Abstract
A solar cell testing apparatus is provided that tests bypass diodes in a solar cell string constructed by connecting a plurality of solar cell modules, which include solar cells and the bypass diodes, in series for failures in the open position. The solar cell testing apparatus includes a unidirectional element that is connected between a positive electrode and a negative electrode of the solar cell string, and a voltage applier that applies a test voltage across the positive electrode and the negative electrode of the solar cell string to which the unidirectional element is connected. The solar cell testing apparatus also includes a current detector that detects a current flowing in the solar cell string, and a processor that executes processes that measure a current value of a shorted current of a solar cell string and tests for failures.
