Solar & Battery Installation in San Diego, CA
From our La Jolla office, we serve San Diego County under SDG&E — the utility with some of the highest time-of-use rates in the country, which makes battery storage essential.

What going solar looks like in San Diego
San Diego homes are served by SDG&E, and permits run through City of San Diego. 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.
