Circuit Diagram Of Dual Axis Solar Tracking System Using Arduino

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.

Circuit diagram of dual axis solar tracking system using arduino.

The circuit design of solar tracker is simple but setting up the system must be done carefully. 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 pwm inputs of two servos are given from digital pins 9 and 10 of arduino. Solar tracker using arduino.

In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino. The use of a solar. 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. 1 shows the circuit of the solar tracking system.

Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. Circuit connections are shown in the circuit diagram tab. One of them is the single axis solar tracker and the other is dual axis. Dual axis solar trackers uses the motor to move the solar panel in all four directions north south east west.

Similarly connect the gnd pin from the arduino to a second lower horizontal row of the breadboard. The heart of the above circuit is two voltage comparators made using lm358 dual op amp. In this system the whole solar panel moves from east to west in a day to point in the direction of the sun. Circuit of solar tracking system.

We have designed a single axis solar tracking system. Circuit diagram and explanation. 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.

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. Circuit diagram simple solar tracker circuit diagram working.
