What going solar looks like in Rancho Cucamonga
Rancho Cucamonga homes are served by Southern California Edison (SCE), and permits run through City of Rancho Cucamonga. 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.
