PROBLEM TO BE SOLVED: To restrain a magnetic moment generated in a solar cell panel by a low-cost and lightweight structure by a method wherein a continuity path is provided in the rear of the panel, so as to enable a current which is generated in a large number of solar cells to be supplied to a load to flow therethrough in a direction opposite to the direction in which a current flows through the solar cells. SOLUTION: When solar cells 4 are irradiated with sunlight to generate an electric power, a current flows through each solar cell module 7 from a cathode end to an anode end via an intermediate tap to from a current loop. On the other hand, a current flows through a wiring material 21 bonded to the underside of the solar cell module 7 from an anode end to a cathode end, via an intermediate tap to form a current loop. By this setup, magnetic moments generated by a current loop formed by a current which flows through the solar cell module 7 and another current loop formed by a current which flows through the wiring material 21 bonded to the underside of the above solar cell module 7 are canceled with each other, and as a result a magnetic moment can be almost completely restrained from being generated. |
