Brief update: I have tried using measured array temperatures with 2 more versions, 6.39 and 6.43. 6.43 did not allow for array temperature consideration. However, array temperature consideration does work with 6.39. Thus it seems, that for my current purposes i have to go with the older and slower PVsyst version.

Hi Andre Thanks for your immediate reply. As far as i can tell i have imported the array temperatures effectively. Jumping to "Characteristics of meteo hourly files - Tables and Graphs" after the ASCII-Import i can actually display the imported array temperatures along with other imported data (namely: global tilted plane values and ambient temperatures). The fact that i can actually display these array temperatures from the generated meteo file indicates an "effective" array temperature import, doesn't it? Nonetheless when assigning the imported meteo file to my project site the option to use measured array temperatures (in the panel: detailed losses/ thermal parameters) is not being displayed. I have repeated all necessary steps several times but still can't make it work. Any idea how to solve this? I am using version 6.4.2 btw. Thanks and regards Christian

Dear Andre Dear Amir I have the same problem as described above. I cannot find the option to use measured array temperature values instead of calculated ones. According to your previous answers i should find it in the thermal parameters panel (detailed losses). However i don't see any option like that. Could you please specify where to find it? Thanks and regards Christian
