We usually use soft bristled brushes or sponges to clean solar panels, and we use sponges to clean the surface of solar panels appropriately; If the solar panel is on the roof, we will use a soft bristled brush to clean it appropriately. Usually, factories install an appropriate amount of working modules on the surface of solar panels, so we should avoid using tools that can scratch the surface of the solar panels, thereby reducing the performance of the solar panels.

With the passage of time, there will be a large amount of pollutants on the surface of solar panels, which will reduce the efficiency of solar panel operation. So we need to clean the solar panels as necessary. Usually, we use distilled water or deionized water to clean the pollutants on the surface of the solar panels, because the ions in the water can cause unnecessary damage to the solar panels.
