    摘要： A photovoltaic module and a photovoltaic system including the same are disclosed. The photovoltaic module includes a solar cell module, a converter unit to convert levels of direct current (DC) power from the solar cell module, an inverter unit to convert the DC power into alternating current (AC) power, a cable electrically connected to the inverter unit and to output the AC power to an outside, a communication unit to exchange data with another photovoltaic module, and a controller to control outputting of at least one of phase information and amplitude information of the photovoltaic module for adjusting at least one of a phase and an amplitude of the another photovoltaic module, when the photovoltaic module is set as a master. Consequently, the phase and/or the amplitude of AC power output from another photovoltaic module may be adjusted to be equal.

    摘要： 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.
