1. A photovoltaic system comprising:
an output inverter for connection to a third-party network; and
a plurality of strings, each string including a plurality of modules of tandem photovoltaic cells, each module having a first pair of connectors and a second pair of connectors, the plurality of modules of each string being connected to each other in series by means of their first pair of connectors, each string being connected to the output inverter in parallel to each other by means of connectors of each string among the first pairs of connectors, several modules further being connected in parallel via their second pairs of connectors so as to form a first group, said first group further being coupled, via said second pairs of connectors, upstream of the output inverter, to a second group of a plurality of modules composed of a single module or of a series of modules connected to each other in series by their first pairs of connectors, wherein the first group and the second group each comprise a different number of modules, such that the number of modules forming the first group is chosen to obtain the following relationship:
IT1-T2/IT3-T4=b, where b is the number of modules forming the first group, IT1-T2 is an operating current of the second group of modules via their first pair of connectors and IT3-T4 is an operating current of each module of the first group of modules via their second pair of connectors, and the first group of modules and the second group of modules are directly connected without using a DC/DC converter.
