The edges of PV module surface with inclined angle are easy to accumulate dust. The glass surface coating of the module is damaged after a long time, which seriously affects the light transmission of the module. Dust drainage clips can help to solve this problem very easily!
Solar panel cleaning clip is a rectangular self-adhesive strip made of polymer. Just bulckle it up to the frame of the photovoltaic module is ok. When it rains, it will automatically guide the mud water accumulated at the lower edge of the frame over the frame and flow out.
