The disclosed embodiments and principles provide a way to integrate high-efficiency, low-profile power electronics with localized maximum power point tracking (MPPT) into a rooftop shingle-based photovoltaic power system. DC-DC power converters having a height, or profile, as low as ¼ inch for a 200 W power output, are able to be included in a building-integrated photovoltaic (BIPV) roof shingle. The DC-DC power converters increase the relatively low voltage produced by two rows of series-connected photovoltaic shingles, each including photovoltaic cells, to a high voltage used by a DC-AC inverter. For example, DC-DC power converter increases the voltage produced by two rows of series-connected photovoltaic shingles from several tens of volts to approximately 400 volts. Thus, the DC-DC power converters provide a large voltage step-up using a low profile and with very high efficiency.
