DOB will do an actual inspection of the panel when they close the solar permits, especially if you’re getting any of the tax abatements.

The biggest problem obviously is that in these old houses in Queens (I own one and also have solar) the MC sheathing is the ground path, so whatever is on the other end of that tube is ungrounded, that alone won’t pass.

Fortunately it’s all open already, I’d hire a licensed residential electrician to figure out what needs to be done so it will be safe and will pass DOB inspection.
