Method for the research of maximum available power in photovoltaic generators, characterized in that it comprises: - a step of splitting up the total possible output voltage values of at least a photovoltaic generator into a predetermined number of voltage ranges (V 0 -V 1,...,V N-1 -V N); - a step of assigning each of said voltage ranges (V 0 -V 1,...,V N-1 -V N) respective priority values (x i); - a step of selecting a possible point of maximum absolute power (V MPP) of said photovoltaic generator; and in that it comprises repeating cyclically: - a step of selecting at least one of said voltage ranges (V 0 -V 1,...,V N-1 -V N) according to said priority values (x i); - a step of selecting at least one point of comparison (V C) within said selected voltage range; - a step of comparing the power value generated by said photovoltaic generator at said point of comparison (V C) with the power value generated by said photovoltaic generator at said possible point of maximum absolute power (V MPP); - if said power value in the point of comparison (V C) is higher than said power value in the possible point of maximum absolute power (V MPP), a step of setting said point of comparison (V C) as new possible point of maximum absolute power (V MPP), a step of increasing the priority value (x m) of said selected voltage range and/or a step of decreasing the priority value (x j) of at least one of the non-selected voltage ranges. - a step of splitting up the total possible output voltage values of at least a photovoltaic generator into a predetermined number of voltage ranges (V 0 -V 1,...,V N-1 -V N); - a step of assigning each of said voltage ranges (V 0 -V 1,...,V N-1 -V N) respective priority values (x i); - a step of selecting a possible point of maximum absolute power (V MPP) of said photovoltaic generator; and in that it comprises repeating cyclically: - a step of selecting at least one of said voltage ranges (V 0 -V 1,...,V N-1 -V N) according to said priority values (x i); - a step of selecting at least one point of comparison (V C) within said selected voltage range; - a step of comparing the power value generated by said photovoltaic generator at said point of comparison (V C) with the power value generated by said photovoltaic generator at said possible point of maximum absolute power (V MPP); - if said power value in the point of comparison (V C) is higher than said power value in the possible point of maximum absolute power (V MPP), a step of setting said point of comparison (V C) as new possible point of maximum absolute power (V MPP), a step of increasing the priority value (x m) of said selected voltage range and/or a step of decreasing the priority value (x j) of at least one of the non-selected voltage ranges. - a step of selecting at least one of said voltage ranges (V 0 -V 1,...,V N-1 -V N) according to said priority values (x i); - a step of selecting at least one point of comparison (V C) within said selected voltage range; - a step of comparing the power value generated by said photovoltaic generator at said point of comparison (V C) with the power value generated by said photovoltaic generator at said possible point of maximum absolute power (V MPP); - if said power value in the point of comparison (V C) is higher than said power value in the possible point of maximum absolute power (V MPP), a step of setting said point of comparison (V C) as new possible point of maximum absolute power (V MPP), a step of increasing the priority value (x m) of said selected voltage range and/or a step of decreasing the priority value (x j) of at least one of the non-selected voltage ranges.
