Colorado Solar Panels

For a qualifying customer-sited energy storage system installed in a Colorado residential building, the credit is 10% of the qualifying purchase price, with no dollar cap stated in the program materials. Solar panels are not required, and a renter may qualify if they purchase and install the system with the property owner’s approval. HB26-1289 extended the credit through December 31, 2029.

The qualifying price includes eligible tangible personal property, sales tax charged, and freight, but excludes assembly, installation and other construction services, and permit fees. An owner who claims the credit on a Colorado return receives a nonrefundable credit and cannot carry unused credit forward. Alternatively, the buyer may assign it to the seller, who must pass the full value to the buyer as a purchase-price discount; check current Colorado Department of Revenue forms and documentation rules before purchase.

Colorado exempts qualifying residential energy storage systems from the state’s 2.9% sales and use tax for calendar years 2023 through 2032. The exemption is generally applied by the seller at the time of purchase, reducing the eligible battery purchase cost by the state tax that otherwise would have been charged.

The exemption does not automatically eliminate city, county, or other local sales taxes. Local adoption and home-rule tax treatment may differ, so ask the seller to identify the taxes being collected for the delivery or installation address and confirm local rules before signing.

Colorado’s exemption covers qualifying renewable-energy components used to produce alternating-current electricity. Listed solar-related equipment includes modules, trackers, inverters, racks or support structures, wiring, and related components. The exemption can reduce the taxable equipment cost of a qualifying solar installation; it is not a cash rebate.

The exemption’s application differs among state-administered taxes and local jurisdictions. It generally extends to certain state-administered special-district taxes but not most state-administered city and county taxes, and local or home-rule treatment may differ. Confirm which equipment and tax jurisdictions qualify with the seller or the Colorado Department of Revenue.

Colorado law provides a property-tax exemption for an independently owned residential solar-electric generation facility that is not used to produce income. This can prevent qualifying residential solar equipment from increasing the property-tax assessment, but it is not a cash payment or a reduction in the system’s purchase price.

The exemption depends on ownership and use of the facility. The statute also provides that qualifying rebates, offsets, credits, and reimbursements are not treated as income for this exemption. Homeowners should confirm how the local assessor applies the statute to their equipment and ownership arrangement.

Colorado law requires qualifying utilities to offer net-metering service under applicable statutes and rules. Customers with eligible solar generation may receive bill credits for electricity sent to the grid, but there is no single statewide 2026 export-credit rate. The value and treatment of surplus generation depend on the utility and the customer’s tariff.

Utilities can differ in whether credits are banked, time-varying, or settled at an avoided-cost or other filed rate, and fixed or demand charges may still apply. Before installing solar, review the current utility rate schedule, interconnection requirements, system-size limits, and the rules for annual surplus-credit settlement.

Community solar lets a customer subscribe to a share of an off-site solar project and receive credits on their utility bill, without installing rooftop panels. Colorado’s inclusive community-solar rules reserve at least 51% of capacity in qualifying new facilities allocated capacity from 2026 for income-qualified subscribers and require a minimum subscription discount of 25% of bill-credit value in covered cases; higher minimum discounts can apply to specified federally supported projects.

HB26-1225 provides for fixed bill credits for eligible income-qualified community-solar subscribers beginning October 1, 2026, with annual adjustments. Availability, subscription terms, and the actual bill benefit depend on the project and utility. Review the state requirements and the provider’s contract before enrolling.

Xcel’s Renewable Battery Connect offers a standard upfront incentive of $250 per kW AC of maximum continuous discharge power, capped at $5,000 per application. The listed higher tiers are $1,000 per kW AC for income-qualified customers and $500 per kW AC for customers in disproportionately impacted communities; each higher-tier incentive is capped at 75% of eligible equipment-only cost. Participating customer types may also receive $100 per year for five years for taking part in control events.

The battery must meet Xcel’s equipment and enrollment requirements and be available for utility management during grid-demand events; eligible equipment lists include specified Tesla Powerwall and Enphase models. The 2026 program reopened May 21, and Xcel’s posted budget information was last updated September 1, 2026. Funding can change, so confirm eligibility, remaining funds, and event obligations with Xcel or an authorized installer before committing.

Xcel’s posted income-qualified on-site solar guidance lists an incentive of $1 per watt of installed solar, up to 7 kW. The published eligibility guidance includes households at or below 200% of the federal poverty guideline or 80% of area median income, as well as households qualifying through specified assistance programs. Actual participation depends on the current program offer, application approval, and available funding.

Xcel’s 2026–2027 renewable plan includes targeted income-qualified and disproportionately impacted community solar offerings. A residential incentive-calculation notice posted in September 2026 was still under review as of October 2, 2026, so do not treat a proposed calculation as a finalized rate; confirm the current offer and enrollment status directly with Xcel before signing a solar contract.

For standard residential and small systems from 0.5 to 25 kW, the posted schedule lists a $0.0025 per kWh performance-based solar incentive and $100 per kW for paired storage, capped at $1,000 per customer. For income-qualified or disproportionately impacted community systems in that size range, the schedule lists a $1 per watt solar rebate plus $0.038 per kWh, and $100 per kW for paired storage capped at $1,000. Systems over 25 kW through 250 kW have a listed solar performance incentive of $0.02 per kWh.

The published schedule covers 2023–2026, and capacity and rebate allocations are released proportionally during the year, so availability is not guaranteed. The utility’s eligibility materials also limit system sizing relative to expected annual site consumption. Confirm the remaining allocation, eligibility, application timing, and current tariff with Black Hills Energy before construction or contract commitment.

Fort Collins Utilities offers residential electric customers a solar rebate of $300 per kW DC, up to $1,500, for a qualifying system of at least 0.5 kW. The system must be interconnected to the Fort Collins distribution grid and installed by a participating contractor; additions to existing systems may qualify under program rules.

To receive the solar incentive, the customer must assign the system’s renewable energy credits to the City of Fort Collins for 20 years. Check the city’s current application, equipment, interconnection, and contractor requirements before installation, since eligibility depends on program rules.

Fort Collins Utilities offers a rebate of $300 per kWh of battery capacity, up to $6,000, for a qualifying new battery of at least 6 kWh. The battery must be installed at a residential electric customer’s property and interconnected to the Fort Collins distribution grid under the city’s program requirements.

A battery may be installed with solar or without solar, and eligible additions to existing systems may qualify. The combined maximum for the city’s residential solar and battery rebates is $7,500. Confirm current equipment, contractor, interconnection, and application requirements with Fort Collins Utilities before installation.

For qualifying new solar interconnection applications under the rate effective April 1, 2026, Holy Cross Energy lists an incentive of $100 per kW, up to 25 kW, for a maximum payment of $2,500. Funding is first-come, first-served, and the member must obtain an HCE approval letter before construction to qualify.

Accepting the solar incentive assigns the system’s renewable energy credits to Holy Cross Energy. The program applies to eligible HCE members and qualifying net-metered systems; confirm approval, available funding, and current application requirements before beginning construction.

Members enrolling a battery in Power+ or Power+FLEX may receive up to $500 per enrolled kW, capped at $12,500. Alternatively, a member using the optional Time-of-Use rate may qualify for the lesser of $250 per kW of battery power or $100 per kWh of storage, also capped at $12,500. A member may enroll in only one of these battery incentive options.

Battery enrollment in the relevant rate or flexibility program is required, funding is limited, and portable or non-permanent systems—including vehicle-to-home systems—are excluded. Check Holy Cross Energy’s current terms, availability, and required operating conditions before purchasing or installing a battery.

LPEA offers a $1,000 rebate for qualifying batteries from 10 to 19.9 kWh and a $2,000 rebate for batteries of 20 kWh or larger. Eligible members in designated interconnection-limited zones may receive an additional $500 or $1,000, respectively, for a maximum zone-enhanced rebate of $3,000.

The interconnection application must have been submitted after January 1, 2025, the system must receive LPEA Permission to Operate, and the member must apply within 90 days of that permission. The battery and power-control system must be approved and operated to reduce grid demand from 4–9 p.m.; zone bonuses have additional operating requirements, including delayed charging in specified months. The rebate is available to eligible residential and commercial members.

The City of Boulder rebate returns approximately 15% of the City sales and use tax paid on eligible solar materials and permits; it is not 15% of the total project price. Since April 2026, the program also covers tax paid on qualifying permanently installed battery systems that operate in parallel with the utility grid.

Boulder residents and businesses may apply within 12 months after the City’s final inspection. The rebate is subject to funding availability, and eligibility depends on the equipment, taxes paid, and city program requirements. Keep itemized invoices and inspection records and review the city’s current application instructions.
