  1. Solar Powered Air PurifiersUNEEC Final Presentation Kevin Black Brian Chung Evan Lindell Michelle Marval

  2. Origin and Motivation • Many impoverished nations – Solar power can help • Example – Webuye, Kenya • Citizens need clean air, solution is in solar power.

  3. Projected Impact • Currently: Air pollution from Pan African Paper Mill • Our project will bring: • Cleaner air • Improved quality of life

  4. Scientific Basis • Radiancy value = 5.25 kWh/m2 per day • Fill Factor = ImaxVmax/ IscVoc • Photovoltaics

  5. Key Parts of Experiment • Power going into battery • Power going out of battery • Current-Voltage relationship of solar panel Solar cart manual

  6. Solar Cell Efficiency • Efficiency = Maximum Power/Optical Power*Area • Theoretical Efficiency = Fill Factor • Fill Factor = 69.01% • Efficiency = 21.10% www.solarnavigato.net

  7. Battery Efficiency • Battery efficiency = Output Power/Input Power • Input Power = 448.803 • Output Power = 163.575 • Efficiency = 36.45%

  8. Storage Efficiency • Storage efficiency = actual yield * theoretical yield * battery efficiency • Storage efficiency = 5.31%

  9. Significance of Findings • Silicon solar panels are not efficient but do produce useful amounts of power • NiMH batteries are not efficient • Project done on a cloudy day-some data skewed

  10. Site Selection • Webuye, Kenya • Has a large solar flux • Kenya standard of living ranked 143 of 177 countries on the Human Developmental Index www.gcmonitor.com

  11. Social and Political Constraints • Social Constraints: • Education of citizens • Political Constraints: • Government support for Pan African Paper Mill • No sense of responsibility to the citizens

  12. Justification • Paper mill spews out H2S • Harmful to citizens • Poor ventilation in homes • H2S gets trapped in homes • Solar Energy can provide energy for better ventilation www.gcmonitor.com

  13. Design Components • Solar Panel • Motorized Fan • HEPA Filter • Lithium Polymer Battery • Additional Infrastructure

  14. Power Needed for Device • Device schematic circuit: • Operates on 10 Watts of power • Solar panel can produce 10 watts of power

  15. Pricing of Batteries • Lithium Polymer Batteries • Improved current and voltage output • Price for one battery = $16.57 http://www.thomas-distributing.com/ipower-9v-lithium-rechargeable-battery.php

  16. Cost Analysis

  17. Cost of Delivery

  18. Economic Impact • The device will allow people to breathe better in their homes • This leads to better work performance and therefore more production www.kardias.com

  19. Maintenance Cost • $125,000 for maintenance over 5 years • Primarily the cost of airfare for medical professionals and engineers to do annual studies. • After this technology is proven, maintenance drops to price of replacement filters and batteries. • Maintenance is small in comparison to the benefit of allowing people to breathe cleaner air

  20. Impact on Quality of Life • Quality of life will be improved • Better air to breathe fewer respiratory problems • Ancillary Effects: • More oxygen leads to improved learning • Fewer missed school/work days • Better air leads to better productivity in the workplace

  21. Conclusion • H2S levels in Webuye are 140 times amount allowed by World Health Organization • The UN can help by funding our SPAP • The cost is $312,844.00 which is low compared to its benefits!
