Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.
Circuit diagram of solar tracking system using arduino.
A solar panel is used to harness solar energy.
Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board.
Circuit diagram simple solar tracker circuit diagram working.
Arduino solar tracker circuit diagram.
Circuit diagram and explanation.
Circuit of solar tracking system.
The solar panel tracker is designed to follow the sun movement so that maximum light intensity hits on the solar panel thus increasing the power efficiency.
Solar tracking system full circuit diagram available.
Pcb design for arduino solar tracker.
Solar tracking allows more energy to be produced because the solar array.
We have designed a single axis solar tracking system.
Our project will include the design and construction of a microcontroller based solar panel tracking system.
First download the zip file and extract it you will find a circuit diagram of the project.
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.
In the circuit two ldr light dependent resistors sensors are used to sense the light.

The circuit diagram shown below.
The heart of the above circuit is two voltage comparators made using lm358 dual op amp.
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.
In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino.
Solar energy is rapidly gaining notoriety as an important means of expanding renewable energy resources.
The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
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.
In this project we are going to show you how to make an arduino based solar tracker using ldr servo motor.
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.
1 shows the circuit of the solar tracking system.
Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino.
Circuit diagram the circuit design of solar tracker is simple but setting.
As such it is vital that those in engineering fields understand the technologies associated with this area.
We all know that when the intensity of light falling on a ldr increases its resistance decreases.
This is useful for zero pcb or breadboard circuit.
