Automatic Solar Tracking System Circuit Diagram

Circuit of solar tracking system.

Automatic solar tracking system circuit diagram.

Circuit diagram the circuit design of solar tracker is simple but setting. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. This article describes about circuit that rotates solar panel. Here is a simple low cost solar tracker circuit which automatically moves the solar panel in the direction of sun.

Circuit diagram simple solar tracker circuit. This is useful for zero pcb or breadboard circuit. Solar tracking system circuit fig. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.

If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit. So solar panel should continuously rotate in the direction of sun. 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.

The movement of the sun is detected using two ldrs which are arranged on the solar panel in such a way that the intensity of light falling on it varies as the direction of sun changes. This solar tracker system is used for tracking the sun only in one plane the horizontal one. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma. Controller then takes the decision according.

The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. How the dual axis solar tracker concept works the device is able to track the daytime motion of the sun precisely and shift in the vertical axis accordingly. The block diagram below shows system architecture it consist of a ldr sensor senses max solar power which is being given to the microcontroller through the adc which digitizes the ldr output.

The circuit diagram shown below. Construction of single axis automatic solar tracking system. In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun.
