What are the types of solar batteries? 

There are three main types of solar batteries, each featuring different chemical compositions: lithium ion, saltwater, and lead acid. Here’s what characterizes each of these three battery types: 

What are the types of solar batteriesLead acid 

Although this type of battery is relatively inexpensive and has been used for decades in off-grid solar systems, it has several drawbacks compared to lithium batteries. For starters, these solar batteries have a shorter lifespan than other options

Additionally, their depth of discharge, or DoD for short, is significantly lower than that of lithium-ion batteries. This means that lead acid batteries are able to discharge less power relative to their full capacity in kilowatt-hours. 

Lithium-ion 

Lithium-ion batteries are the standard choice for home solar storage systems. This is because lithium batteries are more compact and lightweight than the other available options. Not only that but they also have higher DoD and longer lifespans than a standard lead acid battery. 

Due to high demand, lithium-ion home batteries have become less expensive than they once were, which makes them much more affordable and attainable to homeowners. 

Saltwater

Saltwater batteries are the newest energy storage technology available on the market. These batteries are more eco-friendly than their alternatives since they don’t contain any heavy metals and are easily recycled. They rely exclusively on saltwater electrolytes to store the power produced by your panels. Unfortunately, these batteries are still somewhat untested, being a relatively new technology.  

What is the best type of solar battery?

What is the best type of solar batteryAlthough lead acid and saltwater batteries may be a good choice for some homeowners, lithium-ion home batteries are by far the best choice for a home solar system. The main reason for this is that lithium-ion battery charge will last longer compared to the two alternatives. Another benefit is that these batteries are more compact and tend to have longer lifespans and higher depth of discharge. 

Even though most experts would suggest lithium-ion batteries, that doesn’t mean that you should make the decision based on what you read online alone. Instead, contact your favorite solar technicians and discuss your needs and options with them. They will carefully evaluate your energy consumption and budget to help you make the best decision based on your specific circumstances.
