Tennessee solar incentives in 2026
Last updated · every TN program below is verifiable against the sources at the foot of this page.
Tennessee offers no significant state-level solar incentive. Economics here depend almost entirely on electricity rates and what your utility pays for exported power.
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 Tennessee this year, there is no federal credit. That is a roughly $7,560 swing on an $25,200 system compared with 2025 pricing, and it is why state programs matter more now than they did a year ago.

Tennessee solar tax credit
There is no Tennessee solar tax credit in 2026, and no federal one either — Section 25D ended for systems installed after December 31, 2025. That makes your electricity rate and your utility's export credit the whole of the economics here.
Tennessee solar rebates and grants
Tennessee 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.
Tennessee offers no state solar tax credit or rebate for homeowners.
Net metering and export rates in Tennessee
Tennessee has no net metering. TVA-served utilities (nearly the whole state) buy exports, if at all, at low wholesale-linked rates under TVA programs.
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 Tennessee home at an assumed $0.13/kWh, that difference compounds across a 25-year system life.
What this means for your numbers
A typical 8 kW system in Tennessee costs roughly $19,200–$25,200 installed before incentives, producing about 10,720 kWh a year and saving around $1,148 in year one — a simple payback near 17–22 years with no incentives applied. Anything in the table above shortens that.
Frequently asked questions
What are Tennessee solar tax credits worth in 2026?
Tennessee offers no residential solar income tax credit in 2026, and the 30% federal credit ended for systems installed after December 31, 2025. There is no state tax benefit to claim at all, so the economics rest on your electricity rate and export credit.
Does Tennessee have solar rebates?
No. Tennessee 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 a Tennessee solar property tax exemption?
No. Tennessee does not exempt residential solar from property tax assessment, so a system that increases assessed value can increase your property tax. Assessment practice varies by county — ask your local assessor how they treat rooftop solar.
What solar incentives are available in Tennessee in 2026?
Tennessee offers no state solar tax credit or rebate for homeowners. In short, Tennessee homeowners are largely relying on utility export compensation rather than incentives. 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 Tennessee?
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 Tennessee have net metering?
Tennessee has no net metering. TVA-served utilities (nearly the whole state) buy exports, if at all, at low wholesale-linked rates under TVA programs. 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 Tennessee?
Before incentives, a typical 8 kW system in Tennessee runs roughly $19,200–$25,200. With no state credit or rebate available, that figure is close to what you would actually pay. See our full Tennessee cost breakdown for payback math.
