An inexpensive, highly efficient, durable, and easy to manufacture solar collector of the flat-plate type. The collector includes a heat exchanger having an upper plate, a lower plate, and four triangularly-shaped side plates defining an enclosed chamber, all plates being highly absorbent of solar radiation, the upper plate curving inwardly so that a central portion thereof extends closely adjacent the lower plate along a hot line extending between opposite corners of the collector; and means for conducting a fluid into and out of the chamber, at the remaining corners thereof, on opposed sides of the hot line, so that the fluid flows through the chamber, perpendicular to and in a thin sheet past the hot line, absorbing heat from the upper plate. The collector also includes a frame in which the heat exchanger is supported along the outer edges only in a manner such that light is reflected to the lower plate to increase the efficiency of heat absorption.
