Automatic cleaning system for photovoltaic modules

The invention discloses an automatic cleaning system for photovoltaic modules. The automatic cleaning system for the photovoltaic modules comprises an environment monitoring device, a processor and a cleaning device. The environment monitoring device is used for acquiring environment parameters of the photovoltaic modules; the processor is connected with the environment monitoring device and used for generating cleaning control signals according to the environment parameters; the cleaning device is connected with the processor and used for cleaning the photovoltaic modules under control of the cleaning control signals. By the automatic cleaning system for the photovoltaic modules, the problem of low power generation efficiency of the photovoltaic modules due to delay and unsafety in manual cleaning of the photovoltaic modules in the prior art is solved, and timeliness and accuracy in cleaning of the photovoltaic modules are realized to guarantee power generation efficiency and service lives of the photovoltaic modules.
