The photovoltaic dust accumulation effect is one of the biggest problems encountered in the large-scale application of photovoltaic power generation. Large-scale photovoltaic power stations are mostly built in areas with long sunshine hours and little rain. If they are not cleaned for a long time, the power generation will drop by 20% to 30%, causing a lot of economic losses. Therefore, solving the dust accumulation problem has become a key task in the development of the photovoltaic industry. For this reason, photovoltaic cleaning robots came into being.
