Installing PV arrays on to an already existing roof structure has become standard these days. A wide variety of mounting systems allow a fast and safe installation of the solar panels – even at high loads from wind or snow – which makes it quite inexpensive to put up such solar generators. They are designed to meet the structural requirements of the of the existing roof construction.
