[0076] See also Figure 1 At least one embodiment of the present application provides a photovoltaic tile 1, which includes a photovoltaic laminate 10, a first frame 11 and a second frame 12. The first frame 11 is installed on one side of the photovoltaic laminate 10, and the first frame 11 is provided with a first water guide groove 111. The second frame 12 is installed on the other side of the photovoltaic laminate 10 away from the first frame 11, and the second frame 12 is provided with a second water guide groove 121. When adjacent photovoltaic tiles 1 are overlapped, the first frame 11 overlaps with the second frame 12 of the adjacent photovoltaic tiles 1, and the first water guide groove 111 and the second water guide groove 121 are staggered in the vertical direction.

[0077] According to the photovoltaic tiles 1 of the embodiment of the present application, when adjacent photovoltaic tiles 1 are overlapped, the first water guide grooves 111 and the second water guide grooves 121 are staggered in the vertical direction to form a vertical double-layer water guide structure, and rainwater leaking from the roof into the first water guide grooves 111 and the second water guide grooves 121 is discharged through both sides of the first water guide grooves 111 and the second water guide grooves 121, thereby improving the waterproof effect.

[0078] In some embodiments, when adjacent photovoltaic tiles 1 are overlapped, the first water channel 111 is located above the second water channel 121. A water channel 1112 is formed between the first water channel 111 and the second frame 12, and the water channel 1112 connects the first water channel 111 and the second water channel 121. The water channel 1112 allows rainwater overflowing from the first water channel 111 to flow to the second water channel 121. Specifically, rainwater leaking downward from the connection between the first seal 15 and the second seal 16 will first flow into the first water channel 111 and be discharged from both sides of the first water channel 111. If the amount of leaked rainwater is too large, the amount of rainwater in the first water channel 111 exceeds the highest point of the first water channel 111, and the rainwater will overflow from the edge of the first water channel 111, reach the second water channel 121 below through the water channel 1112, and be collected by the second water channel 121. The second water guide groove 121 is in contact with the first frame 11 , and rainwater in the second water guide groove 121 can only be discharged through two sides of the second water guide groove 121 .

[0079] In some embodiments, a water-stopping protrusion 1111 facing the second water-conducting groove 121 is fixedly provided on the outer wall of the bottom of the first water-conducting groove 111 .

[0080] In order to prevent rainwater overflowing from the first water guide groove 111 from flowing directly along the bottom surface of the first water guide groove 111 to the gap formed between the first frame 11 and the second frame 12, thereby causing leakage, and to enable rainwater to flow more accurately into the second water guide groove 121, the water stop protrusion 1111 can block the flow path of rainwater.

[0081] In some embodiments, a plurality of water-stopping protrusions 1111 are provided. In addition, it is understood that, in some embodiments, the bottom outer wall of the first water guide groove 111 can also be set to be inclined, so that the end of the bottom outer wall of the first water guide groove 111 close to the first frame 11 is higher, which can also play a certain water-stopping effect, so that the rainwater overflowing from the first water guide groove 111 flows more accurately into the second water guide groove 121, further improving the water-conducting effect of the second water guide groove 121, thereby further improving the waterproof effect of the photovoltaic tile 1.

[0082] See also Figure 1 and Figure 2In some embodiments, the photovoltaic tile 1 further comprises a connection fitting, which is detachably mounted on the first frame 11 and the second frame 12 away from the side of the photovoltaic laminate 10, and the connection fitting is used to connect with the flat tile 2 adjacent to the photovoltaic tile 1, and / or the connection fitting is used to connect two adjacent photovoltaic tiles 1. The first frame 11 and the second frame 12 can selectively install different connection fittings, so that the photovoltaic tile 1 can be connected with the photovoltaic tile 1 or with the flat tile 2, without dismantling the entire roof, and can directly replace part of the existing flat tile 2 on the roof, thereby improving the standardization and compatibility of the photovoltaic tile 1, and can replace connection fittings of different sizes and types according to different usage scenarios, adapt to different overlap distance changes, and paving in non-standard positions, increase the effective paving area, and be suitable for paving with flat tiles 2 from different manufacturers. In addition, the photovoltaic paving structure equipped with the photovoltaic tile 1 has a small exposed area of ​​the profile and is more beautiful; through good integration with the traditional flat tile 2, the appearance of the building is unified and beautiful; it meets the roof tile system standard, can replace the roofing material, so that the roof can achieve power generation income, and improve the photovoltaic roof power generation income. Among them, roofing materials include tiles, asphalt rolls, metal sheets, concrete tiles, clay tiles, and cement tiles.

According to the different sizes and models of flat tiles 2 and photovoltaic tiles 1 that need to be overlapped, and according to different overlap distances, the first connection accessories 13 and the second connection accessories 14 of corresponding sizes and models can be installed on the first frame 11 and the second frame 12 to improve the flexibility of the use of the photovoltaic tile 1. For example, the first connection accessories 13 and the second connection accessories 14 of different widths (along the photovoltaic paving direction) can be replaced to adapt to the use.

[0086] In some embodiments, the first frame 11 , the second frame 12 , the first connecting fitting 13 and the second connecting fitting 14 can be aluminum profiles, so that the photovoltaic tile 1 has higher strength and lighter weight, and its weight is only about half of that of the traditional flat tile 2 .

The second frame 12 and the second connecting accessory 14 are detachably connected by snap-fitting between the second disassembly groove 122 and the second snap-fit ​​assembly.

When the second seal 16 needs to be disassembled from the second frame 12, the second clamping protrusion 18 and the second disassembly groove 122 are separated to separate the second seal 16 from the second frame 12.
