San Diego Community Power customers comparing solar-plus-battery proposals should check the exact battery model against the Solar Battery Savings approved-product list. A familiar manufacturer name is only the starting point: the listed model, expansion equipment and attached conditions matter to the incentive calculation.
This guide uses SDCP’s current program page and its linked June 8, 2026 equipment list, checked October 17, 2026. The 2024 pilot has separate resources. Confirm the rules applicable to your application before relying on a quoted rebate.
Start with your account and proposed equipment
SDCP’s service overview lists San Diego, Chula Vista, Encinitas, Imperial Beach, La Mesa, National City and unincorporated San Diego County. Confirm your actual enrollment; a San Diego County address alone does not establish eligibility.
Community Power supplies generation, while SDG&E handles delivery, billing and grid outages. The bill guide helps identify the generation charges on your SDG&E statement. Neither that statement nor a private PPA proposal is an equipment approval.
The program manual, section 2.4, says only approved batteries qualify for participation and incentives. The qualified-product list and contractor portal are updated as equipment is accepted. Ask your contractor to identify the precise model and configuration being submitted.
Read the expansion-unit footnotes
The approved battery list includes model names, nameplate usable capacity and whether manufacturer terms are required. Its expansion-equipment footnotes are particularly useful when comparing a larger-storage proposal:
- Tesla Expansion Packs receive 50% of the applicable incentive rate, with a maximum of two per Powerwall under the listed conditions. They must accompany a new Powerwall installation; adding them to an existing Powerwall is not incentivized.
- Lunar LE-DC-UNIT expansion units have the same 50% rate treatment, with a maximum of two per L2-ESS-20KWH. They must accompany a new L2-ESS-20KWH installation rather than expand an existing one.
The list explains that these additions increase usable energy capacity without increasing power output. These are program conditions, not a recommendation to install the maximum quantity or a promise of project approval.
Compare the quote line by line
Consider two hypothetical proposals: one installs a new main battery with an expansion unit, while another adds expansion equipment to a battery already installed. Do not carry the first proposal’s incentive assumption into the second simply because the expansion hardware has the same name.
Our suggested review checklist is:
- Match the complete model names and quantities in the quote to the application.
- Identify which equipment is new and which is already installed.
- Ask for a separate incentive calculation for each equipment type.
- Confirm any required manufacturer terms and who completes them.
- Request a revised cost comparison if the equipment changes.
The Solar Battery Savings page directs customers to approved contractors, who apply before installation. Confirm residential service, the qualifying single-family address, solar-only charging, other enrollment restrictions and funding reservation. Equipment appearing on the list does not reserve funding. Our rebate-cap guide explains a separate limit on the total incentive.
Keep useful backup and PPA terms in view
More stored energy can support longer operation under suitable conditions, but it does not automatically support a larger simultaneous load. PG&E’s general battery guidance explains designated backup circuits and the effects of energy use, reserve and solar conditions on duration. Ask for a supported-load list; ordinary grid-tied solar alone generally does not provide outage power.
A qualifying no-upfront solar-plus-battery PPA can help eligible homeowners access equipment without an upfront purchase. SDCP’s manual allows third-party-owned batteries with documented owner authorization. Verify that authorization and the actual offer rather than assuming every PPA qualifies.
The CPUC solar guide explains provider ownership and ongoing electricity payments. Review the rate, escalator, term, battery fees, maintenance, transfer provisions and remaining utility costs. No upfront purchase does not mean free electricity or guaranteed savings.
Bring the complete equipment schedule to a West Coast Alternatives consultation. WCA’s independent consultation does not establish SDCP approval or endorsement.
