Solar Sun Tracker Circuit Diagram

This kit is perfect for the person that wants a quick start on building a single axis solar tracker.

Solar sun tracker circuit diagram.

Circuit diagram simple solar tracker circuit diagram working. The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system. If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit. 1 shows the circuit of the solar tracking system.

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. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma. Above is a simplified schematic diagram of a vertical axis solar tracker fitted to a solar panel located in the uk high latitude northern hemisphere. The heart of the above circuit is two voltage comparators made using lm358 dual op amp.

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 circuitry required is relatively simple. The ldr s are approximately 150 ohms in full sunlight and about 5k in the shade but that is not absolutely. The light detected by the eastward facing sensor is at a lower intensity to that detected by the.

The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. The single most simple way of getting more energy out of a solar panel is to have it track the sun. A pair of sensors typically a type of cadmium sulphide photoresistor or leds are used point to the east and west of the location of the sun. In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun.

With that kind of power increase you d think everyone would be doing it but there are some good reasons why it s not overly common. We all know. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.

This solar tracker system is used for tracking the sun only in one plane the horizontal one. 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 fact solar panels that track the sun create around 30 more energy per day than a fixed panel. Circuit diagram the circuit design of solar tracker is simple but setting.

Circuit of solar tracking system. Lt uses a window comparator which keeps the drive motor idle as long as the two ldrs are subjected to the same illumination.
