San Marcos homeowners exploring solar and battery backup may encounter Clean Energy Alliance's Solar Plus program alongside a separate provider's power purchase agreement, or PPA. Both can make equipment accessible without buying it outright, when the household and property qualify. Comparing the written payment and service terms helps you choose a suitable arrangement.
This guide reviews official sources checked September 18, 2026. It does not establish eligibility for a particular home or identify West Coast Alternatives as a Solar Plus certified partner.
Check your San Marcos electricity account first
CEA's current FAQ lists San Marcos among its member cities. CEA supplies electricity generation service; SDG&E handles delivery, billing and grid outages. Check the generation section of your statement to confirm your actual enrollment before asking about a CEA program.
Receiving CEA electricity is different from having rooftop equipment installed. Solar Plus requires a separate project and agreement. Ask the program team about current availability and property requirements, particularly if you already have solar or storage.
What does Solar Plus advertise?
CEA's Solar Plus page advertises solar panels and batteries with no upfront costs or credit check. It identifies a fund as the system owner and describes a design process based on household electricity use and available roof space.
That can be an appealing route to generation and storage while preserving cash. The offer still involves paying for energy. The program flyer linked by CEA says customers pay for system generation on their bill and describes a 25-year rate arrangement with a 1.9% escalator.
Request the actual starting rate, when and how the escalator applies, payment calculation and remaining utility charges in a dated proposal. A predictable rate schedule is not a flat lifetime payment or a guarantee of savings; CEA also states that its advertised savings are estimates.
Compare a separate PPA using the same questions
The CPUC consumer guide explains that a PPA provider owns the solar system and sells its generated electricity. A qualifying no-upfront solar-plus-battery PPA can offer a similar cash-preservation benefit, but its contract may use different pricing, equipment and service terms.
Ask each proposal to identify:
- Who owns the panels and battery, and who installs and services them.
- All upfront charges, ongoing energy payments and any separate battery fee.
- The rate schedule, contract length, home-sale process and purchase or exit provisions.
- The equipment, electrical work and backup circuits included in the price.
Use the same household usage and future-load assumptions in both comparisons. Include the remaining SDG&E and generation-provider charges rather than comparing only the solar payment. Our SDG&E solar-offset guide explains why annual generation matching annual use does not itself produce a zero bill.
Read service coverage alongside backup capability
CEA's linked flyer includes system service and battery replacements, with exclusions for customer-caused damage or issues; shade management and panel cleaning are not included in maintenance. Have the program team show how those provisions appear in your agreement. Request the corresponding coverage and exclusions from any separate PPA provider.
For either option, ask for supported loads, battery capacity, operating controls and a realistic outage estimate. PG&E's general battery guidance explains that backup duration depends on stored energy, connected demand and solar availability. Solar recharge needs usable sunlight and compatible backup equipment; storage cannot guarantee uninterrupted power through every outage.
Bring your San Marcos bill, backup priorities and written proposals to the West Coast Alternatives homeowner journey. Direct Solar Plus enrollment and program-specific eligibility questions to CEA's listed program contacts. Clear ongoing costs and equipment terms make the benefits of either suitable offer easier to evaluate.
