Although using energy storage is never 100% efficient—some energy is always lost in converting energy and retrieving it—storage allows the flexible use of energy at different times from when it was generated. So, storage can increase system efficiency and resilience, and it can improve power quality by matching supply and demand.
In this article, we outline the relative advantages and disadvantages of two common solar-plus-storage system architectures: ac-coupled and dc-coupled energy storage systems (ESS). Before jumping into each solar-plus-storage system, let''s first define what exactly a typical grid-tied interactive PV system and an "energy storage system" are.

What is photovoltaic (PV) technology and how does it work? PV materials and devices convert sunlight into electrical energy. A single PV device is known as a cell. An individual PV cell is usually small, typically producing about 1 or 2 watts of power. These cells are made of different semiconductor materials and are often less than the thickness of four human hairs.
Due to the intermittent nature of solar irradiation, it becomes vital to hybridize the PVSCs with electrical energy storage (EES) devices such as Li-ion batteries, capacitors, and supercapacitors (SCs) in one single power unit component.
