Calculation of power generation of photovoltaic array Annual power generation = (kWh) = local annual total radiant energy (KWH/㎡) × area of photovoltaic square (㎡) × module conversion efficiency × correction factor. P=H·A·η·K Correction coefficient K=K1·K2·K3·K4·K5.

Solar structural design calculations evaluate whether a roof or ground-mount structure can safely support a photovoltaic system by analyzing dead loads (2–4 psf for panels and racking), live loads, wind uplift per ASCE 7-22, snow accumulation, and seismic forces – then comparing.
