control circuit for solar panel trackier

[redgi]

Good day all

I have very basic electronic knowledge and can build basic circuits. I am building a tracking device that will turn my solar panel from east to west during 8 hours.

The device will be powered by a 12v dc motor that will turn a threaded rod to move the panel through about 90 degrees.

the motor will be controlled by a 12 relay.

I need a circuit diagram that will power the relay to run the motor for 2 seconds at a time, but I would like to be able to adjust the time between runs from approx 30 sec to 5miniutes. also if possible, the motor must reverse after 8 hours until stopped by a limit switch.

Any help would be appreciated

Thank you

Redgi

A typical arrangement would use sets of photoresistors and comparators. Add in a decent dose of 555s. When it gets dark, the motor is driven to the "morning" position where a homing switch cuts off the homing signal. There are plenty of solar tracker circuits.
