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 - Norris 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 Norris homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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.
If a salesperson in Norris tells you a 30% federal tax credit applies to your 2026 installation, they are quoting a dead law. What may still exist: South Carolina's own incentives and tax treatment, listed below, and lease/PPA arrangements where a company claims commercial credits - in which case the credit belongs to them, not you.

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 Norris 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 Norris quotes
Same-day contracts are a red flag in this industry. Legitimate SC installers expect you to compare bids, check licenses, and read the interconnection terms. Anyone pressuring you to sign at the kitchen table is pricing in your haste.

Common questions
Is solar still worth it without the federal credit?
It depends mostly on your state's export rules and your daytime usage. Paybacks lengthened by roughly a third when the credit ended, but rising electricity rates and record-cheap hardware keep the math workable in states with decent export compensation - and marginal where exports pay avoided cost only.
How do I check if a solar quote is fair?
Divide the total price by the system's wattage. The U.S. marketplace average is about $2.58 per watt installed; $2.30-3.00 covers most fair quotes depending on roof complexity. Above that, ask exactly what you are paying extra for - in writing.
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.
Does solar raise my property taxes?
It depends on the state - many exempt solar's added home value from property tax, others do not, and some exemptions have expiration dates. This guide's state page lists the verified rule and source for your state.
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.
