UCF Solar Farm:Photovoltaic Array – Monitoring System
Solar Farm - Project Overview
• Design a panel by panel monitoring system– Monitoring system must be self sustaining– Wirelessly transmit data– Data will be collected every 5 minutes for duration
of the day
• Publish real time information online – Data must be graphed for easy interpretation– Publically accessible
Solar Farm - Solar Panels
• 11 Solar panels used – Sharp Nu-U240f1– 240 Watts– 37.4 Volts– 8.65 Amps– Weight: 44.1lbs/ 20.0 kg
• These panels will be connected in a series circuit with one another• Locally distributed
64.5 inches
39 inches
Solar Farm - Design Goals & Objectives
• Monitor each panel for:– Voltage– Temp– Current
• Display data online in real time• Transmit data from field to web server
wirelessly
Solar Farm - Primary Circuit Board
• This board will handle power to the whole system for all components
• Change channels on the Multiplexers that were implemented
• Handle all wireless communication

Solar Farm - Multiplexer
• A multiplexer or MUX is a device that combines several electrical signals into a single signal. There are different types of multiplexers for analog and digital circuits.
• Programming the MUX gives desired values.

Solar Farm - Wireless Technology
• XBee PRO 802.15.4– Range - Indoor Range 300 ft.
- Outdoor Range 1 mile– No monthly fee
• Low complexity.• Perfect for low-data transfer.• Very low power requirement.• Two modules, transmitter and receiver.

Why Photovoltaics at UCF?
• Energy from the sun is renewable
• Power guaranteed for 25 yrs
• Clean, environmentally friendly, and silent
• On-site energy production
• Capacity is available on campus
• President John Hitt engaged UCF in the President’s Climate Commitment

Solar Farm Project Goals
• Conduct a feasibility study of constructing a 3-MW solar farm on the UCF main campus
• 3 MW will supply approximately 15% of the peak energy demand on the main campus (Norvell, 2010)
• Project involves constructing design prototype– Multidiscipline senior design team
(MEs, EEs, and IEs)
Prototype Design• Sharp NU-U240F1
(240 W) Solar Panel– Selection driven by low
shipping costs from local distributor
• Fixed mounting system – Minimal maintenance
• Supports 11 solar panels• Individual panel monitoring
– Allows for immediate control of system malfunctions
Forecast AnalysisPrototype Benefits2
• Take 0.548 vehicles off the road• Eliminate CO2 emissions from 0.339 homes
• Eliminate CO2 emissions from 117 propane cylinders used for home barbeques
• Save UCF $283.30/year
Each year, the prototype (0.003 MW) can:

Forecast AnalysisTransitioning from 0.003-MW Design to 3-MW Design
• Panel requirements: 11 panels to 12,507 panels– This requires 1,137 arrays– Space is necessary between rows
• Land requirements: 240 sq ft to 653,400 sq ft– 0.006 acres to 15 acres– More than 11 football fields
Forecast Analysis3-MW Design Benefits3
• Greenhouse gas emissions from approximately 623 vehicles
• CO2 emissions from the electricity use of 386 homes
• CO2 emissions from 132,487 propane cylinders used for home barbeques
• $322,110/year from UCF energy bill
