Colorado is a patchwork, and that is the thing to understand before you read a single quote. What you are paid for exported power, whether a rebate exists, and whether a battery incentive applies all depend on which utility serves your address rather than on any statewide rule. Xcel territory works one way, a municipal utility works another, and a rural co-operative works a third.
The state layer is thin and mostly consists of exemptions: solar equipment is exempt from sales tax, and the added home value is exempt from property tax assessment. Real money can sit on top of that through Xcel’s Solar*Rewards, particularly for income-qualified households, but it is a program with its own eligibility and capacity, not an entitlement. With the 30% federal residential credit at $0 for systems completed after December 31, 2025, the local layer is now carrying weight it did not have to carry before.
Four vetted installers reach Colorado, three of them concentrated on the Front Range. Because the incentive picture changes with your utility rather than your state, the first question is not who is cheapest. It is which company can name your utility and tell you what that specific territory pays, including whether Solar*Rewards is open to you.
Our Top 4 Solar Companies in Colorado
Namaste Solar
Twenty-one years on the Front Range and the longest Colorado-specific record here. Long tenure in one territory usually means fluency with the utilities that actually serve it. Ask them which utility covers your address and what its export terms are, and expect a precise answer rather than a statewide generality.
Palmetto
The only company here publishing its warranty terms in full: 25 years on panels and inverters with a separate 10-year workmanship commitment. That is a clearer written position than most. It operates across fifteen states, so ask how often a crew is in your part of Colorado and who returns for a callback.
Photon Brothers
A Front Range operator that also works in California, which is a useful combination because California has spent years adapting to export credits worth far less than retail. That experience is relevant in any Colorado territory where export value is thin. Ask what they assume your exports are worth and where the figure comes from.
Big Dog Solar
Serves Colorado as part of wider Mountain West coverage and publishes a 10-year workmanship warranty that explicitly names roof penetrations. Roof cover stated in writing is worth asking about anywhere hail is a factor, and Colorado has more of it than most states.
Colorado Solar Companies Compared
Company | Years Operating | Colorado Coverage | Published Warranty | Where It Fits |
|---|---|---|---|---|
Namaste Solar | 21 | Front Range | Not published | Longest Colorado-specific record |
Palmetto | 15 | Statewide, 15-state firm | 25-yr panel and inverter, 10-yr workmanship | The clearest written warranty position |
Photon Brothers | Not published | Front Range | Not published | Also works under California export rules |
Big Dog Solar | 18 | Part of Mountain West coverage | 10-yr workmanship + roof | Roof penetrations named explicitly |
Three of the four concentrate on the Front Range, where most of the population is. If you are on the Western Slope or in a rural co-operative territory, ask directly how often crews reach your county before comparing anything else.

Colorado Solar FAQs
Does Colorado have statewide net metering?
Not in a single uniform form. What you are credited for exported power depends on whether you are served by Xcel, a municipal utility or a rural co-operative, so the answer is set by your address rather than by the state.
What is Solar*Rewards and can I get it?
It is an Xcel program that can pay meaningfully, especially for income-qualified customers. It is not automatic: it has eligibility rules and limited capacity, so confirm both that you qualify and that it is currently accepting before treating it as part of your economics.
Will solar increase my property taxes in Colorado?
No. Colorado exempts the added value of a residential solar system from property tax assessment, and solar equipment is also exempt from sales tax.
Is hail a real risk to solar panels here?
It is a genuine design consideration in Colorado rather than a theoretical one. Ask about the panels’ impact rating, how the array is mounted, and how a hail claim would be handled between your insurer and the installer’s workmanship warranty.
Are these companies based in Colorado?
Namaste Solar and Photon Brothers are Front Range operators. Palmetto and Big Dog Solar serve Colorado as part of multi-state coverage, which we would rather state plainly than let a statewide claim imply a local crew.
