TPO Is the New Default. Most Reps Are Still Pitching Like It's 2024.

Here's a conversation happening on doors all over the country right now:

"Isn't the solar tax credit gone?" "Yeah, Congress killed it. But our pricing still works, trust me."

Wrong answer — and it loses winnable deals. The right answer is that the tax credit didn't die. It changed sides of the contract. And the reps who can explain that clearly are having a very different 2026 than the ones mumbling about pricing.

What actually happened to the credit

Two different tax credits always lived in residential solar, and only one of them died:

• Section 25D — the homeowner's credit for purchased systems. Cash and loan deals. Expired December 31, 2025. This is the funeral everyone attended.
• The commercial investment tax credit — claimed by the owner of a third-party-owned system: the lease or PPA provider. Still alive. Per SEIA's Q2 2026 Solar Market Insight report, safe-harbored TPO projects remain credit-eligible into 2030, and SEIA names TPO as the growth engine of the residential market for the next several years — with prepaid TPO products gaining momentum alongside classic leases and PPAs.

So when a homeowner asks whether the incentive is gone, the honest answer is: it's gone if you buy, it's alive if the system is third-party owned — which is why the market moved to third-party ownership. That's not spin. That's literally what the market did.

The market already voted

This isn't a prediction; the shift already happened. In 2026 industry survey data, 55% of installers now say TPO is their most popular financing option — ahead of both loans and cash — and nearly two-thirds expect TPO to be more than half of their 2026 volume. Three years ago the market was a loan monoculture. Today the volume play is leases and PPAs.

The customer math explains why. About half of solar buyers said they couldn't have afforded solar without the tax credit. Post-25D, a purchased system got meaningfully more expensive — but a TPO system's economics kept the credit baked in on the provider side, funding a monthly payment that can still beat the utility bill. Same roof, same panels, different contract, and one of them still carries a federal incentive.

And the thing the payment competes against keeps rising: US residential electricity is averaging around 18 cents/kWh in 2026, up from 17.29 last year, with data-center demand and grid spending pushing rates up faster than inflation. TPO's whole pitch is "pay less per month for power" — and the utility raises the bar it has to clear every year.

What a TPO-fluent rep actually knows

The gap between reps right now isn't hustle. It's fluency. The ones winning in TPO can do four things cold:

1. Explain ownership without flinching. The customer doesn't own the system; the provider does. Say it plainly and early — then anchor to what the customer actually wanted, which was never to own hardware. It was a lower, more predictable power bill. Reps who hide the ownership structure create tomorrow's cancellations.

2. Do bill-versus-payment math on the spot. The entire deal is one comparison: current average monthly bill vs. solar payment. Know the utility's current rates, know what they filed for next year, and show the gap honestly.

3. Defend the escalator honestly. Most PPAs step the rate up annually. The honest defense isn't "don't worry about it" — it's the utility's own track record. Rates rising at roughly double the rate of inflation make a modest fixed escalator an easy conversation if you actually have the numbers.

4. Know their own comp structure. TPO commissions are typically structured per watt by your org and the provider. If you don't know exactly how your check is computed on a lease versus what it was on a loan, you can't tell whether your org's TPO program is good — and in a market where TPO is most of the volume, that's your income you're not reading.

The org-level catch nobody mentions

Here's the structural problem: a rep can't sell TPO their org doesn't have.

Access to competitive lease and PPA products isn't evenly distributed. Providers work through installers and platforms with volume, clean funding rates, and real operations. A small independent org that could ride the loan wave in 2022 with nothing but a DocuSign account may simply not have a competitive TPO product on its menu in 2026 — which means its reps are pitching purchases with no incentive against competitors pitching payments with one. That's not a fair fight, and no amount of door skill fixes it.

This is the exact gap GRID exists to close. We're the $0 operating platform for solar dealers — the full toolset, plus a vetted installer network priced on the network's pooled volume, with TPO products in the lineup. We're paid on the install side of funded deals, so the platform costs your org nothing and we only win when your installs do. If your current shop can't put a competitive lease or PPA in your hands, that's a solvable problem — and solving it is a 20-minute conversation.

The bottom line

The 25D era rewarded reps who could create urgency around a disappearing credit. The TPO era rewards reps who can explain a contract structure clearly and do honest math against a rising utility bill. Same doors, different skill — and right now most of the industry hasn't retrained, which is precisely the opportunity.

The credit isn't dead. It changed sides. Go be one of the few reps who can explain that.
