    specialist job for a good one.

    the ones diy sheds offer includes survey and installation.

    IMHO they are too small to provide a return, and the bit that tickles me is they are only g'teed for 5 years but you will get your money back after 10 years assuming it lasts that long

    also apart form being a fad, i thinkl they will be like the white meter, if every one gets a good one, the price of leccy will go up to compensate the the low sales of leccy

    even thats being a bit optimistic, the one offered by the orange and black shed costs a grand and half and is rated at 1kw @ 12.5m/s

    I looked up the average wind speed for this area to be ~6m/s, doesn't look too bad on paper does it? but remember that the power is proportional to the windspeed cubed, so (6³/12.5³)*1000 gives you a power of 110w looks rather less impressive now doesn't it?

    My electricity averages out at ~7p per kwh (taking into account night rate), over ten years it'll have hae saved you 0.11*24*365*10*0.07 = £674

    Not looking so good now is it? also note that it says something like a wind speed has to be maintained to get an optimum output, gusts don't produce a power in keeping with the average, so knock a little more off there.


    Too much hype, vested interests and government grants in this area atm...

    we are talking the same one.

    i never said it was any good, far from it, in our b & q when they first had it it was on prominent display with a bloke, now its pushed to an obscure corner (where it belongs)

    some people do live sucessfully off grid with minimal use of generators

    it requires an attitude shift though, grid connections charge a fair bit for the connection (for initial installation and then either as a standing charge or as a high initial rate) but the electricity is fairly cheap.

    off grid systems by contrast have little in the way of standing charges but it becomes expensive (either in fuel for generators or in upfront costs for renewables) to use a lot of power. The result is if you want to make it work you have to be very efficiant in the use of electricity.
