mathieu.vandenbulcke Posted October 6, 2016 Share Posted October 6, 2016 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 Link to comment Share on other sites More sharing options...
