[0002] A solar photovoltaic panel is a device that directly converts solar energy into electrical energy through the photovoltaic effect. It mainly consists of a series of solar cells made of semiconductor materials (such as silicon). When sunlight shines on the photovoltaic panel, the energy of photons excites electrons in the solar cells, generating an electric current. Solar photovoltaic panels have many advantages. Firstly, it is a clean and renewable energy source that does not produce greenhouse gas emissions or other pollutants and is environmentally friendly; secondly, it can be installed relatively flexibly and can be installed and used in various places such as rooftops, open spaces, and deserts.

[0003] Solar photovoltaic panels are widely used because of their cleanliness and convenience. During their practical use, they need to be cleaned regularly. The main cleaning methods for solar photovoltaic panels are as follows:

[0004] Manual cleaning: Use a soft cleaning tool, such as a clean cloth or sponge, dip it in an appropriate amount of clean water or mild detergent, and gently wipe the surface of the photovoltaic panel; this method is relatively flexible, but may have low efficiency and is inconvenient for operating photovoltaic panels at higher positions.

[0005] High-pressure water gun cleaning: Use a high-pressure water gun to spray water to wash the dirt on the surface of the photovoltaic panel; but pay attention to controlling the water pressure to avoid damaging the photovoltaic panel.

[0006] Professional cleaning equipment: There are robots or automated equipment specially designed for cleaning photovoltaic panels, which can automatically complete the cleaning work, improving efficiency and cleaning quality.
