The surplus of energy generated using photovoltaic panels is first directed to such a storage facility, and only after it is completely filled is it transferred to the power grid. When photovoltaic modules stop converting solar energy into electricity, the energy necessary to power the devices will come from the energy storage.

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.
At 0.40 $/kWh, the hydrogen-bromine flow battery system is too expensive for grid-level application. It is explained that the high cost is due to hydrogen storage. The costs of the hydrogen-bromine system can be significantly lowered if the costs of the battery stack and power electronics can be reduced.
