With the improvement of people's understanding of renewable energy and the improvement of solar photovoltaic power generation systems, performance and price ratio, the development and application prospects of solar energy resources are becoming more and more broad. When the solar panels of photovoltaic power stations are used for a long time, dust, bird droppings, leaves and other impurities will adhere to the surface, which will block part of the sunlight and affect the efficiency of photovoltaic power generation. Regular cleaning and maintenance are required.

[0003] In the prior art, when cleaning the surface of the solar panels of a photovoltaic power station, a relatively large photovoltaic power station can use a photovoltaic cleaning robot or a dedicated photovoltaic cleaning machine to clean the solar panels, but the cost of the photovoltaic cleaning robot or photovoltaic cleaning machine is relatively high and is not suitable for household photovoltaic power stations. For household photovoltaic power stations, the owner may use a high-pressure water gun, a soft brush, a cotton mop, etc. to clean the solar panels. The high-pressure water gun has a good effect on washing dust and leaves on the surface of the solar panel, but it is difficult to clean pollutants such as bird droppings and oily pollutants.

The accumulation of residual pollutants may affect the efficiency of photovoltaic power generation. Therefore, the present application provides a photovoltaic power station cleaning device to meet the needs. Utility Model Content
