Energy costs in Fairfield, CA
Energy prices are published by state, not by city, so the rates and bills below are California figures and apply to Fairfield the same as anywhere else in the state. The solar production is different: that is modelled for Fairfield's own coordinates, and it varies a lot within a single state.
Solar at Fairfield's coordinates
9,857kWh 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 3.8 years with full net metering.

Common questions
What is the electricity rate in Fairfield?
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 Fairfield and the rest of California alike.
What is the average electric bill in Fairfield?
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 Fairfield?
A 6 kW system at Fairfield's coordinates is modelled at about 9,857 kilowatt hours a year, which pays for itself in roughly 3.8 years at California electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
