  1. Drinking Water Supply System using Solar Power RenataBakousseva Hessa Darwish Hall Sun

  2. Table of Contents • Introduction • Energy Alternatives • Concentrated Solar Power (CSP) • Wind Power • Solar Power System Design • Hydraulic System Design • Financials • Future Considerations

  3. Introduction • 884 million people in the world live without access to clean water • 1.2 million children die each year as a result of water related diseases such as diarrhea, malaria, and trachoma

  4. The Two Systems • Apatut, the Philippines • 150 households • ~750 inhabitants • 300 mi. north of Manila

  5. The Two Systems • Las Delicias, El Salvador • 470 households • ~3,000 inhabitants • 25 mi. from San Salvador

  6. Problem Identification Provide sustainable, affordable, reliable power source

  7. Energy Alternatives

  8. Power Tower The mirror reflects solar power onto a collector within the power tower. The power tower then sends the molten fluid through the Rankine cycle which generates electricity

  9. Parabolic Trough • Sunlight hits the collectors which reflect the heat onto the absorber tubes • The transfer fluid collects the heat and transfers it to a Rankinesystem

  10. Solar Dish Engine • The sunlight rays collect on the reflector which focuses the collected heat on the receiver • The receiver then transfers the heat onto the engine, a Stirling heat engine that converts the heat power into mechanical work

  11. Solar Comparisons

  12. Wind Power-Las Delicias

  13. Wind Power-Apatut

  14. Solar Power System Design

  15. Photovoltaic Effect

  16. System Components

  17. Solar Panels • BestSun New Energy Co., Ltd • Monocrystalline Silicon Cells

  18. Batteries

  19. Hydraulic System Design

  20. Pump Requirements

  21. Current design- Las Delicias VFD PV modules 394’

  22. New Design, Las Delicias New tank (20,000 gal) 2 new booster pumps 1 new submersible pump

  23. TDH = Static lift + Static height + Head loss

  24. System - Pump performance curves: Las Delicias, El Salvador; submersible pump BestEfficiencyRange

  25. Pump Summary: Las Delicias, El Salvador

  26. Apatut, the Philippines

  27. Pump Summary: Apatut, the Philippines

  28. Financials

  29. Financial Assumptions • Revenue Assumptions • Productivity Gain • Cost Assumptions • $.69/Watt for panels • $.38/Watt for other/indirect • .3% maintenance costs

  30. Investment and Operation

  31. Financial Results • Philanthropic Project • 20 year life span • Government viewpoint • Discount rate = return on debt = 1.6% • Las Delicias, El Salvador • NPV = $413,000 • IRR = 36% • Apatut, the Philippines • NPV = $78,000 • IRR = 41%

  32. Future Considerations

  33. Rainwater Harvesting

  34. Costs

  35. Conclusion • Photovoltaic power supply • Low maintenance costs • Efficient hydraulic system • Economic benefits of clean water

  36. Thank You! • Professor Leonard A. Fabiano • Professor Sean P. Holleran • Adam A. Brostow • Engineers Without Borders • Consultants

  37. Questions?

  38. Tank Sizing Stresses on a curve Stresses on a rectangle Hoop Stresses, unconstrained and constrained.

  39. Tank Sizing Sizing Based on Maximum Tank Volume, operated from pumps

  40. Pump Scheduling • Extreme Scenarios • Daylight Pumping only (9 hrs) • No batteries • Wasted energy • Continuous pumping (22 hrs) • Maximum storage • Iterative method • Utilize excess from daylight only scenario

  41. Scenario 3, Las Delicias
