A super-hydrophobic coating sprayed on the glass surface as well as mono crystalline silicon solar panel surface to form a layer of super-hydrophobic water film on the coated surface, The functional material in the super-hydrophobic coated film forms some waxy particles on the surface of the coated glass, This "lotus effect" causes stains to be peeled off the glass surface, which reducing the dirt and the contact area of rain on the glass, So that the
adhesion of dirt is not strong, the rain can not be attached, just to use the erosion of the natural rain, the Water droplets can be washed down and wrapped with dirt under the action of gravity , it could clear the dirt and can not be attached with rain, so that the glass surface will be dry and clean.
