A solar collector includes an elongated heat exchange element onto which the sun's rays are to be directed. A compound concentration lens system is mounted to direct the sun's rays onto the heat exchange element and includes a center refractor extending the length of the element for refracting the sun's rays onto the portion of the surface of the heat exchange element facing the sun. A pair of reflectors extend on each side of the refractor, said reflectors each having a plurality of parallel prisms arranged one above the other for reflection of light onto the sides of the heat exchange element. 1 claim, 2 figures.
