Please read the following before buying:
Please see below video showing how the sensor unit work and installed:
Please note when the use of or testing, DON’T keep the motor running over 20 seconds on each motor movement (frequently the motor will just run for 3 ~ 6 second every time when the side sensor was shined by the sun, and it is going to move in conjunction with the panel to the correct position and avoid sunshine).
Especially all the way through 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 toughen. If the above was not accepted, please do not buy this.
This solar tracker will drive motor to position you need to track the sun. It can help to rise 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 relatively large loads so 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.
