Abstract

A thin optical panel formed of two, preferably identical, but opposed spaced apart lenticulated plates structured to form a series of regularly spaced apart line images of the sun, one line image for each associated pair of lenticular elements in a plate. All of the line images formed move short distances as a group across a plane behind the panel during the diurnal motion of the sun. The images thus formed can be tracked with an array of thin silicon ribbons or the like to convert solar energy to electrical energy. Two spaced apart panels arranged to move in their own planes relative to one another continuously collimate solar energy emerging from the second panel which thereafter can be focused onto a single silicon ribbon. With the optical axes of the lenticules of the second panel selectively offset with respect to those of the first panel, focusing onto a single silicon ribbon is achieved by the panels themselves.
