A solar panel system 10 comprises a fixed solar panel 12 located to receive sunlight from a first direction A, and a light guidance device 15 comprising; an inlet 16 which in use is directed in a second substantially opposite direction B, for receiving sunlight and an outlet 18 for projecting light towards the solar panel. The light guidance device may comprise one or more reflective surfaces (e.g. mirrors, prisms). Where mirror(s) are used, powered pivoting means may be provided to tilt the mirror(s) about one axis or two or more orthogonal axes. In one embodiment, the light guidance device may be moved from an operative condition substantially overlying the panel to an inoperative condition alongside the panel. Alternatively, the device may be pivoted with respect to the panel whilst the device and panel remain in equidistant parallel planes. Actuators may be incorporated to effect said movement of the device. |
