摘要
The solar cell module diagnosis method measures the frequency characteristic including the resonance point of impedance between the two poles of the solar cell module and the frequency characteristic including the resonance point of impedance between the output cable and the frame, and the equivalent circuit of the solar cell module. An analysis step for determining the constant, and a determination step for comparing the equivalent circuit constant determined in the analysis step with the equivalent circuit constant acquired in advance to determine a change in the state of the solar cell module.
