A photovoltaic power generation system that includes a steerable light receiver with one or more photovoltaic cells for collecting light, and a supplementary light source operable to provide supplementary light under predetermined conditions. The receiver is steerable to a docking position at which the light receiver can receive light from the supplementary light source, whereby the supplementary light source can replace or augment natural light so that the power output of the system can be augmented when levels of natural or ambient light are inadequate. |
