Abstract
An optical system that allows an image to be displayed on the surface of a solar panel without this image forming an obstacle to direct solar rays. The system includes a solar panel, a lenticular surface formed from linear lenses, and a transparent film on which an image, the straight bands of which, parallel to the longitudinal axis of the lenses, have been removed, is printed. At certain viewing angles, an observer can see only the image bands, whereas at other angles of incidence the sun's rays will pass through the transparent bands and reach the active surface of the solar sensor. The system is particularly suitable for, for example, aesthetic and architectural integration of solar panels, and for disseminating visual information on the surface thereof.
