Dear all I 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. Figure: TRNSYS 17 Figure: TRNSYS 18 Please adviseBest Regards
