  1. Solar Powered Pumping for Irrigation in St. Kitts Charles DauphineeHiltz TannerMichael CooksonStephen CooksonMechanical Engineering Department Dalhousie University

  2. SolaVive Team Design Group: Charles Dauphinee Hiltz Tanner Michael Cookson Stephen CooksonSupervisors: Dr. Peter Allen Department of Mechanical Engineering Dr. Jack Burney Department of Biological EngineeringClient: Dr. Vincent Audain Honorary Consul of St. Kitts Department of Medicine

  3. Design Problem Irrigation • 2 Acres of fertile soil (sandy loam) • Horticultural Crop • Requiring: 35mm/week • Existing tank : 85ft x 1000ft from 117358USG reservoir • Social cost of present solution

  4. Mission • Solar powered machinery is ideal for agriculture in developing countries • Rural communities far from power grids • Solar flux availability • Need for ecologically sustainable technologies • Design Criteria • simple assembly / maintenance • ruggedness • transportability • efficiency

  5. Impact on St. Kitts • Expands minimal existing irrigation • Lengthens growing season • Creates year-round employment • Lowers price of produce • Crop export possibilities • Solar versus gas and grid

  6. Integrated System • Subsurface Drip Irrigation • 4500 Gallon Water Storage Tank • P-D Dankoff Solar Pumps • Linear Current Booster • 1.44 kW Photovoltaic Array • Existing Open Reservoir

  7. Component Choices Irrigation • Subsurface Drip Irrigation • Distribution efficiency Pump-Motor • P-D Sliding Vane Pumps in parallel • 15.8 USgpm @ 113 ft • 12 volt PM DC motor • high efficiency at integral hp

  8. Component Choices Photovoltaics • Architecture for Reliability • LCB for Maximum Power • RETScreen Analysis: 1.7kW

  9. Installation & Maintenance • Installation Manual • Connecting PV Modules • Pump inlet/outlet setup • Maintenance Manual • General Maintenance • Preventative Maintenance • Troubleshooting • PV array • Pump & Motor • Irrigation System

  10. Numerical Analysis • Cybernet Simulations • Create nodes on irrigation CAD drawing • Pressures in junctions, pipes, valves • As a tool for: • Design • Change diameter of tubing, Height of reservoir • Testing • Numerical Model

  11. Sponsorship & Assembly • Project Cost: $32K • Testing Methods • Scaled Model • Numerical Analysis • System Assembly • Challenges • Reynolds No • Modularity: Fittings, Wires, Valves

  12. Testing • Day 1 • Partially Cloudy • Not enough pressure head • Expected flux, delivery • Actual flux, delivery • Efficiencies

  13. Testing • Day 2 • Sunny and appropriate head • Expected flux, delivery • Actual flux, delivery • Efficiencies

  14. Interpreting Results • Efficiencies Predicted Actual Average

  15. Testing Conclusions • Importance of proper component sizing • Supply chain management • Data acquisition system • Modularity is key • Intuitive understanding

  16. Future of SolaVive • More Testing • Implementation • Engineers in Development • Other Alternative Energy Projects
