Sun Tracking Solar Panel Without Microcontroller

Today we are living in an era where we need to use renewable energy as much as possible because day by day the pollution is increasing. So one of the most usable and efficient renewable energy source is solar panel or solar energy. We have already seen a lot of solar panel systems like static solar panel and sun tracking solar panel. Sun tracking systems are mainly of 2 types, one is single axis solar tracker and dual axis solar tracker. Already many paper has been published on different types of solar panels and already seen the latest one is sun tracking system based on microcontroller. In our project we are trying to make a sun tracking scalable system without microcontroller which can be cheaper than other solar panel circuits in our approach. We hope that this proposal of our system can be efficient in future. This paper proposes a solar system which can track the sun using the reference of two small solar panel and track the path by tracking the difference of two voltages of two reference panels and moves the system structure using stepper motor.
