Supercapacitors, in particular, show promise as a means to balance the demand for power and the fluctuations in charging within solar energy systems. Supercapacitors have been introduced as replacements for battery energy storage in PV systems to overcome the limitations associated with batteries [79, , , , , ].
The stored energy can be quickly released from the capacitor due to the fact that capacitors have low internal resistance. This property is often used in systems that generate large load spikes. In such cases, batteries cannot provide enough current and capacitors are used to supplement batteries.
