Hi, I am attempting to model a modified single axis tracker in PVsyst by constructing a shading scene in "Near Shadings". I was hoping to simulate a whole (1) MWAC inverter block worth of trackers, but after building the scene and trying to run the simulation PVsyst runs very slowly and eventually ends the program. Therefore, I decided to scale up by tracker rows and E-W center to center row spacing by a factor of 10 in order to run the simulation. That way, the area of shading will be very close to the area of the system and I can produce a shading table. So for instance, if a "real-life" typical row is 2m in width and c-c row spacing is 6.1 m, I scaled them up by a factor of (10) to 20m and 61m respectively in order to successfully run the simulation. Is this the correct approach for using "Near Shadings"? Also, if I am implementing a N-S tilt in my simulation, what does PVsyst assume for shading on the modules in the N-S direction? If the spacing (pitch) is not great enough and there is shading on the modules, how does this affect each individual module's production? Thank you for your help. Tim
