I don't think it'd be done as a line tap.
My *guess* at how it would be setup would be a 400A main panel with a pair of 200A breakers. One of those would feed a 200A subpanel which would have a 150A breaker that'd go to a subpanel for the loads, and a 80A for the breaker for the solar.
Or it'd be one 200A breaker to a subpanel for generation and the other 200A breaker to all loads.
My *guess* is that it'd be the first choice - and it'd be 200A for barn (including solar production) and 200A for the house.
But it is just a guess.
