For a Solana Beach household receiving Clean Energy Alliance generation service, keep both rate-identification numbers from your utility bill when preparing a solar-and-battery comparison. One identifies CEA generation pricing; the other identifies SDG&E delivery pricing. Neither is a solar production estimate or a PPA price.
That distinction gives your proposal preparer a clearer starting point. A qualifying no-upfront solar-plus-battery PPA can provide access to equipment without an outright purchase, but its value still depends on an accurate comparison with the electricity service you actually use.
Why are there two numbers?
CEA's rate-identification guide explains that a Rate Identification Number, or RIN, identifies an electric rate rather than an individual customer. It says CEA customers see separate generation and delivery RINs on their bills.
The guide links to California Energy Commission instructions for downloading hourly pricing information. It also cautions that the report does not replace the rates and pricing on your monthly statement. Use the current bill as a reference and ask the preparer to resolve any discrepancy before relying on the calculation.
Do not copy the sample numbers shown on an educational page into your proposal. Record the entries from your own statement, together with the bill date and named rate schedules.
Confirm the local utility arrangement
Solana Beach identifies CEA as its default power provider, with SDG&E delivering electricity and handling billing. Your actual statement matters because customers can choose different service arrangements.
If you previously opted out, do not assume a CEA-based comparison represents your present account. Our return-to-CEA guide explains why the service timeline should be confirmed separately from a solar proposal.
Give the proposal preparer a consistent record
Our suggested comparison checklist is:
- A recent complete bill, including generation and delivery details.
- Both rate identifiers and the statement's service-period dates.
- Household usage data for the period being modeled.
- The solar production and battery-operation assumptions.
- Any proposed rate or service change, clearly labeled with its expected timing.
For a hypothetical example, imagine two proposals use the same panels and battery but different electricity-price assumptions. Ask the providers to reconcile those assumptions before treating the difference as an equipment benefit. Keep household use, production, battery reserve and comparison period consistent where possible.
Have the preparer identify the applicable NEM or Solar Billing Plan treatment separately. A price identifier alone is not a complete calculation of imports, exports, fixed charges or the remaining utility bill. Request a written explanation of which charges the model includes and which remain outside it.
Keep battery operation and PPA payments visible
Ask how stored solar changes the timing of grid purchases, what energy remains reserved for outages and how conversion losses enter the model. A price comparison should use the proposed equipment's actual limits rather than assume unlimited shifting of daytime solar into evening hours.
General battery guidance explains that supported circuits, stored charge and household demand limit backup duration. Ordinary grid-tied solar alone generally cannot supply outage power; compatible backup equipment is required, and solar recharging depends on conditions.
The CPUC solar guide explains provider ownership and ongoing payments for solar electricity under a PPA. Review qualification, any upfront charges, rate, escalator, term, battery ownership and fees, maintenance and transfer provisions alongside remaining utility bills. No upfront purchase does not mean free electricity or guaranteed savings.
