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 panel having a first plurality of cells of a first type interconnected in series or in series/in parallel. The method includes: determining an operating voltage of the panel(s); producing additional panel module(s) having a second plurality of thin-film cells of a second type and having a different band gap width than the cells of the panel(s), the additional module(s) being configured to supply an operating voltage equal, within ±10%, to the voltage of the panel(s); positioning the additional module to overlap on or under the panel or one of the panel(s), the module being connected in parallel to the panel(s), or positioning several additional modules to overlap on or under several panels, the several modules being connected in parallel to panels.
