Arduino solar tracker circuit diagram in the circuit two ldr light dependent resistors sensors are used to sense the light.

Sun tracking solar panel using arduino circuit diagram.

The produced electrical energy can be increased if we move the solar panel as the movement of the sun. The circuit design of solar tracker is simple but setting up the system must be done carefully. In this project we are going to show you how to make an arduino based solar tracker using ldr servo motor. We have designed a single axis solar tracking system.

Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of 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. Aim of the project. 1 shows the circuit of the solar tracking system.

In this article we are going to make a sun tracking solar panel using arduino in which we will use two ldrs light dependent resistor to sense the light and a servo motor to automatically rotate the solar panel in the direction of the sun light advantage of this project is that solar panel will always follow the sun light will always face towards the sun to get charge all the time and can. Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun. These provide the signal to motor driver ic2 to move the solar panel in the sun s direction. 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.

A single axis solar tracker improves solar output by around 25 and a dual axis tracker by around 40 according to this article on altestore. Generally solar panels are stationary devices which is fixed at a position. The sensors are connected in series with 10 k ohm resistors. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino.

The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun. The aim of this solar tracker project is to keep the solar photovoltaic panel perpendicular to the sun throughout the year in order to make it more efficient.

It searches for the brightest light source like the sun.
