An energy storage system’s suitability will be chosen based on the specific needs and limitations of the PV or wind power system in question, as well as factors, such as cost, dependability, and environmental impact. Table 8 summarizes the key features and characteristics of energy storage systems commonly used for photovoltaic and wind systems.
As an integrated system, it is difficult to meet the demands in energy density and power density if the optimization is solely applied to the active materials or electrolytes. The photorechargeable battery is an energy storage device, in which both generation of light-excited charge carriers and electrochemical reaction proceed simultaneously.
Based on the study, it is concluded that different energy storage technologies can be used for photovoltaic and wind power applications.
Currently, solar cells are considered as the individual devices for energy conversion, while a series connection with an energy storage device would largely undermine the energy utilization efficiency and peak power output of the entire system.
