Dual Axis Solar Power Tracking System

Abstract

In the current world, electrical energy has surpassed all other important resources. However, it still hasn't been able to reach every corner of the globe, mainly rural places. Energy production has also come under threat from the quick depletion of fossil fuels and greenhouse gas emissions. As a result, finding other methods of energy generation is crucial. Solar energy is the greatest underutilized renewable energy source and has the potential to meet all of our energy needs entirely. Using solar photovoltaic panels allows for easy exercise. However, it has been noted that the majority of solar panels are positioned at fixed angles. The solar tracking device is used to keep the solar panel towards the sun throughout the day in order to capture as much incident solar energy as possible, increasing the system's performance ratio. The Dual Axis Solar Power Tracker, which combines software programming for the microcontroller unit with hardware design and implementation, can be used to accomplish this. To move two DC gear motors, which spin the solar panel in two axes, the system used an ATmega328P microcontroller. The microprocessor estimates rotating speed based on data collected from four light sensing sensors that are placed strategically close to a solar panel. As a result, solar panels are able to provide more output power.
