Solar Panels in
Tennessee

Not in Tennessee?

Tennessee is where solar sales pitches go to get audited. Every utility in the state buys power through TVA, there is no retail net metering, and exported solar earns roughly 3 to 6¢ per kilowatt-hour against 11 to 12¢ retail. A typical system's surplus is worth about $52 a year here, not $500. Solar still works in Tennessee, but only sized to what your house actually uses. EcoGen America gives you that math before an installer gives you theirs.

In Tennessee, Surplus Is Worth $52 a Year. Size for It.

Tennessee is where solar sales pitches go to get audited. Every utility in the state buys power through TVA, there is no retail net metering, and exported solar earns roughly 3 to 6 cents against 11 to 12 cents retail.

A typical system’s surplus is worth about $52 a year here, not $500, and any quote implying otherwise is quoting a different state.

Solar still works in Tennessee, but only sized to what your house actually uses, where every kilowatt-hour offsets the full retail rate.

EcoGen America gives you that math before an installer gives you theirs.

Self-Use Sizing

With surplus worth about $52 a year, oversizing is pure waste. We size Tennessee systems to the load inside the house.

Quote Analysis

Built-in checks for net metering assumptions TVA territory does not offer, export income at real rates, and honest offset math.

Local Policy

We track TVA distributor crediting terms and the local power company rates that set the self-use value.

The $52 Question: What Tennessee Exports Really Earn

One concrete roof, so the stakes are visible. A 10 kW system in Murfreesboro sending 1,500 kWh a year back to the grid:

Compensation Regime
Export Value
Annual Income on 1,500 kWh
Tennessee (TVA avoided cost)
~3 – 6¢/kWh
~$52
A true retail net-metering state
~11.5¢/kWh
~$172
Power you never export (self-consumed)
Full retail avoided, 11 – 12¢/kWh
The entire business case
Illustrative math at July 2026 rates; export compensation varies by local power company program. The gap between rows one and three is why sizing is everything in Tennessee.

Read the third row twice. Tennessee solar is not a power-selling business; it is a power-not-buying business. Every design decision follows from that.

Meter, Model, Match: The Tennessee Sequence

1

Meter

Pull 12 months of bills from your local power company. Your daytime usage, not your roof size, sets the right system.

2

Model

Insist on a projection that prices exports at avoided cost, a few cents, and self-consumption at retail. If those two rates match, the model is wrong.

3

Match

Choose installers who build self-consumption systems in TVA territory routinely and can show local interconnections to prove it.

When Tennessee Solar Says Not Yet

In a 4¢-export state, the disqualifiers do more work than the sales pitch. Walk away, or wait, if:

  • Your daytime usage is low and a battery is not in budget. Exports at avoided cost will not rescue a system nobody is home to use.
  • The quote leans on “net metering.” Tennessee has none at retail. A pitch using the phrase either misunderstands TVA territory or hopes you do.
  • The payback assumes tax credits. The federal residential credit ended December 2025 and Tennessee offers no state income-tax credit. Current quotes carry neither.
  • The array is sized far past your annual usage. Overshoot manufactures 4¢ exports; it is the most common way Tennessee buyers overpay.
  • Your roof shades out mid-day. Self-consumption states live and die on midday production; a shaded noon guts the whole case.

Steady daytime load, clear roof, right-sizing: that homeowner still does well in Tennessee, and knows exactly why.

Tennessee Contract Checks

Tennessee Quotes: Four Tests That Matter

TVA territory has no room for optimistic paperwork. Apply these four tests to any quote.

Clause to verify: Find the export rate in the model. If it is above ~6¢/kWh, ask which Tennessee program pays it. None do.
Clause to verify: Compare projected annual kWh against your last 12 bills; ask the installer to justify anything above ~100% of usage.
Clause to verify: Ask for three completed interconnections with your specific utility in the past year.
Clause to verify: Both prices side by side; a financed total far above cash means the fee moved into your loan.
Verify your paperwork

Four tests, any Tennessee quote. Good installers pass them in one sitting.

Green Power Providers Is Closed: Tennessee Programs, Dated

Tennessee’s program history confuses buyers because the good one is gone. The current state of play:

  • Green Power Providers, closed. TVA’s legacy program that paid retail-ish rates for rooftop solar stopped taking applications years ago. Systems enrolled then keep their contracts; nothing about it applies to a 2026 purchase.
  • Dispersed power production is the current lane: surplus energy is purchased near TVA’s avoided cost, the 3 to 6¢ figure that runs through this page.
  • Your local power company sets the paperwork. Interconnection, metering and any local rider vary between the state’s utilities under the same TVA umbrella; your installer should know yours by name.
  • TVA’s Quality Contractor Network exists and is worth asking about: membership is a reasonable signal an installer works these rules routinely.

If a pitch cites a Tennessee program by name, date it. The ones that paid well are closed; the ones that are open pay avoided cost.

Tennessee Solar FAQs

Does Tennessee have net metering?

No. Every Tennessee utility operates under TVA, and surplus rooftop solar is compensated near avoided cost, roughly 3 to 6¢/kWh, rather than the retail rate.

That single fact drives every good Tennessee solar decision: size to what you use, not to what you could export.

What will I earn selling power back in Tennessee?

Little, by design. A 10 kW system exporting 1,500 kWh a year earns around $52 in credits at avoided-cost rates; the same exports would return about $172 under retail net metering elsewhere.

The real value is the 11 to 12¢ retail power your system keeps you from buying.

Is solar worth it in Tennessee at all?

For the right house, yes. Steady daytime usage, a clear roof and right-sizing let a system pay back on avoided retail power alone at decent regional install prices.

For low-usage households without battery budgets, the math is thin, and a good adviser says so.

What happened to TVA’s Green Power Providers program?

It closed to new applicants years ago. Systems enrolled during the program keep their contract terms, but no comparable retail-rate program exists for new Tennessee installations.

Current surplus power falls under dispersed-power arrangements near avoided cost.

Are there tax credits for solar in Tennessee?

No state income-tax credit exists, and the federal residential credit ended in December 2025.

A 2026 Tennessee quote listing tax credits is out of date; ask for the projection without them.
