TL;DR: A prepaid solar lease in California lets you pay once, up front, for a system a third party owns for about 5 to 6 years. That owner claims the federal 48E commercial credit that homeowners lost after 2025 and passes part of it to you, typically as a 30% to 35% discount off the cash price. Systems that start construction after July 4, 2026 must be placed in service by Dec 31, 2027 to keep that credit.
Key takeaways
- Prepaid leases exist because the 25D homeowner credit ended for installs completed after Dec 31, 2025, while third-party owners can still claim 48E.
- In our example, an 8 kW system drops from $20,160 cash to $14,112 prepaid, a $6,048 difference.
- Ownership usually transfers around year 6, often at fair market value. A $0 buyout is not guaranteed.
- Selling before transfer means clearing a UCC-1 filing through a lease assumption or early buyout.
- Solar projects that started construction after July 4, 2026 lose 48E if placed in service after Dec 31, 2027.
Here is the strangest thing about buying solar in California in 2026: the cheapest way to end up owning your panels might start with a lease. Since the homeowner tax credit ended, a prepaid lease is often the only way a California homeowner can still capture some of the federal 30% credit. The catch is that the discount has a clock on it, and the contract has fine print that a cash purchase does not.
What is a prepaid solar lease?
A prepaid solar lease is a lease where you pay the full lease cost on day one instead of monthly, often about 65% to 70% of the cash price, and a third party owns the system for an initial hold period of about 5 to 6 years. After the hold, ownership typically transfers to you.
During the hold, the leasing company (the third-party owner, or TPO) owns the equipment, claims the federal credit, charges you less than a cash price, and usually covers monitoring and maintenance.
How it works, step by step:
- Design. The installer sizes the system to your usage, roof and shading, same as a cash job.
- Contract. You sign a lease with the TPO, which is the legal owner.
- Prepayment. You pay the discounted amount up front, from savings, a HELOC or a separate loan. No monthly solar payment after that.
- Credit and hold. The TPO claims the 48E credit and owns the system for roughly 5 to 6 years.
- Transfer. You buy the system under the contract’s purchase option and it becomes yours.
A prepaid PPA works the same way, except you prepay for expected electricity instead of the equipment. Our breakdown of prepaid solar PPAs covers the Maxwell Power (formerly HDM) product.
Why are prepaid solar leases popular in California in 2026?
Prepaid leases took off because the Section 25D homeowner credit is gone: the IRS says the credit is not allowed for expenditures made after Dec 31, 2025, and an expenditure counts as made when installation is completed (IRS FS-2025-05). A system you buy for cash in 2026 gets no federal credit.
A leasing company that owns a residential system is a business, so it can still claim the Section 48E Clean Electricity Investment Credit, a 30% base credit. A prepaid lease is how part of that credit reaches you. The 2025 law cut 48E for some leased property, but leased residential solar electric property was exempted.
It matters more in California than most states. Under the CPUC’s Net Billing Tariff (NEM 3.0), exported solar earns far less than it did under NEM 2.0, so the upfront price is a bigger share of your payback math. And many California homes need 7 to 10 kW, so a percentage discount turns into real dollars.

How much does a prepaid lease save vs paying cash?
Verified California prepaid lease offers run about 30% to 35% below the cash price for the same system. On an 8 kW system at the current California average of about $2.52 per watt, a 30% discount saves $6,048.
Example only, not a quote. Your price depends on roof complexity, equipment, any main panel upgrade, and the provider’s discount.
- System size: 8 kW (8,000 watts)
- California average installed price: $2.52/W before incentives (market average, October 2026)
- Cash price: 8,000 x $2.52 = $20,160
- Federal homeowner credit on a 2026 cash purchase: $0 (25D ended)
- Prepaid lease discount used in this example: 30%
- Prepaid lease price: $20,160 x 0.70 = $14,112
- Difference: $6,048, or about $0.76 per watt
Prepaid solar lease savings example: 8 kW system in California (illustrative)
| Scenario | Price per watt | Upfront cost | Federal credit to homeowner | Net cost to homeowner |
|---|---|---|---|---|
| Cash purchase, 2026 | $2.52 | $20,160 | $0 | $20,160 |
| Prepaid lease, 25% discount | $1.89 | $15,120 | $0 | $15,120 |
| Prepaid lease, 30% discount | $1.76 | $14,112 | $0 | $14,112 |
| Prepaid lease, 35% discount | $1.64 | $13,104 | $0 | $13,104 |
Source: $2.52/W California average installed price, market data updated Oct 30, 2026; discount range from published prepaid lease offers by California providers. Homeowner credit is $0 because 25D ended for installs completed after Dec 31, 2025 (IRS FS-2025-05). Example only, not a quote.
Takeaway: in this example, a prepaid lease at a 25% to 35% discount (25% shown as a conservative case) costs $5,040 to $7,056 less up front than paying cash for the same 8 kW system.
Two caveats. The discount is off the provider’s price, which may not match the market average, so compare final dollars. And the buyout at transfer can claw back part of the discount. For how these numbers fit into broader pricing, see our breakdown of solar cost in California.
Prepaid lease vs cash vs loan vs monthly lease: which costs less?
A prepaid lease sits between a cash purchase and a monthly lease: you pay up front like a cash buyer, but you do not own the system until about year 6, and you get a discount a cash buyer cannot get in 2026.
Solar financing comparison for California homeowners (2026)
| Option | Upfront cost | 25-year cost pattern | Who owns it | Warranty and maintenance | Buyout and home sale |
|---|---|---|---|---|---|
| Cash purchase | Full price (e.g. $20,160) | Lowest after payoff, no credit in 2026 | You, from day one | Manufacturer plus installer workmanship | No buyout; system transfers with the house |
| Solar loan | $0 to low | Full price plus interest | You, from day one | Manufacturer plus installer workmanship | Loan must be paid off or assumed at sale |
| Monthly lease or PPA | $0 to low | Highest; payments for up to 25 years, may escalate | Leasing company | Included for the term | Buyer must assume the lease or you buy out |
| Prepaid lease | About 65% to 70% of cash price | Low; one payment plus any buyout | Leasing company until about year 6 | Included until transfer, then you | Purchase option around year 6; assumption or early buyout before that |

What happens in year 6: buyout and ownership transfer?
Ownership usually transfers around year 6, after the leasing company holds the system for 5 years to protect its tax credit. The transfer price is set by your contract, and it is often fair market value, not $0.
Why 5 years? A business can have part of its credit recaptured if it disposes of the property early.
What to check in the purchase option:
- Price formula. Fixed dollar amount, percentage, or “fair market value”? Fair market value on a 6-year-old system may be modest, but it is not zero, and the contract should say who appraises it.
- Optional or automatic. Some contracts transfer automatically for a nominal amount. Others make you exercise an option within a window. Ask what happens if you do nothing.
- Warranty handoff. After transfer, maintenance is yours. Confirm the manufacturer warranties and the installer’s workmanship warranty carry over.
- Early purchase. Some providers allow purchase from year 5. Get the exact year and price.
If a salesperson promises you will own it free in year 6, get it in the contract.
What happens if you sell your house with a prepaid lease?
If you sell before ownership transfers, your buyer either takes over the lease or you buy the system out early, and the leasing company’s UCC-1 filing stays on record until transfer. After transfer, the system is yours and sells with the house like any other fixture.
The UCC-1 is a fixture filing showing the leasing company owns the equipment. It is not a mortgage, but it shows up in title searches.
A prepaid lease is usually easier to transfer than a monthly lease, because the buyer has no payment to qualify for. The leasing company still has to approve it:
- Call the leasing company when you list and request its transfer packet.
- Disclose the leased equipment to buyers.
- Buyer assumes the remaining hold period and the purchase option, or you get a written early buyout figure before opening escrow.
- Confirm the UCC-1 is terminated once you own the system.
Home-sale terms on prepaid leases are not standardized across providers yet, so read the transfer and assignment section before you sign.
Will prepaid lease discounts last past 2027?
Probably not in their current form. Under Section 70513 of the 2025 tax law (Public Law 119-21), now codified at 26 U.S.C. 48E(e)(4), solar facilities that begin construction after July 4, 2026 lose the 48E credit if they are placed in service after Dec 31, 2027. No credit for the leasing company means nothing to pass on as a discount.
What that means in November 2026:
- A contract signed now almost certainly covers a system that begins construction after July 4, 2026, so it must be placed in service by Dec 31, 2027.
- Some providers safe-harbored equipment before July 2026, which may give those systems more runway. Ask in writing whether yours qualifies.
- The rules were litigated. On June 6, 2026, a federal district court in D.C. vacated Notice 2025-42, restoring the earlier IRS tests for proving start of construction. The statutory dates did not change.
- Foreign-entity rules apply to facilities starting construction after Dec 31, 2025, which can narrow the equipment a provider offers.
Our read: 2027 is the year to get a prepaid lease installed, not just signed. Permitting and interconnection take weeks to months. Ask what happens to your price if the system misses Dec 31, 2027.
Is a prepaid solar lease worth it?
For many California homeowners in 2026, yes: a prepaid lease is often the only way to get a 30% to 35% federal-credit-driven discount on a home solar system, and in our 8 kW example that is about $6,000. It is worth it if you plan to stay at least 6 years and the contract has a clear, written buyout.
Think twice if you expect to sell within a few years, want full control of equipment from day one, are offered a “fair market value” buyout with no formula, or cannot get a clear answer on what happens if the install slips past 2027. Adding a battery? Under NEM 3.0, storing midday solar for evening use is where much of the value sits, so ask whether storage is in the prepaid structure or a separate purchase. Our solar installation page covers how we size both.
Frequently asked questions
You pay a discounted lump sum up front, often about 65% to 70% of the cash price, and a leasing company owns the system for about 5 to 6 years while it claims the federal 48E credit. After that hold period, ownership transfers to you under the contract’s purchase option.
A monthly lease can run 25 years with escalating payments. A prepaid lease means a large upfront payment, a buyout that may be at fair market value, limited equipment choice, and less leverage if the system underperforms, since you already paid.
It usually costs the most over its life, because you keep paying after the system has paid for itself. It can make sense if you cannot pay up front. A prepaid lease shortens third-party ownership to about 6 years and usually costs much less in total.
Buyers hesitate to take over a monthly lease because it adds a payment, needs credit approval, and puts a UCC-1 filing on title. A prepaid lease removes the payment, but the buyer still needs the leasing company’s approval until transfer.
No, not directly. The 25D homeowner credit ended for installs completed after Dec 31, 2025. With a prepaid lease, the leasing company claims the 48E credit and passes part of its value to you as a lower price. That is the whole reason the discount exists.
