A solar concentrator, comprising: a reflector assembly comprising first and second reflectors (4,6) fixedly mounted relative to each other, the first and second reflectors (4,6) being configured such that solar radiation incident on the first reflector from a target direction is focussed to a point focus via a first sequence of reflections, the first sequence of reflections including a reflection from the first reflector onto the second reflector and a subsequent reflection from the second reflector onto the point focus, the first reflector comprises a reflective surface shaped as a portion of a cone; said solar concentrator characterized by further comprising: a first tracking assembly comprising first and second connectors (11,12) supporting the reflector assembly, wherein the first and second connectors (11,12) are configured to allow rotation of the reflector assembly about a first axis via pivoting of the reflector assembly at the first and second connectors (11,12); the first and second connectors (11,12) are both located on the first axis and are spaced apart from each other along the first axis; the solar concentrator further comprises a second tracking assembly, wherein the first tracking assembly is connected to the second tracking assembly in such a way as to be rotatable about a second axis that is perpendicular to the first axis; and the first and second axes (18,22) pass through the point focus such that the point focus remains stationary through a range of angles of rotation of the reflector assembly about the first axis and second axis. a reflector assembly comprising first and second reflectors (4,6) fixedly mounted relative to each other, the first and second reflectors (4,6) being configured such that solar radiation incident on the first reflector from a target direction is focussed to a point focus via a first sequence of reflections, the first sequence of reflections including a reflection from the first reflector onto the second reflector and a subsequent reflection from the second reflector onto the point focus, the first reflector comprises a reflective surface shaped as a portion of a cone; said solar concentrator characterized by further comprising: a first tracking assembly comprising first and second connectors (11,12) supporting the reflector assembly, wherein the first and second connectors (11,12) are configured to allow rotation of the reflector assembly about a first axis via pivoting of the reflector assembly at the first and second connectors (11,12); the first and second connectors (11,12) are both located on the first axis and are spaced apart from each other along the first axis; the solar concentrator further comprises a second tracking assembly, wherein the first tracking assembly is connected to the second tracking assembly in such a way as to be rotatable about a second axis that is perpendicular to the first axis; and the first and second axes (18,22) pass through the point focus such that the point focus remains stationary through a range of angles of rotation of the reflector assembly about the first axis and second axis. a first tracking assembly comprising first and second connectors (11,12) supporting the reflector assembly, wherein the first and second connectors (11,12) are configured to allow rotation of the reflector assembly about a first axis via pivoting of the reflector assembly at the first and second connectors (11,12); the first and second connectors (11,12) are both located on the first axis and are spaced apart from each other along the first axis; the solar concentrator further comprises a second tracking assembly, wherein the first tracking assembly is connected to the second tracking assembly in such a way as to be rotatable about a second axis that is perpendicular to the first axis; and the first and second axes (18,22) pass through the point focus such that the point focus remains stationary through a range of angles of rotation of the reflector assembly about the first axis and second axis.
