Description

Technical Field

[0001] This utility model relates to the technical field of solar panel cleaning devices, and in particular to a solar panel cleaning device. Background Technology

[0002] Driven by the strong global demand for clean energy, the solar energy industry has developed rapidly. As a key device for converting solar energy into electricity, solar panels have seen continuous expansion in installation scale, whether in large-scale solar power plants or distributed rooftop solar systems. However, the surface of solar panels is prone to accumulating dust, dirt, bird droppings, and other impurities. These pollutants can significantly reduce the photoelectric conversion efficiency of solar panels. In large-scale solar power plants in desert areas, frequent sandstorms can quickly cover the surface of solar panels with a thick layer of sand. If not cleaned in time, the power generation efficiency will drop sharply. Therefore, efficient solar panel cleaning devices have become an important requirement to ensure the stable and efficient operation of solar energy systems.

[0003] Currently, solar panel cleaning devices on the market mainly consist of cleaning actuators and power and drive systems. Early solar panel cleaning relied primarily on manual labor. Workers had to use cleaning tools with water or detergent to manually wipe the surface of the solar panels. This method was not only inefficient and labor-intensive, but also posed significant safety risks in large-scale solar power plants due to the long hours of work at height. A medium-sized solar power plant might require dozens of workers spending several days to complete a full cleaning, resulting in high labor costs. Furthermore, relying on natural rainfall to clean solar panels presents numerous uncertainties. In arid regions, natural rainfall is insufficient for cleaning. Even in areas with abundant rainfall, rainwater may not completely wash away stubborn stains such as sticky bird droppings or oil stains. Moreover, long-term reliance on natural rainfall for cleaning can lead to water stains remaining on the surface of the solar panels, affecting their appearance and reducing power generation efficiency. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a solar panel cleaning device, which aims to improve the existing technology. In the medium term, solar panel cleaning mainly relies on manual labor. Workers need to use cleaning tools with water or detergent to manually wipe the surface of the solar panels. This method is not only inefficient and consumes a lot of manpower, but also poses a high safety risk in large-scale solar power plants, as manual cleaning requires long-term high-altitude work.
