[0002] The photovoltaic system is a photovoltaic product capable of generating electricity by using solar energy, and also serving as sunshade, heat insulation and rain blocking. It can be applied to the outer periphery of outdoor public and large commercial facilities or the courtyard of private residences. The junction box is used to collect the electrical energy generated by the photovoltaic panel and transmit the electrical energy to external equipment through wires. In the prior art, the junction box is usually directly installed on the back or side of the photovoltaic panel, which is in a relatively exposed position, resulting in that the junction box is easily affected by external environmental factors, such as high temperature caused by direct sunlight and short circuit caused by rainwater contact, thereby reducing the service life and reliability of the junction box and affecting the overall aesthetics of the photovoltaic system.

[0034] Please refer to Figure 1The photovoltaic system 10000 is a photovoltaic product capable of generating electricity by using solar energy, and simultaneously serving as a sunshade, heat insulator, and rain blocker. The photovoltaic system 10000 can be applied to an outdoor public area, a periphery of a large commercial facility, or a private residence. For example, the photovoltaic system 10000 can be installed on a roof. The photovoltaic system 10000 is described herein by way of example as being installed on a roof. The photovoltaic system 10000 includes a support assembly 3000 and a photovoltaic assembly 1000, and the photovoltaic assembly 1000 is installed on the support assembly 3000.

[0035] The support assembly 3000 is a structure capable of providing installation and support for the photovoltaic assembly 1000 in the photovoltaic system 10000. The support assembly 3000 can be made of a metal material and / or a non-metal material. The metal material includes, but is not limited to, aluminum, iron, steel, or an aluminum alloy.

It should be noted that, in some embodiments, the overall shape of the support assembly 3000 can include, but is not limited to, a square, a cylinder, a rhombus, etc. In this way, the support assembly 3000 can be adapted to install photovoltaic assemblies 1000 of different sizes and shapes. For example, the support assembly 3000 can be a column, a beam, a purlin, etc. of a roof to provide a stable support platform for the photovoltaic assembly 1000. The photovoltaic assembly 1000 can be installed on the roof, other locations of a house except the roof, or other carriers, and the photovoltaic assembly 1000 can be directly or indirectly installed on the support assembly 3000 through a mounting member, etc.

[0036] Further, in some embodiments, the photovoltaic system 10000 further includes an energy storage device, which is electrically connected to the photovoltaic assembly 1000. The energy storage device can store the electrical energy generated by the photovoltaic assembly 1000 and can supply power to household appliances, portable devices, etc. Of course, the photovoltaic assembly 1000 can also directly supply power to household appliances, portable devices, etc. The energy storage device and the photovoltaic assembly 1000 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 not only a lithium ion battery, a lead-acid battery, or other types of rechargeable batteries, but also a super capacitor or other devices capable of storing and releasing electrical energy.

[0037] Please refer to Figure 2 or Figure 4 or Figure 5The photovoltaic assembly 1000 comprises a photovoltaic piece 100, which is a solar energy conversion device for converting solar energy into electric energy. The photovoltaic piece 100 can be a single-crystal silicon, a polycrystalline silicon, or a thin-film solar cell, etc. Different types of solar energy conversion devices can be selected according to the use requirements and the support assembly 3000. In the present application, the length direction of the photovoltaic piece 100 is the length direction X, the width direction of the photovoltaic piece 100 is the width direction Y, and the thickness direction of the photovoltaic piece 100 is the thickness direction Z. It should be noted that the thickness direction Z of the photovoltaic piece 100 is the thickness direction of the body part 11 of the photovoltaic piece 100.

[0038] The photovoltaic assembly 1000 comprises at least two photovoltaic pieces 100. Specifically, the at least two photovoltaic pieces 100 can be connected together in a specific direction by means of lapping or splicing, etc. to form an integral module (i.e. the photovoltaic assembly 1000). The photovoltaic assembly 1000 is arranged on the support assembly 3000, which can absorb sunlight, convert solar energy into electric energy for power generation, and cover the support assembly 3000, thereby reducing the sunlight from shining into the photovoltaic system 10000 and achieving a sun-shading effect. The photovoltaic system 10000 refers to the space below the photovoltaic assembly 1000 and surrounded by the support assembly 3000. In some embodiments, the photovoltaic assembly 1000 can be detachably connected to the support assembly 3000, so that the photovoltaic assembly 1000 can be easily detached from the support assembly 3000 when it needs to be repaired or replaced. The detachable connection mode includes, but is not limited to, bolt connection and buckle connection, etc. In other embodiments, the photovoltaic assembly 1000 can be non-detachably connected to the support assembly 3000, so as to improve the bonding strength between the photovoltaic assembly 1000 and the support assembly 3000, improve the ability of the photovoltaic system 10000 to resist external environmental factors, and ensure the stability and reliability of the photovoltaic system 10000. The non-detachable connection mode includes, but is not limited to, bonding or welding, etc.

[0039] For example, the at least two photovoltaic pieces 100 are connected to each other in a lap joint manner, so that the connection between the adjacent two photovoltaic pieces 100 is more convenient and fast, and the photovoltaic piece 100 can be conveniently installed and disassembled, so that the work can be more quickly and efficiently completed during installation and maintenance, and the work efficiency is improved. In addition, the at least two photovoltaic pieces 100 can be connected by using fasteners (such as bolts) while being lap jointed, so that the photovoltaic assembly 1000 after assembly is more stable, and the stability and reliability of the photovoltaic assembly 1000 are improved. It should be noted that in some embodiments, the shapes and sizes of the at least two photovoltaic pieces 100 can be the same or different. Among them, the user can select the photovoltaic piece 100 with appropriate shape and size according to the specific use requirement. For example, in order to adapt to the size of the carrier, the user can select at least two photovoltaic pieces 100 with different sizes.

[0040] In the embodiment, the photovoltaic assembly 1000 includes the photovoltaic piece 100, and can understand that the photovoltaic assembly 1000 at least includes the same beneficial effects as the photovoltaic piece 100, so the beneficial effects of the photovoltaic assembly 1000 are described below.

[0041] Please refer to Figure 1 , and Figure 2 and Figure 3 , or Figure 4 , or Figure 5 The photovoltaic piece 100 provided by the embodiment of the application includes a photovoltaic panel 10 and a junction box 30. The photovoltaic panel 10 includes a first bending part 12, a body part 11 and a second bending part 14, which are connected in sequence in the width direction Y, and the first bending part 12 and the second bending part 14 are respectively bent relative to the body part 11 and form a first accommodating space 301 and a second accommodating space 302 respectively. The junction box 30 is electrically connected with the photovoltaic panel 10, and the junction box 30 is arranged in the first accommodating space 301 and / or the second accommodating space 302.

[0042] Specifically, the photovoltaic panel 10 is an element in the photovoltaic component 100 that converts solar energy into electrical energy, and the conversion process can be direct conversion or indirect conversion. Direct conversion means that the photovoltaic panel 10 can directly convert solar energy into electrical energy, and indirect conversion means that the photovoltaic panel 10 can convert solar energy into chemical energy or other forms of energy before converting it into electrical energy. In the case of multiple photovoltaic components 100, the photovoltaic components 100 are arranged in sequence along the length direction X and / or the width direction Y to cover the roof. Among them, the photovoltaic components 100 arranged along the length direction X are sequentially overlapped. Overlapping means that two adjacent photovoltaic components 100 in the length direction X have a partial overlap in the length direction X, which can ensure the stability and continuity of the photovoltaic assembly 1000 in the overall structure, prevent gaps or misalignment between the photovoltaic components 100 due to external factors such as wind, vibration, etc., and thus improve the installation stability of the photovoltaic assembly 1000 in the length direction X.

[0043] The body part 11 is used to convert solar energy into electrical energy. The cross-sectional shape of the body part 11 in the XY plane can include but is not limited to regular shapes such as square, circle, triangle, and diamond, or irregular shapes. In the embodiments of the present application, only the cross-sectional shape of the photovoltaic panel 10 is taken as an example of a square. The joint in the body part 11 can transmit the converted electrical energy to the junction box 30, and the junction box 30 can transmit the electrical energy to external equipment, which can be an energy storage device capable of storing electrical energy.

[0044] The first bending part 12 is connected to one end of the body part 11 in the width direction Y and is bent relative to the body part 11 to form a first accommodation space 301. The junction box 30 can be installed in the first bending part 12 and accommodated in the first accommodation space 301. The first bending part 12 is connected to one end of the body part 11 in the length direction X, and the direction and angle of bending can be adjusted according to actual design requirements. The cross-sectional shape of the first bending part 12 cut by the YZ plane includes but is not limited to square, trapezoidal, semicircular, and U-shaped. There is a certain height difference and space interval between the first bending part 12 and the body part 11. After being installed on the support assembly 3000, the support assembly 3000 and the first bending part 12 have a first accommodation space 301. The photovoltaic panel 10 will absorb heat under solar radiation, and the temperature will rise. The first accommodation space 301 can act as a heat dissipation channel to dissipate part of the heat on the photovoltaic panel 10.

[0045] In some embodiments, the body portion 11 and the first bending portion 12 are integrated, i.e., the body portion 11 and the first bending portion 12 are one integral structure, thereby improving the bonding strength between the body portion 11 and the first bending portion 12, preventing the body portion 11 and the first bending portion 12 from being separated during the operation of the photovoltaic panel 10, and ensuring the stability and reliability of the photovoltaic panel 10. In other embodiments, the body portion 11 and the first bending portion 12 are separate, i.e., the body portion 11 and the first bending portion 12 are two different structures. In one example, the body portion 11 and the first bending portion 12 can be combined together by a detachable connection mode, including but not limited to a buckle connection or a threaded connection, etc. In another example, the body portion 11 and the first bending portion 12 can be combined together by a non-detachable connection mode, including but not limited to bonding or welding, etc.

[0046] The second bending portion 14 is connected to the other end of the body portion 11 in the width direction Y and is bent relative to the body portion 11 to form a second accommodating space 302. The junction box 30 can be mounted on the second bending portion 14 and accommodated in the second accommodating space 302. The second bending portion 14 is connected to one end of the body portion 11 in the length direction X, and the bending direction and angle can be adjusted according to actual design requirements. The cross-sectional shape of the second bending portion 14 cut by the YZ plane includes but is not limited to a square, a trapezoid, a semicircle, and a U shape, etc. There is a certain height difference and space interval between the second bending portion 14 and the body portion 11, and after being installed on the roof, the roof and the second bending portion 14 have the second accommodating space 302. The photovoltaic panel 10 will absorb heat under the sunlight and the temperature will rise, and the second accommodating space 302 can act as a heat dissipation channel to dissipate part of the heat on the photovoltaic panel 10. The shape, structure, material, etc. of the first bending portion 12 and the second bending portion 14 can be the same or different. Exemplarily, the first bending portion 12 and the second bending portion 14 of the present application are different structures and are connected to the two ends of the body portion 11 in the width direction Y, respectively. It can be understood that in the case that the first bending portion 12 and the second bending portion 14 are the same structure, the first bending portion 12 at least includes the beneficial effects of the second bending portion 14, and the second bending portion 14 at least includes the beneficial effects of the first bending portion 12.

[0047] A plurality of photovoltaic components 100 are connected to each other to form a photovoltaic assembly 1000. In the photovoltaic assembly 1000, at least two photovoltaic components 100 are sequentially overlapped in the width direction Y, and in the two adjacent photovoltaic panels 10 in the width direction Y, the first bending portion 12 of one photovoltaic panel 10 is overlapped with the second bending portion 14 of the other photovoltaic panel 10, or the second bending portion 14 of one photovoltaic panel 10 is overlapped with the first bending portion 12 of the other photovoltaic panel 10, thereby achieving the connection of a plurality of photovoltaic panels 10 in the width direction Y without using other connecting components, and achieving the installation of the photovoltaic panel 10 in a structure without purlin on the roof.

[0048] The junction box 30 is used to collect and transmit the electrical energy generated by the photovoltaic panel 10. The junction box 30 is provided with wires, terminals and the like, and can be connected to the cell layer 18 of the photovoltaic panel 10. In the photovoltaic assembly 1000, the junction boxes 30 of different photovoltaic panels 10 can be connected in series or parallel through electrical connecting components. The junction box 30 includes an integrated junction box 30 and a split junction box 30, and the junction box 30 of the present application adopts a split junction box 30. The split junction box 30 is composed of a plurality of split junction boxes 30, and can be two-split, three-split or other forms. The junction box 30 of the present application adopts a two-split junction box 30. The junction box 30 includes two split junction boxes 30, namely a first split 31 and a second split 32. Each split junction box 30 has a diode, and the positive and negative cables are distributed on different split junction boxes 30. The connection between the split junction box 30 and the photovoltaic panel 10 is achieved through the internal bus bar, and each split junction box 30 (the first split 31 and / or the second split 32) is connected to different areas of the photovoltaic panel 10, thereby dispersing the current, reducing the resistance and improving the output efficiency of the photovoltaic panel 10. In the connection relationship with other photovoltaic panels 10, the positive and negative junction boxes 30 (the first split 31 and the second split 32) of the split junction box 30 are installed on the two sides of the photovoltaic panel 10 in any direction, and are connected in series or parallel with other photovoltaic panels 10 through electrical connecting components (such as cables), which greatly shortens the mutual distance between the cell layer 18 in the photovoltaic panel 10 and the circuit connection of the cell layer 18 during installation, reduces the use and loss of cables, reduces the power loss caused by the length of the cable, and improves the power of the photovoltaic assembly 1000. In one installation mode, the first accommodating space 301 and the second accommodating space 302 are configured to accommodate the first split 31 and the second split 32, respectively. In another installation mode, the first accommodating space 301 is configured to accommodate the first split 31 and the second split 32. In still another installation mode, the second accommodating space 302 is configured to accommodate the first split 31 and the second split 32.

[0049] The first bending part 12 of one photovoltaic panel 10 can be overlapped with the second bending part 14 of another photovoltaic panel 10 among two photovoltaic panels 10 adjacent in the width direction Y. First, the connection of multiple photovoltaic panels 10 in the width direction Y can be completed by using the structure of the photovoltaic panel 10 itself without using other connecting components, thereby improving the installation efficiency of the photovoltaic panel 10. Second, the first accommodating space 301 and the second accommodating space 302 can provide partial protection for the junction box 30, and the photovoltaic panel 10 can shield the junction box 30 from sunlight and rainwater, thereby avoiding the junction box 30 from being irradiated by sunlight to cause the temperature to be too high or being in contact with rainwater to cause short circuit, thereby improving the service life of the junction box 30. Third, the first accommodating space 301 and the second accommodating space 302 are spaces occupied by the structure of the photovoltaic panel 10 itself, and the junction box 30 does not need to occupy additional space, thereby optimizing the layout of the photovoltaic component 100. Fourth, the junction box 30 is divided into the first part 31 and the second part 32, and the first part 31 and the second part 32 are connected to different areas (i.e., the first accommodating space 301 and the second accommodating space 302) of the photovoltaic panel 10, thereby shortening the mutual distance between the circuit of the photovoltaic panel 10 and the circuit connection of the first part 31 and the second part 32 during installation. This can not only disperse the current, reduce the amount of cable used, reduce cable loss, reduce resistance, and improve the output efficiency of the photovoltaic panel 10. Fifth, the first part 31 and the second part 32 generate less heat compared with the integrated junction box 30, thereby improving the heat dissipation effect of the photovoltaic component 100. Sixth, the first accommodating space 301 and the second accommodating space 302 can be used as wire arranging grooves of the junction box 30. The cables can be connected and transferred in the first accommodating space 301 and the second accommodating space 302. On the one hand, the cables are hidden, and the photovoltaic component 100 is kept beautiful. On the other hand, the cables are provided with directional guidance and fixed support, so that the cables can be regularly arranged along the preset path in the first accommodating space 301 and the second accommodating space 302, thereby ensuring smooth cable routing of the junction box 30 between adjacent photovoltaic components 100, and improving the neatness of cable wiring. The physical boundary (such as the inner wall of the second bending part 14 and the inner wall of the first bending part 12) of the first accommodating space 301 and the second accommodating space 302 can form a natural constraint on the cables of the junction box 30, thereby limiting the cables from shaking during installation or operation, and prolonging the service life of the cables.

[0050] Please refer to Figure 3 , or Figure 4 , or Figure 5 In some embodiments, the photovoltaic panel 10 includes a light-receiving surface 101 and a back surface 103 opposite to each other, and the body part 11 is provided with a cell layer 18. The first part 31 is installed on the back surface 103 of the first bending part 12 and / or the second bending part 14, and the second part 32 is installed on the back surface 103 of the first bending part 12 and / or the second bending part 14.

[0051] Specifically, in the thickness direction Z of the photovoltaic panel 10, the photovoltaic panel 10 includes a light-receiving surface 101 and a back surface 103 opposite to each other. The light-receiving surface 101 faces the external environment after the photovoltaic panel 10 is installed, can directly receive the irradiation of sunlight, and can perform photoelectric conversion. The back surface 103 faces away from the sunlight, and can avoid direct sunlight. The first sub-body 31 and / or the second sub-body 32 are installed on the back surface 103 of the first bending portion 12 and / or the second bending portion 14, which can avoid direct sunlight on the junction box 30, ensure that the first sub-body 31 and / or the second sub-body 32 maintain an appropriate temperature, and prolong the service life of the first sub-body 31 and / or the second sub-body 32. The cell layer 18 is composed of a plurality of cell units. When sunlight irradiates the cell layer 18, the photon energy causes the electrons in the cell units to jump, thereby generating direct current power. The generated power is transmitted to the first sub-body 31 and / or the second sub-body 32 through the joints inside the photovoltaic panel 10, the first sub-body 31 and / or the second sub-body 32 collect the power generated by the cell units, and the power is transmitted to the energy storage device or directly supplied to the load through the external electrical connector. Further, in some embodiments, the photovoltaic panel 10 further includes a first cover plate and a second cover plate, which are sequentially stacked in the direction from the light-receiving surface 101 to the back surface 103, and the cell layer 18 is connected between the first cover plate and the second cover plate. Among them, the first cover plate and the second cover plate can jointly protect the cell layer 18 and other internal elements of the photovoltaic panel 10, so as to avoid physical impact and environmental erosion from the outside world, and reduce the possibility of damage to the photovoltaic panel 10. The cell layer 18 and the first cover plate and the second cover plate can be connected together by a film, forming a stable and firm structure, and 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.; the film can be made of at least one of EVA, POE, PVB, etc.

[0052] Please refer to Figure 3 , or Figure 4 , or Figure 5 In some embodiments, in the width direction Y, the size L1 of the body portion 11 is greater than the size L2 of the first bending portion 12.

[0053] Specifically, in the width direction Y, the size L1 of the body portion 11 can be 1.2 times, 2.2 times, 3 times, 3.4 times, 4.2 times, 5.5 times, 5.8 times, 6.1 times, 7.2 times, 9.2 times, etc. of the size L2 of the first bending portion 12, which is not limited in the present application. If the size L1 of the body portion 11 is less than the size L2 of the first bending portion 12 in the width direction Y, the laying area of the battery layer 18 of the body portion 11 is insufficient, which reduces the photoelectric conversion efficiency of the photovoltaic device 100. Meanwhile, in the case where the photovoltaic device 100 is installed on the support assembly 3000, the body portion 11 is connected to or abuts against the support assembly 3000. If the size L1 of the body portion 11 is too small, the connecting area of the body portion 11 to the support assembly 3000 is insufficient, and the photovoltaic device 100 is prone to falling off the support assembly 3000 in extreme environments such as strong wind and snow.

[0054] The size L1 of the body portion 11 being greater than the size L2 of the first bending portion 12 can increase the laying area of the battery layer 18 of the body portion 11, improve the photoelectric conversion efficiency of the photovoltaic device 100, and provide a larger contact area between the photovoltaic device 100 and the support assembly 3000, so that the connection is more secure and the structural stability of the photovoltaic assembly 1000 is improved, which can better resist external environmental factors such as wind, rain, and snow.

[0055] Please refer to Figure 2 , or Figure 4 , or Figure 5 In some embodiments, in the width direction Y, the size L1 of the body portion 11 is greater than the size L3 of the second bending portion 14.

[0056] Specifically, in the width direction Y, the size L1 of the body portion 11 can be 1.2 times, 2.2 times, 3 times, 3.4 times, 4.2 times, 5.5 times, 5.8 times, 6.1 times, 7.2 times, 9.2 times, etc. of the size L3 of the second bending portion 14, which is not limited in the present application. If the size L1 of the body portion 11 is less than the size L3 of the second bending portion 14 in the width direction Y, the laying area of the battery layer 18 of the body portion 11 is insufficient, which reduces the photoelectric conversion efficiency of the photovoltaic device 100. Meanwhile, in the case where the photovoltaic device 100 is installed on the support assembly 3000, the body portion 11 is connected to or abuts against the support assembly 3000. If the size L1 of the body portion 11 is too small, the connecting area of the body portion 11 to the support assembly 3000 is insufficient, and the photovoltaic device 100 is prone to falling off the support assembly 3000 in extreme environments such as strong wind and snow.

[0057] The size L1 of the body part 11 is greater than the size L3 of the second bending part 14, which can increase the laying area of the battery layer 18 of the body part 11, improve the photoelectric conversion efficiency of the photovoltaic device 100, provide a larger contact area between the photovoltaic device 100 and the support assembly 3000, make the connection more firm, improve the structural stability of the photovoltaic assembly 1000, and better resist the influence of external environmental factors such as wind, rain, and snow.

[0058] Please refer to Figure 4 In some embodiments, the first bending part 12 and / or the second bending part 14 is provided with an opening hole 131 configured to allow at least part of the first part 31 and / or the second part 32 of the adjacent photovoltaic device 10 to pass through.

[0059] Specifically, the first bending part 12 and / or the second bending part 14 is provided with an opening hole 131 for the junction box 30 (the first part 31 and / or the second part 32) of the photovoltaic device 100 located above the photovoltaic device 100 after lapping to pass through. The opening hole 131 can be one or more, which is not limited in the present application. In one embodiment, the number of opening holes 131 corresponds to the number of junction boxes 30. In another embodiment, the number of opening holes 131 can not correspond to the number of first parts 31 or second parts 32. It can be understood that the number of first parts 31 and second parts 32 is the same. At least part of the junction box 30 can be part of the structure of the junction box 30, such as the first part 31 or the second part 32, or a cable used for connecting the battery layer 18. The opening hole 131 can be configured to provide the junction box 30, and adjacent two photovoltaic devices 100 can share one first part 31 or second part 32. In this embodiment, the opening holes 131 of the adjacent two photovoltaic devices 100 are aligned, the junction box 30 is installed in the opening holes 131 of the adjacent two photovoltaic devices 100, and the cables of the first part 31 or the second part 32 are connected to the battery layers 18 of the two photovoltaic devices 100, respectively. The opening hole 131 can also be configured to allow the cable to pass through, and the cables of different junction boxes 30 can pass through the opening hole 131 to connect to other electrical connection devices, including but not limited to other junction boxes 30, battery layers 18, energy storage devices, or loads, etc. The cross-sectional shape of the opening hole 131 can be square, circular, or elliptical, etc., which is not limited in the present application. While allowing at least part of the junction box 30 to pass through, the opening hole 131 still maintains the shielding effect of the junction box 30 through the overlapping lapping of the first bending part 12 and the second bending part 14, preventing rainwater from seeping into the second accommodating space 302 along the opening hole 131. In addition, the periphery of the opening hole 131 can be further strengthened in dustproof and waterproof performance by flanging or sealing structure.

[0060] Please refer to Figure 2 Or Figure 4 Or Figure 5In some embodiments, the first bent portion 12 includes a first extending sub-portion 121 extending from the body portion 11 and forming the first accommodating space 301 with the body portion 11. The second bent portion 14 includes a second extending sub-portion 141 extending from the body portion 11 and a second bent sub-portion 143 bent extending from an end of the second extending sub-portion 141 away from the body portion 11 and forming the second accommodating space 302 with the second extending sub-portion 141.

[0061] Specifically, the first extending sub-portion 121 extends in the thickness direction Z away from the body portion 11. The first extending sub-portion 121 and the body portion 11 of the present application are integrally formed by a part of the body portion 11 being crimped. In other embodiments of the present application, the first extending sub-portion 121 can be formed separately from the body portion 11. Further, the first bent portion 12 can further include a first bent sub-portion 123 (for example Figure 4 and Figure 5 ) bent extending from an end of the first extending sub-portion 121 away from the body portion 11 in a direction close to the body portion 11.

[0062] The second extending sub-portion 141 is used to connect the second bent portion 14 and the body portion 11. The second extending sub-portion 141 extends in the thickness direction Z away from the body portion 11. The second extending sub-portion 141 and the body portion 11 of the present application are integrally formed by a part of the body portion 11 being crimped. In other embodiments of the present application, the second extending sub-portion 141 can be formed separately from the body portion 11. The second bent sub-portion 143 extends from the second extending sub-portion 141 in a direction close to the body portion 11, thereby being bent and forming the second accommodating space 302 with the second extending sub-portion 141.

[0063] In the width direction Y, two adjacent photovoltaic components 100 are connected by the first bending part 12 of one photovoltaic panel 10 lapping the second bending part 14 of another photovoltaic panel 10. Specifically, when the photovoltaic panel 10 is installed, the second bending sub-part 143 of one photovoltaic panel 10 lapping the first extension sub-part 121 of another photovoltaic panel 10, that is, the first extension sub-part 121 of another photovoltaic panel 10 is accommodated in the second accommodation space 302 of one photovoltaic panel 10. In the case that the first bending part 12 comprises the first bending sub-part 123, the second extension sub-part 141 of one photovoltaic panel 10 lapping the first bending sub-part 123 of another photovoltaic panel 10, thereby increasing the contact area of the first bending part 12 and the second bending part 14 and improving the connection strength of the adjacent photovoltaic components 100. In this way, the second bending part 14 of one photovoltaic panel 10 can cover the first extension sub-part 121 of another photovoltaic panel 10, avoiding water flowing onto the extension sub-part 121. The mechanical locking is formed between the adjacent photovoltaic panels 10, which can prevent the photovoltaic panel 10 from displacement and loosening in the width direction Y, and enhance the structural stability of the photovoltaic assembly 1000, without the need for additional bolts or welding and other complex operations. The second extension sub-part 141 and the second bending sub-part 143 are formed in the same way, which is not described here. It should be noted that the structures of the first extension sub-part 121 and the second extension sub-part 141 can be the same or different, and the structures of the first bending sub-part 123 and the second bending sub-part 143 can be the same or different. That is, taking the middle part of the width of the photovoltaic component 100 as the center of symmetry, the first extension sub-part 121 and the second extension sub-part 141 can be symmetrical or not symmetrical, and the first extension sub-part 121 and the second extension sub-part 141 can be symmetrical or not symmetrical. For one junction box 30 of the same photovoltaic component 100, the junction box 30 can be arranged at any one of the first extension sub-part 121, the first bending sub-part 123, the second extension sub-part 141 and the second bending sub-part 143. Different junction boxes 30 can be arranged at one or more of the first extension sub-part 121, the first bending sub-part 123, the second extension sub-part 141 and the second bending sub-part 143.

[0064] In some embodiments, the first sub-body 31 is installed on the first extension sub-part 121, and a first accommodation space 301 is formed between the first extension sub-part 121 and the body part 11, so that the first sub-body 31 can be stably installed on the first extension sub-part 121, ensuring the firmness of the first sub-body 31 on the photovoltaic panel 10, and allowing the first sub-body 31 to be closer to the body part 11 where the cell layer is located, thereby shortening the distance of the electric energy transmission from the cell layer 18 to the junction box 30, reducing the electric energy loss in the transmission process, and improving the electric energy output efficiency of the photovoltaic panel 10.

[0065] In some embodiments, the second part 32 is mounted on the second extension sub-portion 141, and a second accommodating space is formed between the second extension sub-portion 141 and the body portion 11, so that the second part 32 can be stably mounted on the second extension sub-portion 141, ensuring the firmness of the second part 32 on the photovoltaic panel 10, and allowing the second part 32 to be closer to the body portion 11 where the battery layer 18 is located, shortening the distance of the transmission of electric energy from the battery layer 18 to the junction box 30, reducing the loss of electric energy in the transmission process, and improving the electric energy output efficiency of the photovoltaic panel 10. Further, the first part 31 and the second part 32 are connected to different areas of the photovoltaic panel 10, dispersing the current and further reducing the resistance, which can improve the power generation of the photovoltaic device 100.

[0066] Referring to Figure 3 or Figure 5 In some embodiments, a first angle R1 is formed between the first extension sub-portion 121 and the body portion 11, and a second angle R2 is formed between the second bending sub-portion 143 and the body portion 11, and the first angle R1 is equal to the second angle R2.

[0067] Specifically, a first angle R1 is formed between the first extension sub-portion 121 and the body portion 11, and a second angle R2 is formed between the second bending sub-portion 143 and the body portion 11, and the first angle R1 is equal to the second angle R2. The first angle R1 and the second angle R2 can be chamfered, rounded or other angles. When two photovoltaic panels 10 are overlapped, if the first angle R1 is not equal to the second angle R2, it will cause misalignment or incomplete fitting after the two photovoltaic devices 100 are overlapped, affecting the overlapping strength of the two photovoltaic devices 100. The first angle R1 equal to the second angle R2 ensures that the two photovoltaic devices 100 can be more smoothly contacted during the overlapping process, avoiding misalignment or incomplete fitting due to inconsistent angles, making the contact between the photovoltaic devices 100 more closely, which helps to improve the firmness of the connection, reduce potential problems such as water penetration caused by loose joints, and thus improve the overall performance and stability of the photovoltaic assembly 1000. At the same time, the first angle R1 equal to the second angle R2 also helps to simplify the production process and improve the production efficiency.

[0068] Referring to Figure 3 or Figure 5 In some embodiments, the first extension sub-portion 121 is a plane, and the first angle R1 is a bending angle.

[0069] Specifically, the first extension sub-part 121 is planar, simple in structure, and flat in surface, and is less likely to accumulate dust, debris, or moisture. Rainwater can flow more smoothly from the first extension sub-part 121, reducing the risk of water accumulation, thereby reducing the risk of corrosion and damage caused by water accumulation, and also reducing light scattering and obstruction caused by uneven surfaces. The bending angle refers to the internal or external angle formed between two planes. In this application, the first angle R1 is a bending angle referring to the acute angle formed between the first extension sub-part 121 and the body part 11. When subjected to external force, the bending angle can more evenly distribute stress in the plane contact area, avoiding stress concentration. Therefore, when subjected to force in the width direction Y, the first angle R1 as a bending angle can withstand more stress, avoiding disconnection between adjacent photovoltaic components 100, and enhancing the connection strength between adjacent photovoltaic components 100. Further, the first bending sub-part 123 is planar, which has the same beneficial effects as the first extension sub-part 121.

[0070] Please refer to Figure 3 or Figure 5 In some embodiments, the second extension sub-part 141 and the second bending sub-part 143 are planar, and the second angle R2 is a bending angle.

[0071] Specifically, the second extension sub-part 141 and the second bending sub-part 143 are planar, simple in structure, and flat in surface, and are less likely to accumulate dust, debris, or moisture. Rainwater can flow more smoothly from the second extension sub-part 141 and the second bending sub-part 143, reducing the risk of water accumulation, thereby reducing the risk of corrosion and damage caused by water accumulation, and also reducing light scattering and obstruction caused by uneven surfaces. The bending angle refers to the internal or external angle formed between two planes. In this application, the second angle R2 is a bending angle referring to the acute angle formed between the second extension sub-part 141 and the second bending sub-part 143. When subjected to external force, the bending angle can more evenly distribute stress in the plane contact area, avoiding stress concentration. Therefore, when subjected to force in the width direction Y, the second angle R2 as a bending angle can withstand more stress, avoiding disconnection between adjacent photovoltaic components 100, and enhancing the connection strength between adjacent photovoltaic components 100.

[0072] Further, the third angle R3 formed between the first extension sub-section 121 and the first bending sub-section 123, the fourth angle R4 formed between the second extension sub-section 141 and the second bending sub-section 143, and the third angle R3 and the fourth angle R4 can be the same or different. When the third angle R3 and the fourth angle R4 are the same, more surfaces of the adjacent photovoltaic components 100 can be in contact when the adjacent photovoltaic components 100 are overlapped. In other words, when the third angle R3 and the fourth angle R4 are the same, the second extension sub-section 141 of one photovoltaic component 100 and the first bending sub-section 123 of another photovoltaic component 100 are overlapped, and the second bending sub-section 143 of one photovoltaic component 100 and the first extension sub-section 121 of another photovoltaic component 100 are overlapped. Thus, the overlapped area of the adjacent photovoltaic components 100 is larger, and the connection strength is higher.

[0073] When the third angle R3 and the fourth angle R4 are different, the second extension sub-section 141 of one photovoltaic component 100 and the first bending sub-section 123 of another photovoltaic component 100 are overlapped, or the second bending sub-section 143 of one photovoltaic component 100 and the first extension sub-section 121 of another photovoltaic component 100 are overlapped. Taking the first type of overlap as an example, the first bending sub-section 123 of one photovoltaic component 100 and the second extension sub-section 141 of another photovoltaic component 100 are not in contact, and there is a certain interval. The interval can be used for other structures of the photovoltaic assembly 1000. The third angle R3 and the fourth angle R4 can be the same or different to adapt to different installation environments, such as different angle roof slopes or other special-shaped support assemblies 3000, thereby improving the versatility and applicability of the photovoltaic assembly 1000.

[0074] Please refer to Figure 2 , or Figure 4 , or Figure 5 In some embodiments, the photovoltaic panel 10 further comprises a connecting portion (not shown) arranged on at least two opposite sides of the body portion 11 in the length direction X. In the length direction X, the adjacent two photovoltaic components 100 are connected by the connecting portion.

[0075] Specifically, in the case of multiple photovoltaic pieces 100, the photovoltaic pieces 100 are arranged in sequence along the length direction X and / or the width direction Y to cover the roof. Two photovoltaic pieces 100 adjacent along the length direction X are connected by a connecting part. The connecting part can be a buckle, a screw, or the like structure, which can prevent displacement and loosening of the photovoltaic piece 100 in the length direction X, avoid misalignment of the photovoltaic module 1000 due to long-term use or external factors, and improve the stability of the photovoltaic module 1000. The connecting part can be one or more, which is not limited in the present application. For example, one photovoltaic panel 10 of the present application includes two connecting parts. The connecting part is provided at least on the body part 11, and in other embodiments of the present application, the connecting part can also be provided on one or more of the first bending part 12, the second bending part 14, and the body part 11. For example, the connecting part can be provided on the body part 11 and the first bending part 12, and the connecting part is connected to the opposite sides of the body part 11 in the length direction X. Thus, the overall size of the connecting part is relatively large, and in the case of connecting two adjacent photovoltaic pieces 100 by the connecting part, the connecting parts of the two adjacent photovoltaic pieces 100 have a relatively large connecting area, which can improve the installation stability of the photovoltaic piece 100 in the length direction X.
