Sun Tracking Solar Panel Mini Project

Two light dependent resistors are arranged on the edges of the solar panel.

Sun tracking solar panel mini project. 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. The system periodically checks the availability of solar energy from one horizon to other horizon periodically. A solar panel is used to harness solar energy. These provide the signal to motor driver ic2 to move the solar panel in the sun s direction.

Our sun tracker system track the sun by use of sensors and rotate the solar panel by means of stepper motor. 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. Sun tracking solar panel using arduino project is based on arduino controller board which controls the various activities of the project. 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.

Light dependent resistors produce low resistance when light falls on them. Thus the tracking of the sun s location and positioning of the solar panel are important. 1 shows the circuit of the solar tracking system. For flat panel applications trackers are used to minimize the angle of incidence between the incoming light and a solar panel.

The goal of this project is to design an automatic tracking system which can locate position of the sun. This motor is electrically connected to the controller board. Arduino based sun tracking solar panel project using ldr and servo motor 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. Solar trackers are typically used for ground mounted solar panels and large free standing solar installations like solar trees.

The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun. The sun trackers are all weather reliable and affordable tracking and positioning instruments. The project is useful during cloudy days.

The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller. The tracking system will move the solar panel so that it is positioned perpendicular to the sun for maximum energy conversion at all time. 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.
