About solar in South Carolina

South Carolina solar is quietly substantial — about 2,700 megawatts installed — and the pipeline is anything but quiet: 200 megawatts of new cooperative solar farms switched on near Georgetown at the end of 2025, a 360-megawatt portfolio now under construction ranks among the largest solar financings in state history, and Duke Energy is procuring thousands of megawatts more across the Carolinas this decade.
The state's own money is the headline for homeowners. South Carolina's solar tax credit returns 25% of your system's cost on your state income taxes — claimed at up to $3,500 a year and no more than half your tax bill, with any unused credit carrying forward for up to 10 years. Export rules changed in 2022: new Duke Energy and Dominion Energy customers go on the Solar Choice tariffs, a time-of-use arrangement where your production nets against your usage within each pricing period every month and month-end leftovers are credited at a few cents per kilowatt-hour. (Homeowners who applied for classic net metering in 2019–2021 keep those terms until May 2029.)
Because exports earn little under Solar Choice, right-sizing — and shifting usage into sunny hours — matters more in South Carolina than in most states, and battery storage earns its keep the same way.
