Sun Tracking Solar Panel Mini Project

The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.

Sun tracking solar panel mini project.

A solar panel is used to harness solar energy. Solar trackers are typically used for ground mounted solar panels and large free standing solar installations like solar trees. Sun tracking solar panel using arduino project is based on arduino controller board which controls the various activities of the project. This project orients the solar panel toward the sun so that it can utilize with higher accuracy.

Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun. This motor is electrically connected to the controller board. The tracking system will move the solar panel so that it is positioned perpendicular to the sun for maximum energy conversion at all time. 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.

These provide the signal to motor driver ic2 to move the solar panel in the sun s direction. The designed project aims at tracking the sun to achieve the maximum sun light incident on the solar panel during anytime of the day. The project is useful during cloudy days. 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.

The sun trackers are all weather reliable and affordable tracking and positioning instruments. 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. 1 shows the circuit of the solar tracking system.

The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller. Two light dependent resistors are arranged on the edges of the solar panel. A solar tracking system maximizes your solar system s electricity production by moving your panels to follow the sun throughout the day which optimizes the angle at which your panels receive solar radiation. Thus the tracking of the sun s location and positioning of the solar panel are important.

In this project i will show you how to create a solar tracker which like the name implies can follow the movement of the sun throughout the day. The system periodically checks the availability of solar energy from one horizon to other horizon periodically. And at the end i will show you the energy harvest difference between a solar tracker mounted solar panel and a flat mounted solar panel.
