What Are Solar Batteries?

There will be nowhere to store excess power generated by your solar panels if you do not have a solar battery. A solar battery's goal is to store extra energy for use when it is needed, such as during cloudy days when the solar panels are not producing much electricity for the home. If a battery isn't installed in the home, any extra energy produced will be sent back to the grid, essentially sharing electricity to others.

Solar Battery Types

Lead-acid, lithium ion, nickel cadmium, and flow batteries are the four main types of batteries used in solar power. Lead-acid batteries have become an increasingly common option for use in a home solar system. Because of their high energy, lithium-ion batteries are a smaller, lighter, and more efficient solution. Nickel-cadmium is rarely employed in residential settings, preferring instead to be found in aviation and industrial uses. Flow batteries rely on chemical reactions and are therefore better suited to larger spaces or applications.


Battery Life

A battery's lifespan can be impacted by a variety of factors, including type, quality, and depth of discharge. Referring to the battery's manufacturer's specifications might help you determine how long it will last. In general, lead-acid batteries have a lifespan of 1 to 10 years. Lithium-ion batteries typically have a lifespan of 7 to 15 years.

Battery Storage Capacity

When looking for the best storage capacity in a solar battery, it's not just about getting the biggest battery. You must evaluate how much electricity you need on a daily basis as well as how much you want accessible on days when the panels aren't producing enough. It's also worth noting that most solar batteries are stackable, which means you can combine numerous batteries to achieve the precise amount of storage you require.
