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.
