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. 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. Lead acid lithium ion and saltwater. Solar panels make more electricity during the middle of the day than they do at any other time of day.

In most cases lithium ion batteries are the best option for a solar panel system though other battery types can be more affordable.
