I can't speak to questions 1 and 3 but I'm using Type 71 in my model and I'm using the same work around as a colleague of mine: insert a new equation and divide the flow rate into the collector based on your particular collector layout (i.e., parallel/series).
It wouldn't make sense in the real world, but apparently it works in TRNSYS. I will need to finish testing and debugging my model before I will be entirely confident with this approach.

Dear TRNSYS-users,I simulated my solar thermal model with type 71,a data reader Type 9e and plotter; so I would like to insert another type 71 collector, but there is an error which says:"The maximum number of instances (1)allowed for type 71 is already reached"My questions are:1- Why It can use just one model of the same panel Type 71?2- It does exist a way to do series/parallel arrangement of this panel?3- Is there a model of solar collector with two inlet and outlet (flowrate)? (because type 71 has one inlet/outlet)Best regardsGiuseppe
