1. A photovoltaic device comprising:
a first group of photovoltaic cells of a first cell type, the first group of photovoltaic cells operable to produce a first current and a first voltage;
a second group of photovoltaic cells of a second cell type that is different than the first cell type, the second group of photovoltaic cells operable to produce a second current and a second voltage;
a first power electronics unit connected to the first group of photovoltaic cells;
a second power electronics unit connected to the second group of photovoltaic cells, the second power electronics unit separate from and not communicating with the first power electronics unit; and
a control device including a first controller operable to vary a first property of the first power electronics unit to vary the first current and the first voltage and a second controller operable to vary a second property of the second power electronics unit to vary the second voltage and the second current independent of the first voltage and the first current and the first controller.
