    A Tigo setup would be able to deal with multiple orientations and partial shading. With a Tigo setup, each panel on the system can be different and have a different orientation. The only limitation is not with Tigo but with the main inverter. Your main inverter may require a certain voltage to function properly. That may means having a minimum of 7 to 8 non-shaded panels at all times.
    Good point, though it can be a surprisingly low voltage and still yielding useful power. I have seen my Morningstar TS-600-60 producing with 160V and full current. That's only about five unshaded panels in a string of twelve.
