Calculators / Solar incentives calculator

What incentives can I actually get?

A buyer gets no federal credit in 2026. What survives is the state layer, and it is thin — so this shows what you would actually receive, with the statute or programme each figure came from.

Three layers, and one of them just went away

Household solar in the United States has historically been supported at three levels: a federal tax credit, a state credit or rebate, and in some states a payment for the electricity produced. In 2026 a buyer gets nothing from the first. What remains is the state layer, and it is thin — most states we publish offer a buyer nothing at all.

That is why this calculator shows a total rather than a headline percentage. A percentage of a credit you cannot claim is not an incentive, and a programme that pays over fifteen years is not the same money as one that reduces the invoice. The table above separates them by when the money actually arrives.

An incentive you cannot claim is worth nothing

Two conditions decide whether a credit reaches you, and neither is modelled, because both are personal:

A third condition applies to programmes that pay for production: the money arrives while the system generates, so it depends on the system still being there and still working. That is a different kind of promise from a credit on a tax return, and it belongs in a different mental column.

Where each figure comes from

Every incentive above is recorded from the statute, tax department page or programme document that grants it, with the date we read it. Where a programme exists but we cannot model it faithfully — an unusual schedule, a rule that depends on the individual utility — the calculator raises a flag under the results rather than quietly leaving it out. Both directions of that error matter: overstating what you will receive and understating it are the same failure.

The full list across the states we publish, with sources, is in state solar incentives in 2026. What changed federally, and the dates that decide which year you fall into, is in the tax credit guide.

Questions

Why is the federal credit zero for a buyer in 2026?
Because the residential credit expired for systems placed in service after 31 December 2025. The commercial credit a third-party owner claims is separate and still available, which is why a lease shows a credit above and a purchase does not. This is the single largest change to household solar economics in a decade, and many calculators have not made it.
A credit and a rebate are not the same thing?
No, and the difference decides whether you get the money. A rebate is cash off the price. A credit reduces the tax you owe, so a household whose liability is smaller than the credit receives only what it owes, and one that owes nothing receives nothing. Where a credit carries forward to later years, that is a feature of the specific programme and worth confirming.
What is a payment for production?
Some states pay for the electricity a system generates rather than discounting what it cost. Illinois and New Jersey both do, on different schedules, and the money arrives over years rather than at installation. The model pays these out on the schedule the programme documents specify and shows the total above.
Why is my utility rebate not listed?
Because this list is statewide programmes only. Utility and municipal rebates exist, change often, and are frequently first-come until a budget runs out; we do not publish figures we cannot verify against a primary source and keep current. Check your own utility directly - it is one of the few places a genuinely large incentive still hides.

The other calculators

All of them run the same engine on the same data, so two can never disagree. They differ in what they put first.

A screening estimate from published data, not a quote and not tax or financial advice. Every input is listed under the results with the source it came from and the date it was read; the formulas are on the methodology page. Confirm against real quotes, and with a professional, before relying on any figure here.
