What solar incentives and tax credits are available in Nashville and Tennessee?

In 2026, there is no federal tax credit for a solar system a Nashville homeowner buys. The 30 percent Residential Clean Energy Credit (Section 25D) ended for systems installed after December 31, 2025. What is left is narrower: the business 48E credit for leases, PPAs, and commercial projects, depreciation for businesses, limited NES buyback programs, and a few targeted Tennessee provisions.

In Middle Tennessee, there is no large statewide “Tennessee solar tax credit” and there is no traditional 1-for-1 net metering in TVA territory. That means your financial picture is driven mainly by your installed price and how much of your own solar you use at home, not by utility rebates or simple retail buyback programs.

The federal homeowner credit ended after 2025

For a homeowner in Nashville, Franklin, Brentwood, Mt Juliet, Bellevue, Gallatin, Donelson, or East Nashville, the old starting point was the federal Residential Clean Energy Credit, worth 30 percent of a solar and battery install.

That changed with the One Big Beautiful Bill Act, signed July 4, 2025. The credit ended for systems installed after December 31, 2025, and the IRS now states it is not available for property placed in service after that date. Battery storage installed by a homeowner is in the same boat.

So when we price a solar or solar plus battery system for a Bellevue or Franklin home in 2026, the installed price is the price. Residential solar here runs about $2.85 to $3.50 per watt installed, before incentives, so a typical 8 to 14 kW home system lands around $22,800 to $49,000. A Tesla Powerwall 3 runs about $15,400 installed, and Enphase IQ batteries run $12,000 to $18,000.

If your system was installed and placed in service by December 31, 2025, talk to your tax professional about claiming it on your 2025 return using Form 5695, Residential Energy Credits.

How to anchor this in official federal guidance

For accuracy and compliance, your accountant should work from three primary sources:

The IRS “Residential Clean Energy Credit” page, which now states the credit is not available for property placed in service after December 31, 2025.

The IRS “Home energy tax credits” page, which places the Residential Clean Energy Credit alongside the home improvement credit and explains how they interact.

The IRS “About Form 5695” page and the instructions for Form 5695, which matter only for systems placed in service by the end of 2025.

Energy Star and the U S Department of Energy also publish plain language summaries. Some older pages still show the 30 percent credit as available through 2032. Go by the current IRS pages and your tax professional.

Our role as The Solar Roofers is to provide clean invoices that separate solar, batteries, roofing, and electrical work, plus as built documentation. Your tax advisor uses those documents alongside the IRS material above to determine whether any credit or deduction applies, such as for a 2025 install or a commercial project.

Leases, PPAs, and the business 48E credit

Third-party-owned systems are the main exception for homes. With a lease or a power purchase agreement (PPA), a company owns the equipment on your roof and sells you the power or rents you the system. That owner may still claim the business 48E credit through 2027, and part of that value can show up as a lower monthly price.

You do not own the system, so the contract matters more than the headline. Read the escalator, the buyout terms, what happens if you sell the house, and who pays to remove and reinstall the array if your roof needs replacing. That removal and reinstall typically costs $3,000 to $6,000 when it is time for a re-roof.

Tennessee and Nashville specific incentives, where to look

Tennessee does not currently offer a broad, simple statewide solar tax credit comparable to the old federal Residential Clean Energy Credit. Incentives in this state tend to be more targeted and often focus on commercial, industrial, or certified green energy production rather than typical residential rooftop systems.

The most reliable public catalog of Tennessee incentives is DSIRE, the Database of State Incentives for Renewables and Efficiency, maintained by the N C Clean Energy Technology Center. DSIRE lists state level programs, utility programs, and certain tax provisions and links them back to the underlying statutes and program pages.

When we work on projects in Franklin, Brentwood, Mt Juliet, Lebanon, La Vergne, Smyrna, or rural counties around Nashville, we recommend that owners and their advisors use DSIRE’s Tennessee pages as a starting point to identify any current incentives that might apply to a specific property type or county. DSIRE also points to Tennessee’s “green energy property” tax assessment language, which is aimed at certified green energy production facilities and has to be interpreted carefully for each site.

Because DSIRE is a reference index and not a tax authority, the information found there still has to be read through the lens of your accountant and, in some cases, your local assessor or attorney.

Commercial and rural incentives in Middle Tennessee

Businesses, churches, industrial facilities, and farms around Nashville have a broader set of tools, but they are also more technical. In Franklin, Brentwood, Mt Juliet, La Vergne, Lebanon, and surrounding areas, commercial projects often combine three elements:

The business 48E clean electricity credit, applied under commercial rules rather than residential rules. Projects that began construction after July 4, 2026 must be placed in service by December 31, 2027. Battery storage is not subject to that solar deadline.

Depreciation, including MACRS and any current bonus depreciation allowances, which can allow the cost of solar and storage assets to be written down more quickly on the business’s books.

Rural and agricultural grants, with a big caution. USDA REAP used to be the go-to program for farms and rural small businesses, but 2026 USDA rule changes sharply restricted solar eligibility and are being challenged in court. We never promise REAP funding.

For planning, commercial solar from 50 to 700+ kW runs about $2.20 to $3.00 per watt installed, before incentives.

On these projects our job is to clearly separate roof work, solar and battery scopes, and electrical upgrades, and to provide stamped drawings and cost breakdowns. The tax and grant analysis is handled by the client’s CPA, controller, lender, or outside consulting firm, using the IRS and program documents that apply.

TVA, NES, and MTE, policy context rather than direct “incentive”

Most of the Nashville region is served by NES, Middle Tennessee Electric, or a local co op under TVA. TVA has retired its legacy Green Power Providers buyback and does not offer traditional 1-for-1 net metering for residential rooftop solar. NES runs NESolar Connect and NESolar Savings, limited programs that buy eligible excess solar under specific terms and caps. TVA’s Dispersed Power Production program buys excess generation at TVA’s avoided cost, a wholesale style rate.

For a homeowner in East Nashville, Donelson, Franklin, Brentwood, Mt Juliet, Bellevue, or Gallatin, this means that “incentives” from the utility side are indirect. Solar primarily lowers your NES or MTE bill by reducing the number of kilowatt hours you purchase over the year, not by generating large retail credits for exported energy. Export programs, where they exist, generally resemble wholesale style arrangements more than classic net metering and are not the main driver for residential economics.

We design every residential system around that reality, self consumption first, and treat the commercial 48E credit, depreciation, and any limited utility programs as the main formal incentives that remain.

How The Solar Roofers handle incentives in your project

In our process, incentives are part of the planning, but they never replace basic engineering. For a home or small business in Nashville or Middle Tennessee, we first check roof age and structure, shade, and NES or MTE usage. We then design a roof, solar, and storage package that makes sense on its own terms, independent of any credit.

Once the technical design is defined, we price the project in clear sections. Roofing, solar equipment and installation, battery equipment and installation, and electrical upgrades are shown separately. That structure is deliberate. It gives your CPA the information needed to distinguish between energy property and other building work when preparing business energy credit schedules or depreciation, or when reviewing a lease or PPA.

At that point we expect you to bring your accountant into the conversation. They should confirm that the homeowner credit does not apply to a 2026 install and, for commercial or rural projects, review the current 48E and depreciation guidance, and then tell you what credit or deduction you can actually claim based on your situation. If they have technical questions about what was installed or how costs were allocated between roof and solar, we answer those from the construction side.

Only after that discussion do you commit to a final contract. That way the engineering, the construction price, and the tax treatment are aligned before crews set foot on your roof.

Important note about tax advice

The Solar Roofers and The Metal Roofers do not provide tax, legal, or accounting advice. Any tax credit, depreciation, grant, or incentive examples discussed here are general in nature and are based on publicly available IRS, DOE, and DSIRE summaries that may change over time.

Homeowners and businesses in Nashville and Middle Tennessee should consult their own CPA, tax preparer, or other qualified advisor to confirm current rules, eligibility, and the exact amount of any credit or deduction before making financial decisions. Our role is to design and build systems that work in this region and to provide clear documentation. Your advisor’s role is to interpret tax law for your specific situation.
