Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of photovoltaic power generation, and particularly relates to an automatic cleaning device for a photovoltaic panel. BACKGROUND

[0002] A photovoltaic panel is a device that converts solar energy into electrical energy, and is usually composed of photovoltaic cells made of semiconductor materials such as silicon. The main function of the photovoltaic panel is to absorb sunlight and convert it into direct current, and then convert it into alternating current through an inverter for use.

[0003] During use of the photovoltaic panel, the photovoltaic panel is exposed to the outside world and sunlight for a long time, and a large amount of impurities will adhere to the surface of the photovoltaic panel. Too much accumulation of impurities on the surface of the photovoltaic panel will reduce the light-receiving area of the photovoltaic panel and affect the use effect and conversion efficiency of the photovoltaic panel. Therefore, the photovoltaic panel needs to be cleaned regularly.

[0004] In the prior art, case one is to use a cleaning tool to scrub and clean the surface of the photovoltaic panel by manual operation. Although the manual cleaning is simple to operate and low in cost, when the number of photovoltaic panels is large and the scale is large, the manual cleaning has the following disadvantages: large workload, high labor intensity, and high labor cost. In addition, the dust accumulated on the surface of the photovoltaic panel has become hard and deeply adhered after a long time of accumulation, and needs to be continuously wiped by the staff using a mop to clean it completely. Case two is to install an automatic cleaning device on the photovoltaic panel. The automatic cleaning device solves the problems of large workload and high labor cost, but when the number of photovoltaic panels is large, the automatic cleaning device consumes a large amount of purchase funds, and the automatic cleaning device itself also needs regular maintenance, which further increases the working cost, and sometimes has the opposite effect. In view of the above, it is expected to design an automatic cleaning device for a photovoltaic panel which is operated by staff, portable, simple and practical, and low in cost. SUMMARY
