However, the photovoltaic module has a disadvantage that pollutants can easily accumulate on the photovoltaic power generation panel (hereinafter referred to as a photovoltaic panel for convenience) due to meteorological phenomena such as yellow sand and bad weather.

When contaminants accumulate in the solar panel, the light absorption rate of the solar panel significantly decreases, and as a result, power generation efficiency decreases.
