Prepaid solar lease in California: what you pay, and what you still don't own

How a prepaid lease differs from a monthly lease

The CPUC describes a standard lease this way: “you will make scheduled monthly payments in exchange for all the electricity the system produces,” and “the solar provider owns the system on your property.” A prepaid lease moves some or all of those scheduled payments to the start. The CPUC’s question list for lease and PPA shoppers includes: “Is there an option to make a down payment to reduce my monthly payments (for a lease) or kilowatt-hour rate (for a PPA)?” (CPUC, California Solar Consumer Protection Guide, checked September 23, 2026.)

What does not change is who owns the system. That one fact decides most of what follows: the provider maintains it, the provider’s contract controls what happens at a sale, and the equipment is not yours at the end unless the contract says you can buy it.

How much does a prepaid solar lease cost?

No public agency publishes lease prices, so there is no honest statewide number to give you. What you can do is make the offer answer the CPUC’s first two questions: “What is the total cost of the solar system or solar energy over the entire course of the contract?” and “How much will I pay up front, how much over time, and for how long?”

Then run three comparisons on the same system size and the same roof layout:

1. Prepaid versus monthly. Add up every monthly payment the standard lease would charge over the term, escalator included. Compare that total with the prepaid price. Paying early means giving up the use of that money now.
2. Prepaid lease versus cash. If the prepaid price is close to the cash price for the same system, you are paying about the same money for a system you will not own. The gap is what you pay for the provider handling repairs.
3. Prepaid versus your utility bill. A prepaid lease leaves a smaller utility bill, not a zero one. The CPUC says savings estimates “do not guarantee savings.” Ask for the bill the proposal expects you to keep paying.

What sets a standard lease payment is covered in what a California solar lease costs. For the equipment price you would pay to buy instead, see California solar panel cost and sizing.

Prepaid lease or buy outright: what is actually different

• Maintenance. Under a lease, the CPUC says the “solar provider is responsible for all monitoring, maintenance, and repairs.” When you buy, those are yours.
• Federal tax credit. None either way for a system installed now. The IRS says the Residential Clean Energy Credit “is not available for any property placed in service after December 31, 2025” (IRS, checked September 23, 2026). What California still offers is in the state’s solar incentives in 2026.
• Property tax. No difference under the current rule. The Board of Equalization says the system “is excluded whether it is leased or owned” (BOE FAQs, checked September 23, 2026).
• Provider risk. The CPUC lists it as a risk: “Solar provider could go out of business during the contract period.” A monthly customer stops paying when service stops. A prepaid customer has already paid. Before you prepay, ask what happens to repairs, any production guarantee and your contract if the company is sold or closes.

Selling a home with a prepaid lease

The CPUC’s rule of thumb for any lease or PPA: “If you sell your house before the lease or PPA contract is over, you will have to pay the solar provider the remainder of the value of the lease or PPA or transfer the contract to the new property owner.” With a fully prepaid lease there may be little value left to pay, which is the main selling point of prepaying. The transfer still runs through the contract, and the CPUC suggests asking, “Are there fees for transferring the lease, PPA, or PACE financing to a new homeowner?”

Does prepaying help the sale price? The only California study found no clear answer. Berkeley Lab looked at 20,106 California home sales from 2011 to 2013, including 113 with third-party-owned systems, 17 of them prepaid or more than 75% prepaid. It “fails to uncover statistically significant premiums for TPO PV homes nor for those with pre-paid leases as compared to non-PV homes.” It did find a larger premium for prepaid systems than for non-prepaid ones, but that difference was not statistically significant (LBNL-1007003, checked September 23, 2026).

The step-by-step for a sale is in selling a California home with a lease or PPA.

What happens at the end of a prepaid lease

Prepaying does not change what the contract says about year 20 or 25. Ask, in writing, before you pay:

• Can you renew, buy the system, or have it removed at the end of the term, and at what price?
• Who pays for removal and for repairing the roof where the mounts were?
• If you want out early, will you owe a balloon payment or early termination fee? The CPUC asks this question directly.
• Is part of the prepayment refunded if the system is removed, damaged or shut off for a long period?
• Does the provider offer a minimum energy guarantee, which the CPUC calls “common with leases and power purchase agreements”, and does it still apply once you have prepaid?

If you are thinking about leaving a lease you already have, read what happens if you stop paying a solar lease before you act.

Prepaid lease or prepaid PPA?

Both put the payments upfront and both leave the provider owning the system. The difference is what the prepayment buys. A lease prepays scheduled payments; a PPA prepays electricity at a per-kWh price, which the CPUC describes as paying “for all the power the solar system generates (at a fixed per-kilowatt-hour rate).” Ask a prepaid PPA provider what happens if the system produces more or less than the amount you prepaid for. The checks for that contract are in the prepaid PPA checklist.
