Description

Technical Field

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

[0002] Most of the existing photovoltaic tiles on sloped roofs are completed by adding frames around the photovoltaic modules, buckling them left and right, and overlapping them up and down. The main problems are as follows:

[0003] 1. The cost is relatively high. Taking the length of 1160mm, width of 390mm and power of 85Wp as an example, the cost of the surrounding frame is 0.35 yuan / W;

[0004] 2. Waterproofing is not good; the upper and lower joints are flat and require additional waterproof sealing strips;

[0005] 3. Poor heat dissipation: In order to prevent water leakage, the components are closely connected, and the ventilation and heat dissipation performance is poor, which reduces the power generation efficiency by more than 10%. Utility Model Content

[0006] The purpose of the utility model is to provide a photovoltaic tile for a slope roof, which is seamlessly overlapped by corrugated steel plates with a corrugated structure, thereby ensuring the reliability of installation, increasing the heat dissipation and drainage effects of the photovoltaic panel, and having high waterproof performance, thereby improving the power generation efficiency.

[0007] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0008] The utility model discloses a photovoltaic tile for a sloped roof, comprising:

[0009] A plate, comprising a plate body and a step portion connected to one side of the plate body; the plate body having first wave crests and first wave valleys alternately distributed at intervals; a top surface of the step portion having a second wave crest corresponding to the first wave crest, and a second wave valley corresponding to the first wave valley;

[0010] The photovoltaic panel is installed on the upper end surface of the panel.

[0011] A further solution includes overlapping portions arranged on two opposite sides of the plate, wherein the overlapping portions are inclined plates inclined downward.

[0012] A further solution: the lowest point of the inclined plate is on the extension line of the line connecting the lowest points of all the first wave valleys.

[0013] A further solution: the height difference between the first wave peak and the second wave peak is not less than the thickness setting of the photovoltaic panel.

[0014] A further solution: the first wave crest has a chamfered structure.

[0015] A further solution: the photovoltaic panel and the panel are bonded together by structural adhesive.

[0016] A further solution also includes a junction box disposed on the lower end surface of the photovoltaic panel, wherein the junction box is installed in the cavity between the first wave valley and the photovoltaic panel.

[0017] A further solution: the panel also includes a lower vertical edge strip arranged on the other side of the panel body.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] The panels used in the utility model have a corrugated structure, which is seamlessly overlapped by the step portion and the lower vertical edge strip, and seamlessly overlapped by the inclined plate on the left and right, forming a relatively complete whole on the slope roof, ensuring the reliability of installation, and ensuring waterproofness without gluing the overlapped joints, simplifying the installation steps. The panels have a corrugated structure, so that a large area of ​​ventilation and drainage channels are left between the panels and the photovoltaic panels, and gaps are left between the photovoltaic panels during installation, which greatly increases the heat dissipation and improves the power generation efficiency.

[0026] See also Figure 1-3 In this embodiment, a photovoltaic system installed on a sloping roof includes a panel and a photovoltaic panel 3 installed on the upper end surface of the panel, wherein:

[0027] The plate comprises a plate body 1 and a step portion 2 integrally connected to one side of the plate body 1; the plate body 1 has first wave crests 11 and first wave valleys 12 that are alternately distributed at intervals; the top surface of the step portion 2 has a second wave crest 21 corresponding to the first wave crest 11, and a second wave valley 22 corresponding to the first wave valley 12;

[0028] The photovoltaic panel 3 is installed on the upper end surface of the panel.

[0029] On the roof 7, the panels are arranged in an array, and the upper and lower rows of panels have a slope change as the roof 7 changes, the first wave crest 11 of the upper panel overlaps with the second wave crest 21 of the lower panel, and the first wave valley 12 of the upper panel overlaps with the second wave valley 22 of the lower panel to form an overall photovoltaic system.

[0030] Furthermore, it also includes overlapping parts 5 arranged on two opposite sides of the plate, and the overlapping parts 5 are inclined plates inclined downward. The first wave crests 11 and the first wave valleys 12 at the edge positions of adjacent plates in the same row are overlapped as a whole, and the inclined plates play a transition role.

[0031] Furthermore, the lowest point of the inclined plate is on the extension line of the line connecting the lowest points of all the first wave valleys 12. The inclined plate falls on the roof 7 to provide support.

[0032] Furthermore, the height difference between the first wave crest 11 and the second wave crest 21 is not less than the thickness setting of the photovoltaic panel 3. The step portion 2 not only plays a role of connecting the upper and lower parts, but also serves as a support and limiter for the side of the photovoltaic panel 3.

[0033] Furthermore, the first wave crest 11 has a chamfered structure. The chamfered structure can increase the contact area between the panel body 1 and the photovoltaic panel 3, and then be reinforced by structural adhesive to improve the firmness of the connection.

[0034] Furthermore, it also includes a junction box 6 disposed on the lower end surface of the photovoltaic panel 3. The wave-shaped design of the panel body 1 is not only conducive to drainage and heat dissipation, but also provides a storage space for the accessories of the photovoltaic panel 3 (junction box 6).

[0035] Furthermore, the panel also includes a lower vertical edge strip 13 arranged on the other side of the panel body 1, which also has a corrugated structure. The lower vertical edge strip 13 has the same outer contour as the step portion 2. The lower vertical edge strip 13 of the upper row of panels is overlapped on the step portion 2 of the lower row of panels, so that the upper and lower rows of panels are overlapped to form a relatively complete whole, which can better divert rainwater.

[0036] Furthermore, the photovoltaic panel 3 is a frameless double-glass component, and the panel is a corrugated steel plate. The corrugated steel plate and the frameless double-glass component are shipped after being assembled in the factory.

[0037] When installing the utility model, the tiles are laid row by row from the lower left corner of one side of the sloping roof to the ridge. First, the tile hanging strip 4 is installed; then the two panels are laid from left to right in sequence, the cables of the two panels are checked and connected, and after the test is passed, the step portion 2 is fixed to the tile hanging strip 4 with self-tapping screws, and then the next photovoltaic tile is installed, and the above steps are repeated until a row is completed; when installing the upper row of photovoltaic tiles, the upper row of lower vertical side strips 13 are fixed to the lower row of step portions 2 by self-tapping screws.

This description 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 may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.

[0039] 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 changes made according to the scope of the claims of the present application are within the protection scope of the claims of the present application.
