Method for eliminating hot spot effect of magneto-motive dust-proof photovoltaic panel

Abstract

The present invention relates to a method for eliminating the hot spot effect of a magneto-motive dustproof photovoltaic panel. The magneto-motive dustproof photovoltaic panel comprises a support and a power generating panel; the power generating panel is in the shape of a round cake; a lower permanent magnetic ring is embedded in the light receiving surface of the power generating panel; the lower permanent magnetic ring is coaxial with the power generating panel; a dustproof cover is movably mounted above the power generating panel; the dustproof cover can rotate freely with the axis of the power generating panel adopted as a rotation axis; the cover plate of the dustproof cover is made of a transparent material; the flange of the dustproof cover is made of a ferromagnetic material; an upper permanent magnet ring is embedded in the cover plate; the upper permanent magnet ring is aligned with the lower permanent magnet ring; the poles of the upper permanent magnet ring and the lower permanent magnet ring, which have the polarity, repulse each other; wind power fans are mounted below the flange; and the circular frames of the wind power fans are equidistantly provided with permanent magnet sheets. The photovoltaic panel can effectively prevent from being polluted by dust, and the hot spot effect can be effectively prevented from damaging a photovoltaic component, and therefore, the service life of the photovoltaic panel can be greatly prolonged.

[0003] 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.
