Pumps' Perplexities

Am I missing something?.......After an internet
search, I found a solar powered garden
ornament which requires "one AA-Ni Cad
Rechargeable Battery".......

How can something be solar powered if it
needs a double A nickle cadmium rechargeable
battery to run the thing????.....If you need
a battery to operate it, then it is TRULY
NOT solar......Pumps
