Photovoltaic module and photovoltaic system comprising the same

Abstract

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.
