Abstract:
This project involves a design of sun tracker for PV system.
The circuit of the sun tracker is designed in such a way that it follows the
track of the sun as it travel in the sky. The LDR are connected to
non
-
inverter input of the operational amplifier whose reference voltage resistor
R1 and R2 is 10Ω each. At the output of the operational amplifier are NPN
and PNP transistor. These transistors are used to drive the DC motor in
forward and backward directions which corresponds to the direction of the
sun in the sky. The motor is switch through a relay.
