Background

At present, the mainstream photovoltaic module takes a silicon-based battery piece as a core, and the highest photoelectric conversion efficiency is close to 20%. A large number of production practices show that photovoltaic modules placed in the open air tend to accumulate contaminants such as dust on the light-passing surfaces after being used for a period of time. The accumulation of dust obviously reduces the luminous flux of the photovoltaic module, and further obviously reduces the electric energy output capacity of the photovoltaic module. Quantitative analytical tests showed that dust accumulation of 4g/m reduced the efficiency of photovoltaic module power output by 60%. What is more, the accumulation of large dust or pollutants, such as leaves, bird droppings, etc., can generate a hot plate effect, resulting in local high temperature of the photovoltaic module until the photovoltaic module is burnt out and scrapped.

The existing solar photovoltaic panel cleaning modes mainly comprise manual cleaning, water washing cleaning and electrostatic cleaning. The manual cleaning mode is most energy-saving, power equipment is not needed, the cleanliness of manual cleaning is difficult to maintain, and the cleaning efficiency is low; the washing effect is good, but the water consumption is large, so that the resource waste is caused, and particularly, in some water-deficient areas, the water resource is more precious; the electrostatic cleaning saves time and labor, but the cleaning force generally cannot reach the required level.
