2.1. Electrical Energy Storage (EES) Electrical Energy Storage (EES) refers to a process of converting electrical energy into a form that can be stored for converting back to electrical energy when required. The conjunction of PV systems with battery storage can maximize the level of self-consumed PV electricity.
Here storage tank is filled with storage material as packing. During storage, HTF heated by solar energy enters from top of the tank and storage materials absorb the heat from HTF. In the discharge, cold HTF enters the bottom of the tank and storage materials release the heat to HTF (Erregueragui et al., 2016, Stutz et al., 2017).
