Abstract
Discussed are a photovoltaic module and a photovoltaic system including the same. According to an embodiment, the photovoltaic module includes a solar cell module including a plurality of solar cells, and a junction box attached to a back surface of the solar cell module, wherein the junction box includes a capacitor unit to store a direct current (DC) power from the solar cell module, and a shutdown unit disposed at a front end of the capacitor unit and to operate to consume the DC power stored in the capacitor unit and temporarily interrupt power output of the solar cell module when the DC power from the solar cell module is outside of a permissible range. Thus, when DC power outside of the permissible range is supplied, the power output can be quickly interrupted while the DC power stored in the capacitor is consumed.
