Is there still a solar tax credit for Whitmire homeowners in 2026?
The 30% federal credit is gone for 2026 installations. What survives for Whitmire: South Carolina's own incentives and tax treatment - verified against state sources.
The 30% federal solar tax credit ended for installations finished after December 31, 2025 - Whitmire systems completed in 2026 get $0 from it.
Installed home solar for Whitmire homeowners averages about $2.58 a watt across the U.S. marketplace - roughly $30,960 for a 12 kW system before incentives.
Whitmire, South Carolina has about 1,439 residents, and its solar quotes are built from system size, roof complexity and export rules - not the town name.
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The federal Residential Clean Energy Credit - the 30% one every solar ad still quotes - was repealed by the One Big Beautiful Bill Act signed July 4, 2025.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The federal Residential Clean Energy Credit (30%) was repealed by the One Big Beautiful Bill Act signed July 4, 2025. Per the IRS, the credit is not available for any property placed in service after December 31, 2025 - and the IRS counts the installation completion date, not the contract date.
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 Whitmire roofs
The honest 2026 answer for Whitmire: solar pays back slower without the 30% credit - paybacks that ran 7-10 years often now run 10-14 - but electricity rates keep rising and hardware is the cheapest it has ever been. The deciding factor is South Carolina's export compensation, covered in the net metering section.

Common questions
How much does home solar cost in 2026?
The U.S. marketplace average is about $2.58 per watt installed - roughly $15,500 for a 6 kW system and $31,000 for 12 kW, before any state incentives. Quotes meaningfully above that level deserve a written explanation of what justifies the premium.
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.
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.
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.
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.
