1. A solar charging system configured to be mounted on a vehicle, the solar charging system comprising:
a power generation module including a solar panel;
an auxiliary system including an auxiliary battery that stores power generated by the power generation module, and an auxiliary load to which power is supplied from the auxiliary battery;
a high-voltage battery used for driving the vehicle; and
a control unit that is provided between the high-voltage battery and the auxiliary system and that controls power transfer between the high-voltage battery and the auxiliary system, wherein the control unit is configured to
supply power of the high-voltage battery to the auxiliary system in a case where power transfer from the high-voltage battery to the auxiliary system is requested and in a case where the power generated by the power generation module is not being supplied to the auxiliary system, and
supply the power of the high-voltage battery to the auxiliary system in a case where the auxiliary battery is in a predetermined state, even in a case where the power generated by the power generation module is being supplied to the auxiliary system, wherein the predetermined state is a state in which a power storage amount of the auxiliary battery decreases at a predetermined speed.
