How to take a turbine down

craigkcraigk Posts: 2Registered Users
Hello. I have the opportunity to get a skystream turbine and 33ft monopole for free, but I have to take it down. Other than needing a tractor, can someone tell me, and illustrate an example of the gin pole/method I would use the get the tower down, without spending alot of money? The pole has a square base, and a eyelet half way up. Thanks.

    Do you want the SkyStream? There were a lot of issues with the MonoPole (pole was difficult to maintain perfect vertical, and Skystreams did not track wind very well when pole was not vertical). Also Skystreams had a fair amount of electronics problems (which were mounted in the Nacel 10 meters up).

    I have not seen any information on the "new" mfg. Xzeres versions.

    Do you have a very windy site for the turbine install? And how much it will cost (concrete footing)?

    Thanks for the links, mike95490. Hello Bill, I don't want it if it is going to cost alot to take down and repair. I would have to put it on a higher tower to work at my place. The cost of a footing might be roughly $600-1000cad. Its just a thought, and nothing I'm dead set on doing.

    Generally, the cost of a tower and footings is much more than the turbine itself (add cabling, battery charging--if needed, etc.).

    There are freestanding towers, and there are tilt up towers with guy-wires (which can be a lot cheaper--used ground anchors--screw-in anchors instead of lots of concrete). And you want to install the turbine+tower away from occupied homes/buildings (throwing blades, falling turbines, and even the occasional falling tower can happen).

    I have heard/read zero about the Skystreams with the new mfg.... So I do not know how the earlier issues have been addressed.

    Do you have any wind turbine installs in your location (or data from this existing installation) to see how many kWH per month they have produced over several years?

    I will be honest, I am not a fan of wind, especially of small wind) unless there is no other choice. This is one case where DIY (do it yourself) products seem to exceed the capabilities/quality of commercial products. But not a lot of people have the skills and equipment needed to build and install these mid-size turbines.

    Hopefully, some other folks can give updates on the New Skystreams and how they are working out.
