Abstract

The growth in the use of renewable energy sources, such as solar, requires an energy system with greater flexibility to guarantee efficient integration between the generation sources and loads connected to the grid. Energy storage systems (ESS) through electrochemical batteries come up with one of the leading solutions that can provide resilience and reliability in integrating high renewable energy shares into networks. This solution has a great capacity to absorb, retain and then re-inject electricity quickly, in which this response can vary from seconds to milli-seconds depending on the technology. The photovoltaic (PV) market, together with the massive expansion of electric vehicles adoption, has driven the research and development of different types of batteries. This paper presents an overview of the most applied battery technologies in PV systems presenting their main essential characteristics, advantages, and disadvantages. The literature on batteries combined with PV systems was investigated. Thus, it was observed that to select the best type of battery for the application it is necessary, in addition to comparing the technologies, studying the local installation, environmental and operational conditions.
