There seems to be a bug in PV-Syst V6.46 when using 4 orientations and 4 subsystems. I have defined the following orienations under 'Orientation': Orient#1: 2.0° -150° Orient#2: 2.0° 30° Orient#3: 2.0° -60° Orient#4: 2.0° 120° In 'System' I have defined 4 subsystems. Subsystem 1 has Orient#1, Sybsystem 2 has Orient#2, ... All Subsystems have the same inverter model and PV-module. I have also defined a 3D shadow model (in 'Near shadings definition'). In the 3D shadow model I have used the same 4 orientations as defined under 'Orientation'. Furthermore I have made sure that the PV active surface in the 3D model corresponds with the amount of modules defined in 'System'. So far so good. I then run a standard simulation. But when I look in the simulation report, I always see on page 1, that the Tilt/Azimuth for Subarray#4 with Orient#4 is 0° Tilt and 0° Azimuth. Although this was defined as Tilt 2.0° and Azimuth 120°. When I close the report and go back to PV-Syst, I see under 'Orientation' the following tilts and azimuths: Orient#1: 2.0° 30° Orient#2: 2.0° -60° Orient#3: 2.0° 120° Orient#4: 0° 0° It's like all orientations have shifted 1 place up and that Orient#4 has been given tilt 0° and azimuth 0°. No matter how many times I reset all orientations correctly and reperform the simulation, the orientations alwas kept being reset. Is there a way to fix this? Best regards, Mathieu
