A reflective solar tracking system of the type arranged to reflect light rays from the sun onto a remote solar energy collector is described. The system comprises a reflector mounted on an assembly incorporating a drive mechanism for rotating the reflector about two axes to compensate for altitudinal and azimuthal changes in the position of the sun. A sensor device is adapted to point at the sun and provide control signals to the drive mechanism so that the reflector is moved in response to solar movement such that sunlight is always reflected onto the collector and at the same time the sensor device is moved so as to track the sun.

A reflective solar tracking system for reflecting light rays from the sun onto a remote solar energy collector, the system comprising: a reflector for reflecting light rays from the sun onto said collector; a mounting assembly for mounting said reflector relative to said collector so that said reflector is rotatable about a first axis pointing at the collector, and about a second axis transverse to the first for controlling elevational tilt of said reflector; sensor means for pointing at the sun and sensing directional changes in the sun\s position, said sensor means including means for producing control signals in response to said directional changes; said mounting assembly including means for mounting said sensor means so that it is rotatable about said first axis to control its azimuthal pointing direction and about a third axis parallel to said second axis for controlling its altitudinal pointing direction; and a drive mechanism for rotating said reflector and sensor means about the respective axes of rotation in response to said control signals so that said sensor means tracks the sun and said reflector moves so as to reflect light rays from the sun onto the collector; said mounting assembly comprising a cylindrical member adapted to be fixed in position to point along said first axis through the center of the plane of said reflector, and a sleeve rotatably mounted on said member, a mounting shaft for said reflector extending transversely along said second axis through said sleeve and being secured to said reflector on opposite sides of said sleeve, said shaft being rotatably mounted in said sleeve to control tilt of said reflector, said reflector having an opening extending transverse to said shaft through which said sleeve projects to point at said collector.
