Good morning, I have a problem modeling a tracking 2 axis, frame N-S (axis tilt 0°, axis azimut .45°, frame phi +/- 50°, tilt frame 0/90°) As you can see from the image attached, especially during cold months, early in the mornings, the tracking arrays show an incorrect position (phi angle +50°, tilt about 80°) with respect to the optimal position in which they would optimize their irradiation (phi angle -50°, tilt about 0°). Am I mistaken the setting of any parameter or is it a software's "bug"? Thank you in advance, kind regards. Stefano

Hi everyone, I have simulated a 1 MWp PV plant composed by different rows with PVsyst 5.71, after having introduced horizon profile and near shadings. While it's simple to understand geometrically mutual shadings increasement with higher tilt angles, I can't explain why, increasing the modules tilt angle from 14° to 34°, far shading losses increase from 1,60% to 3,20%. Thank you, best regards. Stefano
