South Carolina Net Metering Laws & Utility Buyback

SBI Editorial DeskUpdated Q1 · 20262 sections

South Carolina's net metering landscape has evolved significantly. While early adopters enjoyed simple 1:1 retail net metering, modern solar policies from Dominion Energy, Duke Energy, and Santee Cooper have shifted to encourage Time-of-Use (TOU) rates and off-peak energy consumption.

01

The Shift to Time-of-Use (TOU) Net Metering

Under the updated billing structures (such as Duke Energy's Solar Choice), the value of the excess solar power you send to the grid depends entirely on when you send it. If you export power during low-demand off-peak hours, you are credited at a lower rate. If you consume power from the grid during peak evening hours, you are charged a premium.

02

The Advisory Advantage

Because of these shifting utility policies, standard solar-only systems are less profitable than they used to be. At SunBeam Innovations, we engineer hybrid systems (Solar + Battery). By storing your daytime overproduction in a battery, you can power your home during the utility company's expensive evening peak hours, completely bypassing their punitive Time-of-Use rates and maximizing your savings.
