Description

New photovoltaic tile

technical field

The utility model relates to a solar power generation system, in particular to a tile with photovoltaic power generation function.

Background technique

The roof photovoltaic power generation system (photovoltaic module) of the prior art uses profiles such as aluminum alloy as the frame and steel as the mounting bracket. There are single functions and styles, complex construction, large consumption of building materials, serious building pollution, and low utilization efficiency. They cannot directly replace traditional building materials to achieve true photoelectric building integration, and cannot meet the needs of individualized buildings. The high cost is not easy to promote and apply on a large scale. In order to improve the function of photovoltaic modules, someone has invented photovoltaic power generation tiles, such as Chinese patent CN1680673, a photovoltaic power generation tile, on the front of the tile base plate, a quick cable connection seat and a photovoltaic power generation component are fixed; There are waterproof grooves facing up and down. There is a fastening groove parallel to the waterproof groove on the back of the tile substrate and on the other edge of the waterproof groove opposite to the front. The width of the outer edge of the fastening groove is smaller than the width of the waterproof groove. The outer edge of the waterproof groove The width of the edge is smaller than the width of the fastening groove. Another example is the CN2788357 roof solar photovoltaic cell device, which includes a photovoltaic cell and a tile body. mouth.

Above-mentioned two patents can be arranged on the roof, but can't play the effect of directly replacing tile.

Contents of the invention

The main purpose of the utility model is: to solve the shortcomings of the existing technology, so as to develop a new type of photovoltaic tile that can be directly installed on the roof of the house without a bracket, has the function of replacing the "tile", is simple in construction, and has a high utilization rate.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions: a new type of photovoltaic tile, which is characterized in that it includes a substrate and a crystalline silicon solar cell that is located on the substrate and connected to the substrate by direct pressure bonding; The substrate is a ceramic tile. There is a layer of encapsulation layer made of transparent TPT (polyvinyl fluoride composite film) material on the photovoltaic power generation module. On the substrate between the crystalline silicon cell and the substrate, there are wire threading holes. There is a wire groove communicated with the wire threading hole. A fixing hole is opened on one side of the base plate. Used for tile-to-tile connections.

The crystalline silicon cell is directly die-cast on the ceramic tile to make it integrated, so as to completely solve the problems of connection strength and waterproof of the main body of the product.

The wires of the battery slices are passed through the wire holes to the back of the tiles, and the closed male and female interfaces are used to connect and the waterproof adhesive strips are used to protect the wires to ensure that the wires and interfaces will not cause short circuits due to rainwater entering.

The beneficial effects of the utility model are:

1. It makes up for the lack of a single style of photovoltaic application products on the market. There are various styles such as wavy, streamlined and "concave" for users to choose, which can meet the needs of different styles of buildings;

2. It has the functions of traditional building tiles and photovoltaic power generation, and truly realizes the integration of photovoltaic buildings.

3. It can be directly installed on the roof without conventional aluminum alloy frames and steel brackets. The construction is simple, the construction efficiency is high, and the construction materials and construction pollution can be greatly reduced.

4. The weight is light, which is 70% of the roof power generation system of the same scale, which effectively reduces the load of the building.

5. The performance of windproof, rainproof and hailproof has met the requirements of outdoor environment, and the service life is more than 25 years.

6. The price is low. Compared with the conventional roof power generation system, the total cost has dropped by more than 30%, and it can be popularized and applied in a large area.
