| Last year I bought a DanB turbine as well as some more solar panels. The combination has pretty much forced me into building a power shed in a place that is OK for wind power and solar, but not so good for any other structure (no shade and too much wind!). Unfortunately, it's not so good for a tower either - it's just not very flat. To make use of the normal tilt-up type tower, it would have to be raised and lowered with only one side guy. I've been toying with the idea of a fixed gin pole planted in the ground and then pivoting the 40 foot tower over the top of the gin pole. I've sketched it out in OOdraw and saved it as a pdf. It looks like I can't show a pdf here? If you know how to look at it, feel free.
The gin pole would be a rather large diameter 20 foot long schedule 40 pipe (like well casing) that is sunk and anchored as deep as possible in the very rocky ground in that spot. I was also thinking I could use four permanent guys from the top of the gin pole to keep it solid. The main difficulty this idea presents, I think, is that the tower head will be partially inverted when it's lowered. I don't want it to fall off! So some sort of retainer would have to be added to the turbine and tower top. A big advantage is that it should be much easier to raise and lower.
Is this a really bad idea?
