[0003] This application provides a photovoltaic module, a photovoltaic device, and a photovoltaic system to solve at least one of the aforementioned technical problems.

[0004] The photovoltaic module of this application includes a photovoltaic element and an mounting component. The mounting component includes a loading portion and protective portions disposed at opposite ends of the loading portion. The shape of the loading portion matches the shape of the photovoltaic element and is used to load the photovoltaic element. The protective portions are bent away from the loading portion relative to the loading portion. The protective portions are configured to connect to an external carrier. In the direction from the photovoltaic element to the loading portion, the free end of the protective portion is further away from the loading portion than the photovoltaic element.

[0005] In some embodiments, the protective part is a multi-segment bent structure, and the bending of the protective part forms a guide groove, which is used to guide the flow of fluid.

[0006] In some embodiments, the protective portion includes a first segment, a second segment, and a third segment. The first segment extends from the loading portion in a direction away from the photovoltaic element, the second segment extends from the first segment in a direction closer to the photovoltaic element, and the third segment extends from the second segment in a direction away from the loading portion. The first segment and the second segment together form the guide groove, and the end of the third segment away from the second segment is the free end of the protective portion.

[0007] In some embodiments, the protective part further includes a fourth segment connected between the first segment and the second segment, which together with the first segment and the second segment forms the guide groove.

[0009] In some embodiments, the mounting component includes a first region and a second region, the first region being used to mount the photovoltaic element, and the second region being connected to one end of the first region in a first direction perpendicular to the direction from the photovoltaic element to the mounting portion.

[0010] In some implementations, the size of the first region is larger than the size of the second region.

[0011] The photovoltaic device according to the embodiments of this application includes the photovoltaic module described in any of the above embodiments.

[0012] In some embodiments, the photovoltaic module comprises at least two, wherein the protective portions of two adjacent mounting members overlap each other in a second direction.

[0014] In the photovoltaic module, photovoltaic device, and photovoltaic system of this application, the mounting component includes a loading part and a protective part. The loading part can load the photovoltaic module, and in the direction from the photovoltaic module to the loading part, the free end of the protective part is farther away from the loading part than the photovoltaic module. That is, in the direction from the photovoltaic module to the loading part, the protective part is higher than the photovoltaic module. Therefore, when it is necessary to install or maintain the photovoltaic module, or when an external object falls on the photovoltaic module, the protective part can provide support, so that the photovoltaic module is protected from being stepped on or impacted by external objects, reducing the possibility of damage to the photovoltaic module and extending the service life of the photovoltaic module.

[0031] 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, PV modules can be installed on rooftops or other structures to convert solar energy into electricity, achieving energy conservation and environmental protection. However, when installing or maintaining PV modules, or when external objects (such as branches or hail) fall on them, the modules are easily damaged by being stepped on or impacted, affecting their lifespan. Please refer to [link / reference]. Figure 1 To address the aforementioned issues, this application provides a photovoltaic module 10, a photovoltaic device 100, and a photovoltaic system 1000.

[0032] Please see Figure 1 The photovoltaic system 1000 of this application includes a photovoltaic device 100 and a supporting device 300, with the photovoltaic device 100 disposed on the supporting device 300. It should be noted that, in some embodiments, the photovoltaic system 1000 may include, but is not limited to, photovoltaic roofs, photovoltaic carports, ground-mounted power stations, and floating photovoltaic systems.

[0033] Understandably, the support device 300 is a structure within the photovoltaic system 1000 used to fix, support, and adjust the photovoltaic device 100, ensuring that the photovoltaic device 100 can receive sunlight at an optimal angle and position, while also resisting the effects of environmental factors (such as wind, rain, and snow). The photovoltaic device 100 is a collection of components within the photovoltaic system 1000 used to convert solar energy into electrical energy. Specifically, the photovoltaic device 100 can convert solar energy into electrical energy, achieving sustainable energy utilization. The photovoltaic device 100 does not produce greenhouse gases such as carbon dioxide or pollutants during power generation, resulting in a low environmental impact. The photovoltaic device 100 helps reduce dependence on traditional energy sources, mitigating air pollution and climate change issues. The photovoltaic device 100 can be distributed and installed in various locations, such as rooftops, wastelands, and farmland, fully utilizing solar energy resources. This distributed layout helps reduce transmission losses and improves the stability and disaster resistance of the power system. The photovoltaic device 100 can be combined and expanded as needed, suitable for power generation systems of various sizes and requirements.

[0034] For example, the support device 300 may include structural components such as columns, beams, and purlins to provide a stable support platform for the photovoltaic device 100, enabling the photovoltaic device 100 to be installed on a roof, other locations on a building besides the roof, or other carriers. In some embodiments of this application, the photovoltaic system 1000 includes a photovoltaic roof. In this case, the support device 300 may be a purlin installed on the roof, and the photovoltaic device 100 can be installed on the roof via the support device 300.

[0035] In some embodiments, the photovoltaic device 100 can be detachably installed on the support device 300, which facilitates the removal of the photovoltaic device 100 from the support device 300 when maintenance or replacement is required. The detachable connection methods include, but are not limited to, bolt connections and snap-fit ​​connections. In other embodiments, the photovoltaic device 100 can be non-detachably installed on the support device 300, which improves the connection strength between the photovoltaic device 100 and the support device 300, enhances the photovoltaic system 1000's ability to withstand external environmental factors, and ensures the stability and reliability of the photovoltaic system 1000's operation. The non-detachable connection methods include, but are not limited to, bonding or welding.

[0036] Furthermore, in some embodiments, the photovoltaic system 1000 also includes an energy storage device electrically connected to the photovoltaic device 100. The energy storage device can store the electrical energy generated by the photovoltaic device 100 and can supply power to loads such as household appliances and portable devices. The energy storage device and the photovoltaic device 100 can be electrically connected via cables or through intermediate devices such as junction boxes or busbars. It should be noted that in some embodiments, the energy storage device 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.

[0037] Since the photovoltaic system 1000 in this embodiment includes the photovoltaic device 100, it is understood that the photovoltaic system 1000 includes at least the same beneficial effects as the photovoltaic device 100. Therefore, for the beneficial effects of the photovoltaic system 1000, please refer to the beneficial effects of the photovoltaic device 100 described below.

[0038] Please see Figure 1 The photovoltaic device 100 of the present application includes a photovoltaic module 10.

[0039] Furthermore, in some embodiments, the photovoltaic module 10 includes at least two modules, which are overlapped with each other. Specifically, at least two photovoltaic modules 10 can be overlapped sequentially in a specific direction to form an integral module (i.e., photovoltaic device 100), and then the integral module is installed on a roof or other carrier using a support device 300. This effectively improves installation efficiency while maximizing power generation. Moreover, forming an integral module from at least two photovoltaic modules 10 before installing the integral module on the roof using the support device 300 reduces high-altitude work on the roof and improves safety.

[0040] At least two photovoltaic modules 10 are connected to each other by overlapping, which makes the connection between adjacent photovoltaic modules 10 faster and more convenient, and facilitates the installation and disassembly of photovoltaic modules 10. This allows for faster and more efficient completion of work during installation and maintenance, improving work efficiency. In addition, at least two photovoltaic modules 10 can also be connected using fasteners (such as bolts) while overlapping, making the assembled photovoltaic device 100 more stable and improving the stability and reliability of the photovoltaic device 100 in operation.

[0041] It should be noted that in some embodiments, at least two photovoltaic modules 10 may have the same shape and size or different shapes. Users can select photovoltaic modules 10 with appropriate shapes and sizes according to specific usage requirements. For example, to accommodate the size of the carrier, users can select at least two photovoltaic modules 10 of different sizes.

[0042] Since the photovoltaic device 100 in this embodiment includes a photovoltaic module 10, it is understood that the photovoltaic device 100 includes at least the same beneficial effects as the photovoltaic module 10. Therefore, for the beneficial effects of the photovoltaic device 100, please refer to the beneficial effects of the photovoltaic module 10 described below.

[0043] Please see Figure 1 and Figure 2 In conjunction with Figure 3(a) or Figure 3(b), the photovoltaic module 10 of the present application embodiment includes a photovoltaic element 11 and a mounting element 13. The mounting element 13 includes a loading portion 131 and protective portions 133 disposed at opposite ends of the loading portion 131. The shape of the loading portion 131 matches the shape of the photovoltaic element 11 and is used to load the photovoltaic element 11. The protective portions 133 are bent away from the loading portion 131 relative to the loading portion 131. The protective portions 133 are configured to connect with an external carrier. In the direction from the photovoltaic element 11 to the loading portion 131, the free end of the protective portion 133 is further away from the loading portion 131 than the photovoltaic element 11.

[0044] It is understood that the photovoltaic element 11 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 11 with different efficiencies and sizes based on their usage needs and environmental conditions. In some embodiments of this application, the photovoltaic element 11 can have a planar or curved shape to adapt to different user needs, thereby better utilizing solar energy and improving the power generation efficiency of the photovoltaic module 10.

[0045] Mounting member 13 is a structure in photovoltaic module 10 used for lifting, mounting, and supporting structures such as photovoltaic element 11. In some embodiments of this application, mounting member 13 includes a loading part 131 and two protective parts 133. The loading part 131 is used to load the photovoltaic element 11, and the protective parts 133 are configured to connect to an external carrier (such as the support device 300 mentioned above). That is, the photovoltaic element 11 can be connected to the support device 300 through the protective parts 133 of mounting member 13. It should be noted that in some embodiments, the loading part 131 and the protective parts 133 can be an integral structure or separate structures, and this application does not impose any restrictions.

[0046] The shape of the loading part 131 matches the shape of the photovoltaic element 11. For example, when the photovoltaic element 11 is a planar structure, the loading part 131 is also a planar structure, and the shape of the loading part 131 is the same as the shape of the photovoltaic element 11. This allows the photovoltaic element 11 to be tightly connected to the loading part 131, reducing the risk of loosening or displacement and ensuring the normal operation of the photovoltaic module 10. On the other hand, it facilitates the positioning and installation of the photovoltaic element 11 on the mounting part 13, improving assembly efficiency.

[0047] In some embodiments, the mounting component 13 may 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 mounting component 13 may be made of metallic materials, such as aluminum alloys. This can improve the structural strength of the mounting component 13, enhance its ability to resist external environments, and ensure the stability and reliability of the photovoltaic module 10.

[0048] In some embodiments, the loading part 131 and the protective part 133 are made of the same material. For example, if the loading part 131 is made of aluminum alloy, the protective part 133 is also made of aluminum alloy, which facilitates the production and processing of the mounting part 13.

[0049] In other embodiments, the loading part 131 and the protective part 133 are made of different materials. For example, the loading part 131 may be made of a material with good heat insulation properties, such as glass wool or aerogel, thereby reducing the heat on the support device 300 or other carrier from being conducted to the photovoltaic element 11 through the loading part 131, preventing the photovoltaic element 11 from overheating and ensuring the power generation efficiency of the photovoltaic element 11; while the protective part 133 may be made of a metal with high structural strength, such as stainless steel, thereby improving the deformation resistance of the protective part 133, ensuring the protective effect of the protective part 133 on the photovoltaic element 11, and improving the stability and reliability of the photovoltaic module 10.

[0050] Specifically, in some embodiments, the photovoltaic element 11 includes a light-receiving surface and a back-lighting surface facing away from each other. The light-receiving surface is the surface of the photovoltaic element 11 that directly faces the sun, receives sunlight, and completes photoelectric conversion. The back-lighting surface is the surface of the photovoltaic element 11 that faces away from the sun. The photovoltaic element 11 may have only the light-receiving surface receiving sunlight and converting it into electrical energy to generate electricity; or, both the light-receiving and back-lighting surfaces of the photovoltaic element 11 may receive sunlight and convert it into electrical energy to generate electricity (e.g., the back-lighting surface may receive reflected light from the ground). In some embodiments of this application, in the direction from the photovoltaic element 11 to the loading portion 131, the free end of the protective portion 133 (the end of the protective portion 133 away from the connection between the protective portion 133 and the loading portion 131) is further away from the loading portion 131 than the photovoltaic element 11. That is, in the direction from the photovoltaic element 11 to the loading portion 131, the free end of the protective portion 133 is higher than the light-receiving surface of the photovoltaic element 11, thereby protecting the photovoltaic element 11, reducing the possibility of the photovoltaic element 11 being stepped on or hit by external objects, reducing the possibility of damage to the photovoltaic element 11, and extending the service life of the photovoltaic element 11.

[0051] In some embodiments, two protective portions 133 may be respectively disposed at opposite ends of the loading portion 131 in the second direction Y. In the second direction Y, the protective portions 133 of two adjacent mounting members 13 overlap each other. Therefore, on the one hand, two adjacent mounting members 13 can form a tighter overall structure through the protective portions 133, thereby improving the wind and earthquake resistance of the photovoltaic module 10 and enhancing the stability and reliability of the photovoltaic device 100; on the other hand, it makes the alignment and connection of two adjacent mounting members 13 more convenient, improving assembly efficiency; and furthermore, the superposition of the two protective portions 133 can enhance the deformation resistance of the protective portions 133, improving the protective effect.

[0052] In the photovoltaic module 10 of this application embodiment, the mounting member 13 includes a loading part 131 and a protective part 133. The loading part 131 can load the photovoltaic module 11, and in the direction from the photovoltaic module 11 to the loading part 131, the free end of the protective part 133 is farther away from the loading part 131 than the photovoltaic module 11. That is, in the direction from the photovoltaic module 11 to the loading part 131, the protective part 133 is higher than the photovoltaic module 11. Therefore, when it is necessary to install or maintain the photovoltaic module 11, or when an external object falls on the photovoltaic module 10, the protective part 133 can provide support, so that the photovoltaic module 11 is protected from being stepped on or impacted by external objects, reducing the possibility of damage to the photovoltaic module 11 and extending the service life of the photovoltaic module 11.

[0053] In addition, the mounting component 13 includes a loading part 131 and a protective part 133. The loading part 131 can load the photovoltaic component 11, and the protective part 133 can be connected to the external carrier. In other words, the photovoltaic component 11 can be installed on the external carrier through the mounting component 13. That is, the photovoltaic component 11 has its own installation structure and better resistance to deformation. This can avoid the photovoltaic component 11 being difficult to install on the carrier due to easy deformation, reduce the installation difficulty of the photovoltaic component 11, and improve the installation efficiency.

[0054] In addition, please combine Figure 1 When the photovoltaic system 1000 includes a photovoltaic house, if there is too much snow on the roof and the photovoltaic module 10 is a planar structure, the snow will slide off the roof under gravity, potentially causing injury to the user. However, in some embodiments of this application, when the photovoltaic house is assembled, the angle between the second direction Y and the direction of gravity is less than 90°. That is, the photovoltaic module 10 can be tilted on the roof. In this case, the free end of the protective part 133 is further away from the mounting part 131 than the photovoltaic component 11. In other words, in the direction from the photovoltaic component 11 to the mounting part 131, the protective part 133 is higher than the light-receiving surface of the photovoltaic component 11. This allows the protective part 133 to act as a snow deflector, reducing or even preventing snow from sliding directly off the roof, lowering the possibility of injury to the user, and improving the safety of the photovoltaic system 1000.

[0055] The photovoltaic module 10 will be further explained below with reference to the attached diagram.

[0056] Please see Figure 2Referring to Figure 3(a) or Figure 3(b), in some embodiments, the protective part 133 has a multi-segment bent structure, and the bending of the protective part 133 forms a guide groove 1330, which is used to guide fluid flow. It should be noted that in some embodiments, the cross-sectional shape of the guide groove 1330 includes, but is not limited to, V-shape, U-shape, square, trapezoidal, and semi-circular. The guide groove 1330 can be an open groove, and the opening of the guide groove 1330 communicates with the outside, thereby facilitating the guide groove 1330 to guide the fluid falling on the photovoltaic module 10, reducing or even avoiding fluid accumulation on the photovoltaic module 10.

[0057] The multi-segment bending structure is a structure composed of at least two bending segments, each connected by a certain angle or curvature. That is, the protective part 133 is a structure composed of at least two bending segments, thereby improving the adaptability of the mounting component 13 and ensuring its proper assembly in different installation scenarios. Specifically, the at least two bending segments of the protective part 133 can jointly form a guide groove 1330. The guide groove 1330 guides rainwater, snow water, or cleaning liquids on the photovoltaic module 10, allowing the fluid to flow quickly down the photovoltaic module 10 and preventing fluid accumulation. This avoids fluid soaking of the photovoltaic module 11, which could reduce its light absorption capacity and ensure the power generation efficiency of the photovoltaic module 10. Furthermore, it prevents fluid from seeping into the interior of the photovoltaic module 11, reducing the possibility of damage and extending its service life.

[0058] Please see Figure 2 As shown in Figure 3(a), in some embodiments, the protective portion 133 includes a first segment 1331, a second segment 1333, and a third segment 1335. The first segment 1331 extends from the loading portion 131 in a direction away from the photovoltaic element 11, the second segment 1333 extends from the first segment 1331 in a direction close to the photovoltaic element 11, and the third segment 1335 extends from the second segment 1333 in a direction away from the loading portion 131. The first segment 1331 and the second segment 1333 together form a guide groove 1330, and the end of the third segment 1335 away from the second segment 1333 is the free end of the protective portion 133.

[0059] Specifically, in some embodiments, the second segment 1333 extends from the end of the first segment 1331 away from the loading part 131 towards the photovoltaic element 11, and the third segment 1335 extends from the end of the second segment 1333 away from the first segment 1331 along the second direction Y towards the direction away from the loading part 131. In the second direction Y, adjacent protective parts 133 can overlap through the third segment 1335; that is, the third segments 1335 of adjacent protective parts 133 are stacked to allow at least two photovoltaic modules 10 to overlap along the second direction Y to form an integral structure. It is understood that the mounting member 13 can connect with the support device 300 through the third segment 1335 of the protective part 133. Figure 1 (as shown) or other external carriers for connection.

[0060] It should be noted that in some embodiments, the first segment 1331 and the second segment 1333 are smoothly connected, thereby eliminating the gap between the first segment 1331 and the second segment 1333, making the inner wall surface of the guide groove 1330 more continuous and flat, reducing the accumulation of dust, dirt and liquid at the connection between the first segment 1331 and the second segment 1333, and making it easier to clean and reducing the difficulty of cleaning.

[0061] Furthermore, in some embodiments, when the third segments 1335 of two adjacent protective portions 133 overlap along the second direction Y, a sealing member may be provided between the third segments 1335 of the two adjacent protective portions 133. The sealing member is used to seal the gap between the third segments 1335 of the two adjacent protective portions 133. For example, in a photovoltaic system 1000 (… Figure 1 In the case of a photovoltaic roof (as shown), the sealing element can prevent liquid on the protective part 133 from leaking into the house through the gap between the third section 1335 of the two protective parts 133, thereby improving the user experience.

[0062] Understandably, since the first segment 1331 of the protective part 133 bends away from the photovoltaic element 11 relative to the mounting part 131, the mounting part 131 and the first segments 1331 of the two protective parts 133 can form a space together. Therefore, compared to the photovoltaic element 11 being laid flat on the external carrier, when the photovoltaic element 11 is set on the external carrier by the mounting part 13, the space formed by the mounting part 131 and the first segments 1331 of the two protective parts 133 can allow air circulation, thereby improving the heat dissipation effect of the photovoltaic module 10 and reducing the possibility of the photovoltaic element 11 overheating. This ensures the stable operation of the photovoltaic element 11 and improves the power generation efficiency of the photovoltaic element 11, while also preventing the photovoltaic element 11 from overheating and being damaged, thus extending the service life of the photovoltaic element 11.

[0063] Please see Figure 2As shown in Figure 3(b), in some embodiments, the protective part 133 further includes a fourth segment, which is connected between the first segment 1331 and the second segment 1333, and together with the first segment 1331 and the second segment 1333, forms a guide groove 1330.

[0064] Specifically, in some embodiments, the fourth segment may extend from the end of the first segment 1331 away from the loading part 131 along the second direction Y in a direction away from the loading part 131, and the second segment 1333 may extend from the end of the fourth segment away from the first segment 1331 in a direction close to the photovoltaic element 11. Thus, the first segment 1331, the fourth segment, and the second segment 1333 can jointly form a guide groove 1330. Compared with the first segment 1331 and the second segment 1333 jointly forming the guide groove 1330, the guide groove 1330 is larger in size, thereby improving the guiding effect of fluid and making it easier for the user to clean the guide groove 1330.

[0065] It should be noted that in some embodiments, the first segment 1331 and the fourth segment, as well as the second segment 1333 and the fourth segment, are smoothly connected, thereby making the inner wall surface of the guide groove 1330 more continuous and flat, reducing the accumulation of dust, dirt and liquid at the connection between the first segment 1331 and the fourth segment, and at the connection between the second segment 1333 and the fourth segment, and making it easier to clean and reducing the difficulty of cleaning.

[0066] Please see Figure 1 As shown in Figure 3, in some embodiments, the protective part 133 and the loading part 131 form an installation space 130. The photovoltaic module 10 also includes a junction box 15, which is disposed within the installation space 130 and electrically connected to the photovoltaic element 11. It should be noted that in other embodiments, the protective part 133 may also be configured to participate in forming the installation space 130, that is, when two adjacent protective parts 133 are connected, the two adjacent protective parts 133 together form the installation space 130.

[0067] Understandably, the junction box 15 is a component in the photovoltaic module 10 that serves as an electrical connection. The junction box 15 can be electrically connected to the photovoltaic module 11 and the energy storage device to form a complete electrical circuit, enabling the electrical energy generated by the photovoltaic module 11 to be transmitted to the energy storage device. The installation space 130 provides protection for the junction box 15, reducing the possibility of liquids or dust entering the junction box 15, preventing short circuits or corrosion, extending the service life of the junction box 15, and ensuring the stable operation of the photovoltaic module 10 in harsh environments.

[0068] In some embodiments, the photovoltaic module 10 also includes an electrical connector, and the junction boxes 15 of adjacent photovoltaic modules 10 are electrically connected via electrical connection lines. Specifically, when there are at least two photovoltaic modules 10, the junction boxes 15 of at least two photovoltaic modules 10 can be connected together in series or parallel via electrical connection lines, which facilitates the control of functions such as charging or discharging of the photovoltaic device 100 and improves the stability and reliability of the photovoltaic device 100 operation.

[0069] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the mounting component 13 includes a first region 135 and a second region 137. The first region 135 is used to mount the photovoltaic element 11, and the second region 137 is connected to one end of the first region 135 in a first direction X, which is perpendicular to the direction from the photovoltaic element 11 to the mounting portion 131. It should be noted that the first direction X is perpendicular to the second direction Y. The first direction X and the second direction Y can be the length direction and the width direction of the photovoltaic module 10, respectively.

[0070] Specifically, referring to Figure 3(a) or Figure 3(b), in some embodiments, in the third direction Z (a direction perpendicular to both the first direction X and the second direction Y), the mounting member 13 includes a first side 138 and a second side 139 facing away from each other, and the photovoltaic element 11 is disposed on the first side 138 of the mounting member 13. In the first direction X, one mounting member 13 can overlap with the second area 137 of an adjacent mounting member 13. At this time, the second side 139 of one mounting member 13 is connected to the area on the first side 138 of the adjacent mounting member 13 corresponding to the second area 137. That is, the second area 137 can be used to connect two adjacent photovoltaic modules 10 in the first direction X, thereby allowing at least two photovoltaic modules 10 to overlap sequentially along the first direction X to form an integral module.

[0071] For example, please refer to Figure 4 When there are multiple photovoltaic modules 10, the multiple photovoltaic modules 10 can be sequentially overlapped along the first direction X via the second region 137 of their respective mounting members 13 to form at least two integral modules (hereinafter referred to as first integral modules); subsequently, the at least two first integral modules can be sequentially overlapped along the second direction Y via the guide portion of the mounting member 13 of each photovoltaic module 10 to finally form a photovoltaic device 100; or,

[0072] Please combine Figure 5When there are multiple photovoltaic modules 10, the multiple photovoltaic modules 10 can be sequentially overlapped along the second direction Y through the guide portion of their respective mounting parts 13 to form at least two integral modules (hereinafter referred to as second integral modules); subsequently, the at least two second integral modules can be sequentially overlapped along the first direction X through the second area 137 of the mounting parts 13 of each photovoltaic module 10 to finally form a photovoltaic device 100.

[0073] Understandably, connecting two adjacent photovoltaic modules 10 by overlapping facilitates their installation and disassembly, enabling faster and more efficient installation and maintenance, thus improving work efficiency. Furthermore, adjacent photovoltaic modules 10 can be connected using fasteners (such as bolts) to ensure the connection strength between them and enhance the stability of the photovoltaic device 100.

[0074] Please see Figure 1 , Figure 2 , Figure 4 and Figure 5 In some embodiments, the photovoltaic module 10 includes multiple modules, each including a first photovoltaic module 101 and a second photovoltaic module 103. In the first direction X, the second photovoltaic module 103 overlaps the first photovoltaic module 101. That is, referring to Figure 3(a) or Figure 3(b), the second side 139 of the mounting member 13 of the second photovoltaic module 103 is connected to the first side 138 of the mounting member 13 of the first photovoltaic module 101. It should be noted that in some embodiments, the second photovoltaic module 103 may be the photovoltaic module 10 located at the leftmost end of the photovoltaic device 100 in the figure.

[0075] Specifically, in some embodiments, the mounting member 13 of the first photovoltaic module 101 (hereinafter referred to as the first mounting member) includes a first region 135 and a second region 137. The first region 135 of the first mounting member is used to support the photovoltaic element 11, and the second region 137 of the first mounting member is not used to support the photovoltaic element 11. The mounting member 13 of the second photovoltaic module 103 (hereinafter referred to as the second mounting member) includes a first region 135 and two second regions 137. Both the first region 135 and the second region 137 of the second mounting member are used to support the photovoltaic element 11. Thus, when the first photovoltaic module 101 and the second photovoltaic module 103 are sequentially overlapped along the first direction X, the photovoltaic elements 11 of the first photovoltaic module 101 and the photovoltaic elements 11 of the second photovoltaic module 103 can be connected into a whole. In this case, the user cannot see the mounting member 13 through the gap between the photovoltaic elements 11 of the first photovoltaic module 101 and the photovoltaic elements 11 of the second photovoltaic module 103. This reduces visual defects and improves the aesthetics of the photovoltaic device 100. On the other hand, it increases the size of the photovoltaic element 11 and improves the power generation efficiency of the photovoltaic device 100.

[0076] Furthermore, in some embodiments, the thickness of the second region 137 of the mounting member 13 is less than the thickness of the first region 135 of the mounting member 13, so that when at least two photovoltaic modules 10 are sequentially overlapped along the first direction X, the light-receiving surfaces of the photovoltaic elements 11 of the two adjacent photovoltaic modules 10 are flush.

[0077] It is understood that when there are at least two first photovoltaic modules 101, at least two first photovoltaic modules 101 can be sequentially connected through the second zone 137. That is, the mounting piece 13 of one first photovoltaic module 101 can be connected to the second zone 137 of the mounting piece 13 of another adjacent first photovoltaic module 101. The light-receiving surfaces of two adjacent first photovoltaic modules 101 are flush.

[0078] In some embodiments, the size of the first region 135 is larger than the size of the second region 137. It is understood that in some embodiments of this application, the size of the mounting portion 131 in the first region 135 is the same as the size of the photovoltaic element 11. Therefore, having the first region 135 larger than the second region 137 ensures that the photovoltaic element 11 is larger, thereby increasing the power generation of the photovoltaic module 10 and increasing the amount of electricity generated.
