The circuit design for the system would be.
Dual axis solar tracking system circuit diagram.
Single axis type and dual axis type.
Solar tracking system circuit fig.
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.
Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.
At maximum the solar tracker is perpendicular to the light source.
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.
Pcb layout on desktop fig.
If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit.
The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
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.
For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma.
The heart of the above circuit is two voltage comparators made using lm358 dual op amp.
The solar tracking system can theoretically be divided into 2 types of rotation i e.
Dual axis solar tracker project is to provide an efficient solar distributed generation system.
This solar tracker system is used for tracking the sun only in one plane the horizontal one.
1 shows the circuit of the solar tracking system.
