Analyst Note: The "4kW Benchmark"

The analysis below uses a standardized 4kW system to provide a fair baseline comparison across cities. However, the average electric bill in Greenville is $133.1.

Homeowners across Pitt County are feeling the pressure of steadily rising Duke Energy rates. With electricity costing over 12 cents per kilowatt-hour, a typical $133 monthly bill adds up fast, especially during humid Greenville summers. Going solar provides a powerful way to lock in lower energy costs for decades, taking advantage of the abundant North Carolina sunshine.

Duke Energy's Net Metering Program

North Carolina's net metering policy is one of the best in the Southeast. Duke Energy provides a 1-for-1 credit for every excess kilowatt-hour your panels send to the grid. This means you get full retail value for your surplus energy, which rolls over month-to-month and helps zero out your bill. This simple, effective program makes solar a financially sound investment without needing a battery for savings purposes.
