To register your Pennsylvania system for SRECs, we'll need a few things from you:
Your interconnection document — your utility's approval to operate. See Interconnection Documents for what this is and how to get it.
Clear photos of your installed panels.
Access to your system's production data — a recent meter reading from your monitoring portal (e.g. Enphase).
If your system has battery backup, we also need the electrical schematic from your system plans.
Why completing your sign-up sooner earns you more:
Every month you wait costs you that month's certificates. A Pennsylvania system can only sell SRECs from the month its application is submitted, and we submit at the end of each month — so documents that reach us during March earn you March onward, while documents that arrive in April do not.
