Home solar in Tennessee: prices, net metering, what is left in 2026
What Tennessee homeowners pay for solar in 2026, how the state's export rules work, and which incentives survived - verified against state sources, town by town.
Installed home solar in Tennessee compares against the U.S. marketplace average of about $2.58 a watt - roughly $30,960 for 12 kW.
The 30% federal solar credit ended December 31, 2025 - Tennessee installations completed in 2026 get $0 from it.
A home battery in Tennessee runs about $12,000-$16,000 installed, before any state storage incentive.
The honest 2026 answer for Tennessee: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is Tennessee's export compensation, covered in the net metering section.
Tennessee rules that decide your payback
| Rule | Tennessee status |
|---|---|
| Export compensation (net metering) | There is no state net-metering law reaching virtually any Tennessee homeowner — TVA, a federally-owned and self-regulated corporation, supplies about 99.7% of the state's electricity service territory through 153 local power companies, so rooftop solar export terms are set by TVA and those local utilities rather than by a state regulator. |
| State incentive | No state-level incentive; utility rebates may apply |
| Sales tax on the system | Exempt |
| Property tax on added home value | No exclusion on record |
Tennessee homeowners have no public utility commission to appeal solar compensation to: the state's own energy office notes TVA 'is self-regulated' and that the single distribution utility not served by TVA, Appalachian Power, is the only one under Tennessee Public Utility Commission jurisdiction.

The 30% federal tax credit is gone for 2026 installations
The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.
Common questions
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
How do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
What is net metering and why does it decide everything?
It is the rule for how your utility credits electricity you export. Full retail net metering credits exports at the same rate you pay - the grid works like a free battery. Net billing or avoided-cost rules pay far less per exported kWh, which lengthens payback and strengthens the case for a home battery.
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
