This guide explains solar panel cost Colorado homeowners may see, using the state average installed price of $2.63 per watt (EnergySage Colorado cost data (average, before incentives), October 2026) before incentives. At that price a 7 kW system costs about $18,410. Homeowners who buy a system in 2026 get no federal tax credit, so that price is close to what you actually pay, though Colorado exempts solar equipment from state sales tax and home systems from property tax.
Solar panel cost Colorado: compare typical system sizes
Installers price systems by the watt, so the size you need drives the total. At the average price above:
| System size | Estimated installed cost |
|---|---|
| 5 kW | about $13,150 |
| 7 kW | about $18,410 |
| 9 kW | about $23,670 |
| 11 kW | about $28,930 |
EnergySage reports a range of $25,377 to $34,333 for a 11.36 kW system in Colorado, which is about $2.23 to $3.02 per watt. Real quotes vary with your roof, equipment, permitting and the company. Compare quotes in dollars per watt (total price ÷ system watts) so different system sizes line up.
No federal tax credit for buyers in 2026
The 30% federal credit for homeowners (Section 25D) ended for systems placed in service after December 31, 2025 (Solar.com). If you buy with cash or a loan, do not subtract 30% from any quote. Companies that own a system on your roof (a lease) can still claim a business credit; see our lease vs. buy guide.
Colorado’s electricity rate
The average Colorado residential rate was 17.17¢ per kWh (U.S. EIA, Electric Power Monthly (residential average price), updated automatically, August 2026). Each kWh your panels make saves you that much only when it replaces power you would have bought, so payback depends heavily on your own bill. Use the rate printed on your bill in the calculator if you can.
Net metering in Colorado
Colorado Revised Statutes Section 40-2-124 requires investor-owned utilities such as Xcel Energy to offer net metering. A home system can be sized up to 200% of your expected yearly use. Extra power you send to the grid in a month is credited against your use the next month, and credits carry forward until you end service. If you produce more than you use over a calendar year, you can choose in writing to be paid for the extra at the utility’s average hourly incremental cost of electricity supply for that year. Leftover credits are not paid out when you close your account, but you can donate them to a qualified low-income assistance program.
The statute sets separate rules for city utilities with 5,000 or more customers (residential systems up to 10 kW, with excess kWh carried forward), and electric cooperatives are not covered by the same section. If a co-op or city utility serves you, ask it in writing how it credits exported power before you sign a solar contract.
Colorado sales tax exemption
Under Section 39-26-724, components used to produce electricity from a renewable source, such as solar panels, inverters, racking and wiring, are exempt from Colorado state sales and use tax and from some special district taxes, including the RTD and Scientific and Cultural Facilities District taxes. Most city and county sales taxes still apply unless your city or county has adopted the exemption, and home-rule cities set their own rules. Installation labor is not exempt. Check how your quote handles tax.
Colorado property tax exemption
Colorado’s Division of Property Taxation says an independently owned solar system on residential property is exempt from property tax if it produces electricity mainly for that home and has a capacity of no more than 100 kW AC. Ask your county assessor if you have questions about your home.
We have not verified any statewide Colorado rebate or tax credit for home solar as of the review date above. Some utilities and cities run their own programs; ask yours.
HOAs and solar in Colorado
Under Section 38-30-168, a covenant or deed restriction that effectively prohibits or restricts installing or using a solar energy device is void. An association can still set reasonable rules on size, placement and appearance, but those rules cannot raise the cost or cut the system’s performance by more than 10%, and the association must decide within 60 days or the application is deemed approved. The law does not give you the right to install on common elements.
Hail, snow, roofs and insurance
- Ask each installer what hail, snow and wind ratings the panels and racking are installed to, and confirm the job will be permitted and inspected.
- If your roof is near the end of its life, price a re-roof first. Removing and reinstalling panels later adds cost.
- Call your homeowners insurer before you sign to ask how solar affects your coverage and premium.
Questions to ask every installer
- What is the price per watt, and what exactly is included (permits, monitoring, roof work, electrical upgrades)?
- Which panels and inverters, and what are the product and workmanship warranties?
- How did you estimate my production, and how did you account for shade and snow?
- Which utility’s net metering terms does your savings estimate assume, and does it include any monthly meter charges?
- Which Colorado and local licenses and permits apply, and who does the installation: your crew or a subcontractor?

Colorado solar cost questions
How much do solar panels cost in Colorado?
The average installed price of home solar in Colorado is $2.63 per watt (EnergySage Colorado cost data (average, before incentives), October 2026), before any incentives. Real quotes vary with your roof, equipment, permitting and the installer. The system-size table above shows typical totals.
Is solar worth it in Colorado?
It depends on your own bill and rate. Colorado’s average residential rate was 17.17¢ per kWh (U.S. EIA, Electric Power Monthly (residential average price), updated automatically, August 2026), and investor-owned utilities must offer net metering. Enter the rate printed on your own bill in our calculator to see a closer estimate for your home.
Is there still a federal tax credit for solar in Colorado?
No. The 30% federal credit for homeowners under Section 25D ended for systems placed in service after December 31, 2025, so a Colorado homeowner buying in 2026 should not subtract 30% from any quote. Companies that own a system on your roof can still claim a business credit.
Does Colorado have a property tax exemption for solar?
Yes. The Division of Property Taxation says independently owned home solar systems of 100 kW AC or less that mainly power the home are exempt.
Can my HOA ban solar panels in Colorado?
No. Section 38-30-168 voids restrictions that effectively prohibit or restrict solar devices. An association can set reasonable rules on size, placement and appearance within the limits in the statute.
