Power curves are available for most turbines if you ask but what they really tell is "what is the MAXIMUM power the turbine puts out at some wind speed". That's not the same as "how much energy per hour can the turbine produce in real wind". This is because controllers, turbulence, blade mass, furling systems , turbine efficiency and other factors all combine to generally reduce watt hours of production depending on the way the turbine behaves in gusty or high wind conditions versus steady wind, or when it furls or not.

The WIND ARROW power curve (more correctly an ENERGY Curve) is unique in that it shows the REAL ENERGY you can expect from winds up to 60mph (27m/s). If the wind is relatively steady at some wind speed the chart shows how many watthours will be produced each hour. Other turbine power curves only show the instantaneous power at some speed and ignore the furling time spent "out of wind" for example. That means part of the time the turbine is actually not producing at all. Most other small wind power curves end at 30mph (13m/s) or imply that they actually produce steady power above 30mph. In fact those "power" curves may reach the power level shown from time to time but for such short periods before they furl, that the actual energy they produce over an hour at that speed is minimal.

WIND ARROW Energy curve is showing you the true ENERGY production potential of the machine in all wind speeds. You may wonder why we drop the power so much after 30mph. It's a very conservative approach to make the turbine last longer, so it does not have to work right up to it's limit. We could make it fly at a higher power level and make the power curve look better but it can shorten the life of the machine and since it does not happen that often why work it so hard for those extra watts. In fact any other turbine with a furling system or mechanical brake is either shut down or intermittently producing small bursts of energy as they come in and out of wind so the actual energy production is a either zero or a very small fraction of the peak power thy show you.

The WIND ARROW's Active Flight Controller (AFC) actively flies the blades at the optimum power for the wind speed and above 30mph it will produce a steady 200-600w fully under control . .  with the ability to safely start or stop the turbine with the flick of a switch. No mechanical furling or braking system means few parts to wear out or fail and a longer worry free life. The pitch of the blades and custom software can also be ordered to achieve optimum performance in seasonal low or high wind, or high altitude locations.

WIND ARROW Power Curve and Annual production capability is UNIQUE for it's cross-section. Larger machines are coming.
