Colorado has a mature residential solar market, concentrated in the Denver metro, Colorado Springs and Boulder. Growth has been consistent since Xcel Energy's Solar*Rewards programme established a strong installer base in the 2010s. The 2024 state rebate programme (Solar for Residential) adds a direct cash incentive that has lifted volume meaningfully.

Incentives

State and local solar incentives in Colorado

Beyond the 30 percent federal Residential Clean Energy Credit, which applies in every US state through 2032, Colorado has these state and local programmes.

Colorado Solar for Residential rebate (2024)

State-administered direct rebate for residential solar installations, launched in 2024 under the Colorado Energy Office. Rebate amount scales with household income; up to $8,000 for income-qualified households and smaller amounts for market-rate households. Programme funding is limited and renews annually.

Property-tax exemption

Colorado exempts the added value of residential solar systems from property-tax assessment under CRS 39-3-118.5. Automatic.

Sales-tax exemption

Residential solar equipment is exempt from Colorado's 2.9 percent state sales tax. Local sales taxes may still apply; check with the installer.

Xcel Energy Solar*Rewards (closed to new residential)

The Xcel Solar*Rewards production incentive is now closed to new residential customers but continues to pay out for existing enrollees. New customers rely on retail net metering plus the 2024 state rebate.

Permits and interconnection

Permits and interconnection

Permit timelines in Colorado vary by jurisdiction. Denver, Boulder and the main Front Range cities commonly take 2 to 5 weeks for residential. SolarAPP+ adoption is growing but not universal. Interconnection with Xcel Energy typically runs 3 to 6 weeks post-install.

Running a solar company in Colorado

Running a solar company in Colorado means operating in a mature market with strong fundamentals (good sun, retail NEM, new state rebate) but intense Denver-metro competition. Lead costs on Google Search are moderate to high ($140 to $200 in Denver, lower elsewhere). The installers who have grown fastest know the Solar for Residential rebate programme well and have built it into every proposal; the ones who ignore it lose to competitors who make it visible to the customer.
