Is solar worth it in Colorado?

What drives solar payback in Colorado

Colorado homeowners pay about 16.3¢/kWh, which is 2.1¢ below the national average. A rooftop here generates roughly 1550 kWh per kW each year — better than the typical US figure. On exports, Colorado offers full retail net metering: Strong sun plus retail net metering make Colorado one of the better-payback states.

A worked example

For a Colorado home with a $143/month power bill (typical household usage at Colorado’s rate):

That nets out to a payback of about 10.8 years — shorter than simply dividing net cost by year-one savings, because power prices climb ~2.5%/yr so your savings grow each year. Assumes 3.00 $/W installed before incentives and a typical 40% self-consumption; your actual cost, roof and usage will differ — adjust the calculator above.

Who supplies your power in Colorado

Colorado's grid is dominated by Xcel Energy (Public Service Company of Colorado), the state's largest investor-owned utility, with Black Hills Energy serving parts of the south. Municipal utilities — among them Colorado Springs Utilities, Fort Collins Utilities and Longmont Power & Communications — run their own programmes, and a large web of rural electric co-operatives (United Power, Poudre Valley REA, Holy Cross Energy and others, many supplied by Tri-State) covers the rest of the state. Investor-owned customers get the strongest and most consistent net-metering terms under state rules. If you're on a muni or a co-op, the headline deal is broadly similar, but the fine print — credit rates, system-size caps and monthly fees — varies, so check with your own provider before you commit.

What you’re paid for what you export

Xcel and Black Hills customers keep one of the cleaner deals left in the country: under Public Utilities Commission rules, each exported unit knocks a full-price unit off your bill, and surplus credits roll forward month to month. Whatever remains at the annual true-up gets settled at the lower avoided-cost (wholesale) rate, so size the array to your own yearly usage rather than deliberately overbuilding for a payout. In practice the grid soaks up your surplus and hands it back at no loss — what you push out on sunny afternoons cancels what you pull back at night, the opposite of California's net-billing regime. Municipal and co-op customers usually get net metering too, but caps and credit terms differ, so confirm the details before sizing.

Colorado incentives & taxes in 2026

Solid rather than spectacular is the fair summary. Colorado has no SREC market and no cash rebate on the New Jersey scale, but it exempts solar equipment from sales tax and grants a 100% property-tax exemption on the added home value, so your assessment doesn't climb because you went solar. The most useful cash support is utility-run: Xcel Energy's Solar*Rewards programme pays residential customers a modest production-based incentive, and several munis and co-ops — Holy Cross Energy and Colorado Springs Utilities among them — offer their own rebates that come and go with budgets.

The 30% federal credit ended on 31 December 2025 and can now only reach a homeowner indirectly through a lease or PPA. Check the current state and utility programs on DSIRE’s Colorado list, then type any incentive into the calculator above to see how it shortens your payback.

What solar costs in Colorado

Front Range competition keeps Colorado pricing keen: expect about $2.70–$3.10 per watt on a residential job, or $19,000–$24,000 for a typical 7–8 kW system before incentives, with mountain and rural work running higher on labour and logistics. The sticker price is what most owners now actually pay, so gather three or four quotes and compare the equipment on offer, not just the headline number.

The honest verdict for Colorado

Colorado still sits among the better-payback states. Strong sun — about 1,550 kWh per kW a year — combined with retail-rate net metering means the panels offset expensive grid power efficiently, and the sales- and property-tax exemptions quietly help the numbers. Without production income or a large rebate, though, payback at around 16 cents/kWh typically comes in at 9–12 years: behind SuSI-boosted New Jersey, comfortably ahead of the net-billing states. If you own the system outright and plan to stay in the home, it still adds up.

Your home electricity rate also sets what it costs to charge an EV and whether a heat pump beats a gas furnace. See the Colorado EV charging cost and the Colorado heat pump vs gas comparison.
