Well, there are two logical approaches:
1. Assume that there had to be some sort of protection of the bus at 100% of rating before the solar was added and since the service current is not effectively limited, the sum of the load (branch and feeder) breakers (six handles???) in the panel would have to be less than or equal to the bus rating, and adding PV to the panel would not change that in the least.
2. Just assume that the POCO input is magically limited to the service rating and use that in the 120% rule.

Neither one is hallowed by Code, but each has a certain logic to it. :angel:

Actually in those panels, it would be like a line side tap. So technically you would be almost unlimited.

Agreed. This would be a "supply side connection", which is only limited by the maximum breaker allowed in the panel or the service conductors.
