Description

Technical Field

[0001] This application relates to the field of photovoltaic power generation technology, and in particular to photovoltaic tiles and photovoltaic power generation devices. Background Technology

[0002] With the development of photovoltaic technology, photovoltaic tiles have emerged. These are integrated products that combine solar power generation technology with traditional building tiles, representing an important branch of building-integrated photovoltaics (BIPV). When using photovoltaic tiles, adjacent tiles are interconnected. Their core objective is to replace traditional roofing materials while simultaneously fulfilling building functions and generating clean energy.

[0003] In related technologies, photovoltaic tiles have a frame and a front glass. The frame surrounds the edge of the photovoltaic tile and is used to fix the photovoltaic tile to the main keel. However, the frame will cover the surface of the front glass, thus occupying effective installation space. This prevents the solar cells from covering the edge of the photovoltaic tile, restricts the close arrangement of the solar cells, and thus reduces the photoelectric conversion efficiency of the photovoltaic tile. Utility Model Content

[0004] Therefore, it is necessary to provide a photovoltaic tile and a photovoltaic power generation device to address the problem of low photoelectric conversion efficiency in related technologies.

[0005] A photovoltaic tile, comprising:

[0006] The front glass has a first connecting portion at one end along a first direction;

[0007] The rear glass is located on one side of the front glass in the first direction, and the other end of the rear glass along the first direction has a second connecting portion;

[0008] Along the first direction, a first connecting part is provided at one end protruding from the rear glass, and a second connecting part is provided at the other end protruding from the front glass. The first connecting part is used to be attached to the second connecting part of the adjacent rear glass.

[0009] The first frame is fixed between the first connecting part and the back glass. The projection of the first frame along the second direction is located on the first connecting part and the back glass. The second direction is set perpendicular to the first direction.

[0010] The second frame is fixed to the side of the second connector that faces away from the front glass.

[0011] In one embodiment, the front glass has a third connecting portion on one side along the third direction, and the back glass has a fourth connecting portion on the other side along the third direction, wherein the third direction, the first direction, and the second direction are perpendicular to each other.

[0012] Along the third direction, the third connecting part is provided at one end protruding from the rear glass, and the fourth connecting part is provided at the other end protruding from the front glass. The third connecting part is used to be mounted on the fourth connecting part of the adjacent rear glass.

[0013] Photovoltaic tiles also include:

[0014] The third frame is fixed between the third connecting part and the back glass, and the projection of the third frame along the second direction is located on the third connecting part and the back glass.

[0015] The fourth frame is fixed to the side of the back glass that is away from the front glass.

[0016] In one embodiment, the third frame includes a first limiting portion, and the fourth frame includes a second limiting portion. The first limiting portion abuts against the adjacent second limiting portion to limit the position of the third frame and the adjacent fourth frame.

[0017] In one embodiment, the first limiting part includes a first limiting rod disposed along a third direction, and the second limiting part includes a second limiting rod disposed along a third direction, and the first limiting rod abuts against the adjacent second limiting rod.

[0018] In one embodiment, a connecting rod is provided on the second limiting rod, and the connecting rod extends along a second direction.

[0019] In one embodiment, the first frame is glued to the first connecting portion, and / or the first frame is glued to the back glass; the second frame is glued to the second connecting portion.

[0020] A photovoltaic power generation device includes a plurality of photovoltaic tiles provided above, which are arranged in an array along a first direction and a third direction.

[0021] In one embodiment, the first frame includes a first through portion, the second frame includes a second through portion, and the photovoltaic power generation device further includes;

[0022] The first support beam is arranged along a third direction and passes through the first penetration part of multiple photovoltaic tiles distributed along the third direction;

[0023] The second support beam is set along the third direction and passes through the second penetration section of multiple photovoltaic tiles distributed along the third direction.

[0024] In one embodiment, the first frame, the first connecting portion, and the adjacent second connecting portion are bonded and fixed together.

[0025] In one embodiment, the first frame includes a first fixing groove and a first opening, wherein the cross-sectional area of ​​the first opening along the second direction is smaller than the cross-sectional area of ​​the first fixing groove along the second direction.

[0026] The photovoltaic power generation device also includes a sealing strip. The first frame, the first connecting part and the adjacent second connecting part are bonded and fixed together by the sealing strip, and part of the sealing strip is located in the first fixing groove.

[0027] In the aforementioned photovoltaic tile, the front and back glass are staggered in the first direction. The projection of the first frame in the second direction falls entirely within the area of ​​the first connecting portion and the back glass, allowing the first frame to be shielded by the front glass. Simultaneously, the first connecting portion overlaps with the second connecting portion of the back glass of the adjacent photovoltaic tile, effectively covering the second frame of the adjacent photovoltaic tile. Therefore, when viewed from the second direction, the front glass completely shields the first frame, and the first connecting portion also covers the adjacent second frame. Thus, with this structure, the solar cells can cover both ends of the photovoltaic tile along the first direction, increasing the area where the cells can be arranged and allowing for a tighter arrangement of the cells in the first direction, thereby improving the photovoltaic conversion efficiency of the photovoltaic tile.

[0047] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0051] See Figure 1This application provides a photovoltaic tile, which includes a front glass 110, a back glass 120, a first frame 130, and a second frame 140. The front glass 110 has a first connecting portion 111 at one end along a first direction. The back glass 120 is located on one side of the front glass 110 along the first direction, and has a second connecting portion 121 at the other end along the first direction. Along the first direction, the first connecting portion 111 protrudes from one end of the back glass 120, and the second connecting portion 121 protrudes from the other end of the front glass 110. The first connecting portion 111 is used to rest on the second connecting portion 121 of the adjacent back glass 120. The first frame 130 is fixed between the first connecting portion 111 and the back glass 120. The projection of the first frame 130 along a second direction is located on the first connecting portion 111 and the back glass 120, and the second direction is perpendicular to the first direction. The second frame 140 is fixed to the side of the second connecting portion 121 facing away from the front glass 110. (See reference...) Figure 1 The X direction is the first direction, and the Z direction is the second direction, which is the direction of illumination. The solar cell is located between the front glass 110 and the back glass 120.

[0052] Applying the technical solution of this application, the front glass 110 and the back glass 120 are staggered in the first direction, and the projection of the first frame 130 in the second direction completely falls within the area of ​​the first connecting portion 111 and the back glass 120, so that the first frame 130 can be shielded by the front glass 110. Simultaneously, the first connecting portion 111 overlaps with the second connecting portion 121 of the back glass 120 of the adjacent photovoltaic tile, thereby effectively covering the second frame 140 of the adjacent photovoltaic tile. Therefore, when viewed in the second direction, the front glass 110 can completely shield the first frame 130, and the first connecting portion 111 can also cover the adjacent second frame 140. Therefore, with the above structure, the solar cells can cover both ends of the photovoltaic tile along the first direction, increasing the area where the solar cells can be arranged, allowing the solar cells to be densely arranged in the first direction, and improving the photovoltaic conversion efficiency of the photovoltaic tile.

[0053] In some embodiments, the first border 130 and the second border 140 are disposed on the main body keel.

[0054] In some embodiments, the thickness of both the front glass 110 and the back glass 120 is 3.2 mm.

[0055] In some embodiments, due to errors caused by the construction process, there is typically a seam of about 7 mm between the front glass 110 and the back glass 120 of the adjacent photovoltaic tile.

[0056] In some embodiments, the first direction can be the length direction of the photovoltaic tile or the width direction of the photovoltaic tile.

[0057] See Figure 2 The Y direction is the third direction.

[0058] See Figure 2 The front glass 110 has a third connecting portion 112 on one side along a third direction, and the back glass 120 has a fourth connecting portion 122 on the other side along a third direction. The third direction, the first direction, and the second direction are mutually perpendicular. Along the third direction, the third connecting portion 112 protrudes from one end of the back glass 120, and the fourth connecting portion 122 protrudes from the other end of the front glass 110. The third connecting portion 112 is used to mount on the fourth connecting portion 122 of the adjacent back glass 120. The photovoltaic tile also includes a third frame 150 and a fourth frame 160. The third frame 150 is fixed between the third connecting portion 112 and the back glass 120, and the projection of the third frame 150 along the second direction is located on the third connecting portion 112 and the back glass 120. The fourth frame 160 is fixed on the side of the back glass 120 opposite to the front glass 110. With this configuration, the front glass 110 and the back glass 120 are offset in the third direction. The projection of the third frame 150 in the second direction falls entirely within the area of ​​the third connecting portion 112 and the back glass 120, allowing the third frame 150 to be shielded by the front glass 110. Simultaneously, the third connecting portion 112 overlaps with the fourth connecting portion 122 of the back glass 120 of the adjacent photovoltaic tile, effectively covering the fourth frame 160 of the adjacent photovoltaic tile. Viewed from the second direction, the front glass 110 completely shields the third frame 150, and the third connecting portion 112 also shields the adjacent fourth frame 160. Since the third direction is perpendicular to the first direction, no frame is visible from the second direction. Using this structure, the solar cells can cover both ends of the photovoltaic tile along the third direction, allowing the solar cells to cover the entire edge of the photovoltaic tile, further increasing the area where the solar cells can be arranged, and thus further improving the photovoltaic conversion efficiency of the photovoltaic tile.

[0059] In this technology, the width of the frame on the front glass 110 is generally between 1cm and 3cm. The photovoltaic tiles of this technology generate about 50% less electricity per square meter than traditional photovoltaic modules. To achieve the same amount of electricity, more installation space is required. However, by adopting the technical solution of this application, the power generation of the photovoltaic tiles is almost the same as that of traditional photovoltaic modules.

[0060] In related technologies, photovoltaic tiles are mostly used in rooftop BIPV (Building Integrated Photovoltaics). BIPV requires photovoltaic modules to be deeply integrated with the building's appearance. However, when installed on rooftops, the edges of adjacent photovoltaic tiles can form raised gaps, resulting in a checkerboard-like surface that fails to create a smooth and continuous visual effect. This uneven surface is particularly jarring in modern buildings such as glass curtain walls and metal roofs, contradicting the minimalist aesthetic requirements of architectural design and disrupting the overall flatness and smoothness of the building surface. However, in this application, because the edges are not visible from a second-direction view, only the front glass 110 and part of the back glass 120 are exposed, allowing multiple photovoltaic tile surfaces to form a smooth and unified whole, improving surface flatness and continuity.

[0061] In related technologies, traditional frame materials such as aluminum alloys have high light reflectivity, causing some light to be unable to reach the surface of the solar cells due to frame reflection. Furthermore, dark-colored frame materials such as black plastic absorb some light energy, converting it into heat instead of electricity. Both of these situations reduce light energy utilization, further affecting power generation efficiency. However, in this application, a hidden frame is used, which does not reflect or absorb light energy, and avoids shadows cast by the frame when the angle of illumination changes. This significantly improves power generation stability, especially under conditions of early morning / evening or oblique sunlight.

[0062] In this application, the first direction is the length direction of the photovoltaic tile, the third direction is the width direction of the photovoltaic tile, and the photovoltaic tiles are staggered along the third direction to adapt to diverse architectural appearance requirements, achieving overall aesthetics and unity with the building.

[0063] See Figure 2 The third frame 150 includes a first limiting part, and the fourth frame 160 includes a second limiting part. The first limiting part abuts against the adjacent second limiting part to restrict the position of the third frame 150 and the adjacent fourth frame 160. This arrangement, by providing the mutually abutting first and second limiting parts, provides positioning and limiting for the connection of adjacent photovoltaic tiles in the third direction. This improves the convenience of the installation process, allowing workers to receive feedback when pushing the photovoltaic tiles to the predetermined position, ensuring accurate installation, reducing installation errors, improving construction quality and efficiency, and simultaneously reducing the operational difficulty for workers.

[0064] Specifically, the first limiting part includes a first limiting rod 151, which is arranged along a third direction. The second limiting part includes a second limiting rod 161, which is also arranged along a third direction. The first limiting rod 151 abuts against the adjacent second limiting rod 161. In this application, the first limiting rod 151 and the second limiting rod 161 are arranged along a first direction. This arrangement facilitates the processing of the third frame 150 and the fourth frame 160, resulting in a simple structure. Furthermore, while fulfilling their limiting function, the first limiting rod 151 and the second limiting rod 161 occupy very little space, which contributes to the compactness of the overall photovoltaic tile structure and avoids affecting the power generation area and aesthetics of the photovoltaic tile.

[0065] Furthermore, a connecting rod 162 is provided on the second limiting rod 161, extending along the second direction. This arrangement allows the connecting rod 162 to abut against the first limiting rod 151 when the third frame 150 and the fourth frame 160 are misaligned in the second direction, thus further improving the accuracy of photovoltaic tile assembly.

[0066] In some embodiments, a reinforcing rod may be provided between the second limiting rod 161 and the connecting rod 162 to enhance the structural strength and bending resistance of the fourth frame 160 and reduce the possibility that the second limiting rod 161 will tilt when it abuts against the first limiting rod 151.

[0067] See Figure 1 The first frame 130 is glued to the first connecting part 111, and / or the first frame 130 is glued to the back glass 120, and the second frame 140 is glued to the second connecting part 121. In this application, the first frame 130 is glued to the first connecting part 111, and the first frame 130 is glued to the back glass 120. This arrangement facilitates the connection between the first frame 130 and the first connecting part 111, the first frame 130 and the back glass 120, and the second frame 140 and the second connecting part 121. At the same time, the glued fixation achieves uniform stress distribution, avoids drilling holes in the front glass 110 or the back glass 120, eliminates the risk of cracks caused by drilling, and avoids stress concentration on the front glass 110 or the back glass 120, thereby improving the reliability of the photovoltaic tile.

[0068] See Figure 2The third frame 150 is glued to the third connecting part 112, and / or the third frame 150 is glued to the back glass 120; the fourth frame 160 is glued to the back glass 120. In this application, the third frame 150 is glued to the third connecting part 112, and the third frame 150 is glued to the back glass 120. This arrangement facilitates the connection between the third frame 150 and the third connecting part 112, the third frame 150 and the back glass 120, and the fourth frame 160 and the back glass 120. Simultaneously, the glued fixation achieves uniform stress distribution, avoids drilling holes in the front glass 110 or the back glass 120, eliminates the risk of cracking caused by drilling, and prevents stress concentration on the front glass 110 or the back glass 120, thus improving the reliability of the photovoltaic tile.

[0069] In this application, the first frame 130 is bonded and fixed to the first connecting part 111 and the back glass 120, the second frame 140 is bonded to the second connecting part 121, the third frame 150 is bonded to the third connecting part 112 and the back glass 120, and the fourth frame 160 is bonded to the back glass 120 using structural adhesive 170. Simultaneously, the structural adhesive 170 has a good sealing effect, effectively preventing the intrusion of moisture, dust, and other impurities, ensuring the normal operation of the battery cells.

[0070] See Figure 3 Another embodiment of this application provides a photovoltaic power generation device, which includes a plurality of photovoltaic tiles 100 provided above, and the plurality of photovoltaic tiles 100 are arranged in an array along a first direction and a third direction. The photovoltaic power generation device using the photovoltaic tiles 100 provided in this application has a significantly improved photoelectric conversion efficiency, and the photovoltaic power generation device has a smooth and continuous visual effect.

[0071] In some embodiments, photovoltaic power generation devices may be installed on rooftops.

[0072] See Figure 4 The first frame 130 includes a first through-hole portion 131, and the second frame 140 includes a second through-hole portion 141. The photovoltaic power generation device also includes a first support beam 300 and a second support beam 400. The first support beam 300 is arranged along a third direction and passes through the first through-hole portions 131 of a plurality of photovoltaic tiles 100 distributed along the third direction. The second support beam 400 is arranged along a third direction and passes through the second through-hole portions 141 of a plurality of photovoltaic tiles 100 distributed along the third direction. This arrangement provides a supporting foundation for the photovoltaic tile 100 array, and the first through-hole portions 131 and second through-hole portions 141 facilitate the fixing of the photovoltaic tiles 100 to the first support beam 300 and second support beam 400, reducing on-site installation difficulty.

[0073] See Figure 5 The third frame 150 includes a third through-hole 153, and the fourth frame 160 includes a fourth through-hole 163. The photovoltaic power generation device also includes a third support beam 500 and a fourth support beam 600. The third support beam 500 is arranged along a first direction and passes through the third through-hole 153 of a plurality of photovoltaic tiles 100 distributed along the first direction. The fourth support beam 600 is arranged along the first direction and passes through the fourth through-hole 163 of a plurality of photovoltaic tiles 100 distributed along the first direction. This arrangement provides a supporting foundation for the photovoltaic tile 100 array with the third support beam 500 and the fourth support beam 600, while the third through-hole 153 and the fourth through-hole 163 facilitate fixing the photovoltaic tiles 100 to the third support beam 500 and the fourth support beam 600, reducing the difficulty of on-site installation.

[0074] In this application, the first through-hole 131, the second through-hole 141, the third through-hole 153 and the fourth through-hole 163 are all provided with through-holes.

[0075] The first frame 130, the first connecting part 111, and the adjacent second connecting part 121 are bonded and fixed together. This arrangement reduces the difficulty of connecting the first frame 130, the first connecting part 111, and the adjacent second connecting part 121, improves stress distribution, and increases the service life of the photovoltaic tile 100.

[0076] Furthermore, the third frame 150, the third connecting part 112, and the adjacent fourth connecting part 122 are bonded and fixed together. This arrangement reduces the difficulty of connecting the third frame 150, the third connecting part 112, and the adjacent fourth connecting part 122, improves stress distribution, and increases the service life of the photovoltaic tile 100.

[0077] Specifically, the first frame 130 includes a first fixing groove 1321 and a first opening 1322. The cross-sectional area of ​​the first opening 1322 along the second direction is smaller than the cross-sectional area of ​​the first fixing groove 1321 along the second direction. The photovoltaic power generation device also includes a sealing strip 200. The first frame 130, the first connecting part 111, and the adjacent second connecting part 121 are bonded and fixed together by the sealing strip 200, with a portion of the sealing strip 200 located within the first fixing groove 1321. This arrangement prevents the sealing strip 200 from falling out of the first fixing groove 1321, ensuring the stability of the connection between the sealing strip 200 and the first frame 130.

[0078] The third frame 150 includes a third fixing groove 1521 and a third opening 1522. The cross-sectional area of ​​the third opening 1522 along the second direction is smaller than the cross-sectional area of ​​the third fixing groove 1521 along the second direction. The third frame 150, the third connecting part 112, and the adjacent fourth connecting part 122 are bonded and fixed together by a sealing strip 200, with part of the sealing strip 200 located within the third fixing groove 1521. This arrangement prevents the sealing strip 200 from falling out of the third fixing groove 1521, ensuring the stability of the connection between the sealing strip 200 and the third frame 150.

[0079] Furthermore, in this application, the first frame 130 includes a first fixing part 132, on which a first fixing groove 1321 and a first opening 1322 are provided, and structural adhesive 170 is disposed between the first fixing part 132, the back glass 120, and the first connecting part 111. The second frame 140 has a second fixing part 142, on which a groove 1421 is provided, and structural adhesive 170 is disposed between the groove 1421 and the back glass 120. The third frame 150 includes a third fixing part 152, on which a third fixing groove 1521 and a third opening 1522 are provided, and structural adhesive 170 is disposed between the third fixing part 152, the back glass 120, and the third connecting part 112.

[0080] In some embodiments, the first border 130 and the third border 150 have the same structure.

[0081] In related technologies, adjacent photovoltaic tiles 100 are typically connected by multiple bolts. If a photovoltaic tile 100 has a quality problem, disassembly and replacement are more difficult and maintenance costs are higher compared to traditional photovoltaic modules. However, in this application, the sealing strip 200 facilitates the installation between adjacent photovoltaic tiles 100, significantly improving installation efficiency. Furthermore, it makes it easier to disassemble the photovoltaic tile 100 when a quality problem occurs.

[0082] 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.

[0083] 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.
