Abstract

The present invention is a control device for a solar battery which is capable of setting search points for which power loss accompanying variation in amount of solar radiation is reduced more. A power conditioner (2) has: a current sensor (11) which detects an output current of a solar battery; an extreme value monitoring unit (6) which, with a current value obtained from the current sensor (11) as input, assesses whether or not an operating power value of the solar battery is an extreme value, and on the basis of the assessment result, stores a voltage value and a current value which have been assessed to be extreme values; and a fluctuation determination unit (17a) which, on the basis of the ratio of the current value obtained from the current sensor (11) to an output current value of the solar battery when assessed to be an extreme value, sets a voltage width when performing an extreme value search of voltage- power characteristics of the solar battery.
