What Tennessee still offers after the federal credit ended
Every incentive on this page is verified against Tennessee government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Farragut systems completed in 2026 get $0 from it.
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 Farragut homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
If a salesperson in Farragut tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: Tennessee's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

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.

What this means for Farragut roofs
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.

Getting Farragut quotes
Same-day contracts are a red flag in this industry. Legitimate TN installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions
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.
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.
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 much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
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.
