Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board.
Circuit diagram of solar tracking system using arduino.
As such it is vital that those in engineering fields understand the technologies associated with this area.
Circuit of solar tracking system.
The heart of the above circuit is two voltage comparators made using lm358 dual op amp.
Arduino solar tracker circuit diagram.
Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.
Solar tracking system circuit fig.
1 shows the circuit of the solar tracking system.
First download the zip file and extract it you will find a circuit diagram of the project.
In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun.
Solar energy is rapidly gaining notoriety as an important means of expanding renewable energy resources.
The circuit diagram shown below.
In this project we are going to show you how to make an arduino based solar tracker using ldr servo motor.
Circuit diagram simple solar tracker circuit diagram working.
Circuit diagram the circuit design of solar tracker is simple but setting.

This solar tracking system starts following the sun right from dawn throughout the day till evening and starts all over again from the dawn next day.
A solar panel is used to harness solar energy.
Solar tracking allows more energy to be produced because the solar array.
Also since a panel which is incident to the sun can gather more amount of solar energy the solar panel is attached to a motor.
Solar tracking system full circuit diagram available.
The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
In the circuit two ldr light dependent resistors sensors are used to sense the light.
We have designed a single axis solar tracking system.
Arduino recommended input voltage is from 7 to 12 volts but you can power it within the range of 6 to 20 volts which is the limit.
Pcb design for arduino solar tracker.
The signal wire of the servo is connected to digital pin 9 of the arduino and gnd gnd vcc 5v of arduino one terminal of the ldr1 and ldr2 is short circuited and connected to the 5v pin of arduino and other terminal of the ldrs is connected to the pin a0 and a1 of the arduino.
Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino.
In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino.
This is useful for zero pcb or breadboard circuit.
We all know that when the intensity of light falling on a ldr increases its resistance decreases.
Our project will include the design and construction of a microcontroller based solar panel tracking system.
