Description

Technical Field

[0001] The utility model relates to the field of photovoltaics, in particular to a photovoltaic tile and a photovoltaic sloping roof. Background Art

[0002] Photovoltaic tiles integrate photovoltaic modules into tiles, giving them both the basic properties of tiles, such as waterproofing and heat insulation, and the ability to generate electricity. Existing photovoltaic tiles for sloped roofs are mostly installed using a frame, with a frame around the photovoltaic module, which snaps together left and right, and overlaps top and bottom to form a complete unit.

[0003] Existing photovoltaic tiles have the following problems:

[0004] 1. High material costs. Taking a PV module with a length of 1170mm, a width of 390mm, and a power of 90Wp as an example, the cost of the surrounding frame is 0.35 yuan / W;

[0005] 2. Module replacement is inconvenient. The frame is fixed to the tile hanging strips with self-tapping screws and is covered by the upper tiles. The modules are embedded in the frame. If you want to replace a photovoltaic module, you need to remove it one by one in order. Utility Model Content

[0006] The purpose of the utility model is to provide a photovoltaic tile and a photovoltaic slope roof, in which the lining plate and the photovoltaic panel are fixed together by bonding, the left and right sides of the photovoltaic tile are also connected by bonding, and the upper and lower sides are installed on the tile hanging strips by overlapping and snapping.

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] In the description of the present invention, it should be noted that the terms "upper", "lower", "left", "right", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are the directions or positional relationships in which the product of the present invention is usually placed when in use. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as a limitation on the present invention.

[0029] See also Figures 1 to 4 In this embodiment, a photovoltaic tile includes a photovoltaic panel 1 and a backing plate 2 bonded to the bottom of the photovoltaic panel 1. The backing plate 2 has a covering area 21 at one end and an overlapping area 22 at the other end. The photovoltaic panel 1 is mounted on the covering area 21, and the overlapping area 22 is provided with an adhesive layer 23 for overlapping adjacent backing plates 2. One side of the backing plate 2 is bent downward to form a vertical edge 24, and the other side is bent upward to form a snap-fit portion 25. The photovoltaic panel 1 and the backing plate 2 are tightly bonded together using a neutral silicone structural sealant. Neutral silicone structural sealant is specifically designed for bonding photovoltaic modules. It has excellent weather resistance and sealing properties, and a normal service life of not less than 30 years.

[0030] It should be noted that, in the present embodiment, one photovoltaic panel 1 is bonded to each backing board 2 . In other embodiments, 2 to 3 photovoltaic panels 1 may be bonded side by side to one backing board 2 according to the actual size of the photovoltaic panel 1 .

[0031] Furthermore, the adhesive layer 23 is a waterproof tape, such as a closed-cell polyethylene foam tape. Closed-cell polyethylene foam waterproof tape is a conventional tape product, primarily composed of a closed-cell polyethylene foam substrate coated with a waterproof adhesive. This waterproof tape offers excellent waterproofness and weather resistance, providing a secure and waterproofing effect when two adjacent liner panels 2 are overlapped and staggered.

[0032] Furthermore, the buckling portion 25 is connected to the edge strip 3 via a fastener, such as a fastening screw.

[0033] Furthermore, the photovoltaic panel 1 is a frameless double-glass component, which is lighter and has a lower cost than a framed photovoltaic component.

[0034] Furthermore, a lower hem 26 is provided at one end of the liner 2 near the overlap region 22. Since the liner 2 itself has a certain thickness, when adjacent liner 2 are overlapped with one side offset, one end of the liner is prone to downward disturbance, that is, downward displacement or deformation at the overlap. The lower hem 26 provides support for the liner 2 and balances the forces at both ends of the liner 2.

[0035] Furthermore, the lining plate 1 is made of metal, such as steel.

[0036] Furthermore, the junction box of the photovoltaic panel 1 is installed at the bottom of the lining board 2 .

[0037] Please continue reading Figure 5 This embodiment also discloses a photovoltaic slope roof, comprising a plurality of hemming strips 3 laid transversely and spaced apart from each other in the direction from the ridge to the eaves, lining boards 2 overlapped in rows on adjacent hemming strips 3, and photovoltaic panels 1 installed on the lining boards 2; wherein the lining boards 2 adopt the above-mentioned lining boards 2; the photovoltaic panels 1 adopt the above-mentioned photovoltaic panels, and the buckling portion 25 of the photovoltaic panel has an outer contour that matches the hemming strips 3. The spacing of the hemming strips 3 is pre-designed according to the roof conditions, and the lining boards 2 can adapt to the installation of photovoltaic panels 1 with varying sizes within a certain range, and have strong versatility. The photovoltaic panels 1 can be installed in a staggered manner or aligned ( Figure 5 The upper part is aligned for installation, while the lower part is staggered for installation). Aligned installation makes the entire roof structure more orderly and flat, while staggered installation can leave installation space for the vents on the roof. You can flexibly choose according to the actual working conditions.

[0038] Before the installation of the present invention, the lining board 2 and the photovoltaic panel 1 are bonded before leaving the factory, and double-sided tape is pre-pasted in the overlap area 22; during installation, the hanging edge strips 3 are installed according to the preset size, the backing paper of the double-sided tape is peeled off, and the photovoltaic tiles composed of the lining board 2 and the photovoltaic panel 1 are overlapped in a row along the length direction of the hanging edge strips 3, so that the buckling part and the vertical edge part are overlapped on the adjacent hanging edge strips 3 respectively, and all the photovoltaic tiles face the same direction. After installing one row, the next row is installed until all the photovoltaic tiles are installed. It should be pointed out in particular that the upper and lower overlaps of the photovoltaic tiles are overlapped together in the order of the hanging tile strips 3, the buckling part 25, and the vertical edge part 24 from low to high, and fixed by fasteners.

[0039] When a photovoltaic panel 1 needs to be replaced, a hot melt knife is inserted into the gap between the photovoltaic panel 1 and the backing plate 2 to melt the adhesive, and then the photovoltaic panel is removed. Finally, the remaining adhesive strips are cleaned with a hot melt knife, and a new adhesive layer and double-sided tape are applied, and the new photovoltaic panel 1 is bonded.

[0040] Although this specification is described according to implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.

[0041] Therefore, the above description is only a preferred embodiment of the present application and is not intended to limit the scope of implementation of the present application; that is, all equivalent modifications made according to the scope of the claims of the present application are within the scope of protection of the claims of the present application.
