G'Day Bruce!
New to the forum .. Here is a link on building a cheap solar tracker ... I think it's really cool .. Check it out ..
Cheap Solar Tracker
I would add a MOP (motor operated potentiometer) at the end of the servo to supply voltage to a small dc motor with an "all threaded rod" to the array .. As the solar tractor detects movement the servo will operate the dc motor to move your array .. It would take a little tweaking but once finished I think you'll have a really cool automatic tracker that doesn't cost a bunch ..
Here is another site to checkout ... Gives parts list for single axis tracking with a dark sensor that allows the array to swing back to the east after dark.
