KnoxvilleSolar Incentives 2026: Rebates, Tax Credits & Net Metering
Knoxville homeowners stack the 30% federal tax credit and KUB (TVA) solar buyback. At 4.5 peak sun hours a day, a home with a $130/month bill (about 929 kWh) needs roughly a 8.6 kW system — 22 panels — and pays back in about 9.7 years.
Solar Incentives Available in Knoxville
Solar incentives in Knoxville 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, KUB (TVA) sets the local rules for crediting the solar power you export.
KUB delivers TVA power in Knoxville; TVA's lack of retail net metering makes self-consumption and batteries key.
How Much Solar Knoxville Homes Produce
Knoxville gets 4.5 peak sun hours a day, so each 1 kW of panels produces about 1,314 kWh per year here. A 8.6 kW system — the size that fits a typical $130/month KUB (TVA) bill — generates roughly 11,300 kWh annually, worth about $1,582 in avoided electricity in year one and more as rates rise.
KUB (TVA) Net Metering in Knoxville
Tennessee has no statewide retail net metering mandate, so KUB (TVA) buys back exported solar at a reduced rate (~25–50% of retail). In Knoxville, that often makes a battery worthwhile — storing your own production beats exporting it cheaply. See full Tennessee net metering rules →
