Arduino solar tracker using dc motor.

In this project an arduino nano is used which works as a controlling unit. In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. Circuit diagram the circuit design of solar tracker is simple but setting. Dc motor and motor driver.

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. We ll do our best to answer your questions. Finally we have completed interfacing dual axis solar tracker arduino project using ldr servo motors. Two ldr s light dependent resistor are also connected to analog pins of the arduino.

Copy this code and upload it to your arduino board. And a micro servo motor sg90 to control the solar tracker according to the horizontal axis which is the up down servomotor. Solar tracker using arduino. Drop a comment below if you have any doubts or queries.

We hope you found this project useful. Arduino solar tracker working. Below is the program that will interface servo motor ldr with arduino for solar tracking. For designing arduino based solar tracker using ldr servo motor you need to program atmega 328 arduino microcontroller.

This solar tracker control system is designed to take light measurements from the east and west left and right side of the solar panel and determine which way to move the panel to point it directly at. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. The advantage of the servomotor is that we can control its stop run the direction of rotation and speed using a single low current wire connected directly to an output of the microcontroller without needing any drivers. Photovoltaic powers the solar tracker no external source needed.

A dummy solar plate is attached in parallel to the axis of servo motor and both the sensors are kept on the dummy solar plate as shown in the figure below. 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. To track the sun i used four ldc sensors and arduino compares the data from them to rotate the panel in the direction with the most sunlight using two dc motors one for each axis and motor driver.
