Solar Panels in Colorado: Cost, Payback & ROI (2026)
Is solar still worth it in Colorado after the 30% federal tax credit expired? These pre-computed estimates use NREL PVWatts production data and current 14.2¢/kWh Colorado electricity rates for a typical home using 900 kWh/month.
Section 25D (30% federal solar tax credit) expired December 31, 2025
All numbers below reflect 2026 math with no federal residential credit. State incentives, where applicable, are noted in the section below.

Is Solar Worth It in Colorado in 2026?
Colorado's 14.2¢/kWh rate and 1,650 kWh/kW/year solar resource make it one of the stronger markets in the Midwest/Mountain region. Xcel Energy serves the Denver metro and offers its own rebate programs. Rural cooperatives have less favorable net metering policies. Colorado's high altitude increases solar panel productivity compared to sea-level locations at the same latitude.
For a typical Colorado home consuming 900 kWh per month, our calculation shows a 6.5 kW system needed for 100% offset. At the current national average installed cost of $2.95/W (LBNL Tracking the Sun 2024), that's $19,309 gross before any state rebates. Year-one savings of $1,534 grow each year as electricity rates escalate — the model assumes 2.5%/year (EIA AEO 2024).
The 11.3 years payback period is moderate — within the national average range of 8–12 years. Over 25 years — the standard warranty period for most premium panels — a Colorado homeowner following this profile would save an estimated $49,043 total, for a net benefit of $29,734 after recovering the system cost.
