Solar in Colorado costs about $3.02 per watt, so the 7.00 kW system Colorado homeowners typically install runs about $21,140 before incentives. Your utility matters more than that price: Xcel, Black Hills, Colorado Springs Utilities and the co-ops each credit your power, and your surplus, in their own way.

Five Colorado utilities, five different deals for your solar
Colorado has the most fragmented home solar economics in the region. Panel brand and installer matter less than one question: who sends your power bill?
Under C.R.S. §40-2-124. The RE-TOU rate since November 1, 2025, plus a $7.10 service and facility charge. Ask Xcel for today’s on-peak and off-peak prices.
Exports net one for one, month to month. Only kWh left at year end earn its year-end payment rate, unless you elect in writing to roll them forward. Get the rate in writing.
Exports net one for one at retail and carry month to month. Year-end surplus earns the cogeneration rate unless you elect rollover.
Full retail net metering. The January 2026 rate rise makes each solar kWh worth more.
The WE CARE rebate, up to 25 kW, effective April 1, 2026. It covers panels and storage.
Co-op net metering under C.R.S. §40-9.5-118 keeps full retail credit for exports up to the system load.
Size to a year of use, not your roofEvery utility here pays the low rate only on surplus left at year end. A system sized to your annual use keeps nearly all its export value, even if it exports by day and draws from the grid at night.
Colorado Springs Utilities is changing its termsCSU has proposed new net metering rate options for agreements dated April 1, 2027 or later, with a daily grid access charge or a demand charge. City Council approved the change on September 22, 2026. Existing customers keep current rates until April 1, 2032.
The typical 7.00 kW system, from price to payback
A cash buyer in 2026, with no federal credit. The 7.00 kW size is the median Colorado homeowners installed in 2025 (Berkeley Lab, 6,702 systems).
7.00 kW system at $3.02 per watt
Elsewhere: on the same cash price and one-for-one credit, Black Hills pays back in about 10.5 years, CORE Electric in about 12.5 and Colorado Springs Utilities in about 14.8, each at its own price with its fixed charge taken out. These figures count no upkeep and no price rises. Holy Cross WE CARE members also get the $100 per kW rebate, which shortens the payback there. Test the long run in whether the long-term return still works in Colorado.
A rate increase helps solar owners twiceXcel filed a residential rate case, Proceeding 25AL-0494E, in 2025. If the Colorado PUC approves higher rates, your export credit rises with retail, and so does the power you avoid buying.
Xcel time-of-use and a batteryOn RE-TOU, a battery shifts evening grid use out of the on-peak window. Homes with heavy daytime air conditioning and no battery gain less than on the flat rate.
What Colorado installers quote, 6 kW to 12 kW
The EcoGen Index puts Colorado at $3.02 per watt, $0.13 above the $2.89 US average and tied 37th lowest of 51. Competitive Colorado installers quote a working range of $2.69 to $3.41 per watt, so most systems land between $16,100 for 6 kW and $40,900 for 12 kW. See where that sits in our state-by-state solar pricing.
Quote ranges use the $2.69 to $3.41 per watt working band, for a code-compliant rooftop install with hail-rated modules. The battery figures add one 13.5 kWh Tesla Powerwall 3 or comparable LFP unit at $13,500 installed.
Why other price reports run higherMarketplace aggregators include premium financing and high-overhead bidders. Berkeley Lab’s Tracking the Sun 2024 puts the national median at $4.00 per watt, a figure that includes lease and PPA pricing and high-cost regions.
Why marketplace systems look biggerSystems sold through marketplaces in Colorado average 10 to 11 kW. The shoppers who reach them tend to have higher bills, electric vehicles or plans to electrify.
Hail, roof age and a $500 permit cap: what moves a Colorado price
Three Colorado pressures sit under the per-watt number. Two push it up. One pulls it down.
+What pushes a Colorado quote up
- Hail-rated modulesAsk for the panel’s hail rating and a warranty that names hail.
A small premium, and the cheapest insurance in the project - An aging roofIf the roof will need replacing during the panels’ life, replace it first or budget for a detach and reset. Ask your insurer how it treats an older roof under panels.
$1,000 to $15,000
−What holds Colorado prices down
- A $500 cap on permit feesState law caps residential solar permit fees at $500.
- Fast approvalsDenver, Bennett, Wheat Ridge, Alamosa and Gilpin County use SolarAPP+ for near-instant approval. Other cities take 2 to 4 weeks. That trims soft costs slower states like Massachusetts and New York carry.
- No sales tax on solarThe 2.9% state sales tax exemption, C.R.S. §39-26-724.
- No property tax bumpUnder C.R.S. §39-1-102(6.8), solar does not raise your home’s assessed value.
After §25D: the Colorado credits and rebates still paying
The 30% federal credit is gone for systems you ownThe One Big Beautiful Bill Act (Public Law 119-21), signed July 4, 2025, ended §25D for systems installed after December 31, 2025 (IRS Fact Sheet 2025-05). That is a $5,400 to $9,100 swing on a 6 to 10 kW system against a 2025 install. A lease or PPA provider may still claim the §48E credit, not you. A project that starts construction after July 4, 2026 must be in service by December 31, 2027 to qualify.
Saves $500 to $1,200 on the equipment.
The install does not raise your home’s assessed value.
An upfront rebate for Income-Qualified and Disproportionately Impacted Community customers. Standard customers get $0.005 per kWh for systems under 25 kW.
The Residential Energy Storage Tax Credit, through 2026, on Form DR-1307. Only the owner can claim it.
For panels and storage, up to 25 kW.
Golden pays $3,000 for panels plus $3,000 for a battery. Boulder rebates sales and use tax. Fort Collins has a tiered rebate by system size and income.
See current amounts by program in the full breakdown of Colorado solar incentives.
Xcel’s battery program is closed for nowRenewable Battery Connect paid $350 per kW, up to $5,000, in 2025. Enrollment closed February 20, 2026, with a possible reopening mid 2026.
Cash, a solar loan or a lease: paying for a Colorado system
Cash gives the shortest payback. A lease is the only way left to reach a federal credit.
Pay cash
You own the system
Upfront
About $21,100 for the typical 7.00 kW at $3.02 per watt.
Monthly
Nothing. At Xcel’s price, the typical system saves about $1,739 a year.
Credits
Sales and property tax exemptions, plus the 10% battery credit if you add storage.
Watch out for
No federal credit softens the check.
Pays off in about 12.2 years at Xcel, then years of net savings.
Solar loan
You own the system
Upfront
Often little or nothing, through registered Colorado contractors.
Monthly
Payments over 15 to 25 years.
Credits
The same state exemptions as cash.
Watch out for
A dealer fee rolled into the contract price.
Cash or a HELOC works out cheaper if you have the option.
Lease or PPA
The provider owns the system
Upfront
$0. Palmetto’s LightReach is the most visible offer in Colorado.
Monthly
A monthly payment or a price per kWh.
Credits
The provider claims §48E and passes part of it on as a lower payment. No state battery credit for you.
Watch out for
A 2.9% yearly escalator about doubles the payment by year 25.
No upfront cost, but the escalator may outpace utility rates.

Five Colorado cases where solar fails the payback test
Skip or rethink solar if one of these describes your home:
- You size past a year of use. Year-end surplus earns only avoided cost: about 2¢ per kWh at Colorado Springs Utilities and 1.529¢ (2023) at Xcel. Right-size instead.
- Your roof is near the end of its life. Roof work may push total cost past the payback window.
- Heavy shade in the foothills. Mature ponderosa or aspen canopy cuts output 25% to 40%. Xcel’s Solar*Rewards pays nothing then, and the math fails even at $3.02 per watt.
- You may sell within 5 years. A sale price rarely recovers a fresh install. Solar pays through years of lower bills.
- Your co-op power is very cheap. In San Luis Valley REC or Highline Electric territory, rates can sit under 11¢ per kWh. That rarely justifies a $21,100 system unless storage, an EV or a heat pump is coming.
Five questions that sort Colorado installers
Colorado law requires DORA electrical contractor registration and a master electrician on staff. Ask about both, then these:
- Can you show your DORA electrical contractor registration and your master electrician?
- Are you a member of the Colorado Solar and Storage Association (COSSA)? Membership is no guarantee, but no trade affiliation at all is a signal.
- What is the module’s hail rating, and does the warranty name hail?
- Does my jurisdiction use SolarAPP+, and how will you permit my job?
- Will you give me a written roof assessment with a remaining-life estimate? If it will need replacing during the panels’ life, ask for a separate detach and reset quote.
NABCEP certification is the strongest individual installer credential, though the state does not require it. See vetted Colorado solar installers worth quoting.

Frequently asked questions
How Much Do Solar Panels Cost in Colorado in 2026?
A 6 kW residential system costs $16,100 to $20,500 gross at competitive Colorado installers in 2026. A 10 kW system runs $26,900 to $34,100. The EcoGen Index puts Colorado at $3.02 per watt, and installers quote a working band of $2.69 to $3.41. Marketplace aggregators report higher numbers because their averages include premium financing and high-overhead bidders.
Can I Still Get the 30% Federal Solar Tax Credit in 2026?
Not for an owner-purchased system. The One Big Beautiful Bill Act, signed July 4, 2025, ended the §25D residential credit for systems installed after December 31, 2025. The §48E commercial credit still reaches Colorado homeowners who sign a lease or power purchase agreement (PPA), where the installer claims the credit and passes the savings through as lower monthly payments. A project that starts construction after July 4, 2026 must be in service by December 31, 2027.
How Does Xcel’s Pending Rate Increase Change My Solar Payback?
Xcel filed a residential rate case, Proceeding 25AL-0494E, in 2025, and the Colorado Public Utilities Commission decides what it approves. A higher retail rate shortens solar payback because the export credit and the avoided purchase value both rise with retail rates.
Will Solar Work on a Colorado Home in Hail Country?
Yes, with hail-rated modules. Ask for the panel’s hail rating and a warranty that names hail, and confirm with your insurance carrier that the panels are covered after the install.
Does My Homeowners Insurance Need to Change When I Add Solar?
Notify the carrier before the install. Ask whether your policy covers roof-mounted solar as part of the dwelling or needs a rider for the equipment, and how it treats your roof’s remaining life.
What’s the Catch With Colorado Springs Utilities Net Metering?
CSU credits exports one for one at retail and carries surplus kilowatt hours month to month; the catch is the year-end surplus, credited at the cogeneration rate of about 2¢ per kilowatt hour unless you elect rollover, and a proposed rate change. City Council approved new net metering rate options on September 22, 2026. They apply to agreements dated April 1, 2027 or later. Existing customers keep current rates until April 1, 2032. Size to your annual usage and get your agreement dated before the change takes effect. Right-sizing matters more than battery sizing in CSU territory.
Do I Need to Replace My Roof Before Going Solar in Colorado?
If your roof will need replacing during the panels’ life, plan on either a full replacement before solar or a detach and reset later. Ask your insurer how it treats an older roof under panels. A detach and reset can fall within the $1,000 to $15,000 roof-work range. A roof replacement plus solar in one trip avoids that second labor cost.
Is Xcel’s Time of Use Rate Good or Bad for Solar?
Mixed, depending on your consumption pattern. Xcel’s RE-TOU rate prices power higher in the on-peak window, which rewards households that export during peak afternoon hours and use their own power off-peak. Households with a battery come out ahead under TOU because the battery shifts evening grid purchases out of the on-peak window. Households with heavy daytime air conditioning and no battery see weaker gains than they would on the flat residential rate.
How we calculate these costs
Headline figures use Colorado’s entry in the EcoGen Solar Cost Index (September 2026 Edition): $3.02 per watt and a 7.00 kW typical system, 4.5% above the $2.89 national figure and tied 37th lowest of 51. The 7.00 kW size is Berkeley Lab’s 2025 median for Colorado single-family installs (6,702 systems). Quote ranges use the $2.69 to $3.41 per watt band competitive Colorado installers quote. Simple payback before incentives divides the typical system’s cost by a year of its output (11,592 kWh) valued at each utility’s own EIA 12-month price (August 2025 to July 2026) with its fixed monthly charge taken out, from EcoGen’s per-utility payback figures of October 19, 2026. It counts no upkeep and no price rises. Incentive and rate data come from the EcoGen Colorado State Profile. Sources include Berkeley Lab’s Tracking the Sun 2024, the NREL and DOE cost benchmark 2024 and SEIA / Wood Mackenzie data, checked against Colorado PUC tariffs. Marketplace aggregators count as marketplace inputs only. Sources accessed May 31, 2026, unless dated otherwise.
