Net metering, tax credits and incentives in 2026
Tennessee pays less than retail for exported solar power. Under TVA Dispersed Power Production, power you send to the grid earns about 2.6¢/kWh, against 13.9¢ for power you buy. We assume 40% of a no-battery system's output is used at home as it's produced (worth the full price) and the rest is exported, so each solar kWh is worth about 7.1¢. Using more of your solar yourself, by running appliances midday or adding a battery, raises that.
Tennessee has no net metering; TVA buys exports through its Dispersed Power Production program at about 2-3¢ per kWh, and local power companies may add a monthly fee. Source.
There is no federal tax credit for buying home solar installed in 2026. The 30% Residential Clean Energy Credit (Section 25D) ended for systems placed in service after December 31, 2025, so the costs and paybacks on this page include no federal credit.
Tennessee and local utilities may still offer rebates, performance payments, property-tax or sales-tax exemptions. Search the DSIRE incentives database for Tennessee and ask installers which programs they apply for you.
