Aurora’s solar fundamentals are excellent. Like Denver — which it borders — Aurora sits at high elevation with thin atmosphere, intense sunlight, and around 300 sunny days annually. A properly sized 6–7kW system offsets the majority of most Aurora households’ annual electricity use.
The economics depend partly on which utility serves your home. Xcel and CORE rates are similar (~14–15¢/kWh), keeping payback periods in roughly the 7–11 year range for cash purchases. EnergySage and Palmetto both estimate the Aurora metro payback around 7–8 years for average systems. Over 25 years, savings typically run $40,000–$57,000. The strongest case for solar here is locking in decades of free production against utility rates that have been rising steadily — Xcel’s rates are up roughly 15% since 2021, and CORE approved a 5% increase in September 2025 followed by an average 6.7% increase effective January 2026. Households with electric vehicles, heat pumps, or higher-than-average electricity use see the best payback.
First step: confirm your utility.** The City of Aurora is served by both Xcel Energy (the majority of the city) and CORE Electric Cooperative (southeastern Aurora neighborhoods, particularly toward Centennial and Arapahoe County). Your utility is identified on your monthly electric bill. If you’re unsure, your zip code is a reliable starting point — installers familiar with the Aurora market will know the service territory boundaries — but the definitive answer is your bill.
**If you’re an Xcel Energy customer:**
Your solar experience mirrors what Denver homeowners get. Xcel offers full retail-rate, 1:1 net metering. Excess monthly credits accumulate in your Solar Bank. At setup, you choose between Continuous Rollover (credits accumulate indefinitely at full retail value — the better choice for most homeowners) or annual cash-out at the Average Hourly Incremental Cost rate, which is well below retail. Xcel allows systems sized up to 120% of your prior 12-month usage. The Xcel Solar*Rewards IQ/DIC program — up to $1/watt rebate for homes in mapped Disproportionately Impacted Community areas — applies if your address qualifies. The Renewable Battery Connect program ($500/kW, roughly $3,500 for a Powerwall) is also available. Xcel’s interconnection timeline for standard residential systems typically runs 3–6 weeks after city permit approval; combined total from contract to Permission to Operate is generally 8–14 weeks.
**If you’re a CORE Electric Cooperative customer:**
CORE (formerly Intermountain Rural Electric Association, rebranded in 2021) is a member-owned, not-for-profit electric cooperative. CORE’s net metering also credits excess solar at the full retail rate month to month — but the annual true-up works differently than Xcel. CORE automatically cashes out any remaining year-end excess in April at its **avoided cost rate** — approximately $0.045/kWh as of May 2025. Unlike Xcel, CORE does not offer a Continuous Rollover choice; the April cash-out at avoided cost is automatic. This means oversizing your CORE system is even less financially beneficial than in Xcel territory. Size your system to match your consumption as closely as possible to maximize the value of full-retail monthly credits.
CORE also has a three-part rate structure that Xcel residential customers don’t have: a $20/month basic service charge, an energy charge (~$0.1155/kWh as of January 2026), and a **demand charge** ($5.47/kW based on your highest 60-minute consumption during on-peak hours of 4–8 PM). The demand charge is worth understanding for battery storage decisions — a battery that reduces your peak 4–8 PM grid draw can reduce your demand charge directly, adding value beyond simple export credits.
CORE allows systems sized up to 200% of your prior 12-month usage — a larger ceiling than Xcel — though the automatic low-rate cash-out at true-up means production beyond your annual usage has limited financial return. CORE’s Xcel-specific incentive programs (IQ/DIC rebate, Battery Connect) do not apply; check CORE’s current programs at core.coop for what’s available.
Colorado statewide incentives:** Aurora homeowners benefit from Colorado’s property tax exemption for solar (installed value doesn’t increase your assessed property taxes) and the state sales tax exemption on solar equipment. Confirm with your installer whether Arapahoe County or Aurora municipal taxes also apply to your installation.
**Xcel IQ/DIC rebate (Xcel customers only):** Portions of Aurora’s older neighborhoods and lower-income zip codes appear on the Colorado EnviroScreen map as Disproportionately Impacted Communities. Xcel customers in those areas qualify for the $1/watt installation rebate (up to $7,000 for 7kW). As with all Xcel DIC program funding, it’s first-come, first-served annually. Confirm your address on Xcel’s EnviroScreen map before installation.
**Battery storage considerations:** In Xcel territory, full retail-rate net metering means batteries are financially optional — they add resilience and backup value but don’t dramatically change the solar ROI math. In CORE territory, the demand charge structure changes the calculation: a battery that consistently reduces your peak 4–8 PM grid draw can reduce the demand charge on your monthly bill, adding financial value that goes beyond what pure solar provides. If you’re on CORE and considering battery storage, ask your installer to model demand charge reduction explicitly.
**Hail:** Aurora sits in the same Front Range hail corridor as Denver and Colorado Springs. Class 4 impact-resistant panels are a sound investment. Ask any installer you evaluate whether proposed panels carry a Class 4 rating.
