How to clean the films?

If HeliaSol® is installed with inclination, no special cleaning is required. The inclination of each rooftop (even flat rooftops have minimum inclination of 1-2 degree) will enable natural cleaning by the rain. It is recommended to clean the solar films if they are covered with dust or dirt since this will affect the power output. Clean the modules with distilled water and a soft, non-scratching cloth.
