A photovoltaic unit is disclosed comprising a plurality of sub-units connected in series, each sub-unit having a main input and a main output, which main output is connected to the respective main input of a neighbouring sub-unit, each sub-unit further comprising a segment comprising one or more series-connected solar cells, and a supplementary power unit, wherein the supplementary power unit is configured to at least one of receive power from or supply power to the neighbouring sub-unit. The supplementary power unit is preferably a DC-DC converter, and arranged to exchange energy between neighbouring segments, without requiring a high-voltage connection across the complete string (of more than 2 segments). The converter may be inductive or capacitive. A DC-DC converter configured for use in such a unit is also disclosed, as is a method of controlling such a photovoltaic unit.
