A typical 7 kW home solar system in Colorado runs about $18,000 to $24,000 before incentives, or roughly $3.41 per watt. At Denver production and Colorado’s power rate, that system offsets close to $1,800 a year, so a cash payback of about 10 to 13 years is realistic in 2026.
If you are pricing rooftop solar in Colorado, this page walks through what a system actually costs here, how the payback math works using real Denver production and Colorado’s electric rate, and which incentives still apply now that the federal homeowner credit has ended. Colorado gets a lot of high-altitude sun, and its power rates sit near the national average, so the cost-versus-savings picture is solid without being extreme. We keep the numbers honest and dated so you can sanity-check any installer quote against them.
What solar panels cost in Colorado in 2026
Solar is priced per watt, then scaled to the system size your roof and usage call for. In Colorado the 2026 average is about $3.41 per watt before any incentives, with real quotes scattering from roughly $2.75 to $3.52 per watt depending on the installer, the equipment, and the roof (SolarReviews Colorado). Most homes land on a 6 kW to 9 kW system, and a 7 kW system is a common middle.
| System size | Rough Colorado cost before incentives (at ~$2.75 to $3.52 per watt) |
|---|---|
| 5 kW | About $13,750 to $17,600 |
| 7 kW | About $19,250 to $24,600 |
| 9 kW | About $24,750 to $31,700 |
Two things move your final number more than anything else: the equipment tier you pick and whether you add battery storage. A battery is a separate line item that raises the up-front cost, so price the panels-only system first, then decide on storage. For a broader look at what drives value, see the financial case for whether solar panels are worth it and how solar lowers your electricity bill.
The Colorado payback math, using real numbers
Payback is just the up-front cost divided by what the system saves you each year. The savings side depends on two local facts: how much power your roof makes, and what a kWh costs where you live.
- Production: A 7 kW system in Denver (ZIP 80202) is modeled to make about 11,165 kWh a year, thanks to Colorado’s strong high-altitude sun of about 5.66 kWh per square meter per day (NREL PVWatts).
- Rate: Colorado residential power runs about 16.16 cents per kWh (EIA Electric Power Monthly, period May 2026), close to the national average.
Put those together and the bill offset is straightforward. According to MySolarFY’s analysis (August 2026), a typical 7 kW system in Denver produces about 11,165 kWh a year, which at Colorado’s 16.16 cents per kWh residential rate offsets roughly $1,800 on the yearly power bill. Divide the system cost by that yearly saving and you get the payback window.
| Cost scenario (7 kW, cash) | Up-front cost | Yearly bill offset | Rough cash payback |
|---|---|---|---|
| Lower end (~$2.75 per watt) | About $19,250 | About $1,800 | About 11 years |
| Colorado average (~$3.41 per watt) | About $23,870 | About $1,800 | About 13 years |
These are illustrative estimates, not a quote. They assume you offset production at the retail rate through Colorado net metering, no financing costs, and Colorado’s Xcel Energy (Public Service Company of Colorado) or a similar utility crediting your exports. A loan spreads the cost but adds interest, and rising utility rates would shorten payback. Get your own numbers from a licensed installer before you commit.
Colorado incentives that still apply (and the one that ended)
The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, under the One Big Beautiful Bill Act, so a Colorado homeowner who buys solar with cash or a loan in 2026 cannot claim it (IRS OBBB FAQ). That is the single biggest change to the payback math this year, and it is why the windows above are longer than they would have been in 2025. For the full timeline, see what the federal solar tax credit change means in 2026.
What Colorado still offers:
- A state sales and use tax exemption on qualifying solar equipment, so you do not pay Colorado sales tax on the components (SEIA solar tax exemptions).
- A property tax exemption for the added home value of a residential renewable energy system, so going solar does not raise your property tax assessment (DSIRE Colorado property tax exemption).
- Net metering. Colorado requires investor-owned utilities like Xcel Energy to offer net metering, crediting the excess power your system exports, with systems sized up to 120% of your average annual use. For Xcel customers specifically, see Xcel Energy net-metering rules and rates in Colorado, and for the mechanics, see how net metering credits your solar exports, and for the incentives that still apply, see the solar incentives that still apply in 2026.
Colorado does not run a statewide SREC market, so unlike some Northeast states there is no separate certificate income to bank on here. The value comes from the bill offset, the tax exemptions, and any utility program you qualify for.
How to pay for solar in Colorado
There are three common ways to pay, and they change who captures the savings:
- Cash. You pay the full cost up front and keep every dollar of the bill offset and the tax exemptions. This is the fastest payback and the lowest lifetime cost.
- Solar loan. You spread the cost over a loan term and still own the system, so you keep the net-metering value and the exemptions, but interest raises the total you pay.
- Lease or PPA. A company owns the panels and you pay a monthly amount or a per-kWh rate. Some homeowners may qualify for $0-up-front lease or PPA options where available, but on those contracts the company that owns the system typically keeps the net-metering credits, and total payments over 20 to 25 years may exceed a cash purchase.
Ownership is the theme: buying the system with cash or a loan keeps the Colorado net-metering value and the tax exemptions in your name. To pressure-test any offer, use the right questions to ask a solar installer.

How to choose a solar installer in Colorado
Colorado is a deep solar market, so you have many licensed installers to compare. Rather than chasing a “best” list, screen any installer against objective criteria:
- NABCEP certification, the industry’s professional standard for PV installers.
- Proper Colorado licensing and any required local electrical and building permits.
- A clear workmanship and equipment warranty in writing.
- Real experience with your utility’s interconnection and Colorado net metering, so the paperwork and permission to operate go smoothly.
- A written production estimate and a transparent quote that is honest about payback now that the federal credit has ended.

Frequently asked questions
How much do solar panels cost in Colorado in 2026? A typical home system runs about $3.41 per watt before incentives, with real quotes from roughly $2.75 to $3.52 per watt. That puts a common 7 kW system around $19,250 to $24,600 before incentives, and a 5 kW system closer to $13,750 to $17,600. Battery storage is a separate cost on top. Get a written quote for your roof, since the equipment tier and your usage move the final number.
What is the payback period for solar in Colorado? For a cash purchase in 2026, a rough payback is about 10 to 13 years. That comes from a typical 7 kW system in Denver producing about 11,165 kWh a year (NREL PVWatts) and offsetting power at Colorado’s residential rate of about 16.16 cents per kWh (EIA), which saves close to $1,800 a year against a system cost of roughly $19,250 to $23,870. A loan adds interest, and rising utility rates would shorten the window.
Are solar panels worth it in Colorado? For many owner-occupied homes, yes, because Colorado’s strong sun and near-average rates give a reasonable payback and the system keeps saving for years after it pays for itself. The federal homeowner credit ending in 2025 lengthened payback, so the case is stronger for cash or loan buyers who keep the net-metering value and tax exemptions than for lease or PPA customers who do not.
Does Colorado have a solar tax credit? Colorado does not have a statewide residential solar income-tax credit, but it does exempt qualifying solar equipment from state sales and use tax and exempts the added home value of a solar system from property tax. The 30% federal Residential Clean Energy Credit (Section 25D) ended for expenditures made after December 31, 2025, so cash and loan buyers in 2026 cannot claim it.
Is there net metering in Colorado? Yes. Colorado requires investor-owned utilities like Xcel Energy to offer net metering, which credits the excess power your system sends to the grid, with residential systems sized up to about 120% of your average annual usage. The exact crediting details depend on your utility, so confirm the current terms with your provider before you size a system.

MySolarFY is a free service that matches homeowners with licensed solar installers. We are not an installer, financing company, or government program. “No up-front cost” refers to qualifying lease or PPA financing, where eligible homeowners may have no out-of-pocket cost at installation. Lease and PPA terms typically run 20 to 25 years, may include an annual price escalator, and total payments may exceed the cost of a cash purchase; on a lease or PPA the net-metering credits often go to the company that owns the system, not the homeowner. Homeowners do not get the federal residential credit that ended after December 31, 2025. Solar panels are not free and monthly payments apply.
