Automatic Solar Tracking System Circuit Diagram

The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system.

Automatic solar tracking system circuit diagram.

In the circuit two ldr light dependent resistors sensors are used to sense the light. This is useful for zero pcb or breadboard circuit. Above can be solved by our system by automatic tracking the solar energy. This solar tracker system is used for tracking the sun only in one plane the horizontal one.

Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. Solar tracking system circuit fig. 1 shows the circuit of the solar tracking system. Controller then takes the decision according.

Arduino solar tracker circuit diagram. So solar panel should continuously rotate in the direction of sun. If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit. Circuit diagram the circuit design of solar tracker is simple but setting.

Principle of sun tracking solar panel. 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. This article describes about circuit that rotates solar panel. In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun.

The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller. Circuit of solar tracking system. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. 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.

Construction of single axis automatic solar tracking system. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. 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.

Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. Automatic solar tracking system with complete project report code and circuit diagram for more detail go to http fantasyelectronisc blogspot in 2013 02 au. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma.
