Solar & Battery Installation in Fullerton, CA
North Orange County's Fullerton — home to Cal State Fullerton and a mix of mature mid-century and hillside neighborhoods — is a quick run from our Irvine headquarters for in-house solar, battery, Tesla Solar Roof, and HVAC.
What going solar looks like in Fullerton
Fullerton homes are served by Southern California Edison (SCE), and permits run through City of Fullerton. We manage both for you. Under NEM 3.0, the smart play here is solar sized to charge a battery, so you run your home on stored solar during the expensive evening peak instead of buying power at top rates.

Solar designed around Fullerton
We design and install across Fullerton — including Sunny Hills, Raymond Hills, and Amerige Heights.
Climate & energy use
Fullerton sits inland in north Orange County, so summers tend to run hotter and drier than along the coast, which drives a meaningful afternoon and early-evening cooling load. The hillier northern and eastern parts of the city can see Santa Ana wind events and elevated fire exposure, which is part of why SCE may call Public Safety Power Shutoffs in higher-risk areas — making a paired battery worth sizing to carry essentials and AC through an outage.
Roofs & housing stock
Much of Fullerton's housing is mature mid-century ranch and tract housing with low-slope, composition-shingle roofs, mixed with Spanish and Mediterranean homes carrying clay or concrete barrel tile and newer two-story homes up in the hillside tracts. Tile roofs call for tile-specific flashing and hook mounts and a roof condition check before install, while older shingle roofs are often a good moment to coordinate solar with a re-roof so the array isn't pulled twice.
HOA & design review
Master-planned and hillside communities such as Amerige Heights often carry HOA architectural-review requirements, and we prepare and submit those approval packages alongside the City of Fullerton permit.

Battery backup & solar repair in Fullerton
Yes — we handle more than new installs in Fullerton. Our in-house crews add battery backup to existing solar systems, diagnose and repair arrays regardless of who installed them, and remove and reinstall panels when a roof needs replacing.
The Public Safety Power Shutoff exposure noted above is exactly what backup batteries answer — stored solar keeps your Fullerton home's essentials running when the grid goes dark. And if a re-roof is coming, the tile roofs described in the notes above are why panel removal and reinstallation here is careful, flashing-first work — we detach, store, and reset your system and bring it back online.
