Home Solar Cost Guide

What Tennessee pays for your exported solar power

Export compensation is the single biggest payback lever in 2026. Here is Tennessee's current rule in plain words, with the official source.

Under Tennessee's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.

Installed home solar for Viola homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.

Viola, Tennessee has about 112 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.

Beware of any 2026 payback estimate that looks as good as the 2025 ones: with the federal credit gone, a third of the old subsidy math vanished. If a sales projection has not gotten noticeably worse since 2025, it is hiding something - usually an inflated utility-rate escalation assumption.

Whether solar still pays in Tennessee after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Tennessee rules that decide your payback

RuleTennessee 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 incentiveNo state-level incentive; utility rebates may apply
Sales tax on the systemExempt
Property tax on added home valueNo 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.

Getting Viola quotes

Marketplace platforms collect bids from multiple TN installers against the same spec, which is the only clean way to compare - same roof, same size, different prices. Getting quotes is free and does not commit you to anything; prices come from the installers, never from this site.

Common questions

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.

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.

Is there still a federal solar tax credit in 2026?

No. The 30% Residential Clean Energy Credit was repealed effective for systems placed in service after December 31, 2025, per the IRS. Only systems finished by the end of 2025 qualified. State-level incentives are separate and some survive - check the state page in this guide.

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.

Does solar raise my property taxes?

It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
