Turbine and Tower Details: Bergey Excel-S 10kW Turbine on 100 ft self-supporting lattice tower

Location: 917 Exeter Road, Lebanon, CT

 

Equipment and Testing

 
Testing will be commencing soon on the Eoltec Scirroco turbine.  This testing will include collecting data to verify turbine power performance, acoustic emissions, power quality, and durability; referencing, where applicable, portions of the AWEA draft small wind test standard and IEC 61400.  Monitoring is scheduled to occur for a period of 12 months, from turbine installation.  Progress reports and final report, when available, will be posted here.
