Solar & Battery Installation in Santa Ana, CA
We design and install solar-plus-battery systems across Santa Ana, just minutes from our Irvine headquarters.
What going solar looks like in Santa Ana
Santa Ana homes are served by Southern California Edison (SCE), and permits run through City of Santa Ana. 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 Santa Ana
We design and install across Santa Ana — including Floral Park, French Park, Washington Square, Park Santiago, Fisher Park, and West Floral Park.
Climate & energy use
Santa Ana sits inland in central Orange County, so summers run noticeably hotter than the nearby coast and homes carry a real afternoon air-conditioning load, often pushed higher when the dry Santa Ana winds settle over the area. That cooling demand peaks late in the day as SCE's time-of-use rates climb, which is exactly when pairing solar with battery storage lets a home lean on stored energy instead of expensive grid power.
Roofs & housing stock
Santa Ana's housing stock ranges from early-1900s Craftsman bungalows and 1920s-30s period-revival homes in its historic districts to mid-century ranch houses and newer infill, so roofs here are a real mix of composition shingle, Spanish-style clay tile, and some low-slope sections. Clay tile and older framing call for careful mounting and flashing, so we tailor the racking and layout to each roof rather than using a one-size approach.
HOA & design review
Several of Santa Ana's historic neighborhoods, including Floral Park and French Park, fall under local historic-preservation review, and we handle the added documentation those designations require along with any HOA or neighborhood architectural submittals.

Battery backup & solar repair in Santa Ana
Yes — we handle more than new installs in Santa Ana. 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.
A battery added to an existing Santa Ana system does double duty: it stores your cheap daytime solar to use in the evening, and keeps essentials powered through outages. 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.
