Roof-First Design and In-House Permitting

OC Solar models a custom layout against the home’s roof and electricity use, then prepares and submits the building permit and utility interconnection paperwork in-house, including the application for Permission to Operate. After a contract is signed, a named project manager is assigned and the company says it reports status weekly through inspection and utility approval.

Solar and Battery Systems Built to Work Together

The company installs rooftop panels from Tesla, Q CELLS, and REC, typically paired with Enphase or SolarEdge inverters and, where storage is part of the job, a Tesla Powerwall 3 or Enphase IQ Battery. As a Tesla Powerwall Premier Certified installer, it sizes batteries so midday production can be used in the evening and so essential loads can keep running if the grid goes down, and it will review an existing system’s equipment, roof, and utility agreement before adding panels or storage.

The Roof and the Array Under One License

Because OC Solar holds both general building and electrical classifications on license 1023627, it can plan a new or replacement roof with the solar array instead of splitting the work between trades. The company installs Owens Corning shingle re-roofs as an Owens Corning Roofing Preferred Contractor and Tesla Solar Roof systems as a Tesla Solar Roof Premier Certified installer, and the same crews can detach an existing array, replace the roof underneath it, remount the panels, and verify production.

Service for Systems Another Installer Left Behind

OC Solar diagnoses and repairs systems it installed and systems it did not, including work left unfinished or abandoned by another company. The service team works across major panel, inverter, and battery brands and provides a written scope before repair work begins.

Level 2 Charging on Their Electrical License

Under its C-10 electrical classification, OC Solar installs home Level 2 chargers, including the Tesla Wall Connector and universal chargers that use the standard J1772 connector. The company runs a load calculation on the electrical panel first and can wire the charger to work with a home’s solar or battery system rather than treating it as a separate electrical job.

• A Regional Installer, Not a National One
• Another Company’s Workmanship Warranty Does Not Carry Over
• City and Utility Timelines Are Outside Their Control

A Regional Installer, Not a National One

OC Solar serves homeowners in Orange, Los Angeles, Riverside, San Bernardino, Ventura, and San Diego counties, and it also lists coverage in Fresno and Kern counties, with headquarters in Irvine. It is not a nationwide installer, the online site-audit calendar is limited to eligible Southern California addresses, and anyone outside the published footprint should confirm coverage for their address.

Another Company’s Workmanship Warranty Does Not Carry Over

When OC Solar services a system installed by someone else, it cannot honor that installer’s workmanship warranty. Manufacturer warranties on existing equipment still follow the manufacturer’s terms, and the company says it will explain what is and is not covered before any repair begins.

City and Utility Timelines Are Outside Their Control

OC Solar handles permitting, inspections, interconnection, and Permission to Operate paperwork, but it states that those queues are set by the city and the utility, including Southern California Edison, San Diego Gas & Electric, Pacific Gas & Electric, or a municipal utility. A homeowner should expect the calendar after a signed contract to depend in part on those outside offices, not only on the installation crew.
