Stick with sensing the sun's position, I have a link somewhere to a guy who has built loads of sun-trackers for this application.
Where? I tried searching with no success.

So if I wanted to do 2 axes tracking, what is best strategy? do I do one axis tracking first and stop at maximum signal level then do the other axis and panel position should be center on the sun?
2. is it better to do kartesian or polar tracking in this case?
3. what should the period of retracking be?
