When evaluating whether and what type of storage system they should install, many customers only look at the initial cost of the system — the first cost or cost per kilowatt-hour (kWh).

Q = amount of charge stored when the whole battery voltage appears across the capacitor. V= voltage on the capacitor proportional to the charge. Then, energy stored in the battery = QV. Half of that energy is dissipated in heat in the resistance of the charging pathway, and only QV/2 is finally stored on the capacitor.
