Comparing Lithium-Ion and Lead-Acid Solar Energy Storage
While lithium-ion and lead-acid batteries have their pros, each option also comes with a couple of cons, and the best option for you depends on what you want from your battery.
Lead acid batteries for solar energy storage are called “deep cycle batteries.” Different types of lead acid batteries include flooded lead acid, which require regular maintenance, and sealed lead acid, which don't require maintenance but cost more.
Whether you opt for lead-acid or lithium technology, our goal is to help you harness solar power effectively and take control of your energy future. As the energy landscape continues to evolve, the choice between lead-acid and lithium batteries for solar storage will likely become even more nuanced.
Lead acid batteries are proven energy storage technology, but they're relatively big and heavy for how much energy they can store. Deep cycle lithium ion batteries are more expensive than nearly all lead acid batteries, but are much more compact and maintenance-free.
Lead-acid batteries have been a staple in energy storage since the mid-19th century. These batteries utilize a chemical reaction between lead plates and sulfuric acid to store and release energy. There are two primary categories of lead-acid batteries:
