different modules tilt angels

[Werah]

Hallo!

I am simulating a powerplant in west-east system. This is what I do:

- slope of the surface (0 degree = no slope or -7 degree = slight in teh south direction),

- azimut (0 degree = south direction or -4 = east direction) and

- tilt of modules (from 0 -20 degree) , I change it in "shadow scene" (nahverschattung in german), and than the orientation ist automatically adjustment,

I always get the best results with the modules tilt 0 = Degree. I tried different combinations of these parameteres, and always, when the modules are parallel to the ground I get the best annual yield.

Is there anything wrong in the parameters I am giving?

Hi, this seems normal, if you are using the same number of modules each time.
The advantage of East-West (tilted) systems is that they compensate the worse orientation by allowing you to fit more modules per ground area. Let us know if it checks out !
