A solar powered illuminated sign having at least one interchangable character which comprises a transparent panel mounted centrally across a front wall of a housing. A mechanism is for mounting a character display medium in a removable manner over the transparent panel. A control circuit, a rechargeable battery and a light source are within said housing. The rechargeable battery and the light source are electrically connected to the control circuit. A solar generating unit is mounted onto the front wall of the housing, wherein the solar generating unit is electrically connected to the control circuit. In a first instance during daylight hours, the sun will supply solar energy to the solar generating unit, causing the control circuit to allow charging of the rechargeable battery and deactivate the light source. In a second instance during nighttime hours, the control circuit will allow the rechargeable battery to supply DC electric power to the light source, to illuminate the transparent panel and the character display medium.
