Understanding Duke Energy's Net Metering Program

North Carolina currently has a favorable net metering policy. When your solar panels produce more electricity than you're using, the excess power is sent to the grid. Duke Energy credits your account at the full retail rate for every kilowatt-hour you export. This ensures you get maximum value from your system, making the 'solar only' option highly effective for cost savings with a payback period of around 11.5 years.

Projected Savings

Real Monthly Savings Against Duke Energy

With an average electricity rate of $0.121/kWh in the Lumberton area, a 4kW solar panel system can generate roughly 5,800 kWh per year. This production is estimated to save you $702 annually, or nearly $59 per month. Over the 25-year lifespan of your solar panels, that amounts to over $17,500 in savings, shielding you from Duke Energy's future rate hikes.

Local Questions Answered

Are solar panels durable enough for hurricane season in Lumberton?
Absolutely. Modern solar panels are built to withstand severe weather, typically rated for winds of 140mph or higher. A properly installed system is designed to handle North Carolina's coastal weather conditions.
Is a battery necessary with Duke Energy's net metering?
For savings, no. Duke's 1-to-1 net metering credit makes solar-only systems very effective financially. However, if your primary goal is to have backup power during outages caused by storms, then a battery is essential. It's the only way to keep your lights on when the grid goes down.
How does the federal tax credit work?
The 30% credit is not a cash rebate, but a dollar-for-dollar reduction of your federal tax liability. For a system costing $11,500, the credit would be $3,450. You must have sufficient tax liability to claim the full amount. Consult a tax professional for advice specific to your situation.
