A combined solar daylighting system and photovoltaic electric generation system operates when daylighting both is and is not required. A photovoltaic (PV) array is mounted on the back side of a secondary reflector of the daylighting system with the secondary reflector hinged in such a way that, when sunlight is not needed, the PV array can be positioned to collect the concentrated solar radiation from the primary reflector and convert it into electrical energy. When sunlight is needed for daylighting, the PV array on the back of the secondary reflector receives unconcentrated solar radiation, thereby converting it to electrical energy, though not in as large a quantity as when receiving concentrated solar radiation from the primary concentrating reflector in solar-only mode.
