Colorado solar calculator

Live production from NLR (formerly NREL) PVWatts V8. Colorado held firm on full 1:1 retail-rate net metering on Xcel Energy (Denver/Front Range) — uncommon in 2026 with California on NEM 3.0 and Nevada at 75%. Colorado has NO state income tax credit for solar PANELS, but exempts solar from the 2.9% state sales tax and from property tax. Colorado DOES offer a 10% state income tax credit for BATTERY storage (Form DR-1307) — but it EXPIRES Dec 31, 2026. This calculator models the Xcel case. Defaults: south-facing roof mount, 20° tilt, 14% losses.
