Tennessee has one of the weakest solar incentive markets in the U.S. In 2026, homeowners should know three things upfront: Tennessee has no state solar tax credit, no statewide solar rebate, and no net metering. The federal residential solar tax credit also ended for purchased home systems whose installation is completed after December 31, 2025.
That does not mean Tennessee has no solar benefits at all. The remaining options are limited but important: TVA’s Dispersed Power Production program for excess solar generation, favorable property tax treatment for certified systems, possible income-qualified Solar for All funding, and state contractor licensing rules that protect homeowners from unqualified installers.

Tennessee Solar Incentives at a Glance
Here are the solar incentives Tennessee homeowners can, and cannot, use in 2026:
| Incentive | Status in Tennessee |
|---|---|
| State solar tax credit | Does not exist |
| State solar rebate | None |
| Federal residential solar tax credit | $0 for purchased systems completed after Dec. 31, 2025 |
| Federal commercial solar credit | May apply only to third-party-owned systems; current-terms construction-start deadline has passed |
| Net metering | Not available in Tennessee |
| TVA Dispersed Power Production | Active; buys excess output at avoided cost, starting around 3.6¢/kWh |
| Green Energy Property Tax Assessment | Caps taxable solar value at 12.5% of installed cost if certified by TDEC |
| Solar for All | $156M+ federal award administered by TDEC; confirm current status before relying on it |
| Contractor licensing protection | State license required for solar projects of $25,000 or more |
Every incentive on a Tennessee solar quote should fit into this table. If a salesperson claims a different tax credit, rebate, or export payment, verify it directly with the agency or utility that supposedly administers it.
Does Tennessee Have a State Solar Tax Credit?
Tennessee does not have a state solar tax credit. The main reason is structural: Tennessee has no broad personal income tax. In states like South Carolina or Arizona, the solar tax credit works by reducing a homeowner’s state income tax bill. Tennessee homeowners do not have that kind of state income tax liability, so there is no comparable tax bill for a residential solar credit to offset.
Tennessee also does not have a Renewable Portfolio Standard, or RPS. In many states, an RPS requires utilities to procure renewable energy and often helps create rebate programs, solar carve-outs, or renewable energy certificate markets. Tennessee does not have that mandate.
Those two facts explain why Tennessee’s solar incentive landscape is so thin. There is no state income tax credit to claim, no broad state rebate pool to draw from, and no renewable mandate pushing utilities to pay homeowners premium rates for solar production. For most Tennessee homeowners, the economics of solar come from lowering the amount of electricity bought from the grid.
The Federal Solar Tax Credit Is Over for Purchased Home Systems
What Changed in 2026
The federal residential clean energy credit under Section 25D is worth $0 for homeowner-owned solar systems whose installation is completed after December 31, 2025, under the One Big Beautiful Bill Act provisions summarized by the IRS. There was no phase-down and no 2026 grace period for ordinary purchased residential systems.
Here is what that means for a typical Tennessee solar installation, using our standard sizing assumptions:
| Figure | Tennessee Value |
|---|---|
| Typical system size | 10.2 kW, sized to offset average household usage of 1,154 kWh/month |
| Installed cost | $31,008 at Tennessee’s $3.04/W index price |
| Former 30% federal credit | $9,302 |
| Federal credit for the same purchase in 2026 | $0 |
A 2026 quote for a purchased Tennessee solar system should not include a 30% federal tax credit. If it does, the quote is using outdated assumptions, and the payback period is likely overstated.
What About Solar Leases and PPAs?
The commercial clean electricity credit under Section 48E can still apply to some residential solar systems owned by a third party, such as a lease or power purchase agreement where the solar company owns the panels. In Tennessee, that path has two major caveats:
- The construction-start deadline of July 4, 2026 for current credit terms has passed. Any provider claiming the commercial credit should explain the current eligibility basis in writing.
- Residential solar PPA legality in Tennessee is unclear. The DSIRE third-party solar PPA policy map, May 2026 edition found no Tennessee authority addressing residential PPAs. If a company offers one, ask what legal basis the contract relies on.
Bottom line: a purchased home solar system in Tennessee no longer qualifies for the residential federal solar tax credit in 2026. A lease or PPA may involve different tax treatment, but homeowners should treat those offers as contract questions, not automatic incentive replacements.
Does Tennessee Have Net Metering?
Tennessee does not have net metering. It has never had a statewide net metering statute, and the Tennessee Public Utility Commission cannot create net metering for most households in the state.
The reason is TVA. Most Tennessee homes buy power from local power companies supplied by the Tennessee Valley Authority, a federal utility. TVA’s rates and renewable programs sit outside the Tennessee Public Utility Commission’s normal retail-rate authority.
How TVA’s Dispersed Power Production Program Works
Instead of net metering, Tennessee solar customers may be able to use TVA’s Dispersed Power Production program. The program is offered through local power companies and uses five-year agreements.
The key difference is how excess solar power is valued:
- Net metering usually credits exported solar near the retail electricity rate.
- TVA’s Dispersed Power Production program buys exported solar at TVA’s avoided cost.
That difference matters because TVA’s avoided-cost payment is far below the average retail electricity rate in Tennessee.
| Rate | Value |
|---|---|
| Tennessee average residential electricity rate | 13.48¢/kWh, EIA March 2026 |
| TVA export rate, first tier | $36.35/MWh, or 3.635¢/kWh, under the September 2025 flat 7×24 schedule |
| TVA time-differentiated export rates | 3.2¢ to 4.3¢/kWh |
| Export value compared with retail value | Roughly 30% to 33% |
In plain English: TVA pays roughly 30¢ to 33¢ for every dollar of retail electricity value that a homeowner exports at typical TVA-area rates. That is why self-consuming solar power matters much more in Tennessee than it does in strong net-metering states.
Example: Annual Solar Value on a 10.2 kW Tennessee System
A 10.2 kW Tennessee solar system produces about 13,852 kWh per year using the state’s 1,358 kWh/kW/year production factor. The value of that electricity depends on whether the household uses it directly or exports it to TVA.
| Where the solar power goes | Annual value |
|---|---|
| Used at home | $1,525 to $1,660, by avoiding retail purchases at typical TVA-area rates of 11¢ to 12¢/kWh |
| Exported to TVA | $504, paid at 3.635¢/kWh |
Over a five-year Dispersed Power Production agreement, full export would be worth about $2,518. The same production used at home would be worth about $9,337.
For Tennessee homeowners, this changes system design. A solar array should be sized around daytime electricity use, not just annual consumption. Batteries may also be worth considering if they help shift solar production from low-value exports to higher-value self-consumption.
Closed TVA Programs and Local Utility Fees
TVA’s older Green Power Providers program, which paid better rates, closed to new enrollment after 2019. Some local power companies also add distributed generation fees, interconnection charges, or riders authorized under TVA’s framework.
Before signing a solar contract, ask your local power company how it handles residential solar customers. Major Tennessee power providers include:
- Nashville Electric Service
- Memphis Light, Gas and Water
- Middle Tennessee EMC
- Knoxville Utilities Board
Rules and fees can vary by municipal utility or electric cooperative, so verify the details with your specific provider.

Tennessee’s Green Energy Property Tax Assessment
Tennessee’s main state-level solar benefit is the Green Energy Property Tax Assessment under Tenn. Code Ann. § 67-5-601. For certified solar systems, the taxable value attributed to the solar equipment is capped at 12.5% of installed cost.
For example, on a $31,008 Tennessee solar system, the solar addition would be assessed at $3,876 of taxable value instead of the full installed cost.
This is not an automatic exemption. The system must be certified as a green energy production facility by the Tennessee Department of Environment and Conservation. The certification must then be filed with the Comptroller’s office by March 1 of the first year the valuation is claimed.
Homeowners should build that certification step into the installation timeline. Otherwise, the property tax benefit may be missed during reassessment.
Tennessee also has a sales tax pathway under § 67-6-346 for machinery and equipment at certified green energy production facilities, but it functions as a business-facing credit. Residential homeowners should not expect to claim it on a home solar installation.
Solar for All and Local Tennessee Solar Programs
Tennessee received more than $156 million through the federal Solar for All program, administered by TDEC, to expand solar access for income-qualified and disadvantaged households. Because federal policy changes have affected implementation timelines, homeowners should confirm current status, eligibility, and funding availability directly with TDEC’s Office of Energy Programs before relying on the award.
For income-qualified Tennesseans, Solar for All is the one program on this page that may be worth watching closely.
Local utilities may also offer occasional rebates, loans, or financing programs. These programs are utility-specific and can change quickly. Confirm any local incentive through the utility’s own website or the DSIRE database for Tennessee, not only through a salesperson’s proposal.
How Tennessee Solar Incentives Compare Nationally
Tennessee’s weak incentive market matters because the state’s underlying solar economics are also more challenging than average. The numbers show why:
Index measure | Tennessee | Compared with U.S. average | National rank |
|---|---|---|---|
Residential electricity rate | 13.48¢/kWh | 24.7% below average | 39th highest of 51 |
Installed solar cost | $3.04/W | 4.8% above average | 37th cheapest of 51 |
Peak sun hours | 4.89 | Solid mid-tier solar resource | Mid-tier |
Tennessee homeowners pay slightly more than average to install solar and save less than average for each kilowatt-hour they avoid buying. Without a state tax credit, rebate, or net metering program, the payback calculation depends heavily on self-consumption and long-term ownership.
The broader purchase question deserves a separate look in are solar panels worth it in Tennessee.
Who Tennessee Solar Incentives Help, and Who They Don’t
Tennessee’s remaining solar incentives are narrow. They may help homeowners who own their property, can use most of their solar power during the day, qualify for property tax treatment, or may be eligible for income-qualified Solar for All support.
They are less useful for:
- Renters. Most benefits require homeownership and control over the property.
- Homeowners expecting retail-rate export credits. Tennessee does not have net metering, and TVA export payments are far below retail electricity rates.
- Buyers counting on the federal tax credit. The residential 25D credit is $0 for purchased systems whose installation was completed after December 31, 2025.
- Short-tenure homeowners. With no major upfront incentive, solar savings may take years to recover the installed cost.
- Anyone offered a PPA as the workaround. Residential PPA legality in Tennessee is unclear, and the current-terms construction-start deadline for the commercial credit has passed.
If one of these describes your situation, that is the actual Tennessee policy environment.
How to Verify a Tennessee Solar Incentive Claim
Because Tennessee’s incentive list is short, some sales materials rely on expired, out-of-state, or misleading incentive claims. Before signing a contract, use this three-step check:
- Ask who administers the incentive. Real incentives have a responsible administrator, such as the IRS, TVA, TDEC, your local utility, or another named agency.
- Find the program on the administrator’s website. Do not rely only on a quote, brochure, or third-party article.
- Match the number. The credit amount, rebate amount, export rate, or deadline should match the figure on the administrator’s own page.
The most common bad claims in Tennessee are a 30% federal tax credit on a purchased 2026 system, retail-rate payments for exported solar power, government-funded free solar panels, and urgency claims around programs with no stated cap or deadline.
Where Tennessee Solar Incentives Leave Homeowners
Tennessee has no state solar tax credit, no statewide rebate, no net metering, and no federal residential credit for purchased systems whose installation was completed after December 31, 2025. Excess solar power sold through TVA is worth far less than power used directly in the home.
Solar can still make sense for some Tennessee homeowners, especially those with strong daytime electricity use, long expected homeownership, and a properly sized system. The state’s core solar math is based on 4.89 peak sun hours, installed costs around $3.04/W, and avoided retail purchases at typical TVA-area rates of 11¢ to 12¢/kWh.
For the next step, compare these incentives with the full savings case in are solar panels worth it in Tennessee, the price breakdown in the cost of solar panels in Tennessee, the financing claims in free solar panels in Tennessee, and installer vetting guidance in top solar companies in Tennessee.

Frequently Asked Questions
No. Tennessee does not have a state solar tax credit, and none is pending. Because Tennessee has no broad personal income tax, there is no state income tax bill for a residential solar credit to offset.
Not for a system you purchase. The federal residential solar tax credit is $0 for homeowner-owned systems whose installation is completed after December 31, 2025. A commercial credit may apply to some third-party-owned systems, but current-terms timing has passed and residential PPA legality in Tennessee is unclear.
No. Tennessee does not have statewide net metering. Most households are served by local power companies supplied by TVA, and the alternative program is TVA’s Dispersed Power Production program, which pays avoided-cost rates for exported solar power.
Under the September 2025 Dispersed Power Production schedule, TVA paid $36.35/MWh, or 3.635¢/kWh, in the first flat 7×24 pricing tier. Time-differentiated rates ranged from 3.2¢ to 4.3¢/kWh. TVA posts updated prices monthly.
Only slightly if the system is certified. Tennessee’s Green Energy Property Tax Assessment caps the taxable value of certified solar equipment at 12.5% of installed cost. Certification through TDEC and filing with the Comptroller’s office are required.
Their status is unclear. DSIRE’s May 2026 policy review found no Tennessee authority addressing residential solar PPAs. If a company offers a lease or PPA, ask for the legal basis of the contract in writing before signing.
No government or utility program gives every Tennessee homeowner free solar panels. Offers marketed as “free solar” are usually loans, leases, or PPAs with real costs. In Tennessee, third-party ownership claims also require extra scrutiny because PPA legality is unclear.
System size, installed cost, production, and savings figures on this page are computed from the EcoGen 50-State Solar Index, Tennessee entry (electricity rate as of March 2026; cost index as of June 2026), using standard assumptions: systems sized to offset average household consumption, a 1,358 kWh/kW/yr Tennessee production factor, and $3.04/W installed cost.
