This article presents the design and development of a novel and innovative off-grid solar photovoltaic system with supercapacitor-battery hybrid energy storage, which is a part of an ongoing research at the Department of Physics and Electronics. The supercapacitor is a short-term energy storage device compared with electrochemical batteries. In this novel approach, we used the unique characteristics of supercapacitors to enhance the efficiency of off-grid solar photovoltaic systems. From the theoretical and experimental results observed from the developed system prototype, it was shown that the efficiency is enhanced by a further 8% compared with conventional systems.
