[0030] With increasing awareness of renewable energy utilization, photovoltaic (PV) power generation, as one of the main methods of solar energy utilization, has been widely applied. In related technologies, photovoltaic (PV) components can be installed on rooftops or other carriers to convert solar energy into electrical energy, achieving energy conservation and environmental protection. Generally, PV systems, such as PV houses, include PV modules, which in turn include PV components. These PV components can be directly laid on the surface of the carrier, meaning they are in close contact with the carrier surface. This results in poor heat dissipation for the PV components, easily affecting their photoelectric conversion efficiency. Please refer to [link to relevant documentation]. Figure 1 To address the aforementioned problems, this application provides a photovoltaic system 100.

[0031] Please see Figure 1 The photovoltaic system 100 of this application includes a support component 10 and a photovoltaic module 30. It should be noted that, in some embodiments, the photovoltaic system 100 includes photovoltaic houses, photovoltaic carports, ground-mounted power stations, and floating photovoltaic systems, etc.

[0032] It is understood that the support component 10 is a structure in the photovoltaic system 100 used to fix, support, and adjust the photovoltaic module 30, ensuring that the photovoltaic module 30 can receive light at an optimal angle and position, while also resisting the effects of environmental factors (such as wind, rain, snow, etc.). In some embodiments, the photovoltaic system 100 also includes a carrier, including but not limited to a roof, column, etc., on which the photovoltaic module 30 can be mounted via the support component 10. For example, the support device may include structural components such as purlins to provide a stable support platform for the photovoltaic module 30, enabling the photovoltaic module 30 to be mounted on a carrier such as a roof.

[0033] Photovoltaic modules 30 are a collection of components in photovoltaic system 100 used to convert solar energy into electrical energy. These modules enable sustainable energy use. The photovoltaic modules 30 do not produce greenhouse gases or pollutants such as carbon dioxide during power generation, resulting in a low environmental impact. They help reduce dependence on traditional energy sources and mitigate air pollution and climate change. The photovoltaic modules 30 can be distributed and installed in various locations, such as rooftops, ground surfaces, and water surfaces, using support components 10 to fully utilize solar energy resources. This distributed layout helps reduce transmission losses and improves the stability and resilience of the power system. The photovoltaic modules 30 can be combined and expanded as needed, suitable for power generation systems of various sizes and requirements. In some embodiments of this application, the photovoltaic system 100 includes a photovoltaic roof, in which case the photovoltaic modules 30 can be installed on the roof using support components 10 to collectively form a photovoltaic roof.

[0034] In some embodiments, the photovoltaic module 30 may be installed on the support component 10 using a detachable connection method, which facilitates the removal of the photovoltaic module 30 from the support component 10 when maintenance or replacement is required. The detachable connection method includes, but is not limited to, bolt connections and snap-fit ​​connections. In other embodiments, the photovoltaic module 30 may be installed on the support component 10 using a non-detachable connection method, which improves the connection strength between the photovoltaic module 30 and the support component 10, enhances the photovoltaic system 100's ability to withstand external environmental factors, and ensures the stability and reliability of the photovoltaic system 100's operation. The non-detachable connection method includes, but is not limited to, bonding or welding.

[0035] Furthermore, in some embodiments, the photovoltaic system 100 also includes an energy storage component electrically connected to the photovoltaic module 30. The energy storage component can store the electrical energy generated by the photovoltaic module 30 and supply power to loads such as household appliances and portable devices. The energy storage component and the photovoltaic module 30 can be electrically connected via cables or through intermediate devices such as junction boxes 35 or busbars. It should be noted that in some embodiments, the energy storage component can be a lithium-ion battery, a lead-acid battery, or other types of rechargeable batteries, or it can be a supercapacitor or other device capable of storing and releasing electrical energy.

[0036] The photovoltaic system 100 will be further explained below with reference to the accompanying drawings.

[0037] Please see Figure 1 In some embodiments, the support assembly 10 is disposed on the carrier and includes a plurality of spaced-apart first support members 11 and a plurality of spaced-apart second support members 13, with the first support members 11 and the second support members 13 being arranged crosswise. The photovoltaic module 30 includes a plurality of photovoltaic elements 31, which are connected to the first support members 11 and / or the second support members 13. The plurality of photovoltaic elements 31 and the support assembly 10 together form a plurality of heat dissipation spaces 101, which are in communication with the outside air.

[0038] It is understood that the first support member 11 is a structural component used to support the photovoltaic module 30. The first support member 11 can be generally a long, narrow columnar structure, and its cross-sectional shape can include, but is not limited to, square, circular, and triangular shapes. The first support member 11 can be made of metallic and / or non-metallic materials. Metallic materials include, but are not limited to, aluminum, iron, steel, or aluminum alloys, while non-metallic materials include, but are not limited to, plastics. For example, the first support member 11 can be made of metallic materials, such as aluminum alloy. This improves the structural strength of the first support member 11, enhances its ability to withstand external environmental conditions, and ensures the stability and reliability of the photovoltaic system 100.

[0039] The structure of the second support member 13 is largely the same as that of the first support member 11. For details, please refer to the explanation of the first support member 11, which will not be repeated here. It should be noted that the materials of the first support member 11 and the second support member 13 can be the same or different, and this application does not impose any restrictions.

[0040] The first support member 11 and the second support member 13 are arranged in a cross manner, that is, the first support member 11 and the second support member 13 are connected in a cross manner. On the one hand, this can distribute the load on the support component 10, improve the support component 10's ability to resist external environmental factors, and ensure the stability and reliability of the photovoltaic system 100. On the other hand, it can make the multiple first support members 11 and multiple second support members 13 have a gap space, thereby ensuring the formation of the heat dissipation space 101.

[0041] In some embodiments of this application, a plurality of first support members 11 are arranged at intervals along a first direction X, and a plurality of second support members 13 are arranged at intervals along a second direction Y, wherein the first direction X and the second direction Y are perpendicular. This improves the ability of the support assembly 10 to resist external environmental factors, ensuring the stability and reliability of the photovoltaic system 100; it also makes the arrangement of the first support members 11 and the second support members 13 more orderly, improving aesthetics. It should be noted that in some embodiments, the length direction of the first support member 11 is perpendicular to the first direction X, and the length direction of the second support member 13 is perpendicular to the second direction Y.

[0042] In some embodiments, a vibration damping element is provided at the intersection of the first support member 11 and the second support member 13. The vibration damping element is used to absorb vibration energy, reduce the possibility of damage to the first support member 11 or the second support member 13, and improve the stability of the photovoltaic system 100. It should be noted that in some embodiments, the material of the vibration damping element includes, but is not limited to, rubber, silicone, etc.

[0043] The photovoltaic element 31 can be different types of solar energy conversion devices, such as monocrystalline silicon, polycrystalline silicon, or thin-film solar cells. Users can select photovoltaic elements 31 with different efficiencies and sizes according to their usage needs and environmental conditions. Multiple photovoltaic elements 31 can have the same shape and different sizes. For example, to accommodate the size of the carrier, users can select at least two different sizes of photovoltaic elements 31. In some embodiments, the shape of the photovoltaic element 31 can include a planar structure or a curved structure to adapt to different user needs, achieving better utilization of solar energy and improving the photoelectric conversion efficiency of the photovoltaic module 30. In some embodiments of this application, the photovoltaic element 31 has a planar structure, and the cross-sectional shape of the photovoltaic element 31 can be square.

[0044] For example, multiple photovoltaic elements 31 can form a fully sealed structure, which improves waterproofing and prevents fluid leakage through the gaps between the photovoltaic elements 31, thus affecting the user experience. A seal is provided between adjacent photovoltaic elements 31 to seal the gaps between them.

[0045] In some embodiments, the photovoltaic element 31 can be laid on the surface of the support component 10, that is, the photovoltaic element 31 is directly disposed on the top of the support component 10 (the uppermost part of the support component 10 in the direction of gravity), which facilitates the assembly of the photovoltaic element 30 and the support component 10 and improves assembly efficiency. In other embodiments, the photovoltaic element 31 can be disposed between two adjacent first support members 11, and / or between two adjacent second support members 13, that is, at least a portion of the photovoltaic element 31 is embedded in the support component 10. Please refer to [the relevant documentation / reference]. Figure 3 The light-receiving surface 301 of the photovoltaic component 31 (the surface of the photovoltaic component 31 that directly faces the sun, receives sunlight, and completes photoelectric conversion) can be flush with the surface of the supporting component 10.

[0046] Furthermore, in some embodiments, the first support member 11 and the second support member 13 are stacked.

[0047] Specifically, in some embodiments, the first support member 11 is connected to the top of the second support member 13 in the direction of gravity. In this case, the photovoltaic element 31 can be connected to the first support member 11. For example, the photovoltaic element 31 can be laid on the surface of the first support member 11 and together with the corresponding first support member 11 and second support member 13, form a heat dissipation space 101. In other embodiments, the second support member 13 is connected to the top of the first support member 11 in the direction of gravity. In this case, the photovoltaic element 31 can be connected to the second support member 13. For example, the photovoltaic element 31 can be laid on the surface of the second support member 13 and together with the corresponding first support member 11 and second support member 13, form a heat dissipation space 101.

[0048] In other embodiments, the surface of the first support member 11 facing the photovoltaic element 31 is flush with the surface of the second support member 13 facing the photovoltaic element 31. That is, in the direction of gravity, the top of the first support member 11 and the top of the second support member 13 are located in the same horizontal plane. In this case, the photovoltaic element 31 can be connected to the first support member 11 and the second support member 13. For example, the photovoltaic element 31 can be laid on the surface of the first support member 11 and the second support member 13; or, at least a portion of the photovoltaic element 31 can be embedded in the space formed by two adjacent first support members 11 and two adjacent second support members 13.

[0049] For example, the first support member 11 is provided with a mounting groove, and the second support member 13 is cross-connected to the first support member 11 through the mounting groove. When the second support member 13 is positioned in the mounting groove, the surface of the first support member 11 facing the photovoltaic element 31 is flush with the surface of the second support member 13 facing the photovoltaic element 31. Alternatively, the second support member 13 is provided with a mounting groove, and the first support member 11 is cross-connected to the second support member 13 through the mounting groove. When the first support member 11 is positioned in the mounting groove, the surface of the first support member 11 facing the photovoltaic element 31 is flush with the surface of the second support member 13 facing the photovoltaic element 31. The mounting groove facilitates the positioning and installation of the first support member 11 or the second support member 13, thereby improving the assembly efficiency of the support assembly 10.

[0050] For ease of understanding, the following embodiments will be described using the example that the surface of the first support member 11 facing the photovoltaic element 31 is flush with the surface of the second support member 13 facing the photovoltaic element 31.

[0051] In the photovoltaic system 100 of this application embodiment, the photovoltaic element 31 is connected to the first support member 11 and / or the second support member 13. Multiple photovoltaic elements 31 and the support assembly 10 together form multiple heat dissipation spaces 101, and the heat dissipation spaces 101 are connected to the outside air. Therefore, compared with the photovoltaic element 31 being directly laid on the carrier, the setting of the heat dissipation space 101 can increase air flow, improve heat dissipation effect, reduce the operating temperature of the photovoltaic element 31, and ensure the photoelectric conversion efficiency of the photovoltaic element 31.

[0052] In addition, in the embodiments of this application, the photovoltaic element 31 and the support component 10 can be used together to form a heat dissipation space 101 to achieve heat dissipation of the photovoltaic element 31. Therefore, compared with the photovoltaic element 31 being directly laid on the carrier and heat dissipation components are used to dissipate heat from the photovoltaic element 31, the structure of the photovoltaic system 100 in this application is simpler. There is no need to set heat dissipation components for the photovoltaic element 31, which can reduce the number of structural components in the photovoltaic system 100 while reducing production costs, which is beneficial to improving the assembly efficiency of the photovoltaic system 100.

[0053] Please continue reading. Figure 1 In some embodiments, multiple heat dissipation spaces 101 are interconnected in the first direction X; and / or, multiple heat dissipation spaces 101 are interconnected in the second direction Y, which can facilitate air flow, improve heat dissipation, further reduce the possibility of overheating of photovoltaic element 31, and improve the photoelectric conversion efficiency of photovoltaic element 31.

[0054] Specifically, in some embodiments, the first support member 11 has a through hole, so that two adjacent heat dissipation spaces 101 can be connected in the first direction X, thereby facilitating air flow between the multiple heat dissipation spaces 101 along the first direction X. In other embodiments, the second support member 13 has a through hole, so that two adjacent heat dissipation spaces 101 can be connected in the second direction Y, thereby facilitating air flow between the multiple heat dissipation spaces 101 along the second direction Y. In still other embodiments, both the first support member 11 and the second support member 13 have through holes, so that the multiple heat dissipation spaces 101 can be connected to each other in the first direction X and the second direction Y, thereby allowing air to flow in multiple directions and improving the heat dissipation effect.

[0055] In some embodiments, a heat dissipation component is provided within the heat dissipation space 101. This heat dissipation component is a device capable of conducting, convection, or radiation heat from the heat source to the surrounding environment. Specifically, the heat dissipation component is used to conduct heat from the photovoltaic element 31 into the heat dissipation space 101 via thermal conduction and to remove heat using airflow, thereby achieving heat dissipation from the photovoltaic element 31, preventing heat buildup, and ensuring that the photovoltaic element 31 does not reduce its photoelectric conversion efficiency due to overheating. It should be noted that in some embodiments, the material of the heat dissipation component includes, but is not limited to, copper, aluminum, thermal grease, and thermal silicone.

[0056] In some embodiments, each photovoltaic element 31, together with the first support 11 and the second support 13, forms at least one heat dissipation space 101.

[0057] Specifically, in some embodiments, each photovoltaic element 31, together with two adjacent first support members 11 and two adjacent second support members 13, forms a heat dissipation space 101, which facilitates the installation and positioning of the photovoltaic element 31 and improves installation efficiency. In other embodiments, each photovoltaic element 31, together with at least two consecutive first support members 11 and at least two consecutive second support members 13, forms at least one heat dissipation space 101. Therefore, compared to each photovoltaic element 31 forming a heat dissipation space 101 together with the support assembly 10, the photovoltaic element 31 is larger in size, resulting in fewer photovoltaic elements 31 and simplifying the assembly steps of the photovoltaic system 100.

[0058] Please see Figure 1 and Figure 2 In some embodiments, the photovoltaic module 30 further includes a connector 33, through which the photovoltaic module 31 is connected to the support assembly 10. It should be noted that in some embodiments, the connector 33 may be at least one of bolts, clips, clamps, adhesives, hinges, and guide rails.

[0059] Furthermore, in some embodiments, the connector 33 includes a plurality of connectors 33, which are respectively disposed at the corners of the photovoltaic element 31.

[0060] Specifically, in some embodiments, the connector 33 may include a first sub-component and a second sub-component. The first sub-component is disposed at the corner of the photovoltaic element 31, and the second sub-component is used to connect the first sub-component to the support assembly 10 to achieve the connection between the photovoltaic element 31 and the support assembly 10. The second sub-component may be a bolt, etc. Multiple connectors 33 are respectively disposed at the corners (e.g., the four corners) of the photovoltaic element 31. This allows the load (such as wind pressure or snow load) on the photovoltaic element 31 to be distributed to multiple support points, avoiding stress concentration on one side, reducing the possibility of torsional deformation of the photovoltaic element 31, and improving the stability and reliability of the photovoltaic module 30.

[0061] Furthermore, in some embodiments, the structural strength of the connector 33 is greater than that of the photovoltaic element 31. Since stress can be transmitted to the support assembly 10 through the connector 33 when the photovoltaic element 31 is subjected to a strong external load, the greater structural strength of the connector 33 reduces the possibility of damage to the connector 33 during stress transmission, prevents damage to the photovoltaic element 31, and improves the stability and reliability of the photovoltaic module 30.

[0062] In some embodiments, the photovoltaic module 30 further includes a blocking member disposed between the photovoltaic module 31 and the support component 10. The blocking member is used to seal the gap between the photovoltaic module 31 and the support component 10. This improves the waterproofing effect and prevents fluid leakage through the gap between the photovoltaic module 31 and the support component 10, thus preventing it from affecting the user experience.

[0063] Specifically, please combine Figure 3 In some embodiments, a blocking member may be disposed between the backlight surface 303 of the photovoltaic element 31 (the surface of the photovoltaic element 31 opposite to the light-receiving surface 301, i.e., the backlight surface 303 is the surface of the photovoltaic element 31 opposite to the sun) and the first support member 11, and between the backlight surface 303 of the photovoltaic element 31 and the second support member 13. The material of the blocking member includes, but is not limited to, rubber, silicone, and adhesive. Wherein, when the material of the blocking member is adhesive, the blocking member can not only be used to seal the gap between the photovoltaic element 31 and the support component 10, but also serve to connect the support component 10 of the photovoltaic element 31, thereby improving the stability of the connection between the photovoltaic element 31 and the support component 10.

[0064] Please see Figure 2 and Figure 3In some embodiments, the photovoltaic element 31 has a battery layer 311. Further, in some embodiments, the photovoltaic element 31 also includes a first cover plate 317 and a second cover plate 319, which are stacked sequentially in the direction from the light-receiving surface 301 to the backlight surface 303, with the battery layer 311 connected between the first cover plate 317 and the second cover plate 319.

[0065] The first cover plate 317 and the second cover plate 319 together protect the battery layer 311 and other internal components of the photovoltaic element 31 from external physical impacts and environmental corrosion, reducing the possibility of damage to the photovoltaic element 31. The battery layer 311, the first cover plate 317, and the second cover plate 319 can be connected together by an adhesive film to form a stable and robust structure, improving the overall structural stability. It should be noted that in some embodiments, the first cover plate 317 and the second cover plate 319 can be made of at least one of the following materials: glass, PET, metal, composite fiber, etc.; the adhesive film can be made of at least one of the following materials: EVA, POE, PVB, etc.

[0066] Please combine Figure 1 In some embodiments, the photovoltaic component 31 includes a connection area 313 and a loading area 315, wherein the connection area 313 is used to connect to the support component 10.

[0067] Specifically, in some embodiments, the connection area 313 includes the corner of the photovoltaic element 31. In this case, the connector 33 can be disposed in the connection area 313, so that the connection area 313 can be connected to the support component 10 through the connector 33 to realize the connection between the photovoltaic element 31 and the support component 10.

[0068] In other embodiments, the connection area 313 surrounds the loading area 315. That is, in addition to including the corners of the photovoltaic element 31, the connection area 313 also includes the area between two adjacent corners of the photovoltaic element 31. This can increase the connection area between the photovoltaic element 31 and the support component 10, improve the bonding strength between the photovoltaic element 31 and the support component 10, enhance the ability of the photovoltaic system 100 to resist the external environment, and ensure the stability of the operation of the photovoltaic system 100.

[0069] In some embodiments, the battery layer 311 is disposed in the loading area 315. Thus, when the connection area 313 is connected to the support assembly 10 by bolts or other connectors 33, the battery layer 311 will not interfere with the connectors 33, thereby ensuring the normal installation of the photovoltaic element 31 on the support assembly 10.

[0070] In other embodiments, the battery layer 311 is disposed in the loading area 315 and the connection area 313. This increases the size of the battery layer 311, allowing the photovoltaic element 31 to capture more sunlight and convert it into electrical energy, thereby improving the power generation efficiency of the photovoltaic element 31. It should be noted that, in this embodiment, the connector 33 can be disposed on the back surface 303 of the photovoltaic element 31, so that the connection area 313 is connected to the support component 10 through the connector 33. Exemplarily, the connector 33 includes, but is not limited to, snap-fit ​​and adhesive.

[0071] Please see Figure 1 and Figure 3 In some embodiments, the photovoltaic module 30 also includes a junction box 35, which is disposed within the heat dissipation space 101 and electrically connected to the photovoltaic module 31.

[0072] Understandably, the junction box 35 is a component in the photovoltaic module 30 used for electrical connection. The junction box 35 can be electrically connected to the photovoltaic element 31 and the energy storage module to form a complete electrical circuit, enabling the electrical energy generated by the photovoltaic element 31 to be transferred to the energy storage module. The heat dissipation space 101 provides protection for the junction box 35, reducing the possibility of liquids or dust entering the junction box 35, preventing short circuits or corrosion, extending the service life of the junction box 35, and ensuring the stable operation of the photovoltaic module 30 in harsh environments. Furthermore, the junction box 35's location within the heat dissipation space 101 also facilitates heat dissipation, reducing the possibility of overheating and damage, and ensuring the stability and reliability of the photovoltaic module 30's operation.

[0073] In some embodiments, the photovoltaic module 30 also includes an electrical connector, through which the junction boxes 35 of adjacent photovoltaic modules 31 are electrically connected.
