Automatic Solar Tracking System Circuit Diagram

Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino.

Automatic solar tracking system circuit diagram.

Circuit diagram simple solar tracker circuit. Above can be solved by our system by automatic tracking the solar energy. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.

So solar panel should continuously rotate in the direction of sun. In the circuit two ldr light dependent resistors sensors are used to sense the light. In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. 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.

If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma. Circuit diagram the circuit design of solar tracker is simple but setting. The circuit diagram shown below.

This article describes about circuit that rotates solar panel. The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system. Construction of single axis automatic solar tracking system. Controller then takes the decision according.

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

Circuit of solar tracking system. This solar tracker system is used for tracking the sun only in one plane the horizontal one. Pcb design for arduino solar tracker. Principle of sun tracking solar panel.

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 is useful for zero pcb or breadboard circuit.
