[0030] In the related art, photovoltaic devices can be installed on a roof or other carrier and used to convert solar energy into electrical energy for the purpose of energy saving, environmental protection, etc. However, since the photovoltaic devices are usually made of lightweight materials, when directly installing the photovoltaic devices on the carrier such as a roof, the photovoltaic devices made of lightweight materials are prone to deformation. In order to ensure the installation fit and stability of the photovoltaic devices and the carrier, specific tools or specific installation methods need to be used, resulting in complex installation of the photovoltaic devices. Please refer to Figure 1 To solve the above problems, the embodiments of the present application provide a photovoltaic module 10, a photovoltaic device 100 and a photovoltaic system 1000.

[0031] Please refer to Figure 1 The photovoltaic system 1000 of the embodiments of the present application includes a photovoltaic device 100 and a support device 300, and the photovoltaic device 100 is arranged on the support device 300. It should be noted that in some embodiments, the photovoltaic system 1000 can include but is not limited to a photovoltaic roof, a photovoltaic carport, a ground power station, and a water surface photovoltaic system, etc.

[0032] It can be understood that the support device 300 is a structure in the photovoltaic system 1000 for fixing, supporting and adjusting the photovoltaic device 100, ensuring that the photovoltaic device 100 can receive light at a better angle and position, while being able to resist the influence of environmental factors such as wind, rain, snow, etc. The photovoltaic device 100 is a collection of components in the photovoltaic system 1000 for converting solar energy into electrical energy. Among them, the photovoltaic device 100 can convert solar energy into electrical energy, realizing sustainable energy utilization. The photovoltaic device 100 generates electricity without producing greenhouse gases such as carbon dioxide and pollutants, and has a relatively small environmental load. The photovoltaic device 100 helps to reduce dependence on traditional energy sources, reduce air pollution and climate change problems. The photovoltaic device 100 can be installed in various places such as roofs, wastelands, farmlands, etc. in a distributed manner, making full use of solar energy resources. This scattered layout helps to reduce power transmission losses and improve the stability and disaster resistance of the power system. The photovoltaic device 100 can be combined and expanded as needed, suitable for various scale and demand of power generation systems.

[0033] For example, the support device 300 can include structural members such as columns, beams, purlins, etc. to provide a stable support platform for the photovoltaic device 100, so that the photovoltaic device 100 can be installed on a roof, other locations of a house except the roof, or other carriers. In some embodiments of the present application, the photovoltaic system 1000 includes a photovoltaic roof, in which case the support device 300 can be a purlin arranged on the roof, and the photovoltaic device 100 can be installed on the roof through the support device 300.

[0034] In some embodiments, the photovoltaic device 100 can be mounted on the support device 300 in a detachable manner, so that the photovoltaic device 100 can be detached from the support device 300 when maintenance or replacement is needed. The detachable manner includes, but is not limited to, bolt connection and buckle connection. In other embodiments, the photovoltaic device 100 can be mounted on the support device 300 in a non-detachable manner, so that the connection strength between the photovoltaic device 100 and the support device 300 can be improved, the ability of the photovoltaic system 1000 to resist external environmental factors can be improved, and the stability and reliability of the photovoltaic system 1000 can be ensured. The non-detachable manner includes, but is not limited to, bonding or welding.

[0035] Further, in some embodiments, the photovoltaic system 1000 further includes an energy storage device, which is 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 household appliances, portable devices and other loads. The energy storage device and the photovoltaic device 100 can be electrically connected through a cable, or can be electrically connected through an intermediate device such as a junction box or a busbar. 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 battery, and can also be a super capacitor or other device capable of storing and releasing electrical energy.

[0036] In the present embodiment, the photovoltaic system 1000 includes the photovoltaic device 100, and it can be understood that the photovoltaic system 1000 at least includes the same beneficial effects as the photovoltaic device 100. Therefore, the beneficial effects of the photovoltaic system 1000 are described below in the beneficial effects of the photovoltaic device 100.

[0037] Please refer to Figure 1 The photovoltaic device 100 of the present embodiment includes the photovoltaic assembly 10.

[0038] Further, in some embodiments, the photovoltaic assembly 10 includes at least two photovoltaic assemblies 10, and the at least two photovoltaic assemblies 10 are overlapped with each other. Specifically, the at least two photovoltaic assemblies 10 can be overlapped in a specific direction to form an overall module (i.e. the photovoltaic device 100), and then the overall module is mounted on the roof or other carrier through the support device 300, so that the installation efficiency can be effectively improved, and the maximum power generation can be ensured. Moreover, the at least two photovoltaic assemblies 10 are first formed into an overall module, and then the overall module is mounted on the roof through the support device 300, so that the high-altitude operation on the roof can be reduced, and the safety can be improved.

[0039] The at least two photovoltaic components 10 are connected to each other in an overlapping manner, so that the connection between the adjacent two photovoltaic components 10 is more convenient, and the photovoltaic components 10 can be conveniently installed and disassembled, so that the work can be completed more quickly and efficiently during installation and maintenance, and the work efficiency is improved. In addition, the at least two photovoltaic components 10 can be connected by fasteners (such as bolts) while overlapping, so that the photovoltaic device 100 after assembly is more stable, and the stability and reliability of the photovoltaic device 100 are improved.

[0040] It should be noted that in some embodiments, the shapes and sizes of the at least two photovoltaic components 10 can be the same or different. Among them, the user can select photovoltaic components 10 with appropriate shapes and sizes according to specific use requirements. For example, in order to adapt to the size of the carrier, the user can select at least two photovoltaic components 10 with different sizes.

[0041] Among them, since the photovoltaic device 100 in the embodiment includes the photovoltaic component 10, it can be understood that the photovoltaic device 100 at least includes the same beneficial effects as the photovoltaic component 10, therefore, the beneficial effects of the photovoltaic device 100 please refer to the beneficial effects of the photovoltaic component 10 introduced below.

[0042] Please refer to Figures 1 to 3 The photovoltaic component 10 of the embodiment of the application includes a photovoltaic piece 11 and a mounting piece 13, the mounting piece 13 includes a loading part 131 and two guide parts 133, the shape of the loading part 131 matches the shape of the photovoltaic piece 11, and the loading part 131 is used to load the photovoltaic piece 11, the two guide parts 133 are respectively connected to the opposite ends of the loading part 131 in the first direction X, and are both bent away from the photovoltaic piece 11 relative to the loading part 131, and the guide part 133 is configured to be connected with an external carrier.

[0043] It can be understood that the photovoltaic piece 11 can be a single crystal silicon, a polycrystalline silicon or a thin film solar cell and other different types of solar energy conversion devices. Among them, the user can select photovoltaic pieces 11 with different efficiencies and sizes according to use requirements and environmental conditions and other factors. In some embodiments of the application, the shape of the photovoltaic piece 11 can be a planar structure or a curved surface structure to adapt to different use requirements of the user, realize better use of solar energy, and improve the power generation efficiency of the photovoltaic component 10.

[0044] The mounting member 13 is a structure in the photovoltaic module 10 for mounting and supporting structures such as the photovoltaic member 11. In some embodiments of the present application, the mounting member 13 comprises a loading portion 131 for loading the photovoltaic member 11 and two guide portions 133 configured to be connected with an external carrier (for example, the support device 300 described above), that is, the photovoltaic member 11 can be connected with the support device 300 through the guide portions 133 of the mounting member 13. It should be noted that in some embodiments, the loading portion 131 and the guide portion 133 can be an integral structure or a split structure, which is not limited in the present application.

[0045] The shape of the loading portion 131 matches the shape of the photovoltaic member 11, for example, in the case of a planar structure of the photovoltaic member 11, the loading portion 131 is also a planar structure, and the shape of the loading portion 131 is the same as that of the photovoltaic member 11. On the one hand, this can make the photovoltaic member 11 and the loading portion 131 closely connected, reduce the risk of looseness or displacement, and ensure the normal work of the photovoltaic module 10. On the other hand, it can facilitate the positioning and installation of the photovoltaic member 11 on the mounting member 13, and improve the assembly efficiency.

[0046] In some embodiments, the mounting member 13 can be made of metal and / or non-metal materials, and the metal materials include but are not limited to aluminum, iron, steel, or aluminum alloy, etc., and the non-metal materials include but are not limited to plastic, etc. For example, the mounting member 13 can be made of metal materials, for example, the mounting member 13 can be made of aluminum alloy, so as to improve the structural strength of the mounting member 13, enhance the ability of the mounting member 13 to resist the external environment, and ensure the stability and reliability of the work of the photovoltaic module 10.

[0047] In some embodiments, the loading portion 131 and the guide portion 133 are made of the same material. For example, in the case of the loading portion 131 made of aluminum alloy, the guide portion 133 is also made of aluminum alloy, so as to facilitate the production and processing of the mounting member 13.

[0048] In other embodiments, the loading portion 131 and the guide portion 133 are made of different materials. For example, the loading portion 131 can be made of materials with better heat insulation performance, such as glass wool, aerogel, etc., so as to reduce the heat conduction from the support device 300 or other carriers to the photovoltaic member 11 through the loading portion 131, prevent the temperature of the photovoltaic member 11 from being too high, and ensure the power generation efficiency of the photovoltaic member 11. The guide portion 133 can be made of metal with high structural strength, such as stainless steel, etc., so as to improve the anti-deformation ability of the mounting member 13 and ensure the stability and reliability of the work of the photovoltaic module 10.

[0049] In the photovoltaic module 10 of the embodiments of the present application, the mounting member 13 comprises a loading portion 131 and two guide portions 133, the loading portion 131 is capable of loading the photovoltaic member 11, and the guide portions 133 are capable of being connected with an external carrier. In other words, the photovoltaic member 11 can be mounted on the external carrier through the mounting member 13, that is, the photovoltaic member 11 is provided with a mounting structure, and has a good anti-deformation capability, so that the photovoltaic member 11 can be easily mounted on the carrier, the installation difficulty of the photovoltaic member 11 is reduced, and the installation efficiency is improved.

[0050] In addition, since the two guide portions 133 are both bent away from the loading portion 131 and the photovoltaic member 11, the loading portion 131 and the two guide portions 133 can jointly form a space (i.e., the mounting space 130 described below), so that compared with the case that the photovoltaic member 11 is directly laid on the external carrier, when the photovoltaic member 11 is arranged on the external carrier through the mounting member 13, the space jointly formed by the loading portion 131 and the two guide portions 133 can be used for air circulation, so that the heat dissipation effect of the photovoltaic module 10 is improved, the possibility of the photovoltaic member 11 being too high in temperature is reduced, and then on the one hand, the working stability of the photovoltaic member 11 is ensured, and the power generation efficiency of the photovoltaic member 11 is improved; on the other hand, the photovoltaic member 11 can be prevented from being damaged due to overheating, and the service life of the photovoltaic member 11 is prolonged.

[0051] The photovoltaic module 10 will be further described below in combination with the accompanying drawings.

[0052] Please refer to Figures 1 to 3 In some embodiments, the guide portion 133 is configured to participate in forming a guide groove 1330 for guiding 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 a square, a trapezoidal, a semicircular, and the like. The guide groove 1330 can be an open groove, and the opening of the guide groove 1330 is in communication with the outside, so that the guide groove 1330 can guide the fluid falling on the photovoltaic module 10, and prevent the fluid from accumulating on the photovoltaic module 10.

[0053] The guide groove 1330 can guide the rainwater, snow water or cleaning liquid on the photovoltaic module 10, so that the fluid can quickly flow down from the photovoltaic module 10, and prevent the fluid from accumulating on the photovoltaic module 10, so that on the one hand, the fluid can be prevented from soaking the photovoltaic member 11 and affecting the absorption of light by the photovoltaic member 11, so that the power generation efficiency of the photovoltaic module 10 can be ensured; on the other hand, the fluid can be prevented from penetrating into the photovoltaic member 11, so that the possibility of damage to the photovoltaic member 11 is reduced, and the service life of the photovoltaic member 11 is prolonged.

[0054] Further, please refer to Figure 4In some embodiments, in the first direction X, the guide portions 133 of two adjacent mounting members 13 together form a guide groove 1330. That is, in the case that the at least two photovoltaic modules 10 are sequentially overlapped in the first direction X, the guide portions 133 of two adjacent mounting members 13 can together form a guide groove 1330, so that the two adjacent mounting members 13 can form a more compact whole structure through the guide groove 1330, thereby improving the wind resistance, shock resistance, and stability and reliability of the photovoltaic device 100.

[0055] Referring to Figure 2 and Figure 3 In some embodiments, the guide portion 133 includes a first sub-portion 1331 and a second sub-portion 1333. The first sub-portion 1331 extends from the loading portion 131 in a direction away from the photovoltaic member 11, and the second sub-portion 1333 extends from the first sub-portion 1331 in the first direction X in a direction away from the loading portion 131. It should be noted that in some embodiments, the first sub-portion 1331 and the second sub-portion 1333 are smoothly connected, thereby eliminating the gap between the first sub-portion 1331 and the second sub-portion 1333, making the inner wall surface of the guide groove 1330 more continuous and smooth, reducing the accumulation of dust, dirt, and liquid at the connection between the first sub-portion 1331 and the second sub-portion 1333, and facilitating cleaning, thereby reducing the difficulty of cleaning.

[0056] Specifically, in some embodiments, in the first direction X, two adjacent guide portions 133 can be sequentially overlapped through the second sub-portion 1333, so that the at least two photovoltaic modules 10 are sequentially overlapped in the first direction X to form a whole structure. In the first direction X, the second sub-portion 1333 of one guide portion 133 and the second sub-portion 1333 of the adjacent other guide portion 133 are arranged in layers, and at this time, the first sub-portion 1331 and the second sub-portion 1333 of one guide portion 133 and the first sub-portion 1331 and the second sub-portion 1333 of the adjacent other guide portion 133 can together form a guide groove 1330. It can be understood that the mounting member 13 can be connected to the support device 300 (shown in the drawings) or other carriers through the second sub-portion 1333 of the guide portion 133. Figure 1

[0057] ​Further, in some embodiments, when the second sub-section 1333 of the two adjacent guide portions 133 are sequentially overlapped along the first direction X, a sealing member can be arranged between the second sub-section 1333 of the two adjacent guide portions 133, which is used to seal the gap between the second sub-section 1333 of the two adjacent guide portions 133, so as to prevent the fluid in the guide groove 1330 from leaking, and ensure the fluid guiding effect of the guide groove 1330. For example, please refer to Figure 1 In the case that the photovoltaic system 1000 comprises a photovoltaic roof, the arrangement of the sealing member can prevent the fluid in the guide groove 1330 from leaking into the house, thereby improving the user experience.

[0058] Please refer to Figure 1 , Figure 2 and Figure 4 In some embodiments, the mounting member 13 comprises a first section 135 and a second section 137, the first section 135 is used to load the photovoltaic member 11, and the second section 137 is connected to one end of the first section 135 in the second direction Y, which is perpendicular to the first direction X. It can be understood that, in some embodiments, the second direction Y and the first direction X can be the length direction and the width direction of the photovoltaic assembly 10, respectively.

[0059] Specifically, please refer to Figure 3 In some embodiments, in the third direction Z (a direction perpendicular to the first direction X and the second direction Y), the mounting member 13 comprises opposite first and second sides 138 and 139, and the photovoltaic member 11 is arranged on the first side 138 of the mounting member 13. Wherein, in the second direction Y, one mounting member 13 can be overlapped with the second section 137 of the adjacent mounting member 13, at this time, the second side 139 of the one mounting member 13 is connected to the region of the first side 138 of the adjacent mounting member 13 corresponding to the second section 137, that is, the second section 137 can be used to connect two adjacent photovoltaic assemblies 10 in the second direction Y, so as to make the at least two photovoltaic assemblies 10 overlapped in sequence along the second direction Y to form an integral module.

[0060] For example, in the case that the photovoltaic assembly 10 comprises a plurality of photovoltaic assemblies 10, the plurality of photovoltaic assemblies 10 can be overlapped in sequence along the second direction Y through the second section 137 of the mounting member 13 of each photovoltaic assembly 10 to form at least two integral modules (hereinafter referred to as first integral modules); then, the at least two first integral modules can be overlapped in sequence along the first direction X through the guide portion 133 of the mounting member 13 of each photovoltaic assembly 10 to finally form the photovoltaic device 100; or,

[0061] Please refer to Figure 4In the case where the photovoltaic assembly 10 comprises a plurality of photovoltaic assemblies 10, the plurality of photovoltaic assemblies 10 can be sequentially overlapped along the first direction X by the guide portion 133 of the respective mounting member 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 second direction Y by the second region 137 of the mounting member 13 of each photovoltaic assembly 10 to finally form the photovoltaic device 100.

[0062] It can be understood that the two adjacent photovoltaic assemblies 10 connected together in an overlapping manner can facilitate the installation and disassembly of the photovoltaic assembly 10, so that the installation and maintenance work can be completed more quickly and efficiently during the installation and maintenance process, thereby improving work efficiency. In addition, the two adjacent photovoltaic assemblies 10 can also be connected by fasteners (such as bolts, etc.), so as to improve the connection strength between the photovoltaic assemblies 10 and improve the stability of the photovoltaic device 100.

[0063] Please refer to Figure 1 and Figure 4 In some embodiments, the photovoltaic assembly 10 comprises a plurality of photovoltaic assemblies 10, which comprise a first photovoltaic assembly 101 and a second photovoltaic assembly 103, and the second photovoltaic assembly 103 is overlapped on the first photovoltaic assembly 101 in the second direction Y. That is, the second side 139 of the mounting member 13 of the second photovoltaic assembly 103 is connected with the first side 138 of the mounting member 13 of the first photovoltaic assembly 101. It should be noted that in some embodiments, the center of gravity of the second photovoltaic assembly 103 is higher than the center of gravity of the first photovoltaic assembly 101 in the direction of gravity. That is, the second photovoltaic assembly 103 is Figure 1 the photovoltaic assembly 10 located at the uppermost end of the photovoltaic device 100 in the

[0064] Specifically, in some embodiments, the mounting member 13 (hereinafter referred to as the first mounting member) of the first photovoltaic assembly 101 comprises a first region 135 and a second region 137, the first region 135 of the first mounting member is used to carry the photovoltaic member 11, and the second region 137 of the first mounting member is not used to carry the photovoltaic member 11; the mounting member 13 (hereinafter referred to as the second mounting member) of the second photovoltaic assembly 103 comprises a first region 135 and two second regions 137, and the first region 135 and the second region 137 of the second mounting member are both used to carry the photovoltaic member 11. Thus, in the case where the first photovoltaic assembly 101 and the second photovoltaic assembly 103 are sequentially overlapped in the second direction Y, the photovoltaic member 11 of the first photovoltaic assembly 101 and the photovoltaic member 11 of the second photovoltaic assembly 103 can be connected into one whole, in which case the user cannot see the mounting member 13 through the gap between the photovoltaic member 11 of the first photovoltaic assembly 101 and the photovoltaic member 11 of the second photovoltaic assembly 103, thereby on the one hand, the visual defects can be reduced and the aesthetics of the photovoltaic device 100 can be improved; on the other hand, the size of the photovoltaic member 11 can be increased and the power generation efficiency of the photovoltaic device 100 can be improved.

[0065] Further, 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, and the light-receiving surfaces of the photovoltaic members 11 of two adjacent photovoltaic assemblies 10 are flush in the case that the two photovoltaic assemblies 10 are sequentially overlapped in the second direction Y. It should be noted that the light-receiving surface of the photovoltaic member 11 is the portion of the photovoltaic member 11 that faces the sun and is used to absorb sunlight to convert it into electrical energy.

[0066] It can be understood that in the case that the first photovoltaic assembly 101 includes at least two, the at least two first photovoltaic assemblies 101 can be sequentially overlapped through the second region 137, i.e., the mounting member 13 of a first photovoltaic assembly 101 can be overlapped with the second region 137 of the mounting member 13 of an adjacent another first photovoltaic assembly 101. In this case, the light-receiving surfaces of the two adjacent first photovoltaic assemblies 101 are flush.

[0067] In some embodiments, the size of the first region 135 is greater than the size of the second region 137. It can be understood that in some embodiments of the present application, the size of the loading portion 131 in the first region 135 is the same as the size of the photovoltaic member 11. Thus, the size of the first region 135 being greater than the size of the second region 137 can ensure that the size of the photovoltaic member 11 is large, thereby increasing the power generation of the photovoltaic assembly 10 and increasing the amount of electricity generated.

[0068] Please refer to Figure 2 and Figure 3 In some embodiments, the loading portion 131 and the guide portion 133 jointly form a mounting space 130.
