Indiana solar incentives in 2026
Last updated · every IN program below is verifiable against the sources at the foot of this page.
The most valuable solar incentive in Indiana right now is Sales and property tax exemptions. Overall, the state's incentive stack rates as limited compared with the rest of the country.
The federal credit is gone — start here
The 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025. If you are buying a system in Indiana this year, there is no federal credit. That is a roughly $7,680 swing on an $25,600 system compared with 2025 pricing, and it is why state programs matter more now than they did a year ago.

Indiana solar tax credit
There is no Indiana solar tax credit in 2026, and no federal one either — Section 25D ended for systems installed after December 31, 2025. What Indiana does offer on the tax side is sales and property tax exemptions, covered below.
Indiana solar rebates and grants
Indiana runs no statewide solar rebate or grant program in 2026. Individual utilities and municipalities sometimes do, and those are rarely advertised well — ask your utility directly what they pay toward a residential install.
Indiana offers property and sales tax exemptions for solar but no state tax credit or rebate.
Net metering and export rates in Indiana
Indiana phased out retail net metering for new customers in 2022. Investor-owned utilities now credit exports at roughly 1.25× wholesale (an "excess distributed generation" rate), well below retail.
Compare this with net metering in every other state.
Export rules deserve to be read as an incentive. In a retail net metering state, every exported kilowatt-hour is worth the full retail rate; under net billing or avoided-cost compensation, the same kilowatt-hour can be worth a third of that. For a Indiana home at an assumed $0.15/kWh, that difference compounds across a 25-year system life.
What this means for your numbers
A typical 8 kW system in Indiana costs roughly $19,600–$25,600 installed before incentives, producing about 10,240 kWh a year and saving around $1,266 in year one — a simple payback near 15–20 years with no incentives applied. Anything in the table above shortens that.
Frequently asked questions
What are Indiana solar tax credits worth in 2026?
Indiana offers no residential solar income tax credit in 2026, and the 30% federal credit ended for systems installed after December 31, 2025. What remains on the tax side is sales and property tax exemptions, which lower cost indirectly rather than paying you back.
Does Indiana have solar rebates?
No. Indiana has no statewide solar rebate or upfront grant program in 2026. Individual utilities and municipalities occasionally run their own, so it is worth asking your utility directly.
Is there an Indiana solar property tax exemption?
Yes. Indiana excludes the value solar adds to a home from property tax assessment, so a system that raises your home's value does not raise your annual tax bill. Indiana also exempts qualifying solar equipment from state sales tax, which comes straight off the installed price.
What solar incentives are available in Indiana in 2026?
Indiana offers property and sales tax exemptions for solar but no state tax credit or rebate. Because the federal Section 25D credit ended for systems installed after December 31, 2025, these state, local and utility programs are now the entire incentive picture for a purchased system.
Is there still a 30% federal solar tax credit in Indiana?
No. The 30% federal residential clean energy credit (Section 25D) ended for systems installed after December 31, 2025 under the One Big Beautiful Bill Act. Any quote or website still applying 30% to a 2026 purchased installation is out of date. Leased and PPA systems can still benefit indirectly, because the third party that owns the system may claim the commercial 48E credit through 2027 and pass some of the value through in pricing.
Does Indiana have net metering?
Indiana phased out retail net metering for new customers in 2022. Investor-owned utilities now credit exports at roughly 1.25× wholesale (an "excess distributed generation" rate), well below retail. Export rules are effectively an incentive — often the largest one — because they set what every kilowatt-hour you do not use on site is worth.
How much do incentives change the cost of solar in Indiana?
Before incentives, a typical 8 kW system in Indiana runs roughly $19,600–$25,600. With no state credit or rebate available, that figure is close to what you would actually pay. See our full Indiana cost breakdown for payback math.
