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.

In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. A careful investigation of the circuit shown in the diagram reveals that the whole configuration is actually very simple and straightforward. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.

So solar panel should continuously rotate in the direction of sun. 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.

This article describes about circuit that rotates solar panel. The servo motor connected to the panel rotates the panel in the direction of sun. 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.

Principle of sun tracking solar panel. Circuit diagram working the sun tracking solar panel consists of two ldrs a solar panel and a servo motor. 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. If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit.

The produced electrical energy can be increased if we move the solar panel as the movement of the sun. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Generally solar panels are stationary devices which is fixed at a position. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma.

These provide the signal to motor driver ic2 to move the.
