Abstract: A thermoelectric generator panel and heater device is disclosed. A heater element is disposed along the normally cool side of a solar panel, comprised of a substantial plurality of substrate strips carrying a plurality of thermocouples, printed in series, and in metallic inks, along one side of the respective strips. Terminal tabs are provided on opposed ends of each strip of thermocouples which are electrically interconnected, in parallel, and a voltage regulator, connected between the panel strips and a heater device, monitors the voltage to maintain a predetermined voltage, 12 volts for example.
