Post subject:  optimized tilt angle Changes

In PV Syst, If I do Simulation by considering Unlimited sheds & if I do same simulation in Fixed tilted sheds, optimized tilt angle for same location gets change even if all the loses & assumptions are same for both location. Why this happen?

By which amount ?

The shading calculation principles are very different between the 3D and the Unlimited sheds models.
However if you correctly define the 3D scene (i.e. by observing the hypothesis of the "unlimited sheds", i.e. very long sheds or rows), both simulations usually give close values.
Now the optimum tilt angles have a very broad maximum: large interval in tilt may lead to very little yield differences. So that the maximum tilt may be significantly different even with little simulation differences.
