A Strong Simple Sun Tracker

Step 4 A possible setup

I don't have the equitorial mount ready yet, but the idea is that the control moves the right ascension axis when the Sun Blocker darkens the sensor. The motor drives the array into the direct sun, the sensor shuts off the drive until the sun moves again to shadow the sensor.

And if a dark cloud passes?  Perhaps a second, unblocked sensor to enable the drive only during unshaded conditions.
