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 - Blaine 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 Blaine homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
If a salesperson in Blaine 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.
Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.

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 Blaine roofs
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.

Getting Blaine quotes
Before requesting quotes, have your last 12 months of electricity bills handy - system sizing should follow your real usage, not a salesperson's template. A bid sized far above your usage is a margin play, especially now that surplus export pays less in most states.

Common questions
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.
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.
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 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 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.
