Terrain Loss from Tracking Shading Scenes

[shri]

Hello all,

When using near shadings and importing a pvc file of a tracking layout that has topographic/elevation data built in, how does Pvsyst calculate the loss due to terrain? I would assume the elevation data would be incorporated per tracker to account for increased/decreased shading loss (since backtracking isn't calculated for every tracker pair). Are differences in tilt, other aspects also captured in the calculations? 

Thanks!

Shading will be accounted for, and will reflect the different heights and tilts for calculating shading. In terms of tilt, the POA irradiance will be adjusted depending on the average tilt of the shade scene. This is done automatically by the software.

Also, when using PVC files or you have any shade scene where individual tracker rows are being modeled, you will need to use the backtracking management option and select a representative pair.
