Duke Energy SC has a reduced rate net metering policy. While the buyback rate of 10.36¢/kWh is lower than the 14.8¢/kWh retail rate, solar remains highly economical. The key is to size your system to match your daytime consumption as closely as possible, maximizing direct savings at the retail rate. Any excess generation still earns you credits, just at the reduced buyback rate.
