Description

Technical Field

[0001] The utility model relates to the technical field of photovoltaic equipment, in particular to a photovoltaic tile. Background Art

[0002] At present, when photovoltaic tiles in related technologies are installed on roofs and other buildings, the overlapping edges of the photovoltaic tiles have poor waterproofing ability, which affects the service life of the photovoltaic tiles. Utility Model Content

[0003] The embodiments of the utility model are intended to solve at least one of the technical problems existing in the prior art.

[0004] To this end, a first aspect of an embodiment of the utility model provides a photovoltaic tile.

[0005] In view of this, according to the first aspect of an embodiment of the utility model, a photovoltaic tile is provided, which includes: a photovoltaic panel, which can convert light energy into electrical energy; a first joint and a second joint, which are arranged on the photovoltaic panel and are respectively located on opposite sides of the photovoltaic panel, and in two adjacent photovoltaic tiles, the first joint of one photovoltaic tile is matched and connected with the second joint of the other photovoltaic tile; wherein, at least one of the first joint and the second joint is provided with at least two drainage grooves, and at least one drainage groove is connected to the outside.

[0006] The photovoltaic tile provided by the embodiment of the utility model includes a photovoltaic panel, a first lap joint and a second lap joint. Specifically, the first lap joint and the second lap joint are arranged on the photovoltaic panel, and the first lap joint and the second lap joint are respectively located on two opposite sides of the photovoltaic panel. Optionally, the first lap joint and the second lap joint are respectively located on two sides in the length direction of the photovoltaic panel. Alternatively, the first lap joint and the second lap joint are respectively located on two sides in the width direction of the photovoltaic panel. The specific arrangement can be made according to actual needs.

[0007] In two adjacent photovoltaic tiles, the first lap joint of one photovoltaic tile is connected with the second lap joint of the other photovoltaic tile, that is, for one photovoltaic tile, one side of the photovoltaic tile is connected with the second lap joint of the adjacent photovoltaic tile through the first lap joint, and the other side of the photovoltaic tile is connected with the first lap joint of the other adjacent photovoltaic tile through the second lap joint. This achieves reliable fixation of the opposite sides of the photovoltaic panel and improves the load resistance of multiple photovoltaic tiles after being installed on the building.

[0008] At least one of the first bridging member and the second bridging member is provided with at least two drainage grooves, specifically, the first bridging member is provided with at least two drainage grooves. Alternatively, the second bridging member is provided with at least two drainage grooves. Alternatively, both the first bridging member and the second bridging member are provided with at least two drainage grooves. The specific configuration can be based on actual needs.

[0009] That is to say, a drainage groove is set at the overlap of adjacent photovoltaic tiles, and the drainage groove is connected to the outside, so that the water that penetrates into the drainage groove can be discharged in time, improving the waterproof performance of the overlap of adjacent photovoltaic tiles and extending the service life of photovoltaic tiles. It is also beneficial to reduce the probability of failure of photovoltaic tiles, thereby reducing the maintenance cost of photovoltaic tiles.

[0010] There are at least two drainage grooves, which can ensure the waterproof effect of the overlap of adjacent photovoltaic tiles even when a large amount of water seeps in, further enhance the waterproof performance of the overlap of adjacent photovoltaic tiles, improve the waterproof function of the photovoltaic system with multiple photovoltaic tiles, reduce the probability of failure of photovoltaic tiles, and thus reduce the maintenance cost of photovoltaic tiles.

[0011] Optionally, at least two drainage grooves are arranged along the length direction of the photovoltaic panel.

[0012] In addition, the photovoltaic tile provided according to the above technical solution of the utility model also has the following additional technical features:

[0013] In some technical solutions, optionally, the first lap joint and the second lap joint are located on both sides of the photovoltaic panel in the length direction, and at least one drainage groove extends along the width direction of the photovoltaic panel.

[0014] In this technical solution, the first overlap member and the second overlap member are located on both sides of the photovoltaic panel in the length direction, that is, adjacent photovoltaic tiles are overlapped in sequence along the horizontal direction, that is, in a row of multiple photovoltaic tiles, adjacent photovoltaic tiles are overlapped in sequence.

[0015] Specifically, in a row of photovoltaic tiles, multiple photovoltaic tiles include adjacent first photovoltaic tiles and second photovoltaic tiles, wherein the first overlap piece on the first photovoltaic tile is cooperatively connected with the second overlap piece on the second photovoltaic tile, and the second overlap piece on the first photovoltaic tile is cooperatively connected with the first overlap piece on another photovoltaic tile adjacent to the first photovoltaic tile in the horizontal direction.

[0016] At least one drainage groove extends along the width direction of the photovoltaic panel, that is, at least one drainage groove extends along the arrangement direction of a row of photovoltaic tiles. It is understandable that after a plurality of photovoltaic tiles are installed on a roof or other building, there is a height difference between two adjacent photovoltaic tiles in a row of a plurality of photovoltaic tiles, that is, a plurality of photovoltaic tiles in a row are arranged in sequence from bottom to top, or from top to bottom, that is, when the photovoltaic tiles are installed on the roof, at least one drainage groove is tilted, which is conducive to the rapid discharge of water infiltrated into the drainage groove, improves the waterproof performance of the overlap of two adjacent photovoltaic tiles in a row of photovoltaic tiles, and makes the photovoltaic system with a plurality of photovoltaic tiles have a stronger waterproof function.

[0017] In some technical solutions, optionally, when the first joint is provided with at least two drainage grooves, the first joint is also provided with a joint groove, which is connected to at least one drainage groove; the second joint is provided with a joint portion, and at least a portion of the joint portion is located in the joint groove of adjacent photovoltaic tiles.

[0018] In this technical solution, it is defined that when the first joint is provided with at least two drainage grooves, the first joint is also provided with a joint groove, and the second joint is provided with a joint portion. Specifically, at least a portion of the joint portion is located in the joint groove of adjacent photovoltaic tiles, thereby achieving overlap between adjacent photovoltaic tiles, improving the installation and disassembly efficiency of photovoltaic tiles, and facilitating later maintenance.

[0019] The overlapping groove is connected to at least one drainage groove. It can be understood that the location of the overlapping groove is the overlapping part of adjacent photovoltaic tiles. That is to say, even if a certain amount of water seeps into the overlapping part of adjacent photovoltaic tiles, this part of water will flow into at least one drainage groove and be discharged through at least one drainage groove, thereby further improving the waterproof performance of the overlapping part of adjacent photovoltaic tiles and enhancing the waterproof ability of the entire photovoltaic system.

[0020] In some technical solutions, optionally, the first overlap member is also provided with a first overlap surface, and the first overlap surface is located in the overlap groove; a second overlap surface is provided on the backlight side of the overlap portion, and when at least a portion of the overlap portion is located in the overlap groove of the adjacent photovoltaic tile, the second overlap surface is in contact with the first overlap surface of the adjacent photovoltaic tile.

[0021] In this technical solution, it is defined that the first overlapping member is also provided with a first overlapping surface. Specifically, the first overlapping surface is located in the overlapping groove.

[0022] A second overlapping surface is provided on the backlight side of the overlapping portion. Specifically, when at least a portion of the overlapping portion is located in the overlapping groove of the adjacent photovoltaic tile, the second overlapping surface is in contact with the first overlapping surface in the overlapping groove. That is to say, among two adjacent photovoltaic tiles, the first overlapping piece of one photovoltaic tile and the second overlapping piece of the other photovoltaic tile have a certain overlapping area, forming a first line of waterproofing. It can be understood that when water seeps through the first overlapping surface and the second overlapping surface, it will enter into at least two drainage grooves, that is, at least two drainage grooves are the second line of waterproofing.

[0023] By adding two waterproof structures at the overlap of adjacent photovoltaic tiles, the waterproof function of the overlap of adjacent photovoltaic tiles can be significantly enhanced, thereby improving the waterproof ability of the entire photovoltaic system and extending the service life of the photovoltaic tiles.

[0024] It can be understood that, since the second overlapping surface is located on the backlight side of the overlapping portion, in order to fit with the second overlapping surface, the first overlapping surface is located on the light-receiving side of the first overlapping member.

[0025] In some technical solutions, optionally, along the length direction of the photovoltaic panel, the width of the first overlapping surface is smaller than the width of the drainage groove connected to the overlapping groove.

[0026] In this technical solution, along the length direction of the photovoltaic panel, the width of the first overlapping surface is smaller than the width of the drainage groove connected to the overlapping groove, so that even if water seeps into between the first overlapping surface and the second overlapping surface, the seeped water will flow into the drainage groove connected to the overlapping groove and be discharged through the drainage groove.

[0027] That is to say, by limiting the width of the first overlapping surface to be smaller than the width of the drainage groove connected to the overlapping groove, water that penetrates between the first overlapping surface and the second overlapping surface can flow into the drainage groove, further improving the waterproof performance of the overlapping area of ​​adjacent photovoltaic tiles.

[0028] In some technical solutions, optionally, the first lap joint is further provided with a limiting surface, which is connected to the first lap joint surface and enclosed with the first lap joint surface to form a lap joint groove; a side of the lap joint portion facing away from the photovoltaic panel is in contact with the limiting surface of the adjacent photovoltaic tile.

[0029] In this technical solution, the first lap joint is further provided with a limiting surface, specifically, the limiting surface is connected to the first lap joint surface, and the limiting surface and the first lap joint surface enclose a lap joint groove. It can be understood that the limiting surface is located on the side of the first lap joint away from the photovoltaic panel.

[0030] The side of the overlap portion facing away from the photovoltaic panel is in contact with the limiting surface of the adjacent photovoltaic tile, which can improve the waterproof effect of the first waterproofing line, thereby further enhancing the waterproof function of the overlap of adjacent photovoltaic tiles, and then enhancing the waterproof performance of the entire photovoltaic system and extending the service life of the photovoltaic tiles.

[0031] In some technical solutions, optionally, when the first connecting piece is provided with at least two drainage grooves, the backlight side of the second connecting piece is further provided with a limiting portion, and the limiting portion is inserted into at least one drainage groove of adjacent photovoltaic tiles.

[0032] In this technical solution, it is stipulated that when the first joint is provided with at least two drainage grooves, a limiting portion is also provided on the backlight side of the second joint, and the limiting portion is inserted into at least one drainage groove of adjacent photovoltaic tiles, thereby forming a limit between adjacent photovoltaic tiles in the length direction of the photovoltaic tiles, thereby improving the installation stability of the photovoltaic tiles and further improving the load resistance performance of the photovoltaic tiles.

[0033] Optionally, the number of the limiting parts is at least two, and the at least two limiting parts are respectively inserted into at least two drainage grooves to further improve the connection strength between adjacent photovoltaic tiles and enhance the installation reliability of the photovoltaic tiles.

[0034] In some technical schemes, optionally, the first joint includes a first body and a plug-in portion, wherein the first body is connected to one end of the photovoltaic panel, the plug-in portion is arranged on the light-receiving side of the first body, and is combined with the first body to form at least two drainage grooves; the second joint also includes a second body, the second body is connected to the other end of the photovoltaic panel, the limiting portion is arranged on the backlight side of the second body, and is combined with the second body to form a plug-in groove, and the plug-in portion is inserted into the plug-in groove of an adjacent photovoltaic tile.

[0035] In this technical solution, it is defined that the first connecting piece includes a first body and a plug-in portion. Specifically, the first body is connected to one end of the photovoltaic panel, the plug-in portion is arranged on the light-receiving side of the first body, and the plug-in portion and the first body are enclosed to form at least two drainage grooves.

[0036] The second connecting piece includes a second body. Specifically, the second body is connected to the other end of the photovoltaic panel. That is to say, the first body and the second body are respectively connected to the two opposite ends of the photovoltaic panel.

[0037] The limiting portion is arranged on the backlight side of the second body, and the limiting portion and the second body are combined to form a plug-in groove. Among two adjacent photovoltaic tiles, the plug-in portion of one photovoltaic tile is inserted into the plug-in groove of the other photovoltaic tile, and the limiting portion of the other photovoltaic tile is inserted into at least one drainage groove of the photovoltaic tile, forming an interlocking structure. This can ensure the waterproof performance of the overlapping parts of adjacent photovoltaic tiles while further improving the connection strength of adjacent photovoltaic tiles, preventing adjacent photovoltaic tiles from separating in the length direction of the photovoltaic panel, improving the installation stability of the photovoltaic tiles, and thereby improving the load resistance of the photovoltaic tiles.

[0038] Optionally, when there are at least two limiting parts, at least two limiting parts and the second body form at least two plug-in grooves, and when there are at least two plug-in parts, at least two plug-in grooves are respectively inserted into at least two plug-in grooves of adjacent photovoltaic tiles.

[0039] Optionally, the first body and the plug-in portion are an integrated structure.

[0040] Optionally, the second body and the limiting portion are an integrated structure.

[0042] In this technical solution, it is defined that the photovoltaic tile also includes a first adhesive component. Specifically, a first mounting groove is provided on the side of the first body facing the photovoltaic panel. One end of the photovoltaic panel is inserted into the first mounting groove and connected to the first body through the first adhesive component. Thus, while achieving reliable assembly between the first adhesive component and the photovoltaic panel, the surface of the photovoltaic panel will not be damaged, thereby improving the aesthetics of the photovoltaic tile.

[0043] Optionally, the first adhesive component includes a flexible component, that is, there is a flexible component between the inner wall of the first installation groove and the photovoltaic panel, thereby avoiding rigid contact between the first lap joint and the photovoltaic panel during the installation process and damaging the photovoltaic panel, and also improving the impact resistance of the first lap joint and the photovoltaic panel installation position.

[0044] In some technical solutions, optionally, a second mounting groove is provided on the side of the second body facing the photovoltaic panel, and the other end of the photovoltaic panel is inserted into the second mounting groove; the photovoltaic tile also includes a second adhesive, the second adhesive is provided in the second mounting groove, and the second body is connected to the other end of the photovoltaic panel through the second adhesive.

[0057] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0058] Refer to the following Figures 1 to 4 The photovoltaic tile 100 provided according to some embodiments of the present invention is described.

[0059] In one embodiment according to the present application, Figure 1 and Figure 2As shown, a photovoltaic tile 100 is proposed, and the photovoltaic tile 100 includes: a photovoltaic panel 110, and the photovoltaic panel 110 can convert light energy into electrical energy; a first joint 120 and a second joint 130, which are arranged on the photovoltaic panel 110 and are respectively located on opposite sides of the photovoltaic panel 110, and in two adjacent photovoltaic tiles 100, the first joint 120 of one photovoltaic tile 100 is matched and connected with the second joint 130 in the other photovoltaic tile 100; wherein, at least one of the first joint 120 and the second joint 130 is provided with at least two drainage grooves 140, and at least one of the drainage grooves 140 is connected to the outside.

[0060] The photovoltaic tile 100 provided in the embodiment of the utility model includes a photovoltaic panel 110, a first bridging member 120 and a second bridging member 130. Specifically, the first bridging member 120 and the second bridging member 130 are arranged on the photovoltaic panel 110, and the first bridging member 120 and the second bridging member 130 are respectively located on two opposite sides of the photovoltaic panel 110. Optionally, the first bridging member 120 and the second bridging member 130 are respectively located on two sides in the length direction of the photovoltaic panel 110. Alternatively, the first bridging member 120 and the second bridging member 130 are respectively located on two sides in the width direction of the photovoltaic panel 110. The specific arrangement can be made according to actual needs.

[0061] In two adjacent photovoltaic tiles 100, the first bridging piece 120 of one photovoltaic tile 100 is connected with the second bridging piece 130 of the other photovoltaic tile 100, that is, for one photovoltaic tile 100, one side of the photovoltaic tile 100 is connected with the second bridging piece 130 of the adjacent photovoltaic tile 100 through the first bridging piece 120, and the other side of the photovoltaic tile 100 is connected with the first bridging piece 120 of the other adjacent photovoltaic tile 100 through the second bridging piece 130. Thus, the two opposite sides of the photovoltaic panel 110 are reliably fixed, and the load resistance performance of multiple photovoltaic tiles 100 after being installed on the building is improved.

[0062] At least one of the first bridging member 120 and the second bridging member 130 is provided with at least two drainage grooves 140. Specifically, the first bridging member 120 is provided with at least two drainage grooves 140. Alternatively, the second bridging member 130 is provided with at least two drainage grooves 140. Alternatively, the first bridging member 120 and the second bridging member 130 are both provided with at least two drainage grooves 140. The configuration can be made according to actual needs.

[0063] That is to say, a drainage groove 140 is provided at the overlap of adjacent photovoltaic tiles 100, and the drainage groove 140 is connected to the outside, so that water infiltrated into the drainage groove 140 can be discharged in time, thereby improving the waterproof performance of the overlap of adjacent photovoltaic tiles 100 and extending the service life of the photovoltaic tiles 100. It is also beneficial to reduce the probability of failure of the photovoltaic tiles 100, thereby reducing the maintenance cost of the photovoltaic tiles 100.

[0064] There are at least two drainage grooves 140. Even when a large amount of water seeps in, the waterproof effect of the overlapping joints of adjacent photovoltaic tiles 100 can be ensured, further enhancing the waterproof performance of the overlapping joints of adjacent photovoltaic tiles 100, improving the waterproof function of the photovoltaic system with multiple photovoltaic tiles 100, reducing the probability of failure of the photovoltaic tiles 100, and thereby reducing the maintenance cost of the photovoltaic tiles 100.

[0065] Optionally, at least two drainage grooves 140 are arranged along the length direction of the photovoltaic panel 110 .

[0066] like Figure 2 As shown, in some embodiments, optionally, the first lap joint 120 and the second lap joint 130 are located on both sides of the photovoltaic panel 110 in the length direction, and at least one drainage groove 140 extends along the width direction of the photovoltaic panel 110 .

[0067] In this embodiment, the first overlap member 120 and the second overlap member 130 are located on both sides of the photovoltaic panel 110 in the length direction, that is, adjacent photovoltaic tiles 100 are overlapped in sequence along the horizontal direction, that is, in a row of multiple photovoltaic tiles 100, adjacent photovoltaic tiles 100 are overlapped in sequence.

[0068] Specifically, in a row of photovoltaic tiles 100, multiple photovoltaic tiles 100 include adjacent first photovoltaic tiles and second photovoltaic tiles, wherein the first connector 120 on the first photovoltaic tile is cooperatively connected with the second connector 130 on the second photovoltaic tile, and the second connector 130 on the first photovoltaic tile is cooperatively connected with the first connector 120 on another photovoltaic tile 100 adjacent to the first photovoltaic tile in the horizontal direction.

[0069] At least one drainage groove 140 extends along the width direction of the photovoltaic panel 110, that is, at least one drainage groove 140 extends along the arrangement direction of a row of photovoltaic tiles 100. It can be understood that after a plurality of photovoltaic tiles 100 are installed on a roof or other building, there is a height difference between two adjacent photovoltaic tiles 100 in a row of a plurality of photovoltaic tiles 100, that is, a plurality of photovoltaic tiles 100 in a row are arranged in sequence from bottom to top, or from top to bottom, that is, when the photovoltaic tiles 100 are installed on the roof, at least one drainage groove 140 is tilted, so as to facilitate the rapid discharge of water infiltrated into the drainage groove 140, improve the waterproof performance of the overlap of two adjacent photovoltaic tiles 100 in a row of photovoltaic tiles 100, and make the photovoltaic system with a plurality of photovoltaic tiles 100 have a stronger waterproof function.

[0070] like Figure 1 , Figure 3 and Figure 4As shown, in some embodiments, optionally, when the first joint 120 is provided with at least two drainage grooves 140, the first joint 120 is also provided with a joint groove 121, and the joint groove 121 is connected to at least one drainage groove 140; the second joint 130 is provided with a joint portion 131, and at least a portion of the joint portion 131 is located in the joint groove 121 of the adjacent photovoltaic tile 100.

[0071] In this embodiment, it is defined that when the first joint 120 is provided with at least two drainage grooves 140, the first joint 120 is also provided with a overlapping groove 121, and the second joint 130 is provided with a overlapping portion 131. Specifically, at least a portion of the overlapping portion 131 is located in the overlapping groove 121 of adjacent photovoltaic tiles 100, thereby achieving overlap between adjacent photovoltaic tiles 100, improving the installation and disassembly efficiency of the photovoltaic tiles 100, and facilitating later maintenance.

[0072] The overlapping groove 121 is connected to at least one drainage groove 140. It can be understood that the location of the overlapping groove 121 is the overlapping part of adjacent photovoltaic tiles 100. That is to say, even if a certain amount of water seeps into the overlapping part of adjacent photovoltaic tiles 100, this part of water will flow into at least one drainage groove 140 and be discharged through at least one drainage groove 140, thereby further improving the waterproof performance of the overlapping part of adjacent photovoltaic tiles 100 and enhancing the waterproof ability of the entire photovoltaic system.

[0073] like Figure 3 and Figure 4 As shown, in some embodiments, optionally, the first lap joint 120 is also provided with a first lap joint surface 122, and the first lap joint surface 122 is located in the lap joint groove 121; a second lap joint surface 132 is provided on the backlight side of the lap joint portion 131, and when at least a portion of the lap joint portion 131 is located in the lap joint groove 121 of the adjacent photovoltaic tile 100, the second lap joint surface 132 is in contact with the first lap joint surface 122 of the adjacent photovoltaic tile 100.

[0074] In this embodiment, it is defined that the first lap joint 120 is further provided with a first lap joint surface 122 . Specifically, the first lap joint surface 122 is located in the lap joint groove 121 .

[0075] A second overlapping surface 132 is provided on the backlight side of the overlapping portion 131. Specifically, when at least a portion of the overlapping portion 131 is located in the overlapping groove 121 of the adjacent photovoltaic tile 100, the second overlapping surface 132 is in contact with the first overlapping surface 122 in the overlapping groove 121. That is to say, among two adjacent photovoltaic tiles 100, the first overlapping member 120 of one photovoltaic tile 100 and the second overlapping member 130 of the other photovoltaic tile 100 have a certain overlapping area, forming a first line of waterproofing. It can be understood that when water penetrates through the first overlapping surface 122 and the second overlapping surface 132, it will enter into at least two drainage grooves 140, that is, at least two drainage grooves 140 are the second line of waterproofing.

[0076] By adding two waterproof structures at the overlap of adjacent photovoltaic tiles 100 , the waterproof function of the overlap of adjacent photovoltaic tiles 100 can be significantly enhanced, thereby improving the waterproof ability of the entire photovoltaic system and extending the service life of the photovoltaic tiles 100 .

[0077] It is understandable that, since the second overlapping surface 132 is located on the backlight side of the overlapping portion 131 , the first overlapping surface 122 is located on the light-receiving side of the first overlapping member 120 in order to fit with the second overlapping surface 132 .

[0078] like Figure 3 As shown, in some embodiments, optionally, along the length direction of the photovoltaic panel 110 , the width of the first overlapping surface 122 is smaller than the width of the drainage groove 140 connected to the overlapping groove 121 .

[0079] In this embodiment, along the length direction of the photovoltaic panel 110, the width of the first lap joint 122 is smaller than the width of the drainage groove 140 connected to the lap groove 121, so that even if water seeps into between the first lap joint 122 and the second lap joint 132, the seeped water will flow into the drainage groove 140 connected to the lap groove 121 and be discharged through the drainage groove 140.

[0080] That is to say, by limiting the width of the first overlapping surface 122 to be smaller than the width of the drainage groove 140 connected to the overlapping groove 121, it is possible to facilitate water that penetrates between the first overlapping surface 122 and the second overlapping surface 132 to flow into the drainage groove 140, thereby further improving the waterproof performance of the overlapping points of adjacent photovoltaic tiles 100.

[0081] like Figure 3 As shown, in some embodiments, optionally, the first lap joint 120 is also provided with a limiting surface 123, which is connected to the first lap joint surface 122 and encloses the first lap joint surface 122 to form a lap groove 121; the side of the lap joint 131 facing away from the photovoltaic panel 110 is in contact with the limiting surface 123 of the adjacent photovoltaic tile 100.

[0082] In this embodiment, the first lap joint 120 is further provided with a limiting surface 123. Specifically, the limiting surface 123 is connected to the first lap joint surface 122, and the limiting surface 123 and the first lap joint surface 122 are enclosed to form a lap joint groove 121. It can be understood that the limiting surface 123 is located on the side of the first lap joint 120 away from the photovoltaic panel 110.

[0083] The side of the overlapping portion 131 facing away from the photovoltaic panel 110 is in contact with the limiting surface 123 of the adjacent photovoltaic tile 100, which can improve the waterproof effect of the first waterproofing, thereby further enhancing the waterproof function of the overlapping portion of the adjacent photovoltaic tiles 100, and further enhancing the waterproof performance of the entire photovoltaic system, thereby extending the service life of the photovoltaic tile 100.

[0084] like Figure 1 and Figure 4 As shown, in some embodiments, optionally, when the first joint 120 is provided with at least two drainage grooves 140 , the backlight side of the second joint 130 is also provided with a limiting portion 133 , and the limiting portion 133 is inserted into at least one drainage groove 140 of an adjacent photovoltaic tile 100 .
