Solar Panels in Colorado:
Is It Worth It in 2026?

Colorado averages 1537.3 kWh per kWp per year with 5.5 peak sun hours per day. At 16.44¢/kWh, an 8 kW system saves roughly $2,022/year and pays back in about 7.5 years.

💡 Denver's altitude (5,280 ft) means thinner atmosphere and stronger UV — solar panels produce ~10% more electricity than at sea level for the same sun hours.

Solar in Colorado: Frequently Asked Questions

Does Colorado's altitude help solar panels produce more electricity?
Yes — Denver's altitude of 5,280 feet means thinner atmosphere, less air mass to filter sunlight, and stronger UV radiation. This results in approximately 8–12% higher solar output compared to sea-level cities with similar cloud cover and latitude. Denver's combined sunshine and altitude make it one of the top solar cities in the US.
What is Xcel Energy's Solar*Rewards program in Colorado?
Xcel Energy's Solar*Rewards program pays solar owners a per-kWh payment for electricity produced for up to 15 years. Rates depend on system size and when you enrolled, typically $0.07–0.09/kWh. This is paid in addition to net metering credits, providing dual income streams for Xcel customers with solar.
Does Colorado have a solar tax credit?
Colorado does not have a state income tax credit specifically for residential solar. However, solar equipment is exempt from sales and use tax, saving 2.9% (state) plus any local sales tax. Colorado Springs Utilities and Xcel Energy also offer rebates, and all Colorado residents qualify for the state solar incentives (federal ITC expired Dec 2025).

Going Solar in Colorado: Step by Step

From first quote to first kilowatt — here is the typical timeline for a residential solar installation in Colorado. Most homeowners complete this process in 6–12 weeks.

  1. 1
    Get 3 quotes

    Prices in Colorado average $22,400 for an 8 kW system before incentives. Getting three quotes typically saves 10–15%. Use the same system size so you can compare apples to apples.

  2. 2
    Review your electricity bill

    Your last 12 months of usage determines the right system size. At 16.44¢/kWh in Colorado, a system that offsets 90% of your bill hits the best cost-per-kWh sweet spot.

  3. 3
    Check state incentives

    Colorado does not have a statewide solar tax credit, but utility rebates and net metering may still apply. Xcel Solar*Rewards ($0.07–0.09/kWh × 15 yrs).

  4. 4
    Sign contract & apply for permits

    Your installer pulls the building permit and files interconnection paperwork with your utility. Permit approval in Colorado typically takes 1–4 weeks depending on your county.

  5. 5
    Installation day

    A standard 8 kW residential installation takes 1–2 days. Racking goes on first, then panels, then the inverter is wired to your main panel. The crew usually keeps the power on throughout.

  6. 6
    Utility inspection & interconnection

    After installation your utility inspects the system and approves grid connection. This final step can take 1–3 weeks. Once approved, your meter tracks both import and export.

Data summary for Colorado: Colorado averages 1537.3 kWh/kWp/year with 5.5 peak sun hours/day. Electricity costs 16.44¢/kWh. An 8 kW solar system saves ~$2,022/year and pays back in 7.5 years. Xcel Solar*Rewards ($0.07–0.09/kWh × 15 yrs), sales tax exemption.
