Flat Roof Solar Installations
Ballasted Solar Installations
For flat roof installations, where the load-bearing capacity of the roof is sufficient to handle the weight of a solar array, which generally ranges from 4-7 lbs per square foot, a ballasted solar racking option may be appropriate.
Mechanically Fastened Racking
If your flat roof cannot handle the load of a ballasted solar array, a mechanically fastened racking solution may be the best option.
