Solar Sun Tracker Circuit Diagram

We all know.

Solar sun tracker circuit diagram.

Circuit diagram the circuit design of solar tracker is simple but setting. The ldr s are approximately 150 ohms in full sunlight and about 5k in the shade but that is not absolutely. Circuit of solar tracking system. This solar tracker system is used for tracking the sun only in one plane the horizontal one.

The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components. 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. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board. This kit is perfect for the person that wants a quick start on building a single axis solar tracker.

1 shows the circuit of the solar tracking system. 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. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position. 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.

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

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 efficiency of a solar panel system can be improved if the panels track the sun and remain as long as possible at the most favorable angle of incidence. 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.

In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. The heart of the above circuit is two voltage comparators made using lm358 dual op amp. The light detected by the eastward facing sensor is at a lower intensity to that detected by the. The circuitry required is relatively simple.

Solar tracking system circuit fig. In fact solar panels that track the sun create around 30 more energy per day than a fixed panel.
