<sup>A solar energy storage system refers to a combination of solarpanels and energy storage technology that allows for the captureconversion, and storage of solar energy for later use. Here's somemore information about solar energy storage systems:
1. Solar Panels: The system begins with solar panels, also knownas photovoltaic (PV) panels, which convert sunlight intoelectricity. Solar panels consist of multiple solar cells madefrom semiconductor materials, typically silicon. When sunlighthits the solar cells, it creates a flow of electrons, generatingdirect current (DC) electricity.
2. Inverter: The DC electricity produced by the solar panels needsto be converted into usable alternating current (AC) electricitybefore it can power household or commercial appliances. Aninverter is used to perform this conversion. Inverters also allowfor the synchronization of solar energy with the utility grid,enabling you to feed excess energy back to the grid or drawelectricity from the grid when needed</sup>

• <sup>3. Energy Storage System: In a solar energy storage system, anenergy storage component, typically a battery, is integrated tostore excess electricity generated by the solar panels. Thestored energy can be used during periods of low sunlight orduring power outages. Lithium-ion batteries, such as lithiumiron phosphate (LiFePO4) or lithium nickel manganese cobaltoxide (NMC) chemistries, are commonly used in solar energystorage systems due to their efficiency, high energy density,and long cycle life.
  4. Battery Management System (BMS): A solar energy storagesystem includes a battery management system (BMS) tomonitor and control the battery's charging and dischargingprocesses. The BMS ensures safe operation, preventsovercharging and over-discharging, balances the cells withinthe battery, and provides information on the battery's state ofcharge.</sup>
