Solar Tracking System Circuit Diagram

Single axis solar tracking is great for projects such as solar optical concentrators solar ovens fresnel lenses and solar electric photovoltaic panels.

Solar tracking system circuit diagram.

Solar tracking system circuit fig. 1 shows the circuit of the solar tracking system. Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino. Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board.

Circuit of solar tracking system. Arduino solar tracker circuit diagram. Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun. For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma.

If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit. Circuit diagram simple solar tracker circuit diagram working. 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 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. Controller then takes the decision according. Pcb design for arduino solar tracker. 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.

In the circuit two ldr light dependent resistors sensors are used to sense the light. We all know. This article describes about circuit that rotates solar panel. The heart of the above circuit is two voltage comparators made using lm358 dual op amp.

In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun. Principle of sun tracking solar panel. The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system. The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.

These provide the signal to motor driver ic2 to move the solar panel in the sun s direction. 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. The circuit diagram shown below. 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. Circuit diagram the circuit design of solar tracker is simple but setting. This is useful for zero pcb or breadboard circuit.
