If the equipment or installation scope changes after you choose a solar-plus-battery PPA for an SCE-served home, ask for the revised work and payment terms in writing before approving it. A useful upgrade can still fit a qualifying no-upfront offer, but the revised documents should show whether that is actually the case.
This guide uses primary sources checked October 19, 2026. It focuses on documenting a project change, rather than assuming that a verbal description such as “included upgrade” explains every cost.
Identify which agreement is changing
The CPUC solar guide explains that a PPA provider owns the solar system and sells its electricity over the agreed term. Your project may also involve installation documents and a contractor responsible for the physical work.
Ask the provider to identify which documents need revision and who must approve them. Do not assume that a contractor’s equipment note also changes the PPA’s energy rate, or that a PPA amendment automatically updates the installation scope.
For home improvement contracts, CSLB’s contract guidance says changes to price or scope must be documented in a written change order signed by the customer and contractor before the change. It also recommends recording verbal promises in the agreement. Ask the project team how the applicable installation paperwork and PPA documents will be coordinated.
Compare the offer before and after the change
Our suggested comparison separates the equipment from its payment treatment:
- What exact equipment or work is being added, removed or substituted?
- Does any amount become payable upfront?
- Does the energy rate, escalator, contract length or separate battery payment change?
- Who owns and maintains the revised equipment?
- Does the completion schedule or backup-circuit plan change?
For example, suppose a hypothetical provider proposes different battery equipment and says the project still requires no upfront payment. Ask for the revised ongoing charges too. An unchanged upfront amount does not establish that the lifetime payment terms are unchanged. Conversely, a documented substitution may leave the agreed payments intact; read the actual revision instead of assuming either outcome.
Keep the accepted revision with the original proposal so the household and service team can identify the final arrangement.
Keep SCE approval separate from the commercial agreement
SCE’s interconnection page describes the process for connecting generating equipment to its system and lists a dedicated Net Energy Metering/Solar Billing Plan team. Ask your installer whether the proposed change requires revised utility documents, permit plans or another approval before operation.
A signed price or equipment revision is not itself SCE permission to operate. For unresolved NEM or Solar Billing Plan interconnection questions, SCE lists Customer.Generation@sce.com and 866-600-6290. Have the project number and proposed equipment details available.
Our guide to adding storage to existing SCE solar covers the separate compatibility questions for an already operating system.
Reconfirm the backup result
If equipment changes, request an updated explanation of supported circuits and simultaneous loads. PG&E’s general battery guidance explains that stored energy, household demand and available solar affect backup duration. Those technical limits also matter for SCE homes.
Ordinary grid-tied solar alone generally does not supply outage power. Outage recharging needs suitable sunlight and compatible backup equipment; a revised equipment list does not promise unlimited runtime.
A suitable PPA can help eligible homeowners obtain solar and included storage while preserving cash upfront. Confirm qualification, ongoing payments, maintenance, transfer provisions and remaining utility charges. No upfront purchase does not mean free electricity or guaranteed savings.
Bring the original offer and proposed revision to a West Coast Alternatives consultation to organize the questions that need answers before the project moves forward.
