The research aims to investigate the impact of adding multi-solar collector and photovoltaic systems to healthcare facilities, analyze the system's thermodynamic efficiency in terms of energy and exergy, assess its technical and economic viability, and gauge the. . These energy-intensive services offer an excellent opportunity to integrate renewable energy sources and reduce the carbon footprint of healthcare facilities. This study presents a case study of a hospital located in the Gulf Cooperation Council (GCC) that utilizes a solar-collected water-heated. . Sustainability and energy efficiency are essential to every walk of life today, but Solar Panels and Battery Storage for Hospitals are even more crucial where technology is used for everything from diagnostics to treatment and record keeping. With large roof spaces, hospitals, clinics and health. . In this study, the combination of crossover algorithm and particle swarm optimization—crossover algorithm-particle swarm optimization (CS-PSO) algorithm—to optimize photovoltaic hybrid energy storage scheduling, improving global search and convergence speed, is discussed. The new method reduces. .
