Sun Tracking Solar Panel Project Documentation

Introduction since this project is about creating a solar tracker some light dependent circuit element.

Sun tracking solar panel project documentation.

There are two types of solar tracking systems. For flat panel applications trackers are used to minimize the angle of incidence between the incoming light and a solar panel. Our sun tracker system track the sun by use of sensors and rotate the solar panel by means of stepper motor. In fact solar panels that track the sun create around 30 more energy per day than a fixed panel.

The goal of this project is to design an automatic tracking system which can locate position of the sun. Light dependent resistors produce low resistance when light falls on them. 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. The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.

A solar tracker is basically a device onto which solar panels are fitted which tracks the motion of the sun across the sky ensuring that the maximum amount of sunlight strikes the panels throughout the day. The sun trackers are all weather reliable and affordable tracking and positioning instruments. This project orients the solar panel toward the sun so that it can utilize with higher accuracy. The designed project aims at tracking the sun to achieve the maximum sun light incident on the solar panel during anytime of the day.

In this context solar tracking system is the best alternative to increase the efficiency of the photovoltaic panel. The single most simple way of getting more energy out of a solar panel is to have it track the sun. After finding the sunlight the tracker will try to navigate through the path ensuring the best sunlight is detected. A single axis tracker moves your panels on one axis of movement usually aligned with north and south.

The project is useful during cloudy days. The tracking system will move the solar panel so that it is positioned perpendicular to the. With that kind of power increase you d think everyone would be doing it but there are some good reasons why it s not overly common. 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 provide the supply the maximum power.

The system requires a solar panel coupled with a stepping motor to keep tracking the sun and moving according to the maximum sun light received. Solar trackers help to minimize this angle by working to orient panels so that light strikes them perpendicular to their surface. Two light dependent resistors are arranged on the edges of the solar panel.
