Solar Panel Cost in Denver, CO (2026 Estimate)

ByIndependent solar research and calculators

Data last updated

Denver averages about 5.5 peak sun hours a day (well above the national average, matching the Colorado statewide average), and pairs with Colorado's approximate residential rate near 15ยข/kWh. In the model used here, an 8 kW system produces roughly 12,850 kWh a year and trims about $1,900 off annual electricity costs, paying back its net cost in about 8.7 years . Local shading, roof, and your utility's export terms move the real figure.

Estimated system cost and payback in Denver

Costs assume roughly $3.00/watt installed; the net column applies a 30% federal credit for comparison with quotes that include it. Savings use Denver's sun hours and Colorado's rate.

Modeled solar cost, production, savings and payback in Denver by system size
System size Gross cost Net after 30% credit Yearly production Yearly savings Payback
6 kW $18,000 $12,600 9,640 kWh $1,400 8.7 yrs
8 kW $24,000 $16,800 12,850 kWh $1,900 8.7 yrs
10 kW $30,000 $21,000 16,060 kWh $2,400 8.7 yrs

The 30% federal Residential Clean Energy Credit ended for systems paid for after December 31, 2025 under the 2025 federal budget law. Net-after-credit figures apply only if you still qualify (for example a 2025 expenditure, or a leased system where the installer passes a credit through). Confirm with a tax professional.

Net metering and utilities around Denver

Colorado requires its investor-owned utilities, Xcel Energy and Black Hills Energy, to offer retail-rate net metering, and cooperatives and municipal utilities must offer a version of it as well. Excess kilowatt-hours from a sunny month roll forward as credits, and Xcel customers choose between letting credits roll indefinitely or cashing out the balance once a year at an avoided-cost rate. Systems are generally limited to about 120 percent of the home's annual consumption, so oversizing for a future electric car has to be justified up front.

Xcel Energy serves Denver, Boulder, the northern Front Range and Grand Junction, roughly two thirds of the state, while Black Hills Energy serves Pueblo and parts of southern Colorado at noticeably higher rates. Colorado Springs Utilities, Fort Collins Utilities, Longmont and Loveland run municipal systems, and cooperatives including United Power, CORE Electric, Holy Cross, Poudre Valley and La Plata serve suburban and mountain communities. Xcel's default residential rate is time-of-use with a weekday afternoon peak that is much more expensive in summer, and it carries a monthly service charge that solar cannot offset. Municipal and co-op rates are often flat and somewhat cheaper, so payback periods vary widely across the state even for identical roofs.

Sources and methodology

Every figure on this page is computed from two published inputs (average peak sun hours and the state's average residential electricity rate) plus the documented assumptions on the methodology page. It is a transparent model, not a survey of installer quotes. Inputs last reviewed .
