An SCE homeowner comparing solar-plus-battery PPAs should look beyond the total labeled “solar credits.” Different credits have different uses. Understanding those uses helps you see how solar can reduce electricity purchases while keeping the remaining utility bill in your budget.
The key question is: which credit is available, and which charge can it pay? Official guidance below was checked September 20, 2026.
Start with ordinary Energy Export Credits
For Solar Billing Plan customers, SCE’s billing FAQ explains that surplus electricity sent to the grid earns Energy Export Credits, or EECs, whose value varies hourly. These credits reduce eligible charges. They do not offset fixed fees, non-bypassable charges or taxes.
Non-bypassable charges are charges that ordinary export credits cannot cancel. That does not make every such charge a fixed monthly amount. Ask your proposal to identify the actual line items and calculation rather than grouping everything into a guessed minimum bill.
First confirm whether your account is on the Solar Billing Plan or an earlier NEM arrangement. A comparison using the wrong solar tariff can misstate the value of both exports and stored energy.
The Base Services Charge has a specific exception
SCE’s Base Services Charge FAQ for solar customers says residential solar customers pay this separate charge monthly, regardless of electricity usage. Ordinary generation does not offset it.
However, SCE expressly says a remaining Net Surplus Compensation credit or Energy Export Bonus Credits under the Solar Billing Plan can pay the charge. Those categories should be identified separately from ordinary EECs.
This is a reason to check your statement, not to assume every solar household has those credits. Ask SCE which balances are actually available on your account and how they were applied. A credit paying a charge also does not mean the underlying charge disappeared.
Keep three records separate
A useful proposal review includes:
- The projected SCE charges, ordinary export credits and any separately eligible credits.
- The expected solar-provider invoice and any separate battery payment.
- The assumptions supporting each credit, including eligibility and timing.
For a deliberately simplified example, assume a statement has a $20 service charge and $7 of qualifying credit that can pay it, with no other adjustments. The uncovered portion is $13. These are invented amounts to illustrate subtraction, not SCE rates or a forecast. Substituting $7 of ordinary export credit would not produce the same result for that charge.
For broader context, our SCE production and exports guide explains why rooftop generation, utility exports and PPA billing are different measurements.
Use a battery to manage energy purchases
SCE’s Solar Billing Plan overview describes using solar at home and storing energy for later use. A suitable battery can help reduce grid purchases during selected hours; it does not change the rules governing which credits pay which charges.
Ask the designer to account for charging losses, reserve settings and the electricity your household still imports. For outage planning, PG&E’s general battery guidance explains that available stored energy and household demand affect duration. Solar recharge requires usable sunlight and compatible backup equipment, so backup is finite.
Compare the complete PPA offer
A qualifying no-upfront solar-plus-battery PPA can provide access to equipment without an upfront purchase. The CPUC consumer guide explains that the provider owns the solar system and sells you its electricity. Ongoing payments still apply.
Review eligibility, the starting rate, any escalator, contract length, battery ownership and service coverage, and home-sale terms. Request a full-year comparison including remaining utility charges and all provider payments; no upfront purchase means neither free electricity nor guaranteed savings.
