Are solar panels worth it for Dominion 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 Dominion Energy South Carolina customers. Dominion'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 Dominion Energy South Carolina offer net metering credits for exported solar power?

Yes, Dominion Energy South Carolina offers net metering credits.

Under the Dominion Energy South Carolina net metering program, solar panels will first send energy to your home. Any excess solar energy is sent to the grid and purchased in the form of a bill credit. The credit value is determined by the Tri-Party Net Metering Power Purchase Agreement. KUA customers are billed for all of the electric energy delivered to them by the company.

If you have excess energy credits after offsetting your usage over the course of a year, Dominion will pay you out for those credits at its "avoided cost" rate (based on the wholesale price of electrcity over the year). After that, the amount of excess energy in your account will be reset to zero and you can begin earning further credits for the next 12-month period.

What incentives, tax credits, and rebates are available to Dominion Energy 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 Dominion Energy customer:

Table 1: Incentives
Upfront Incentives Value*
Residential Clean Energy Tax Credit (Federal) -$5,735
Solar Energy State Tax Credit (State)

25% of costs up to $3,500 or half of state tax liability, per year. Unused credits carry forward for a maximum of 10 years; thus the $35,000 cap.

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.

TOTAL -$12,108

*Based on 10.20 kW system, average installation cost $25,490
