Energy costs in Knoxville, TN
Energy prices are published by state, not by city, so the rates and bills below are Tennessee figures and apply to Knoxville the same as anywhere else in the state. The solar production is different: that is modelled for Knoxville's own coordinates, and it varies a lot within a single state.
Solar at Knoxville's coordinates
8,071kWh a year from 6 kW
That is close to the Tennessee average, so the state figure would not have misled you here. At 14.47¢ a kilowatt hour it pays back in about 10.1 years with full net metering.

Common questions
What is the electricity rate in Knoxville?
14.47¢ per kilowatt hour. That is the Tennessee residential average from the EIA — rates are published per state, not per city, so it applies across Knoxville and the rest of Tennessee alike.
What is the average electric bill in Knoxville?
About $162 a month for a typical Tennessee 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 Knoxville?
A 6 kW system at Knoxville's coordinates is modelled at about 8,071 kilowatt hours a year, which pays for itself in roughly 10.1 years at Tennessee electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
