Magnetic evaluation of a solar panel using HTS-SQUID

• The magnetic evaluation system of a solar panel using HTS-SQUID has been developed.
• The electric circuits made by the discrete devices on the circuit board were visualized.
• The electric properties of the commercial solar panels were demonstrated.

The magnetic evaluation system of a solar panel using HTS-SQUID has been proposed and developed. A normal pick-up coil was applied to detect the tangential magnetic field to the panel surface. Since the detected field could be related to the currents of the solar panels, the electric properties of the solar panels could be evaluated. In this work, the evaluation of the electric properties of the commercial solar panels as well as the electric circuits made by the discrete devices on the circuit board was visualized.
