Study and Design of a Hybrid Solar Power System Applicable for a Urban / Rural House in Bangladesh

Abstract

The Hybrid Solar Power System for residential applications is designed to provide a reliable, efficient, and sustainable source of electricity by combining solar photovoltaic (PV) energy with conventional grid power or battery storage. This project focuses on maximizing energy utilization from renewable sources while ensuring uninterrupted power supply during low-sunlight conditions or grid failures. The system integrates solar panels, a charge controller, an inverter, and a hybrid management unit that automatically switches between solar, battery, and grid power based on availability and demand. Real-time monitoring is implemented to track energy production, consumption, and battery status, enhancing system performance and user awareness. By reducing dependency on the main grid and optimizing the use of clean energy, the hybrid system significantly lowers electricity bills and carbon emissions. This project demonstrates a practical solution for households, especially in areas with frequent power outages or high energy costs. The hybrid configuration ensures efficiency, reliability, and long-term sustainability, making it a versatile option for modern smart homes. Overall, the system highlights the potential of renewable energy integration to promote cleaner and more resilient residential power infrastructures.
