Flat Roof Ballasted Solar Racking

Flat Roof Ballasted Solar Racking.

Ballast mounts rely solely on the weight of the array, racking system and additional material, like concrete pavers, to hold the array to the roof. Their biggest advantage is the lack of roof penetrations. This does not eliminate the need for working with a roofing contractor, but it can significantly reduce the coordination required between the roofer and the PV installer. These arrays can generally be installed while maintaining the roof warranty. But in order to do so, the installation must be coordinated with the original roofer or an approved representative for the roofing manufacturer. Ballasted solar racking systems need to be carefully analyzed due to the increased roof loading imposed by the array. Also, many ballasted mounting systems will be limited to a pitch of 20° or less to minimize wind uplift forces.
