[0001] This application relates to the field of photovoltaic system technology, and in particular to a curved photovoltaic tile and its installation system. Background Technology

[0002] In recent years, with the accelerating and deepening trend of building-integrated photovoltaics (BIPV), the use of photovoltaic tiles to replace ordinary clay tiles has become increasingly common, which can effectively reduce carbon emissions and achieve the goal of energy conservation and environmental protection.

[0003] Traditional residential photovoltaic systems typically involve installing square photovoltaic panels on rooftops or sheds. However, with increasing user demands for aesthetics and technological advancements, new curved photovoltaic tiles have emerged on the market, which are better suited to Chinese-style roofs.

[0004] However, the inventors believe that the above-mentioned technologies have the following drawbacks: due to the structural limitations of curved photovoltaic tiles, it is usually necessary to make holes in the curved photovoltaic tiles to achieve connection and fixation. However, the holes in common curved photovoltaic tiles are arranged in the trough position, resulting in poor waterproof performance. At the same time, curved photovoltaic tiles are stacked, making it difficult to disassemble and maintain a single curved photovoltaic tile, and resulting in poor wind uplift resistance.

[0037] One or more embodiments of this application disclose a curved photovoltaic tile, with reference to... Figures 1 to 9 The system includes a photovoltaic tile body 11 and a mounting bracket 12. The mounting bracket 12 has a first slot 121. The photovoltaic tile body 11 has at least one crest 111, on which a first connecting hole 1111 is adapted to be formed. The edge of the crest 111 is adapted to be inserted into the first slot 121, so that the mounting bracket 12 is adapted to be connected and fixed to the photovoltaic tile body 11 through the first connecting hole 1111. The mounting bracket 12 is adapted to connect to the building surface structure. Arranging the mounting bracket 12 at the crest 111 can solve the problem that in traditional photovoltaic tiles, the connection structure is located at the trough and the contact edge of the photovoltaic tile body 11 is prone to failure. To prevent water accumulation and seepage, the photovoltaic tile body 11 is designed to have good waterproof and water-conducting properties, thus achieving higher stability in use. At the same time, the pre-installed brackets 12 effectively reduce the installation difficulty of the photovoltaic tile body 11 and improve its wind resistance. In addition, the brackets 12 are connected at the crest 111 of the photovoltaic tile body 11, which can make full use of the space below the crest 111 to connect with the building surface, so that the installed photovoltaic tile body 11 can be closer to the building surface, improving stability and aesthetics.

[0038] Specifically, the way the hanger 12 is connected and fixed to the photovoltaic tile body 11 through the first connecting hole 1111 is as follows: the first slot portion 121 has second connecting holes 1211 on both sides. The first connecting hole 1111 and the second connecting hole 1211 are suitable for connection and fixation by bolts and nuts. The hanger 12 can be pre-fixed to the photovoltaic tile body 11 relatively easily by the bolt and nut connection method. At the same time, the hanger 12 and the photovoltaic tile body 11 have high connection stability.

[0039] In some embodiments, the bolts and nuts are made of stainless steel to improve their long-term service life in outdoor environments.

[0040] like Figure 1 and 6 In the illustrated embodiment, multiple wave crests 111 are provided with first connecting holes 1111. The wave crests 111 with the first connecting holes 1111 have the same shape as each other. The shape is consistent, meaning that the curvature and height of the wave crests 111 are consistent. The opening positions of the first connecting holes 1111 are also consistent, meaning that the opening orientation of the first connecting holes 1111 at the wave crests 111 is consistent. The purpose of this is that when there are multiple hangers 12, the state of each hanger 12 can also be consistent, which facilitates the unified connection between each hanger 12 and the building surface, reduces the fine-tuning operation during the installation process, and improves the installation efficiency.

[0041] like Figure 3 In the embodiment shown, the first slot portion 121 is covered with a flexible layer 1212, which can form a soft isolation and seal between the photovoltaic tile body 11 and the hanger 12, thereby protecting the photovoltaic tile body 11 and improving waterproof performance.

[0042] In some embodiments, the flexible layer 1212 is an adhesive strip, which is pre-attached to the first groove portion 121. The adhesive strip at least surrounds and covers the first connecting hole 1111, so that when the hanger 12 is connected and fixed to the photovoltaic tile body 11, it can seal and waterproof the first connecting hole 1111 and the second connecting hole 1211.

[0043] In some embodiments, the width of the first slot portion 121 is slightly wider than the thickness of the photovoltaic tile body 11, so that the photovoltaic tile body 11 can be inserted into the first slot portion 121. The gap between the first slot portion 121 and the photovoltaic tile body 11 can be filled by the flexible layer 1212.

[0044] like Figures 1 to 5 In the embodiment shown, a waterproof strip 117 is laid on the front side of the photovoltaic tile body 11 along the laying direction of the hanger 12 (see reference). Figure 4(in the horizontal direction), the waterproof strip 117 is located on the side of the first connecting hole 1111 closer to the edge of the photovoltaic tile body 11. The waterproof strip 117 passes through the hanger 12. When the curved photovoltaic tile 1 is installed, the top of the waterproof strip 117 can contact the curved photovoltaic tile 1 above, so as to achieve a waterproof seal between the two curved photovoltaic tiles 1.

[0045] like Figure 6 In the embodiment shown, the photovoltaic tile body 11 includes a glass layer 112, a first adhesive film layer 113, a solar cell 114, a second adhesive film layer 115, and a backsheet layer 116. The glass layer 112, the first adhesive film layer 113, the solar cell 114, the second adhesive film layer 115, and the backsheet layer 116 are suitable for lamination within a curved mold, which simplifies the process, reduces production costs, and allows for mass production.

[0046] In some embodiments, the glass layer 112 includes, but is not limited to, ultra-clear semi-tempered glass, tempered glass, ultra-clear glass, and rolled glass.

[0047] In some embodiments, the first adhesive film layer 113 and the second adhesive film layer 115 are not limited to fixed materials and thicknesses, and can be materials such as EVA, POE, and PVB to meet the requirements of photovoltaic panel lamination. The thickness is generally 0.38 mm to 0.38*n mm, where n is a positive integer.

[0048] In some embodiments, the backsheet layer 116 can be a TPT backsheet, a KPK backsheet, a polymer composite backsheet, or a metal material that meets the requirements for lamination.

[0049] In some embodiments, the solar cell 114 is a plurality of narrow strip solar cells, which can reduce the impact of the curved surface of the photovoltaic tile body 11 on the solar cell 114. Preferably, seven crystalline silicon solar cells can be provided in the product, and one crystalline silicon solar cell is divided into six narrow strip monocrystalline silicon solar cells.

[0050] In some embodiments, the battery cell 114 is a flexible battery cell, which can increase fit and coverage area.

[0051] like Figure 1 , 2 In the embodiments shown in 4 and 5, a junction box 13 is attached to the back of the photovoltaic tile body 11. The junction box 13 is installed on the back of the crest portion 111, which can make full use of the back space of the photovoltaic tile body 11 and improve the structural compactness.

[0052] like Figure 5 and 9In the illustrated embodiment, a first frame 14 and a second frame 15 are respectively provided at both ends of the photovoltaic tile body 11. The first frame 14 is provided with an overlap groove 141, and the second frame 15 is provided with an overlap hook 151. The overlap groove 141 and the overlap hook 151 are adapted to overlap and connect with each other to prevent the first frame 14 and the second frame 15 from separating from each other (see reference). Figure 9 (Horizontal direction in the middle).

[0053] In some embodiments, the first frame 14 and the second frame 15 are sealed and bonded to the edge of the photovoltaic tile body 11. Specifically, the first frame 14 and the second frame 15 are bonded to the edge of the photovoltaic tile body 11 using sealant.

[0054] In some embodiments, the overlap groove 141 is provided along the entire length of the first frame 14. The overlap groove 141 is adapted to be continuously provided along the length direction of the first frame 14, so that the overlap groove 141 and the overlap hook 151 can obtain a larger engagement range, thereby effectively reducing the docking difficulty of the first frame 14 and the second frame 15 and improving the connection strength of the first frame 14 and the second frame 15.

[0055] In some embodiments, the lap hook 151 is provided along the entire length of the second frame 15. The lap hook 151 is adapted to be continuously provided along the length direction of the second frame 15, so that the lap groove 141 and the lap hook 151 can obtain a larger engagement range, thereby effectively reducing the docking difficulty of the first frame 14 and the second frame 15 and improving the connection strength of the first frame 14 and the second frame 15.

[0056] The first frame 14 and the second frame 15 are suitable for overlapping. The overlap groove 141 is located at the bottom and the overlap hook 151 is located at the top. The overlap groove 141 can receive and guide rainwater out, and only a small amount of rainwater can pass through the gap between adjacent photovoltaic tiles, which can effectively improve the waterproof performance. At the same time, since the overlap groove 141 is set along the entire length of the first frame 14, it can drain the rainwater at the overlap, thus improving the overall waterproof capability.

[0057] In some embodiments, the first frame 14 and the second frame 15 can be made of metal materials such as aluminum alloy and steel, or non-metal materials such as polymer resin and engineering plastic.

[0058] One or more embodiments of this application disclose an installation system, referring to... Figures 1 to 9The system includes a support structure 2, a base 3, a wind-resistant hook 4, and a curved photovoltaic tile 1 according to any of the above embodiments. The support structure 2 is suitable for being fixedly installed on the building surface, and the base 3 is suitable for being fixedly installed on the support structure 2. A connecting groove 31 is provided on the base 3. A hook 122 is provided on the back of the photovoltaic tile body 11 by the hanger 12. The hook 122 is suitable for cooperating with the connecting groove 31 to restrict the photovoltaic tile body 11 from moving away from the building surface. A second groove 41 and a connecting part 42 are provided on the wind-resistant hook 4. The second groove 41 is suitable for accommodating the edge of the photovoltaic tile body 11 away from the side where the hanger 12 is provided. A connecting part 123 is provided on the front of the photovoltaic tile body 11 by the hanger 12. The connecting part 42 and the connecting part 123 are suitable for cooperating and fixing. By disconnecting the hanger 12 and the base 3 and the hanger 12 and the wind-resistant hook 4, the disassembly, assembly, maintenance and repair of a single curved photovoltaic tile 1 can be realized.

[0059] like Figure 8 In the embodiment shown, the main body of the hook 122 is L-shaped, and the main body of the connecting groove 31 is U-shaped. The connecting groove 31 is horizontal. When the hook 122 is connected to the connecting groove 31, the lower end of the hook 122 is adapted to abut the bottom of the connecting groove 31 to achieve stable support. When the curved photovoltaic tile 1 is blown up by the wind, the lower end of the hook 122 will be lifted up and then restricted by the top of the connecting groove 31 to prevent the hanger 12 and the base 3 from detaching from each other.

[0060] like Figures 7 to 8 In the embodiment shown, a limiting part 32 is provided on the base 3. The limiting part 32 is located in the direction in which the hook 122 disengages from the connecting groove 31. When the hook 122 is connected to the connecting groove 31, a limiting cavity 33 with an opening is formed between the hook 122 and the limiting part 32. The limiting cavity 33 is suitable for embedding the anti-detachment block 5 from the opening to improve structural stability, restrict the hook 122 from disengaging from the connecting groove 31, and reduce the probability that the lower curved photovoltaic tile 1 will move upward and detach from the base 3 under wind load.

[0061] like Figure 8 In the embodiment shown, the limiting part 32 is a baffle structure. When the hook 122 is connected to the connecting groove 31, the side of the hook 122 located in the limiting cavity 33 is parallel to the side of the limiting part 32 located in the limiting cavity 33. This allows the anti-detachment block 5 to smoothly enter the limiting cavity 33 under the parallel structure formed by the hook 122 and the limiting part 32, reducing the installation difficulty of the anti-detachment block 5. It is worth noting that the direction of the anti-detachment block 5 entering the limiting cavity 33 and the direction of the hook 122 leaving the connecting groove 31 need to be set differently so that the two can form motion interference.

[0062] like Figure 8In the embodiment shown, the opening of the connecting groove 31 is perpendicular to the surface of the limiting part 32, and the thickness of the anti-detachment block 5 is not less than the depth of the connecting groove 31, so that the hook 122 can remain stable under the joint operation of the connecting groove 31 and the anti-detachment block 5, reducing the probability of the hook 122 deflecting relative to the connecting groove 31.

[0063] like Figure 8 In the embodiment shown, the opening of the limiting cavity 33 faces the hanger 12, and part of the limiting cavity 33 is located below the hanger 12. The thickness of the anti-detachment block 5 is less than the distance from the top of the limiting baffle to the hanger 12, ensuring the smooth installation of the anti-detachment block 5 and enabling the main structure of the hanger 12 to interfere with the detachment of the anti-detachment block 5, thereby improving the stability of the installation system.

[0064] like Figure 8 In the embodiment shown, the joint 42 and the connecting part 123 protrude from the upper part of the first slot 121 and the lower part of the second slot 41, respectively. The joint 42 and the connecting part 123 are adapted to cooperate to form an installation gap 6 between two adjacent photovoltaic tile bodies 11. The joint 42 and the connecting part 123 are adapted to be fixedly connected through the installation gap 6. The installation gap 6 can be exposed to the outside world, so that the installer can release the connection between the wind-resistant hook 4 and the hanger 12 from the installation gap 6.

[0065] In some embodiments, the waterproof strip 117 laid on the front of the photovoltaic tile body 11 can support the upper and lower adjacent photovoltaic tile bodies 11 to initially form an installation gap 6, reducing the difficulty of connecting and cooperating the wind-resistant hook 4 and the hanger 12.

[0066] like Figure 8 In the embodiment shown, a third connecting hole and a fourth connecting hole are provided on the joint 42 and the connecting part 123 along the depth direction of the installation gap 6. The third connecting hole and the fourth connecting hole are suitable for connection by threaded fasteners, so that the installer can release the connection between the wind-resistant hook 4 and the hanger 12 from the outside of the installation gap 6.

[0067] like Figure 8 In the embodiment shown, positioning blocks 421 and positioning grooves 1231 are respectively provided on the joint 42 and the connecting part 123. The joint 42 and the connecting part 123 are adapted to engage with each other along the depth direction of the installation gap 6, so that the third connecting hole and the fourth connecting hole are aligned. The positioning blocks 421 and positioning grooves 1231 can effectively reduce the difficulty of aligning the third connecting hole and the fourth connecting hole, thereby reducing the difficulty of connecting the wind-resistant hook 4 and the hanger 12.

[0068] like Figure 9In the embodiment shown, the support structure 2 includes a bolt group 21, a support base 22, a water-following strip 23, and a tile-hanging strip 24. The bolt group 21 is adapted to connect the building surface and the support base 22. The water-following strip 23 is adapted to be disposed on the support base 22 along a first direction. The tile-hanging strip 24 is adapted to be disposed on the water-following strip 23 along a second direction, which is perpendicular to the insertion and mating direction of the hanger 12 and the photovoltaic tile body 11. A limiting rib 34 is provided protruding from the lower side of the base 3. The limiting rib 34 is adapted to abut against the tile-hanging strip 24 to limit the relative movement of the base 3 and the tile-hanging strip 24.
