Patent ID: 11973073

Abstract:
A photovoltaic device includes 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, and 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 is connected to the first group of photovoltaic cells, and a second power electronics unit is connected to the second group of photovoltaic cells. The second power electronics unit is separate from and not communicating with the first power electronics unit. A control device is operable to vary a first property of the first power electronics unit to vary the first current and the first voltage and 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.
