1. SOLAR POWER SYSTEM FOR EXPERIMENTAL
UNMANNED AERIAL VEHICLE (UAV) DESIGN AND
FABRICATION
Nowadays, one of the most challenging problems of the world is the limitation of the
source of energies. One way to overcome this problem is to looking for another source of energy.
Solar power is one of them. In these days, using from solar cells has become conventional. In
one aspect, they are used in Unmanned Aerial Vehicles (UAV). Conventionally, Unmanned
aerial vehicles are aircrafts either using remote control or automatic control for their guidance.
These aircrafts are used for carrying devices as a payload such as a camera, sensors, and
communication devices. In recent years, the interest to development of such aircrafts with variety
missions has been increased. The solar cells are used as an unlimited source of power for motor
and other electrical subsystems.
Existing System:
The most challenging problem in an Unmanned Aerial Vehicle (UAV) refers to its source
of power. Since battery and fuel are two common sources of power for UAVs, the endurance of
such aircrafts is restricted. Using other sources of power can be useful to increase the endurance
of the aircrafts. Unmanned solar aircrafts are considered as a group of UAVs in which, solar cells
are used as a source of power.
Proposed System:
A Solar Power System for experimental unmanned aerial vehicle (UAV) is designed and
represented in this paper; solar cells are used to increase the endurance of the aircraft. A
microcontroller-based controller was developed to collect the output power data of power source
to be sent. Since solar cells were decided to be installed, upper surface of which is smooth
enough for putting solar cells without bending them, should be selected. The RF wireless
technology is used to control the experimental unmanned aerial vehicle from remote area by
using wireless command.
