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

Dear allI found a problem when plotting out the global solar radiation using type 15-2.Type 15-2 misreads global solar radiation when using TRNSYS 18.While TRNSYS 17 reads the global radiation correct.I used "US-TMY2\US-WI-Madison-14837.tm2" for both cases.
