Thirdly, an ice layer is formed on the surface of the panel when the solar panel is washed by water in winter, and the light energy capturing capability of the photovoltaic panel is influenced.
In conclusion, the existing cleaning modes of the photovoltaic cell panel have the defects and defects in different aspects and different degrees, so that the operation maintenance of the photovoltaic power station is greatly unchanged, and the operation efficiency of the photovoltaic power station is seriously influenced.
