Photovoltaic tiles encapsulate photovoltaic module units into tiles through gluing and pressing, giving building materials the properties of photovoltaic power generation. Photovoltaic panels absorb solar energy and convert it into electrical energy stored in batteries for use in small-power household appliances, which can reduce the power load; at the same time, solar power generation is a green, environmentally friendly, sustainable and renewable energy. With the shortage of energy, solar power generation technology has received more and more attention.

[0003] The existing public technical solution, with announcement number CN220203203U, discloses a photovoltaic tile, in which the overall structure of the photovoltaic tile is set to an arch structure. The entire arch structure is composed of a number of ridge units. While increasing the lighting area, each ridge unit is successively raised compared to the horizontal plane and does not block each other, thereby avoiding the side facing away from the sun from becoming a shadow side; the cross-section of the ridge unit is set to an isosceles triangle, thereby avoiding the situation in which the peaks of the wave-type panels generally block the troughs and cause the yin and yang sides, thereby reducing the lighting area.

[0004] When the above technical solutions are actually implemented, traditional photovoltaic modules are usually installed in power stations and factories. These locations are generally located in remote areas and usually do not need to consider light pollution issues.

[0030] Preferably, a first connecting layer 12 is arranged below the anti-glare glass layer 11, and a battery layer 13 is arranged below the first connecting layer 12, a second connecting layer 14 is arranged below the battery layer 13, and a back panel 15 is arranged below the second connecting layer 14, the anti-glare glass layer 11, the first connecting layer 12, the second connecting layer 14 and the back panel 15 have the same size, and the anti-glare glass layer 11, the first connecting layer 12, the second connecting layer 14 and the back panel 15 are larger than the size of the battery layer 13, the anti-glare glass layer 11 is bonded to the battery layer 13 through the first connecting layer 12, and the battery layer 13 is bonded to the back panel 15 through the second connecting layer 14, and a sealant is arranged between the photovoltaic tile body 1 and the lightweight aluminum alloy frame 2.

[0031] By adopting the above technical solution, the photovoltaic tile body 1 is formed into an integrated whole by stacking the anti-glare glass layer 11, the first connecting layer 12, the battery layer 13, the second connecting layer 14 and the back plate 15 in sequence from top to bottom.

[0032] The anti-glare glass layer 11 is provided by a PET layer (112) and a PVF layer 113, and is coated with a nano coating 111 to improve the reliability of the photovoltaic tile. The surface of the anti-glare glass layer 11 is frosted to effectively reduce glare. The cell layer 13 includes a plurality of solar cell strings, and the format can be adjusted according to demand. The cell can be a bifacial crystalline silicon solar cell, a Topcon cell, a thin film cell, or a PERC cell, and is interconnected by a welding ribbon. The first connecting layer 12 contains EVA and POE that reduce melt viscosity and increase fluidity. The melt viscosity and fluidity increase additives include but are not limited to viscosity regulators. The second connecting layer 14 includes any one of EVA, POE, PVB, and EPE.

[0033] Specifically, Figure 2 and Figure 3 As shown, the drainage assembly 4 includes a splicing rod 42, a drainage groove 43 is opened on the top of the splicing rod 42, and limit baffles 41 are arranged on the left and right sides of the drainage groove 43, a reinforcement hole 44 is opened inside the splicing rod 42, and a reinforcement rope 45 is passed through the reinforcement hole 44, the connecting groove 3 is adapted to the size of the splicing rod 42, and the limit baffle 41 and the connecting groove 3 are abutted against each other, and the drainage groove 43 and the limit baffle 41 form a U-shaped structure.

[0034] By adopting the above technical solution, when two groups of photovoltaic tile bodies 1 are connected, the splicing rod 42 is inserted into the connecting groove 3.

After lamination, the overflowing glue is trimmed to prepare for the installation of the frame. The frame used for the photovoltaic tile is a lightweight aluminum alloy frame 2, and different colors can be used as required; sealant is injected into the overflowing glue groove inside the lightweight aluminum alloy frame 2, and then assembled around the component.

The sealant connecting the junction box and the component also needs to overflow to achieve the purpose of blocking water vapor penetration. Then the photovoltaic tile body 1 can be installed and spliced ​​as needed.
