There is provided a solar battery control apparatus comprising: a solar battery in a vehicle; a vehicle speed detecting unit; a load circuit capable of be controlled to vary a generated current; and a control unit configured to perform MPPT control while controlling the load circuit to vary the generated current, wherein the control unit varies the generated current within a range having a certain upper limit value upon the speed of the vehicle being detected to be greater than a predetermined speed. The predetermined speed is set to be less than a speed at which the generated current becomes unable to be varied to correspond to a change in an i-V output characteristic of the solar battery, and the certain upper limit value is set to be less than a value of short-circuiting current having been reduced according to the change.
