Solar & Battery Installation in Ontario, CA
Serving the Inland Empire from our Ontario office. Hot summers and high AC loads make solar-plus-battery especially valuable here.
What going solar looks like in Ontario
Ontario homes are served by Southern California Edison (SCE), and permits run through City of Ontario. 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.
