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.
