Are solar panels worth it for Duke Energy South Carolina customers?
Yes, with a strong South Carolina tax credit of 25% of your solar purchase and installation costs, solar panels for your home make a lot of sense for Duke Energy customers. 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 South Carolina offer net metering credits for exported solar power?
No, Duke Energy South Carolina does not offer full 1 for 1 net metering. This means that when you export surplus power from your solar panels, you will be paid less by the utility than what you are charged to buy the equivalent amount of power from the grid.
If you have excess energy credits after offsetting your usage over the course of a year, Duke will pay you out for those credits at an Excess Energy rate of $0.0432 per kWh. After that, the amount of Excess Energy in your account will be reset to zero.
What incentives, tax credits, and rebates are available to Duke SC customers for installing solar?
The biggest financial incentive for solar homeowners is the 30% federal solar tax credit. The tax credit equals 30% of the solar installation costs and directly reduces your federal income tax liability.
Some states and local governments offer additional solar incentives. These incentives include state tax credits, rebates, or performance-based incentives like Solar Renewable Energy Credits (SRECs). The best part is that these local incentives can be used in addition to the federal tax credit!
Here is every incentive you may be eligible for as a Duke SC customer:

Solar Energy State Tax Credit

Net Metering
(State)
Investor-owned utilities are required to offer full retail rate for excess kWh produced. New net metering rules for Duke customers require that participants accept service on a time-of-use rate plan and are assessed a minimum monthly bill. Customers who applied for net metering before June 1, 2021 will receive net metering under the old rules until May 2029. |
