Aim of the project.
Sun tracking solar panel using arduino circuit diagram.
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 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.
This article describes about circuit that rotates solar panel.
The produced electrical energy can be increased if we move the solar panel as the movement of the sun.
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.
Circuit diagram the circuit design of solar tracker is simple but setting.
Arduino solar tracker circuit diagram.
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 sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.
We have designed a single axis solar tracking system.
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.
This is useful for zero pcb or breadboard circuit.
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.
Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun.
This solar tracker system is used for tracking the sun only in one plane the horizontal one.
In this project we are going to show you how to make an arduino based solar tracker using ldr servo motor.
Generally solar panels are stationary devices which is fixed at a position.
Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino.
So solar panel should continuously rotate in the direction of sun.
The circuit diagram shown below.
Pcb design for arduino solar tracker.
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.
Principle of sun tracking solar panel.
In the circuit two ldr light dependent resistors sensors are used to sense the light.
In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun.
