RACKING
This step is optional. The SunTura Solar Tracker should track the sun with an accuracy of +/- 7 degrees or
better with no fine tuning. Mounting the Photo Sensor slightly off angle (human error) with respect to the
solar tracker can lead to a slight tracking inaccuracy. If you wish, the LED’s can be adjusted to provide
optimal tracking accuracy.
(Do NOT attempt to fine tune the LED’s until the Photo Sensor has been
fastened to the solar tracker and is in its final position)
To do this, first mount an object on the solar
tracker that is perpendicular to the solar panels. This will be used to generate a shadow from the sun’s light.
Below is an example.
