1. A method for optimizing an existing generator system based on photovoltaic cells and provided with an existing photovoltaic panel or a group of existing photovoltaic panels, each existing panel being provided with a first plurality P of cells of a first type which are interconnected in series or in series/in parallel, comprising:
determining an operating maximum power point voltage VMPP of said existing panel or group of panels,
producing one or more additional modules comprising a second plurality Q of photovoltaic cells of a second type and having a different band gap width than the cells of the existing panel or of the existing panels of the group of existing panels, said second plurality Q of cells of the additional module(s) being configured to supply an operating voltage V1 equal, to within ±10%, to said maximum power point voltage VMPP of said existing panel or of said group of existing panels once assembled with said one or more additional modules,
positioning said one or more additional modules in an overlapping manner on or under the existing panel, said one or more additional modules being connected in parallel to said existing panel, or positioning said one or more additional modules in an overlapping manner on or under several of said existing panels of said group of existing panels, said one or more additional modules being connected in parallel to at least some of the existing panels or said group of existing panels.
