State rules that apply
- What the rule says: “the commission shall establish a "solar choice metering tariff" for customer-generators to go into effect for applications received after May 31, 2021.”[1]
What it means for sizing and batteries
When exports earn much less than retail, each kWh you use at home as it is produced is worth more than one you export. Size to your daytime and evening use, shift loads (laundry, dishwasher, EV charging) to sunny hours or the plan's off-peak window, and price a battery against the gap between the retail and export rates.
The calculator uses the statewide rule until we add utility rates. See what solar costs in South Carolina.
FAQ
Frequently asked questions
Does South Carolina have net metering?
Act 62 (Energy Freedom Act, 2019) replaced traditional net metering for the state's large utilities with PSC-approved 'Solar Choice Metering' tariffs for applications received after May 31, 2021; the tariff must compensate customer-generators for the benefits their generation provides, not necessarily at full retail. Customers who applied earlier keep prior net metering terms until May 31, 2029; utilities with fewer than 100,000 customer accounts are exempt.
