[TRNSYS-users] Mistakes configuration serie-paralel type 1

[Jeff Thornton]

Alex,

Your e-mail is  a bit confusing.  You state that you have a total area 
of 15 m2, but then go on to describe two arrays that don't have a total 
area of 15 m2.  Please clarify.  You should also check the archives as 
we've discussed the collectors in series thread multiple times.  I've 
also attached a picture for you to study.  Given the same collector 
performance and array flow rate, each of the 4 arrangements shown in the 
diagram will provide IDENTICAL results.  By understanding why that is 
the case, you should be able to quickly resolve your particular 
scenario.

Jeff
