Check the current IRS Residential Clean Energy Credit page before you count a federal solar tax credit in your budget. As reviewed on 2026-06-06, the IRS says the 30% Residential Clean Energy Credit applies to new, qualified clean energy property installed from 2022 through December 31, 2025, and says the credit is not available for property placed in service after December 31, 2025. This article is general education, not personal tax advice.

Solar tax credit claims move fast because Congress, IRS guidance, and tax-year forms can change the rule a homeowner relies on. A solar quote may mention a federal credit, but the quote is not the tax authority. Treat the IRS page, IRS forms, and a qualified tax professional as the sources to check before you sign a contract or adjust your payback worksheet.

What the IRS page says today

The IRS Residential Clean Energy Credit page is the source to start with for federal clean energy credit claims. On the page reviewed for this draft, the IRS says the Residential Clean Energy Credit equals 30% of the costs of new, qualified clean energy property for a home installed from 2022 through December 31, 2025. The same IRS paragraph says the credit is not available for property placed in service after December 31, 2025.

That date matters. If a system is sold, permitted, financed, installed, inspected, or placed in service in a different tax period than a homeowner expected, the tax result may not match the sales conversation. Do not assume a 2026 installation can use the old 30% federal credit language unless the current IRS page, the tax form instructions, and a qualified tax professional support that position.

RaysToWatts should not publish a blanket claim that the federal credit is available for new residential solar installs after the IRS cutoff. Before publication, re-check the IRS page again and update the review date.

Why placed-in-service timing matters

The IRS page says a homeowner must claim the credit for the tax year when the property is installed, not merely purchased. In plain language, paying a deposit, signing a contract, or ordering equipment is not the same as having a completed qualifying installation for tax purposes.

For a homeowner, the safe planning question is not only “Will this project qualify?” It is also “When will the qualifying property be installed or placed in service, and which tax-year form will apply?” That is a question for the current IRS instructions and a tax professional, not a solar salesperson.

Which property categories the IRS page lists

The IRS page lists clean energy property categories that may be qualified expenses, including solar electric panels, solar water heaters, wind turbines, geothermal heat pumps, fuel cells, and battery storage technology beginning in 2023. That list does not mean every project, every cost, or every homeowner qualifies.

For rooftop solar, the category most readers will care about is solar electric property. For solar batteries, the IRS page lists battery storage technology and also states that battery storage technology must have a capacity of at least 3 kilowatt-hours. A battery added to a quote still needs its own eligibility review.

What may count as a qualified expense

The IRS page says qualified expenses may include the costs of new clean energy property. It also says qualified expenses may include labor costs for onsite preparation, assembly, original installation, and piping or wiring to connect the property to the home.

It also draws a line around ordinary building parts. Traditional building components that mainly serve a roofing or structural function generally do not qualify. The IRS example says roof trusses and traditional shingles that support solar panels do not qualify, while solar roofing tiles and solar shingles can qualify because they generate clean energy.

This is one reason a homeowner should keep the invoice detail, not only the total contract price. A tax preparer may need to see which parts of a project are solar electric property, battery storage, labor, roof work, electrical work, or other costs.

Rebates and other incentives can change the cost basis

A state, utility, or manufacturer incentive can change the amount a homeowner uses in a tax-credit worksheet. The IRS page says public utility subsidies for buying or installing clean energy property are subtracted from qualified expenses. It also says some rebates are subtracted from qualified expenses when they meet listed conditions.

Do not count the full contract amount in a cost/payback worksheet and then subtract every rebate again without checking how the IRS says the incentive should be treated. Use the state and utility incentive worksheet in the /solar/state-utility-incentives/ guide, then bring the records to a tax professional.

What this article will not do

This article does not decide whether you personally qualify. It does not tell you which form lines to use, how to treat a mixed-use property, whether a landlord can claim a credit, how to handle a second home, or whether a lease or PPA changes eligibility for your situation.

It also does not use affiliate partner pages as tax authority. If an installer, marketplace, or affiliate page says a credit is available, verify that claim against the IRS page and current IRS instructions before you count it.

Records to gather before talking with a tax professional

Keep a simple file for the project. Include:

• Signed contract and change orders: These show what was purchased and whether the scope changed.
• Detailed invoices: Separate solar panels, battery storage, labor, wiring, roof work, and any non-solar work where the invoice allows it.
• Payment records: Keep deposits, progress payments, final payments, and financing documents.
• Installation and inspection records: Keep the installation date, final inspection documents, and permission-to-operate records if available.
• Incentive records: Save rebate approvals, utility subsidy documents, state program letters, and any payment confirmations.
• IRS source copies: Save the IRS page or instructions you relied on, plus the access date, because the rule is date-sensitive.

How to use the credit in a cost and payback worksheet

A federal credit is not the same as a cash rebate paid at installation. It is a tax credit subject to IRS rules, and the IRS page reviewed for this draft describes it as nonrefundable. That means a homeowner should not treat it as guaranteed cash back.

In the /solar/cost-payback/ worksheet, keep the federal tax credit as a separate line. Mark the amount as “verify with IRS and tax professional” until the homeowner knows the project date, eligible costs, incentive treatment, tax liability, carryforward treatment, and current form instructions.

If the current IRS page says the credit is no longer available for a later placed-in-service date, do not include the old credit in the payback estimate. A payback estimate built on an expired credit can make a quote look better than it is.

Battery storage caveats

The IRS page lists battery storage technology beginning in 2023 and says battery storage technology must have a capacity of at least 3 kilowatt-hours. That is a federal source point, but it is not a full eligibility ruling for every battery project.

If your solar quote includes storage, ask the installer to separate the battery equipment, battery installation labor, and any electrical work on the invoice. Then ask a tax professional how those costs fit the current IRS rules. For practical backup planning, use the /solar/solar-batteries-home-backup/ guide before assuming a battery will support an entire home.

Questions to ask before you count the credit

Ask these before you sign or before you update a savings worksheet:

1. What does the current IRS Residential Clean Energy Credit page say today? 2. What tax year will apply if the system is installed or placed in service on the expected timeline? 3. Which costs on the quote are clean energy property, labor to install or connect it, battery storage, roof work, or other work? 4. Which rebates, utility subsidies, or state incentives may reduce qualified expenses? 5. Who owns the system if it is financed, leased, or sold through a PPA? 6. Which IRS form and instructions apply for the tax year? 7. What records should the homeowner keep for the tax return?

Where quote comparison fits

Compare solar quotes only after you understand the tax-credit uncertainty. A quote-comparison service may help you collect multiple proposals, but it does not replace IRS guidance or tax advice.

Affiliate disclosure: RaysToWatts may earn a commission if you use a quote-comparison link. Compare quotes only after checking current tax guidance, local incentives, and the assumptions in the /solar/cost-payback/ worksheet.

FAQ

Is the federal solar tax credit still available for new systems?

As reviewed on 2026-06-06, the IRS Residential Clean Energy Credit page says the 30% credit applies to new, qualified clean energy property installed from 2022 through December 31, 2025, and says the credit is not available for property placed in service after December 31, 2025. Re-check the IRS page before publication or before making a tax decision.

Can I claim the credit when I buy the system, or when it is installed?

The IRS page says you must claim the credit for the tax year when the property is installed, not merely purchased. Ask a qualified tax professional how that applies to your project timeline.

Do batteries qualify?

The IRS page lists battery storage technology beginning in 2023 as a qualified-expense category and says battery storage technology must have a capacity of at least 3 kilowatt-hours. That does not decide every homeowner’s eligibility. Verify the current IRS page, the current form instructions, the battery specifications, and your own tax situation.

Can renters or second-home owners claim the credit?

The IRS page includes rules for main homes and certain second homes, and it also says landlords or other property owners who do not live in the home cannot claim the credit. This is a tax-specific question, so use the IRS page and a qualified tax professional before relying on it.

Do leases or PPAs qualify for the homeowner?

Do not assume. Ownership and tax-credit eligibility can differ between cash purchases, loans, leases, and PPAs. Review the current IRS guidance and the contract, then ask a tax professional before counting a credit in the /solar/solar-financing-options/ comparison.

Should I trust a solar sales page that says the credit is available?

No sales page should be your tax authority. Use the IRS page, IRS form instructions, and a qualified tax professional. Do not rely on affiliate partner pages for federal tax-credit claims.
