The size of a capacitor affects how much charge it can store (its capacitance), its voltage rating, and its physical ...

Storage elements that buffer energy of the most diverse forms, and make it available for subsequent conversion processes, are significant components in modern power supplies and frequency converters.

This solar clock was built using a lot of salvaged parts. We find it interesting that [Nereus] combined a ring of storage capacitors with a power cell (translated) to create a hybrid energy storage ...
