Maximum power point tracking control apparatus for a solar battery includes: a voltage detection section for detecting an output voltage of the battery; a current detection section for detecting an output current of the battery; a storage section storing therein duty cycle values of a solar-battery output controlling switching element that are predefined on the basis of relationship between output voltages and currents of the battery; and a control section for, at the start of maximum power point tracking control, reading out, from the storage section, one of the duty cycle values that corresponds to the detected output voltage and controlling a duty cycle of the switching element in accordance with the read-out duty cycle value.
