Sun Tracking Solar Panel Circuit Diagram

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

Sun tracking solar panel circuit diagram.

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. The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.

A careful investigation of the circuit shown in the diagram reveals that the whole configuration is actually very simple and straightforward. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma. Use of a solar tracker circuit in the field of energy production will increase its efficiency by almost 25. This article describes about circuit that rotates solar panel.

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. 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. So solar panel should continuously rotate in the direction of sun. Generally solar panels are stationary devices which is fixed at a position.

Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun. Light dependent resistors produce low resistance when light falls on them. Circuit diagram the circuit design of solar tracker is simple but setting. 1 shows the circuit of the solar tracking system.

These provide the signal to motor driver ic2 to move the. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. How the solar tracker opamp control circuit functions. This solar tracker system is used for tracking the sun only in one plane the horizontal one.

For the above procedure a different set of ldrs are used and are mounted horizontally over the panel at a specific position as shown in the diagram. In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. The servo motor connected to the panel rotates the panel in the direction of sun. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.

The detailed instructions include the circuit diagram an explanation of how the circuit works a description of how single axis sun tracking works and advice for selecting a dc gearhead motor.
