How to configure a tracker to lock the rotation

[Antonio Augusto Ananias]

I would like to know whether it is possible to use an already existing PVsyst simulation configured with single-axis trackers and simply lock the tracker rotation, keeping the modules fixed at a single tilt angle (for example, by using the stow position).

Specifically, is there a way in PVsyst to block the tracker rotation and manually define a fixed tilt angle for the modules while maintaining the original tracker-based geometry and layout?

Or, alternatively, if the intention is to simulate the system with a fixed tilt, is it necessary to rebuild the entire model using fixed structures with the desired tilt angle instead of trackers?

It is easier to transform fixed tilt structures to trackers in the 3D scene, using the Transform menu. The other way around can be more of a hassle.

The wind stow option is a good option. it necessitates however to import weather data from a file in which you prepare a wind speed time series > some number.

Another option is setting the tracker limit angles to e.g. min X and max X+1° if you are okay to fix the tracker to this 1° range. X and X might work too, though I would double check the output with the X, X+1 to make sure it is consistent.

Curious why you have included the +1 there. You can simulate a tracking system at [X,X] for min and max to lock the tracker for all hours to a single angle. If you need to more than one angle, this can be done with batch simulation easily.

Good to know it works ! Actually I was not sure if [X,X] worked, I seemed to remember that at some point in the past the trick did not work unless there was a difference between min and max.
