If you want to track the solar light in the vertical plane you need to build a separate sun tracker circuit.
Dual axis solar tracking system circuit diagram.
The circuit and the mechanism explained in this article may be considered as the easiest and perfect dual axis solar tracker system.
The solar tracking system can theoretically be divided into 2 types of rotation i e.
The circuit design for the system would be.
Pcb layout on desktop fig.
Circuit of solar tracking system.
At maximum the solar tracker is perpendicular to the light source.
Solar tracking system circuit fig.
The heart of the above circuit is two voltage comparators made using lm358 dual op amp.
Circuit diagram simple solar tracker circuit diagram working.
These tracking systems can employ different input measurement devices that can be categorized into active and passive tracking systems 14 16.
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.
We all know.
Light dependent resistors ldr1 through ldr4 are used as sensors to detect the panel s position.
Circuit implementation of dual axis solar tracker system.
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.
1 shows the circuit of the solar tracking system.
For solar panels control is best to use small motors with a suitable voltage and a maximum working current of 300 ma.
The solar tracker comprises comparator ic lm339 h bridge motor driver ic l293d ic2 and a few discrete components.
