Hi, I noticed that with the latest version 6.53 the electrical losses acc. to strings calculated for a single-axis tracker without backtracking are unexpected low! A simulation run with PVsyst version 6.39 calculated around 4-5% higher electrical losses for identical system settings. Could you please clarify where these differences arise from? Many thanks, Stefan

Dear André, thanks for your quick feedback. I am designing quite a few installations with Solar Edge and would appreciate if this functionality could be implemented very soon. In the meantime I was thinking to use the mixed oriantation (mixed #1 and #2) tab to be able to simulate the system but I am not sure what the software is actually doing when using this function. I guess it assume 50% of the defined capaity being orientation 1 and the other 50% being orientation 2? Could please clarify? Thanks, Stefan

Hi, I am facing a problem simulating following configuration with PVsyst: Inverter: Solar Egdge SE16k String 1: 38 Modules (north-west) String 2: 26 modules (south east) + 9 modules (north east) I created 3 subarrays with the 3 different orientations and the relevant fractional input of the inverter but PVsyst does not allow me to simulate because it says "9 modules" is below the minimum string length. How can I define "string 2" with 2 different module orientations?? Regards, Stefan
