The use of a solar.

Circuit diagram of dual axis solar tracking system using arduino.

Dual axis solar trackers uses the motor to move the solar panel in all four directions north south east west. 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. 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. 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. 1 shows the circuit of the solar tracking system. 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.

Circuit diagram simple solar tracker circuit diagram working. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. Solar tracker using arduino. Circuit connections are shown in the circuit diagram tab.

One of them is the single axis solar tracker and the other is dual axis. In this arduino solar panel tracker arduino is powered by the 9v battery and all the other parts are powered by the arduino. The circuit design of solar tracker is simple but setting up the system must be done carefully. 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. Circuit diagram and explanation. We all know that when the intensity of light falling on a ldr increases its resistance decreases.

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. 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.
