☀️ Ballast Block Weight (PSF), Wind Uplift & Building Structural Capacity

Commercial Flat Roof Solar Ballasted Dead Load Calculator

Calculate dead load PSF (pounds per square foot) added by commercial ballasted solar arrays, calculate concrete ballast block count per module to resist ASCE 7-16 wind uplift speeds, and verify building structural reserve capacity.
