The residential federal solar tax credit expired on December 31, 2025. But going solar in Colorado still makes strong financial sense thanks to dramatically lower panel prices, rising utility rates, state-level incentives, and the long-term value of energy independence.

For years, the federal Investment Tax Credit was one of the biggest financial incentives for going solar. At its peak, homeowners could claim 30 percent of their total solar installation cost as a dollar-for-dollar credit on their federal income taxes. It was a powerful motivator, and it helped millions of Americans make the switch to solar energy.

As of December 31, 2025, the residential solar ITC has expired. If you did not have your system installed and operational before that deadline, the federal credit is no longer available for residential installations.

So here is the question we are hearing from homeowners across the Front Range every day: is solar still worth it without the tax credit?

The short answer is yes, and in this article we will show you exactly why.

What Happened to the Federal Solar Tax Credit

The residential clean energy credit, established under the Inflation Reduction Act, provided a 30 percent tax credit for solar energy systems installed on primary residences. The credit applied to the total cost of the system, including panels, inverters, batteries, installation labor, and related electrical work.

Under the original IRA timeline, the 30 percent credit was scheduled to remain available through 2032 before stepping down gradually. However, legislative changes accelerated the expiration for residential systems, and the credit was not renewed beyond December 31, 2025.

It is worth noting that the commercial solar Investment Tax Credit still exists for businesses, nonprofits, and certain other entities. If you are a business owner considering solar, the federal incentive landscape remains favorable, and we encourage you to explore commercial solar options.

Solar Panel Prices Have Dropped Dramatically

Here is what many people overlook in the tax credit discussion: the cost of solar panels has fallen so significantly that today's out-of-pocket cost without the credit can be comparable to what homeowners paid five or six years ago with the credit.

In 2019, a typical residential solar installation in Colorado cost around $3.50 to $4.00 per watt before the tax credit. With the 30 percent credit, the effective cost was roughly $2.45 to $2.80 per watt. Today, quality solar installations using premium equipment range from $2.50 to $3.25 per watt, and many systems come in near the lower end of that range.

The global solar manufacturing market has expanded enormously, driving panel prices to historic lows. Inverter technology has become more efficient and more affordable. Installation practices have become streamlined. The result is that solar economics work even without federal subsidies.

For a typical 8 kW residential system in Colorado, you are looking at a total cost in the range of $20,000 to $26,000. Without the federal credit, yes, you pay the full amount. But the full amount today is lower than the after-credit amount was just a few years ago.

Utility Rates Keep Rising

The other side of the solar equation is not just what you pay for the system but what you save on electricity for the next 25 to 30 years. And on that side, the math is getting more favorable every year.

Xcel Energy, the dominant utility provider along Colorado's Front Range, has implemented significant rate increases over the past several years. The average residential electricity rate in the Xcel service territory has risen by approximately 30 to 40 percent over the last five years, and additional increases are expected as the utility invests in grid infrastructure, wildfire mitigation, and its own clean energy transition.

Every rate increase makes solar more valuable because the electricity your panels produce is electricity you do not have to buy at ever-higher prices. A solar system installed today locks in a significant portion of your energy costs for decades, while utility customers without solar will continue to absorb rate increases year after year.

Colorado State and Local Incentives Still Exist

While the federal credit has expired for residential systems, Colorado and local jurisdictions continue to offer incentives that reduce the cost of going solar:

• Colorado sales tax exemption: Solar energy equipment is exempt from state sales tax, saving homeowners roughly 3 to 4 percent on their total system cost.
• Property tax exemption: The added home value from a solar installation is exempt from property tax reassessment in Colorado. Your home value goes up, but your property taxes do not.
• Net metering: Xcel Energy's net metering program allows you to earn credits for excess solar production that you send back to the grid, applied to future electric bills.
• Renewable energy credits (RECs): Some utility programs offer payments or credits for the renewable energy your system produces.
• Local utility rebates: Depending on your specific utility provider, additional rebates may be available. Municipal utilities like Longmont Power & Communications and Fort Collins Utilities have historically offered solar rebates and incentives.

Taken together, these state and local incentives still provide meaningful financial benefits that improve your solar return on investment. For a comprehensive breakdown, see our complete guide to solar in Colorado.

The Real Math: Payback Period Without the Federal Credit

Let us walk through a realistic example for a Colorado homeowner.

System details:

• System size: 8.4 kW
• Total installed cost: $23,000
• Federal tax credit: $0 (expired)
• Effective cost after state sales tax exemption: approximately $22,100
• Estimated annual production: 12,600 kWh
• Current average Xcel rate: approximately $0.16 per kWh
• Year one savings: approximately $2,000
• Annual utility rate increase assumption: 4 percent

With these assumptions, the payback period lands at approximately 9 to 11 years. After payback, the system produces essentially free electricity for another 15 to 20 years of its warranted life. Over 25 years, cumulative savings often exceed $60,000 to $80,000 depending on how aggressively utility rates rise.

Is the payback period longer without the federal credit? Yes, by roughly two to three years compared to when the 30 percent credit was available. But a 9 to 11 year payback on a 25-plus year asset is still an excellent investment. You would be hard-pressed to find any home improvement project with a comparable return.

Energy Independence Has Real Value

Financial returns tell only part of the story. For many Colorado homeowners, the value of energy independence cannot be captured in a payback calculation.

When you generate your own electricity, you are no longer fully subject to utility rate decisions made by regulators and corporate boards. You are insulated from energy market volatility. If you pair solar with battery storage like a Tesla Powerwall or Enphase battery system, you also gain protection against power outages, which are becoming more frequent along the Front Range due to severe weather events.

There is also the environmental dimension. Every kilowatt-hour your solar panels produce is a kilowatt-hour that does not need to come from fossil fuels. For homeowners who care about reducing their carbon footprint and contributing to Colorado's clean energy goals, the value extends well beyond the electric bill.

A Note for Business Owners: The Commercial ITC Still Exists

If you own a business, the federal landscape is different. The commercial Investment Tax Credit remains available and continues to offer significant tax benefits for businesses that install solar energy systems. Combined with MACRS depreciation, the effective cost reduction for commercial solar can be substantial.

Should You Wait for a New Federal Incentive?

We hear this question often: should I wait and see if Congress passes a new residential solar tax credit?

It is a reasonable question, but consider the following. First, there is no current legislation pending that would reinstate the residential solar credit, and there is no guarantee one will be introduced or passed. Second, while you wait, you continue paying full price for electricity from the utility, and those rates continue to rise. Third, solar equipment prices are already at historic lows and may not drop significantly further since manufacturing costs have largely stabilized.

Every month you wait is a month of full-price electricity that you could have been generating yourself. A system installed today starts saving you money today, and those savings compound over time as utility rates increase.

The Bottom Line

The federal solar tax credit was a great incentive while it lasted. Its expiration is unfortunate for homeowners who did not get the chance to take advantage of it. But the fundamentals of solar economics in Colorado remain strong:

• Solar panel prices are at historic lows
• Utility electricity rates continue to climb
• Colorado state incentives remain in place
• 300-plus days of sunshine make Colorado ideal for solar
• Home value increases from solar are tax-exempt
• Payback periods remain attractive at 9 to 11 years

Going solar in 2026 without the federal credit is still one of the smartest financial and environmental decisions a Colorado homeowner can make. The credit made a good investment great. Without it, solar is still a good investment.
