1. An in-vehicle solar charge control system comprising:
a solar panel mounted on a vehicle;
a solar DC-to-DC converter to which power generated by the solar panel is input;
a first DC-to-DC converter to which output power output by the solar DC-to-DC converter is to be input;
a converter control unit configured to switch the first DC-to-DC converter between a first operating state in which power is output while lowering a voltage when the output power is input, and a first stopped state in which power is not output;
a first battery which is chargeable with power output by the first DC-to-DC converter in the first operating state;
a path switching unit provided in parallel with the first DC-to-DC converter on an electrical circuit that connects the solar DC-to-DC converter and the first battery and through which electricity having the output power flows; and
a switching unit controller configured to switch the path switching unit between a first state in which the output power is supplied to the first battery without being input to the first DC-to-DC converter, and a second state in which the output power is allowed to be input to the first DC-to-DC converter that is switched to the first operating state by the converter control unit.
