Circuit Diagram Of Dual Axis Solar Tracking System Using Arduino

In this solar tracker project we will design a simplest single axis solar tracker and its concept can be expanded to make a full fledged dual axis solar tracker.

Circuit diagram of dual axis solar tracking system using arduino.

Single axis solar tracking system moves the solar panel from east to west in a day to point in the direction of the sun. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. We all know that when the intensity of light falling on a ldr increases its resistance decreases. Interfacing dual axis solar tracker arduino project using ldr servo motors connect 5volt pin from the arduino to the lower horizontal row of the breadboard.

One of them is the single axis solar tracker and the other is dual axis. Similarly connect the gnd pin from the arduino to a second lower horizontal row of the breadboard. 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. 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.

The pwm inputs of two servos are given from digital pins 9 and 10 of arduino. Circuit diagram and explanation. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. Solar tracking system circuit fig.

We have designed a single axis solar tracking system. The heart of the above circuit is two voltage comparators made using lm358 dual op amp. The use of a solar. 1 shows the circuit of the solar tracking system.

In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino. Circuit diagram simple solar tracker circuit diagram working. Circuit connections are shown in the circuit diagram tab. The circuit design of solar tracker is simple but setting up the system must be done carefully.

Four ldrs and four 100kω resistors are connected in a voltage divider fashion and the output is given to 4 analog input pins of arduino. Solar tracker using arduino.
