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!

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

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 , 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 RelayFigure 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
