Can You Still Finance Solar With Zero Down in 2026?

Zero-Down Financing Still Exists, Just Not the Same Deal Behind It

Zero-down solar financing has not disappeared in 2026. Both dedicated solar loans and lease or power purchase agreement (TPO) structures can still be arranged with no money down at signing, the same as in prior years. What a homeowner needs to understand is that “zero down” describes the payment structure, not the tax outcome, and those two things no longer move together the way they used to.

Why the Tax Math Changed for a Zero-Down Loan Specifically

The IRS states plainly that the residential clean energy credit “is not available for any property placed in service after December 31, 2025.” That cliff came from the One Big Beautiful Bill Act, which repealed Section 25D outright rather than phasing it down. A homeowner who finances a system with a loan, even a $0-down loan, owns the system outright, and an owned system installed in 2026 gets zero federal credit under that rule. That is true whether the homeowner put nothing down or paid a large deposit, ownership is what determines the tax outcome, not the down payment amount.

Why a Zero-Down Lease or PPA Still Carries Something the Loan Doesn’t

A lease or power purchase agreement puts ownership with the third-party provider, not the homeowner, which is exactly the structure Section 48E is written for. A TPO provider can still claim that credit and, at its own discretion, price the value into the monthly rate or per-kilowatt-hour charge it offers the homeowner. That is one reason third-party ownership is projected to reach 65% of reps’ books in 2026, up from 44% in 2025, as the tax math has shifted in its favor relative to ownership-based financing.

What to Ask Before Assuming Two “Zero Down” Offers Are the Same

Ask directly whether a $0-down offer is a loan, which leaves the homeowner owning the system with zero federal credit in 2026, or a lease or PPA, which leaves a third party owning it with the possibility of 48E value priced into the rate. The sticker language, “no money down,” can be identical on both, while the underlying ownership and tax consequences are not, and that difference is worth more to a homeowner’s total cost than the down payment number alone.
