Energy costs in Fullerton, CA
Energy prices are published by state, not by city, so the rates and bills below are California figures and apply to Fullerton the same as anywhere else in the state. The solar production is different: that is modelled for Fullerton's own coordinates, and it varies a lot within a single state.
Solar at Fullerton's coordinates
10,007kWh a year from 6 kW
That is close to the California average, so the state figure would not have misled you here. At 33.25¢ a kilowatt hour it pays back in about 3.7 years with full net metering.

Common questions
What is the electricity rate in Fullerton?
33.25¢ per kilowatt hour. That is the California residential average from the EIA — rates are published per state, not per city, so it applies across Fullerton and the rest of California alike.
What is the average electric bill in Fullerton?
About $160 a month for a typical California household. Again this is a state figure: EIA reports revenue and customer counts by state, so a city-level bill would be an invention.
Is solar worth it in Fullerton?
A 6 kW system at Fullerton's coordinates is modelled at about 10,007 kilowatt hours a year, which pays for itself in roughly 3.7 years at California electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
