An integrated photovoltaic panel has one or more integral DC-DC converter circuits. The DC-DC converter input port couples to a section of at least one photovoltaic (PV) device of the panel separate from PV devices feeding other converters. The converter has an MPPT controller for operating the converter to transfer maximum power from coupled photovoltaic devices to its output port. The PV panel has a transparent substrate to which PV devices are mounted. A laminating material seals PV devices and converters to the substrate. In embodiments, the panel has multiple converters connected with output ports in series. The integrated PV panel provides summed maximum powers of each section of PV devices. In some embodiments the DC-DC converters are complete with inductors, in other embodiments a common inductor is shared by multiple converters of the panel, in a particular embodiment the common inductor is parasitic inductance of the panel. |
