The system comprises: - several main photovoltaic generators (Gp1-Gpn), - several additional photovoltaic generators (Ga1-Gan), each one made up of several photovoltaic generator blocks (B1-Bn) - several inverters (I1-In) intended to convert direct voltage/current into alternating voltage/current, - several switching means (Sw1) arranged between the outputs of the main generators (Gp1-Gpn) and the inputs of the inverters (I1-In), - several second switching means (Sw2) arranged between the outputs of the generator blocks (B1-Bn) and the outputs of the additional generators (Ga1-Gan), and - several means to automatically control both switching means (Sw1. Sw2) to selectively connect/disconnect the outputs of the main generators (Gp1-Gpn) and of the generator blocks (B1-Bn) to/from the inputs of the inverters (I1-In), The method is provided to carry out said automatic control of the switching means.
