			==Occlusion Based Systems==
			*Use either a Shield, or the panel/dish itself to cover at least 4 sensors (Photoresistors, or small solar cells)
			*When exposed to light one or more of these will change state, thus one can deduce which way the sun is facing
			*Via wiring and/or logic circuits this can directly drive motors for small systems, or send data to a simple controll circuit for motors
			*Very simple, yet very acurate
			*Used to keep solar shields facing twards the sun for some sattalites (Thus not requiring communication based, or calculation based systems)

	Rather than relying on feedback, this method uses an equation (or tables of values) to calculate the sun's path and the appropriate rotation of the mirrors. Such could be implemented through a computer running a program with output to a stepper motor or linear actuator via parallel or serial port. It could also be implemented with a microcontroller ([http://www.arduino.cc/ Arduino board]), which would be a much lower power solution.
