Solar + Powerwall in Temecula

The completed Temecula project

OC Solar's completed-project record identifies this as a single-family residential solar-and-battery installation at a Temecula address. The verified design pairs an 8.10 kW array of 20 Qcells 405W modules with a Tesla Powerwall 3, one expansion unit, and a Tesla Backup Switch on Southern California Edison service.

The installation was completed on February 2, 2026, passed final inspection on March 5, 2026, and received SCE Permission to Operate on March 13, 2026. Customer name, street address, account information, financing, savings, and production estimates are intentionally excluded.

Solar generation with expanded home storage

The Powerwall 3 provides the system's integrated inverter and base storage, while the recorded expansion unit adds storage capacity without creating a second independent inverter. That pairing can retain more available solar energy for later household use or configured backup loads, although actual backup duration depends on consumption, reserve settings, weather, and the selected loads.

A two-story tile-roof project permitted through Riverside County

The source record identifies a two-story concrete tile roof and Riverside County as the authority having jurisdiction. That distinction matters: a Temecula mailing address can fall outside the City of Temecula's permitting boundary, so OC Solar confirms the actual jurisdiction before preparing the attachment plan, permit package, inspection path, and SCE interconnection paperwork.
