Adding New Subpanel - Questions

[The Critic]

Greetings,

My house has a meter/main combo panel with 4 breaker slots (fig 1 and 2). Two slots are occupied by a 100A breaker that runs to an "intermediary" (fig 3), which then supplies a 100A subpanel (fig 4).

The 100a subpanel (fig 4) is fully occupied, so I would like to add a new 100a subpanel. My questions:

1) Would it be possible to relocate the 50A a/c breaker to this new 100a subpanel but keep the 30a PV backfeed in the meter/main combo panel? The electrician seems to think so, but I wasn't aware that you can find a 30/100 breaker of this type?

2) I believe I have 200A service coming into the meter/main combo panel - is this correct?

Thanks in advance!

These are questions for your electrician. He will need to clean up the sloppy wiring in your panel before your inspection, and provide panel schedules, sharpies are not allowed. We are unable to assist any further.
