Abstract

The invention concerns a solar collector (10) which has at least one radiation-transmitting prism (16) which is wedge shaped in cross section. The prism has major side surfaces (20, 21) converging at an acute angle to a relatively narrow, operatively upper end (24). The opposite, lower end (26) of the prism is wider. A refractor (18) is arranged over the prism to refract solar radiation incident thereon onto the major side surfaces of the prism, as the sun moves relative to the earth, at angles allowing such radiation to enter the prism and be internally reflected therein towards a target at or adjacent the relatively wide end of the prism. The configuration allows high levels of solar concentration to be achieved.
