Magnetic dustproof photovoltaic panel

Abstract

The invention relates to a magnetic dustproof photovoltaic panel. The magnetic dustproof photovoltaic panel comprises a bracket and a power generation panel. The power generation panel is pie-shaped. A lower permanent magnet ring is embedded in a light receiving surface. The lower permanent magnet ring and the power generation panel are coaxially arranged. A dustproof shield is also flexibly installed above the power generation panel. The dustproof shield can freely rotate with the axis of the power generation panel acting as a rotating shaft. The cover plate of the dustproof shield is made of transparent material, and the blocking sides are made of ferromagnetic material. An upper permanent magnet ring is embedded in the cover plate. The positions of the upper permanent magnet ring and the lower permanent magnet ring exactly oppose and the same poles are repulsive. A wind fan is installed below the blocking sides, and permanent magnet sheets are equidistantly installed on the circular frame of the wind fan. According to the photovoltaic panel, pollution of dust to the photovoltaic panel can be effectively prevented, and damage of the hot spot effect to photoelectric elements can also be effectively prevented so that the service life of the photovoltaic panel can be greatly prolonged.

[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 failure, the cleanliness of photovoltaic panels is also particularly important; the surface pollution of photovoltaic modules has a significant impact on its power generation efficiency. The amount of radiation received by the surface; 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. Lifespan; 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, which wastes more resources and easily causes damage to the photovoltaic panels.
