Abstract
Abstract A solar powered display device comprising a housing, a generally transparent cover, a solar panel disposed within the housing in planar parallel position with respect to the transparent cover, a battery disposed within the housing and electrically interconnected with the solar panel so as to facilitate charging of the battery via the solar panel, and an illuminator disposed within the housing so as to illuminate display indicia, the illuminator being in electrical communication with the solar panel and the battery so as to receive electrical power therefrom. The display indicia are formed upon plates removably disposed within the housing in planar parallel position with respect to the transparent cover, each plate preferably having a character or the like formed thereupon. A rack is configured to hold plates of a plurality of different sizes.
