3.2.4.1 Mounting the Photo Sensor
Use the included Allen wrench to loosen the two set screws that secure the dome to the Photo Sensor. After
the set screws are removed, pull off the Photo Sensor Dome. Note that it is easier to remove the Photo
Sensor Dome if a flat head screw driver is used to help lift up the Photo sensor Dome. See Figure 5 below.

screw driver.
Next, mount the included screw sets into the three holes on the Photo Sensor. These screws can be used to
mount the Photo Sensor to the solar tracker.

3.3 F INE T UNING THE LED’ S FOR O PTIMAL S OLAR T RACKING
This step is optional. The SunTura Solar Tracker Electronics 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.
