3 Problem with PVsyst 8.0.15

[Pattarporn]

Hello, I have run PVsyst 8.0.15 for one project, a Solar Rooftop, and encountered the following issues:

1. 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?

2. 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?

3. 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?
