The method (M) for the research of maximum available power in photovoltaic generators comprises: a step (1) of splitting up the total possible output voltage values (V) of a photovoltaic generator into a predetermined number (N) of voltage ranges (V 0 -V 1 ,...,V N-1 -V N ); a step (2) of assigning each of the voltage ranges (V 0 -V 1 ...V N-1 -V N ) respective priority values (x i ; a step (3) of selecting a possible point of maximum absolute power (V MPP ) of the photovoltaic generator. The method (M) also comprises repeating cyclically: a step (4) of selecting one of the voltage ranges (V 0 -V 1 ...,V N-1 -V N ) according to the priority values (x i ); a step (5) of selecting one point of comparison (V c ) within the selected voltage range; a step (6) of comparing the power value read in correspondence to the point of comparison (V c ) with the power value read in correspondence to the possible point of maximum absolute power (V MPP ); if the power value in the point of comparison (V c ) is higher than the power value in the possible point of maximum absolute power (V MPP ), a step (7) of setting the point of comparison (V c ) as new possible point of maximum absolute power (V MPP ), a step (8) of increasing the priority value (x m ) of the selected voltage range and/or a step (9) of decreasing the priority value (x j ) of at least one of the non-selected voltage ranges.
