1. A vehicle-mounted power source apparatus that charges a battery with electrical power obtained by solar power generation, the apparatus comprising:
a low voltage battery;
a high voltage battery that stores electrical power having a voltage higher than the low voltage battery;
a solar panel that converts sunlight into electrical power;
a buck-boost section that boosts or steps down the voltage of the electrical power obtained through the conversion by the solar panel;
a boost section that boosts the voltage of the electrical power boosted or stepped down by the buck-boost section; and
a control section that charges the low voltage battery with the electrical power boosted or stepped down by the buck-boost section, and that performs switching so as to charge the high voltage battery with the electrical power boosted by the boost section when the amount of electrical power stored in the low voltage battery is equal to or greater than a predetermined value.
