An economic analysis of residential photovoltaic systems with lithium
Since a 5 kW PV system with 7 kWh of battery storage is near the optimum LCOE sys for PV-battery systems in the three locations considered so far, and because 5 kW is a typical size for residential PV systems in the U.S. , we show LCOE sys and the bi-directional metering parity sell-back price for these parameters for every state in the U.S
