Hello, I have run PVsyst 8.0.15 for one project, a Solar Rooftop, and encountered the following issues: Running PVsyst with 3D or Near Shading enabled takes approximately 1 hour and 30 minutes, even though the 3D model does not contain any complex structures. I have therefore set it to run in Fast mode. How can this issue be resolved? In the Detail Loss section, I set the Soiling Loss to 3.5%, and the report correctly shows 3.5%. However, in the Loss Diagram, it displays as 3.25%. How can this discrepancy be corrected? Since I ran the 3D simulation, and the site is expected to have significant shading based on the site survey, I was surprised to find that the Near Shading loss is displayed as a positive value in PVsyst. How can this occur, and is there a way to adjust the settings so that the value appears as negative?

Hello, I have problem with PVSyst 7.4.8. I want to run the project with bifacial module with solar farm dome (2 orientation) but it can not use and have notice “at present, you can only define Bifacial systems with regular arrays of shed-like or horizontal axis trackers. How can I solve this problem? Thank you.

Hello, I have some problem about PVsyst. Last week I installation PVsyst 8 and I already have PVsyst 7.4.2 in the same account and Today I see that the project disappears already. It don’t have any project in PVsyst 7.4.2 but have some project in PVsyst 8.0. How can I solve the problem? I can get all the project back?
