Is Solar Worth It in Indiana?
The honest answer depends heavily on which utility serves you and how the system is sized — more so than in most states.
What changed the math for 2026
Two things affect Indiana more than many states: the loss of the 30% federal tax credit for homeowner-owned systems, and the 2022 shift away from full retail net metering toward the lower Excess Distributed Generation (EDG) rate for four of the five largest utilities. See Net Metering & EDG for the utility-by-utility detail.
What tends to make solar pencil out better here
- Being served by NIPSCO, whose feed-in tariff has generally paid more per kWh than the other four utilities’ EDG rate
- A system sized close to your actual usage, so less power is exported at the lower EDG rate
- Higher current electricity usage and bills
- A south- or west-facing roof with minimal shading
- Access to a competitive loan rate, or paying cash if that fits your finances
What tends to make it less favorable right now
- Being served by one of the four EDG utilities with a system oversized relative to usage
- Low current electricity usage/bills
- A roof needing replacement soon, or heavy shading
- Financing at a high interest rate that erodes the monthly savings
The honest way to find out
There’s no single answer that applies to every Indiana home — it’s a function of which utility serves you, your usage, your roof, and how you finance the system. The most reliable way to know is a specific, written proposal for your home that shows the real numbers using your utility’s actual current export rate, not a generic percentage-savings claim.
