Have you acquired a business that has an existing solar system that is 20 kW or smaller? Unlike electric, gas and outdoor lighting service, the solar service does not automatically transfer to the new account. It must be applied for by the new owner. Once the Transfer of Solar Service application process is completed in our PowerClerk system, the solar generation meter will be reconnected.
You must be the owner in order to apply for solar service. If a renter/tenant starts service at a premise that has solar service, they will not be able to have the solar service reconnected and benefit from the solar generation.
When you start the application process you will be asked to provide your contact information, which should match the Dominion Energy's account holder information. You will need to upload your Property Insurance Policy. Please be sure that the policy contains the following: Insured Name, Insured Address, Start and Expiration Date of the policy, and the Liability coverage of at least $100,000 per occurrence.
Within 3-5 business days of receiving your submitted application, you will receive an email from us via DocuSign. Please read the Interconnection documents and, if you agree, DocuSign will guide you through electronically signing your documents.
Once you have signed your documents, we will reconnect the solar service within 5-10 business days (weather permitting). You will receive an email with your official “Approval to Energize”, which means you can activate your Solar Energy System.
A $50 Transfer fee will be added to your next bill after you receive your approval email.
If you do not know how to turn on your solar system, you will need to reach out to the previous owners or to the solar installer for assistance.
To transfer a Solar System larger than 20 kW, please email SCElectricTransmission@DominionEnergy.com.
