I mounted this turbine in my back yard on the recommended schedule 40 galvanized pipe at about 20' high. My location does not get consistent wind from one direction which is the only way this turbine will spin. Even in gusty conditions of 15-20 mph the turbine rarely spins more than a few revolutions and has not produced any measurable power after a month. If you don't have a steady wind from one direction this turbine will not produce any power at all. You would be better off with a vertical turbine or one with larger blade surface area. The specs say 8 mph start up, that means a consistent 8 mph wind from a single direction. For the money you would be better off with a single 80 watt solar panel.
This solar resource map provides a summary of the estimated solar energy available for power generation and other energy applications. It represents the average daily/yearly sum of electricity production from a 1 kW-peak grid-connected solar PV power plant covering the period from 1994/1999/2007 (depending on the geographical region) to 2015.
