Hi Michael The first thing in design of a RE system is to know the load. What is your load? Will the families be closer to 3 or 30 kWh per day? How many...

Hugh, Are you taking 10-minute or 1-minute averages? If not can you average the data into these intervals later and publish a Scoraig Wind power curve for the...
Hugh, Be careful with using a R.M. Young Wind Monitor in doing power curves in turbulent wind. A 50' tower probably gets you into turbulent winds (TI > .20)....
