Chris, Thanks for the reality check on Kohilo. I just tried to get info from them asking for a power curve. No response. If a wind turbine manufacturer can't provide even a rudimentary power curve chart, then it doesn't work. I made one for my first homemade wind turbine simply by watching the anemometer and wattage at different windspeeds for awhile and writing down the numbers I was seeing and then draw the graph. Wind always cooperates and gives constantly changing speeds.
