[0002] As the energy crisis worsens, solar energy as a clean and renewable energy source has attracted much attention. As solar panel power generation technology becomes more and more mature, solar panels have been widely promoted. However, solar panels are directly exposed to the external environment. Over time, a large amount of dust, bird droppings and other debris will adhere to the solar panels, seriously affecting the power generation efficiency of the solar panels.

These areas have inconvenient transportation, scarce precipitation, long-term drought and water shortage, and it is difficult to replenish water resources for cleaning; and water sources evaporate quickly in places with strong sunlight, so using water for cleaning will waste a lot of water resources.
