Operation of the Tracking System:<br />
First control grid was designed, which composed of a stand, servo motor and the<br />
solar panel surface. Two LDR’s were placed at the both ends of the control grid<br />
adjacent to each other. The LDR’s were used to sense the solar light intensity;<br />
important for the solar panel orientation, the output signal was read by the<br />
analogue inputs of the Arduino Microcontroller. The microcontroller was<br />
programmed such that, according to the input signal it controlled the servo motor<br />
by sending a signal via the digital pins. I wished to use the Mono-Crystalline solar<br />
module which is made from cells cut from single silicon crystals but replaced that<br />
with an adjustable DC power supply from the LAB 4 – K.U.C.T. The energy<br />
conversion rate efficiency for a mono – crystalline solar panel is 16% (Ideal Case).<br />
