Turbine Tail

Welcome to the Solar Innovation Exchange, home of the Turbine Tail™ kit!

The Turbine Tail™ kit (some assembly required) offers these features not found in other platforms:

  • A long tail moment keeps the rotor disk perpendicular to the wind flow until its self-furling action starts to kick in at around 35 MPH where the forces against the rotor begin to rotate it about the mast centerline. If the forces are great enough it will continue to turn completely out of the wind; this feature effectively eliminates over-speed damage and the need for a brake system.
  • GM style Delco alternators from V8 air conditioned vehicles with frames 10SI and 12Sl converted for turbine use will bolt directly to the Turbine Tail™, other types of alternators such as an Axial Flux project can be adapted with brackets made to fit.
  • Simple pipe thread pole mounting.
  • Maintenance free POM bearings/bushings.
  • Stainless Steel hardware.
  • Heavy Duty powder coated steel construction.
  • Approximately 33 lbs. with alternator and rotor.

A complete system will include the Turbine Tail™ kit with alternator/rotor and these components:

  • Solar panels to suit.
  • Charge controller.
  • Dump load.
  • 6V deep cycle batteries wired in series.
  • 12V to 120V inverter.
  • 3 Phase rectifier.
  • Tower.

There are three options to purchase the Turbine Tail™ kit:

The graph below shows the results of testing the Turbine Tail™ kit with the the alternators listed above. As can be seen, they both start making voltage with a wind speed of around 5 MPH where it increases in a linear motion until the furling action starts and the voltage starts to drop. This exactly what we expect and want in a small turbine. Check out the test rig here.

These videos of the Turbine Tail™ kit show the furling action in testing and in high winds:


Check NOAA for the average wind speeds in your area.

To get the most out of any wind turbine you need to be clear of obstacles and get it at least 25' above ground level.
