About solar in Indiana

Indiana solar is booming. The state deployed nearly 3 gigawatts of new solar in 2025 — almost double the year before — bringing the total past 7 gigawatts, and forecasters expect another 13 gigawatts over the next five years, one of the fastest build-outs in the country. Most of that is large solar farms, but the same sunshine and falling equipment costs are at work on Indiana rooftops.
Indiana has no state solar tax credit, and retail-rate net metering has been replaced by Excess Distributed Generation net billing: power you use the moment it is made offsets your bill one-for-one, while power exported to the grid is credited at 1.25 times the wholesale locational price — and unused credits roll over from month to month with no expiration. That math rewards right-sized systems and using your own power, so an installer's load analysis matters more here than in most states. Check the current Indiana rebates and incentives for your utility's exact tariff — AES Indiana, Duke Energy Indiana, NIPSCO, Indiana Michigan Power, and CenterPoint each run their own version.
The companies below install solar across Indiana. Ask each one how much of your production your home would actually use, and whether a battery changes the math, and see our solar energy resources for guides to net billing, storage, and reading a quote.
