Abstract: A photovoltaic system or installation, for generating electricity, which includes auxiliary charging modules for each solar tracker of the photovoltaic system to charge or supply energy to an auxiliary power supply device such as a battery, in order to power the photovoltaic system during the initial stages of the set-up process of the electric energy generation plant or during incidences in the normal operation of the photovoltaic system or installation. In addition to the auxiliary charging modules, the photovoltaic system comprises: one or more solar trackers, wherein each solar tracker comprises a plurality of photovoltaic panels, a DC/AC inverter to transform the DC electricity generated into AC electricity which is then supplied to an electric grid or an electric power distribution system, and a solar tracker controller, for each solar tracker, which controls several aspects of the one or more solar trackers of the photovoltaic system.

Abstract: The installation comprises: a DC-generating arrangement formed by electrical generators (PV1 . . . PVn) which are connected in series and located inside a local area, and supply a remote area with a total direct current that is the sum of the current generated by each of the electrical generators (PV1 . . . PVn); and an auxiliary power supply device (D) which is arranged inside the local area and provides the auxiliary system (E) with a supply voltage in the local area, wherein the auxiliary power supply device (D) is made up of a current-fed power converter (CP) electrically connected in series, respective input terminals (T1, T2), in the DC-generating arrangement between two connection points (p1, p2) of the electrical generators, located inside the local area.
