Figure 7: Bolt mounted perpendicular to solar panel angle.
The LED’s on the Photo Sensor circuit board can be slightly adjusted to fine tune the accuracy of the solar
tracking. The goal is to eliminate the shadow casted by the bolt in Figure 7. The LED’s can be moved slightly
up or down to accomplish this task. Warning: Do NOT bend the LED’s more than 15 degrees from the factory
set positions!
Figure 8: Bending directions for fine tuning the eight LED’s on the Photo Sensor circuit board.
To adjust the LED’s use the following table:
LED Adjustment Direction Result
D1 and D2 move up
move down track more north
track more south
D3 and D4 move up
move down track more south
track more north
D5 and D6 move up
move down track more east
track more west
D7 and D8 move up
move down track more west
track more east
It is highly recommended that the LED’s are adjusted on a sunny day with no clouds blocking the sun’s light.
Clouds or anything else slightly blocking the sun’s light will negatively affect the accuracy of the LED fine
tuning.
Once you are finished adjusting the LED’s on the Photo Sensor, re-attach the Photo Sensor Dome and
tighten the set screws using the Allen wrench.
