The invention relates to a photovoltaic module cleaning operation system. The photovoltaic module cleaning operation and maintenance system networking and intelligent control method includes a cloud server monitoring platform, at least one intelligent controller and at least one environment monitoring device, at least one cleaning operation and maintenance device. The starting and stopping time and the operation and maintenance interval time of the cleaning operation and maintenance device are set on the intelligent controller through the cloud server monitoring platform, and the intelligent controller adjusts starting and stopping of the cleaning operation and maintenance device according to the environment monitoring device. According to the invention, the cleaning operation and maintenance device of the photovoltaic power station is directly divided into multi-level intelligent control, and the all-weather unmanned intelligent control of the cleaning operation and maintenance equipment is completed, and the starting and stopping of the cleaning operation and maintenance device are controlled intelligently according to requirements and by combining the power station environment and the meteorological information; the risk of damage to the photovoltaic module in the cleaning process is reduced; the operation safety and reliability of the cleaning operation and maintenance device are improved, the operation and maintenance cost is reduced, and the cleaning efficiency and the cleaning effect are improved.
