If your system is located in DC, here is what we need from you to register your system:
Your interconnection document — your utility's final approval to operate. See Interconnection Documents for what this is and how to get it.
Your system plans — the design drawings from your installer. DC requires these for every registration, so send them even if another state wouldn't need them.
If a company owns your system rather than a person, a DC-issued Certificate of Good Standing for that company.
We confirm whether your system is eligible for DC before registering, so you don't need to work that out yourself.
