Solar incentives in Florence, SC
Two things changed for Florence in 2026: the 30% federal credit ended on December 31, 2025, and Duke Energy Progress 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
Florence 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 Progress 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 Florence
Florence sits in Duke Energy Progress territory, with Pee Dee Electric Cooperative and other cooperatives serving surrounding addresses. Duke has run incentive programmes in the Carolinas that have been at or near capacity, so the question to ask about any rebate in a quote is not whether the programme exists but whether you are actually going to receive it, and what happens to your price if you do not.
The state credit is the dependable part: 25% of installed cost on Form TC-38, capped at $3,500 in a tax year, carried forward, plus property-tax exemption on qualifying systems of 20 kW or under and sales-tax exemption on equipment. Florence County administers the property-tax side. Those apply regardless of which utility serves you, which makes them the stable floor under any projection.
Because Duke credits exported power at roughly 2.6 to 4 cents against your full retail rate, the incentive that matters most in Florence is arguably not an incentive at all. It is sizing the system so you consume what you generate. The credit reduces the capital cost of a well-sized system by a quarter; it does nothing to rescue an oversized one built to export power at a few cents.
Written for Florence 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 Progress pays you for solar in Florence
People search for incentives and mean tax credits. In Florence 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.
| Item | Current position (July 2026) |
|---|---|
| Programme | Duke's current residential solar rate structure, which replaced one-for-one net metering for new residential systems from January 1, 2026 |
| Retail rate you avoid | your full retail rate for power you use as you generate it |
| Export credit | roughly 2.6–4¢ per kWh for power you send back, on a time-of-use basis |
| Monthly rider | None specific to this programme, though standard service charges still apply. |
| Annual true-up | Leftover credits settle each November at an avoided-cost rate |
| Upfront utility rebate | Duke's PowerPair solar-and-battery incentive closed to new applications in Progress territory in late 2025, so it should not be counted on here. Duke's battery bill-credit programme has remained open and pays a monthly credit rather than cash up front. We confirm current status for your address rather than promising a programme that may be full. |
| Who confirms your territory | We do, at the assessment. In and around Florence, Pee Dee Electric Cooperative and other cooperatives serve surrounding addresses, 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 Florence than it did two years ago.

Duke's PowerPair solar-and-battery incentive closed to new applications in Progress territory in late 2025, so it should not be counted on here.

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 Florence County below.
Florence County
What the exemption is worth in Florence County
An eligible rooftop system of 20 kW or less should not increase your assessed value in Florence 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 Florence 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 Florence. Sizing past it can cost you the exemption entirely, which is another reason right-sizing beats maximising, and another reason Duke Energy Progress's export rate of roughly 2.6–4¢ per kWh should shape the design.
Adding it up
What a Florence homeowner actually nets in 2026
An illustrative stack on a 9.5 kW system at the local benchmark. An example to show the shape of it, not a quote and not a promise.
| Line | Amount |
|---|---|
| 9.5 kW system at $2.59 per watt | $24,605 |
| State sales tax | Exempt |
| Federal credit | $0, expired for 2026 installs |
| Duke Energy Progress rebate | See above |
| SC 25% credit (TC-38) | −$6,033, claimed across 2 tax years |
| Net cost | about $18,454 |
| Annual property tax added | $0 on qualifying systems ≤20 kW |
For what that net figure means as a payback period, and why the answer depends far more on when you use power than on which panels you buy, see solar panel cost in Florence.
Businesses
Incentives for Florence 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.

Florence incentives FAQ
Common questions about solar incentives in Florence
What solar incentives can I get in Florence, SC in 2026?
South Carolina's 25% state income tax credit (Form TC-38) is the main one, worth 25% of installed cost, capped at $3,500 per tax year with a 10-year carry-forward. Qualifying systems of 20 kW or less are also exempt from property tax, and solar equipment is exempt from state sales tax. The 30% federal credit expired for systems placed in service on or after January 1, 2026.
Does Florence still have net metering?
Not in the original form. Duke Energy Progress's one-for-one net metering closed to new residential systems on December 31, 2025, 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% solar 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 Progress rebate for solar in Florence?
Duke's PowerPair solar-and-battery incentive closed to new applications in Progress territory in late 2025, so it should not be counted on here. Duke's battery bill-credit programme has remained open and pays a monthly credit rather than cash up front. We confirm current status for your address rather than promising a programme that may be full.
Will solar panels increase my property taxes in Florence?
South Carolina exempts qualifying residential renewable energy systems of 20 kW or less from property tax, so an eligible rooftop system should not raise your assessed value. Confirm your own position with Florence County and a tax professional, since eligibility depends on your circumstances.
Are there solar incentives for Florence 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.
