Solar Installers in Fort Collins, CO

Fort Collins is one of Colorado’s most solar-friendly cities — a community-owned utility that actively supports rooftop solar, cash rebates for installation, and a Time-of-Day rate structure that makes solar panels particularly well-suited to reducing peak electricity costs. Fort Collins Utilities (FCU) has built over a decade of infrastructure around residential solar, and more than 3,000 homeowners in the city have already installed systems. But FCU’s net metering program has one feature that every solar buyer needs to understand before sizing their system: any unused annual credits at your 12-month anniversary are forfeited entirely. Getting system sizing right matters more in Fort Collins than almost anywhere in Colorado.

Is Solar Worth It in Fort Collins?

Fort Collins enjoys the same exceptional solar resource as the rest of Colorado’s Front Range — roughly 300 sunny days annually and high-elevation sunlight intensity. A well-designed 5–7kW system typically offsets 80–100% of an average Fort Collins household’s annual electricity consumption.

Fort Collins Utilities has among the lowest residential electricity rates in Colorado, averaging around $0.12/kWh off-peak. Lower rates mean smaller monthly savings and payback periods in the 10–11 year range for cash purchases. EnergySage puts the average Fort Collins payback at about 10.6 years, with 25-year lifetime savings typically over $40,000. Solar installation cost in Fort Collins typically runs $3,500–$4,000/kW before incentives.

Your Utility: Fort Collins Utilities and Time-of-Day Pricing

Fort Collins Utilities is a community-owned, not-for-profit utility operated by the City of Fort Collins with one of the more developed residential solar programs among Colorado municipal utilities.

Time-of-Day (TOD) pricing: All FCU residential customers are on a Time-of-Day rate. On-peak hours are weekdays only — 2–7 PM in summer (May–September) and 5–9 PM in non-summer (October–April). On-peak rates run approximately $0.22/kWh; off-peak approximately $0.07/kWh.

Solar and TOD: Summer peak hours (2–7 PM) align closely with peak solar production. When your panels generate during those afternoon hours, you’re displacing the most expensive electricity you’d otherwise buy — and exporting surplus earns credits at the higher on-peak rate.

Net metering credit rollover — the critical detail: At the end of your 12-month billing anniversary, any remaining unused credits are forfeited to Fort Collins Utilities without compensation. Unlike Xcel Energy (Continuous Rollover) or Colorado Springs Utilities (2 cents/kWh cash-out), Fort Collins provides no payment and no rollover. Work with your installer to right-size the system to your actual annual consumption.

FCU interconnection: Installers must be FCU-approved Participating Solar Contractors to qualify for rebates. Combined timeline from signed contract to Permission to Operate typically runs 8–12 weeks.

FCU Incentives, Battery Storage, and Buying Tips

FCU Solar Rebate: $200/kW of installed DC capacity, up to $1,000 for solar PV. Battery storage qualifies for an additional $150/kWh of usable capacity, up to $3,000, for a combined maximum of $4,000. Paid by check after final inspection. Requires a FCU Participating Solar Contractor and 20-year REC assignment to Fort Collins Utilities.

Epic Loan (on-bill financing): Up to 100% financing with no upfront payment. Terms 3-15 years, starting approximately 5.25% APR, maximum $50,000. Payments appear on your monthly utility bill.

Battery storage and TOD: A battery charged from off-peak electricity or midday solar, then discharged during the 2–7 PM summer peak window, directly reduces the most expensive electricity you would otherwise purchase — making Fort Collins one of Colorado’s stronger markets for solar-plus-storage.

Colorado statewide incentives: Fort Collins homeowners benefit from Colorado’s property tax exemption for solar and the state sales tax exemption on solar equipment.

Frequently Asked Questions

What happens to unused solar credits at the end of the year with Fort Collins Utilities?

Unused net metering credits at your 12-month billing anniversary are forfeited to Fort Collins Utilities without compensation. Unlike Xcel Energy — where you can choose to roll credits forward indefinitely — or Colorado Springs Utilities — which cash out at 2 cents/kWh — Fort Collins provides no payment and no rollover for annual surplus credits. Your system should be sized to match your actual annual electricity consumption as closely as possible. Work with your installer to right-size based on your real 12-month usage history, not on maximizing production.

How does Fort Collins' Time-of-Day pricing affect solar economics?

Fort Collins uses Time-of-Day pricing where on-peak electricity costs significantly more than off-peak. Summer on-peak is 2–7 PM weekdays; non-summer on-peak is 5–9 PM weekdays; all weekends and holidays are off-peak. Solar panels produce the most energy during midday and afternoon hours, which aligns closely with the expensive summer peak window. When your panels export surplus power during on-peak hours, those credits are worth considerably more (approximately $0.22/kWh) than credits earned from off-peak exports (approximately $0.07/kWh). Battery storage that captures midday production and deploys it during peak hours adds further value.

What solar rebates does Fort Collins Utilities offer?

Fort Collins Utilities offers a cash rebate of $200 per kilowatt of installed DC solar capacity, up to $1,000 for solar PV alone. Battery storage qualifies for an additional $150 per kilowatt-hour of usable capacity, up to $3,000 — making the combined maximum $4,000. The rebate is paid after your system passes FCU’s final inspection. You must work with a FCU Participating Solar Contractor and assign your system’s renewable energy credits to Fort Collins Utilities for 20 years. Confirm current funding levels with your installer at time of quote.

What is the Epic Loan and how does it work for solar in Fort Collins?

The Epic Loan is Fort Collins Utilities’ on-bill financing program for solar and battery storage. It covers up to 100% of eligible project costs with no upfront payment, loan terms from 3 to 15 years, and interest rates starting around 5.25% APR, with a maximum loan amount of $50,000. Payments are added to your monthly utility bill. The Epic Loan can be combined with the FCU solar rebate — the rebate applies after installation, reducing your outstanding balance.

Does Fort Collins require a Participating Solar Contractor, and why does it matter?

Yes — to qualify for Fort Collins Utilities’ solar rebate, you must use a FCU-approved Participating Solar Contractor. These installers are vetted by FCU and familiar with the city’s interconnection process, permitting requirements, and rebate application procedures. Using a non-participating contractor means foregoing the rebate entirely. When getting quotes, confirm upfront that each installer is on the FCU Participating Solar Contractor list.
