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

Based on Duke Energy's average electricity rate of $0.123/kWh, a 4 kW solar system in Rocky Mount can significantly reduce your monthly expenses. Expect to save around $710 per year on your electricity bills. Over the 25-year lifespan of the panels, that adds up to over $17,750 in total savings, protecting you from future rate hikes.

Local Questions Answered

Are solar panels durable enough for North Carolina's hurricane season?
Yes. Modern solar panels are built to withstand severe weather, with most models rated for winds of 140 mph or higher. Professional installation ensures they are securely mounted to your roof, providing a reliable energy source even in harsh conditions.
How long does it take for solar panels to pay for themselves in Rocky Mount?
With a net cost around $8,050 and annual savings of $710, the payback period for a solar-only system is about 11 to 12 years. A system with a battery takes longer to pay back (over 20 years) but offers invaluable energy independence during grid outages.
