I am a mechanical engineer with intrest in solar generation in the northern latatude 60deg and further where low light intensity and shade. I'm instrested in micro inverters and there special qualities.

Welcome.

 

There is loads about PV on here, just do Google Site Searching as the built in forum search is hopeless.

 

At 60° N it is more about hours than intensity.

As above that far north you need a good clear view south preferably without any hills in the way and a steep panel angle.  If maximum winter yield is your aim almost vertical will work well.  You won't be short of sun hours in the summer.
