If you want to obtain what you "know à priori", it is not the good way. Sometimes the real calculation gives defferent values than what you are waiting for.

Now the optimization of the plane orientation for your site may be obtained in detail in "Tools > Transposition factor" (here, please press F1 for Help).

However this optimization is different when you have a sheds (rows) arrangement, due to mutual shadings. For deeply understanding this, please use "Project design > Grid connected > orientation", and choose "Unlimited sheds". Open "Show optimization", and press F1 for explanations.
