    • PURPOSE: A maximum power point tracking apparatus, a photovoltaic power generating system including the same and a maximum power point tracking method of the same are provided to search a maximum power point of a solar cell module again when a user wants, thereby improving the efficiency of power outputted from the solar cell module. CONSTITUTION: A maximum power point searching signal of a solar cell module is received (S10). A voltage value and a current value corresponding to a present maximum power point of the solar cell module and a first output power value are stored (S20). Multiple second output power values are calculated by scanning the voltage value about all areas of the solar cell module according to the maximum power point searching signal (S30). The first output power value and the multiple second output power values are compared (S40). As a comparison result, the highest output power value is outputted as a maximum power point of the solar cell module (S50).
