Photovoltaic module and photovoltaic system including the same

A photovoltaic system comprising:

• a plurality of photovoltaic modules to output AC power to a grid;
• and
• a gateway to perform data communication with the plurality of photovoltaic modules,
• wherein each photovoltaic module comprises:
• a solar cell module including a plurality of solar cells;
• a junction box to convert DC power from the solar cell module to AC power;
• a first cable through which the AC power from the junction box is output to an outside;
• and
• a second cable connected to a controller in the junction box for output or input of communication data.
