Solar incentives in 2026: what changed and how to keep closing deals

For years, the 30% federal tax credit was every solar installer's best closing tool. "You get 30% back" did half the selling for you. In 2026, that tool is gone — and the installers who adapt their pitch are the ones who keep closing.

On July 4, 2025, the One Big Beautiful Bill Act repealed the federal residential solar tax credit (Section 25D). For any system a homeowner buys with cash or a loan and places in service after December 31, 2025, the federal credit is $0 — no phase-down, no partial credit.

That sounds like bad news. But the incentives that remain are still substantial — and most of your prospects have no idea they exist. Your job in 2026 is to know them cold and present them clearly. Here's the playbook.

Leases and PPAs: the 30% credit didn't fully disappear

Here's the nuance most homeowners miss. The residential credit (Section 25D) is gone, but the commercial credit (Section 48E) is still alive. When a third party owns the system on the roof — through a lease or a power purchase agreement (PPA) — that owner claims the 30% commercial credit and passes the savings on as lower monthly payments.

In other words, a homeowner can still benefit from the 30% credit indirectly, as long as the system is third-party owned. For many installers, steering part of the offer toward lease or PPA financing is the single biggest lever to keep deals alive in 2026.

There's a deadline, though. To qualify, these projects generally need to begin construction by July 4, 2026. That makes timing a real selling point: "If we start now, your system can still capture the 30% credit through financing" is one of the strongest lines you can use this year.

State tax credits: still worth thousands

Several states still offer their own income tax credit, and these didn't change with the federal repeal. If you operate in one of them, this is now one of your most powerful arguments. About seven states currently offer a state income tax credit — a few examples:

• South Carolina: 25% of system cost, no cap
• Hawaii: 35%, up to $5,000
• New York: 25%, up to $5,000
• Arizona: 25%, up to $1,000
• Massachusetts: 15%, up to $1,000
• Plus a few others (New Mexico, Utah)

These credits stack with other incentives. Always check the current rules in your state and build the state credit into the net price you show — "$8,500 after your state credit" lands far harder than the sticker price.

Net metering: the everyday savings engine

Net metering is what credits a homeowner for the surplus electricity their panels send back to the grid. It's not a one-time rebate — it's the mechanism that keeps the monthly bill low for 20+ years, which makes it central to your ROI pitch.

The catch is that it varies enormously by state. Full retail net metering credits every exported kilowatt-hour at the full retail rate — the best case. Other states have shifted to avoided-cost or net-billing rates that pay far less. Know exactly how your state treats exports, because it changes the payback math you put in front of a prospect.

SRECs: recurring income in the right states

In states with a Solar Renewable Energy Credit (SREC) market — New Jersey, Maryland, Massachusetts, Illinois, Ohio, Pennsylvania, and a few others — utilities are required to buy SRECs to meet clean-energy mandates. Your customer earns roughly one SREC for every megawatt-hour produced and can sell it for extra income, anywhere from about $10 to $350 per SREC depending on the market.

If you sell in an SREC state, this is a recurring-revenue story most prospects have never heard. Framing it as "your roof pays you back every year" can be the detail that tips a hesitant buyer.

Don't forget property and sales tax exemptions

Beyond credits, many states exempt solar systems from added property tax (so a system that raises your home's value doesn't raise your tax bill) and from sales tax on the equipment. They're easy to overlook, but they're real dollars — and stacking every small incentive is how you rebuild the value the federal credit used to provide.

How to sell solar in 2026

The federal credit did a lot of the persuading for you. Now the persuading is your job — and that's actually an opportunity, because most of your competitors will keep quoting sticker prices and watching prospects walk away.

• Lead with financing: present lease and PPA options that still capture the 30% commercial credit
• Stack every remaining incentive — state credit, net metering, SRECs, tax exemptions — into one clear net number
• Use the rising cost of electricity as your anchor: solar is a hedge against bills that keep climbing
• Create urgency with the July 4, 2026 construction deadline for credit-eligible financed systems
• Show personalized numbers, not national averages — a calculator that bakes in your state's incentives closes far better

The rules changed, but the fundamentals didn't: solar still saves homeowners money over time. The installers who win in 2026 are the ones who can explain — clearly, with real numbers — exactly how. Master the incentives that remain, and you turn a tougher market into an edge over the competitors who didn't bother.

The 30% federal credit isn't your closer anymore. Your clarity is. The installer who explains the 2026 incentives best wins the deal.
