Re: payback times

If payback is important to you (as it probably is to most!) you need a turbine with both high efficiency and excellent reliability. A turbines not much use for payback if it spends weeks or even months broken down and waiting spare parts!

The "comparison of production chart" on this site is a good resource to see what turbines are both the most efficient (kWh per month vs NOABL windspeed) and also the one that are most reliable (those that dont have months with inexplicably low monthly production figures...)

Aside from that, its al Location, Location, Location. Put the turbine in the wrong place, or in a low wind speed site, and payback will extend dramatically, often by many many times.

In a good windy location like the North of Scotland, a turbine like the Eoltec Scirocco 6 kW is expected to achieve payback in 5-7 years, assuming current energy prices and "double ROC's" as of the 1st of April 2009. Turbines already installed are well on the way to achieving this, by producing between 18,000 and 25,550 kWh per annum without any stoppage time or breakdowns!
