Solar + Powerwall 3 Expansion in Bakersfield

The completed Bakersfield project

OC Solar's completed-project record identifies this as a single-family residential solar-and-battery installation in Bakersfield. The verified design pairs an 18.49 kW array of 43 Qcells 430W modules with two Tesla Powerwall 3 units, two Powerwall 3 DC expansion packs, and a Tesla Backup Gateway on PG&E service.

The project passed final inspection on August 13, 2025, and received PG&E Permission to Operate on August 28, 2025. Customer name, street address, account information, financing, savings, and production estimates are intentionally excluded.

Why the solar and battery design work together

Bakersfield homes can carry substantial daytime cooling demand and continue using energy after solar production falls. This project combines a larger rooftop array with four storage components so available solar energy can be stored for later household use and configured backup loads.

Battery quantity alone does not determine backup duration. The practical result depends on the home's selected backup loads, household consumption, reserve settings, weather, and PG&E rate plan, so OC Solar sizes the complete solar-and-storage architecture around the individual property.

A tile-roof installation under City of Bakersfield review

The source record identifies a one-story concrete tile roof, the City of Bakersfield as the authority having jurisdiction, and PG&E as the utility. Those site and approval details affect array layout, attachment planning, equipment placement, permitting, inspection, and interconnection; they are part of the project design rather than a generic city-page assumption.
