Colorado Solar Rebates: Every Dollar Still on the Table in 2026
Colorado solar rebates in 2026 consist of three active incentives: Xcel Energy's Solar*Rewards program (monthly per-kWh payments for exported electricity), net metering at full retail rates, and Colorado's statewide property tax exemption for solar installations. The federal 30% solar Investment Tax Credit (ITC/25D) expired December 31, 2025, making these utility and state programs the remaining financial incentives for new Colorado solar installations.
What happened to the federal solar tax credit?
The residential solar Investment Tax Credit (Section 25D) -- which offered a 30% credit on installed system costs -- was terminated for systems placed in service after December 31, 2025. Systems that were installed and operational before that date can still claim the credit on 2025 tax returns, but new installations in 2026 do not qualify.
For context: a typical 8 kW Colorado system costs $20,000–$25,000 installed. The now-expired 30% ITC would have saved $6,000–$7,500. With that credit gone, payback periods on cash purchases have lengthened -- but Colorado's strong solar resource, rising electricity rates, and utility programs still support a solid long-term return. The Xcel rate increase filed for August 2026 (+9.9%) actually improves solar ROI by raising the value of every kWh your system offsets.
What utility solar programs are available in Colorado?
Xcel Energy serves most of the Front Range -- Denver, Boulder, Fort Collins, Pueblo, and surrounding areas. Xcel's Solar*Rewards program pays residential customers a per-kilowatt-hour rate for electricity exported to the grid, in addition to standard net metering credits. Payments are made monthly for the enrollment period. Xcel also offers net metering at the full retail rate, so excess solar generation offsets your bill dollar-for-dollar rather than being credited at a reduced wholesale rate.
Black Hills Energy serves portions of southern and southeastern Colorado, including Pueblo and Colorado Springs (partially). Black Hills has its own solar rebate and net metering programs, which differ from Xcel's. If you're in Black Hills territory, confirm your current Solar Rebate program details directly -- rates and enrollment windows change annually.
Municipal utilities -- including Fort Collins Utilities, Colorado Springs Utilities, and Longmont Power and Communications -- each operate independently. Net metering and interconnection policies vary. If you're served by a municipal utility, check its specific solar programs rather than assuming Xcel or Black Hills terms apply.
How does the property tax exemption help solar economics?
Colorado law exempts residential solar energy systems from property tax assessment statewide. This means your assessed home value will not increase as a result of adding solar, so your property tax bill remains unchanged. Solar installations typically add $15,000–$25,000 in appraised home value based on national studies -- an asset you gain without a corresponding tax increase. Over a 25-year system life, the avoided property taxes can represent $3,000–$7,000 depending on your local mill levy.
Putting the full picture together for a typical Colorado homeowner in 2026: a $22,000 installed system earns monthly Solar*Rewards payments from Xcel over the enrollment period, ongoing net metering credits that reduce or eliminate the electricity bill, and no property tax increase despite added home value. Without the federal ITC, payback periods for cash purchases in Colorado currently range from 10 to 15 years, compared to 7–11 years with the now-expired credit. However, the combination of Xcel's pending 9.9% rate increase and Solar*Rewards payments compresses that timeline over the system's life.
Colorado does not have a solar-specific state rebate program. The federal 25C (efficiency) and 25D (solar) tax credits both expired at the end of 2025. The programs described on this page are what is actively available for 2026 installations. When comparing contractor quotes, ask them to confirm which incentives apply to your specific installation date and situation -- and be skeptical of any quote that assumes federal tax credits still apply.

Frequently Asked Questions
Does Colorado have a state solar rebate in 2026?
No. Colorado does not have a state-level solar rebate program in 2026. The federal 30% solar tax credit (25D/ITC) also expired for systems placed in service after December 31, 2025. The incentives that remain active for Colorado solar installations are utility-specific programs (Xcel Solar*Rewards, Black Hills Energy programs) and the statewide property tax exemption. This makes utility programs more important than ever for Colorado solar economics in 2026.
How does the Xcel Solar*Rewards program work?
Solar*Rewards is Xcel Energy's incentive for residential solar customers. Once your system is interconnected with the grid, Xcel pays you a per-kilowatt-hour rate for electricity your system exports. Payments are made monthly throughout the enrollment period. The program rate depends on your enrollment tier and when you joined. Solar*Rewards is available to Xcel customers across the Front Range and most of northern and central Colorado. It operates alongside net metering, not instead of it.
What is net metering and how does it work in Colorado?
Net metering allows your solar system to send excess electricity to the grid in exchange for bill credits at the retail electricity rate. When your panels produce more than you use -- typical on sunny summer days -- the surplus is credited to your account. You draw those credits back in winter or on cloudy days. Colorado requires Xcel Energy and other utilities to offer net metering for residential systems up to 120% of your annual consumption. It is not cash back; it reduces your future electricity bills.
Is solar exempt from property taxes in Colorado?
Yes. Colorado law exempts residential solar energy systems from property tax assessment. Your home's assessed value will not increase due to your solar installation, which means adding solar does not raise your annual property tax bill. This exemption applies statewide and is honored by all Colorado counties. Over a 25-year system life, the exemption can represent several thousand dollars in avoided taxes, since solar systems typically add $15,000–$25,000 in appraised home value.
