An improved solar concentrating system (100) uses a two-stage arrangement of mirrors wherein the rays of the sun are reflected and concentrated to a point focus. The solar concentrator (100) may be used to increase the temperature of a substance such as metal, for use in a variety of applications including the melting of metals in a foundry furnace. The solar concentrating system (100) comprises at least two single-curved parabolic mirrors (10, 20) connected in an operable arrangement. The rays of the sun are reflected from a first single-curved parabolic mirror (10) to a second single-curved parabolic mirror (20). The plane of symmetry of the second single-curved parabolic mirror is arranged substantially orthogonal to the plane of symmetry of the first single-curved parabolic mirror thereby concentrating the rays of the sun to a point focus.
