How to read this guide

GridPermit collects California residential solar and permitting facts directly from official sources (city, county, and state government sites, utilities, and public utilities commissions) and shows only what we can verify, with a confidence score and a link to where it came from. Nothing here is estimated or inferred beyond what's stated below. See our methodology for the rules this page follows.

Battery/solar incentive program on record

California SGIP - current category and budget check required

New applications and waitlist applications for ratepayer-funded SGIP budgets closed on December 30, 2025. New AB 209 applications have a June 30, 2028 deadline. The 2026 SGIP rate table publishes $3.10/W for solar and $1.10/Wh for storage in applicable Residential Solar and Storage Equity categories. Household eligibility and live budget availability vary by category and program administrator; check the official Program Metrics tracker before relying on an incentive.

Status on file: unknown. Verify current status before relying on this.

Permit fees

The page states SolarAPP+ charges its own processing fee and city fees are payable through the OPC, and that the first 3 revisions submitted through SolarAPP+ are free, but no specific dollar figure for the city's own permit fee was stated. Some supporting official material could not be independently confirmed from the full source in GridPermit's latest review. Verify the current requirement with the authority before relying on it.

Utility and generation supplier

Utility

Southern California Edison (SCE)

SCE's own 'Incorporated Cities and Counties Served by SCE' fact sheet (updated 3/17/2025) explicitly lists 'Rialto' by name among the cities in its service area.

Confidence: High (0.9)

Source(s): Incorporated Cities and Counties Served by SCE

Generation supplier

Southern California Edison (SCE) (utility)

Western Community Energy (WCE), the only CCA ever formed to serve inland Southern California, deregistered with the CPUC and dissolved via Chapter 9 bankruptcy in 2021. Its own now-stale website (frozen since its original 2020 launch announcement) confirms its service area was limited to only six Riverside County cities (Norco, Perris, Wildomar, Jurupa Valley, Hemet, Eastvale) and never included any San Bernardino County city. No other CCA was found serving San Bernardino County in this dataset's research. SCE is recorded as both the distribution and generation utility.
