Federal Solar Tax Credit in 2026: What Still Applies

The federal Residential Clean Energy Credit (often called the solar ITC) was 30% of qualifying solar equipment costs for homeowner-owned systems installed from 2022 through December 31, 2025. The IRS says the credit is not available for any property placed in service after December 31, 2025. Roof replacement alone was not eligible even while the credit existed. This October 2026 guide explains what still applies, what does not, and what to verify with a tax professional before you bake credit math into a loan.

Pair this with our solar ROI calculator (defaulted to 0% for a 2026 install), HEAR rebates by state, and roof-before-solar sequencing. For North Carolina utility and property-tax specifics, see NC solar incentives.

2026 federal solar tax credit basics

• 2026 installs: 0%. If the original installation is completed after December 31, 2025, the credit does not apply — including projects paid for in 2025 that were not finished until 2026. Source: IRS Residential Clean Energy Credit.
• 2022–2025 installs: 30% of eligible clean-energy property costs. Claim it on Form 5695 for the year installation was completed. Unused non-refundable credit can carry forward.
• Eligible property (when the credit applied): Solar PV, qualifying battery storage, and related equipment. Do not rely on a sales deck.
• Timing: The IRS treats the expenditure as made when original installation is completed. Keep install and permission-to-operate dates.
• Ownership: Leases and many PPAs meant the homeowner did not claim the residential credit. For a 2026 install, do not assume you or the solar company still gets this homeowner credit.

What the ITC usually does not cover

• Asphalt roof replacement without qualifying solar equipment
• Cosmetic upgrades unrelated to the energy system
• Equipment you do not own (leased arrays)
• Costs that fail IRS eligibility or documentation rules — confirm with a preparer

Roof work tied to solar mounts may be a gray area depending on scope — get written allocation from your installer and CPA, not verbal promises.

Batteries and add-on equipment

Standalone storage must meet IRS capacity and charging rules to qualify. Door-to-door bundles marketing home battery backup solar without specs are a review flag — model batteries as their own ROI line, not a free add-on.

HEAR & efficiency credits — separate programs

HEAR and HOMES are state-run rebates, not the expired 30% tax credit. The Energy Efficient Home Improvement Credit also ended for property placed in service after December 31, 2025. Check live rebate status in our HEAR home energy rebates guide before you commit to equipment scope — a portal can be open in one state and paused in the next.

Utility rules now drive payback

Net metering, time-of-use rates, and interconnection timelines are the dollars left after the residential credit ended. A shaded array or a bad tariff class does not get rescued by a credit that no longer applies. Run conservative production assumptions in the solar hub with the credit set to 0% unless your system was finished by December 31, 2025.

Pre-install checklist

1. Set the credit to 0% for a 2026 install. If installation was completed by December 31, 2025, confirm any remaining credit or carryforward with a CPA
2. Capture 12 months of usage data before sizing
3. Get roof remaining life in writing if mounts penetrate shingles
4. Read lease vs loan ownership clauses before signing
5. File warranties and IRS documentation in one folder after PTO

Payment path matters too — compare financing options on total dollars paid, not monthly payment alone.
