<div dir="ltr">Hi Giuseppe,<div><br></div><div>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). </div>
<div><br></div><div>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.</div><div>

1- Why It can use just one model of the same panel Type 71?</pre><pre style="white-space:pre-wrap;color:rgb(0,0,0)">2- It does exist a way to do series/parallel arrangement of this panel?</pre><pre style="white-space:pre-wrap;color:rgb(0,0,0)">
