Abstract
A solar energy collector is disclosed. The collector includes a photo-voltaic cell, a reflector for directing solar energy from the sun to the photo-voltaic cell, a mount for the reflector, vacuum means and positioning means for the reflector. The vacuum means separates the photo-voltaic cell and the reflector from the atmosphere to prevent conduction and convection heat losses therefrom and corrosion of the reflector. The mounting means supports the reflector within the vacuum means for rotation about an axis along which the photo-voltaic cell extends. The positioning means is operable to produce a magnetic field which attracts a ferromagnetic portion of the reflector and to rotate the magnetic field about the axis to cause rotation of the reflector and maximizing the amount of solar energy directed to the photo-voltaic cell.
