1. A light collecting device comprising:
a light collecting member that collects sunlight and performs irradiation of the sunlight;
a drive device that drives the light collecting member; and
a control device that controls the drive device, wherein:
the light collecting device irradiates a parked vehicle equipped with a solar power generation device provided with at least one solar cell panel with light using the light collecting member;
the drive device is able to change an inclination angle of the light collecting member with respect to a horizontal plane;
the control device sets a target inclination angle of the light collecting member with respect to the horizontal plane to adjust a power generation efficiency of solar power generation by the solar power generation device to be equal to or higher than initial power generation efficiency that is the power generation efficiency at an initial position of the light collecting member, based on a position of the solar cell panel and an altitude and an orientation of the sun; and
the control device controls the drive device such that the inclination angle of the light collecting member with respect to the horizontal plane becomes the target inclination angle.
