A diagram would help me understand

 

We have upgraded to Premium 7 and the tracking option has disappeared as an option.  is it still a there and hiding?

 

I have been looking at east-west tracking, so north south axis of rotation. with the modules flat (not tilted to the south).  several frame companies are claiming 20% yield improvement. with PVwatts i get the improvement but with PVsol and PVsyst I don't. 

 

Thanks
