Abstract
A vehicle-mounted solar power generation device includes a solar panel, a solar battery that is a battery temporarily storing electric power, and a controller configured to perform control by switching between an electric power generation mode in which the solar battery is charged with a generated electric power of the solar panel and an electric power saving mode in which at least the charging of the solar battery is stopped such that power consumption is suppressed in comparison with the electric power generation mode. The controller determines to switch between modes based on the output voltage of the solar panel. In the electric power saving mode, the controller restricts a switch to the electric power generation mode based on any of the frequency of switching between modes, the amount of electric power stored in the solar battery, and the state of stoppage of a vehicle.
