Solar Lease vs. PPA in California

Begin with the legal structure, not the monthly number

Under a lease, the provider generally owns the solar equipment and the homeowner pays for its use according to a scheduled payment. Under a power purchase agreement, or PPA, the provider generally owns the equipment and the homeowner buys the electricity it produces under the agreement's pricing method. The California Public Utilities Commission describes both as third-party-ownership arrangements, but it treats the payment distinction as fundamental.

A monthly invoice does not identify the agreement by itself. EnFin, for example, describes a levelized PPA that spreads an estimated annual energy payment across twelve months. That can resemble a lease bill even though it remains a PPA. Read the agreement title, ownership clause and payment formula. A proposal summary or salesperson's shorthand cannot change the signed contract.

Compare the complete payment schedule

For a lease, record the first payment, frequency, term and every scheduled increase. For a PPA, record the starting energy rate, the units billed, any annual escalator and whether payments use actual production or a levelized estimate. Include automatic-payment requirements, late fees, taxes or other charges identified in the documents. Ask for a year-by-year schedule instead of relying on the first-month figure.

An escalator compounds. As a neutral arithmetic example, a $200 monthly payment that rises 3% each year becomes $206 in year two and about $225.10 in year five. That is not an available All Star Solar offer or a prediction of utility rates. It simply shows why the starting figure and the lifetime schedule answer different questions. Compare any escalation with a no-escalator alternative when one is actually offered, using the same equipment and production assumptions.

Keep the utility bill in the comparison

Neither structure automatically eliminates the utility account. A grid-connected home can still import electricity, pay applicable fixed or minimum charges and receive export credits under the account's tariff. The CPUC's 2026 consumer guide warns against claims that a solar customer will never receive an electricity bill again. A responsible comparison adds the proposed lease or PPA payment to the modeled remaining utility cost.

Ask the proposal to show current annual consumption, estimated solar production, energy expected to be used directly, exports, grid imports and battery assumptions. The utility, rate plan, community-choice provider and interconnection status must match the property. A lower utility bill is not the same as a lower combined cost. Test a less optimistic scenario rather than treating every production estimate or future utility-rate assumption as guaranteed.

Read production promises and remedies precisely

A production guarantee should identify the approved estimate, measurement period, exclusions and remedy. Determine whether the provider measures one year at a time or averages a longer period, how outages or customer-caused conditions are treated, and how a shortfall payment is calculated. A guarantee of solar production does not necessarily reimburse every utility charge or guarantee a household's savings.

A lease and a PPA may include different production protections. EnFin's homeowner information, for example, tells customers to distinguish its lease from its PPA and to check the specific agreement. Do not transfer a benefit described for one product onto another. Keep the proposal, final design, production estimate and agreement together so the guaranteed figure can be compared with the system that was actually installed.

Identify who owns, monitors and repairs the system

In both common third-party structures, the provider owns the system. Ownership affects who may receive ownership-based incentives, who carries specified service responsibilities and what happens at transfer or the end of the term. The homeowner still has obligations. The agreement may address access, insurance, vegetation, roof work, internet connectivity, equipment damage and notification of a property sale.

Separate manufacturer warranties, installation workmanship, monitoring and the provider's contractual service promise. They can involve different parties and exclusions. Ask which phone number handles a production concern, a roof concern, battery behavior and an urgent electrical issue. Confirm whether labor, removal and reinstallation, shipping or roof repairs are covered. General language such as “maintenance included” is not enough to establish every cost.

Review battery and backup claims separately

If the proposal includes a battery, record the exact model, usable capacity, continuous output, reserve setting and circuits planned for backup. Battery storage can shift some solar energy to later hours, but it cannot make an unlimited load or outage promise. A higher backup reserve may leave less capacity for daily bill management. Actual results depend on production, household demand, operating settings and equipment limits.

Check who controls software settings and whether participation in a grid program is optional or required. Read the battery warranty alongside the lease or PPA. Ask how a failed battery, communications outage or replacement is handled and whether solar production continues. The phrase “solar plus battery” does not establish whole-home backup, duration, availability during every outage or a particular bill result.

Plan for a sale or refinance before signing

The CPUC and Contractors State License Board both tell homeowners to study transfer, buyout and early-termination provisions. A future buyer may need to qualify and agree to an assignment. Other possible paths may include prepayment or purchase, depending on the contract. Those actions are not interchangeable, and the price or process can change over time. Do not assume a buyer will automatically accept the obligation.

Find the required notice period, provider contact, transfer documents, qualification rules and fees. Ask what happens if the buyer declines or cannot qualify. If a move is plausible, compare the agreement at the expected sale year rather than only at year one. Before listing, obtain current transfer instructions from the provider and involve the real-estate and escrow professionals handling the transaction.

Understand end-of-term and early-exit choices

Read what happens when the scheduled term ends. The contract may describe renewal, removal, continued operation, purchase or another path, but available options and pricing depend on the agreement. Ask who pays for removal and roof restoration, how purchase value is determined, and what happens if the equipment is still operating. Do not infer a free transfer of ownership unless the document says so.

Also locate the consequences of an early exit, default, casualty, condemnation, reroof or major home alteration. A quoted buyout is not necessarily the same as prepaying future obligations. Ask for examples tied to the actual contract, then confirm the governing language. A homeowner expecting to remodel, replace a roof or move within the term should give these provisions as much attention as the opening payment.

Use California's required disclosures as a checkpoint

California's solar consumer materials are meant to slow the decision down and expose financial and project details. The CPUC says residential solar customers in covered investor-owned utility territories must receive and acknowledge the current Solar Consumer Protection Guide for qualifying interconnection applications. CSLB also describes solar disclosure-document requirements and advises consumers to put equipment, costs, promises and contractor responsibilities in writing.

Read every disclosure before signing and compare it with the proposal and agreement. Check names, equipment, system size, battery, payment schedule, assumptions, contractor role and cancellation instructions. If the oral presentation was mainly in another language, review the applicable language requirements and obtain documents you can understand. Do not sign blank fields or allow urgency about a promotion to replace a complete review.

Compare lease, PPA and ownership with one worksheet

Create rows for system owner, upfront payment, year-one payment, annual increases, term, total scheduled payments, estimated remaining utility cost, production remedy, monitoring, repairs, insurance duties, roof work, transfer, early exit and end-of-term choices. Use the same solar size, battery configuration, production estimate and utility assumptions across offers. Add exclusions such as panel upgrades or roofing instead of pretending every scope is equal.

Include a cash or loan ownership option when it is genuinely available. The U.S. Department of Energy notes that purchased systems can have a lower total cost than loan, lease or PPA arrangements, but cash flow, service preferences and household circumstances differ. The best structure cannot be declared from a generic table. It is the one whose documented costs, responsibilities and risks fit the homeowner after all options use comparable inputs.

Bring the controlling documents to the review

For a useful comparison, bring the latest electric bill, twelve months of usage when available, both proposals, the full agreements, payment schedules, production estimates, equipment lists and warranty documents. Mark every number that came from a contract and every number that remains an assumption. Keep screenshots or advertisements only as supporting context; they do not replace the final documents.
