Understanding Duke Energy's Net Metering
Rocky Mount is in an excellent position for solar because of Duke Energy's net metering program. This policy ensures you get full retail credit for every excess kilowatt-hour (kWh) your solar panels send back to the grid. Essentially, the grid acts as a storage bank for your extra power, which you can draw from at night or on cloudy days, maximizing your savings with a solar-only system.
Projected Savings
Expected Monthly & Annual Savings
