This solar tracker system is used for tracking the sun only in one plane the horizontal one.
Solar tracking system circuit diagram.
Principle of sun tracking solar panel.
Controller then takes the decision according.
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.
These provide the signal to motor driver ic2 to move the solar panel in the sun s direction.
The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
This is useful for zero pcb or breadboard circuit.
Let us design a solar tracker using two servo motors a light sensor consisting of four ldrs and arduino uno board.
Single axis solar tracking is great for projects such as solar optical concentrators solar ovens fresnel lenses and solar electric photovoltaic panels.
The sun tracking solar panel consists of two ldrs solar panel and a servo motor and atmega328 micro controller.
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.
In the circuit two ldr light dependent resistors sensors are used to sense the light.
If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit.
We all know.
In modern solar tracking systems the solar panels are fixed on a structure that moves according to the position of the sun.
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.
The heart of the above circuit is two voltage comparators made using lm358 dual op amp.
Since ldr is an analogue sensor they are connected to the analog pins a0 and a1 of arduino.
Circuit diagram the circuit design of solar tracker is simple but setting.
Arduino solar tracker circuit diagram.
So solar panel should continuously rotate in the direction of sun.
Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position relative to the sun.
Above can be solved by our system by automatic tracking the solar energy.
1 shows the circuit of the solar tracking system.
Pcb design for arduino solar tracker.
Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.
The circuit diagram shown below.
The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system.
