A solar collector panel which can also be utilized to display information and/or images and/or messages and having an external frame, with a transparent upper panel securely positioned within the frame. A lower panel is positioned within the frame and spaced in relation to the upper panel so as to provide a closed chamber between the upper panel and the lower panel, an upper surface of the lower panel having applied thereon heat conversion means for converting solar radiation to heat energy, the heat conversion means providing thereon information, an image or message which is visible above the upper surface of the upper panel. A back panel is positioned within the frame, so as to define a closed volume of air space between the lower panel and the back panel through which air may flow. Intake and exhaust pipes introduce air into the frame, and transfer heated air from the frame.
