In the related art, photovoltaic devices can be installed on roofs or other carriers and used to convert solar energy into electrical energy to achieve energy saving, environmental protection and other purposes. Generally, a photovoltaic system, such as a photovoltaic house, includes a photovoltaic assembly, and the photovoltaic assembly includes photovoltaic devices that can be directly laid on the surface of the carrier, that is, the photovoltaic devices are attached to the surface of the carrier, resulting in poor heat dissipation effect of the photovoltaic devices, which can easily affect the photoelectric conversion efficiency of the photovoltaic devices. Please refer to Figure 1 To solve the above problems, the embodiments of the present application provide a photovoltaic assembly 10, a photovoltaic device 100 and a photovoltaic system 1000.

[0034] 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 house, a photovoltaic carport, a ground power station, and a water surface photovoltaic system, etc.

[0035] 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, which ensures that the photovoltaic device 100 can receive light at a better angle and position, and at the same time can 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 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 rooftops, 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.

[0036] For example, the support device 300 can include a column, a beam, a purlin, or the like, 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.

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, and can also be a super capacitor or other devices capable of storing and releasing electric energy.

[0039] 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.

[0040] Please refer to Figure 1 and Figure 2 , the photovoltaic device 100 of the present embodiment includes the photovoltaic assembly 10.

[0041] Further, in some embodiments, the photovoltaic assembly 10 comprises at least two photovoltaic assemblies 10 which are connected to each other. Specifically, the at least two photovoltaic assemblies 10 can be connected together in a specific direction in a manner of overlapping or splicing, etc. to form an integral module (i.e. the photovoltaic device 100). In the case that the photovoltaic system 1000 comprises a photovoltaic house, the user can install the integral module on the roof or other carrier through the support device 300, so as to effectively improve the installation efficiency and also to ensure the maximization of the power generation. Moreover, the at least two photovoltaic assemblies 10 are first formed into an integral module, and then the integral module is installed on the roof through the support device 300, so as to reduce the high-altitude operation on the roof and improve the safety.

[0042] For example, the at least two photovoltaic assemblies 10 are connected to each other in a manner of overlapping, so as to make the connection between the adjacent two photovoltaic assemblies 10 more rapid and convenient, and to facilitate the installation and disassembly of the photovoltaic assembly 10, so that the work can be completed more rapidly and efficiently during the installation and maintenance, and the work efficiency is improved. In addition, the at least two photovoltaic assemblies 10 can be connected through fasteners (such as bolts, etc.) while overlapping, so as to make the photovoltaic device 100 after assembly more stable, and to improve the stability and reliability of the photovoltaic device 100.

[0043] It should be noted that in some embodiments, the shapes and sizes of the at least two photovoltaic assemblies 10 can be the same or different. The user can select the photovoltaic assembly 10 with appropriate shape and size according to the specific use requirements. For example, in order to adapt to the size of the carrier, the user can select at least two photovoltaic assemblies 10 with different sizes.

[0044] It should be noted that in some embodiments, the shapes and sizes of the at least two photovoltaic assemblies 10 can be the same or different. The user can select the photovoltaic assembly 10 with appropriate shape and size according to the specific use requirements. For example, in order to adapt to the size of the carrier, the user can select at least two photovoltaic assemblies 10 with different sizes.

[0045] It should be noted that in some embodiments, the shapes and sizes of the at least two photovoltaic assemblies 10 can be the same or different. The user can select the photovoltaic assembly 10 with appropriate shape and size according to the specific use requirements. For example, in order to adapt to the size of the carrier, the user can select at least two photovoltaic assemblies 10 with different sizes. Figure 1 Figure 2 The photovoltaic assembly 10 of the present embodiment comprises a photovoltaic piece 11 and a support piece 13, the support piece 13 comprises a body part 131 and support parts 133 arranged at opposite ends of the body part 131 in the first direction X, the support parts 133 protrude from the body part 131, and the two support parts 133 are arranged in a spaced manner along the first direction X and are used for supporting the photovoltaic piece 11 together, and the support parts 133 are configured to be connected with an external carrier.

[0046] ​It can be understood that the photovoltaic piece 11 is a structural member in the photovoltaic module 10 for converting light energy into electrical energy. The photovoltaic piece 11 can be a single-crystal silicon, a polycrystalline silicon, or a thin-film solar cell, etc. Different types of solar conversion devices. Among them, users can select photovoltaic pieces 11 of different efficiencies and sizes according to use requirements and environmental conditions and other factors. For example, the shape of the photovoltaic piece 11 can be a planar structure or a curved surface structure to meet different use requirements of users, better utilize solar energy, and improve the power generation efficiency of the photovoltaic module 10.

[0047] Specifically, in some embodiments, the photovoltaic piece 11 includes opposite light-receiving surfaces and back surfaces. The light-receiving surface is the surface of the photovoltaic piece 11 that directly faces the sun, receives sunlight, and completes photoelectric conversion. The back surface is the surface of the photovoltaic piece 11 opposite the sun. Among them, the photovoltaic piece 11 can only have a light-receiving surface to receive sunlight and convert sunlight into electrical energy for power generation; or, the light-receiving surface and the back surface of the photovoltaic piece 11 can both receive sunlight and convert sunlight into electrical energy for power generation (such as the back surface can receive reflected light). In some embodiments of the present application, the back surface of the photovoltaic piece 11 is opposite the support 13.

[0048] The support 13 is a structural member in the photovoltaic module 10 for supporting devices such as the photovoltaic piece 11. Please refer to the above description of the photovoltaic piece 11 for details. Figure 3 In some embodiments of the present application, the body portion 131 includes opposite first and second sides 1311 and 1313, and the first side 1311 is opposite the photovoltaic piece 11. The support portion 133 protrudes from the body portion 131, that is, in the direction from the first side 1311 to the second side 1313, one end of the support portion 133 is connected to the body portion 131, and the other end of the support portion 133 is higher than the first side 1311 of the body portion 131. In this way, the support portion 133 can support the photovoltaic piece 11 to space the photovoltaic piece 11 from the external carrier (such as the support device 300 described above). In addition, the two support portions 133 can be supported on opposite sides of the photovoltaic piece 11 in the first direction X, so that the photovoltaic piece 11 is more stable on the support 13, thereby improving the stability and reliability of the photovoltaic module 10. It should be noted that in some embodiments, the body portion 131 and the support portion 133 can be an integral structure or a separate structure, which is not limited by the present application.

[0049] Among them, the shape of the side of the support portion 133 connected to the photovoltaic piece 11 is adapted to the shape of the photovoltaic piece 11. For example, in the case of a planar structure of the photovoltaic piece 11, the side of the support portion 133 connected to the photovoltaic piece 11 is also a planar structure. In this way, the photovoltaic piece 11 and the support portion 133 can be closely matched to reduce the risk of loosening or displacement and ensure the normal operation of the photovoltaic module 10.

[0050] In some embodiments, the support 13 can be made of metal and / or non-metal materials. The metal materials can include, but are not limited to, aluminum, iron, steel, or aluminum alloy, etc. The non-metal materials can include, but are not limited to, plastic, etc. For example, the support 13 can be made of metal materials, such as aluminum alloy, so as to improve the structural strength of the support 13, enhance the ability of the support 13 to resist external environment, and ensure the stability and reliability of the photovoltaic module 10.

[0051] In some embodiments, the body part 131 and the support part 133 are made of the same material. For example, when the body part 131 is made of aluminum alloy, the support part 133 is also made of aluminum alloy, so as to facilitate the production and processing of the support 13.

[0052] In some other embodiments, the body part 131 and the support part 133 are made of different materials. For example, the body part 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 component 11 through the body part 131, prevent the temperature of the photovoltaic component 11 from being too high, and ensure the power generation efficiency of the photovoltaic component 11. The support part 133 can be made of metals with higher structural strength, such as stainless steel, etc., so as to improve the anti-deformation ability of the support part 133, ensure the support effect of the support part 133 on the photovoltaic component 11, and improve the stability and reliability of the photovoltaic module 10.

[0053] It can be understood that, in some embodiments of the present application, the photovoltaic component 11, the body part 131, and the two support parts 133 together form the heat dissipation space 101. That is, when the photovoltaic component 11 is connected with the two support parts 133, the photovoltaic component 11, the body part 131, and the two support parts 133 can together form the heat dissipation space 101, and the heat dissipation space 101 can be in communication with the external air. Therefore, compared with the photovoltaic component 11 directly laid on the external carrier, the arrangement of the heat dissipation space 101 can increase the air flow, improve the heat dissipation effect, reduce the working temperature of the photovoltaic component 11, and ensure the photoelectric conversion efficiency of the photovoltaic component 11.

[0054] In some embodiments, the two support parts 133 can be respectively arranged at opposite ends of the body part 131 in the first direction X. In the first direction X, the support parts 133 of the adjacent two supports 13 overlap with each other. In this way, on the one hand, the adjacent two supports 13 can form a more compact overall structure through the support parts 133, so as to improve the wind resistance and shock resistance of the photovoltaic module 10, and improve the stability and reliability of the photovoltaic device 100. On the other hand, the arrangement can make the alignment and connection of the adjacent two supports 13 more convenient, and improve the assembly efficiency. On the other hand, the superposition of the two support parts 133 can improve the anti-deformation ability of the support part 133, and improve the protection effect.

[0055] In the photovoltaic module 10 of the embodiments of the present application, the support 13 comprises a body portion 131 and two support portions 133, the two support portions 133 are arranged at intervals along the first direction X and are used together to support the photovoltaic component 11, and the support portion 133 is configured to be connected with the external carrier, so that the photovoltaic component 11 can be spaced from the external carrier. Compared with the photovoltaic component 11 directly laid on the surface of the external carrier, the heat dissipation effect of the photovoltaic component 11 is better, so as to improve the photoelectric conversion efficiency of the photovoltaic component 11.

[0056] In addition, the support 13 comprises a body portion 131 and two support portions 133, the two support portions 133 are used together to support the photovoltaic component 11, and the support portion 133 is configured to be connected with the external carrier, in other words, the photovoltaic component 11 can be installed on the external carrier through the support 13, that is, the photovoltaic component 11 has a mounting structure, and has good anti-deformation ability. It can avoid the difficulty of installing the photovoltaic component 11 on the carrier due to the easy deformation of the photovoltaic component 11, reduce the installation difficulty of the photovoltaic component 11, and improve the installation efficiency.

[0057] The photovoltaic module 10 will be further described below in combination with the drawings.

[0058] Please refer to Figure 2 In some embodiments, the support portion 133 is a multi-segment bending structure. It can be understood that the multi-segment bending structure is a structure composed of at least two bending segments, and each bending segment is connected by a certain angle or curvature. That is, the support portion 133 is a structure composed of at least two bending segments, which can improve the adaptability of the support 13 and ensure the normal assembly of the support 13 in different installation scenarios.

[0059] Among them, the support portion 133 is a multi-segment bending structure, which can reduce the weight of the support portion 133 and facilitate the lightness of the support 13, thereby on the one hand, it can reduce the difficulty of carrying and facilitate installation; on the other hand, it can reduce the load of the external carrier and improve the stability and reliability of the photovoltaic system 1000.

[0060] In other embodiments, the support portion 133 is a solid structure, that is, the support portion 133 can be a solid block structure, and the support portion 133 can be arranged on the first side 1311 of the body portion 131, so that the structural strength of the support portion 133 is higher, the anti-deformation ability of the support portion 133 is improved, and the stability of the support portion 133 supporting the photovoltaic component 11 is ensured.

[0061] In some embodiments, the support portion 133 is a hollow structure, i.e., the support portion 133 can be a hollow block structure, and the support portion 133 can be arranged on the first side 1311 of the body portion 131, thereby reducing the weight of the support portion 133 and facilitating the lightening of the support 13, so as to reduce the difficulty of carrying and facilitate installation on the one hand, and reduce the external carrier load and improve the stability and reliability of the photovoltaic system 1000 on the other hand.

[0062] For the convenience of understanding, the support portion 133 is taken as an example of a multi-segment bending structure in the following embodiments.

[0063] For the convenience of understanding, the support portion 133 is taken as an example of a multi-segment bending structure in the following embodiments. Figure 2 Figure 3 In some embodiments, the support portion 133 is a multi-segment bending structure. The support portion 133 includes a first segment 1331, a second segment 1333, a third segment 1335, and a fourth segment 1337. The first segment 1331 extends from the body portion 131 towards the photovoltaic component 11. The second segment 1333 extends from the first segment 1331 in the first direction X away from the body portion 131. The third segment 1335 extends from the second segment 1333 away from the photovoltaic component 11. The fourth segment 1337 extends from the third segment 1335 in the first direction X away from the body portion 131.

[0064] Specifically, in some embodiments, the first segment 1331 extends from one end of the body portion 131 in the first direction X towards the photovoltaic component 11. The second segment 1333 extends from the end of the first segment 1331 away from the body portion 131 in the first direction X away from the body portion 131. The third segment 1335 extends from the end of the second segment 1333 away from the first segment 1331 away from the photovoltaic component 11. The fourth segment 1337 extends from the end of the third segment 1335 away from the second segment 1333 in the first direction X away from the body portion 131. The second segment 1333 can be used to support the photovoltaic component 11. In the first direction X, the fourth segments 1337 of two adjacent support portions 133 can be overlapped, i.e., the fourth segments 1337 of two adjacent support portions 133 are arranged in layers, so that at least two photovoltaic assemblies 10 are overlapped in the first direction X to form an integral structure. It can be understood that the support 13 can be connected with the support device 300 or other external carriers through the fourth segments 1337 of the support portions 133.

[0065] ​In addition, the first section 1331, the second section 1333 and the third section 1335 can jointly form a groove, and the groove can be in communication with the external air. Thus, the groove can increase air flow, improve heat dissipation effect, reduce the working temperature of the photovoltaic component 11, and ensure the photoelectric conversion efficiency of the photovoltaic component 11. It should be noted that, in some embodiments, the cross-sectional shape of the groove includes but is not limited to a square, a trapezoid, a semicircle, a U shape, and the like.

[0066] In some embodiments, the support part 133 is configured to participate in forming a guide groove 130 for guiding fluid flow. It should be noted that, in some embodiments, the cross-sectional shape of the guide groove 130 includes but is not limited to a V shape, a U shape, a square, a trapezoid, a semicircle, and the like. The guide groove 130 can be an open groove, and the opening of the guide groove 130 is in communication with the external environment. Thus, the guide groove 130 can guide the fluid falling on the photovoltaic module 10, and reduce or even avoid the accumulation of the fluid on the photovoltaic module 10.

[0067] Specifically, in some embodiments, when the two adjacent photovoltaic modules 10 are overlapped along the first direction X, the third section 1335 and the fourth section 1337 of the two adjacent support parts 133 can jointly form the guide groove 130. The guide groove 130 can guide the rain, snow 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. Thus, on the one hand, the fluid can avoid soaking the photovoltaic component 11, so as to ensure the light absorption capacity of the photovoltaic component 11, and thus ensure the power generation efficiency of the photovoltaic module 10. On the other hand, the fluid can prevent from penetrating into the photovoltaic component 11, so as to reduce the possibility of damaging the photovoltaic component 11, and prolong the service life of the photovoltaic component 11.

[0068] It should be noted that, in some embodiments, the third section 1335 and the fourth section 1337 are smoothly connected, so that the gap between the third section 1335 and the fourth section 1337 can be eliminated, the inner wall of the guide groove 130 is more continuous and smooth, the accumulation of dust, dirt and liquid at the connection between the third section 1335 and the fourth section 1337 can be reduced, and the cleaning difficulty can be reduced.

[0069] In some embodiments, when the fourth sections 1337 of the two adjacent support parts 133 are overlapped along the first direction X, a sealing member can be arranged between the fourth sections 1337 of the two adjacent support parts 133, and the sealing member can seal the gap between the fourth sections 1337 of the two adjacent support parts 133. For example, when the photovoltaic system 1000 includes a photovoltaic house, the sealing member can prevent the liquid on the support part 133 from leaking into the photovoltaic house through the gap between the fourth sections 1337 of the two support parts 133, so as to improve the user experience.

[0070] In some embodiments, the photovoltaic device 11 is provided with a cell layer. Further, in some embodiments, the photovoltaic device 11 further comprises a first cover plate and a second cover plate, which are sequentially stacked in the direction from the light-receiving surface to the back surface, and the cell layer is connected between the first cover plate and the second cover plate.

[0071] The first cover plate and the second cover plate can collectively protect the cell layer and other internal components of the photovoltaic device 11 from physical impact and environmental erosion, thereby reducing the possibility of damage to the photovoltaic device 11. The cell layer, the first cover plate and the second cover plate can be connected together by a film to form a stable and firm structure, thereby improving the stability of the overall structure. It should be noted that, in some embodiments, the first cover plate and the second cover plate can be made of at least one of glass, PET, metal, composite fiber, etc.; and the film can be made of at least one of EVA, POE, PVB, etc.

[0072] Referring to Figure 2 and Figure 3 In some embodiments, the photovoltaic device 11 comprises a connecting region 111 and a loading region 113, and the connecting region 111 is used to connect with the support 13. The connecting region 111 can be connected with the support assembly by a connecting member (such as a bolt or an adhesive, etc.). Specifically, in some embodiments, the connecting region 111 comprises a corner of the photovoltaic device 11. In other embodiments, the connecting region 111 comprises regions on opposite sides of the photovoltaic device 11 in the first direction X.

[0073] In some embodiments, the cell layer is provided in the loading region 113. In this way, when the connecting region 111 is connected with the support 13 by a connecting member such as a bolt, the cell layer does not interfere with the connecting member, thereby ensuring the normal installation of the photovoltaic device 11 on the support 13.

[0074] In other embodiments, the cell layer is provided in the loading region 113 and the connecting region 111. In this way, the size of the cell layer can be increased, so that the photovoltaic device 11 can capture more sunlight and convert it into electrical energy, thereby improving the power generation efficiency of the photovoltaic device 11. It should be noted that, in this embodiment, the connecting member can be provided on the back surface of the photovoltaic device 11, so that the connecting region 111 is connected with the support 13 by the connecting member. Exemplarily, the connecting member includes, but is not limited to, a buckle, an adhesive, etc.

[0075] Referring to Figure 1 , Figure 2 , Figure 4 and Figure 5In some embodiments, the support 13 comprises a first region 135 for loading the photovoltaic member 11 and a second region 137 connected to one end of the first region 135 in a second direction Y perpendicular to the first direction X. It is understood that in some embodiments, the second region 137 is not used for loading the photovoltaic member 11. In other embodiments, the second region 137 is also used for loading the photovoltaic member 11, in which case both the first region 135 and the second region 137 are used for loading the photovoltaic member 11, so as to prevent the user from seeing the support 13, thereby improving the aesthetic appearance of the photovoltaic assembly 10.

[0076] Specifically, in some embodiments, in a direction perpendicular to both the first direction X and the second direction Y, the support 13 comprises a first side (including the first side 1311 of the body portion 131) and a second side (including the second side 1313 of the body portion 131) opposite to each other, and the photovoltaic member 11 is arranged on the first side of the support 13. In the second direction Y, one support 13 can be overlapped with the second region 137 of another adjacent support 13, in which case the second side of the one support 13 is connected to a region of the first side of the other adjacent support 13 corresponding to the second region 137. That is, the second region 137 can be used to connect two adjacent photovoltaic assemblies 10 in the second direction Y, so that at least two photovoltaic assemblies 10 can be overlapped in sequence in the second direction Y to form an integral module. It is understood that in this embodiment, the first region 135 is used for loading the photovoltaic member 11, and the second region 137 is not used for loading the photovoltaic member 11.

[0077] For example, referring to Figure 4 In the case where the photovoltaic assembly 10 comprises a plurality of photovoltaic assemblies 10, the plurality of photovoltaic assemblies 10 can be overlapped in sequence in the first direction X by the support portions 133 of the respective supports 13 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 in the second direction Y by the second regions 137 of the supports 13 of the respective photovoltaic assemblies 10 to finally form the photovoltaic device 100; or,

[0078] For example, referring to Figure 5 In the case where the photovoltaic assembly 10 comprises a plurality of photovoltaic assemblies 10, the plurality of photovoltaic assemblies 10 can be overlapped in sequence in the second direction Y by the second regions 137 of the respective supports 13 to form at least two integral modules (hereinafter referred to as second integral modules); then, the at least two second integral modules can be overlapped in sequence in the first direction X by the support portions 133 of the supports 13 of the respective photovoltaic assemblies 10 to finally form the photovoltaic device 100.

[0079] It can be understood that the two adjacent photovoltaic components 10 are connected together in a lap joint manner, which facilitates the installation and disassembly of the photovoltaic component 10, so that the installation and maintenance work can be completed more quickly and efficiently during the installation and maintenance process, thereby improving the work efficiency. In addition, the two adjacent photovoltaic components 10 can also be connected by fasteners (such as bolts, etc.), so as to improve the connection strength between the photovoltaic components 10 and improve the stability of the photovoltaic device 100.

[0080] In other embodiments, in the second direction Y, the plurality of photovoltaic components 10 can also be connected together in a splicing manner. It can be understood that in the present embodiment, the first area 135 and the second area 137 are both used to load the photovoltaic components 11.

[0081] Please refer to Figure 2 and Figure 3 In some embodiments, the photovoltaic component 10 further comprises a junction box 15, which is arranged in the heat dissipation space 101 and is electrically connected with the photovoltaic component 11.

[0082] It can be understood that the junction box 15 is an element in the photovoltaic component 10 for electrical connection. The junction box 15 can be electrically connected with the photovoltaic component 11 and the energy storage device to form a complete electrical circuit, so that the electrical energy generated by the photovoltaic component 11 can be transmitted to the energy storage device. The junction box 15 is arranged in the heat dissipation space 101, wherein the arrangement of the heat dissipation space 101 can provide protection for the junction box 15, reduce the possibility of impurities such as liquid or dust entering the junction box 15, avoid short circuit or corrosion, prolong the service life of the junction box 15, and ensure the stable operation of the photovoltaic component 10 in harsh environment. In addition, the arrangement of the junction box 15 in the heat dissipation space 101 can also be beneficial to the heat dissipation of the junction box 15, reduce the possibility of overheating damage of the junction box 15, and ensure the stability and reliability of the photovoltaic component 10. In addition, the arrangement of the junction box 15 in the heat dissipation space 101 can also prevent the user from seeing the junction box 15, thereby reducing the visual defects of the photovoltaic component 10 and improving the aesthetics.

[0083] In some embodiments, the photovoltaic component 10 further comprises an electrical connector 17 for electrically connecting the two adjacent junction boxes 15. Specifically, in the case where the photovoltaic component 10 comprises at least two, the junction boxes 15 of the at least two photovoltaic components 10 can be connected together in series or parallel by the electrical connection line, thereby facilitating the control of the charging or discharging functions of the photovoltaic device 100 (as shown in the figure) and improving the stability and reliability of the photovoltaic device 100.
