Solar & Battery Installation in Costa Mesa, CA
We install solar and battery across Costa Mesa — from Mesa Verde to the Eastside — on Southern California Edison, with permits run through the City of Costa Mesa, backed by our nearby Irvine crews for some of the fastest turnarounds in Orange County.
What going solar looks like in Costa Mesa
Costa Mesa homes are served by Southern California Edison (SCE), and permits run through City of Costa Mesa. 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.
