Abstract: An object of the present invention is to provide an ultraviolet light irradiation system and an ultraviolet light irradiation method which can perceive a state of a region where ultraviolet light is irradiated to output/block the ultraviolet light. An ultraviolet light irradiation system 301 according to the present invention includes an ultraviolet light source unit 11 that produces ultraviolet light, an N (N is a natural number) irradiation unit 13 that irradiates an irradiation target region Ar with the ultraviolet light, a sensor unit 31 that detects whether or not an object that should avoid exposure is present in the irradiation target region Ar, and a blocking unit 30 that stops, in a case where the object that should avoid exposure is present in the irradiation target region Ar, irradiation of the ultraviolet light from the irradiation unit 13 to the irradiation target region Ar.

Abstract: A vehicle control device configured to control supply of electric power generated by a solar panel mounted on a vehicle includes a supply destination setting unit configured to set, based on a condition of the vehicle, a target device that is a destination for the supply of the electric power generated by the solar panel, a target setting unit configured to set, depending on the target device set by the supply destination setting unit, target output electric power to be output from the solar panel to the target device, and a power controller configured to control the electric power to be supplied from the solar panel to the target device based on the target output electric power set by the target setting unit.

Abstract: The solar charging system according to the present embodiment includes a solar panel, a drive battery, an auxiliary system including one or more devices, and a controller that controls where to supply power generated by the solar panel. The controller determines whether the solar panel can generate power, and, upon determining that the solar panel can generate power, supplies the power from the solar panel to the auxiliary system to derive the power generated by the solar panel. Upon detecting a fact that the power generated by the solar panel is equal to or greater than a first power, the controller further supplies the power from the solar panel to the drive battery to charge the drive battery.
