Marking the option "Enable output file" in the Advanced simulation box. It is possible to customise the output values in the same box, in the Preliminary definitions section.

Dear all, I don't understand how the time shift works. (From PVsyst help MeteoNote9) If the meteo data file provides the hourly Global horizontal irradiation, sun's height and azimuth at the exact beginning of the hour, are all these values interpolated to the middle of the interval in order to use them for the simulation? Wouldn't it add an error to the solar geometry calculation, given that the solar movement isn't linear? Katherine

Hello all, How can I obtain a data file with the hourly irradiation values? Best regards, Katherine
