Maintaining a solar power module

A method for cooling a solar power system, comprising:

• operating a solar power system that comprises a plurality of solar power cells mounted on a spherical frame that comprises an inner surface that defines an interior volume;
• generating a magnetic field within the interior volume of the spherical frame with at least one permanent magnet;
• transferring heat from an outer surface of the spherical frame to a magnetized fluid within the interior volume, the magnetized fluid comprising a ferrofluid that includes a plurality of magnetized particles;
• and
• circulating, with a magneto-caloric pump, the magnetized fluid within a plurality of flowpaths defined by a plurality of baffles coupled to the inner surface of the spherical frame within the interior volume and oriented around the inner surface of the spherical frame along a circumference of a cross-section of the spherical frame based, at least in part, on the generated magnetic field caused by the permanent magnet, and (ii) an amount of heat transferred from a heat source that comprises the plurality of solar power cells mounted on the outer surface of the spherical frame into the magnetized fluid.
