Title:
PHOTOVOLTAIC MODULE AND PHOTOVOLTAIC SYSTEM PROVIDED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2017/191986
Kind Code:
A1
Abstract:
The present invention relates to a photovoltaic module and a photovoltaic system provided with same. The photovoltaic module according to an embodiment of the present invention comprises: a solar cell module provided with a plurality of solar cells; a converter unit for level-shifting direct current power from the solar cell module; an inverter unit for outputting alternating current power by converting the direct current power from the converter unit; a power factor regulating unit comprising a plurality of passive elements and regulating, on the basis of at least some of the plurality of passive elements, the phase difference between an alternating current voltage and an alternating current outputted from the inverter unit; and a control unit for controlling the power factor regulating unit on the basis of a power factor regulation signal. Accordingly, the power factor of the alternating current power outputted from the photovoltaic module can be regulated in a simple manner.
