Solar incentives in Fort Mill, SC

Two things changed for Fort Mill in 2026: the 30% federal credit ended on December 31, 2025, and Duke Energy Carolinas moved new solar customers onto Duke's current residential solar rate structure. Here is what is actually left, and what it is worth on a real roof.

The short answer · as of July 2026

Fort Mill homeowners can claim South Carolina’s 25% state tax credit (Form TC-38), capped at $3,500 per tax year with a 10-year carry-forward, plus property-tax exemption on qualifying systems of 20 kW or less and sales-tax exemption on equipment. Duke Energy Carolinas credits exported power at roughly 2.6–4¢ per kWh under Duke's current residential solar rate structure. The 30% federal credit is no longer available.

Local incentive reality

The incentive picture in Fort Mill

Fort Mill sits on Duke Energy Carolinas with York Electric Cooperative serving many addresses, and the two credit exported power on different terms. Duke has run programmes in the Carolinas that have been at or near capacity, so treat any rebate line in a quote as a question rather than a number: name the programme, state its current status, and show what the price becomes without it.

The state credit does not vary: 25% of installed cost on Form TC-38, capped at $3,500 in a tax year, carried forward until used, with property-tax exemption on qualifying systems of 20 kW and under and sales-tax exemption on equipment. York County administers the property-tax side. Because Fort Mill houses are new and often large, that credit is typically claimed across several returns rather than one.

A caution particular to this market: it sits in the Charlotte commuter belt, and North Carolina's incentive position is not South Carolina's. If a salesperson has crossed the state line with their standard presentation, the incentive slide is one of the first things that will be wrong. Ask specifically which state's rules the numbers were built on, and check that Form TC-38 is the credit being described.

Written for Fort Mill specifically. Your own roof, bill and meter still decide the answer, which is what the free assessment settles.

Start here, it matters most

What Duke Energy Carolinas pays you for solar in Fort Mill

People search for incentives and mean tax credits. In Fort Mill the bigger lever is what your utility credits you for the power you send back, because that applies every month for 25 years rather than once at tax time.

Duke Energy Carolinas Duke's current residential solar rate structure terms for new residential solar in Fort Mill, as of July 2026. Confirm current terms with the utility before deciding.
Item Current position (July 2026)
ProgrammeDuke's current residential solar rate structure, which replaced one-for-one net metering for new residential systems from January 1, 2026
Retail rate you avoidyour full retail rate for power you use as you generate it
Export creditroughly 2.6–4¢ per kWh for power you send back, on a time-of-use basis
Monthly riderNone specific to this programme, though standard service charges still apply.
Annual true-upLeftover credits settle each November at an avoided-cost rate
Upfront utility rebateDuke's PowerPair solar-and-battery incentive has been at or near capacity in Carolinas territory, so it should not be assumed available. Duke's battery bill-credit programme has remained open and pays monthly rather than up front. We check live status for your address before it forms part of any number we give you.
Who confirms your territoryWe do, at the assessment. In and around Fort Mill, York Electric Cooperative serves many addresses here, and terms differ.

The practical consequence: a kilowatt-hour you use yourself is worth roughly three to five times a kilowatt-hour you export. That is why we size to your consumption rather than to your roof area, and why load shifting or storage now matters more in Fort Mill than it did two years ago.

Statewide rules

The parts that are the same everywhere in SC

Three incentives apply identically across South Carolina, so we explain them once rather than eighteen times. In short: a 25% state income tax credit on Form TC-38 capped at $3,500 per tax year with a 10-year carry-forward, property-tax exemption on qualifying systems of 20 kW or less, and sales-tax exemption on equipment. The 30% federal credit expired for systems placed in service on or after 1 January 2026.

The cap is the part that catches people out. Because you can only claim $3,500 a year, a system whose 25% credit is $6,000 arrives across two tax returns rather than as one payment, and low state tax liability stretches it further still.

Eligibility depends on your circumstances and none of this is tax advice, so confirm with a tax professional. Property-tax treatment is administered locally, see York County below.

York County

What the exemption is worth in York County

An eligible rooftop system of 20 kW or less should not increase your assessed value in York County, so you are not paying annually for an improvement that is reducing your power bill.

The exemption's cash value scales with local millage, so it is worth more in higher-millage jurisdictions. We do not publish a millage figure for York County without an auditor-current schedule on file, because a wrong number here is worse than no number. Your assessment walks through how the exemption works for your parcel instead.

The 20 kW threshold matters if you are considering a large system in Fort Mill. Sizing past it can cost you the exemption entirely, which is another reason right-sizing beats maximising, and another reason Duke Energy Carolinas's export rate of roughly 2.6–4¢ per kWh should shape the design.

Adding it up

Businesses

Incentives for Fort Mill businesses

Commercial solar is treated differently from residential. Federal commercial provisions and depreciation treatment may still apply where the residential credit does not, and the structuring genuinely matters.

We are installers, not tax advisers, so we will not model your commercial position for you. What we will do is scope and build the system, document it properly for your accountant, and route the tax questions to your CPA rather than guess at them.

Permits and approvals

What approval takes in Fort Mill

This is the part most quotes leave vague, and it is the part that decides how long a job takes. Below is what a system at a Fort Mill address actually has to clear. We handle all of it, and you file none of it yourself, but you should know what you are agreeing to a timeline for.

  1. 01A building permit and a separate electrical permit for a rooftop system
  2. 02Standard plan review for systems of roughly 10 kW and above
  3. 03A zoning review as well for any ground-mounted array
  4. 04An additional electrical permit where battery storage is included
  5. 05Structural review under York County requirements
  6. 06HOA architectural-review approval, which is common here and which we prepare
  7. 07Duke interconnection approval before the system is allowed to energise

Requirements are read from the authority that reviews your address, not assumed from the county. In SC that distinction is routinely the difference between a permit issued and a permit returned.

Fort Mill incentives FAQ

Common questions about solar incentives in Fort Mill

What solar incentives can I get in Fort Mill, SC in 2026?

South Carolina offers a 25% state income tax credit on Form TC-38, capped at $3,500 in any one tax year and at 50% of your annual state liability, with a ten-year carry-forward. Qualifying residential systems of 20 kW or less are exempt from South Carolina property tax. Solar equipment is exempt from South Carolina state sales tax. The 30% federal credit expired for systems placed in service on or after January 1, 2026.

Does Fort Mill still have net metering?

Not in the original form. One-for-one net metering closed to new applicants in South Carolina before the current programme took over, and new customers are enrolled in Duke's current residential solar rate structure instead. Under that programme exported power is credited at roughly 2.6–4¢ per kWh rather than at the your full retail rate retail rate, and settled against your usage over the year.

How do I claim South Carolina’s 25% state tax credit?

You claim it on South Carolina Form TC-38 with your state income tax return for the year the system is placed in service. Because the credit is capped at $3,500 per year and at 50% of your state tax liability, most systems are claimed across two or three returns using the 10-year carry-forward. Keep your final invoice and commissioning documentation. Confirm your own eligibility with a tax professional.

Is there a Duke Energy Carolinas rebate for solar in Fort Mill?

Duke's PowerPair solar-and-battery incentive has been at or near capacity in Carolinas territory, so it should not be assumed available. Duke's battery bill-credit programme has remained open and pays monthly rather than up front. We check live status for your address before it forms part of any number we give you.

Will solar panels increase my property taxes in Fort Mill?

Qualifying residential systems of 20 kW or less are exempt from South Carolina property tax. Confirm your own position with York County and a tax professional, since eligibility depends on your circumstances.

Are there solar incentives for Fort Mill businesses?

Commercial solar is treated differently from residential and federal commercial provisions such as 48E and depreciation may still apply. We do not give tax advice on commercial structuring, and we will route those questions to your CPA rather than guess. See our commercial solar page for how we scope the work itself.
