Adding solar panels and switching rate plans can lower your Duke Energy North Carolina electric bill

Updated: October 22, 2020

There are three ways you can reduce your Duke NC bill: changing your habits, switching your rate plan, and adding solar panels.

You've probably heard a lot about reducing energy consumption by doing things like switching to LED lightbulbs and adding insulation to your walls, but these fixes are relatively easy compared to the far more impactful step of making changes to your lifestyle.

The second thing you can do is switch your rate plan. Duke NC doesn't offer time-of-use billing that can help you save money by shifting your usage of energy-intensive appliances to off-peak hours, but there may be other options for you .

Finally, you can reduce or even eliminate your electricity bill by installing solar panels on your home.

Are solar panels worth it for Duke Energy North Carolina customers?

Probably. With the 26% Federal solar tax credit, and available North Carolina solar property tax exemption, home solar panels are an investment worthy of your careful consideration as a Duke Energy customer. Duke’s excess solar generation rate rider also allows you to get full credit on your power bill for the excess solar electricity your panels produce which you can’t use onsite. Your credits accrue at the same rate you pay for electricity, and roll over to the next month’s bill.

Does Duke Energy North Carolina offer full 1 for 1 net metering credits for exported solar power

Yes, Duke Energy North Carolina offers 1 for 1 net metering. This means you are paid the same rate for excess solar energy that you export to the utility grid during the middle of the day as what you pay for power purchased from the grid.

In the case of Duke Energy North Carolina, this is approximately $0.11 per kWh.

What incentives, tax credits and rebates are available to Duke NC customers for installing solar?

The major financial incentive currently available until the end of 2020 is the 26% federal solar tax credit. The way this works is that the full cost of the system needs to be paid to the installer, and this tax credit can then be claimed back as cash when you next do your taxes.

Many states, local governments and utilities also offer incentives for homeowners who go solar. This help can take the form of state tax credits, rebates, tax breaks, SRECs or even performance-based incentives. The best part is that all of these incentives apply in addition to the federal credit.

Here is every incentive you may be eligible for as a Duke NC customer:

Duke Energy Solar Rebate Program (Utility)

This incentive program opens applications early each January for installations completed during the previous year. It usually sees about 3,000 applications for the ~1,600 available rebates, meaning some folks who apply won't get the rebate. Installers typically have many employees submitting rebates the moment the online application portal opens. Applications that don't qualify immediately get placed on a waitlist, and may receive the rebate if space opens up. The program runs through 2022.
