Note: Solar arrays are typically Seismic Design Category A-C. Ground-mount arrays use R=2.5 (non-building structures). SDS values come from USGS seismic hazard maps.

Reference

Cs = SDS / (R/Ie) (ASCE 7-22 Eq 12.8-2) Cs_min = 0.01 (ASCE 7-22 Eq 12.8-5) Base Shear V = Cs × W Overturning M = V × height R = 2.5 for non-building structures (solar)
