ADVANTAGES AND DISADVANTAGES OF PHOTOVOLTAICS

Advantages and Disadvantages of Chemical Capacitors

Capacitors have a much lower capacity of energy when compared to batteries. This is why batteries are used in applications that will need to supply energy for a longer period. Capacitors are generally used in applications where they will supply energy for a few seconds or less. . Capacitors only have a limited amount of storage. When a capacitor is fully charged it can not take any more energy and the excess voltage is wasted. . Capacitors cannot store charges for long periods of time. Once a capacitor holds energy for long periods of time the level of voltage will start to drop.. . The level of stored voltage in a capacitor can vary. What we mean by this is the amount of energy in a capacitor is not fixed. If voltage is applied to a capacitor for a period of time it may not. [pdf]
