[TRNSYS-users] Solar Panel Type 1b

[David BRADLEY]

Patrick,
  The "collector area" parameter is for the entire array, not for a 
single panel. I believe that we clarified the "more" button information 
with the release of TRNSYS 17 to say: The total area of the solar 
collector array consistent with the supplied efficiency parameters 
(typically gross area and not net area).
Kind regards,
  David
