What South Carolina still offers after the federal credit ended
Every incentive on this page is verified against South Carolina government sources - and the expired ones salespeople still quote are called out.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Pendleton systems completed in 2026 get $0 from it.
Under South Carolina's export rules, compensation for surplus power decides the payback - which typically runs 10-14 years on unsubsidized 2026 math.
Installed home solar for Pendleton homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Leased and PPA systems deserve extra scrutiny in 2026: the sales pitch often bundles 'tax savings' that now accrue to the leasing company under separate commercial rules - not to you. Get every claimed saving in writing, attributed to a specific law, before signing a 20-25 year contract.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, it is not available for any system placed in service after December 31, 2025, and 'placed in service' means the installation completion date, not the contract date.
The 2026 numbers

South Carolina rules that decide your payback
| Rule | South Carolina status |
|---|---|
| Export compensation (net metering) | Not full retail for new customers — the 1:1 Renewable Net Metering rider (Rider RNM) closed to new participants on June 1, 2021, and new residential solar now takes Solar Choice Metering (Rider RSC, served on a solar time-of-use schedule), while the last full-retail legacy class (applications before May 16, 2019) reached its sunset on December 31, 2025 and moves to Rider NMT or Rider RSC. |
| State incentive | Solar Energy, Small Hydropower System, or Geothermal Machinery and Equipment Credit (S.C. Code Ann. Section 12-6-3587) — 25% of purchase and installation cost, capped at $3,500 per facility or 50% of tax liability per year, whichever is less, with a 10-year carryforward |
| Sales tax on the system | Not exempt - taxed like any purchase |
| Property tax on added home value | Excluded |
South Carolina still has a live 25% state income tax credit — genuinely unusual for this region — but the old full-retail net metering grandfather class expired on December 31, 2025, so a 2026 install earns markedly less for exports than a 2019 install did. Note also that the South Carolina property tax exemption is capped at 20 kW AC: systems above that size do not qualify, though attached battery storage is included within the exemption.

What this means for Pendleton roofs
Whether solar still pays in South Carolina after the federal credit's end comes down to arithmetic, not ideology: installed cost (about $2.58 a watt at the marketplace average), what your utility pays for exports, and how much of your generation you use yourself. High self-consumption - daytime usage, EV charging, batteries - is now the biggest lever.

Getting Pendleton quotes
The spread between the highest and lowest bid for the same roof routinely hits 30-50%, because solar quotes carry very different sales overheads. Two or three independent bids collected against the same system size is the single highest-value hour in the whole project.

Common questions
Is my roof even suitable for solar?
Three things decide it: orientation (south-facing is best in the U.S., east-west workable), shade (trees or taller buildings across midday hours can sink the math), and roof age (if the shingles have under 10 years left, reroof first - removing and reinstalling panels later costs thousands). Any honest installer assesses all three before quoting a number.
How long do solar panels actually last?
Panels are typically warrantied for 25 years of production and commonly outlive it, losing about 0.5% output per year. Inverters are the component that usually needs replacement - typically once, around year 12-15, at a few thousand dollars.
Should I lease, get a PPA, or buy?
Buying keeps all savings and any incentives with you. Leases and PPAs put a company's equipment on your roof for 20-25 years, complicate a home sale, and in 2026 any tax benefits they advertise belong to the company under commercial rules - not to you. Read escalator clauses carefully.
Do I need a battery with my solar?
Not necessarily. Under full retail net metering, the grid effectively stores your surplus for free. Batteries earn their $12,000-16,000 price where export rates are low, outages are common, or time-of-use rates make evening self-consumption valuable.
What happens if my installer goes out of business?
Panel and inverter warranties come from the manufacturers and survive, but the workmanship warranty usually dies with the company. That is a real risk in the post-credit shakeout - prefer installers with years of local history, and get manufacturer-backed workmanship coverage where offered.
