Solar Incentives in 2026: What Still Pays

The 30% residential credit expired at the end of 2025

That provision had a hard expiration date and was not extended. Systems placed in service in 2026 do not qualify, and eligibility already established on an earlier purchase is a separate question for your tax professional.

This matters because most solar marketing on the internet was written while the credit existed. If a 2026 proposal shows a line item cutting your net cost by roughly 30% and calls it a federal tax credit for you, that proposal is wrong — and the payback period and lifetime savings built on top of it are wrong too.

Third-party ownership still carries a federal benefit

The residential credit and the commercial clean electricity investment credit are different provisions. The residential one is gone; the commercial one is not. In a lease or power purchase agreement you do not own the system — a company does, and that company can claim the commercial credit on equipment it owns.

Whether any of it reaches you depends entirely on pricing. A credit the owner claims is not automatically your discount; it shows up, if at all, as a lower monthly payment or a lower rate per kilowatt-hour. The honest framing for 2026: buying costs more after tax than it did in 2025, while third-party ownership sits roughly where it was.

State and utility programs did not go away

These were never tied to the federal credit, and they are where most remaining value lives.

• State income tax credits. Smaller than the old federal one and usually capped.
• Rebates. Often administered in limited funding rounds that open and close.
• Property and sales tax exemptions. Quiet but substantial on a large purchase.
• Utility capacity rebates. Paid per watt or per system while a pool lasts.
• Battery and demand-response programs. In several markets these are now the most valuable incentive available.

Programs change on legislative and utility calendars, so treat any general list as a prompt to check your own state energy office and utility rather than a final answer.

Verify every incentive before you sign

Get the program name in writing — a category is not a program. Confirm who actually receives the money: you, the installer as an assigned rebate, or the system owner. Confirm the timing, since an upfront reduction and a credit claimed next year are very different for cash flow. Ask what happens if a funding pool empties between signature and installation. And if a federal residential credit appears on a 2026 purchase proposal, ask about it directly — it is the fastest way to learn how current your installer is.

Frequently asked questions

Could the residential credit come back? That is up to Congress, and no one can promise it. Decide on the incentives that exist when you sign.

Does the expiration affect batteries? Storage was covered by the same expired provision, so a battery bought in 2026 does not carry it either. Utility and state programs are where battery support now comes from.

Is solar still worth buying? Often, yes — the value was never mostly the credit, it was the electricity you stop buying. But the deal quality matters more now, which argues for multiple bids.

The bottom line

The 30% residential federal credit is gone as of 2026, and any proposal still showing it for a purchase is out of date. What survives is a patchwork worth real money: state credits and rebates, tax exemptions, utility and battery programs, certificate markets, and the commercial credit flowing through third-party-owned systems. Verify each by name, confirm who receives it, and let the electricity — not the incentive stack — carry the decision.
