Description

Technical Field

[0002] Photovoltaic power generation module power supply is a power supply component that arranges multiple photovoltaic panels neatly in a flat or diagonal manner in a photovoltaic power station. Photovoltaic power station refers to a photovoltaic power generation system that uses solar energy and special materials such as crystalline silicon panels, inverters and other electronic components to connect to the power grid and transmit electricity to the power grid. There are many factors that affect the efficiency of photovoltaic panels in converting solar energy, among which dust coverage is the factor that has the greatest impact on power generation efficiency. In photovoltaic power stations, photovoltaic panels that are laid flat or diagonally in an open-air environment are easily covered by pollutants such as dust. In addition to affecting the conversion efficiency of photovoltaic panels, the accumulation of dust will also cause uneven temperature of photovoltaic panels, thereby causing damage to photovoltaic panels.

[0003] At present, the main ways to clean photovoltaic panels include sweeping robots, vehicle-mounted sweepers, and water truck flushing. These solutions may have complex equipment structure and high investment and development costs, or require a lot of manpower and have low cleaning efficiency, or have difficulties in using electricity and fetching water, and have poor adaptability to photovoltaic power station conditions. Therefore, providing an automatic cleaning robot that can be easily installed in a photovoltaic power station, has good adaptability, and can autonomously and efficiently clean photovoltaic panels is a technical problem that needs to be solved at present.
