San Diego Community Power’s Solar Battery Savings program requires the participating battery to charge from on-site solar, not the grid. If a solar-plus-battery PPA quote includes this program’s incentives, ask the provider to make its charging assumptions consistent with that requirement before comparing projected costs.
This guide uses SDCP’s current program page and linked Fall 2025 manual, checked October 19, 2026. The 2024 pilot has separate resources; confirm the rules applicable to your enrollment.
Start with the program’s charging rule
The Solar Battery Savings eligibility page specifies solar charging and excludes grid charging. Section 2.2 of the program manual likewise requires charging from on-site solar and pairing the battery with an appropriately sized solar system.
A battery’s technical ability to charge from the grid does not establish permission to use that feature while enrolled. Ask the approved contractor how the proposed equipment will satisfy the program’s rule. Do not assume that a generic manufacturer operating mode or another homeowner’s settings apply to your enrollment.
Check the savings model for an incompatible assumption
Consider a hypothetical quote that counts SDCP incentives while also assuming the battery purchases low-priced grid electricity overnight for use the next evening. Those assumptions need to be reconciled before you rely on the total. This example does not assume a particular tariff, price or savings amount.
Our suggested review questions are:
- Does the forecast charge the battery only with the home’s solar production?
- How much solar energy remains for charging after daytime household use?
- How does the forecast handle cloudy periods and seasonal production changes?
- Who configures the charging controls, and who checks them after servicing or an equipment change?
- Which cost estimates change if an incompatible charging assumption is removed?
Ask for the revised assumptions in writing. A useful comparison should describe the operating plan that will actually be used, rather than combining benefits from different configurations.
If an app shows unexpected grid charging, record the time and displayed status and contact the contractor or manufacturer, with SDCP involved in program questions. Have them explain the cause and applicable requirements before changing controls based on a generic online tutorial.
Confirm the account and the rest of eligibility
SDCP serves San Diego, Chula Vista, Encinitas, Imperial Beach, La Mesa, National City and unincorporated San Diego County. Check actual enrollment on your statement. SDCP provides generation; SDG&E continues delivery, billing and grid outage response. SDCP’s bill explanation identifies the generation charges.
Solar charging is only one requirement. The program page also specifies residential service, a qualifying single-family service address and restrictions on other program participation. The approved contractor applies before installation. Confirm eligible equipment, funding reservation and the full terms; this article does not establish approval or available funds for your home.
Our approved-battery guide addresses model eligibility, while the overlapping-program guide covers a separate compatibility check.
Keep backup capability and PPA payments clear
The manual permits third-party-owned batteries, including PPA arrangements, with documented system-owner authorization. A qualifying no-upfront PPA can help eligible homeowners access solar and storage without purchasing the equipment upfront. Confirm who receives program incentives and how they affect the actual offer.
The CPUC solar guide explains provider ownership and ongoing payments for solar electricity. Review the rate, escalator, term, battery fees, maintenance, transfer provisions and remaining utility charges. No upfront purchase does not mean free electricity or guaranteed savings.
PG&E’s general battery guidance explains that available charge, supported circuits, demand and solar conditions limit backup duration. Ordinary grid-tied solar alone generally does not provide outage power. Solar recharging during an outage requires compatible backup equipment and suitable sunlight; a solar-only charging rule does not promise a full battery every evening.
Bring the proposed charging assumptions to a West Coast Alternatives consultation. WCA is independent of SDCP, and program eligibility must be confirmed through its official process.
