Abstract: The present invention relates to a photovoltaic module. A photovoltaic module according to an embodiment of the present invention comprises a solar cell module, a micro-inverter to convert DC power generated by the solar cell module into AC power, a controller to control the micro-inverter's operation, and an interface unit connected to power grid supplying external electrical power and to provide the AC power to the power grid, the controller to control operation of the micro-inverter such that the AC power is matched to the external electrical power flowing into the power grid. The photovoltaic module according to the present invention can provide electrical power generated at solar cell modules through a simple connection to power grid which supplies electrical power to home, reducing consumption of electrical power flowing into home.
