Understanding Duke Energy's Net Metering Program

North Carolina currently has one of the best net metering policies in the country. Under Duke Energy's program, you receive a full 1-to-1 credit for every excess kilowatt-hour (kWh) your panels send to the grid. These credits are applied to your bill for power you use at night or on cloudy days, drastically reducing what you owe. This robust policy makes solar-only systems highly effective and financially attractive.

Projected Savings

Your Estimated Monthly & Lifetime Savings

This translates to an estimated annual savings of $685, effectively cutting your electricity costs by 70-80%. Over the 25-year lifespan of the solar panels, total savings can exceed $24,000, factoring in likely utility rate increases.

Local Questions Answered

Is adding a battery worth it in Stallings since net metering is so good?
Financially, a solar-only system has a faster payback (around 12 years). However, many homeowners add a battery for energy security. It provides seamless backup power during grid outages caused by storms and ensures you are protected if Duke Energy ever changes its net metering rules in the future.
Do I need approval from Stallings to install solar panels?
Yes, you will need a permit from the town of Stallings or Union County, depending on your exact location, before installation. Your solar installer will handle the entire permitting and inspection process with both the local jurisdiction and Duke Energy.
How much does my home's orientation matter?
A south-facing roof is ideal, but east and west-facing roofs are also highly productive in the Stallings area. Our calculator can give you a more precise production estimate based on your specific roof.
