The numbers behind going solar
Your electricity rate is the single biggest driver of whether solar pays off. We track it — honestly, monthly, in every state — and connect it to the calculators that turn it into a savings estimate. Built from U.S. Energy Information Administration (EIA), Electricity retail sales — average price by state.

Turn a rate into a savings estimate
What we measure: Average residential retail price of electricity published by the EIA for the state, in cents per kilowatt-hour — a statewide monthly average, not a personalized utility tariff or the rate any single household pays. EIA publishes state retail-price data on a lag of roughly two to three months; the latest period shown reflects that lag.
