Hello, I noticed that the SolarAnywhere website states that the use of typical DNI year files may produce more representative results for tracker systems vs using typical GHI year files. I was wondering if PVsyst had any recommendations as to which file should be used for modeling tracking systems. Does PVsyst recommend the use of TDY files over TGY files from SolarAnywhere in some cases? Thanks

Hello, I have a similar question for how PVsyst V8 handles tracking systems on a tilted axis when averaging for topography. The model I am working with has two different averaged orientations (see image below). When assigning these orientations to the system, we notice that the report indicates the following under the PV Array Characteristics for the subarrays: Our question is where is the -90 degree azimuth coming from. Our thought is this could be due to the fact that the orientation is averaging trackers which are tilted to the north and tilted to the south, but we have been unable to confirm this. Is the simulation using a -90 azimuth for the calculations? Any clarity here would be helpful. Thanks

Hello, I am looking to model a system with DC converters in parallel with inverters. Is the above comment to oversize the inverters to account for the DC converters still the recommendation?

Hello, Understanding that it appears that this is something in the works for Version 8, what is the current recommendation regarding modeling sites with significant sloping and/or variations in topography. Do you recommend relaxing the "Tracking: maximum axis tilt spread" and "Max. tilt for the Bifacial 2D model"? Additionally, can you provide some detail on how PVsyst determines the "averaged orientation" and do you have any recommendation for analyzing the uncertainty introduced by modifying the tilt limitations?
