Circuit Diagram Of Dual Axis Solar Tracking System Using Arduino

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.

Circuit diagram of dual axis solar tracking system using arduino.

The use of a solar. 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 and explanation. One of them is the single axis solar tracker and the other is dual axis.

The heart of the above circuit is two voltage comparators made using lm358 dual op amp. Circuit diagram simple solar tracker circuit diagram working. Solar tracking system circuit fig. 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. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. 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. Circuit connections are shown in the circuit diagram tab. 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. Similarly connect the gnd pin from the arduino to a second lower horizontal row of the breadboard.

Dual axis solar trackers uses the motor to move the solar panel in all four directions north south east west. We all know that when the intensity of light falling on a ldr increases its resistance decreases. We have designed a single axis solar tracking system. Solar tracker 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. 1 shows the circuit of the solar tracking system.
