How to sell solar after the federal tax credit

For fifteen years the federal residential credit did a large part of solar's selling. It gave a rep a number to write at the bottom of a page, it created urgency every December, and it made a payback calculation work that otherwise would not have. That tool is gone, and the companies still reaching for it are the ones whose close rate fell off a cliff in January.

What actually changed on 1 January 2026?

The One Big Beautiful Bill Act, signed 4 July 2025, repealed Section 25D, the Residential Clean Energy Credit. The credit is not allowed for any expenditure made after 31 December 2025, and the IRS treats an expenditure as made when the original installation is completed, not when the contract was signed or the deposit taken. A job sold in November 2025 and commissioned in February 2026 does not qualify. See the IRS guidance on the change.

Why did the cash pitch stop working?

A cash or loan purchase used to carry an implicit discount of nearly a third, claimed back the following April. Take that away and the same system costs the same homeowner meaningfully more, while the monthly saving it produces has not moved. Payback periods that read as seven or eight years now read as ten or eleven, and eleven years is past the point where most homeowners stop listening.

The instinct is to discount your way back to the old number. Do that and you fund the whole change out of your own margin, on every job, forever. The companies handling this well have not cut price. They have changed which number is on the page.

Where does the 30% still live?

Section 48E, the commercial investment credit, was not repealed alongside 25D. When a finance company owns the system on a homeowner's roof under a lease or a power purchase agreement, that company is the owner for tax purposes and claims the credit itself, then prices it into the monthly payment it offers. The homeowner never touches a tax form and still sees the benefit, arriving as a lower number every month instead of a refund once.

This is the single most important thing for a sales team to understand right now, and it is routinely explained badly. The credit did not vanish from residential solar. It moved, from the homeowner to the asset owner, and it only reaches the homeowner if you are selling a product where somebody else owns the asset.

The clock you are now selling against

48E is not permanent either, and the dates are unforgiving. Projects that began construction before 4 July 2026 have until the end of 2030 to be placed in service. Anything beginning construction after that date has to be placed in service by 31 December 2027. That first date has already passed, which means most work being sold today sits in the accelerated lane with a hard 2027 deadline on it.

The five per cent cost safe harbor that developers used to rely on was largely eliminated, leaving the physical work test as the practical route to establishing that construction began. If your finance partner is claiming safe-harbored equipment, ask them to put the basis in writing.

How do you rebuild the pitch around monthly cost?

A tax credit is a promise about next April. A monthly payment against a utility bill is a promise about next month, and it is the easier of the two to believe. The pitch that is working is a straight comparison of two numbers the homeowner already recognises: what they pay the utility now, and what they would pay instead.

1. 01

   Lead with the current bill

   Ask for twelve months of it before you quote anything. The bill is the only number in the conversation the homeowner already trusts, and every argument you make should be anchored to it.

2. 02

   Show the replacement payment beside it

   One line against another, same units, same month. Not a twenty-year net present value. If the replacement payment is lower, that is the whole pitch and it needs no decoration.

3. 03

   Name the escalator

   Utility rates rise and a fixed payment does not. The gap between the two lines widening over time is the real argument, and it survives the credit's absence entirely.

4. 04

   Handle ownership honestly

   A lease is not a purchase and the homeowner should know it. Say who owns the equipment, what happens at end of term, and what happens if they sell the house. Getting this wrong creates a cancellation three weeks later.

What to stop saying immediately

• "You will get 30% back from the government." Not for a cash or loan purchase installed this year. Said to a homeowner who then files and does not receive it, this is the kind of claim that produces a complaint rather than a referral.
• "The credit might come back." Nobody knows, and building a close on a guess about future legislation is not a close, it is a deferral.
• "Buy before the deadline." The 25D deadline has passed. Manufactured urgency pointing at a date that already went by is transparent, and homeowners check.
• Anything still on your website about the 30% credit. A page that has not been updated is telling every visitor you have not noticed the largest change in your industry in a decade.

That last one is worth an afternoon this week. Most solar sites still carry a tax credit banner, a calculator with the credit baked in, or a blog post from 2024 that ranks. See what to put on a solar company website for the pages that actually need to exist, and how to write solar website copy for the tone that works once the discount is gone.

What has not changed

Speed to lead still decides who wins. The company that calls back first still closes the majority of shared enquiries, and that advantage got larger, not smaller, when the sale got harder. A market where everyone's close rate dropped is a market where the cheapest remaining improvement is answering faster. See speed to lead for solar companies.

Reviews still carry more weight than any incentive, because the objection you are now facing is about trust in a bigger monthly commitment rather than trust in a rebate. And the follow-up sequence matters more than it did, because deals that used to close in one visit now take three.

The credit was never the reason people went solar. It was the reason they went this year instead of next.

That distinction is the whole of it. Demand did not disappear on 1 January, urgency did. Urgency is something a sales process can manufacture honestly, through a rate escalator, a finance window that genuinely closes, or an install calendar that genuinely fills. A tax credit was simply the laziest available version of it.
