Utility-Scale & Commercial Solar PV Calculator

Solar PV array sizing, battery storage capacity (BESS), and load analysis built for commercial and utility-scale projects — not residential rooftop installs.

Scope note. ClarkTE works on commercial solar (school, factory, warehouse, fleet depot scale) and utility-scale solar (typically > 1 MW with formal interconnection studies). For residential rooftop solar — system sizing, panel selection, payback estimates — this calculator will technically work, but you’re better served by a residential-focused tool. We don’t do residential installs.
