Influence of a Dual Axis IoT- Based Off-Grid Solar Tracking System and Wheatstone Bridge on Efficient Energy Harvesting and Management

Abstract

Addressing the increasing need for sustainable energy solutions, this study presents an advanced dual-axis solar tracking system tailored for Mirpur, Dhaka, Bangladesh (23.8123° N, 90.3740° E). By integrating Internet of Things (IoT) based intelligent power management and automated panel cleaning, we aim to optimize the efficiency of solar photovoltaic (PV) systems. Our design significantly outperforms traditional fixed PV setups, achieving an average voltage improvement of about 18.59% throughout the day. Real-time data monitoring showcases the system's adaptability, with Solar Voltage (SV) and Solar Current (SC) standard deviations recorded at 1.059 and 0.058, respectively. This system not only captures sunlight more efficiently but also ensures self-maintenance, reducing manual intervention. The integration of IoT capabilities provides real-time feedback and adaptability. With a small household size of 4-6 members and a basic electricity demand as a prototype version, the study reveals promising results for sustainable energy solutions. In future integrating a Microgrid system for improved energy distribution and storage, alongside implementing a smart fuzzy logic-based tracking system to optimize solar panel orientation for maximum power generation.
