 ==== Sunlight Tracker Design ====
 Sunlight trackers increases the amount of energy harvested from the solar panels by maximising sunlight collection. Using azimuth sunlight tracker can significantly increase the energy production by 65% [13].
-The solar cells sets are placed on two sides divided by a board in the middle. Each side of the solar cells sets generate voltage and current. A 12V DC motor with an operating voltage range from 4.5V to 18V and 70 mA no load current will be used. Each solar cell has a rated voltage of 4.3V and hence a set of solar cells has a rated voltage of 12.9V. The current generated by the left-side may be different to the current generated by the right-side due to the Sun location. DC motor rotation direction depends on the polarity of current. Therefore, if the left-side current(I1) is larger than the right-side(I2), the current would rotate in clockwise direction. Otherwise, it would rotate in anti-clockwise direction. If the current difference is slight, the motor would stop working. It would happen only when the solar tracker is facing to the Sun during daytime.

 Sunlight trackers increases the amount of energy harvested from the solar panels by maximising sunlight collection. Using azimuth sunlight tracker can significantly increase the energy production by 65% [13]. The solar panels are placed on two sides.
 The tracker uses two different current sources two groups of referencing solar cells. With the difference between two currents is larger than 0.2 A, the motor starts rotating. The larger the current difference is, the faster the motor runs. And the motor would stop at the position where there is not enough current difference and it means both groups of referencing cells generate the same amount of current. At this point, the solar panel, which is connected to the motor, would be facing the sun.
