How Does A Solar Battery Work? | Energy Storage Explained

Solar panel companies prefer lithium-ion batteries because they can store more energy, hold that energy longer than other batteries, and have a higher Depth of Discharge. Also known as DoD, Depth of Discharge is the percentage to which a battery can be used, related to its total capacity. For example, if a battery has a DoD of 95%, it can

power supply

Batteries store energy. Power is energy per time. This also means that energy can be expressed as power times time, like the kiloWatt-hours used to express the electric energy your house consumes during a billing period. Another common measure of energy is the Joule. A Watt (a unit of power) is one Joule per second.
