  • Roll formed pan solar module
    Patent number: 4433200
    Abstract: 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.
