Description

Technical Field

[0001] This application relates to the field of photovoltaic technology, and more specifically, to a photovoltaic module, a photovoltaic device, and a photovoltaic system. Background Technology

[0002] 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) devices can be installed on rooftops or other carriers to convert solar energy into electrical energy, achieving energy conservation and environmental protection. Generally, PV devices can be directly laid on the surface of the carrier, with adjacent PV devices abutting each other to form a unified structure. However, when fluids are present on the PV devices, the fluids can easily accumulate at the joints between adjacent PV devices and penetrate into the PV devices, causing damage and affecting their lifespan. Utility Model Content

[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 at least two photovoltaic elements and at least one support element. The at least two photovoltaic elements are spaced apart along a first direction. The support element is configured to connect to an external carrier. In the first direction, the support element is disposed between two adjacent photovoltaic elements and is used to support the two adjacent photovoltaic elements. Each support element and the corresponding photovoltaic element together form a guide groove, which is used to guide fluid flow.

[0005] In some embodiments, the photovoltaic element includes a body portion and two bent portions that bend relative to the body portion. The two bent portions are respectively connected to opposite ends of the body portion in the first direction. The bent portions overlap the support member and together with the support member form the guide groove.

[0006] In some embodiments, the support member includes a main body and two support portions, the two support portions being respectively connected to opposite ends of the main body in the first direction, the support portions being bent relative to the main body toward the photovoltaic element, and the support portions being used for overlapping the bent portions.

[0007] In some embodiments, the photovoltaic element further includes a battery layer; the photovoltaic element includes a loading area and a connecting area, the loading area being used to load the battery layer, and the connecting area being connected to one end of the loading area in a second direction, the second direction being perpendicular to the first direction.

[0008] In some implementations, the size of the loading area is larger than the size of the connecting area.

[0009] In some embodiments, the photovoltaic module further includes at least two junction boxes, which are electrically connected to at least two photovoltaic elements in a one-to-one correspondence; the junction boxes are disposed on the support member.

[0010] In some embodiments, the photovoltaic module further includes at least two junction boxes, which are electrically connected to at least two photovoltaic elements in a one-to-one correspondence; the photovoltaic elements form an installation space, and the junction boxes are disposed within the installation space.

Furthermore, a support member is disposed between two adjacent photovoltaic elements to support them. Each support member and the corresponding photovoltaic element together form a guide groove, which is used to guide fluid flow. That is, the guide groove can guide the fluid on the photovoltaic module, preventing the fluid from accumulating on the photovoltaic module or at the seam between two adjacent photovoltaic elements, thus preventing the fluid from seeping into the interior of the photovoltaic element. This reduces the possibility of damage to the photovoltaic element, extends the service life of the photovoltaic element, and ensures the normal operation of the photovoltaic element.

[0029] 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) modules can be installed on rooftops or other carriers to convert solar energy into electrical energy, achieving energy conservation and environmental protection. Generally, PV modules can be directly laid on the surface of the carrier, with adjacent modules abutting each other to form a single structure. However, when fluid is present on the PV modules, it accumulates at the joints between adjacent modules and seeps into the modules, causing damage and 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.

[0030] 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 houses, photovoltaic carports, ground-mounted power stations, and floating photovoltaic systems.

[0031] 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.

[0032] 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 through the support device 300 to jointly form a photovoltaic roof.

[0033] 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.

[0034] 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 power loads such as household appliances and portable devices. Of course, the photovoltaic device 100 can also directly power 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 15 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.

[0035] 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.

[0036] Please see Figure 1 and Figure 2 The photovoltaic device 100 of the present application includes a photovoltaic module 10.

[0037] Furthermore, in some embodiments, the photovoltaic module 10 includes at least two modules. Specifically, at least two photovoltaic modules 10 can be sequentially connected 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 via a support device 300. This effectively improves installation efficiency while maximizing power generation. Moreover, forming at least two photovoltaic modules 10 into an integral module before installing the integral module on the roof via the support device 300 reduces high-altitude work on the roof and improves safety.

[0038] For example, at least two photovoltaic modules 10 can be 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.

[0039] 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.

[0040] Please see Figure 1 and Figure 2 The photovoltaic module 10 of this application includes at least two photovoltaic elements 11 and at least one support member 13. The at least two photovoltaic elements 11 are spaced apart along a first direction X. The support member 13 is configured to connect to an external carrier. In the first direction X, the support member 13 is disposed between two adjacent photovoltaic elements 11 and is used to support the two adjacent photovoltaic elements 11. Each support member 13 and the corresponding photovoltaic element 11 together form a guide groove 105, which is used to guide fluid flow.

[0041] 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. The photovoltaic element 11 can have a planar structure, a bent structure, or a curved surface structure to adapt to different user needs, achieving better utilization of solar energy and improving the power generation efficiency of the photovoltaic module 10.

[0042] Specifically, please combine Figure 3In some embodiments, the photovoltaic element 11 includes a light-receiving surface 117 and a backlighting surface 118 facing away from each other. The light-receiving surface 117 is the surface of the photovoltaic element 11 that directly faces the sun, receives sunlight, and completes photoelectric conversion. The backlighting surface 118 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 117 receiving sunlight and converting it into electrical energy to generate electricity; or, both the light-receiving surface 117 and the backlighting surface 118 of the photovoltaic element 11 may receive sunlight and convert it into electrical energy to generate electricity (e.g., the backlighting surface 118 may receive reflected light from the ground).

[0043] The support member 13 is a structure in the photovoltaic module 10 used to provide installation and support for structures such as photovoltaic elements 11. In some embodiments of this application, the support member 13 is configured to connect to an external carrier (such as the support device 300 described above), and in the first direction X, a support member 13 is provided between two adjacent photovoltaic elements 11, which can support the two adjacent photovoltaic elements 11, thereby allowing the photovoltaic elements 11 to be installed on the external carrier via the support member 13. It should be noted that in some embodiments, the connection method between the support member 13 and the photovoltaic element 11 includes, but is not limited to, overlapping, bonding, bolting, snap-fit ​​connection, welding, etc.

[0044] In some embodiments, the support member 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 support member 13 may be made of metallic materials, such as aluminum alloys. This can improve the structural strength of the support member 13, enhance its ability to resist external environments, and ensure the stability and reliability of the photovoltaic module 10.

[0045] Each support member 13 and its corresponding photovoltaic element 11 together form a guide groove 105. That is, in the first direction X, two adjacent photovoltaic elements 11 and the support member 13 located between the two adjacent photovoltaic elements 11 together form a guide groove 105. Specifically, the guide groove 105 can guide fluids such as 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 from accumulating on the photovoltaic module 10. This avoids the photovoltaic element 11 from being soaked by fluid, which would reduce its ability to absorb light, thus ensuring the power generation efficiency of the photovoltaic module 10. On the other hand, it prevents fluid from seeping into the interior of the photovoltaic element 11, thereby reducing the possibility of damage to the photovoltaic element 11 and extending its service life. It should be noted that in some embodiments, the guide groove 105 may be an open groove; the cross-sectional shape of the guide groove 105 includes, but is not limited to, V-shape, U-shape, square, trapezoidal, and semi-circular.

[0046] In the photovoltaic module 10 of this application embodiment, at least two photovoltaic elements 11 are arranged at intervals along a first direction X, so that there is no seam between two adjacent photovoltaic elements 11. Furthermore, a support member 13 is disposed between two adjacent photovoltaic elements 11 to support the two adjacent photovoltaic elements 11. Each support member 13 and the corresponding photovoltaic element 11 together form a guide groove 105. The guide groove 105 is used to guide fluid flow. That is, the guide groove 105 can guide the fluid on the photovoltaic module 10, avoid the fluid from accumulating on the photovoltaic module 10 or at the seam between two adjacent photovoltaic elements 11, which would cause the fluid to seep into the interior of the photovoltaic element 11, reduce the possibility of damage to the photovoltaic element 11, extend the service life of the photovoltaic element 11, and ensure the normal operation of the photovoltaic element 11.

[0047] In addition, at least two photovoltaic elements 11 are spaced apart along the first direction X, and a support member 13 is provided between two adjacent photovoltaic elements 11. Thus, when it is necessary to install or maintain the photovoltaic elements 11, the support member 13 is used for users to step on, thereby protecting the photovoltaic elements 11 from being stepped on, reducing the possibility of damage to the photovoltaic elements 11, and extending the service life of the photovoltaic elements 11.

[0048] The photovoltaic module 10 will be further explained below with reference to the attached diagram.

[0049] Please see Figure 2 and Figure 3 In some embodiments, the photovoltaic element 11 includes a body portion 111 and two bent portions 112 that bend relative to the body portion 111. The two bent portions 112 are respectively connected to opposite ends of the body portion 111 in the first direction X. The bent portions 112 overlap with the support member 13 and together with the support member 13 form a guide groove 105.

[0050] The bending portion 112 can enhance the structural strength of the photovoltaic element 11, reduce the possibility of deformation under stress, and improve the stability and reliability of the photovoltaic element 11. On the other hand, it can guide the fluid on the photovoltaic element 11, allowing it to flow quickly into the guide groove 105, preventing the fluid from accumulating on the photovoltaic element 11 and causing damage to the photovoltaic element 11, thereby extending the service life of the photovoltaic element 11.

[0051] Understandably, the bending portion 112 can bend relative to the main body 111 towards the support member 13. When the bending portion 112 overlaps the support member 13, the main body 111 and the two bending portions 112 can form a space together. Therefore, compared to the photovoltaic module 11 being laid flat on the external carrier, when the photovoltaic module 11 is set on the external carrier through the support member 13, the space formed by the main body 111 and the two bending portions 112 can allow air circulation, thereby improving the heat dissipation effect of the photovoltaic module 10 and reducing the possibility of the photovoltaic module 11 overheating. This ensures the stable operation of the photovoltaic module 11 and improves the power generation efficiency of the photovoltaic module 11. On the other hand, it prevents the photovoltaic module 11 from overheating and being damaged, thus extending the service life of the photovoltaic module 11.

[0052] Furthermore, in some embodiments, the support member 13 includes a main body 131 and two support portions 133. The two support portions 133 are respectively connected to opposite ends of the main body 131 in the first direction X. The support portions 133 are bent relative to the main body 131 toward the photovoltaic element 11, and are used for overlapping of the bent portion 112. It should be noted that in some embodiments, the main body 131 and the support portions 133 may be an integral structure or a separate structure, and this application does not impose any limitations.

[0053] Specifically, in some embodiments, the main body 131 is configured to connect with an external carrier, and two support parts 133 are respectively used for overlapping the bent portions 112 of two adjacent main body parts 111 in the first direction X, so as to realize the support member 13 supporting two adjacent photovoltaic modules 11. When the bent portion 112 overlaps with the support part 133, the bent portion 112, the main body 131, and the support part 133 can jointly form the guide groove 105. The shape of the support part 133 can match the shape of the bent portion 112. For example, when the bent portion 112 is a flat plate structure, the support part 133 is also a flat plate structure, thereby ensuring a tight fit between the support part 133 and the bent portion 112. This reduces the risk of loosening or displacement, ensuring the normal operation of the photovoltaic module 10, and improves the sealing of the guide groove 105, reducing the possibility of fluid leakage in the guide groove 105 through the gap between the support part 133 and the bent portion 112.

[0054] It should be noted that in some embodiments, the main body 131 and the support 133 are smoothly connected, thereby eliminating the gap between the main body 131 and the support 133, making the inner wall surface of the guide groove 105 more continuous and flat, reducing the accumulation of dust, dirt and liquid at the connection between the main body 131 and the support 133, and making it easier to clean and reducing the difficulty of cleaning.

[0055] Furthermore, please combine Figure 1In some embodiments, when the bend 112 overlaps the support 133, a seal may be provided between the bend 112 and the support 133 to seal the gap between them. For example, in the case where the photovoltaic system 1000 includes a photovoltaic roof, the photovoltaic device 100 can be mounted on the roof via the support device 300 to form a photovoltaic roof. In this case, the seal prevents fluid in the guide channel 105 from leaking into the roof through the gap between the bend 112 and the support 133, thereby improving the user experience.

[0056] In some embodiments, the main body 131 and the support 133 are made of the same material. For example, if the main body 131 is made of aluminum alloy, the support 133 is also made of aluminum alloy, which facilitates the production and processing of the support 13.

[0057] In other embodiments, the main body 131 and the support 133 are made of different materials. For example, the main body 131 may be made of a material with good heat insulation properties, such as glass wool or aerogel, thereby reducing the heat conducted from the support device 300 or other carrier to the photovoltaic element 11 through the main body 131, preventing the photovoltaic element 11 from overheating and ensuring the power generation efficiency of the photovoltaic element 11; while the support 133 may be made of a metal with high structural strength, such as stainless steel, thereby improving the deformation resistance of the support 133, ensuring the stability of the support 133 in supporting the photovoltaic element 11, and improving the stability and reliability of the photovoltaic module 10.

[0058] Please see Figure 2 and Figure 3 In some embodiments, the photovoltaic element 11 further includes a battery layer 113. The battery layer 113 is a component in the photovoltaic element 11 used to convert solar energy into electrical energy. The battery layer 113 includes, but is not limited to, crystalline silicon batteries and thin-film batteries. It should be noted that in some embodiments of this application, the battery layer 113 is disposed on the body portion 111 of the photovoltaic element 11.

[0059] Specifically, in some embodiments, the battery layer 113 and the body portion 111 are sequentially stacked in the direction from the light-receiving surface 117 to the backlighting surface 118. More specifically, in some embodiments, the photovoltaic element 11 further includes a cover plate 114, which is also sequentially stacked with the body portion 111 in the direction from the light-receiving surface 117 to the backlighting surface 118, with the battery layer 113 connected between the cover plate 114 and the body portion 111. The cover plate 114 and the body portion 111 together protect the battery layer 113 and other internal components of the photovoltaic element 11 from external physical impacts and environmental corrosion, reducing the possibility of damage to the photovoltaic element 11. The battery layer 113 and the cover plate 114, as well as the battery layer 113 and the body portion 111, can be connected together with an adhesive film to form a stable and robust structure, improving the overall structural stability. It should be noted that the cover plate 114 and the body part 111 may be made of at least one of the following materials: glass, PET, metal, composite fiber, etc.; the adhesive film may be made of at least one of the following materials: EVA, POE, PVB, etc.

[0060] Please combine Figure 1 In some embodiments, the photovoltaic element 11 includes a loading area 115 and a connecting area 116. The loading area 115 is used to load the battery layer 113, and the connecting area 116 is connected to one end of the loading area 115 in a second direction Y, which is perpendicular to the first direction X.

[0061] Specifically, in some embodiments, at least two photovoltaic modules 10 are sequentially overlapped along the second direction Y. In other words, a photovoltaic element 11 in one photovoltaic module 10 can overlap with the connection area 116 of a photovoltaic element 11 in an adjacent photovoltaic module 10. In this case, the backlight surface 118 of one photovoltaic element 11 is connected to the area on the light-receiving surface 117 of the adjacent photovoltaic element 11 that corresponds to the connection area 116. That is, the connection area 116 can be used to connect two adjacent photovoltaic modules 10 in the second direction Y, thereby enabling at least two photovoltaic modules 10 to jointly form an integral module. It should be noted that when at least two photovoltaic modules 10 are sequentially overlapped along the second direction Y, the support members 13 in two adjacent photovoltaic modules 10 can also be sequentially overlapped in the second direction Y to achieve the connection of the guide groove 105.

[0062] 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.

[0063] In other embodiments, in the second direction Y, the end of one photovoltaic element 11 can abut against the end of the connection area 116 of another adjacent photovoltaic element 11, thereby allowing at least two photovoltaic modules 10 to be sequentially spliced ​​along the second direction Y to form an integral module. For ease of understanding, the embodiments of this application are described using the example of at least two photovoltaic modules 10 being sequentially overlapped along the second direction Y.

[0064] Please see Figures 1 to 3 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 second direction Y, the second photovoltaic module 103 is attached to the first photovoltaic module 101. That is, the backlight surface 118 of the photovoltaic element 11 of the second photovoltaic module 103 is connected to the light-receiving surface 117 of the photovoltaic element 11 of the first photovoltaic module 101. It should be noted that in some embodiments, the second photovoltaic module 103 may be... Figure 1 The photovoltaic module 10 is located at the top of the photovoltaic device 100.

[0065] Specifically, in some embodiments, the photovoltaic element 11 (hereinafter referred to as the first photovoltaic element) of the first photovoltaic module 101 includes a loading area and a connecting area. The loading area of ​​the first photovoltaic element is used to support the photovoltaic element 11, while the connecting area of ​​the first photovoltaic element is not used to support the photovoltaic element 11. The photovoltaic element 11 (hereinafter referred to as the second photovoltaic element) of the second photovoltaic module 103 includes a loading area and a connecting area. Both the loading area and the connecting area of ​​the second photovoltaic element 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 second direction Y, the first photovoltaic element and the second photovoltaic element can be connected into a whole. In this case, the user cannot see the support device 300 or other structures through the gap between the first photovoltaic element and the second photovoltaic element, thereby reducing visual defects and improving the aesthetics of the photovoltaic device 100. On the other hand, compared to the second photovoltaic element where the loading area is used to support the photovoltaic element 11 but the connecting area is not used to support the photovoltaic element 11, the photovoltaic element 11 in this embodiment is larger in size, thereby improving the power generation efficiency of the photovoltaic device 100.

[0066] Furthermore, in some embodiments, the thickness of the connection area 116 of the photovoltaic element 11 is less than the thickness of the loading area 115 of the photovoltaic element 11, and when at least two photovoltaic modules 10 are sequentially overlapped along the second direction Y, the light-receiving surfaces 117 of the photovoltaic elements 11 of the two adjacent photovoltaic modules 10 are flush.

[0067] It is understood that when there are at least two first photovoltaic modules 101, at least two first photovoltaic modules 101 can be connected sequentially through the connection area 116, that is, one first photovoltaic module can be connected to the connection area of ​​another adjacent first photovoltaic module. The light-receiving surfaces 117 of two adjacent first photovoltaic modules 101 are flush.

[0068] In some embodiments, the size of the loading area 115 is larger than the size of the connecting area 116. It is understood that in some embodiments of this application, the size of the body portion 111 in the loading area 115 is the same as the size of the photovoltaic element 11. Therefore, having a larger size for the loading area 115 than for the connecting area 116 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.

[0069] Please see Figure 2 and Figure 3 In some embodiments, the photovoltaic module 10 further includes at least two junction boxes 15, which are electrically connected to at least two photovoltaic elements 11 in a one-to-one correspondence. It is understood that the junction box 15 is a component in the photovoltaic module 10 used for electrical connection. The junction box 15 can be electrically connected to the photovoltaic element 11 and the energy storage device to form a complete electrical circuit, enabling the electrical energy generated by the photovoltaic element 11 to be transmitted to the energy storage device.

[0070] Specifically, in some embodiments, the junction box 15 is disposed on the support member 13. In other embodiments, the photovoltaic module 11 forms an installation space 110, and the junction box 15 is disposed within the installation space 110. The installation space 110 may be the space formed by the main body 111 and the two bent portions 112. The installation space 110 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.

[0071] In some embodiments, the photovoltaic module 10 further includes an electrical connector, through which at least two junction boxes 15 are electrically connected. Specifically, when the photovoltaic module 10 includes at least two modules, the junction boxes 15 in the at least two photovoltaic modules 10 can be connected together in series or parallel via the electrical connector, thereby facilitating the connection of the photovoltaic device 100. Figure 1 (As shown) to control functions such as charging or discharging, thereby improving the stability and reliability of the photovoltaic device 100.
