I strongly support @mauried. The KISS principle is essential.
The sun doesn't do 360deg unless you are above the Artic circle.
If the device is to be deployed at a regular property, instead of a motorhome or boat, then it's utterly improbably that the property owner doesn't know the direction of the sun at midday, and can't find out within a day or two.
Tracking the sun was successfully figured out with great precision 5000 years ago.
The more moving parts the more opportunity there is for something to go wrong - especially something that is exposed to the weather 24/7. Would the "helpless" owner be better with something that has extra energy but breaks down and needs to be fixed by a specialist or something with less output that doesn't break down? Will the extra energy comfortably pay for the breakdown service and leave a significant "profit"?
You need to analyze carefully the extra energy you will get from tracked vs stationary panels. This website can help http://re.jrc.ec.europa.eu/pvgis/apps4/pvest.php
I have 3x 80w solar panels on my boat and they lie flat on the roof for two reasons. It would be grossly uneconomic to make a strong enough "machine" that could elevate and rotate them. And, while I could orient them manually (lift them with a piece of wood under one side) I would have to readjust them through the day and I would get less output if (as is likely) I forgot to readjust them. As it is they will have paid for themselves in three years by making a very nice contribution to my electricity needs - except, perhaps, in Winter.
