Energy costs in Thornton, CO
Energy prices are published by state, not by city, so the rates and bills below are Colorado figures and apply to Thornton the same as anywhere else in the state. The solar production is different: that is modelled for Thornton's own coordinates, and it varies a lot within a single state.
Solar at Thornton's coordinates
9,573kWh a year from 6 kW
That is close to the Colorado average, so the state figure would not have misled you here. At 16.16¢ a kilowatt hour it pays back in about 7.7 years with full net metering.

16.16¢ per kilowatt hour. That is the Colorado residential average from the EIA — rates are published per state, not per city, so it applies across Thornton and the rest of Colorado alike.
What is the average electric bill in Thornton?
About $109 a month for a typical Colorado 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 Thornton?
A 6 kW system at Thornton's coordinates is modelled at about 9,573 kilowatt hours a year, which pays for itself in roughly 7.7 years at Colorado electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
