Analysis and Comparison of Charging Time between Battery and Supercapacitor for 300W Stand-Alone PV System

Among the available energy sources the energy through photovoltaic impact can be viewed as the most fundamental and sustainable resource as a result of the all over, sufficient and sustainability of solar radiant energy. Stand-alone solar photovoltaic system consists of storage device which stores the electrical energy in the form of chemical energy, and this system then transforms that energy into electricity. Battery due to its low cost and ease of availability becomes one of the most conventional method of energy storage in all other standalone solar systems. Power generation from the solar photovoltaic system is an efficient energy storage business. Among the best energy storage device Super capacitor has a special place. It consist of unique properties that can praise other energy storage technologies. For factors like less charging time and rapid charging Super capacitors performs better than a conventional battery. It also have a better performance characteristics with improved system efficiency, high power density and discharging capability. The examination and comparison of batteries and super capacitor charging time for solar insolation at constant and time varying state is clearly clarified in this paper. It also explains the output voltage and current through load. Matlab/Simulink environment is used to simulate this 300W dynamic model of stand-alone solar PV system.
