The auto tracking controller circuit of solar power

There are two kinds of auto tracking controllers of solar power: one is that a LDR and Schmidt trigger or a single stable trigger compose a light controlled Schmidt trigger or single stable trigger, which is to control the running/stopping of the motor; the other is that two LDR and two comparators respectively compose two light controlled comparators that control the motor. As the light and its strength change a lot in different seasons and hours, so it's hard for the above controllers to make the solar tracking equipment follow the sun.
