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.

Colorado’s net-metering law gives Xcel, Black Hills and most rural cooperative customers a full retail credit for every exported kilowatt-hour. Colorado Springs Utilities went its own way in 2023, crediting exports at avoided cost, about 49% of retail, and that single difference stretches payback by four to seven years on identical systems.
The grid is also getting pricier: Xcel’s residential time-of-use rate runs from 7.9¢ off-peak to 21.3¢ on summer evenings, and the utility has a 9.9% increase pending that would raise bills from August 2026. Every rate bump raises what a system you already own saves.
The trimmings are real but modest: a 2.9% state sales-tax exemption, a property-tax exemption on added value, and co-op extras like Holy Cross’s $100-per-kW rebate. The federal residential credit ended December 31, 2025.
EcoGen America models the utility on your bill, prices quotes against the $2.98/W competitive benchmark, and matches you with Front Range installers who design for time-of-use reality.
Every installer we list designs to your utility's actual crediting, full retail or Colorado Springs' 49%, not a statewide assumption.
Built-in checks for CSU quotes modeled at full retail, TOU-blind savings estimates, and dealer fees inside financed totals.
Xcel's pending 9.9% increase and TOU schedule are in our models before they hit your bill.
Your information goes only to the installers you choose to hear from. Nothing is resold.
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.
This fee comes from the installer’s marketing budget and does not increase your system price. In fact, our pre-negotiated rates often save you money compared to going direct.
Colorado solar quotes love statewide averages. Your utility makes them meaningless. Here is the honest map.
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.

Free 15-minute call. Grid rules, TOU plan, honest 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 how their design interacts with RE-TOU. Blank looks are disqualifying in 2026 Colorado.

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 7.9-to-21.3¢ schedule. 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 honest anchor.
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, honest 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.
