You don't say how much electronics and other stuff will be acceptable
in your system; but I believe the practice in some solar systems is
not to attempt to "track the sun" with a feedback system, but rather
to put some simple data about the sun's position versus time into a
computer memory and just "point at the sun", open loop.
