Solar tracker circuit

This circuit is an one axis solar tracker.

Today this circuit used in modern solar street light and solar systems in homes for increasing the efficiency.

I tested it and work well.

Best dc motor for this circuit is cordless drill motor (without removing gearbox)because that is very powerful and can move your heavy solar panel easily.

In following video you can see how it work, however i test it without solar panel.
