Hot-spot-preventing photovoltaic panel

Abstract

The invention relates to a hot-spot-preventing photovoltaic panel. The hot-spot-preventing photovoltaic panel comprises a bracket and a power generation panel. Bracket is installed at the lower side of the power generation panel. The light receiving surface of the power generation panel is obliquely upward in the angle of 45 degrees. A rotating shaft is fixedly installed at the center of the power generation panel. A dust board sleeves the rotating shaft. The dust board is made of high-transmittance material and the profile of the dust board is pie-shaped. The circular side of the dust board is also provided with tooth slots. The hot-spot-preventing photovoltaic panel also comprises a wind fan. Teeth engaged with the tooth slots are equidistantly arranged at the edge of the wind fan. The wind fan is rotatably installed on the bracket. The edge of the wind fan is engaged with the circular side of the dust board. According to the photovoltaic panel, the hot spot effect can be effectively eliminated so that stable working of internal photoelectric elements can be guaranteed for a long time.

Description

technical field [0001] The invention relates to a photoelectric power generation material, in particular, a photovoltaic panel. Background technique [0002] With the deterioration of the environment and the deepening of human awareness of environmental protection, photovoltaic power generation, as one of the main green energy sources, has been applied more and more; photovoltaic power generation as solar power, the weather is the biggest factor restricting power generation, followed by human control In addition to avoiding losses caused by electrical equipment failures, the cleanliness of photovoltaic panels is also particularly important; the surface pollution of photovoltaic modules has a significant impact on the alignment of power generation efficiency. First, surface pollution affects the transmittance of light, which in turn affects the surface of modules The amount of radiation received; second, the adhesion of dirt to the surface of the solar panel will form a sha...

[0002] With the deterioration of the environment and the deepening of human awareness of environmental protection, photovoltaic power generation, as one of the main green energy sources, has been applied more and more; photovoltaic power generation as solar power, the weather is the biggest factor restricting power generation, followed by human control In addition to avoiding losses caused by electrical equipment failures, the cleanliness of photovoltaic panels is also particularly important; the surface pollution of photovoltaic modules has a significant impact on the alignment of power generation efficiency. First, surface pollution affects the transmittance of light, which in turn affects the surface of modules The amount of radiation received; second, the adhesion of dirt to the surface of the solar panel will form a shadow, which will generate a hot spot effect in the local area of ​​the photovoltaic module, thereby causing damage to the photovoltaic panel, affecting the power generation efficiency and shortening the life of the photovoltaic panel ;The traditional method is to regularly clean the dust on the photovoltaic panels. This method is complicated to operate and expensive. At the same time, the effect after cleaning is not very obvious. It wastes more resources and easily causes damage to the photovoltaic panels.
