Lead Acid Batteries vs Lithium Batteries: Which Are Better for Solar?
Lead acid batteries generally have a round-trip efficiency somewhere in the ballpark of 80%. This means that for every 10kWh of energy you put into your battery, you can draw 8kWh back out. Lithium batteries offer an even higher round-trip efficiency, generally around 90% (such as the Tesla Powerwall 2). Lithium batteries are very efficient …

The round trip energy efficiency of a LFP battery is 92%. The charge process of lead-acid batteries becomes particularly inefficient when the 80% state of charge has been reached, resulting in efficiencies of 50% or even less in solar systems where several days of reserve energy is required (battery operating in 70% to 100% charged state).
