Residential Microhydro System Project

Question: What is a residential Microhydro system project?

Answer: A residential micro-hydro system consists of a small turbine in a creek that produces energy that is transferred to the home.

Residential Microhydro System Project

Our S-Tek Building Solutions’ green energy division expert, Jason Smith recently completed Appalachian State University’s Microhydo System Design and Installation Workshop gain further knowledge of the industry. This two day continuing educational activity was held in Boone, NC and was instructed by Don Harris a national microhydro expert. Harris has developed residential hydro systems since 1981 and is responsible for nearly 3,000 successful systems. The Harris system is an efficient, durable battery charging Pelton Wheel designed turbine making it the most popular micro-turbine in the US.

Workshop participants covered the basics of small scale hydro power with a field trip to local microhydro installation. Jason was able to increase his current knowledge about site assessment techniques that will further enhance our current projects. The workshop included:

  • Measurement of head and flow
  • System design
  • Types of turbines and their associated performance and cost
  • System components such as the intake, penstock and balance of system
  • Maintenance and troubleshooting
  • Case studies
  • Valuable tips from  industry icon, Don Harris.

S-Tek is pleased to share photos from an active Microhydro project, at Mollie’s Branch located in Boone, NC. Photos taken by Jason Smith. For more information on a residential microhydro project or to speak with Jason, contact our office at 864-888-1620 or email Jason at
