Description

Technical Field

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

[0002] Photovoltaic power generation is being used more and more widely in the building sector. Among them, photovoltaic tiles are a technology that combines solar energy utilization with roofing building materials. Workers lay photovoltaic tiles on the roof and use them to generate photovoltaic power to meet the needs of production and life.

[0003] In related technologies, multiple water-following strips and multiple purlins are installed on the roof of a building. The water-following strips are arranged at intervals along the length of the roof and each water-following strip extends along the slope of the roof. The length of the roof is perpendicular to the slope of the roof. The multiple purlins are arranged at intervals along the slope of the roof and each purlin extends along the length of the roof. The purlins are placed on the water-following strips. Multiple photovoltaic tiles are laid on the roof along the length and slope of the roof and installed on the purlins.

[0004] When a roof covered with photovoltaic tiles is exposed to wind and rain, the rainwater is difficult to drain effectively. It can easily enter the gap between the roof and the photovoltaic tiles through the gap between any two photovoltaic tiles arranged along the length of the building's roof, and damage the circuits located between the roof and the photovoltaic tiles. Utility Model Content

[0005] Therefore, it is necessary to provide a photovoltaic tile and photovoltaic tile system to address the problem that rainwater can easily enter the gap between the roof and the photovoltaic tile when the roof is currently covered with photovoltaic tiles.

[0006] A photovoltaic tile, comprising:

[0007] A laminate includes a first glass layer, a battery cell, and a second glass layer. The first glass layer includes a first overlapping portion and a first misaligned portion arranged along a first direction. The battery cell is disposed on one side of the first overlapping portion along a second direction. The second glass layer includes a second overlapping portion and a second misaligned portion arranged along the first direction. The second overlapping portion is disposed on the side of the battery cell opposite to the first overlapping portion, and the second misaligned portion is disposed on the side of the second overlapping portion opposite to the first misaligned portion. The first direction and the second direction intersect.

[0008] A sealing assembly includes a first sealing portion disposed on the side of the first misaligned portion close to the battery cell along the second direction.

[0009] In one embodiment, the first sealing portion and the battery cell are spaced apart along the first direction;

[0010] The sealing assembly includes a second sealing portion extending along the second direction. The second sealing portion is disposed on the side of the first sealing portion near the battery cell. One end of the second sealing portion contacts the side of the first misaligned portion near the battery cell along the second direction, and the other end is flush with the side of the second overlapping portion away from the battery cell.

[0011] In one embodiment, the photovoltaic tile includes a mounting frame disposed on the side of the second overlapping portion away from the solar cell, and the mounting frame is provided with a slot;

[0012] The second sealing part is provided with a hook, which engages with the slot.

[0013] In one embodiment, the mounting bracket extends along the first direction, and the side of the mounting bracket opposite to the second misaligned portion along the first direction contacts the side of the second sealing portion opposite to the first sealing portion along the first direction.

[0014] The mounting bracket has the slot on the side opposite to the second misaligned portion, and the second sealing portion has the hook on the side opposite to the first sealing portion along the first direction.

[0015] In one embodiment, an adhesive layer is provided between the second overlapping portion and the mounting bracket.

[0016] In one embodiment, the photovoltaic tile includes a support frame, the support frame including a first border;

[0017] The first frame is located on one side of the laminate along a third direction. Both the first direction and the second direction intersect with the third direction. The first frame has a groove on the side near the laminate, and the side of the laminate near the first frame is engaged in the groove.

[0018] In one embodiment, the first frame is provided with a mounting groove on the side away from the laminate along the third direction, the mounting groove being provided on the side of the groove along the second direction and spaced apart from the groove.

[0019] In one embodiment, the support frame includes a second frame, the second frame including a blocking portion and a supporting portion;

[0020] The blocking portion is disposed on the side of the laminate away from the first frame along the third direction, and the supporting portion is disposed on the side of the blocking portion along the second direction and contacts the side of the second glass layer away from the first glass layer.

[0021] In one embodiment, the laminate includes a plurality of the battery cells arranged in series, and the plurality of battery cells are spaced apart along the first direction.

[0022] In this embodiment, the photovoltaic tile has a first overlapping portion of the first glass layer and a second overlapping portion of the second glass layer overlapping along the thickness direction of the solar cell, while the first misaligned portion of the first glass layer and the second misaligned portion of the second glass layer do not overlap. This effectively offsets the first and second glass layers in the first direction. This allows workers to easily lay multiple photovoltaic tiles along the first direction by overlapping the first misaligned portion of one photovoltaic tile with the second misaligned portion of another. In any two adjacent photovoltaic tiles, a first gap is formed between the first misaligned portion of one photovoltaic tile and the first overlapping portion and second misaligned portion of the other, along with a second gap communicating with the first gap. This extends the gap between adjacent photovoltaic tiles, increasing the travel distance required for rainwater to enter the gap, increasing the resistance to rainwater movement within the gap between adjacent photovoltaic tiles, and reducing the risk of rainwater entering the gap between the roof and the photovoltaic tiles through any two adjacent photovoltaic tiles.

[0023] Furthermore, by placing the first sealing portion on the side of the first misaligned portion close to the solar cell along the second direction, it facilitates the sealing of the second gap between the first misaligned portion of one photovoltaic tile and the second misaligned portion of another photovoltaic tile when the first misaligned portion of one photovoltaic tile overlaps with the second misaligned portion of another photovoltaic tile. This prevents rainwater from entering the gap between the roof and the photovoltaic tile through the second gap after entering the first gap. In summary, when the photovoltaic tile in this embodiment is laid on the roof, rainwater is unlikely to enter the gap between the roof and the photovoltaic tile from the gap between two adjacent photovoltaic tiles, and it cannot damage the circuitry located between the roof and the photovoltaic tile.

[0024] This application also proposes a photovoltaic tile system, including the aforementioned photovoltaic tiles.

[0025] In this embodiment of the photovoltaic tile system, along the thickness direction of the solar cells, the first overlapping portion of the first glass layer and the second overlapping portion of the second glass layer overlap, while the first misaligned portion of the first glass layer and the second misaligned portion of the second glass layer do not overlap. This is equivalent to the first and second glass layers being staggered in the first direction. This facilitates the laying of multiple photovoltaic tiles along the first direction by overlapping the first misaligned portion of one photovoltaic tile with the second misaligned portion of another. Between the first misaligned portion of one photovoltaic tile and the first overlapping portion and second misaligned portion of the other photovoltaic tile in any two adjacent photovoltaic tiles, a first gap is formed, and a second gap communicating with the first gap is formed. This extends the gap between adjacent photovoltaic tiles, increasing the distance rainwater needs to travel after entering the gap, increasing the resistance to rainwater movement within the gap between adjacent photovoltaic tiles, and reducing the risk of rainwater entering the gap between the roof and the photovoltaic tiles through the gap between any two adjacent photovoltaic tiles.

[0026] Furthermore, by placing the first sealing portion on the side of the first misaligned portion close to the solar cell along the second direction, it facilitates the sealing of the second gap between the first misaligned portion of one photovoltaic tile and the second misaligned portion of another photovoltaic tile when the first misaligned portion of one photovoltaic tile overlaps with the second misaligned portion of another photovoltaic tile. This prevents rainwater from entering the gap between the roof and the photovoltaic tile through the second gap after entering the first gap. In summary, the photovoltaic tile system in this embodiment, when the photovoltaic tiles are laid on the roof, makes it difficult for rainwater to enter the gap between the roof and the photovoltaic tiles from the gap between two adjacent photovoltaic tiles, and it also prevents damage to the circuitry located between the roof and the photovoltaic tiles.

[0044] Please see Figures 1 to 3 , Figure 1This illustration shows a front view of a photovoltaic tile according to an embodiment of this application. An embodiment of this application provides a photovoltaic tile 1000, comprising: a laminate 1100 and a sealing assembly 1200. The laminate 1100 includes a first glass layer 1110, solar cells 1120, and a second glass layer 1130. The first glass layer 1110 includes a first overlapping portion 1111 and a first misaligned portion 1112 arranged along a first direction. The solar cells 1120 are disposed on one side of the first overlapping portion 1111 along a second direction. The second glass layer 1130 includes a first overlapping portion 1111 and a first misaligned portion 1112 arranged along the first direction. The second overlapping portion 1131 and the second misaligned portion 1132 of the fabric are provided. The second overlapping portion 1131 is provided on the side of the battery cell 1120 away from the first overlapping portion 1111, and the second misaligned portion 1132 is provided on the side of the second overlapping portion 1131 away from the first misaligned portion 1112. The first direction and the second direction are intersected. The sealing assembly 1200 includes a first sealing portion 1210, which is provided on the side of the first misaligned portion 1112 close to the battery cell 1120 along the second direction.

[0045] In this embodiment, the photovoltaic tile 1000, along the thickness direction of the solar cell 1120, has a first overlapping portion 1111 of the first glass layer 1110 and a second overlapping portion 1131 of the second glass layer 1130 overlapping, while the first misaligned portion 1112 of the first glass layer 1110 and the second misaligned portion 1132 of the second glass layer 1130 do not overlap. This is equivalent to the first glass layer 1110 and the second glass layer 1130 being arranged in a staggered manner in the first direction. This allows workers to easily lay multiple photovoltaic tiles 1000 along the first direction by overlapping the first misaligned portion 1112 of one photovoltaic tile 1000 with the second misaligned portion 1132 of another photovoltaic tile 1000. In any two adjacent photovoltaic tiles 1000, a first gap (not shown) and a second gap (not shown) communicating with the first gap are formed between the first misaligned portion 1112 of one photovoltaic tile 1000 and the first overlapping portion 1111 and the second misaligned portion 1132 of the other photovoltaic tile 1000, respectively. This extends the gap between two adjacent photovoltaic tiles 1000, increases the travel distance required for rainwater to enter the gap, increases the resistance to rainwater movement in the gap between two adjacent photovoltaic tiles 1000, and reduces the risk of rainwater entering the gap between the roof and the photovoltaic tiles 1000 through the gap between any two adjacent photovoltaic tiles 1000.

[0046] Furthermore, by placing the first sealing part 1210 on the side of the first misaligned part 1112 close to the solar cell 1120 along the second direction, it facilitates the sealing of the second gap between the first misaligned part 1112 of one photovoltaic tile 1000 and the second misaligned part 1132 of another photovoltaic tile 1000 when the worker overlaps them. This prevents rainwater from entering the gap between the roof and the photovoltaic tile 1000 after entering the first gap, and then entering the gap between the roof and the photovoltaic tile 1000 through the second gap. In summary, when the photovoltaic tile 1000 in this embodiment is laid on the roof, rainwater is unlikely to enter the gap between the roof and the photovoltaic tile 1000 from the gap between two adjacent photovoltaic tiles 1000, and cannot damage the circuit located between the roof and the photovoltaic tile 1000.

[0047] Please see Figure 1 In some embodiments, the first sealing portion 1210 and the battery cell 1120 are spaced apart along a first direction. The sealing assembly 1200 includes a second sealing portion 1220, which extends along a second direction. The second sealing portion 1220 is disposed on the side of the first sealing portion 1210 near the battery cell 1120. One end of the second sealing portion 1220 contacts the side of the first misaligned portion 1112 near the battery cell 1120 along the second direction, and the other end is flush with the side of the second overlapping portion 1131 away from the battery cell 1120.

[0048] In this embodiment, a second sealing part 1220 is provided on the side of the first sealing part 1210 near the solar cell 1120. One end of the second sealing part 1220 contacts the side of the first misaligned part 1112 near the solar cell 1120 along the second direction, and the other end is flush with the side of the second overlapping part 1131 away from the solar cell 1120. This allows workers to block the gap between the second overlapping part 1131 of one photovoltaic tile 1000 and the second misaligned part 1132 of another photovoltaic tile 1000 when the first misaligned part 1112 of one photovoltaic tile 1000 is overlapped with the second misaligned part 1132 of another photovoltaic tile 1000 by the second sealing part 1220, preventing rainwater from entering the gap between the roof and the photovoltaic tile 1000 through the gap.

[0049] In some embodiments, the orthographic projection of the first overlapping portion 1111 onto the battery cell 1120 overlaps with the orthographic projection of the second overlapping portion 1131 onto the battery cell 1120.

[0050] Please see Figures 1 to 3In some embodiments, the photovoltaic tile 1000 includes a mounting bracket 1300, which is disposed on the side of the second overlapping portion 1131 away from the solar cell 1120. The mounting bracket 1300 is provided with a slot 1310, and the second sealing portion 1220 is provided with a hook 1230, which engages with the slot 1310.

[0051] In this embodiment, both the first sealing part 1210 and the first sealing part 1210 are engaged with the slot 1310 on the mounting bracket 1300 by means of the hook 1230.

[0052] Please see Figures 1 to 3 In some embodiments, the mounting bracket 1300 extends along a first direction, and the side of the mounting bracket 1300 away from the second misaligned portion 1132 along the first direction contacts the side of the second sealing portion 1220 away from the first sealing portion 1210 along the first direction. The side of the mounting bracket 1300 away from the second misaligned portion 1132 is provided with a slot 1310, and the side of the second sealing portion 1220 away from the first sealing portion 1210 along the first direction is provided with a hook 1230.

[0053] In this embodiment, the mounting bracket 1300 contacts the side of the second sealing portion 1220 opposite to the second misaligned portion 1132 along the first direction and the side of the second sealing portion 1220 opposite to the first sealing portion 1210 along the first direction, so as to block the gap between the second sealing portion 1220 and the second overlapping portion 1131, and prevent rainwater from entering the battery cell 1120 between the first overlapping portion 1111 and the second overlapping portion 1131 through the gap between the second sealing portion 1220 and the second overlapping portion 1131, thereby avoiding damage to the battery cell 1120 by rainwater.

[0054] Please see Figures 1 to 3 In some embodiments, an adhesive layer (not shown) is provided between the second overlapping portion 1131 and the mounting bracket 1300.

[0055] In this embodiment, by providing an adhesive layer, it is easy to achieve a detachable connection between the mounting bracket 1300 and the second overlapping portion 1131.

[0056] Please see Figures 1 to 3 In some embodiments, the photovoltaic tile 1000 includes a support frame 1400, the support frame 1400 includes a first frame 1410, the first frame 1410 is located on one side of the laminate 1100 along a third direction, the first direction and the second direction are both intersecting with the third direction, the first frame 1410 is provided with a groove 1411 on the side of the first frame 1410 near the laminate 1100, and the side of the laminate 1100 near the first frame 1100 is engaged in the groove 1411.

[0057] In this embodiment, by setting the laminate 1100 to engage with the groove 1411 on the first frame 1410, it is convenient for workers to disassemble or assemble the laminate 1100 and the first frame 1410.

[0058] In some embodiments, the first frame 1410 is made of aluminum alloy.

[0059] Please see Figures 1 to 3 In some embodiments, the first frame 1410 is provided with a mounting groove 1412 on the side away from the laminate 1100 along a third direction. The mounting groove 1412 is provided on the side of the groove 1411 along the second direction and is spaced apart from the groove 1411.

[0060] In this embodiment, by setting the mounting groove 1412, the workers can use the mounting groove 1412 to engage with the purlins of the roof to assemble the first frame 1410 with the purlins of the roof, thereby realizing the installation of photovoltaic tiles 1000 on the roof.

[0061] Please see Figures 1 to 3 In some embodiments, the support frame 1400 includes a second frame 1420, which includes a blocking portion 1421 and a support portion 1422. The blocking portion 1421 is disposed on the side of the laminate 1100 away from the first frame 1410 along a third direction, and the support portion 1422 is disposed on the side of the blocking portion 1421 along a second direction and contacts the side of the second glass layer 1130 away from the first glass layer 1110.

[0062] Compared to the traditional method where "the photovoltaic tile 1000 is surrounded by a frame (not shown), and each edge of the photovoltaic tile 1000 is snapped into the corresponding frame", the frame blocks the sunlight from shining on the photovoltaic tile 1000. The area on the photovoltaic tile 1000 that can receive light is smaller, resulting in a lower battery filling rate and lower photoelectric conversion efficiency.

[0063] In this embodiment, the support frame 1400 includes a first frame 1410 and a second frame 1420. The second frame 1420 includes a blocking part 1421 and a supporting part 1422. The blocking part 1421 is disposed on the side of the laminate 1100 away from the first frame 1410 along a third direction, and the supporting part 1422 is disposed on the side of the blocking part 1421 along a second direction and contacts the side of the second glass layer 1130 away from the first glass layer 1110. This ensures that the support frame 1400 only blocks sunlight from shining on the laminate 1100 along the third direction. In other words, the sunlight... Of all the light rays that illuminate the laminate 1100, only the portion of the light rays illuminating the laminate 1100 along the third direction is blocked by the support frame 1400. All the remaining light rays pass through the first glass layer 1110 in the laminate 1100 and are absorbed by the solar cells 1120. This arrangement reduces the obstruction of sunlight from the support frame 1400 to the laminate 1100, thereby increasing the area of ​​the laminate 1100 that can receive light. This makes it easier for workers to increase the fill rate of the solar cells 1120 in the photovoltaic tile 1000, and thus improves the photoelectric conversion efficiency of the photovoltaic tile 1000.

[0064] In some embodiments, the second frame 1420 is made of aluminum alloy.

[0065] In some embodiments, the photovoltaic tile 1000 includes a water-blocking strip 1500, which extends along a second direction and is located on the side of the support portion 1422 opposite to the second glass layer 1130 and is engaged with the support portion 1422. The water-blocking strip 1500 is capable of swinging relative to the support portion 1422 along a third direction.

[0066] Please see Figures 1 to 3 In some embodiments, the laminate 1100 includes a plurality of battery cells 1120 arranged in series, and the plurality of battery cells 1120 are spaced apart along a first direction.

[0067] In this embodiment, by connecting multiple solar cells 1120 in series, the power generation of the photovoltaic tile 1000 can be increased.

[0068] In some embodiments, the solar cell 1120 may be a common type of solar cell capable of photoelectric conversion, such as a monocrystalline silicon cell, a polycrystalline silicon cell, or a tandem cell.

[0069] In some embodiments, the length and width of the battery cell 1120 can be 210mm*105mm or 182mm*105mm.

[0070] In some embodiments, the dimensions of the photovoltaic tile 1000 along the first direction are between 505mm and 1780mm.

[0071] In some embodiments, a group of battery cells 1120 arranged at intervals along a first direction and connected in series are defined as a battery string, and multiple battery strings are arranged in parallel and arranged at intervals along a third direction.

[0072] In some embodiments, the dimensions of the photovoltaic tile 1000 along a third direction are between 260mm and 500mm.

[0073] This application also proposes a photovoltaic tile system (not shown) including the aforementioned photovoltaic tile 1000.

[0074] In this embodiment of the photovoltaic tile system, along the thickness direction of the solar cell 1120, the first overlapping portion 1111 of the first glass layer 1110 and the second overlapping portion 1131 of the second glass layer 1130 overlap, while the first misaligned portion 1112 of the first glass layer 1110 and the second misaligned portion 1132 of the second glass layer 1130 do not overlap. This is equivalent to the first glass layer 1110 and the second glass layer 1130 being arranged in a staggered manner in the first direction. This allows workers to easily lay multiple photovoltaic tiles 1000 along the first direction by overlapping the first misaligned portion 1112 of one photovoltaic tile 1000 with the second misaligned portion 1132 of another photovoltaic tile 1000. In any two adjacent photovoltaic tiles 1000, a first gap is formed between the first misaligned portion 1112 of one photovoltaic tile 1000 and the first overlapping portion 1111 and the second misaligned portion 1132 of the other photovoltaic tile 1000, and a second gap communicating with the first gap. This extends the gap between two adjacent photovoltaic tiles 1000, increases the travel distance required for rainwater to enter the gap, increases the resistance to rainwater movement in the gap between two adjacent photovoltaic tiles 1000, and reduces the risk of rainwater entering the gap between the roof and the photovoltaic tiles 1000 through the gap between any two adjacent photovoltaic tiles 1000.

[0075] Furthermore, by placing the first sealing part 1210 on the side of the first misaligned part 1112 close to the solar cell 1120 along the second direction, it facilitates the sealing of the second gap between the first misaligned part 1112 of one photovoltaic tile 1000 and the second misaligned part 1132 of another photovoltaic tile 1000 when the workers overlap the first misaligned part 1112 of one photovoltaic tile 1000 and the second misaligned part 1132 of another photovoltaic tile 1000. This prevents rainwater from entering the first gap and then entering the gap between the roof and the photovoltaic tile 1000 through the second gap. In summary, in this embodiment of the photovoltaic tile system, when the photovoltaic tiles 1000 are laid on the roof, rainwater is unlikely to enter the gap between the roof and the photovoltaic tile 1000 from the gap between two adjacent photovoltaic tiles 1000, and cannot damage the circuit located between the roof and the photovoltaic tile 1000.

[0076] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0077] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
