NashvilleSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Nashville homeowners stack the 30% federal tax credit and Nashville Electric Service (TVA) solar buyback. At 4.6 peak sun hours a day, a home with a $135/month bill (about 964 kWh) needs roughly a 8.7 kW system — 22 panels — and pays back in about 9.5 years.
Solar Incentives Available in Nashville
Solar incentives in Nashville come in three layers. First, every homeowner qualifies for the 30% federal Residential Clean Energy Credit on the full installed cost, claimed on IRS Form 5695. Tennessee does not add a state income tax credit, so the federal credit is the main up-front incentive. Third, Nashville Electric Service (TVA) sets the local rules for crediting the solar power you export.
Nashville Electric distributes TVA power, and TVA has no traditional retail net metering — battery self-consumption drives the economics.
How Much Solar Nashville Homes Produce
Nashville gets 4.6 peak sun hours a day, so each 1 kW of panels produces about 1,343 kWh per year here. A 8.7 kW system — the size that fits a typical $135/month Nashville Electric Service (TVA) bill — generates roughly 11,686 kWh annually, worth about $1,636 in avoided electricity in year one and more as rates rise.
Nashville Electric Service (TVA) Net Metering in Nashville
Tennessee has no statewide retail net metering mandate, so Nashville Electric Service (TVA) buys back exported solar at a reduced rate (~25–50% of retail). In Nashville, that often makes a battery worthwhile — storing your own production beats exporting it cheaply. See full Tennessee net metering rules →
