There is provided solar heat collecting apparatus which comprises a solar collector panel rotatably supported about a horizontal and a vertical axis and drive means for rotating the panel simultaneously about the two axes. The collector panel comprises a battery of individual collector units wherein each collector unit comprises an elongated trough member, a concave reflective surface forming at least a portion of the interior surface of the trough and a fluid carrying pipe extending longitudinally within the trough member, the longitudinal axis of the pipe being substantially coincident with the focal line of the concave reflective surface. The pipe can be formed of a material that is substantially transparent to solar radiation. In addition, there can be a linear focusing lens, substantially covering and extending over the concave reflective surface. The focal line for the linear lens should be substantially coincident also with the longitudinal axis of the fluid carrying pipe.
