What are solar batteries?

Solar batteries are usually lithium-ion batteries that store solar energy captured by photovoltaic panels. The panels in the system collect solar energy and convert it to electricity, which is then sent to your home via the inverter. A solar battery is a lithium-ion battery that stores energy from solar panels while the sunlight is abundant. When there's not enough sun to meet your power needs, these batteries can draw on this solar battery storage, preventing a dip in electric grid demand and blackouts. They typically have a larger capacity than their counterparts. In short, these batteries can be used to store electricity as off-grid energy systems, or while there is no electricity available, or when the user demands surplus electricity during periods of high demand. They can often be stacked like a modular battery system or used individually in series with other cells.

How to store your battery?

The battery stays healthy only when you create optimal conditions for it. One of the main elements regarding optimal conditions for making solar batteries last long and well is to maintain them in a cool, protected environment. Indoor use is ideal in order to keep the batteries cool. This will help the accumulation of power and decrease degradation, maximizing the lifespan of a solar battery in the process.

What is the life span of solar batteries in general?

The general period or the life expectancy of most solar batteries is 5-15 years. As mentioned earlier, there are a lot of factors like power rating, system size, DoD, etc, that affect the life of your solar battery today. However, you can expect it to last for the above mentioned period of time. If it lasts more than that then give yourself a pat on your back!
