Solar photovoltaic array surface cleaning device and control means

Solar photovoltaic array surface cleaning device and control means was presented in this paper. The cleaning device for photovoltaic panels surface which coating self-cleaning film. It was slider hollow tubes with many holes which droved by the high-pressure pump. It was fixed on two unidirectional damping rails completely. The control means used a timer switch to control the high pressure pump. It could completely integrate whole control system which could set and adjust different cleaning times according to different regions, different season and different weather. This design significantly reduced installation costs and maintenance costs.
