How Much Ballast For Flat Roof Solar?

Ballasted mounting systems for flat roof solar installations rely on weight to resist wind uplift without penetrating the roof membrane. Typical photovoltaic (PV) dead loads are between 3-5 lbs/ft2 (14-24 kg/m2), while most installations require between 5-7 lbs/ft2 (24-34 kg/m2). In light wind ar...
