receiving groove, when part or all of the counterweight is placed in the receiving groove, not only can the second support wall of the support portion be in close contact with the roof under the pressure exerted by the counterweight, but also the contact friction force between the second support wall and the roof is increased, thereby making the entire photovoltaic support less likely to topple. At the same time, since the second support wall can be in contact with the roof in response to the pressing of the counterweight, the center of gravity of the entire photovoltaic support can be reduced. A lower center of gravity makes it more difficult for wind or external forces to cause the photovoltaic module to rotate or tip over around a certain point, and the anti-overturning ability is stronger, increasing the overall balance of the photovoltaic support. Further, since the first support wall extends in a direction perpendicular to the roof, compared with the case where the direction from the first end to the second end of the first support wall is not perpendicular to the roof, the same required height of the first support wall can be achieved with the least amount of material. At this time, the distance between the first end and the second end of the first support wall is smaller, and the first support wall is also more stable and less likely to shake. In addition, since the support body of the photovoltaic support generally forms a right-angle structure, it has a certain support strength and is also more convenient for production and processing. Thus, in the embodiments of the present application, based on the fact that the first support wall is not easily shaken, only by pressing the second support wall to the roof with a counterweight block, it is not only convenient for installation, but also can further improve the anti-overturning ability of the overall photovoltaic support.

[0034] To make the above objects, features, and advantages of the present application more obvious and understandable, the specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to facilitate a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present application.

[0036] In addition, if the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of such features. In the description of this application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

[0037] In this application, unless otherwise clearly specified and defined, if terms such as "installed", "connected", "joined", "fixed", etc. appear, these terms should be understood in a broad sense.

If an element is considered to be "connected" to another element, it can be directly connected to the other element or there may be an intermediate element at the same time. If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for illustrative purposes and do not represent the only implementation.

[0040] Currently, from the perspective of the development of the market situation, the application of photovoltaic modules is becoming more and more widespread. In order to fix the photovoltaic module to the required position, the support device is an essential part in the field of photovoltaic equipment. The support device can support the photovoltaic module to the required position by adjusting the height and installation angle.

[0041] However, the manufacturing process and installation process of the related support devices are complex, which in turn leads to high manufacturing costs and installation costs of the support devices, difficult installation, and unstable structures. Therefore, how to provide a support device for supporting photovoltaic that is easy to install, low-cost, and reliable is an urgent technical problem in the photovoltaic equipment technology.

[0042] Based on this, the embodiments of the present application provide a photovoltaic bracket to facilitate installation and reduce costs while supporting photovoltaic modules.

[0043] Refer to Figure 1 , Figure 1 shows a front view schematic diagram of the photovoltaic bracket 100 in some embodiments of the present application. The photovoltaic bracket 100 provided by an embodiment of the present application includes a bracket body 110 and a counterweight G.

[0044] "Bracket" refers to a structure used to support an object, and "body" refers to the main body or basic part of the structure. Here, the "bracket body 110" refers to the main part used to support the photovoltaic structure. The "counterweight G" refers to the weight added to balance or stabilize the structure. The bracket body 110 is configured as an integrally formed part. "Integrally formed" means a single-piece component formed by an integrally formed process with the same material. The integrally formed part has no seams or connection points and can better resist external forces, and the bracket body 110 has better support strength. In the actual production process, in a cold-working plate-making machine, the flat steel is bent into a specific shape by mechanical force, and the whole process is continuous without subsequent assembly or welding, which simplifies the production process and reduces the production cost.

[0045] Continue to refer to Figure 1 , the bracket body 110 includes a support portion 1101 and two supporting portions 1102. The support portion 1101 is a component used to support the photovoltaic module 200 to the required angle and required height here. The supporting portion 1102 refers to the component that supports the photovoltaic module 200.

[0046] The support portion 1101 includes two first support walls b1 oppositely arranged along the first direction F1 and a second support wall b2 connecting the two first support walls b1. The two first support walls b1 and the second support wall b2 define a receiving groove R, where the second support wall b2 is used to be placed on the roof surface.

[0047] The angle between the surface of the first support wall b1 extending away from the second support wall b2 and the surface of the second support wall b2 extending in the first direction F1 can be an acute angle or a right angle. According to the different angles above and according to the length relationship between the first support wall b1 and the second support wall b2, the shape of the receiving groove R in the cross-section parallel to the first direction and the second direction can be a parallelogram, a rectangle, a rhombus or a square.

[0048] The two supporting parts 1102 are used to support two photovoltaic modules 200 adjacent to each other along the first direction F1 in a one-to-one correspondence. The two supporting parts 1102 are connected to one end of the two first supporting walls b1 away from the second supporting wall b2 in a one-to-one correspondence. The two supporting parts 1102 are respectively located on the side of the two first supporting walls b1 away from each other. The counterweight G is at least partially disposed in the receiving groove R, and the second supporting wall b2 can abut against the roof in response to the pressure of the counterweight G.

[0049] The counterweight G increases the downward pressure of the second support wall b2 by its own weight, so that the friction force in the contact area between the second support wall b2 and the roof increases, thereby making the photovoltaic bracket 100 less likely to fall over as a whole, and the second support wall b2 can contact the roof in response to the pressure of the counterweight G, thereby lowering the center of gravity of the entire photovoltaic bracket 100. The lower center of gravity makes it more difficult for wind or external force to cause the photovoltaic assembly 200 to rotate or flip around a certain point, and the anti-overturning ability is stronger, thereby increasing the overall balance of the photovoltaic bracket 100. The two supporting parts 1102 are connected to the ends of the two first support walls b1 that are away from the second support wall b2 in a one-to-one correspondence, and the two supporting parts 1102 are respectively located on the sides of the two first support walls b1 that are away from each other, leaving space above the notch of the receiving groove R, so as to facilitate the placement or removal of the counterweight G into or out of the receiving groove R.

[0050] The end of the first support wall b1 connected to the second support wall b2 is the first end d1, and the end of the first support wall b1 away from the second support wall b2 is the second end d2. The first direction F1 is parallel to the roof, and the first direction F1 and the roof are perpendicular to the direction from the first end d1 to the second end d2.

[0051] Continue reading Figure 1 , the first direction F1 in the figure is the direction in which the two first support walls b1 are arranged relative to each other. The direction from the first end d1 to the second end d2 can be defined as a third direction F3, such as Figure 1 As shown in , the first direction F1 and the third direction F3 are perpendicular to each other. It can be understood that the first direction F1 and the third direction F3 are only for the convenience of description, and are not intended to limit the embodiments of the present application.

[0052] Thus, the photovoltaic support 100 forms a right-angle frame for the case where the cross-sectional shape of the above-mentioned receiving groove R in the directions parallel to the first direction and the second direction is square. The photovoltaic module 200 needs to be supported at a certain distance from the roof according to actual requirements. Since the first support wall b1 extends in the direction perpendicular to the roof, compared with the case where the direction from the first end d1 to the second end d2 of the first support wall b1 is not perpendicular to the roof, the first support wall b1 can reach the same required height with the least amount of material. At this time, the distance between the first end d1 and the second end d2 of the first support wall b1 is smaller, and the first support wall b1 is also more stable and not prone to shaking. Moreover, the overall photovoltaic support 100 forms a right-angle structure, which is also more convenient for production and processing. According to the above, the first support wall b1 is not prone to shaking, and the counterweight G only needs to press the second support wall b2 against the ground to enable the photovoltaic support 100 to have better anti-overturning ability. In the design of this application, the center of gravity of the counterweight G is lower, further improving the anti-overturning ability of the overall photovoltaic support 100. Since the second support wall b2 extends in the first direction F1 and is placed on the ground, the counterweight G only needs to be placed on the second support wall b2 to achieve counterweight, without using the mounting member 120 and without damaging the roof and the photovoltaic support 100. And at this time, the formed receiving groove R is square in the cross-section perpendicular to the roof, which is more convenient for the counterweight G to be put in or taken out.

[0053] In some embodiments of the present application, please continue to refer to Figure 1 and in combination with referring to Figure 2a and Figure 2b , Figure 2a which is Figure 1 the partial enlarged view of the A position in Figure 2b and is also Figure 1 the partial enlarged view of the A position in . Along the direction from the first end d1 to the second end d2 (i.e., the third direction F3), the distance (i.e., the first distance) between the second end d2 of the first support wall b1 and the roof is H1, and the vertical distance (i.e., the second distance) between the top of the surface of the counterweight G facing away from the second support wall b2 and the roof plane is H2, where H1 > H2; and / or, along the direction from the first end d1 to the second end d2, the distance (i.e., the second distance) between the surface of the counterweight G facing away from the second support wall b2 and the roof is H2, and the distance (i.e., the third distance) between the bottom end of the photovoltaic module 200 and the roof is H3; where H3 > H2.

[0054] Since the first distance H1 is greater than the second distance H2, the distance H1 between the second end d2 of the first support wall b1 and the roof is greater than the vertical distance H2 between the top of the surface of the counterweight G facing away from the second support wall b2 and the roof plane. The counterweight G is completely within the receiving groove R and there is no part exceeding the opening of the receiving groove R. The counterweight G will not block the operator's line of sight for construction, facilitating the operator to install the photovoltaic module 200.

[0055] Since the third distance H3 is set to be greater than the second distance H2, in the third direction F3, the end of the photovoltaic module 200 is supported as far as possible away from the second support wall b2, reducing the risk of the counterweight G blocking the photovoltaic module 200 and enhancing the effect of the photovoltaic module 200 absorbing solar energy.

[0056] When the supporting part 1102 is the first target part T1, the third distance H3 is less than the first distance H1. from At this time, the difference between the second distance H2 and the first distance H1 should be set large enough so that the third distance H3 is greater than the second distance H2. When the supporting part 1102 is the second target part T2, the third distance H3 is greater than the first distance H1. At this time, since H1 > H2, the third distance H3 must be greater than the second distance H2.

[0057] In some embodiments of the present application, continue to refer to Figure 2a and Figure 2b , along the direction from the first end d1 to the second end d2, the distance between the second end d2 of the first support wall b1 and the roof surface is H1, and the vertical distance between the top of the counterweight G and the roof surface plane is H2; wherein, 2.5 ≤ H1 / H2 ≤ 3.

[0058] As known above, it is necessary to set the first distance H1 > the second distance H2, and the difference between the first distance H1 and the second distance H2 should not be too large. If the difference is too large, the first support wall b1 may be unstable and shake when the wind blows strongly. If the difference is too small, the above-mentioned problem of inconvenient installation may occur. Therefore, H1 / H2 is selected as 2.5 ≤ H1 / H2 ≤ 3, which can not only ensure the strong self-stability of the first support wall b1 and not easy to shake, but also facilitate the installation of the photovoltaic module 200. When H1 / H2 is 2.5, it can adapt to the situation where the weight of the photovoltaic module 200 is about 20 kg. When H1 / H2 is 3, it can adapt to the situation where the weight of the photovoltaic module 200 is 15 kg. The specific parameter selection of H1 / H2 can be actually selected according to the specific weight of the photovoltaic module 200, and no limitation is made here.

[0059] In some embodiments of the present application, please continue to refer to Figure 1 and Figure 2a and Figure 2b and refer to in combination Figure 3 , Figure 3The figure is a front view schematic diagram of the photovoltaic support 100 in some other embodiments of the present application. The counterweight G has a first side C1 facing one of the first support walls b1 and a second side C2 facing the other first support wall b1; at least one of the first side C1 and the second side C2 is in contact with the corresponding first support wall b1 facing it; and / or, along the direction from the first end d1 to the second end d2, the distance between the second end d2 of one of the first support walls b1 and the roof is greater than the distance between the second end d2 of the other first support wall b1 and the roof; the supporting portion 1102 has a starting end connecting the corresponding second end d2 and a terminating end extending in a direction away from the first support wall b1 to which the supporting portion 1102 is connected; the supporting portion 1102 connecting the second end d2 of one of the first support walls b1 is defined as the first target portion T1, and the supporting portion 1102 connecting the second end d2 of the other second support wall b2 is defined as the second target portion T2. The terminating end z2 of the first target portion T1 is closer to the roof than the starting end q1 of the first target portion T1, and the starting end q2 of the second target portion T2 is closer to the roof than the terminating end z2 of the second target portion T2.

[0060] The counterweight G is abutted against the first support wall b1, and the side surfaces of the counterweight G and the first support wall b1 are in mutual abutment. When the first support wall b1 shakes or has a tendency to shake, relative sliding or a tendency of relative sliding will occur between the side surfaces of the counterweight G and the first support wall b1, and friction can be generated between the two to hinder the shaking of the first support wall b1. Moreover, the side surfaces of the counterweight G and the first support wall b1 are in mutual abutment, which can support the inner side surface of the first side wall.

[0061] It can be understood that at least one side surface being in contact with the first support wall b1 can be the case where the first side C1 is in contact with the first support wall b1, the case where the second side C2 is in contact with the first support wall b1, or the case where both the first side C1 and the second side C2 are in contact with the second side wall.

[0062] With such a design, a difference is provided in the starting ends of the two supporting portions 1102 of a photovoltaic support 100 in the third direction F3. The angle between the direction from the starting end to the terminating end of the same supporting portion 1102 and the direction from the first end d1 to the second end d2 of the first support wall b1 connected thereto can be set as a right angle, an acute angle, or an obtuse angle according to the actual angular requirements of the photovoltaic module 200, so as to meet the requirement that the photovoltaic module 200 needs to be installed at a certain angle in order to receive sunlight.

[0063] Reference can continue to be made to Figure 1 、 Figure 2a and Figure 2b, the photovoltaic module 200 is installed on two first support walls b1 of adjacent different photovoltaic brackets 100. Since the distances from the second ends d2 to the first ends d1 of the two first support walls b1 of the adjacent different photovoltaic brackets 100 are different, and the first ends d1 of the two support walls are spaced in the first direction F1, the connection line of the second ends d2 of the two first support walls b1 of the adjacent different photovoltaic brackets 100 is inclined. From Figure 1 and Figure 2a and Figure 2b it can be seen that among the adjacent different photovoltaic brackets 100, the first target part T1 of one of the photovoltaic brackets 100 and the second target part T2 of the other photovoltaic bracket 100 both extend on the above-mentioned inclined connection line, that is, the starting end q1, the terminating end z1 of the first target part T1 of one of the photovoltaic brackets 100, the terminating end z2, and the starting end q2 of the second target part T2 of the other photovoltaic bracket 100 are all on the same inclined connection line.

[0064] Generally, the starting end q1 of the first target part T1 is connected to the second end d2 of the first support wall b1 that is farther from the second support part 1101, and the starting end q2 of the second target part T2 is connected to the second end d2 of the first support wall b1 that is closer to the second support part 1101, so as to facilitate the installation of the photovoltaic module 200 on the supporting part 1102.

[0065] In some embodiments of the present application, the thickness of the bracket body 110 is 5 mm to 6 mm; and / or, the length of the second support wall b2 is 10 mm to 450 mm.

[0066] The weight of the photovoltaic module 200 depends on the materials and design used. Exemplarily, according to relevant usage requirements, the weight per square meter is approximately between 15 kg and 20 kg. Corresponding to this weight range, the thickness of the bracket body 110 can be set to 5 mm to 6 mm. Within this range, the overall strength of the photovoltaic bracket 100 formed by the bracket body 110 is sufficient to support the photovoltaic module 200. Setting the length of the second support wall b2 to 10 mm to 450 mm can effectively disperse the weight of the photovoltaic module 200, reduce the local pressure on the bracket, and improve the stability of the overall structure. The specific parameter selection of the thickness of the bracket body 110 and the length of the second support wall b2 can be actually selected according to the specific weight of the photovoltaic module 200, which is not limited herein.

[0067] In some embodiments of the present application, continue to refer to Figure 1 , and in combination with referring to Figure 4 , Figure 4 For Figure 1The partial enlarged view at position B in the figure. The photovoltaic support 100 further includes a mounting member 120, and the mounting member 120 is used to fix both ends of the photovoltaic module 200 to the corresponding supporting portion 1102.

[0068] To enable the photovoltaic module 200 to be fixedly installed at the desired position, the photovoltaic support 100 further includes a mounting member 120, and the mounting method can be screw connection or snap connection.

[0069] In some embodiments of the present application, continue to refer to Figure 1 and Figure 4 , the supporting portion 1102 has a starting end connecting to the corresponding second end d2 and a terminating end extending in a direction away from the first supporting wall b1 to which the supporting portion 1102 is connected. The mounting member 120 includes two mounting groups, one mounting group is used to mount one end of the photovoltaic module 200, and the other mounting group is used to mount the other end of the photovoltaic module 200. Each mounting group includes a pressing member 121 and a fastening member 122. The pressing member 121 includes a first pressing wall y1, a second pressing wall y2, and a third pressing wall y3. The first pressing wall y1 and the second pressing wall y2 are spaced apart in a direction perpendicular to the direction from the starting end to the terminating end. The third pressing wall y3 connects the first pressing wall y1 and the second pressing wall y2. The first pressing wall y1 is used to abut against the top surface of the photovoltaic module 200 facing away from the second supporting wall b2. The second pressing wall y2 abuts against the surface of the supporting portion 1102 facing away from the second supporting wall b2. The third pressing wall y3 is used to abut against the side wall of the photovoltaic module 200 extending in the direction from the starting end to the terminating end of the supporting portion, and the second pressing wall y2 is connected to the supporting portion 1102 through the fastening member 122.

[0070] The pressing member 121 refers to an element that presses a certain component. The first pressing wall y1 presses the photovoltaic module 200 towards a position closer to the second supporting wall b2. The second pressing wall y2 presses the entire pressing wall onto the supporting portion 1102 by its own gravity. The third pressing wall y3 presses the photovoltaic module 200 in the direction from the starting end to the terminating end of the above-mentioned supporting portion. The fastening member 122 refers to an element such as a thread, a screw, or a snap that connects two components together.

[0071] With such a design, all surfaces of the photovoltaic module 200 are in contact with the supporting portion 1102 or the mounting member 120. When the photovoltaic module 200 shakes, there will be relative sliding between the photovoltaic module 200 and the supporting portion 1102 or the mounting member 120. At this time, frictional force will be generated between the contact surface between the photovoltaic module 200 and the supporting portion 1102 or the contact surface between the photovoltaic module 200 and the mounting member 120, which hinders the shaking of the photovoltaic module 200 and further stably mounts the photovoltaic module 200 onto the supporting portion 1102.

[0072] In addition, continue to refer toFigure 2a , Figure 2b and Figure 4 , taking the example of fixing the photovoltaic module 200 to the first target part T1 through the mounting member 120, the position of the mounting member 120 can be selected at the central position of the first target part T1. If the mounting member 120 is arranged near the termination end z1 of the first target part T1, the pressure exerted by the photovoltaic module 200 on the first target part T1 is at the termination end z1. At this time, the moment is the distance between the termination end z1 and the starting end q1 multiplied by the pressure exerted by the photovoltaic module 200 on the first target part T1, and the moment is the largest, and the starting end q1 is prone to breakage. If the mounting member 120 is arranged near the starting end q1, at this time, the intersection of the starting end and the second support wall b2 bears the weight of the photovoltaic module 200, and after integral molding here, it is in a bent shape and is relatively fragile. When the weight of the photovoltaic module 200 is slightly larger or the photovoltaic module 200 shakes due to wind, the starting end of the first target part T1 is easily broken.

[0073] Based on the same inventive concept, an embodiment of the present application provides a photovoltaic system 10, including the photovoltaic support 100 in any of the above embodiments and a plurality of photovoltaic modules 200. The advantages possessed by the above photovoltaic support 100 are also possessed by the photovoltaic system 10, which will not be elaborated here.

[0074] Please refer to Figure 5 , Figure 5 , which is a schematic top view of the photovoltaic system 10 in some embodiments of the application. All the photovoltaic modules 200 are arranged in rows along the first direction F1 and in columns along the second direction F2. The second direction F2 is perpendicular to the first direction F1, and both the first direction F1 and the second direction F2 are parallel to the roof surface.

[0075] The photovoltaic modules 200 are arranged in an array to maximize the coverage rate of the roof surface and effectively utilize the space of the roof surface. And in the photovoltaic array, the shadow occlusion between the photovoltaic modules 200 will affect the energy output. By arranging them in rows and columns in sequence, the influence of shadow occlusion can be reduced and the overall power generation efficiency can be improved.

[0076] Continuing to refer to Figure 5 , as Figure 5 shown, the first direction F1, the second direction F2 and the third direction F3 are perpendicular to each other. It can be understood that the first direction F1, the second direction F2 and the third direction F3 are only for the convenience of description and do not limit the embodiments of the present application.

[0077] Among them, along the first direction F1, two adjacent photovoltaic modules 200 are connected by means of at least one photovoltaic support 100. The photovoltaic module 200 located at the most upstream along the first direction F1 is defined as the first photovoltaic module 210, and the photovoltaic module 200 located downstream along the first direction F1 is defined as the second photovoltaic module 220; the first photovoltaic module 210 has a first side facing away from the second photovoltaic module 220, and the second photovoltaic module 220 has a second side facing away from the first photovoltaic module 210; the first side of the first photovoltaic module 210 is correspondingly connected to at least one photovoltaic support 100, and the second side of the second photovoltaic module 220 is correspondingly connected to at least one photovoltaic support 100.

[0078] In this way, each end of the photovoltaic module 200 is installed on the supporting part 1102, further improving the installation stability of the photovoltaic module 200.

[0079] In some embodiments of the present application, continue to refer to Figure 5 , along the first direction F1, two adjacent photovoltaic modules 200 are connected by means of two photovoltaic supports 100; and / or, the first side of the first photovoltaic module 210 is correspondingly connected to two photovoltaic supports 100; and / or, the second side of the second photovoltaic module 220 is correspondingly connected to two photovoltaic supports 100.

[0080] Connect two adjacent photovoltaic modules 200 by means of two photovoltaic supports 100, so that each end of the photovoltaic module 200 is installed on the photovoltaic support 100, further improving the installation stability of the photovoltaic module 200. The first side of the first photovoltaic module 210 is correspondingly connected to two photovoltaic supports 100, and the second side of the second photovoltaic module 220 is correspondingly connected to two photovoltaic supports 100. In this way, each end of the photovoltaic module 200 is supported by two photovoltaic supports 100, further improving the installation stability of the photovoltaic module 200 and reducing the risk of shaking of the photovoltaic module 200.

[0081] In some embodiments of the present application, continue to refer to Figure 1 and Figure 5 , in combination with referring to Figure 6 , Figure 6 is Figure 5 a partial enlarged view of the C position in

[0082] With such a design, when installing adjacent photovoltaic modules 200, the contact side length thereof shall be equal to the width of the photovoltaic module 200. The width refers to the shortest side among the inner side lengths of the cross-section with the largest area of the photovoltaic module 200. Moreover, the supporting parts 1102 of the photovoltaic support 200 are also spaced in the width direction of the photovoltaic module 200. Thus, when the photovoltaic modules 200 require the same inclination angle, the minimum distance designed for the two supporting parts 1102 in the third direction F3 is required. When the wind blows from the second direction F2, the wind suction force received is smaller and the anti-overturning ability is stronger.

[0083] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.

[0084] The above embodiments only represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be understood as a limitation to the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
