A solar power system includes a plurality of solar power cells mounted on an outer surface of a spherical frame, the spherical frame including an inner surface that defines an interior volume; at least one magnet mounted adjacent the outer surface of the spherical frame or within the interior volume of the spherical frame and configured to generate a magnetic field within the interior volume; and a magnetized heat transfer fluid disposed and flowable within the interior volume of the spherical frame based, at least in part, on an amount of heat transferred from the outer surface of the spherical frame into the magnetized heat transfer fluid and the magnetic field.
