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.

Sun tracking solar panel circuit diagram. This article describes about circuit that rotates solar panel. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. The solar tracker uses a combination of three photo resistors not photo transistors or ldr s light dependent resistor r7 r8 and r9 to ensure that the circuit will follow the sun during the day but not look for it at night. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.

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. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma. The ldr s are approximately 150 ohms in full sunlight and about 5k in the shade but that is not absolutely. 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.

The two panels cancel out when the sun is equally on both. A careful investigation of the circuit shown in the diagram reveals that the whole configuration is actually very simple and straightforward. Generally solar panels are stationary devices which is fixed at a position. The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.

These provide the signal to motor driver ic2 to move the. How the solar tracker opamp control circuit functions. The produced electrical energy can be increased if we move the solar panel as the movement of the sun. This solar tracker system is used for tracking the sun only in one plane the horizontal one.

Principle of sun tracking 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. Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun. These two east west panels are wired in a short circuit mode.

1 shows the circuit of the solar tracking system. So solar panel should continuously rotate in the direction of sun. The accute angle between. If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit.

The full circuit is shown below. This accute angle is ideal for strength it limits the short circuit losses see below and sets the approx 15 tracking accuracy.
