Lithium battery is selected as the energy storage battery in this paper. According to the “Research Report on Household Energy Storage Industry” (2022), the life cycle of energy storage is 10 years, the unit capacity cost is 175 $/kWh, and the unit power cost is 56 $/kW.
Existing solar systems typically have solar inverters which change the DC power produced by panels to AC power that can be consumed in your home or exported onto the grid. But if you want to store that AC power in a battery, it needs to be inverted again to DC power.
During the day, photovoltaic power firstly supplies the load, then charges the battery, and finally the excess power can be connected to the grid; At night, the battery discharge supplies the load, and the insufficient part is supplemented by the power grid.
