  • 2. Solar Electric Systems in Water Pumping Copyright © Naps Systems Oy 2012 • Pumping water from wells, boreholes, rivers or lakes in remote areas • Water used for domestic, health care or irrigation • Main system components: solar electric array, AC inverter and a submersible pump/motor unit • Pumps can operate with 15-100m head giving about 17-40m3 water a day • No need for batteries: water stored in reservoir tank • Number of system elements depends on the pumping head, required amount of water and the solar irradiation available at site
  • 3. Case: Project in Yemen Objectives and site specific issues Copyright © Naps Systems Oy 2012 Objectives: • To pump clean water for domestic and health care use • To provide power for water pumping system Site specific issues: • High mountain area with no electricity grid • Extension of the electricity grid would have been expensive because loads are relatively small (1200 W) • Due to difficult terrain regular fuel supplies would have been difficult. In addition maintenance of the mechanical equipment problematic
  • 4. Water Pumping Project in Yemen Implementation Copyright © Naps Systems Oy 2012 System configuration: • 24 Naps 50G modules, total power (1200 W) • A 1500 Watt inverter • Pump SP1A-28 • Cables and structure for installation Output: • 8000 - 9000 litres of water per day Cost comparison: • Solar electricity 0,54 USD per m3 • Diesel 0,63 USD per m3
  • 5. Water Pumping Project in Yemen Conclusions Copyright © Naps Systems Oy 2012 • Solar electricity is technically and economically successful • Implementation was smooth, only little site preparation was needed • System meets the needs of the community • Further sites for electric systems is being planned • Solar electric pumping is competitive for villages of max. 2000 people
