Technical field

Background technique

With the development of photovoltaic technology, there are more and more application scenarios and increasingly rich products, from the initial aerospace to ground power stations, lawn lights, wall photovoltaics or industrial and commercial roofs, etc. Among them, the combination of photovoltaics and roofs has received widespread attention, and many companies have developed similar curved photovoltaic tiles.

Curved photovoltaic tiles are close to traditional Chinese tiles in shape and appearance. The roof can directly replace the characteristics of traditional tiles without too much modification, so that it has the inherent performance of tiles and can also provide electrical energy output. For example, CN106906958A discloses a photovoltaic building flexible curved tile component and its production process. The photovoltaic building flexible curved tile component includes a first curved surface wavy transparent glass, a first curved surface wavy flexible sandwich material, a first curved surface wavy transparent glass, and a flexible thin film solar energy The chip, the second curved surface corrugated flexible laminate material and the curved surface corrugated flexible back plate; the first curved surface corrugated transparent glass and the curved surface corrugated flexible back plate are paired and fired. However, curved photovoltaic tiles have low power generation due to their curved shape. In addition, curved shape materials and special processes are required to make them, which results in high cost, resulting in low overall cost performance.

Compared with curved photovoltaic tiles, flat photovoltaic tiles not only have higher power generation, but also have lower costs. For example, CN214195245U discloses a solar flat tile and its connection structure, including a front panel, a solar cell, a first side support frame, and a second side support. Frame and hook, the front panel is made of transparent material, the solar cell is fixed on the underside of the front panel, the first side support frame is fixed on one side of the front panel and the solar cell, the second side support frame is fixed on the other side of the front panel and the solar cell. On one side, the hook is fixed to the underside of the solar cell. CN214531580U discloses a solar flat tile installation structure, which includes a keel and solar tiles arranged on the top surface of a building. Several solar tiles are spliced on the upper side of the keel and covered on the upper side of the building top surface. Each solar tile The tops of the tiles extend between the upper side and the adjacent solar tiles and keels. Each adjacent solar tile is spliced through a plug-in device, and the adjacent solar tiles are sealed and connected. The lower sides of the tiles are provided with connecting parts for connecting to the keels. However, the above-mentioned device has a complex structure and high cost, and the power generation efficiency needs to be further improved.

Therefore, providing a new type of solar flat tile with high power generation efficiency, low cost and suitable for market application is an urgent technical problem to be solved.
