It follow the sun according to the intensity of sunlight.
Sun tracking solar panel using arduino uno.
Use an arduino two small servo motors with light sensing photo resistors to steer a solar panel towards the sun.
This instructable will look into how solar trackers work and implement such a method into a solar tracker prototype using an arduino uno.
A solar panel is used to harness solar energy.
An arduino uno used here buy here.
Updated servo controlled light tracking solar panel platform.
Our tracker isa dual axis tracker meaningit tracks in both x and y.
The solar tracker can be controlled automatically with the help of lightdependent resistor ldr sensors or manually using a potentiometer.
The one used in this project is a 9 gram analogue servo.
Every panel you seein your day to day life is in a fixed position.
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.
While this approach isextremely simple and meets the needs of most small applications it isn tproducing as much energy as it could be.
In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun.
To put it into.

Solar is easy to use readily available and inexpensive.

In sun tracking solar system project solar panel follow or track the sun with the help of ldr.
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.
Single axis tracking stand brief diy design shown in step 6 2 x 4 7k resistors buy here.
One way to do this is to have the panels move always facing the sun in the sky.
Sun tracking solar panel using arduino project is based on arduino controller board which controls the various activities of the project.
The specific servo model or size has not been stated as it depends on the size and weight of your solar panel.
Also since a panel which is incident to the sun can gather more amount of solar energy the solar panel is attached to a motor.
Select your favourite project let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board.
Right top right down left down are in the shadow and left top get the most light example2 when the light is on top left and right down are in the shadow and top is in the light.
This allows optimal energy collection making solar panels more efficient.
Example1 when the light is left on top.
