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?
