Description

technical field [0001] The invention belongs to the technical field of photovoltaics, and in particular relates to an automatic cleaning system and working method for solar photovoltaic panels based on dust thickness detection. Background technique [0002] Solar energy plays an important role in the long-term energy strategy, and both at home and abroad are vigorously developing solar photovoltaic power generation. The areas with the most abundant solar energy resources in my country are mainly northern Ningxia and northern Gansu, but the climate in these areas is dry, and a large amount of dust is deposited on the surface of solar photovoltaic panels, which reduces the output efficiency of photovoltaic panels. The existing dust cleaning method is mainly based on manpower, which is inefficient and consumes a lot of water resources. Contents of the invention [0003] In order to solve the problems of the technologies described above, the technical solution adopted in the ...
