Quick Answer
Colorado's 2026 solar incentives include a 100% state sales tax exemption, a residential property tax exemption, a 10% battery tax credit through Form DR-1307, full retail net metering for most utilities, and utility rebates such as Xcel Solar Rewards at $1/W. The federal residential tax credit expired in 2025, but leases and commercial projects may still use Section 48E.
Colorado had roughly 5,687 MWdc of installed solar capacity by early 2026, enough to power more than 1.2 million homes, according to SEIA. For anyone researching solar incentives Colorado, that scale means competitive pricing and plenty of installer experience. The state ranks 15th nationally in cumulative solar and 9th in new additions, with 379 solar and storage companies operating locally.
The incentive story changed on January 1, 2026. The federal Residential Clean Energy Credit under Section 25D expired for homeowner-owned systems. Colorado homeowners can no longer subtract 30% of system cost from their federal taxes. But Colorado still has one of the stronger state-level incentive stacks in the Rocky Mountain region. The state sales tax exemption, property tax exemption, battery tax credit, and utility rebates can offset thousands of dollars in upfront cost.
For installers and EPCs, the shift means proposals must be built around utility territory first. A home in Xcel Energy territory can access a very different rebate stack. A home served by Holy Cross Energy, Colorado Springs Utilities, or a rural cooperative faces a different menu. This guide explains every active 2026 incentive. It also covers the real dollar value of each program and how to model payback accurately. For the national context, see our solar incentives in USA 2026 guide. For payback modeling, SurgePV’s generation and financial tool can pull Colorado utility rates and net metering rules into a single proposal.

Latest Updates: Colorado Solar Incentives 2026
Colorado did not lose its solar incentives in 2026. It lost the federal residential credit. The state and local programs that remain are meaningful, but they are more fragmented than a single national tax credit. Programs also have deadlines, budgets, and eligibility rules that change by utility.
Colorado Solar Incentive Status — June 2026
| Incentive | Type | Status | Key Terms |
|---|---|---|---|
| Federal residential ITC | Tax credit | Expired | Section 25D ended December 31, 2025 |
| Federal Section 48E | Tax credit | Active for commercial/TPO | 30% through 2027 with safe-harbor deadlines |
| Colorado sales tax exemption | Tax exemption | Active | 100% of state sales tax on qualifying solar equipment |
| Colorado property tax exemption | Tax exemption | Active | Added system value excluded from assessment |
| Colorado battery tax credit | State tax credit | Active through 12/31/2026 | 10% of battery cost via Form DR-1307 |
| Xcel Solar Rewards | Utility rebate | Active | $1/W for residential, up to $7,000; pre-approval required |
| Xcel Solar Rewards IQDIC | Utility rebate | Active | $1,000/kW for income-qualified customers, up to $10,000 |
| Xcel PSPS battery rebate | Utility rebate | Active | Up to $10,000 for medical-dependent customers in fire-risk zones |
| Holy Cross WE CARE solar rebate | Utility rebate | Active | $100/kW for systems up to 25 kW |
| Colorado net metering | Export credit | Active | Full retail credit; size cap up to 200% of annual consumption for IOUs |
Key Changes Since 2025
Federal ITC expiration: The 30% residential Investment Tax Credit expired for systems placed in service after December 31, 2025, under the One Big Beautiful Bill Act. Homeowners who buy solar with cash or a loan in 2026 cannot claim it. Commercial, third-party-owned, and leased systems may still qualify under Section 48E, according to IRS guidance.
Battery credit sunset: Colorado’s 10% Residential Energy Storage System Credit is available for tax years 2023 through 2026. The credit expires December 31, 2026, unless the legislature extends it, according to the Colorado Department of Revenue.
Xcel peak-rate shift: Xcel Energy moved its residential time-of-use peak window to 5 PM to 9 PM on weekdays. Solar-only customers who export midday energy at off-peak rates and import during the peak window earn less value per exported kilowatt-hour. This makes battery storage more attractive for Xcel customers than it was under older flat-rate designs.
Key Takeaway
2026 is a utility-territory year in Colorado. The statewide sales tax exemption, property tax exemption, and net metering are durable. The battery tax credit has a hard December 31, 2026 deadline. Utility rebates vary by service territory and often require pre-approval.
Why Colorado’s Solar Market Matters in 2026
Colorado is not the sunniest state, but it is one of the most solar-friendly in the Mountain West. The state receives roughly 300 sunny days per year and 5.6 average daily peak sun hours, based on NREL solar resource data. Combine that with rising retail electricity rates, and solar economics remain strong even without the federal credit.
Market Size and Targets
Colorado had 5,687 MWdc of installed solar capacity and 165,499 solar installations by early 2026, according to SEIA. Solar supplied more than 13% of the state’s electricity. The industry supports more than 8,000 jobs and $10.5 billion in investment. The state is projected to add another 5,429 MW over the next five years.
Utility Rate Snapshot — Spring 2026
The average residential electricity price in Colorado reached 16.54¢/kWh in April 2026, according to the U.S. Energy Information Administration (2026). That is above the long-term national average and well above the 14¢/kWh often used in older payback estimates. Higher rates shorten payback because every kilowatt-hour offset by solar avoids a more expensive grid purchase.
| Utility | Service Area | Approximate Residential Rate (2026) |
|---|---|---|
| Xcel Energy | Denver, Boulder, Fort Collins metro | 15–17¢/kWh |
| Colorado Springs Utilities | Colorado Springs | 14–16¢/kWh |
| Black Hills Energy | Pueblo, Canon City, southeastern CO | 14–16¢/kWh |
| Holy Cross Energy | Vail, Aspen, Garfield, Eagle counties | 13–15¢/kWh |
| Rural cooperatives | Varies by co-op | 12–16¢/kWh |
Colorado Statewide Solar Incentives
Three statewide incentives apply to almost every Colorado homeowner regardless of utility: the sales tax exemption, the property tax exemption, and the battery tax credit. None requires an income test, although the battery credit has a capacity minimum.
Colorado Solar Sales Tax Exemption
Colorado exempts the sale, storage, and use of renewable-energy components from the state’s 2.9% sales and use tax. The exemption covers components used to produce alternating-current electricity. Qualifying components include solar modules, inverters, mounting structures, wiring, control systems, and switchgear, according to the Colorado Department of Revenue (2021).
The exemption applies at the point of sale. On a $20,000 solar installation, the savings are roughly $580 in state sales tax. City and county sales taxes may still apply unless the local jurisdiction has adopted its own exemption. Boulder, for example, offers a city sales and use tax rebate on solar materials and permits.
Colorado Solar Property Tax Exemption
Colorado Revised Statutes § 39-3-102 exempts independently owned residential solar electric generation facilities from property taxation. The exemption covers systems up to 100 kW AC located on residential real property and used primarily for that residence. The added market value of the solar system is not added to the assessed value, so annual property taxes do not rise.
This is a long-term benefit. A $20,000 system might otherwise increase assessed value by the same amount. In a 1% effective property tax jurisdiction, that adds $200 per year in taxes. The exemption avoids that bill. Over 25 years that is $5,000 in avoided taxes, without applying for a rebate.
Colorado Residential Energy Storage System Tax Credit
Colorado allows a 10% state income tax credit for qualifying residential battery storage systems installed in Colorado. The credit applies to battery components, sales tax, and shipping. The system must have a minimum capacity of 3 kWh and is claimed on Colorado Form DR-1307.
A $12,000 battery system returns $1,200 in state tax credit. The credit can be stacked with utility battery rebates. It expires December 31, 2026, unless extended. Homeowners considering storage should plan installation so the system is placed in service before that date.
Net Metering in Colorado
Net metering is the billing rule that determines how much a solar customer gets paid for exports. In Colorado, it remains one of the most valuable ongoing incentives because most utilities credit exports at the full retail kilowatt-hour rate.
How Net Metering Works
Colorado law requires investor-owned utilities and most electric cooperatives to offer net metering to customer-generators. Under the standard arrangement, any excess generation in a month is carried forward as a kilowatt-hour credit on the next bill. Credits offset future consumption at the retail rate. At the end of each calendar year, the customer can choose to roll surplus credits forward indefinitely. The other option is to receive payment at the utility’s average hourly incremental cost, according to DSIRE (2026).
For investor-owned utilities such as Xcel Energy and Black Hills Energy, residential systems may be sized up to 200% of the customer’s average annual consumption. Systems over 10 kW require a second meter to track renewable energy credit production. Small municipal utilities serving fewer than 5,000 customers may set their own rules.
The Oversizing Trap
A system sized to 200% of annual consumption can export a large surplus. But those surplus kilowatt-hours are only worth the year-end avoided-cost rate, which is far below the retail rate. The safer design rule is to size for 90–100% of annual consumption and treat exports as a bonus. This is one reason accurate consumption history matters more in 2026 than in years when a federal tax credit could hide sizing mistakes.
Utility-Specific Rebates and Incentives
Colorado’s most valuable upfront rebates come from utilities, not the state. Eligibility depends on service territory, so the first question for any proposal is: who is the utility?
Xcel Energy Solar Rewards
Xcel Energy’s Solar Rewards program offers residential customers $1 per watt of installed solar capacity. The program requires pre-approval before installation. A typical 7 kW system receives $7,000. In exchange, Xcel claims the renewable energy credits generated by the system for 20 years. The program also pays a small production incentive of $0.005/kWh for systems under 25 kW.
Income-qualified customers and those in Disproportionately Impacted communities can receive an enhanced rebate of $1,000 per kW, up to $10,000 for a 10 kW system. This makes Solar Rewards one of the largest upfront incentives available in Colorado, according to Xcel Energy (2026).
Xcel Energy Battery Programs
Xcel offers several battery pathways. The Renewable Battery Connect program provides upfront incentives and annual grid-participation credits. Standard customers have received $350 per kW, while income-qualified customers have received $800 per kW. The program closed to new applications in February 2026 due to budget exhaustion. Xcel has indicated it may reopen mid-year, according to Independent Power (2026).
The Public Safety Power Shutoff battery rebate offers up to $10,000 for medical-dependent customers in high wildfire-risk zones. Customers must be enrolled in Xcel’s Medical Certification Program or the Colorado Medical Exception Program. They must also live in a Tier 2 or Tier 3 wildfire risk zone.
Holy Cross Energy WE CARE Program
Holy Cross Energy serves Eagle, Summit, Garfield, and surrounding mountain counties. Its WE CARE solar rebate pays $100 per kW for new net-metered systems up to 25 kW. A 7 kW system receives $700. The lifetime cap per member is $30,000. Holy Cross also offers the Power+FLEX battery program, which can pay up to $12,500 for enrolled battery capacity.
Fort Collins Utilities
Fort Collins Utilities offers residential customers a solar rebate of $300 per kW-DC, capped at $1,500. It also offers a battery rebate of $300 per kWh, capped at $6,000. A homeowner who installs solar and storage can combine the two for up to $7,500 in municipal rebates on top of state incentives.
Colorado Springs Utilities
Colorado Springs Utilities offers a renewable energy rebate for residential rooftop solar systems up to 15 kW. The rebate is approximately $0.10 per watt, which works out to roughly $750 for a typical 7.5 kW system. Net metering is also available.
Black Hills Energy
Black Hills Energy offers net metering and, in some territories, income-qualified solar rebates. Income-qualified customers have been eligible for $1 per watt for systems from 0.5 kW to 25 kW. They also receive a production incentive of approximately 3.8¢/kWh for 10 years. Battery rebates of $100 per kWh, up to $1,000, have also been available when storage is installed with solar.
Cost, ROI, and Financing Scenarios
The federal credit expiration made financing structure the most important lever in a Colorado solar proposal. The same system can look very different depending on whether it is purchased with cash, financed with a loan, or leased.
Hypothetical 7 kW System in Denver
Consider a 2,000-square-foot home in Denver served by Xcel Energy. The household uses 9,000 kWh per year and pays an average rate of 16¢/kWh. A 7 kW system is priced at $2.80/W, for a gross cost of $19,600.
| Cost Component | Amount | |---|---|---| | Gross system cost | $19,600 | | Colorado sales tax exemption (2.9%) | -$568 | | Xcel Solar Rewards ($1/W) | -$7,000 | | Net upfront cost | $12,032 | | Estimated first-year production | 9,800 kWh | | First-year utility savings | $1,568 | | Simple payback | 7.7 years | | 25-year savings (undiscounted) | ~$39,000 |
This is a hypothetical example for illustration. Actual production depends on roof orientation, shading, and equipment. The property tax exemption adds further long-term value that is not reflected in the simple payback.
Scenario Comparison by Utility Territory
| Scenario | Gross Cost | Incentives | Net Cost | Est. Payback |
|---|---|---|---|---|
| Xcel Energy, cash purchase, 7 kW | $19,600 | $7,568 | $12,032 | 7–9 years |
| Holy Cross Energy, cash purchase, 7 kW | $19,600 | $1,268 | $18,332 | 10–12 years |
| Fort Collins, solar + battery, cash | $32,000 | $9,568+ | $22,432+ | 9–11 years |
| Lease/PPA, Xcel territory | $0 | Passed to lessor | Monthly payment | Immediate savings, lower lifetime total |
The Xcel customer sees the shortest payback because of the $1/W Solar Rewards rebate. The Holy Cross customer still receives the state sales tax exemption and property tax exemption. But the smaller WE CARE rebate means payback stretches toward 12 years. Fort Collins customers can stack city rebates with state benefits, which improves the economics of solar-plus-storage.
Financing Options
Cash purchase captures every available incentive and produces the highest lifetime savings. It requires the most upfront capital and the highest assumed tax liability for credits that need it.
Solar loan spreads the cost over 10–20 years. The homeowner owns the system and keeps the rebates, but loan interest reduces net savings. In 2026, interest rates are still elevated compared to the early 2020s, so shorter loan terms often produce better lifetime economics.
Lease or power purchase agreement requires no upfront payment. The leasing company owns the system and may claim Section 48E. Savings appear as lower monthly bills from day one, but the homeowner does not receive the sales tax exemption, property tax exemption, or utility rebates directly. Leases make sense for customers with limited tax appetite or cash flow, but they surrender long-term value.
RENU Loan Program is offered through the Colorado Clean Energy Fund in partnership with state credit unions. It provides competitive-rate financing for solar, batteries, and related energy upgrades. It is not a rebate, but it can lower borrowing costs compared to unsecured personal loans.
Third-Party Ownership and Section 48E
Commercial projects and third-party-owned residential systems can still claim the 30% Clean Electricity Investment Credit under Section 48E. To qualify, construction must begin by July 4, 2026, or the system must be placed in service by December 31, 2027. This is why lease and PPA providers can still advertise lower payments in 2026: they own the system and capture the credit.
Common Mistakes and How to Avoid Them
Colorado’s incentive stack is generous but easy to mishandle. The most expensive errors are usually paperwork or sizing mistakes, not equipment choices.
Assuming the Federal Tax Credit Still Exists
Many homeowners still expect a 30% federal credit. For cash or loan purchases placed in service after December 31, 2025, it is gone. Proposals should lead with the net cost after state and utility incentives, not a federal credit that no longer applies.
Applying After Installation
Xcel Solar Rewards and many battery programs require pre-approval. Installing first and applying second can disqualify the project. The safe workflow is: pre-approve the rebate, install, interconnect, then claim the incentive.
Oversizing Beyond 200% of Consumption
A system that produces far more than the household uses leaves value on the table. Year-end surplus is settled at the utility’s avoided-cost rate, not the retail rate. Size for 90–100% of annual consumption unless the customer plans to add an electric vehicle or heat pump.
Ignoring Time-of-Use Rates
Xcel’s peak window is now 5 PM to 9 PM. Solar-only systems export most of their energy before the peak. A battery that stores midday solar and discharges during peak hours can replace grid imports at 25–35¢/kWh instead of exporting at off-peak rates. For Xcel customers, storage is often the difference between a good project and a great one.
Missing the Battery Credit Deadline
The 10% Colorado battery tax credit expires December 31, 2026. Systems must be installed and placed in service before that date. Waiting until late 2026 risks supply-chain or permitting delays.
Commercial and Agricultural Considerations
Commercial and agricultural customers in Colorado have additional tools. The Section 48E credit can cover 30% of project cost for projects that meet the construction or placed-in-service deadlines. Businesses can also use MACRS depreciation, which front-loads tax deductions over five years.
Rural small businesses and agricultural operations may qualify for USDA REAP grants and loan guarantees. REAP can cover up to 50% of project cost, but applications must be submitted before construction begins. This makes early planning critical.
For commercial project modeling, SurgePV’s solar design software can size arrays, run shade analysis, and export production and financial reports. The solar proposals feature can package the incentive stack into a client-ready document.
Frequently Asked Questions
What solar incentives are available in Colorado in 2026?
Colorado offers a 100% state sales tax exemption on solar equipment and a residential property tax exemption. It also offers a 10% state income tax credit for qualifying batteries via Form DR-1307. Other benefits include full retail net metering for most utilities and utility rebates such as Xcel Solar Rewards at $1/W. Local programs from Holy Cross Energy, Fort Collins Utilities, Colorado Springs Utilities, and Black Hills Energy may also apply.
Is the federal solar tax credit still available in Colorado in 2026?
No. The 30% federal Residential Clean Energy Credit under Internal Revenue Code Section 25D expired for homeowner-owned systems placed in service after December 31, 2025. Commercial projects and third-party-owned residential systems may still qualify under Section 48E. Eligible projects must begin construction by July 4, 2026, or be placed in service by December 31, 2027.
Does Colorado have a state solar tax credit for solar panels?
No. Colorado does not offer a statewide income tax credit for residential solar photovoltaic systems. The only state tax credit is the 10% Residential Energy Storage System Credit for qualifying batteries, claimed on Colorado Form DR-1307. Solar panels benefit instead from the state sales tax exemption and property tax exemption.
How does net metering work in Colorado in 2026?
Colorado requires investor-owned utilities and most electric cooperatives to offer net metering. Customer-owned systems up to 200% of annual average consumption receive full retail-rate kilowatt-hour credits for exports. Credits roll over month to month. At year-end, customers can roll surplus credits forward or receive payment at the utility’s average hourly incremental cost.
How much is the Xcel Energy Solar Rewards rebate in Colorado?
Xcel Energy’s Solar Rewards program pays residential customers $1 per watt of installed solar capacity, up to $7,000 for a typical 7 kW system. Income-qualified customers and those in Disproportionately Impacted communities can receive an enhanced rebate of $1,000 per kW, up to $10,000 for a 10 kW system. Pre-approval is required before installation.
Are solar batteries incentivized in Colorado in 2026?
Yes. Colorado offers a 10% state income tax credit for qualifying residential battery systems through Form DR-1307, available through December 31, 2026. Xcel Energy also offers battery incentives, including the Public Safety Power Shutoff battery rebate up to $10,000 for medical-dependent customers in high wildfire-risk zones.
Will solar increase my property taxes in Colorado?
No. Colorado Revised Statutes § 39-3-102 exempts independently owned residential solar electric generation facilities from property taxation. The added value of a qualifying system is not included in the property’s assessed value, so property taxes do not increase because of solar.
What is the typical solar payback period in Colorado in 2026?
Payback periods for well-designed residential solar systems in Colorado typically range from 8 to 12 years in 2026. Xcel Energy customers who qualify for Solar Rewards often see paybacks at the shorter end of the range. Customers of cooperatives or municipal utilities without upfront rebates may see longer paybacks.
Can I lease solar in Colorado and still get incentives?
Leases and power purchase agreements do not pass state or utility incentives to the homeowner. The leasing company owns the system and may claim commercial tax benefits such as Section 48E, which are reflected as lower monthly payments. Homeowners who want the sales tax exemption, property tax exemption, and utility rebates should purchase the system with cash or a loan.
What is the most common mistake when applying for Colorado solar incentives?
The most common mistake is waiting until after installation to apply. Xcel Solar Rewards and many utility battery programs require pre-approval. Another frequent error is oversizing beyond 200% of annual consumption. That can leave export value on the table because year-end surplus is settled at avoided-cost rates rather than retail rates.
Bottom Line
Colorado solar in 2026 is still a strong investment, but the decision is no longer driven by a single federal tax credit. The best projects stack the state sales tax exemption, property tax exemption, and utility rebates with accurate consumption-based sizing.
Three actions will put you ahead:
- Confirm your utility territory first, because rebate value varies by service area.
- Apply for utility rebates before installation; many programs require pre-approval.
- Model storage if you are in Xcel Energy territory, where time-of-use rates reward shifting solar into the evening peak.
For installers, accuracy is the new competitive advantage. SurgePV’s generation and financial tool lets you pull Colorado utility rates, net metering assumptions, and incentive values into one proposal. Book a demo to see how it works, or check pricing for your team.
