Intelligent Cross-axis Solar Power Tracking System

Abstract

The sun is an abundant and powerful renewable energy resource that plays a crucial role in sustainable energy production. With efficient power generation in mind, here is a system designed to make intelligent judgements based on a condition so that the solar panel is always tilted towards the maximum sunlight. The hybrid intelligent cross-axis solar power tracking system is built using the microcontroller, light sensors, solar panel, and motors. Here, there are two methods used namely, the Sun Position Algorithm and the other is using the sensors. The algorithm uses the azimuth angle and the sun’s altitude to identify the position of the sun depending on the geo location. For maximum power generation from the solar panel, we use the sensor-based technique to come into picture whenever the output voltage is less than the fixed threshold voltage using the Sun Position Algorithm.
