    PV panels mounted on roof Workers install residential rooftop solar panels. The solar array of a PV system can be mounted on rooftops, generally with a few inches gap and parallel to the surface of the roof. If the rooftop is horizontal, the array is mounted with each panel aligned at an angle.

    The cost of cleaning depends on what cleaning technique is used and the labor cost at the given location. Furthermore, there is a difference between large-scale power station and rooftop systems . The cost of cleaning of large-scale systems vary from 0.015 euro/m 2 in the cheapest countries to 0.9 euro/m 2 in the Netherlands . [ 1 ]
