Solar Panels in Tennessee (2026 Guide)

Q: How much do solar panels cost in Tennessee in 2026?

Roughly $2.50 to $3.50 per watt before incentives (typically near $3.00) — about $14,500 to $15,000 for a 5 kW system and $29,000 to $30,000 for 10 kW.

Q: Does Tennessee have a solar tax credit or rebate?

No. There is no state credit or rebate — only a property-tax assessment cap. The federal credit also expired December 31, 2025.

Q: Does Tennessee have net metering?

No traditional retail net metering. TVA and local utilities pay only about 2 to 4 cents per kWh for exported power, so the savings come from using your own solar, not selling it back.

Q: Should I add a battery in Tennessee?

Often yes. Since exported power earns only a few cents, storing your solar to use in the evening usually beats sending it to the grid.

We'll be upfront: Tennessee is one of the tougher states for solar economics, and we'd rather tell you that than sell you a number that doesn't hold up. There's no state credit, electricity is cheap, and TVA pays only a few cents for the power you export. That doesn't mean solar never works here — it means it works differently. This guide shows you how the math actually plays out in 2026.

How Much Do Solar Panels Cost in Tennessee?

Tennessee installs run roughly $2.50–$3.50 per watt before incentives, typically near $3.00. For a typical home system:

5 kW system: ~$14,500–$15,000
10 kW system: ~$29,000–$30,000

Your real price depends on your roof, equipment, and installer. See our 2026 solar cost breakdown.

Tennessee Solar Incentives in 2026

No federal tax credit in 2026

The 30% federal residential solar tax credit expired December 31, 2025 and is not available in 2026. A lot of Tennessee solar pages still quote prices that secretly include it — don't trust those. See our 2026 tax credit guide.

No state tax credit or rebate

Tennessee has no state solar tax credit and no statewide rebate. The one state provision worth knowing is the Green Energy Property Tax Assessment, which caps how much a solar system can raise your property's taxable value (state law limits the added assessed value to a fraction of installed cost). It limits a downside rather than handing you cash.

Watch out for "free solar" scams

Tennessee was awarded federal "Solar for All" money, but the program was terminated and is not available — and the state has warned about scammers using the "Solar for All" name to pitch free panels. If someone offers you free solar under that program, be skeptical.

How You Get Paid for Solar in Tennessee (the key part)

This is the single most important thing to understand here. Tennessee has no traditional retail net metering. Most of the state is served by TVA and local power companies that follow TVA's rules, and:

Power you use the moment you produce it offsets electricity you'd otherwise buy at the retail rate (~13¢/kWh) — that's where your savings come from.
Power you export to the grid is paid at TVA's low "avoided cost" — roughly 2–4¢/kWh, a fraction of retail.

In plain terms: in Tennessee, the value is in using your own solar, not selling it back. Over-sizing a system to bank credits — the model that works in net-metering states — doesn't work here. The systems that pay off are sized to match your daytime usage, and batteries make extra sense because storing your solar for evening use beats exporting it for pennies. (Your specific local power company — NES, MLGW, KUB, EPB and others — sets its own interconnection terms under TVA, so confirm yours.)

Major Tennessee Electricity Providers & Rates

TVA generates the power, and it's delivered by about 150 local power companies, including Nashville Electric Service (NES), Memphis Light, Gas & Water (MLGW), Knoxville Utilities Board (KUB), and EPB Chattanooga. Tennessee's residential rates are low — around 13¢ per kWh, roughly 25% below the national average. Cheap power is easy on your wallet but means each kWh your panels offset saves less, which lengthens payback.

Is Solar Worth It in Tennessee in 2026?

For the right household, yes — but it's a narrower case than in most states, and the math rewards smart design over big systems. The headwinds are real: no federal credit, no state credit or rebate, no retail net metering (exports pay ~2–4¢), and low retail rates. Where it still works: homes with high daytime electricity use (so most solar is self-consumed), homeowners adding battery storage to shift solar into the evening, and people who value energy independence and a hedge against future rate increases more than a fast payback. The model that pays off in Tennessee is a right-sized system that minimizes grid export — not a maximized one. A custom quote built around your actual usage shows whether it makes sense for you.
