  1. An Overview of Micro Hydro and Power Production Calculations

  2. Hydro power in USA, Canada and the World

  3. Basically, It’s Solar Power

  4. At the heart of the micro hydro system is a water wheel enclosed within a structure. These wheels can be of many forms. Listed are a few of the major types.

  5. Pelton and Turgo Wheels http://wskn.wellington.net.nz/graphics/suepreservation/2%20C%20%20AB%20Pelton%20Wheel.htm Big and Small 4 “ http://www.solareagle.com/microhydro/turgo.html

  7. These Turbines are turned by water. That turning motion creates energy by causing coils of wire to move relative to magnets. With the high head situations we commonly see in the mountains, pelton wheels and turgo wheels are commonly used. Jets are sprayed into cups of these wheels

  10. Generator Housing

  11. Batteries

  12. Balance of System:Inverters and Charge Controllers

  13. Other Parts

  14. Cool Big Pelton Wheel

  15. Assessments

  16. Power Calculations • Power (watts) = Head (ft) * Flow (GPM) 10 Flow Head 15.9 GPM = 1 L/S 3.28 feet = 1 meter

  17. Turtle Island • Turtle Island at high flow 300 GPM (1/2 of flow is 150 GPM) Head 140 feet (140 ft * 150 GPM)/10= 2100 W • Turtle Island at low flow 150 GPM (1/2 of flow is 75 GPM) Head 140 feet (140 ft * 75 GPM)/10= 1050 W

  18. Mollies Branch • Mollies Branch at high flow 300 GPM (1/2 of flow is 150 GPM) Head 100 feet (100 ft * 150 GPM)/10= 1500 W • Mollies Branch at low flow 150 GPM (1/2 of flow is 75 GPM) Head 100 feet (100 ft * 75 GPM)/10= 750 W
