I am designing a solar tracker and using a slew drive to rotate the panels from from east to west every day.

Now, I would like to install a sensor that can be used to determine and calibrate the position of the slew drive, say at the end of each day. I am thinking of using a hall proximity sensor, such as this one: hall sensor.

Would this be a good sensor or are there better solutions for this. Any idea is helpful.

thanks

  • \$\begingroup\$ Just have control that maximizes the panel output power at all times - simplest I saw was 2 small 3V panels in a V and a lens made from a jar of water driving a small motor... \$\endgroup\$ – Solar Mike Mar 14 at 8:38
  • \$\begingroup\$ That is indeed also possible. In this case were are tracking the sun based on the time of day. I have attached a link to a slew drive in the post. \$\endgroup\$ – roadrunner38 Mar 14 at 9:53
