Straight Answer First

The 2026 Answer: Homeowners Lost the Credit, Businesses Have a Deadline

Here is the straight answer for 2026. Tennessee homeowners can no longer claim the 30% federal solar tax credit: the Section 25D credit ended for systems installed after December 31, 2025, and that includes home batteries. Businesses, farms, churches and the owners of leased systems can still use the Section 48E credit, but solar projects that began construction after July 4, 2026 must be placed in service by December 31, 2027, and battery storage is not held to that deadline. USDA REAP grants are sharply restricted for solar, and Tennessee has no traditional net metering, so NES and the other TVA power companies buy excess solar only through limited programs. The Solar Roofers, a family-owned solar and roofing company in Nashville, prices every system on what it saves first, then works with your CPA on whatever credits apply. Confirm every credit and deadline with a tax professional.

Federal and Farm Incentives

Federal and Farm Solar Incentives in 2026, Line by Line

USDA REAP Grants: Sharply Restricted for Solar in 2026

REAP, the Rural Energy for America Program, was the go-to grant for Tennessee farms and rural small businesses adding solar. Not anymore.

‍What Changed
Starting in August 2025, USDA capped ground-mounted solar at 50 kW, tightened eligibility for projects on cropland and projects without documented energy use, barred solar panels made by foreign adversaries, and paused new grant applications. In 2026 USDA moved to formalize those limits and applied them to some applications that were already filed.

‍Where It Stands
Farm and solar groups sued USDA in federal court in Washington, D.C. in September 2026. Until that is settled, REAP is not a dependable source of money for solar.

‍Our Advice
We will not promise REAP funding. Build the project so it works without a grant and treat any award as a bonus. USDA program page: https://www.rd.usda.gov/inflation-reduction-act/rural-energy-america-program-reap

Section 48E Business Credit: Still Here, on a Deadline

Businesses, farms, churches and other commercial owners can still claim the federal clean electricity investment credit under Section 48E in 2026. The clock is the catch.

The Deadline

Under the One Big Beautiful Bill Act, signed July 4, 2025, solar projects that began construction after July 4, 2026 must be placed in service by December 31, 2027. IRS Notice 2025-42 sets the rules for when construction counts as started. Battery storage is not subject to that solar deadline.

‍The Rate
The base credit is 6% and rises to 30% for projects that meet prevailing wage and apprenticeship rules; projects under 1 MW generally qualify for the full rate without them. Churches, nonprofits and local governments can use elective pay. Confirm your rate and your dates with a tax professional.

‍Homeowners
This is a business credit. The 25D homeowner credit ended for systems installed after December 31, 2025. IRS overview: IRS Clean Electricity Investment Credit

Depreciation for Business-Owned Solar

IRS webpage titled Publication 946 (2023), How To Depreciate Property, listing sections like Future Developments and What's New for 2023.
A business that owns its solar system can depreciate it, which lowers taxable income on top of any credit.

‍What Changed in 2025
The 2025 tax law made 100% bonus depreciation permanent for qualifying property acquired after January 19, 2025, and it also changed the old 5-year MACRS treatment for some energy property. A first-year depreciation number from an older brochure may be wrong for your project.

‍Who Sets the Schedule
Your CPA does. We supply a cost breakdown that separates roof work, solar equipment, batteries and electrical so each piece can be classified correctly. Homeowners cannot depreciate a system on their own home.

Energy Community Bonus Credit

Section 48E projects located in a federally designated energy community can qualify for a larger credit. The U.S. Department of Energy publishes a map of the qualifying areas.

‍How the Map Works

Coal Closure Areas
: Census tracts where a coal mine or coal-fired power plant has closed, and the tracts next to them, can qualify.

‍Employment-Based Areas: Some metro and non-metro areas tied to fossil fuel jobs and higher unemployment also qualify, and that list is updated each year.

‍The Catch: The bonus only matters if the project still qualifies for 48E, so commercial solar still has to meet the 2026 and 2027 deadlines.

‍What We Do: We check your site address against the current map during design and note the result for your CPA.

Home Solar Math in 2026

Paying for Home Solar Without the Federal Credit

Without the 30% homeowner credit, home solar in Nashville has to stand on its own savings. A typical 8 to 14 kW home system runs $22,800 – $49,000 installed and makes about 11,000 to 19,000 kWh a year, against the average Nashville household's use of about 1,075 kWh a month.

Homeowners pay for solar with cash, a solar or home-improvement loan, or a lease where a company owns the equipment. Our solar financing page walks through how each one works in 2026.

Shop a solar loan like any other loan: compare the rate, the term, any dealer fee folded into the price, and whether it is secured by your home.

Those totals assume rates never rise, so treat them as the floor. At the Nashville average of about $134 a month, that is roughly $16,080 over 10 years and $40,200 over 25 years, which is the money a solar system competes with.

Who Gets What in 2026

What the 2026 Rules Mean for Homeowners, Businesses and Farms

✦ ✦ ✦

Homeowners: the 30% federal solar credit ended on December 31, 2025.

If you own a home in Davidson, Williamson or Rutherford County and buy a solar or battery system in 2026, there is no federal tax credit to claim. The Section 25D credit ended for systems installed after December 31, 2025, and it covered home batteries too. Here is what still matters for a homeowner:

  • Leases are the exception. The company that owns a leased system may still claim the business credit on systems placed in service by the end of 2027, so ask how much of it shows up in your price.
  • Savings carry the math now. An 8 kW array runs about $22,800 – $28,000 installed and makes roughly 10,800 to 11,600 kWh a year, close to a full year of use for an average Nashville household.
  • Old quotes are wrong. Any 2026 proposal that subtracts 30% from a homeowner's price is using a credit that no longer exists.

When we design a system for a home in Donelson, Hermitage or Madison, the proposal shows the installed price, the expected production for Nashville's roughly 4.8 peak sun hours a day, and the bill offset against your own 12 months of usage. No phantom credits.

For homeowners, the numbers now rest on your power bill, not on a tax credit.

Businesses and farms: Section 48E still applies, on a deadline.

Offices in Green Hills, shops in 12 South, warehouses in La Vergne and farms outside Gallatin can still use federal incentives in 2026. For a business, the stack usually looks like this:

  • The Section 48E investment credit, for solar that began construction by July 4, 2026 or is placed in service by December 31, 2027.
  • Depreciation on the business-owned equipment, on a schedule your CPA confirms.
  • Battery storage under 48E, which is not held to the 2027 solar deadline.

All of that sits on top of your real operating costs: demand charges, peak windows and rate changes from NES, Middle Tennessee Electric or your local TVA power company. For a Franklin church, a Brentwood medical office or a Lebanon light-industrial building, we treat roof, solar and incentives as one capital project that your CPA, banker and board can all follow.

Farms and rural businesses: do not build the budget around a grant.

Outside Metro Nashville, a lot of properties are part home, part farm and part business. A cattle operation in Wilson County, a greenhouse in Robertson County or a food producer outside Murfreesboro used to plan solar around a USDA REAP grant. In 2026 that grant is sharply restricted for solar and tied up in court.

What still works for a farm project:

  • A solar array sized around real loads: well pumps, coolers, barns, shops and the house itself.
  • The Section 48E credit and depreciation for the farm business, on the 2027 schedule.
  • Farm credit, bank or equipment financing, or the state's Tennessee Energy Efficiency Loan Program, with a REAP application treated as a possible bonus, never the plan.

We design the roof and the solar with clean, auditable scopes of work, so your banker, your CPA and any grant reviewer all work from one set of drawings and numbers.

TVA and NES rules decide what your extra power is worth.

Nashville is TVA territory. NES, Middle Tennessee Electric and the surrounding co-ops all operate under TVA rules, and that matters because:

  • There is no traditional 1-for-1 net metering, and TVA retired its old Green Power Providers buyback.
  • NES buys eligible excess solar through NESolar Savings, for systems under 250 kW with an average monthly surplus of at least 50 kWh, and NESolar Connect, which buys all the output of systems larger than 200 kW. Both run under specific terms and caps.
  • Efficiency programs for HVAC, insulation and other upgrades can sit alongside solar, even though they are not solar incentives by name.

So we size systems for self-consumption and outage protection, not for export. Every proposal we build for an East Nashville bungalow, a Belle Meade estate or a Bellevue ranch is modeled on current TVA and NES rules and your real bills, not on net metering from another state.

Roof, solar and battery work best as one project.

The Solar Roofers handles roofing and solar under one roof, so we design the roof and the solar together. That matters for your money:

  • Doing roof and solar as one project typically saves $2,000 – $5,000 in shared permits, wiring, crew and scaffolding.
  • Roof, structural, solar and electrical costs are broken out so your CPA can classify each one.
  • You avoid paying $3,000 – $6,000 to remove and reinstall an array when an old roof gives out a few years later.

For a homeowner in Donelson or Franklin, that can mean a new standing seam metal roof, where panels clamp to the seams with no roof penetrations, plus a right-sized array and a battery. For a commercial building in Antioch or a campus in Hendersonville, it can mean phasing roof, solar and electrical work so the solar is in service before the end of 2027.

‍

A good installer explains incentives without pretending to be your CPA.

You should not have to research tax law on your own, and you should not take tax advice from a sales script. Here is how we handle it:

  • We track the federal, TVA and NES rules that affect Middle Tennessee projects and update our proposals when they change.
  • We write proposals with clean cost breakdowns, equipment lists and schedules your tax professional can use.
  • We tell every client, homeowner or business, to confirm credits, deadlines and depreciation with a CPA before signing.

During design we show payback on realistic Nashville production, about 1,350 to 1,450 kWh per kW of panels a year, against your own bills. Then we hand you and your CPA the paperwork.

‍

48E, REAP and Elective Pay

Does your Tennessee solar or battery project qualify for Section 48E?

Start with the owner, equipment and dates, not a promised percentage. A commercial quote should separate the installed price from any tax benefit. Use this screening checklist with your tax adviser before a contract, then update it before filing. Sources checked October 29, 2026. General education, not a determination of eligibility.

  1. Identify the tax owner and use. Record the legal entity, who buys and owns the equipment, business versus personal use, and the proposed claimant. A homeowner does not obtain a business credit simply because an installer calls a system commercial. Ask your adviser to classify the arrangement before comparing ownership with a lease.
  2. Separate solar from storage. For applicable solar facilities beginning construction after July 4, 2026, the credit ends if placed in service after December 31, 2027. Storage is excluded from this particular solar termination rule, but still has its own eligibility requirements. A signed proposal or equipment deposit alone does not settle the tax construction-start date. IRS Notice 2025-42, sections 1–6.
  3. Document the increased-rate route. The base 48E rate is 6%; the increased rate generally requires prevailing-wage and apprenticeship compliance or an exception. A qualified generation facility with maximum net output below 1 MW AC, or storage with capacity below 1 MW, has an increased-rate exception. Capacity and aggregation need professional review; do not substitute panel DC nameplate for the applicable test. IRS Form 3468 instructions, increased-credit requirements.
  4. Keep two size tests separate. Notice 2025-42's limited five-percent construction safe harbor for qualifying low-output solar uses a maximum of 1.5 MW AC. That is a different rule from the less-than-1-MW increased-credit exception. Neither test means every project below that size automatically qualifies. Notice 2025-42, section 6.
  5. Check equipment sourcing before procurement. Material assistance from prohibited foreign entities can disqualify covered solar or storage whose construction begins after December 31, 2025. Notice 2026-15 supplies interim cost-ratio and safe-harbor guidance. A brand name, assembly location or “made in America” sales phrase is not a substitute for the required analysis. Request supplier documentation and have your adviser review its sufficiency. IRS Notice 2026-15.
  6. Approve bonuses separately. Ask the adviser to sign off on each claimed domestic-content, energy-community or allocated low-income bonus, rather than adding every possible bonus to the base quote. Record the qualifying facts, applicable dates and supporting determination. Review current Form 3468 instructions.

The handoff folder your CPA needs

Keep one version-controlled folder containing ownership documents, cost allocations, invoices and proof of payment, equipment and supplier records, construction-start evidence, permits, commissioning records, capacity calculations, labor-compliance records where applicable, and each proposed bonus determination. Ask the CPA which facts establish placed-in-service status; an invoice date is not enough evidence by itself.

Use three budget columns: contract price before incentives, tax benefits approved by the adviser, and benefits still unverified. Put unverified benefits at zero in the financing stress test. See the financing comparison worksheet and nonprofit elective-pay checklist.

REAP for Tennessee farms and rural businesses: October 2026 rules

Do not subtract an assumed REAP grant from a solar contract. As checked October 29, 2026, USDA says it is not accepting REAP grant applications; guaranteed-loan applications may be submitted. A loan guarantee supports qualifying lending and is not a grant paid to the owner. Start with the Tennessee program official and the current application notice. USDA application status and contacts.

What changed October 16, 2026?

The October 1 final rule, effective October 16, changes the grant pathway to completed, performance-documented projects. It requires at least 75% cost sharing, with renewable-energy grant requests capped at $500,000. Project-period completion generally must fall 12–24 months before application; the first window permits 12–36 months. Applicants provide pre-installation and post-installation energy records covering 12 months. Ground-mounted solar on cropland is ineligible, and component-origin restrictions also apply. These are screening points, not the complete eligibility test. Final rule, §§4280.121–125 and 4280.131.

A practical planning sequence

  1. Ask USDA to confirm the applicable pathway. State the entity, site, intended ownership, project type and whether you seek a grant, guaranteed loan or both. Request the current notice and treatment of any already-filed application in writing.
  2. Screen the site before paying for design. Bring the parcel map, land-use history, proposed array footprint and equipment list. Do not assume a rural mailing address or a farm name proves eligibility.
  3. Build a no-grant budget. Identify who pays design, construction, debt service and operating costs while the project operates and an application is evaluated. Include a delayed-award and no-award scenario.
  4. Preserve evidence from the beginning. Keep baseline utility records, interval data where available, separate production-meter records, bills, invoices, payment evidence, commissioning files and dated equipment specifications. Reconcile missing or estimated meter intervals before relying on them.
  5. Recheck before applying. Have USDA confirm the live window, applicable project dates, supporting records and ownership requirements. Reconcile the requested award with your CPA's treatment of other funding.

Budget rule: an eligible project is not a promised award. The working cash plan should stand without a grant; any later award needs its own approval and accounting. Keep the 48E tax-credit analysis separate from the USDA application.

How a Tennessee church or nonprofit plans for elective pay

Elective pay can make an eligible clean-energy credit refundable, but it is not an installer rebate at signing. The organization must qualify, the project must earn an eligible credit, and the entity must complete registration and filing. Certain projects face domestic-content-related payment reductions unless an exception applies. Check the IRS elective-pay overview. Sources checked October 29, 2026; obtain project-specific tax advice.

The IRS requires ownership of the credit property for this type of claim. Its process includes pre-filing registration and a valid election on a timely original return, with applicable extensions. An entity that normally files no annual income-tax return generally uses Form 990-T with the required credit forms and Form 3800. Payment generally follows processing; plan for uncertainty rather than treating a projected date as cash in hand. IRS elective-pay FAQ, Q11, Q19–25 and Q28.

Illustrative cash-flow exercise, not a church project or tax estimate

Suppose a board approves a hypothetical $100,000 installed project. If its adviser independently confirms a $30,000 eligible payment, the organization still needs a plan to cover the full $100,000 construction obligation before that payment arrives. The arithmetic is $100,000 minus $30,000 equals $70,000 after payment, before financing and operating costs. If the payment is delayed, reduced or unavailable, the construction obligation does not shrink. This example assumes the credit amount solely to show timing; it does not establish a 30% entitlement.

Questions to resolve before the board votes

  • Which entity owns the roof, which owns the solar equipment and which signs the utility agreement?
  • Who confirms the credit and files the return, and what is their scope of work?
  • Can the project proceed without using restricted donations improperly or exhausting operating reserves?
  • What happens to the cash plan if payment takes longer than expected?
  • Who keeps ownership, maintenance and tax records when board members or staff change?

For financing comparison, use cash versus financed total-cost math. For utility economics, use the Tennessee solar billing guide. Neither a utility estimate nor a contractor proposal substitutes for tax approval.

Commercial and Farm Projects

Planning a Commercial or Farm Solar Project in 2026: Three Steps

✦ ✦ ✦

With REAP grants restricted and the 48E clock running, the order of the work matters more than the paperwork.

Icon of dollars
Confirm the project's incentive lane and its deadline before anything else.

We start with what you are building: a shop in La Vergne adding rooftop solar, a cattle farm in Wilson County putting in a ground mount, or a food producer outside Gallatin tying solar into cold storage. Location, utility, ownership and load profile decide which incentives are realistic. For commercial solar in 2026 the first question is simple: can this system be placed in service by December 31, 2027? If the answer is no, we talk about battery storage, phasing or a different plan before you spend money on design.

Icon of a money bag and a contract behind it
Build the design package from real NES, MTE or co-op bills.

We pull 12 to 24 months of power bills and break out how your operation uses power by season. Then we design the roof and solar system, plus batteries if needed, around that usage: array size, inverter layout, mounting, structure and single-line diagrams. A greenhouse outside Murfreesboro means fans, pumps and winter heat. A cattle operation in Robertson or Wilson County means well pumps, barns and cold storage. A warehouse in Mt. Juliet means lighting, dock equipment and HVAC. You get production estimates for our climate and cost breakdowns that separate roof, solar, batteries and electrical, so your CPA, your lender and any grant reviewer read the same numbers.

Icon of a calendar
Line up tax, financing and construction so the system is in service on time.

Your CPA maps the credit and the depreciation. Your lender lines up the financing. We hold the schedule. Permits and utility interconnection take weeks on a home and can take longer on a large commercial system, so we start that paperwork early and phase the install around planting and harvest or production shutdowns. The goal is a system that is built, inspected and turned on inside the 48E window, not one that is approved on paper and late in the field.

Your Industry Can Benefit from Solar

✦ ✦ ✦

Solar Benefits for Agriculture

Farms and agricultural operations around Middle Tennessee can use solar to power wells, irrigation, barns, cold storage, and processing facilities on their own land instead of relying only on the grid. On cattle farms in Wilson County, row-crop operations near Springfield, or greenhouses outside Murfreesboro, daytime solar production lines up well with pumps, fans, lights, and equipment that already run hardest in the sun.

Because we’re in TVA territory, solar is usually about cutting the amount of power you buy each month, not selling a lot of extra back. That works well for farms that have steady daytime loads and rising electric bills. A farm-owned commercial project may still qualify for the business 48E credit if it meets the 2026 construction and placed-in-service rules, but do not count on USDA REAP grants: 2026 USDA rule changes sharply restricted solar eligibility and are being challenged in court. Our job is to size the system around your real NES, MTE, or co-op usage and give your lender and CPA clean paperwork so the project fits your farm’s long-term plan.

Architecture, Engineering & Construction

Architecture, engineering, and construction firms across Nashville tend to run heavy office and shop loads during daylight hours, exactly when solar produces. Design studios in Germantown and The Gulch, survey and engineering offices in Brentwood, and contractor shops in La Vergne or Lebanon all spend real money cooling open offices, powering computers and plotters, and lighting big spaces.

Solar lets those daytime kWh come from your roof instead of only from NES or MTE, smoothing long-term operating costs on buildings you plan to occupy for years. For contractors with warehouses or fabrication shops, large, low-slope roofs are often ideal solar real estate, and batteries can keep core systems and small tools powered when storms knock out the grid. Because we handle both the roofing and the solar, we can address roof age, penetrations, and future reroofing in the same plan, so you are not sending crews back up to pull arrays off a worn-out roof halfway through their life.

Solar Solutions for Auto Dealerships

Auto dealerships in Middle Tennessee are perfect candidates for solar because their biggest loads, showroom lighting, lot lights, shop equipment, and HVAC, are concentrated in long daylight hours and early evening. Stores on Murfreesboro Pike, Rivergate, Cool Springs, and along I-65 often have wide metal or membrane roofs and large car lots that see direct sun all day.

Solar can cover a meaningful portion of that daytime usage and take some of the sting out of lighting and cooling big glass showrooms. For dealerships leaning into EVs, rooftop or carport solar can pair with chargers so some of your charging load is supplied on site. Batteries can keep service-lane computers, network gear, and security systems running during NES or MTE outages without the noise and fuel of a generator. We design around your actual usage data and coordinate with your roofer, or handle the roof ourselves, so attachments, penetrations, and future reroofs are all accounted for before the first panel goes up.

Healthcare & Hospitality

Healthcare and hospitality properties in and around Nashville, medical offices, dental practices, surgery centers, hotels, and assisted-living facilities, have steady, non-negotiable power needs. Air conditioning, ventilation, medical equipment, laundry, kitchen loads, and 24/7 lighting all add up on NES and MTE bills in places like Midtown, Green Hills, Hendersonville, and Franklin.

Solar helps by taking a predictable share of those daytime kWh off the utility bill every month, year after year. Batteries add another layer: they can keep priority loads running during storms and outages, refrigeration for medications, critical IT, essential lighting, and certain HVAC or mini-split zones, without relying entirely on fuel-based generators. We design systems to work within healthcare regulations and hotel operating realities, and because we handle roofing as well, we can integrate the array into existing roof management plans instead of treating it as a separate, one-off project.

Cost Savings For Local Businesses

Local businesses across Nashville, from restaurants in East Nashville and Sylvan Park to salons, coffee shops, breweries, and small offices in Franklin, Mt. Juliet, and Gallatin, face the same problem: energy costs that never seem to move down. Most of those businesses use the bulk of their power during the day and early evening, which lines up well with solar production.

A right-sized system won’t erase your NES or MTE bill, but it can carve out a steady portion of your monthly usage and help insulate you from future rate increases. For owners who also own their building, solar becomes a long-term improvement to the property itself, not just a line item on the P&L. Batteries can keep key circuits alive during outages, POS systems, refrigeration, Wi-Fi, lighting, so you can stay open or at least protect inventory when the grid drops. We build systems around real meter data and roof conditions, so the array, the roof, and your business plan all line up.

Manufacturing, Distribution & Storage

Manufacturing plants, distribution centers, and warehouses in Middle Tennessee, especially along the I-24 and I-40 corridors in La Vergne, Smyrna, Lebanon, and Mt. Juliet, often have exactly what solar needs: large, unobstructed roofs and significant daytime electric bills. Process loads, conveyors, forklifts, lighting, compressors, and HVAC all add up to steady kWh consumption under TVA-based tariffs.

Solar can shoulder a substantial share of that daytime load and help reduce exposure to rising energy costs and certain demand-related charges, all while turning idle roof space into a productive asset. Cold storage and temperature-controlled warehouses benefit from pairing solar with carefully designed battery systems that can ride through short NES or co-op outages and support critical circuits. Because these facilities treat their roofs as critical infrastructure, our roofing background matters: we evaluate deck, membrane or metal condition, penetrations, and future reroofing plans so the solar investment and the roof life cycle are managed together, not in conflict.

Before You Sign

What to Verify Before You Sign a Solar Contract in Tennessee

✦ ✦ ✦

Six checks that keep a 2024 sales pitch out of a 2026 tax year.

Check 1

Who owns the system?

Owners claim credits. A homeowner who buys a system in 2026 has no federal credit to claim, and with a lease the leasing company claims it. Get ownership in writing.

Check 2

Which credit does the quote assume?

Any 2026 proposal that subtracts 30% from a homeowner's price is wrong. A business proposal should name Section 48E and the credit rate it assumes.

Check 3

When will it be placed in service?

Commercial solar that began construction after July 4, 2026 must be placed in service by December 31, 2027. Get the schedule, including utility interconnection, in writing.

Check 4

Where is the equipment made?

New foreign-entity sourcing rules apply to many 48E projects, and USDA bars panels made by foreign adversaries in REAP projects. Ask for the make and origin of the panels, inverters and batteries.

Check 5

Is the roof ready for 25 years?

Removing and reinstalling an array for a later re-roof typically costs $3,000 – $6,000. If the roof has only a few years left, plan the roof first.

Check 6

What will the utility and the county do?

There is no 1-for-1 net metering here and NES buyback runs through limited programs, so tie any savings figure to your real 12 months of bills. Ask your county assessor how the system will be treated for property tax.

Tax Credit Questions

Solar Tax Credit Questions We Hear in Nashville

✦ ✦ ✦

Can Tennessee homeowners still get the 30% solar tax credit in 2026?

No. The Section 25D residential clean energy credit ended for systems installed after December 31, 2025, under the One Big Beautiful Bill Act signed July 4, 2025, and that includes home batteries. With a lease, the company that owns the system may still claim the business credit, so ask how much of it is reflected in your price.

Can my Nashville business still claim the federal solar tax credit?

Yes, through the Section 48E credit, but on a deadline. Solar projects that began construction after July 4, 2026 must be placed in service by December 31, 2027, while battery storage is not subject to that solar deadline. Confirm your eligibility, credit rate and dates with a tax professional.

Is USDA REAP grant money still available for solar on Tennessee farms?

Not in a way you should count on. USDA restricted solar in REAP starting in 2025, including a 50 kW cap on ground-mounted systems and limits on cropland projects and foreign-made panels, and farm and solar groups sued over the changes in September 2026. We do not promise REAP funding; if a grant comes through, treat it as a bonus.

Does NES pay me for extra solar power?

Only through limited programs. NESolar Savings buys excess energy from systems under 250 kW with an average monthly surplus of at least 50 kWh, and NESolar Connect buys all the output of systems larger than 200 kW, both under specific terms and caps. There is no traditional 1-for-1 net metering in TVA territory, so we size systems for self-consumption.

What should I check before signing a solar contract that promises tax savings?

Check who owns the system, which credit the price assumes, and the date the system will be placed in service. Get the cost breakdown in writing for your CPA, and get any promise about credits, grants or buyback rates written into the contract. If anyone still quotes a 30% homeowner credit in 2026, walk away.
