Tennessee Solar Incentives in 2026: What Actually Saves You Money

As of January 1, 2026, the federal 30% solar tax credit and efficiency credits have ended for new systems. This is a hard deadline with no phase-down or partial credit available. If you're considering solar or heat-pump upgrades in Tennessee this year, the financial case now rests entirely on state, utility, and local incentives—and those are often substantial.

Tennessee homeowners still have access to net-metering credits, utility rebates, state property-tax exemptions, and local efficiency programs. Because these vary by utility and location, the fastest way to identify which incentives apply to your home is a free 3-minute assessment that pinpoints your highest-leverage next step.

What Ended on January 1, 2026

The federal residential clean-energy credit under IRS §25D (the 30% solar investment tax credit) is no longer available for solar systems placed in service on or after January 1, 2026. Similarly, the efficiency credit under §25C for heat pumps, insulation, and weatherization ended on the same date.

There is no phase-down, no partial credit, and no exceptions. If you installed a system before December 31, 2025, you may still claim the credit on your 2025 tax return; systems installed in 2026 and later do not qualify.

Tennessee Incentives That Still Work in 2026

State and utility incentives were not affected by the federal change. Tennessee homeowners can still benefit from net-metering or export-credit arrangements with their utility, which allow you to earn credits for excess solar energy sent to the grid. Many utilities also offer rebates for solar installation or energy-efficiency upgrades.

Tennessee provides property-tax exemptions for solar equipment and may offer sales-tax exemptions depending on your utility and location. Local efficiency programs, weatherization assistance, and heat-pump incentives may also be available through your utility or municipality.

Because incentive rules, dollar amounts, and eligibility vary by utility and county, the authoritative and regularly-updated source for any Tennessee incentive is DSIRE (Database of State Incentives for Renewables & Efficiency). Your utility's website is also the best place to confirm current rebate programs and net-metering terms.
