Daksha Bopanna Posted March 16, 2023 Share Posted March 16, 2023 Hi! How do I fix this error? It shows up after I create my 3D construction scene and the click the Automatic Tilt for trackers option. It has worked in the past for every project but I am now getting this error of one. Link to comment Share on other sites More sharing options...
Michele Oliosi Posted March 20, 2023 Share Posted March 20, 2023 Please read https://www.pvsyst.com/help/bifacial-conditions.htm Your average tilt is likely too high for an accurate backside irradiance evaluation. You can change an advanced parameter (Main window > Settings > Edit advanced parmeters) to proceed anyway. Link to comment Share on other sites More sharing options...

I followed the instruction and increased the threshold (Pitch RMS limit for bifacial 2D models )although I am still struggling with bifacial modeling. could you please advise if I need to amend something else?

Michele Oliosi Posted November 16, 2023 Share Posted November 16, 2023 You should actually change the following other parameter : "Max. tilt axis for the bifacial 2D model" This seems to be the reason for your problem, rather than the pitch Link to comment Share on other sites More sharing options...
