A method for determining the absolute point of maximum power delivered by a string (1) of photovoltaic panels (100) connected together in series. The method foresees that the sequence of operations (A) be carried out cyclically for every time interval ΔΤ2, repeated a maximum number of times M, which foresees that the voltage value Vi set for the string (1) be decreased by a voltage quantity ΔV2 of value substantially equal to the open circuit nominal voltage value of each of said photovoltaic panels (100) belonging to said string (1), observing the value of the power delivered Pvi - ΔV2 at the voltage value Vi - ΔV2, and, in the case in which the power value PVi - ΔV2 is greater than the value of the power PVi delivered at the set voltage value Vi, setting as voltage value Vi on the string (1) of photovoltaic panels (100) the voltage value Vi decreased by the quantity ΔV2. |
