Abstract
A method and device are provided for operating an energy installation and include multiple photovoltaic modules linked to at least one inverter. Switching means are provided to electrically arrange the photovoltaic modules in at least two configurable series of photovoltaic modules parallel to each other, so that each module can be individually connected to or disconnected from any of the series of photovoltaic modules. Current values and voltage values supplied individually by each photovoltaic module are measured. Intermediate electrical magnitudes are calculated or chosen corresponding respectively to a plurality of configurations of the series of photovoltaic modules. The intermediate electrical magnitudes are compared with each other or with a reference magnitude. A configuration is selected of each series of photovoltaic modules according to the result of the comparison.
