[TRNSYS-users] problem with Type 15-2

[David BRADLEY]

Nidal,

  Thanks for bringing this to my attention. The output that is labeled 
"global horizontal radiation (not interpolated)" is actually the "sky 
diffuse horizontal radiation (not interpolated)" It appears that all of 
the calculated quantities of solar radiation on the horizontal and on 
the tilt are correct in both v17 and v18. Is there any chance that you 
could send me the v18 project that you used to generate your plot so 
that I can check to make sure that I am looking at the same thing that 
you are? You can just send the project directly; no need to send it to 
the whole user group.

kind regards,

  David
