Prepaid solar leases
Pay most of the contract at signing, then little or nothing monthly. A product that barely existed two years ago and is now being pitched hard — for a specific and understandable reason.
Why this product appeared in 2026
A cash purchase used to come with a 30% federal credit. It no longer does. A prepaid lease lets a household put down roughly the same money while the financier — who still owns the system — claims the commercial §48E credit and prices some of it back into the lump sum. It is a workaround for the expiry of §25D, structured to keep federal money in the deal.
Where it sits between the other options
| Cash purchase | Prepaid lease | Standard lease | |
|---|---|---|---|
| Upfront cost | Full | Most of it | None |
| Monthly payment | None | Little or none | Yes, usually escalating |
| Federal credit | None | Indirect (§48E) | Indirect (§48E) |
| You own it | Yes | Not during the term | No |
| Maintenance | Yours | Provider | Provider |
| Counterparty risk | Low | High — money out, asset not yours | Moderate |
The comparison that decides it
A prepaid lease is worth considering only if the lump sum is meaningfully below what the same system costs to buy outright. That gap is the credit pass-through, and it is the whole value proposition.
So get both quotes for the same system from the same installer: the cash purchase price and the prepaid lease price. If the prepaid figure is not clearly lower, the provider is keeping the credit and you are paying purchase money for a leaseholder's position.
The risk that is genuinely different here
With a standard lease, a failed provider is annoying. With a prepaid lease, you have already handed over most of the money and you do not own the asset. In a market where installation volumes are down sharply, a major national installer has withdrawn from a third of its markets, and at least one multi-state installer has filed for bankruptcy protection, that asymmetry deserves weight.
Before prepaying, establish:
- Who legally owns the system, and is it the entity taking your money?
- Will the contract be sold to another owner, and can it be?
- What is your position if that owner becomes insolvent?
- Does ownership transfer to you at end of term — in writing?
- What is the placed-in-service commitment, given the 2027 §48E deadline?
Model it before you decide
The comparison calculator handles a prepaid structure: set the lease upfront payment to the lump sum and the monthly payment to zero. Compare the resulting net present value against the cash purchase for the same system. If they are close, the pass-through is small and the extra risk is not being paid for.
Common questions
What is a prepaid solar lease?
You pay a large lump sum at signing — often close to what a purchase would cost — and then pay little or nothing monthly for the rest of the term. The financier still owns the system, so it still claims the §48E commercial credit and prices that into your lump sum.
Why would I prepay instead of just buying?
Because buying no longer carries a federal credit and prepaying indirectly does. That is the entire reason this product exists in 2026. Whether it beats a cash purchase depends on how much of the credit the provider actually passes through, which is not disclosed.
Do I own the system at the end of a prepaid lease?
Sometimes, and that is the clause to check. Some prepaid structures transfer ownership at the end of the term; others offer a buyout at fair market value. Do not assume — get it in the contract.
What is the catch?
You have paid nearly everything upfront but you do not own the asset, which means you carry the cash outlay of a purchase with the flexibility constraints of a lease. If the provider fails during the term, your position is weaker than an owner’s.
