Method of Controlling Flying Object, Flying Object, and Computer Program

A method of controlling a flying object including a generator , which includes solar cells, and an energy storage apparatus is configured such in a case where, during flying of the flying object , a voltage of an energy storage device in the energy storage apparatus reaches a lower limit voltage of a voltage range in which charge and discharge of electricity can be reversibly repeated, the flying object is made to keep flying and/or descend while making the energy storage device discharge electricity within a voltage range lower than the lower limit voltage.
