An SDG&E homeowner considering a new solar-plus-battery PPA may see EV-TOU-5 in the proposal despite having no electric car. That can be correct: SDG&E identifies EV-TOU-5 as the residential Solar Billing Plan rate. The name alone does not mean you need to buy an EV before exploring solar.
A qualifying no-upfront PPA can provide access to solar without purchasing the equipment outright. Start by matching the proposal to your actual utility account and household demand. This guidance was checked September 23, 2026.
Why does a solar home use an EV-named rate?
SDG&E's Solar Billing Plan overview states that residential customers on that plan use EV-TOU-5. Its pricing-plan chooser describes EV-TOU-5 as designed for customers charging EVs at home and/or customers on the Solar Billing Plan.
For a residential Solar Billing Plan household, EV ownership therefore is not a prerequisite implied by the rate's name. This does not establish eligibility for every other EV rate, a private PPA or a particular installation.
Ask the proposal to show both the solar billing arrangement and the electricity rate. Existing NEM customers should confirm their own account treatment with SDG&E before assuming a new-system illustration applies to them.
Check the complete rate name
EV-TOU-5 and EV-TOU are different plans. SDG&E describes EV-TOU as a separate-meter arrangement for tracking vehicle electricity use independently. Seeing EV-TOU-5 in a solar proposal is not, by itself, a requirement to install a dedicated vehicle meter.
The chooser also lists EV-TOU-5-P, which includes event-day pricing. Have the preparer identify the exact schedule used in the forecast rather than labeling it simply an “EV rate.”
Our recommendation is to request a no-EV base case if you do not currently charge a vehicle. If a purchase is planned, request a second scenario with clearly stated charging demand and timing. Do not quietly add hypothetical driving loads to the household's current bill comparison.
Let battery planning follow your daily routine
SDG&E identifies 4–9 p.m. as on-peak hours. Stored solar can help supply evening household loads even when no car is plugged in. Ask the installer to model your actual evening cooking, cooling and other usage, battery losses and the charge held for outages.
For example, a household planning an EV next year can compare today's evening appliance demand with a separate future charging scenario. These are planning scenarios, not a promise that one battery will cover both.
PG&E's general battery guidance explains that backup duration depends on available charge and connected loads. Specify supported circuits and power limits; solar recharge requires suitable sunlight and compatible equipment. Rate enrollment does not create outage capability.
Keep the complete payment picture
SDG&E's Base Services Charge guidance says this charge replaces the former fixed monthly service fee on EV-TOU-5. Avoid counting both. Use current account-specific charges and your generation provider's pricing in the comparison. Our Community Power and SDG&E bill guide explains those separate roles.
The CPUC solar consumer guide explains that a PPA provider owns the solar system and sells its production to the homeowner. Confirm zero-upfront eligibility, ongoing rate, escalator, term, installation charges, maintenance and home-sale terms. Document battery inclusion, ownership and replacement coverage.
