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.
Solar panel battery bank lifespan.
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.
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 round trip efficiency of a solar battery represents the amount of energy you can use from your solar battery compared to the amount of energy it took to store that energy.
1 home energy storage lets you keep the excess electricity your solar panels produce during the day and use it when you need it most such as back up power during a power outage at night or when utility rates.
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.
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.
According to recent data 7 out of 10 solar panel shoppers express interest in adding a battery to their solar systems.
