<p> That is correct so long as "A" is the area of the full array (12
times the area of a single module) and so long as "M" is twice the
flow rate that you want to go through each collector.
Mathematically:</p>
<p>M = X * Ntotal / Nseries</p>
<p>where M is the pump flow rate, X is the flow rate per collector,
Ntotal is the total number of collectors (12), and Nseries is the
number of collectors in series per parallel path (6).</p>

<p> I'm not 100% sure that I follow your logic but you can
model that array with a single instance of Type1. If your
single module has an area of 1m2 and wants a flow rate of
400kg/h then the full array of 50 modules (10 in parallel, 5
in series) would have:<o:p></o:p></p>
<p>area = 50 m2<o:p></o:p></p>
<p>number in series = 5<o:p></o:p></p>
<p>flow rate = 4000kg/h (400kg/h x 10 in parallel)<o:p></o:p></p>

<p> This is a common source of confusion. Two points are
important to keep in mind. First, the collector array area
parameter is the area of the entire array, not just the area
of one module in the array. Second, if you add a second
collector you have to be careful about what you do with the
flow rate. If you are adding a second collector in parallel
to the first one you should double the collector array area,
leave the "number in series" parameter set to 1, and double
the liquid flow rate to the array. If you are adding a
second collector in series with the first one, you should
double the collector array area, set the number in series to
2, and leave the liquid flow rate unchanged.<o:p></o:p></p>
