•Electrical Engineering Major
specializing in Power Systems
•Electrical Engineering Major
specializing in Power Systems
•Confronts all energy related
problems
•Team Leader
•Electrical Technician experience
•Experience in assembly of
Mechanical equipment
• Original project from an innovative
ideas – improvement/different
approach to existing design
• Research, design, and
implementation throughout two
semesters (or one, depending on
major)
• Working in teams and managing
time properly are the key
• Platform for new inventions and
excellent way to showcase the
leadership and technical qualities
of the FIU student population
• Development of an Energy Management System
• Two sources: solar and utility
• Multiple loads: motors, and lighting
• Renewable source will be used when utility rates are high
• Goal is to reduce electricity costs without disturbing the loads
• Vital aspects of our Senior Design Project:
–
–
–
–
Multidisciplinary collaboration and successful teamwork
Developing a plan of action
Detailed research of the topic
Work with anticipation!
• A photovoltaic system is a system which uses one
or more solar panels to convert sunlight into
electricity.
• It consist of multiple components, including:
- PV modules
- Mechanical and electrical connections
- Mountings
- Means of regulating and/or modifying
the electrical output.

1. Monocrystalline
• Cells cut from a single crystal of silicon
• They are a slice of crystal indeed
• In appearance, it will have a smooth
texture and you will be able to see the
thickness of the slice.
• Most efficient and the most expensive
to produce.
• Rigid and must be mounted in a rigid
frame to protect them.
2. Policrystalline
• Cells are effectively a slice cut from
a block of silicon
• Large number of crystals
• Speckled reflective appearance
• Less efficient and less expensive
than monocrystalline cells
• Rigid frame needed
3. Amorphous cells
• They are assembled by placing a thin film of
amorphous (non crystalline) silicon onto a
wide choice of surfaces
• Least efficient / least expensive
• Flexible
• Power output reduces over time, particularly
during the first few months, after which time
they are basically stable
• The quoted output of an amorphous panel
should be that produced after this
stabilization

in Germany
Figure 3 – Old house
renewed with solar panels
• Is an open-source single-board
microcontroller
• Easily implemented in various
multidisciplinary projects
• Programmed using language
similar to C++
• Detailed explanations are
provided for each exercise
• Vital to understand the operation
of a microcontroller and how it
can operate certain components!
Figure 4 – Size of Arduino Board
• Two sources will be used –
solar panel and battery
• Microcontroller will switch
from one to another
depending on which is
generating higher voltage
• Relay will perform
switching operation
Figure 5 – Circuit assembly
1. analogRead()
•
•
The analogRead() method reads the value of an
analog input pin.
Possible values range is 0-1023, where 0 is 0 volts
and 1023 is 5 volts.
2. if (conditional) and ==, !=, <, >
(comparison operators)
• if, which is used in conjunction with a comparison
operator, tests whether a certain condition has been
reached, such as an input being above a certain number.
The format for an if test is:
• Is an electrically operated switch
• Used to control different loads or sources with a single
circuit
• Various types – DPDT to be used in this sample exercise
Figure 6 – DPDT Relay
Figure 7 – Wiring Diagram of DPDT
• SD project – final step in the pursue of your degree
• Teamwork, organization, and communication are key!
• PV Systems are growing throughout the industry
• Monocristallyne, policristallyne, and amorphous panels
• Sample assignment includes Microcontrollers,
Transistors, and Motors – some of the most frequently
used components in a Senior Design Project
