[0005] The photovoltaic tile of the application embodiment forms first included angle by vertical plate and main body plate, and two lock edge structures are overlapped, so that two vertical plates on the lock edge structure overlapped enclose ventilation channel, so that ventilation channel can be penetrated along the edge of main body plate, i.e. the edge of laminated assembly, to realize good ventilation effect, and then be conducive to heat dissipation and waterproof. In addition, two vertical plates enclosing ventilation channel form first included angle with the main body plate connected respectively, to form inclined plane, and also be conducive to waterproof.

[0006] In some embodiments, the first included angle α is in the range of 90°<α<180°.

[0039] Referring to Figures 1-3 The photovoltaic tile 100 of the embodiment of the application comprises a laminated assembly 10 and a back plate 20, the laminated assembly 10 comprises a front plate 11 and a cell sheet 12, the front plate 11 covers the cell sheet 12; the back plate 20 comprises a main plate 21 and a locking edge structure 30, the main plate 21 covers the side surface of the cell sheet 12 away from the front plate 11, and the locking edge structure 30 is arranged at the edge of the main plate 21 and is located outside the edge of the laminated assembly 10; the locking edge structure 30 comprises a vertical plate 31 connected with the main plate 21, the vertical plate 31 forms a first included angle a with the main plate 21, and the locking edge structure 30 is configured to overlap with the locking edge structure 30 of another photovoltaic tile 100 and jointly form a ventilation channel 303.

[0040] The photovoltaic tile 100 of the embodiment of the application forms the first included angle a between the vertical plate 31 and the main plate 21, and the two locking edge structures 30 overlap with each other, so that the two vertical plates 31 on the overlapping locking edge structures 30 enclose the ventilation channel 303, so that the ventilation channel 303 can pass through the edge of the main plate 21, that is, the edge of the laminated assembly 10, to achieve good ventilation effect, thereby facilitating heat dissipation and waterproofing. In addition, the two vertical plates 31 enclosing the ventilation channel 303 form a first included angle a with the connected main plate 21 respectively, thereby forming an inclined surface, which is also conducive to waterproofing.

[0041] Specifically, the photovoltaic tile 100 can be applied to a building surface or an outdoor flat ground, for example, the photovoltaic tile 100 can be laid on a roof, a wall surface or a public facility such as a street lamp, and for another example, the photovoltaic tile 100 can also be laid in a large area to build a photovoltaic power generation base. The cell sheet 12 is used to convert light energy into electrical energy. The cell sheet 12 can be a crystalline silicon cell manufactured by using Perc (Passivated Emitter Rear Cell), Topcon (Tunnel Oxide Passivated Contact) or HJT (Heterojunction with Intrinsic Thin-film) technology, or can be a perovskite cell.

[0042] The front plate 11 and the back plate 20 cover the two side surfaces of the battery piece 12 in the thickness direction, so as to protect the battery piece 12. It should be noted that the front plate 11 and the back plate 20 covering the surface of the battery piece 12 means that the projection range of the front plate 11 and the back plate 20 on the battery piece 12 in the thickness direction can cover the surface of the corresponding side of the battery piece 12, and the direct contact between the front plate 11 and the battery piece 12 and the direct contact between the back plate 20 and the battery piece 12 are not limited.

[0043] Optionally, a weather-resistant film, a waterproof film, an adhesive film, or other functional laminated layers are arranged in the laminated assembly 10. The layers in the laminated assembly 10 and the back plate 20 are sequentially laminated along the thickness direction of each layer. It can be understood that the thickness direction of the photovoltaic tile 100 is consistent with the thickness direction of the laminated assembly 10 (and each layer in the laminated assembly 10) and the back plate 20.

[0044] Optionally, the photovoltaic tile 100 is in a flat plate shape, and the main plate 21 of the back plate 20 and each layer in the laminated assembly 10 are all in a flat plate structure.

[0045] The photovoltaic tile 100 is usually laid with the front plate 11 on top and the back plate 20 on the bottom. For the sake of description, the direction from the front plate 11 to the back plate 20 along the thickness direction of the photovoltaic tile 100 is defined as the direction from top to bottom. The side surface of the battery piece 12 facing the front plate 11 is the light-receiving surface, and the laminated layers above the battery piece 12 in the laminated assembly 10 are all transparent.

[0046] Optionally, the front plate 11 can be made of high-transparency resin, plastic, glass, or other materials. For example, the front plate 11 can be a transparent PET (polyethylene terephthalate) plate. For another example, the front plate 11 can be a colorless glass plate.

[0047] Optionally, the projections of the front plate 11 in the thickness direction on the plane of the battery piece 12 coincide with each other.

[0048] Optionally, the back plate 20 and the laminated assembly 10 can be laminated as a whole, or connected through fixing members such as locking screws, rivets, or have a glue layer between the back plate 20 and the laminated assembly 10, and the back plate 20 and the laminated assembly 10 are connected through gluing.

[0049] Optionally, the back plate 20 is an aluminum or aluminum alloy plate, a color steel plate, an aluminum-zinc plated plate, a zinc plated plate, or the like.

[0050] The back plate 20 has at least two opposite side edges that exceed the side edges of the laminated assembly 10 on the same side. The locking edge structure 30 is arranged at the two side edges of the back plate 20 that exceed the laminated assembly 10, and is overlapped with the locking edge structure 30 of another photovoltaic tile 100 adjacent to the back plate 20 in the opposite direction of the two side locking edge structures 30.

[0051] The locking structure 30 and the main plate 21 are both rigid members and are rigidly connected, so that the back plate 20 can be connected with another back plate 20 through the locking structure 30 and the locking structure 30 of the other back plate 20. Alternatively, the locking structure 30 is also made of metal material. Further, the main plate 21 and the locking structure 30 are integrally formed.

[0052] The vertical plate 31 extends obliquely upward from the edge of the main plate 21. The width of the vertical plate 31 is obviously smaller than that of the main plate 21. The vertical plate 31 can be arranged at the opposite two side edges of the main plate 21, and the two vertical plates 31 connected with the same main plate 21 can extend toward the left upper and right upper directions respectively.

[0053] The vertical plate 31 can extend along the edge of the main plate 21 in a strip shape, and the two locking structures 30 that are overlapped with each other form a ventilation channel 303 that penetrates along the edge of the main plate 21.

[0054] In some embodiments, the first included angle α is in the range of 90°<α<180°.

[0055] In this way, by setting the first included angle α as an obtuse angle, the two vertical plates 31 that are overlapped with each other are inclined toward each other, which is beneficial to waterproofing and guiding water flow.

[0056] Specifically, the vertical plate 31 is a planar plate, the vertical plate 31 is overlapped with a side vertical plate 31 on another back plate 20 and encloses the ventilation channel 303. The first included angle α is formed between the side surface of the vertical plate 31 away from the ventilation channel 303 and the main plate 21.

[0057] Alternatively, the locking structure 30 is arranged at the two side edges of the back plate 20 opposite in the first direction, the two side edges of the main plate 21 in the first direction are respectively connected with the two vertical plates 31, and the two first included angles α formed by the two vertical plates 31 and the main plate 21 are directed toward opposite directions. The same main plate 21 and the two vertical plates 31 can form two first included angles α that are equal in size, or can form two first included angles α that are different in size.

[0058] For example, the first included angle α can be 112.5°, 116°, 120°, etc.

[0059] Please refer to Figure 3 and Figure 6 In some embodiments, the vertical plate 31 and the vertical plate 31 of the overlapped another back plate 20 form a second included angle β, and the second included angle β is in the range of 45°≤β≤60°.

[0060] In this way, by setting the second included angle β formed by the vertical plate 31 and the overlapped another vertical plate 31 in a reasonable angle range, the stability of the overlapping of the two locking structures 30 is improved, and it is also beneficial to the ventilation channel 303 to realize a continuous and stable ventilation effect.

[0061] Specifically, the second included angle β can be 45°, 48°, 53°, 56°, or 60°. The second included angle β is formed in the ventilation channel 303. The two standing plates 31 together with the installation surface 1001 on which the photovoltaic tiles 100 are laid form the ventilation channel 303, and the second included angle β is opposite to the installation surface 1001. The cross-sectional shape of the ventilation channel 303 can be triangular.

[0062] In some embodiments, the installation surface 1001 is a plane parallel to the main plate 21, the two standing plates 31 that are overlapped with each other have the same length, and the first included angle α formed by the two standing plates 31 and the main plate 21 is the same. The cross-sectional shape of the ventilation channel 303 is isosceles triangular, and the second included angle β is the vertex angle. In this embodiment, the supplementary angle of the first included angle α is half of the supplementary angle of the second included angle β, that is, the first included angle α and the second included angle β satisfy the following relationship: 180°-α=1 / 2×(180°-β). 1

[0063] Optionally, in the photovoltaic assembly 1000, the plurality of photovoltaic tiles 100 are electrically connected and connected with each other through the edge locking structure 30 at the adjacent edges. The second included angle β defined between each two standing plates 31 that are overlapped with each other can be the same angle, thereby facilitating standardized production and assembly and disassembly.

[0064] In other embodiments, the second included angle β in the photovoltaic assembly 1000 can also be of different angles.

[0065] Please refer to Figure 3 In some embodiments, the standing plate 31 and the standing plate 31 of the other back plate 20 that are overlapped together form the ventilation channel 303, and the height of the ventilation channel 303 ranges from 18 mm to 68 mm.

[0066] In this way, by setting the height of the ventilation channel 303 within a reasonable range, a good ventilation effect is achieved.

[0067] Specifically, the standing plate 31 includes a first end A connected to the main plate 21 and a second end B away from the main plate 21. The second ends B of the two standing plates 31 that are overlapped with each other abut against each other, and the second end B is located at the farthest position from the main plate 21 on the standing plate 31. The height of the ventilation channel 303 refers to the vertical distance from the second end B to the plane on which the main plate 21 is located. For example, the height of the ventilation channel 303 can be 18 mm, 21 mm, 33 mm, 36 mm, 45.5 mm, 57 mm, or 68 mm.

[0068] Please refer to Figures 3-5 In some embodiments, the standing plate 31 includes a first end A and a second end B, the first end A is connected to the main plate 21, and the second end B is away from the main plate 21. The second end B is configured to abut against the second end B of the other standing plate 31 when the back plate 20 is overlapped with the other back plate 20.​

[0069] Thus, the second ends B of the two mutually overlapped vertical plates 31 abut against each other, and the two first ends A are connected to the edges of the main plate 21, so that the cross section of the two vertical plates 31 is in the shape of an inverted "V", thereby facilitating the stability of the overlapped structure.

[0070] Specifically, the two mutually overlapped vertical plates 31 are respectively a first vertical plate 311 and a second vertical plate 312, the first ends A of the first vertical plate 311 and the second vertical plate 312 are spaced apart by a certain distance, and the second ends B of the first vertical plate 311 and the second vertical plate 312 abut against each other. The first vertical plate 311 and the second vertical plate 312 are both flat plates, a second included angle β is formed between the first vertical plate 311 and the second vertical plate 312, and the angle range of the second included angle β is 45°-60°, and the first vertical plate 311 and the second vertical plate 312 are in the shape of an inverted "V".

[0071] Optionally, the two main plates 21 of the two mutually overlapped back plates 20 are both laid flat on the mounting surface 1001, and the ventilation channel 303 is enclosed between the first vertical plate 311, the second vertical plate 312 and the mounting surface 1001, and the cross section of the profile of the ventilation channel 303 is in the shape of a triangle, thereby having high structural stability.

[0072] Please refer to Figures 3-5 In some embodiments, the edge locking structure 30 comprises a mounting portion 32, the mounting portion 32 is connected to the second end B and forms a curved surface, the line BC connecting the second end B and the terminal end C of the mounting portion 32 forms a third included angle with the vertical plate 31, and the mounting portion 32 is used to connect with the mounting portion 32 of the other edge locking structure 30 which is overlapped.

[0073] Thus, the mounting portion 32 forms a curved surface, the line BC connecting the second end B and the terminal end C of the mounting portion 32 forms a third included angle with the vertical plate 31, and the mounting portion 32 is connected with the mounting portion 32 of the other edge locking structure 30 which is overlapped, thereby preventing the two mutually overlapped edge locking structures 30 from slipping out to a certain extent.

[0074] Specifically, the terminal end C of the mounting portion 32 is the end portion away from the second end B. The starting point of the curved surface is located at the second end B, the terminal end of the curved surface is located at the terminal end C of the mounting portion 32, and the curved surface protrudes outwardly with respect to the line BC connecting the second end B and the terminal end C. The mounting portions 32 of the two mutually overlapped edge locking structures 30 are fixedly connected, and can be detachably connected through at least one of the following modes: clamping and connecting, fastener connecting, adhesive connecting, etc.

[0075] Optionally, the curved surface is a circular arc surface, and the line BC connecting the second end B and the terminal end C is a chord of the circle on which the circular arc surface is located.

[0076] Optionally, the first upright plate 311 is connected with a first mounting portion 321 at the second end B, and the second upright plate 312 is connected with a second mounting portion 322 at the second end B. An end C of the first mounting portion 321 and the second end B form a first third angle θ1 with the first upright plate 311, and an end C of the second mounting portion 322 and the second end B form a second third angle θ2 with the second upright plate 312. The first third angle θ1 is smaller than the second third angle θ2, i.e., θ1 < θ2.

[0077] Referring to Figure 3 and Figure 6 In some embodiments, the mounting portion 32 overlaps and abuts with the mounting portion 32 of the other lock edge structure 30 that is overlapped.

[0078] In this way, the mounting portion 32 overlaps and abuts with the mounting portion 32 of the other lock edge structure 30 that is overlapped, thereby further improving the connection strength and the friction between the two mounting portions 32, preventing slippage, and improving the installation convenience.

[0079] Specifically, in the two lock edge structures 30 that are overlapped, the first upright plate 311 coincides with the second end B of the second upright plate 312, and the curved surface of the first mounting portion 321 overlaps the curved surface of the second mounting portion 322. For example, the first mounting portion 321 and the second mounting portion 322 are formed with circular arc surfaces that overlap each other. The end C of the first mounting portion 321 can slightly exceed the end C of the second mounting portion 322 in the tangential direction, or vice versa, or the end C of the first mounting portion 321 can be flush with the end C of the second mounting portion 322.

[0080] In some embodiments, the end C of the first mounting portion 321 is flush with the end C of the second mounting portion 322, and the end C of the first mounting portion 321 and the end C of the second mounting portion 322 coincide with the line BC connecting the second end B, which forms a first third angle θ1 with the first upright plate 311 and a second third angle θ2 with the second upright plate 312. Obviously, the first third angle θ1 is the difference between the angle of the second third angle θ2 and the second angle β, i.e., θ1 = θ2 - β.

[0081] Referring again to Figure 1 The photovoltaic assembly 1000 of the embodiments of the present application includes a plurality of photovoltaic tiles 100, which are electrically connected and arranged at least along a first direction, and the lock edge structures 30 of two adjacent photovoltaic tiles 100 along the first direction are overlapped and formed with the ventilation channel 303.

[0082] In this way, the electrical connection of multiple photovoltaic tiles 100 can increase the power generation, the locking edges 30 of two adjacent photovoltaic tiles 100 are overlapped to form the ventilation channel 303, thereby improving the ventilation and waterproof effect of the photovoltaic assembly 1000, and in addition, the photovoltaic assembly 1000 can be installed conveniently without additional ventilation openings.

[0083] Specifically, the photovoltaic tile 100 has two locking edges 30 formed on two opposite side edges in the first direction, one of which includes the first vertical plate 3111, and the other of which includes the first vertical plate 3112. The first vertical plate 3112 of the photovoltaic tile 100 is overlapped with the first vertical plate 3111 of the next photovoltaic tile 100 in the first direction to form the ventilation channel 303.

[0084] Optionally, in some embodiments, the multiple photovoltaic tiles 100 are arranged in the first direction and the second direction, and the first direction and the second direction form an included angle. The photovoltaic tiles 100 arranged in the first direction are provided with the locking edges 30 on two opposite side edges in the first direction and are overlapped in the first direction by the locking edges 30 in sequence; the photovoltaic tiles 100 arranged in the second direction are provided with the locking edges 30 on two opposite side edges in the second direction and are overlapped in the second direction by the locking edges 30 in sequence. The outermost photovoltaic tile 100 in the first direction can be overlapped with the outermost photovoltaic tile 100 in the second direction. In this embodiment, the photovoltaic tiles 100 arranged in the first direction can be arranged on different installation surfaces 1001 as the photovoltaic tiles 100 arranged in the second direction.

[0085] Optionally, in some other embodiments, the multiple photovoltaic tiles 100 are arranged in the first direction and the second direction, the first direction and the second direction can form an included angle, and the first direction and the second direction are parallel to the same installation surface 1001. The vertical plates 31 on the multiple photovoltaic tiles 100 can be parallel to each other in the first direction and extend in the second direction in a strip shape.

[0086] Please refer to Figure 1 and Figure 3 In some embodiments, the locking edge 30 includes a mounting portion 32 connected with the vertical plate 31, the mounting portion 32 is arranged at the edge of the vertical plate 31 away from the main plate 21, and the mounting portion 32 is configured to overlap with the mounting portion 32 of the other locking edge 30 that is overlapped.

[0087] The photovoltaic assembly 1000 includes a first fastener 41, the first fastener 41 is arranged through the two mounting portions 32 that overlap with each other to fixedly connect the two mounting portions 32.
