Solar Panel Battery Bank Lifespan

If you install a solar battery today you will likely need to replace it at least once to match the 25 to 30 year lifespan of your pv system.

Solar panel battery bank lifespan.

Temperature maintenance and how deeply you discharge your batteries known as depth of discharge all play a serious role in their lifespan either keeping them going as long as possible or helping them conk out after just a few years. Battery technology though isn t the only thing that affects solar batteries lifespan. According to recent data 7 out of 10 solar panel shoppers express interest in adding a battery to their solar systems. So let s say your solar panels had 10 kwh of electricity to send into your battery but you only have 8 kwh of electricity that can be used.

The lithium batteries we use are purpose built for off grid solar and utilize a special lithium chemistry called lithium ferro phosphate lifepo4 commonly called lfp. However just as the lifespan of solar panels has increased significantly in the past decade it is expected that solar batteries will follow suit as the market for energy storage solutions grows. Because of the better efficiency and deeper discharge depth lithium battery banks tend to be only 50 60 of the size of a comparable lead acid bank.
