Sun Tracking Solar Panel Using Arduino Circuit Diagram

We have designed a single axis solar tracking system.

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. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. Generally solar panels are stationary devices which is fixed at a position. 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.

These provide the signal to motor driver ic2 to move the solar panel in the sun s direction. It consists of only this components ldr module l293d motor driver module dc motor 30 rpm solar panel. The sensors are connected in series with 10 k ohm resistors. Arduino solar tracker circuit diagram in the circuit two ldr light dependent resistors sensors are used to sense the light.

It searches for the brightest light source like the sun. The dual axis solar photovoltaic panel takes astronomical data as reference and the tracking system has the capability to always point the solar array toward the sun and can be installed in various regions with minor. The circuit design of solar tracker is simple but setting up the system must be done carefully. The pwm inputs of two servos are given from digital pins 9 and 10 of arduino.

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. Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun. 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. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.

When the stick on top is righted to the sun or the brightest point the four ldrs get the same amount of light on them. 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. In this project we are going to show you how to make an arduino based solar tracker using ldr servo motor. 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.

The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
