[0002] Solar cells can be encapsulated and protected after being connected in series to form large-area solar cell modules, and then combined with components such as power controllers to form a photovoltaic power generation device. A photovoltaic panel is a device that directly converts solar energy into electrical energy using the photovoltaic effect that occurs in semiconductor materials under illumination conditions. It is the most direct of many solar energy utilization methods, and most materials are silicon. Electricity can be generated wherever there is sunlight. Therefore, solar photovoltaic power generation is applicable to various scenarios, from large power stations to small portable chargers.

[0003] However, although the reserves of solar energy are very large, the proportion of electrical energy generated by humans using solar energy in the total global energy consumption is still quite small, only about 0.16%. Therefore, actively developing low-cost and high-efficiency solar cell panel materials and improving the photoelectric conversion efficiency will help solve the world energy and environmental crises and have great practical value and significance.

[0004] After long-term use, the surface of a photovoltaic power generation panel is likely to be contaminated with dust. In the case of a large amount of dust, it will affect the use of the photovoltaic power generation panel.

When in use, most of them clean the photovoltaic panel through multiple steps of spraying water, cleaning, and scraping, making the device rather troublesome to use and affecting the cleaning efficiency. To address the above problems, a portable photovoltaic cleaning device is needed. Summary of the Utility Model
