Zusammenfassung:In the disclosure, the occurrence of an arc is rapidly detected while the frequency of erroneous detection is suppressed. An arc detecting apparatus includes an arc presence/absence determining part determining presence or absence of an arc based on an AC current from a solar cell, and a repeat number setting part setting, based on the DC current from the solar cell, a repeat number of processing that the arc presence/absence determining part repeatedly performs to determine the presence or absence of the arc.
