Hello,
Please have a look on my previous work in solar PV systems design and modeling. I have very good experience in shadow study and effects on solar PV systems.

I can build a 3D modeling for your solar PV system using Sketchup with shadow analysis and study. My offer include firstly a Helioscope study for your farm, and then a full 3D model with all details of solar PV panels, mounting structure, inverters ... etc. I will provide an animation with renderings that shows the shadow effect on the panels during day time and with respect to the tracker system.
I need basically the exact location for your farm, the mounting structure, PV panels types, and if applicable some photos to show the effect of the trees and other obstacles.
It would give me great pleasure to hear back from you to have more discussion.
Warmest Regards
Husam
