be careful (rethink location?) as it will shake the wall to bits sooner or later sooner for an old wall

Hi Fisher,

Tony is absolutely right. Locating a turbine on a gable end will possibly result in structural issues and the turbulence from your building will seriously affect the turbines performance so much so that I can guarantee you'll be disappointed with the results.

I would recommend you consider positioning the turbine in an location with a relatively open path from the South West ( If your not in the UK take a look at www.windfinder.com and see where your prevailing winds are coming from) and depending upon your engineering skills either manufacture a simple mast yourself or have one made.

From there you will require a control unit to suit the turbine and then if you want a grid connected set up you'll need a small inverter. It won't be cheap I'm afraid as there are a number of other bits and pieces like Isolators, breakers, a meter to name but a few.
When you take into account what's needed to get up and running you may well find such a small turbine is simply not viable, but allot will depend on how much you can do yourself and how cheaply you can source the components.

Kind regards

Paul

In order to connect to the grid the entire system has to be certified as being G83/1 compliant.

Posted By: fisher4772ok thanx guys the wall should be ok its 5ft thick stone and has been ther a long time but looks in good condition,as for siteing its very open with a height of 978 ft above sea level and a open plane each side of 20-30 miles no obstructions.?
Does the invertor accept the direct three wire connection or do i need other equipment....ive looked at istallation legislation and found nothing stating I require certified installer except for the final grid connection?

I think the problem is that the roof will cause a great deal of turbulence around the turbine, reducing its output dramatically. Even if it's on the windward side of the building, there will be a lot of air hitting the wall below it, eddying about and moving upwards to flow over and around the building. If you were able to position it upwind of the buildings (for the prevailing wind direction), on a pole, as far away as possible, you'd get much more power out of the same turbine.

is that a wire off each of the three coils, or is it a ground, +ve and energize wire (or whatever its called)?
