CALCULATION AND INSTALLATION OF BATTERIES FOR SOLAR PHOTOVOLTAIC SYSTEMS
Abstract
This project explores the methodologies and practical considerations involved in integrating battery storage systems with solar photovoltaic (PV) installations. It addresses the challenge of solar energy intermittency by developing accurate battery sizing techniques and efficient installation procedures. The study includes data collection, load analysis, site assessment, environmental evaluation, and Battery Management System (BMS) integration to ensure system reliability and safety. Through detailed calculations, a 5 kVA Solar PV system was designed using 12V/240Ah batteries connected in series, achieving a stable 56.8V at 28% inverter load and providing a full day backup capacity. The findings demonstrate that well-sized and properly installed battery systems significantly improve energy reliability, reduce operational costs, and support sustainable energy adoption. The work concludes that effective solar-plus-storage integration is vital for advancing clean, efficient, and dependable renewable energy solutions.
