摘要： A solar cell testing apparatus tests bypass diodes in a solar cell string, which is constructed of solar cell modules including solar cells and the bypass diodes, for open-position failures and includes: a unidirectional element connected between positive and negative electrodes of the solar cell string so as to permit passage of the current outputted when the solar cells generate power; a voltage applier that applies a test voltage, which exceeds a sum of forward direction voltages of the bypass diodes and sets the negative electrode potential higher than the positive electrode potential, across the positive and negative electrodes; a current detector that detects a current flowing in the solar cell string; and a processor that tests for open-position failures by comparing currents detected before and after application of the test voltage with the unidirectional element connected between the electrodes of the solar cell string.
