Description

Technical Field

[0001] The invention relates to the technical field of photovoltaic cleaning equipment, and in particular to an automatic cleaning system for photovoltaic panels. Background Art

[0002] With the rapid development of the solar energy industry, photovoltaic panels, as the core components of solar power generation, are of vital importance for their performance stability and power generation efficiency. However, when photovoltaic panels are operating outdoors, dust, bird droppings, sand and other pollutants are easily accumulated on the surface, which will block the incidence of sunlight, resulting in a reduction in the effective light received by the photovoltaic panels, thereby reducing the power generation efficiency. According to research, if the dust accumulation on the surface of photovoltaic panels reaches a certain level, its power generation efficiency may drop by 20% or even more. Therefore, regular cleaning of photovoltaic panels is a key measure to maintain their performance and power generation efficiency.

[0003] In the past, the cleaning of photovoltaic panels was mainly done manually, which has many shortcomings. First, manual cleaning is labor-intensive and inefficient, and it is difficult to meet the cleaning needs of large-scale photovoltaic power stations. Second, the manual cleaning process may cause scratches or damage to the surface of the photovoltaic panels, affecting their service life. In addition, manual cleaning also has certain safety risks, especially when working at heights, the safety of workers is difficult to guarantee.

[0004] In order to solve the above problems, automatic cleaning devices came into being. The existing automatic cleaning technology solutions for photovoltaic panels have limited adaptability to complex terrains. They can only clean photovoltaic panels at a fixed height, and cannot change the cleaning height or adjust the cleaning angle. The existing automatic cleaning system often has difficulty adapting to these complex cleaning environments, resulting in poor cleaning effects or even no cleaning. Summary of the invention
