[0002] The photovoltaic industry uses photovoltaic power generation panels to convert solar energy into electrical energy. As a clean and renewable energy source, it is of great significance to alleviate the energy crisis and environmental pollution of non-renewable energy sources such as coal and petroleum. It is in line with the national sustainable development strategy to protect the environment and save energy. It is an emerging industry with development potential, but its power generation efficiency is greatly affected by temperature, humidity, light intensity and dust. Long-term accumulation of dust will not only cause serious damage to photovoltaic modules, reduce power generation efficiency, and induce many failures , so regular cleaning and maintenance of photovoltaic modules is an effective way to quickly improve the power generation efficiency of photovoltaic power plants

[0003] At present, the cleaning of photovoltaic modules is mainly carried out by manual dust removal, high-pressure water gun dust removal, and professional cleaning equipment dust removal at home and abroad. However, manual cleaning is easy to cause damage to solar photovoltaic panels, and the efficiency is low. Good, but there is a lot of waste of water resources, and it is difficult to reuse it, which leads to limited practical environment. Using mechanical dust removal technology, using machines to drive brushes, and cleaning photovoltaic panels while sprinkling water, the cleaning efficiency is poor, and mechanical operation is difficult. There are also For example, a photovoltaic module cleaning equipment provided by CN107626631A is a plate-type cleaning equipment with scrapers and brushes installed on the surface of photovoltaic panels, but lacks a cleaning monitoring system, has a low degree of intelligence, and is difficult to perform remote control, fault alarm, and monitoring management. In particular, the impact of rainfall and strong winds on cleaning and dust removal facilities and actions is difficult to control, resulting in low cleaning efficiency and high costs for investigation and use
