I just noticed in a simulation of dual-axis trackers that when I turned on near shading, the far shadings/horizon loss changed. I'm using Version 6.34. With near shadings turned off, the far shadings/horizon loss was 3.7%, and with near shadings set to linear the far shadings/horizon loss was 4.4%. It seems to me that the near shadings selection should not affect the far shadings/horizon loss. Might there be a bug that is causing this behavior?

Thanks for the suggestion to define dummy trackers. I just tried it, and it works for linear shading but not for shading by modules. When I tried with shading by modules first it crashed, then I restarted and ran the simulation but the results show no electrical loss due to shading. Then when I tried to calculate the shadings for the table in the "module layout" dialog a message popped up that said "please define the string attributions for all Tables". It seems that all tables must have PV modules on them, even if the area is very small. Is it possible to change the software to allow tables without PV modules? Is there another way to create a dummy tracker that works with shading by modules?

When simulating a field of dual-axis trackers with a string inverter attached to each tracker, I want to know the energy production of each tracker. This does not appear to me to be possible with the current version (6.3.2) of PVsyst. For non tracking arrays it is possible to build a shading scene with non active (no PV modules) elements replacing the PV elements that are not of interest. But this method does not work for trackers since there is no tracking shade obstacle available without PV modules. I would be able to do the simulations I want if one of the following two features were implemented: 1) Option to build a tracking object in the shading scene that has no PV modules attached to it 2) Ability to view energy production for every inverter in the system Does anyone have a suggestion on how I can build a simulation that shows the annual energy production of a subset of (1 or more, but not all) trackers in a field, shaded by other trackers with the current version of PVsyst? Thanks.
