An UAV is defined as an unmanned aerial vehicle that can fly autonomously or remotely, that is with the use of controller. An automated UAV has increased the efficiency by eliminating the use of a drone operator. But, the limited endurance limit of such conventional drones has remained to be major issue. Also, in order to increase the endurance limit of unmanned aerial vehicles, solar-powered UAVs have been developed. These, solar-powered UAVs use photovoltaic panels to absorb sun’s energy and convert it to electrical energy. Also, such Solar-powered UAVs are extensively used in militaries, paramilitary forces, and other national security agencies and also includes a number of market applications.
