Energy costs in Lafayette, LA
Energy prices are published by state, not by city, so the rates and bills below are Louisiana figures and apply to Lafayette the same as anywhere else in the state. The solar production is different: that is modelled for Lafayette's own coordinates, and it varies a lot within a single state.
Solar at Lafayette's coordinates
8,867kWh a year from 6 kW
That is close to the Louisiana average, so the state figure would not have misled you here. At 14.15¢ a kilowatt hour it pays back in about 9.4 years with full net metering.

Common questions
What is the electricity rate in Lafayette?
14.15¢ per kilowatt hour. That is the Louisiana residential average from the EIA — rates are published per state, not per city, so it applies across Lafayette and the rest of Louisiana alike.
What is the average electric bill in Lafayette?
About $156 a month for a typical Louisiana 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 Lafayette?
A 6 kW system at Lafayette's coordinates is modelled at about 8,867 kilowatt hours a year, which pays for itself in roughly 9.4 years at Louisiana electricity prices with full net metering. This one is genuinely local — production is modelled for this point, not the state.
