How net metering works

When panels produce more than you use, surplus energy flows to the grid. Your utility credits your account — at retail, avoided-cost, or buyback rates depending on policy.

Solar installation costs in South Carolina reflect local labor rates, permit fees, and utility interconnection rules. A typical 6 kW system runs $11,550–$20,440 before the 30% federal tax credit, with net cost around $8,080–$14,310.

  • Daytime surplus → bill credits
  • Evening usage → draw from credits
  • Annual true-up may settle remaining balance
