The wide range of battery options and energy storage systems can be overwhelming for many people and the rapid pace of technology has resulted in some confusion over which type of battery is best suited to individual needs. Adding to the complexity are the many different battery configurations now available.
Generally, the best way forward is to get advice from a solar company and learn about the different battery options. However, this isn’t always reliable as some companies have limited experience with batteries and are unfamiliar with the many different AC and DC-coupled battery configurations. Fortunately, this is where we can help. The team behind Clean Energy Reviews have been installing and monitoring energy storage systems since 2014 and has some insightful tools and detailed reviews to help you understand what type and size battery is best suited to your needs. That said, many solar professionals are experienced and can offer the best system to suit your needs or what will work best if you already have an existing solar system.
Lead-acid batteries - Traditionally used for off-grid power systems but are not widely used today
Lithium-ion batteries - Now the most common type of battery and advancing rapidly
Flow batteries - Generally used for larger energy storage applications and gradually evolving
Traditional battery systems were made up of deep-cycle lead-acid batteries. However, over recent years, different variations of lithium-ion batteries have dominated due to the many benefits of lead-acid batteries, including lightweight, scalable, high efficiency and long life. Large companies such as LG and Samsung began releasing lithium battery systems back in 2015, but interest rapidly increased with the announcement of the Tesla Powerwall; this was when home storage batteries really hit the mainstream.
