1 Solar Powered Traffic Solutions for Tribal Roadway Safety By Joe Wise President / Minister of Unusual Projects Solar Traffic Controls, L.L.C. Wireless Traffic Control Solutions

2 Why Use Solar Power? No Need for AC Connection to Equipment Minimizes Installation and Life Cycle Costs Self-contained System Independent of the Power Grid Minimizes Installation Time Little or No Maintenance for Years

3 Typical Applications School Zone Beacons 24-hr Hazard Beacon High Water Warning Pedestrian Crossings In Roadway Lighting Radar Speed Signs Railway Warnings LED Enhanced Signs LED Lighting

4 Fundamental Components of a Solar Power System Solar Array Charge/Load Controller Battery Bank Wiring Wiring Load There are 5 basic building blocks of a solar power system: Solar Array Charge Controller The Load Battery Wiring

5 Specifying a Solar Power System Proper Project Specifications Assure Correct Design and System Success Know Your Location (Sunlight Levels) Know Your Load (Amps Drawn) Know Your Projected Duty Cycle (Average Run Time/Day)

6 Think of Solar Like a Bank Account Solar array output = Income Stream Battery reserve = Savings Load draw = Expenses Balance income and savings with expenses or else! Solar Array (Income) Battery Bank (Savings) Load x Duty Cycle (Expenses)

7 Load Tabulation How Much Power Do You Need? Size, Brand and Color of Lamps System Controls Radar Displays Sensors Modems Radios

8 Location/Geography Affects Latitude Affects Winter Sunlight Level Altitude Impacts Solar Radiation Levels Geographic Factors Such As Proximity To Bodies of Water or Mountains Historical Solar Radiation is Available from the DOE Sunlight Levels

9 Duty Cycle-How Long is the Load Consuming Power? Well Defined Hours of Operation Intermittent Use Systems School Zone 24-hour Flasher Radar Sensors Wireless Crosswalk Sensor Activated Systems Radar Speed Displays

10 Vendor Response Sizing Report - Why are you being offered a particular solution? Detailed System Description Component Ratings Projected Performance Throughout the Year

18 Solar Flasher Application- Solar PED-X Wireless Crosswalks Units Located at the Crosswalk Programmable Run Time Single or Dual Beacon FHSS Radio Link Fault Mode Program Vandal Resitant Push Button

19 Solar Flasher Application- Sensor Activated Crosswalk Flashers Flashers Upstream from Crosswalk Programmable Run Time Radio Link with Digital Coding Single or Dual LEDs Pedestrian Detector at Crosswalk

20 Self-Contained High Water Warning Flashers Electronic Sensor with Time Filtering Cellular Dialer Option Radio Connection to Traffic Control Cabinet Radio Link Between Units

21 Distributed High-Water Warning System-Detector Redundant Sensors Radio Link to Slaves Cellular Alarm Card Redundant Alarm Routine Built in Self-Test

22 Distributed High-Water Two-Line VMS Warning System- Dual 12 LED Flashers (1100 Cd) Built in Self-Test Radio Link to Master Pager Activation for Back Up of Radio Flasher/VMS

23 Game Crossing Warning- Passive Single or Dual Lamps Timer Activated Automatic Adjustment for Length of Day with Season

24 Game Crossing Warning- Active Flasher Game Activated Flasher Thermal Imaging Detects Game at Crossing Point Electric Fencing for Channeling Game FHSS Radio Link

25 Game Crossing Warning- Active VMS Game Activated VMS FHSS Radio Link Modified Standard VMS Trailer Operates in Conjunction with Game Flashers

26 Radio Activated Railway Warning Flashers FHSS Industrial Radio Fault Detection Intrusion Alert Dual 12 Lamps Master Radio Tied to Track Monitor

27 In Roadway Lighting Systems LED lamps in fixtures Runway grade fixtures All DC operation Visible in bright sunlight conditions Outlines the crosswalk to enhance pedestrian saftey

28 Fire Station Exit Beacons 12 Amber LEDs Radio Activation Self-contained Confirmation Lamp for Driver Optical, Handheld and Wall Mount Triggers

29 Fire Station Beacons- Activation Options Wall Mount Transmitter (in station) Handheld Transmitter (truck) Optical Detector- Transmitter (driveway)

30 Fire Station to Tractor Crossing Flasher Tractor or Truck Crossing Flasher Radio Remote Activation Sensor Activation

31 LED Enhanced Stop Sign Solar Powered Octagonal Lamp Pattern Field Repairable Fits Standard Square Tubing

32 Solar Powered Area Lighting Self-contained solution Cost effective over AC power Quick to deploy LED solutions improving light levels for solar applications

33 Solar Area Lighting Example Parking lot system Compact fluorescent lamp assemblies Dusk to dawn operation Security level lighting Nassau, Bahamas

34 Solar Powered Sport/Park LED Fixtures Time Of Day Operation Vandal Resistant Push Button Greater Use of Public Facilities Lighting
