Please note when using or testing, DON'T keep the motor running over 20 seconds on each motor movement (usually the motor will just run for 3 ~ 6 second every time when the side sensor was shined by the sun, and it will move along with the panel to the correct position and avoid sunshine).
Especially during sunset, make sure the side sensor can avoid sun light until fully sunset
The circuit will be burnt when circuit keep running in high current too long.
(we don't suggest to use limit switch in end of western position)
We guarantee 100% money back, but not just rate us negative. This did not help to solve and improve. If the above was not accepted, please do not buy this.

This solar tracker will drive motor to position you want to track the sun. It can help to get up to 65% more power in your solar system.
It can be used on solar cells, a reflector to heat water, etc.
The controller is mounted on the object to be steered with the sensors positioned along the rotational axis.
Using most any D.C. motor up to a max of 12VDC,4 amps, it can easily cause a solar collector, reflector or array to follow the sun through a single axis.
Motors suitable for this system can move quite large loads as long as proper gearing or lead screws are used.
The controller uses a differential sensing approach and can drive the motor in either direction.
In the morning the east side sensor will be shined and the controller will position to the morning sun.

The solar tracker is operated with 1x12V battery (excluded), details can be check from the instruction in the package.

Input power : DC 12V ( One 12V battery need )
output power : 12V @ 4 amps
