Hello, I designed solar rooftop in several orientations in Sketch up 2019 then imported to PVsyst . PVsyst generates negative tilt angle on PV panels for this reason I can't go on next steps ,what should I do?? Please help ,Thank you in advance. https://scontent.fbkk5-4.fna.fbcdn.net/v/t1.0-9/59655164_2229937417322102_5587581787275526144_o.jpg?_nc_cat=103&_nc_ht=scontent.fbkk5-4.fna&oh=3fc73054b8860d719c5207e9f0a74b4e&oe=5D6721CA https://scontent.fbkk5-5.fna.fbcdn.net/v/t1.0-9/58745233_2229939940655183_369212740432035840_n.jpg?_nc_cat=100&_nc_ht=scontent.fbkk5-5.fna&oh=01485f793d55bea2d7af058c563e068b&oe=5D2E91FC https://scontent.fbkk5-1.fna.fbcdn.net/v/t1.0-9/59400424_2229941647321679_903479141314068480_n.jpg?_nc_cat=109&_nc_ht=scontent.fbkk5-1.fna&oh=49338fd9273cdce6271b132890a8ddc1&oe=5D60F5F1

Hi everyone, I am working for shading loss simulation for PV plant. So, my plant layout is far from mountain around 270 m. , details as below picture https://drive.google.com/file/d/1gbq0jGIvK_elccKFOKBPeRJBeAhTq-3E/view?usp=sharing I would like to know , what option is suitable to calculate shading for this case , Far shading for Near shading ? And if it need to calculate near shading loss option , how can i create the mountain shape as shading object in 3D construction in PVsyst? Thank you in advance!
