IndianaSolar Incentives 2026: Tax Credits, Rebates & Net Metering

Indiana does not offer a state income tax credit specifically for residential solar. Most homeowners rely on the 30% federal Residential Clean Energy Credit as the primary up-front incentive.

Indiana does not have a statewide retail-rate net metering mandate. Most utilities offer some form of buyback program at avoided-cost rates, which typically value exported solar at 25-50% of the retail rate.

For IN homeowners, this often makes battery storage more attractive — keeping your generation onsite and consuming it directly avoids the unfavorable export rate. Top utilities: Duke Energy IN, AEP, NIPSCO.

Indiana credits exported solar at roughly ~25–50% of retail of the retail rate. See full Indiananet metering rates & rollover rules →

Solar installs in Indiana average $2.90 per watt in 2026. A typical 8 kW system runs about $23,200 before incentives. After the 30% federal credit, the net cost drops to roughly $16,240 — the real number most IN homeowners pay.

Your price moves with system size, roof complexity, and equipment tier. Run the Indiana savings calculator for a number matched to your actual electricity bill.

No — there is no government program handing out free solar in Indiana. “Free solar” and “no-cost solar program” ads are leases or power purchase agreements (PPAs): a company owns the panels, claims the 30% federal credit for itself, and bills you for the power.

Buying your system — with the incentives in your name — almost always wins on lifetime savings. Read the full breakdown of “free solar” offers →

3 major utilities operate in Indiana: Duke Energy IN, AEP, NIPSCO. Specific rebate availability varies year to year and is typically distributed first-come, first-served until annual budget caps are reached.

Before scheduling any installation, verify current rebate status directly with your utility — programs open and close throughout the year. Most Indiana installers will pull up-to-date rebate data during a site assessment.

Indiana does not currently offer a property tax exemption for solar. The added home value from a solar installation is generally included in the next assessment cycle.

Indiana does not exempt solar equipment from sales tax, so installation invoices include standard sales tax on hardware components.
