Solar by State

Prices, sun, system size and payback in every state.

How well solar pays off depends mostly on two numbers that change from state to state: what you pay for electricity and how much energy a kilowatt of panels produces where you live. Each state page brings together the official data for both, the electricity an average home uses, the system size that covers it and its payback range.

The data comes from the U.S. Energy Information Administration (average monthly use and bills, 2024), PVWatts from the National Laboratory of the Rockies (solar production) and Lawrence Berkeley National Laboratory (installed prices). Pick your state below.
