Frequently Asked Questions

For additional program details or questions, contact Duke Energy by calling 866.233.2290, or send an email to NCSolarRebate@duke-energy.com.

  • You can apply for a rebate reservation before installing your system. If your decision to install is dependent upon receiving a rebate, it is recommended that you wait to install your system until after you have received your rebate reservation. If you're accepted into the program, you will receive an email confirmation with your rebate reservation. Once you've received the confirmation, you can move forward with your installation.
  • We will offer 20 MW of capacity for this program each year until 2022. Ten MW will be available in the Duke Energy Carolinas service area and 10 MW will be available in the Duke Energy Progress service area. In each service area, the 10 MW will be split among homes (minimum 5,000 kW AC), businesses and nonprofits (maximum 5,000 kW AC).
  • The incentive shall not exceed 10 kW AC for residential solar systems and 100 kW AC for nonresidential solar installations.
  • Customer shall receive a one-time Solar Rebate payment based on the AC nameplate rating of the customer’s solar PV electric generating system.
  • Residential customers: $6,000 rebate maximum. Customers can get 60 cents per watt of solar energy installed. A larger system may be installed, but this incentive is limited to up to 10 kW.

    Nonresidential customers: $50,000 rebate maximum. Customers can get 50 cents per watt of solar energy installed. A larger system may be installed, but this incentive is limited to up to 100 kW.

    Nonprofit customers: $75,000 rebate maximum. Customers can get 75 cents per watt of solar energy installed. A larger system may be installed, but this incentive is limited to up to 100 kW.

  • Yes. Each year, we offer 2,500 kW per jurisdiction to nonprofit organizations. 50 kW of that 2,500 is set aside for use by the NC GreenPower Solar School Pilot or a similar program.
  • Based on current net metering law, any customer receiving service under a time-of-use demand rate schedule will retain their renewable energy credits (RECs).

    For any customer receiving service under a non-time-of-use demand rate schedule, any renewable energy credits (RECs) shall be retained by the company.
  • The contract period for service under this rider is 10 years. If the solar system is removed, rendered inoperable, the agreement for electric service is terminated or electric service is discontinued under the rate schedule as prescribed in availability section of this rider prior to 120 months, the customer shall be subject to an early termination charge.

    If within 90 days of electric service termination a new customer takes over the site and elects electric service and assumes the customer’s obligations under this rider, including but not limited to continued electric service under an eligible rate schedule and rider NM, the termination charges will be waived.

    An early termination charge shall equal to one minus the number of months since initial participation divided by 120 multiplied by the rebate payment amount.
  • The program resets each year on Jan. 1 through 2022. If in any year a portion of the incentives goes unsubscribed, the company may roll excess incentives over into a subsequent year’s allocation. Any unsubscribed capacity, regardless of any set aside requirement, available on Jan. 1, 2023, shall be available to any customer meeting the rider qualifications.

For a nonresidential customer who obtains a rebate reservation prior to installation, the installation must be completed no later than 365 days from the date of an executed interconnection agreement by the company. 

    For a nonresidential customer with a project under 20kW that does not require an interconnection agreement, the installation must be completed no later than 365 days from the date the rebate reservation was obtained.
  • No, all rebates will be paid to the customer.
