Lithium Batteries

Batteries for solar energy storage are evolving rapidly and becoming mainstream as the transition to renewable energy accelerates. Until recently, batteries were mostly used for off-grid solar systems but the huge leap forward in lithium battery technology has seen an immense amount of interest in people wanting to store excess solar energy, increase self-consumption and become more energy independent. Additionally, with frequent extreme weather events causing grid-wide blackouts, households and businesses are looking for ways to ensure they have a reliable electricity supply during prolonged electricity supply disruptions. In this article, we explain some of the advantages and disadvantages of home battery systems, provide a battery cost guide, present some alternative options to using batteries, and present a detailed comparison of the leading battery storage systems used in both off-grid and on-grid solar systems. For those new to solar, you can learn more about the basics of solar and the various energy systems including grid-tie, off-grid and hybrid battery systems.
