In this project we are going to show you how to make an arduino based solar tracker using ldr servo motor.
Sun tracking solar panel using arduino circuit diagram.
We have designed a single axis solar tracking system.
For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma.
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.
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.
This article describes about circuit that rotates solar panel.
Generally solar panels are stationary and do not follow the movement of the sun.
If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit.
Aim of the project.
The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.
The produced electrical energy can be increased if we move the solar panel as the movement of the sun.
Pcb design for arduino solar tracker.
Here is a solar tracker system that tracks the sun s movement across the sky and tries to maintain the solar panel perpendicular to the sun s rays ensuring that the maximum amount of sunlight is incident on the panel throughout the day.
Generally solar panels are stationary devices which is fixed at a position.
Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board.
Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun.
So solar panel should continuously rotate in the direction of sun.
This solar tracker system is used for tracking the sun only in one plane the horizontal one.
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.
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.
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.
This is useful for zero pcb or breadboard circuit.
Circuit diagram the circuit design of solar tracker is simple but setting.
Principle of sun tracking solar panel.
In the circuit two ldr light dependent resistors sensors are used to sense the light.
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.
Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino.
