Two Colorado homes with identical panels can be four to seven years apart on payback, because Xcel and the co-ops credit exports at full retail while Colorado Springs Utilities pays 49% of it. Add Xcel's pending 9.9% rate increase and a time-of-use spread from 7.9¢ to 21.3¢, and your address matters more than your equipment. EcoGen America starts there.

Two Colorado homes with identical panels can be four to seven years apart on payback, because Xcel and the co-ops credit exports at full retail while Colorado Springs Utilities pays 49% of it.
Add Xcel’s pending 9.9% rate increase and a time-of-use spread running from 7.9 to 21.3 cents, and the utility on your bill matters more than the brand on your roof.
On the right grid, Colorado is one of the stronger solar states in the country: 1-to-1 crediting, competitive install prices near $2.98 per watt, and rising rates that make every self-generated kilowatt-hour worth more.
EcoGen America starts with your utility, prices the quote against the crediting you will actually receive, and matches you with installers who work your territory.
Xcel, the co-ops and Colorado Springs Utilities credit exports differently enough to move payback by years. We start with which one bills you.
Built-in checks for crediting assumptions, time-of-use rate spreads, and paybacks quoted off statewide averages your utility does not pay.
We track Xcel rate cases, including the pending 9.9% increase, co-op crediting policies and the Colorado Springs 49% export rate.
Your data is only shared with the licensed Colorado installers you choose.
EcoGen is 100% free for homeowners. We earn a small referral fee from installers only when you choose to proceed with a project through our platform.
Colorado solar quotes love statewide averages. Your utility makes them meaningless. Here is the map that matters.
Your Utility | Export Credit | What It Does to Payback |
|---|---|---|
Xcel Energy | Full retail, 1:1, under state law | The base case, improving with every rate increase; RE-TOU runs 7.9¢ off-peak to 21.3¢ summer peak |
Black Hills Energy | Full retail, 1:1 | Comparable to Xcel territory |
Most rural co-ops | Full retail under co-op net-metering law | Some add rebates: Holy Cross pays $100/kW up to 25 kW from April 2026 |
Colorado Springs Utilities | Avoided cost, ~49% of retail since 2023 | Adds 4 to 7 years to payback on identical systems; self-consumption carries the return |
If you are on the full-retail side, size to your annual usage and let the credit work. If CSU bills you, design like a self-consumption state: daytime load first, exports as an afterthought.
Xcel, Black Hills, a co-op, or Colorado Springs Utilities? The crediting rules on your meter set the strategy before any design.
On Xcel's time-of-use rate, when you consume matters: shifting load into cheap hours and letting solar cover the expensive ones is free money.
Collect competing bids against the $2.98/W competitive benchmark, with the sales-tax exemption already reflected and dealer fees surfaced.
Free 15-minute call. Grid rules, TOU plan, actual payback for your address.
Since late 2025, Xcel residential customers live on a time-of-use rate. Solar and TOU are natural partners if the design respects the clock.
Ask any installer to walk you through how their design works with the RE-TOU rate. If they cannot explain it clearly, keep interviewing.
Colorado Contract Checks
Good market, real variance. These four lines separate the professionals from the door-knockers.
Full-retail crediting or CSU's 49% is a four-to-seven-year difference. The projection must name your utility and use its actual crediting.
Xcel savings depend on the time-of-use schedule, 7.9¢ off-peak against 21.3¢ on-peak. Flat-rate models overstate some designs and understate others.
The 2.9% sales-tax exemption belongs in the sticker automatically, the property-tax exemption is statutory, and co-op rebates like Holy Cross's $100/kW belong in the math where they apply.
Colorado's healthy market still carries fee-heavy loans. The cash price against $2.98/W is the only anchor that holds.
Four lines, any Colorado bid. Front Range installers worth hiring answer them cold.
Vetted for licensing, TOU-aware design, warranties and complaint history.
Good fundamentals, clear exceptions. These cases should wait or redesign.
Green lights: Xcel, Black Hills and co-op households with ordinary-to-high usage, sound roofs and a horizon past the payback. On the right grid, Colorado remains one of the West’s most dependable solar markets. Run yours in our worth-it breakdown.

For most of the state, yes: Xcel, Black Hills and most rural cooperatives credit exports 1:1 at retail under Colorado law.
Colorado Springs Utilities is the exception, crediting at avoided cost, about 49% of retail since 2023, which adds four to seven years to payback on identical systems.
The RE-TOU schedule runs 7.9¢ off-peak to 21.3¢ on summer evenings. Solar production overlaps the climb toward the peak, and load shifting into cheap hours multiplies the benefit.
Ask installers how the design interacts with the schedule; orientation choices genuinely move the return.
The durable ones are exemptions: 2.9% state sales tax waived on solar equipment and a property-tax exemption on added value. Some co-ops add rebates, like Holy Cross Energy’s $100 per kW up to 25 kW from April 2026.
The federal residential credit ended December 31, 2025; leases can still route the commercial credit.
No; it cuts the other way. The pending 9.9% increase, proposed for bills from August 2026, raises what every self-generated kilowatt-hour saves, improving the case for systems bought now and later alike.
Rate inflation is Colorado solar’s quiet tailwind, not a reason to rush or to wait.
Competitive installs run about $2.98 per watt, with typical 6-to-12 kW systems between $17,900 and $35,800 before exemptions per our 2026 Colorado cost data.
Front Range competition is your friend: collect multiple bids and make them meet the benchmark.
