Impact of roof orientation on solar savings. The panels can be mounted east west or south facing or in between depending on roof orientation. The s flex leichtmount rail mounting system for framed pv modules is the ideal solution for flat roofs up to a maximum pitch of 5 even with a low load bearing capacity. On a flat roof the solar panels are typically installed on free standing frames that can optimize array performance by providing the ideal tilt and directional orientation.

The mounting frames are not secured to the roof and therefore the system has to be weighted down using ballast.
