Solar Tracking System Circuit Diagram

Pcb design for arduino solar tracker.

Solar tracking system circuit diagram. These provide the signal to motor driver ic2 to move the solar panel in the sun s direction. This article describes about circuit that rotates solar panel. Controller then takes the decision according. This is useful for zero pcb or breadboard circuit.

The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller. 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. Circuit diagram simple solar tracker circuit diagram working. This solar tracker system is used for tracking the sun only in one plane the horizontal one.

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. Circuit of solar tracking system. Circuit diagram the circuit design of solar tracker is simple but setting. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino.

Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. Above can be solved by our system by automatic tracking the solar energy. The heart of the above circuit is two voltage comparators made using lm358 dual op amp. 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. 1 shows the circuit of the solar tracking system the solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. Single axis solar tracking is great for projects such as solar optical concentrators solar ovens fresnel lenses and solar electric photovoltaic panels. 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.

In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system. 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. 1 shows the circuit of the solar tracking system. Arduino solar tracker circuit diagram. If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit.

We all know. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma. In the circuit two ldr light dependent resistors sensors are used to sense the light.
