Abstract: Solar Energy Powered Address Identifier is a solar powered sign equipped with a backlight and a channel or other means for insertion or display of a set of numbers representing a home or business address. To use Solar Energy Powered Address Identifier, a user chooses a location on a house or other structure that is easily viewed from the street and not obscured by any trees, shrubbery or other impediments. He then attaches the sign to the structure in the selected location. The sign typically utilizes solar power to provide power to the backlighting unit and illuminate the numbers. Sensors on the sign also permit the backlighting to intensify when car headlights or the like contact the sensors.
