The results indicate that the highest gain from energy storage to the share of self-consumed PV electricity is obtained, when the storage to PV capacity ratio is in the range of r = 0.5–2 WhW p−1 irrespective of climate.

The energy storage system can relieve the mismatch between PV generation and electricity load and raise the PV self-consumption ratio (SCR). In particular, the battery energy storage system (BESS) can directly store electrical energy and achieve peak shifting and price arbitrage when the battery is connected to the grid [ [4], [5], [6] ].

Simply put, a solar-plus-storage system is a battery system that is charged by a connected solar system, such as a photovoltaic (PV) one. In an effort to track this trend, researchers at the National Renewable Energy Laboratory (NREL) created a first-of-its-kind benchmark of U.S. utility-scale solar-plus-storage systems.

LCOE is a incomplete metric for evaluating PV plus storage because of the significant increase in value associated with storage—benefit/cost ratio is an alternative metric that accounts for the added value. Coupling by co-locating storage and solar can decrease the overall net costs of deploying PV and storage (AC coupling).
