Shading Losses due to ground slope

[anastasisp]

Hello everyone,

I am trying to implement a PV site in PVsyst which will be constructed on a terrain with a slope of 10 degrees West. What i am doing is , i change the Baseline slope in the 3D modeling. But i don't know if this is the correct way.

The issue is that when i change the baseline slope it calculates new tilt and aximuth than the one that i have given it in the Orientation section.

Thank you
