Battery systems experience a decrease in charge capacity (energy capacity) over time. This degradation rate is influenced by various factors and may differ based on the technology used. While batteries in most lithium iron phosphate systems may endure for 20 years, they are unlikely to retain 100% charge capacity throughout this period.
In standalone microgrids, the Battery Energy Storage System (BESS) is a popular energy storage technology. Because of renewable energy generation sources such as PV and Wind Turbine (WT), the output power of a microgrid varies greatly, which can reduce the BESS lifetime. Because the BESS has a limited lifespan and is the most expensive component in a microgrid,

If this is the case, the microgrid''s solar panels will instead switch to battery storage (energy storage system). If prices rise, the microgrid controller may switch to discharging its batteries (or other distributed energy resources (DERs) rather than source power from the utility grid.
