A qualifying no-upfront solar-plus-battery PPA can help an SCE homeowner start using renewable energy while preserving cash. Later, a household may want to make a larger payment or explore owning the equipment. Those choices need different questions.
Before accepting a quote described as a “payoff,” ask whether it prepays electricity, purchases equipment or does something else under the agreement. Official sources were checked September 15, 2026; your provider’s written terms determine the options available.
What does prepayment change?
Prepayment concerns when you pay for contractual service or energy. It does not automatically transfer ownership of the panels or battery.
For example, Sunrun’s explanation of leases and PPAs, updated July 10, 2026, describes prepaid arrangements that retain third-party ownership while changing the payment schedule. This illustrates the distinction; it is not a claim that every provider offers the same option or that a particular WCA proposal includes it.
Ask for an itemized prepayment quote showing the covered period, which future charges it replaces and any payments that remain. Have the provider confirm whether maintenance, warranties, production commitments and home-sale requirements continue under the existing agreement or an amendment.
A useful written answer says both what you have paid for and who still owns each component.
What does an equipment purchase change?
Check availability before requesting either change: Sunrun’s FAQ says switching to a prepaid structure must occur before installation, while equipment purchases afterward are limited to contractual windows. Other agreements require their own review.
A purchase option concerns ownership. Sunrun’s customer FAQ says moving from a lease or PPA to a purchase depends on timing rules. Do not assume you can buy the system at any moment or simply add up the remaining invoices to calculate its price.
Request the applicable contract clause, available purchase date, price calculation, quote expiration and list of equipment included. Ask for documentation confirming when ownership transfers and which service obligations or warranties survive the transaction.
If you are comparing prepayment and purchase quotes, put those details side by side. A smaller payment alone does not establish the better fit when the two choices deliver different ownership and service arrangements.
Keep SCE charges in the comparison
SCE’s Solar Billing Plan FAQ explains that charges and export credits are calculated monthly, with an annual settlement at the end of the Relevant Period. Some charges cannot be offset by export credits.
Paying the private solar provider does not prepay your SCE account. Ask for the remaining utility costs under your applicable tariff alongside each contract option. Existing NEM customers should have their own billing arrangement identified.

Account for the battery explicitly
Have each quote name the battery, inverter and backup controls. Confirm who owns them afterward, who handles repairs and what replacement coverage remains. A solar payment description alone cannot establish the storage terms.
The equipment’s physical limits still matter. PG&E’s general battery guidance explains how available charge and supported loads affect backup duration. Those principles also apply to an SCE home: changing payment terms does not add capacity, and outage recharging requires suitable sunlight and compatible equipment.
Review future flexibility before signing
The CPUC’s consumer guide explains PPA ownership, generated-electricity payments and questions about upfront amounts, escalators, early termination and home sales. Review these provisions even when starting with no upfront payment.
Confirm qualification, all installation and battery charges, the rate, term and continuing obligations. No upfront purchase means neither free electricity nor guaranteed savings.
