A solar module comprising a solar cell string laminated between layers of pottant material and a transparent superstrate and a steel substrate. The steel substrate is roll formed to provide stiffening flanges on its edges while simultaneously forming a pan-shaped structure to hold other portions of the laminate in position during the laminating process. An improved terminal provides high voltage protection and improved mechanical strength. A conduit element provides protected raceways for external wires connected to module terminals.

Roll formed pan solar module

A stable ferrofluid composition which comprises a colloidal dispersion of finely-divided magnetic particles in a liquid, low-pressure, polyphenyl ether carrier and a dispersing amount of a surfactant, which surfactant comprises a polyphenyl ether surfactant containing a functional group, such as an acidic group, and an aromatic tail group which is soluble in the polyphenyl ether carrier, to provide a stable ferrofluid composition.
