Description

Technical Field

[0001] This utility model relates to the field of photovoltaic power generation technology, and in particular to an auxiliary structure for photovoltaic modules, a photovoltaic module, and a photovoltaic power generation system. Background Technology

[0002] With the global demand for clean energy constantly rising, the solar photovoltaic industry, as a crucial component of renewable energy, is developing rapidly. To improve the power generation efficiency of solar photovoltaic power plants and reduce electricity costs, photovoltaic tracking brackets have emerged. The angle of sunlight varies with day and night and seasons; traditional fixed brackets, with their fixed angles, cannot track the sun in real time, thus limiting solar energy utilization. Once installed on photovoltaic modules, the photovoltaic tracking brackets can track the sun's position in real time and automatically adjust the angle of the photovoltaic modules, maximizing the amount of solar radiation received by the modules and significantly improving power generation efficiency.

[0003] In related technologies, the load capacity of tracking brackets is mostly around 2000Pa. For some photovoltaic power stations in special environments, such as windy coastal areas, high-altitude windy areas, or areas with high snow loads, the load capacity of photovoltaic modules is difficult to meet the requirements. The glass panels of photovoltaic modules are at high risk of breaking under stress, which shortens the service life of photovoltaic modules. Utility Model Content

[0031] The embodiments of this utility model are described in detail below. The embodiments described with reference to the accompanying drawings are exemplary. Figure 1 This invention describes an auxiliary structure 100 for a photovoltaic module 200 according to an embodiment of the present invention.

[0032] Combination Figure 1 According to the first aspect of the present invention, the auxiliary structure 100 for a photovoltaic module 200 includes a body 1.

[0033] Specifically, combined Figure 1 The main body 1 includes a connecting portion 11 and a clearance portion 12 connected together. The clearance portion 12 protrudes along the thickness direction of the connecting portion 11 toward a side away from the connecting portion 11. The connecting portion 11 is adapted to be connected to the photovoltaic module 200. For example, in Figure 1In the example, the avoidance part 12 is along the height direction of the auxiliary structure 100 (e.g., Figure 1 The auxiliary structure 100 protrudes upwards (in the direction indicated by the middle arrow A). It has a simple structure, is easy to process and shape, is convenient to install and easy to operate, which reduces the production cost of photovoltaic module 200 and improves its production efficiency.

[0034] When the auxiliary structure 100 is used on the photovoltaic module 200, the auxiliary structure 100 is installed on the back of the photovoltaic module 200, the clearance part 12 protrudes towards the tracking axis 300 on the photovoltaic module 200, and the connecting part 11 is connected to the photovoltaic module 200 so that the auxiliary structure 100 can be stably installed on the photovoltaic module 200. With this configuration, when the photovoltaic module 200 experiences high loads due to rain, snow, dust, or other conditions, such as... Figure 4 As shown, this leads to a shortened distance between the tracking axis 300 and the junction box 202. The junction box 202 may come into contact with the tracking axis 300. The rotation of the tracking axis 300 will generate stress on the junction box 202. The auxiliary structure 100 can disperse the stress on the tracking axis 300. For example, without the auxiliary structure 100, the photovoltaic module 200 only has one stress point at the junction box 202. By setting the auxiliary structure 100, the photovoltaic module 200 has at least two stress points: the junction box 202 and the connection part 11. This reduces the possibility of the back glass of the photovoltaic module 200 breaking due to high external loads, improves the load capacity of the photovoltaic module 200, and extends the service life of the photovoltaic module 200. In addition, the avoidance part 12 can be used to avoid the junction box 202 or other components on the photovoltaic module 200, so as to protect the junction box 202 or other components and reduce the probability of damage to the junction box 202 or other components after being subjected to the force of the tracking axis 300, thereby making it more conducive to the long-term stable use of the auxiliary structure 100 and the photovoltaic module 200.

[0035] According to the embodiment of this utility model, the auxiliary structure 100 for photovoltaic module 200 has a simple structure, is easy to process and form, convenient to install, and easy to operate, thereby reducing the production cost of photovoltaic module 200 and improving the production efficiency of photovoltaic module 200. When the auxiliary structure 100 is used for photovoltaic module 200, it can disperse the stress on the tracking shaft 300, changing the stress point on photovoltaic module 200 from one stress point at junction box 202 to at least two points at junction box 202 and connection part 11, thereby reducing the possibility of breakage of the back glass of photovoltaic module 200 due to high external load, improving the load capacity of photovoltaic module 200, and extending the service life of photovoltaic module 200.

[0036] According to some embodiments of this utility model, combined with Figures 1-4The clearance portion 12 has flanges 121 on both sides in the width direction (e.g., the direction perpendicular to the plane in the figure), and the free end 1211 of the flange 121 extends along the thickness direction of the connecting portion 11 toward the side where the connecting portion 11 is located.

[0037] For example, in Figure 1 In the example, the upper side of the flange 121 is connected to the bottom wall of the clearance portion 12, and the lower side of the flange 121 extends downward. The flange 121 is located on the front and rear sides of the clearance portion 12, which can be understood as adding two reinforcing structures at the front and rear edges of the clearance portion 12. This allows the auxiliary structure 100 to better resist deformation when subjected to external forces, such as the pressure of rain, snow, sand, or other outdoor debris on the tracking axis 300, thereby making the overall structure of the auxiliary structure 100 stronger and more stable. Furthermore... After the photovoltaic module 200 is deformed by external force, the relief part 12 comes into contact with the tracking axis 300. That is, the relief part 12 is the area with the most concentrated stress in the auxiliary structure 100. The flanges 121 on the front and rear sides of the relief part 12 can disperse the concentrated stress to a larger area, thereby reducing the stress level in the local area of ​​the relief part 12. This allows the auxiliary structure 100 to better disperse the pressure on the back glass of the photovoltaic body 201, preventing the back glass from breaking due to excessive stress and extending the service life of the photovoltaic module 200.

[0038] For example, the auxiliary structure 100 can be an integral steel structure. Steel has high strength and rigidity, and the auxiliary structure 100 is made of steel so that it can withstand various external forces, such as gravity, wind load, and seismic forces, that the photovoltaic module 200 experiences during installation and use. The steel structure contributes to the stability and safety of the photovoltaic module 200, preventing the backsheet glass of the photovoltaic body 201 from breaking due to insufficient strength of the auxiliary structure 100. Furthermore, steel is easy to process and form, the production process is mature, and the processing precision is high, ensuring a good fit between the auxiliary structure 100 and the photovoltaic module 200, reducing the production cost of the auxiliary structure 100, and improving the overall production efficiency of the photovoltaic module 200.

[0039] Optionally, in Figure 1 In the example, the left and right sides of the flange 121 are connected to the corresponding connecting parts 11 on both sides to form an integral structural component. This further strengthens the structural strength of the auxiliary structure 100 and prevents the sub-connecting parts 111 from falling off during installation or use, thus affecting the installation and use of the auxiliary structure 100.

[0040] According to some embodiments of this utility model, the side of the flange 121 near the connecting portion 11 is flush with the other side of the connecting portion 11. For example, the free end 1211 of the flange 121 is flush with the upper side of the connecting portion 11 (not shown in the figure). Thus, the flange 121 extends in the height direction to be flush with the connecting portion 11, increasing the height of the flange 121 in the height direction. This further strengthens the structural strength of the avoidance portion 12, thereby further strengthening the structural strength of the auxiliary structure 100 and improving the connection performance of the auxiliary structure 100. Furthermore, the increased height of the flange 121 can be understood as increasing the thickness and support area at the edge of the auxiliary structure 100, enabling the auxiliary structure 100 to better resist deformation, thereby ensuring the stability and reliability of the entire structure and improving its performance.

[0041] According to some embodiments of this utility model, combined with Figure 3 and Figure 4 The distance between the two flanges 121 is suitable to be greater than the width of the junction box 202 of the photovoltaic module 200.

[0042] For example, the junction box 202 is an electrical component that enables electrical connections between the cells inside the photovoltaic module 200 and between the photovoltaic module 200 and external circuits. When the photovoltaic module 200 is installed outdoors, with proper protective measures, the junction box 202 can be protected from water ingress and short circuits, or from debris blocking the passage due to rain, snow, or sandstorms. When the distance between the two flanges 121 is less than the width of the junction box 202, interference may occur between the junction box 202 and the flanges 121, which is detrimental to the installation of the junction box 202 and the auxiliary structure 100. When the distance between the two flanges 121 is greater than the width of the junction box 202, the auxiliary structure 100 can enclose the junction box 202 within it, providing further protection and insulation for the electrical wiring inside the junction box 202, thereby ensuring the connectivity between the junction box 202 and the photovoltaic module 200. It should be noted that the distance between the two flanges 121 needs to be set according to the actual situation; no specific limit is imposed here.

[0043] According to some embodiments of this utility model, combined with Figures 2-4 The connecting portion 11 includes two sub-connecting portions 111, which are respectively connected to the length direction of the avoidance portion 12 (e.g., Figure 1 The two ends (in the direction indicated by the middle arrow B) are connected.

[0044] For example, combining Figure 3Two sub-connecting parts 111 are located on the left and right sides of the auxiliary structure 100. The auxiliary structure 100 is bonded (e.g., with silicone) to the photovoltaic body 201 through the two sub-connecting parts 111, thereby forming a stable connection with the photovoltaic module 200. The presence of the two sub-connecting parts 111 makes the connection between the auxiliary structure 100 and the photovoltaic module 200 more stable, better able to withstand various external forces, and reduces the risk of deformation, loosening, or even detachment caused by uneven force on one side of the connection. Moreover, this highly symmetrical structure on both sides can reduce the production and installation difficulty of the auxiliary structure 100 while ensuring its effective function, reduce problems such as vibration and displacement caused by uneven force, and improve the performance of the photovoltaic module 200. Furthermore, when the external pressure on the photovoltaic module 200 is high, the auxiliary structure 100 can also evenly distribute the stress to the sub-connection parts 111 on the left and right sides. The stress points on the back of the photovoltaic module 200 increase from one point in the junction box 202 to three points in the avoidance part 12 and the two sub-connection parts 111. The stress on the back glass of the photovoltaic body 201 is more even, further improving the load-bearing capacity of the auxiliary structure 100.

[0045] It should be noted that the number of sub-connection parts 111 can be set according to the actual situation, such as the volume of the photovoltaic body 201 and the installation environment. For example, two sub-connection parts 111 can be added at the flange 121 position to make the auxiliary structure 100 more stably installed on the large photovoltaic module 200.

[0046] According to some optional embodiments of this utility model, the two sub-connecting parts 111 are respectively adapted to be bonded to the photovoltaic body 201 of the photovoltaic module 200. For example, the sub-connecting parts 111 are fixed to the photovoltaic module 200 by silicone adhesive. The silicone adhesive has high bonding strength, which enables the auxiliary structure 100 to be firmly bonded to the photovoltaic module 200. When the photovoltaic module 200 is installed in an outdoor environment that is exposed for a long time, the bonding area is not prone to aging, effectively improving the application performance of the auxiliary structure 100 in harsh environments and ensuring its performance and service life.

[0047] According to some embodiments of this utility model, combined with Figure 1 The auxiliary structure 100 is a bent or stamped part.

[0048] For example, bent parts are produced by bending raw materials such as metal sheets, pipes, or profiles into workpieces with specific curvature, shape, and dimensions. Therefore, the auxiliary structure 100, as a bent part, can be processed into workpieces of various shapes and angles according to actual installation requirements. During the bending process, the material shape is mainly changed through plastic deformation, effectively reducing material waste, improving material utilization, and lowering the production cost of the auxiliary structure 100. Furthermore, the internal structure of the material changes during bending, increasing its strength and hardness to a certain extent, enhancing the load-bearing capacity and deformation resistance of the auxiliary structure 100, and improving the performance and lifespan of the photovoltaic module 200. In addition, the bending process is complete, resulting in high dimensional accuracy, good shape consistency, and high production efficiency, effectively reducing the production cost of the auxiliary structure 100 and facilitating its large-scale production and application.

[0049] Stamping is a process of forming metal or non-metal sheets into parts with specific shapes and dimensions using stamping. During stamping, the internal structure of the material changes; while the metal sheet undergoes plastic deformation, its strength and hardness increase, giving the stamped part high strength and rigidity. This allows it to withstand greater external forces and loads, ensuring the load-bearing capacity of the auxiliary structure 100 and improving the performance of the photovoltaic module 200. Furthermore, stamping offers high production efficiency and material utilization, effectively reducing the production cost of the auxiliary structure 100.

[0050] Therefore, when the auxiliary structure 100 is a bent or stamped part, it can be processed into components of various shapes and angles according to actual conditions, making the auxiliary structure 100 suitable for installation in various application scenarios and increasing its application range. Bending or stamping can improve the strength and hardness of the material, giving the auxiliary structure 100 a stronger load-bearing capacity, thereby improving the performance and lifespan of the photovoltaic module 200. Furthermore, bending and stamping processes are complete and have high production efficiency, effectively reducing the production cost of the auxiliary structure 100 and facilitating its large-scale production and application.

[0051] According to some embodiments of this utility model, combined with Figure 1 The side of the connecting portion 11 away from the avoidance portion 12 is formed as a plane. And / or, the side of the avoidance portion 12 away from the connecting portion 11 is formed as a plane.

[0052] For example, combining Figure 1The lower side of the connecting part 11 has a planar connection surface with the photovoltaic body 201, resulting in a larger contact area between the connecting part 11 and the photovoltaic body 201. This effectively improves the bonding strength and stability of the auxiliary structure 100, thereby reducing the risk of the auxiliary structure 100 detaching. Furthermore, the planar structure of the lower side of the connecting part 11 simplifies the bonding of the auxiliary structure 100 to the photovoltaic module 200, improving the production efficiency of the photovoltaic module 200. It also reduces the processing difficulty of the auxiliary structure 100, further increasing production efficiency.

[0053] exist Figure 1 In the example, the area on the upper side of the clearance portion 12 that contacts the tracking axis 300 of the photovoltaic module 200 is a planar structure. This planar structure provides a larger contact area between the clearance portion 12 and the tracking axis 300, better dispersing the stress generated by the movement of the tracking axis 300. This further reduces the likelihood of the backsheet glass breaking due to excessive external load, thereby extending the service life of the photovoltaic module 200. Furthermore, the planar structure reduces the relative movement between the auxiliary structure 100 and the tracking axis 300, reducing wear and extending its service life. In addition, the planar structure is simple to manufacture, has low production costs, and is easy to install, making the auxiliary structure 100 suitable for large-scale production applications.

[0054] It should be noted that, as Figure 1 The shapes of the lower surface of the connecting portion 11 and the upper surface of the clearance portion 12 can be specifically designed according to actual use to better meet practical applications. Furthermore, the lower surface of the connecting portion 11 and the upper surface of the clearance portion 12 can both be set as planes, or one of the connecting portion 11 and the clearance portion 12 can be set as a plane, as long as it meets practical needs. In addition, the flange 121 has a simple structure and is easy to process, effectively improving its structural strength and load-bearing capacity without affecting the production cost and efficiency of the auxiliary structure 100.

[0055] According to the photovoltaic module 200 of the second aspect embodiment of the present utility model, combined with Figures 2-4 This includes an auxiliary structure 100 for a photovoltaic module 200 according to the first aspect embodiment described above.

[0056] According to the embodiments of the present invention, the photovoltaic module 200, by employing the aforementioned auxiliary structure 100, significantly improves the load-bearing capacity of the photovoltaic module 200, enhances its performance, and extends its service life. For example, the photovoltaic module 200 can be used in solar power plants, electric vehicles, solar traffic lights, etc.

[0057] According to some embodiments of this utility model, combined with Figures 2-5The photovoltaic module 200 also includes a photovoltaic body 201 and a junction box 202. Specifically, the auxiliary structure 100 is located on the back of the photovoltaic body 201. The junction box 202 is located between the photovoltaic body 201 and the clearance portion 12 of the auxiliary structure 100, with the center of the junction box 202 opposite to the center of the auxiliary structure 100.

[0058] Specifically, the photovoltaic body 201 typically includes components such as solar cells, backsheet glass, backsheet, and frame (not shown in the figure). For example, combined with Figure 4 Three junction boxes 202 are installed on the back glass of the photovoltaic module 201, located at the left and right ends and the center of the photovoltaic module 201, respectively. The junction boxes 202 provide a centralized location for the electrical connection between the photovoltaic module 201 and the tracking axis 300, ensuring stable and safe current transmission. They also collect and integrate the DC power generated by the photovoltaic module 200 before transmitting it to other equipment such as the inverter. The junction boxes 202 on the photovoltaic module 200 collect and transmit the current generated by the cells, reducing the transmission distance and resistance loss within the photovoltaic module 200, optimizing current transmission efficiency, and thus improving the overall power generation efficiency of the photovoltaic module 200.

[0059] It should be noted that the number and installation position of the junction boxes 202 can be set according to factors such as the size and power of the photovoltaic module 200 and the number of solar cells, and are not specifically limited here. Furthermore, the junction boxes 202 are not limited to being opposite the clearance portion 12; the auxiliary structure 100 can also be located on the back of the photovoltaic module 200 at other positions besides where the junction boxes 202 are located, to similarly distribute the stress on the tracking axis 300. Preferably, the clearance portion 12 and the junction boxes 202 are opposite each other along the height direction of the auxiliary structure 100.

[0060] For example, combining Figure 5 When the auxiliary structure 100 is not provided in the photovoltaic module 200, and the tracking shaft 300 exerts external pressure on the junction box 202 and generates stress on the photovoltaic body 201, the stress point on the back of the photovoltaic body 201 is only one point: the junction box 202. When the stress on the back of the photovoltaic module 200 increases to a certain level, the back glass of the photovoltaic body 201 may break, thereby affecting the service life of the photovoltaic module 200. In this application, combined with Figure 4The auxiliary structure 100 is located on the back of the photovoltaic module 201, and its center is opposite to the center of the junction box 202 located at the center of the photovoltaic module 201. When the photovoltaic module 201 deforms due to external pressure, the clearance part 12 of the auxiliary structure 100 contacts the tracking axis 300, and the wire of the junction box 202 will also contact the clearance part 12 of the auxiliary structure 100. At this time, the junction box 202 is subjected to force and generates a certain stress on the photovoltaic module 201. By adding the auxiliary structure 100 and aligning its center with the junction box 202 located at the center of the photovoltaic module 201, the number of stress points on the back of the photovoltaic module 200 increases from one point on the junction box 202 to three points. At this time, the stress on the back glass of the photovoltaic module 201 is more uniform, effectively improving the load-bearing capacity of the photovoltaic module 200, reducing the risk of breakage of the back glass of the photovoltaic module 201, and increasing the application scenarios of the photovoltaic module 200. For example, in relatively remote areas with high snow loads and high wind loads. Furthermore, the center of the junction box 202 is opposite to the center of the auxiliary structure 100. This arrangement allows the photovoltaic module 200 to be evenly transmitted to the junction box 202 and the entire photovoltaic module 200 structure through the tracking shaft 300 when subjected to external forces such as wind or gravity. This avoids excessive local stress due to uneven force distribution, reduces the risk of deformation and damage to the photovoltaic body 201, and improves the stability and reliability of the photovoltaic module 200.

[0061] According to some embodiments of this utility model, combined with Figures 2-4 There is a gap 210 between the junction box 202 and the clearance part 12.

[0062] When the photovoltaic module 200 is subjected to pressure on its front side, it will deform to a certain extent. If there is no gap 210 between the buffer section 12 and the junction box 202, the upper end of the junction box 202 may directly contact the lower end of the buffer section 12, causing the backsheet glass of the photovoltaic body 201 to be subjected to upward force by the junction box 202, thereby increasing the risk of backsheet glass breakage. The gap 210 reserved between the junction box 202 and the auxiliary junction buffer section 12 provides a buffer space for the deformation of the photovoltaic module 200, preventing backsheet glass breakage, protecting the integrity of the photovoltaic module 200, and reducing module failure and repair costs caused by backsheet glass breakage. Furthermore, the existence of the gap 210 ensures that when the photovoltaic module 200 is subjected to a small external force, the junction box 202 does not contact the bottom wall of the buffer section 12, allowing the junction box 202 some room to move and better adapt to various load conditions. When the photovoltaic module 200 is subjected to a large load, the photovoltaic body 201 deforms, which in turn causes the relief portion 12 of the auxiliary structure 100 to deform. At this time, the relief portion 12 can deform slightly in the direction of the gap 210, instead of directly transmitting the force to the junction box 202 and the tracking shaft 300. This improves the overall load-bearing capacity of the photovoltaic module 200, enabling it to withstand greater external forces such as wind and snow loads, thus enhancing the stability and reliability of the photovoltaic module 200. It should be noted that the size of the aforementioned gap 210 can be specifically set according to actual usage conditions to better meet practical applications.
