In this tutorial we will discuss steps to be taken in order to import your layout to PVsyst for the yield estimations.


PVsyst 7 now supports a new unique PVcase format - .PVC. Using this format the importation is way easier and you don't need to select additional information like the axis plane or turning angle range - it will be automatically recognized.

After pressing the Export to PVsyst and selecting the .PVC format and layout will be exported. This exported file will include 3D trees and terrain if they were generated by PVcase.


1. Open PVsyst 7 and select the Near shadings tab.

2. Click on Construction / Perspective.

3. Press File → Import → Import a 3D scene (3DS, DAE, PVC) , and select your exported .PVC file.

4. In Import results window select the input size - depending on your drawing this can be either in metric or imperial units.

5. Click OK.

🛈 PVsyst will automatically identify axis plane and turning angle range specification from PVcase while using the .PVC format.

Backtracking for 2D tables

To enable bactracking for imported tracker tables you need to create a pair of PVsyst trackers and enable the backtracking. After doing this the same backtracking strategy will be applied to the entire scene.

Here's a step by step tutorial on how to do this (a bigger version of the GIF image below can be found here)

  1. After importing your tracker project delete one of the tracker tables.

  2. Double-click on the table next to the deleted one and alter the settings so that they match with the rest of the project.

  3. Go to Tracking parameters and enable Backtracking for the selected tables.

  4. After you run your shading factor table it should say With Backtracking if done properly.

In this way PV syst will apply this backtracking setting to the rest of the power plant.

Due to technical limitations PVsyst is not able to calculate backtracking for tables on terrain.
