Radiated electric field from a solar cell module set on the ground plane has been studied experimentally and theoretically in order to clarify the antenna effect of the solar cell module. In experimental examination, the radiated electric field characteristics of the thin-film Si solar cell module were measured by using the semi-anechoic chamber including the ground plane. In theoretical examination, the solar cell was assumed as a conducting wire, which has limited electric conductivity. And the radiated electric field of a solar cell was analyzed by using the method of moment. In both examinations, the maximum value of electric field strength for every frequency was measured or calculated when the solar cell module was rotated by 360 degree. Consequently the calculation value agreed with the measurement one within 3dB at the whole frequency region from 30MHz to 300MHz. As the results, we confirmed the availability and the validity of the calculation method by assuming the solar cell module as the conducting wire in the semi-anechoic chamber with the ground plane.
