Skystream Clone?

I missed this one at the AWEA conference. I just received an e-mail from "Hopeful Energy". Looks like there is a possible clone of the Skytream. It's from China, from a company formed in 2003. They offer a 5 year warranty on this downwind model they rate at 5kW output @ 12m/s with a 4.1m rotor. I wonder if the NREL has tested it?

Does anyone know anything about it or remember seeing it in Chicago?

Re: Skystream Clone?
swwp is now affiliated with a chinese company and this may be the same one you are referring to. i don't remember the name of it, but i'm sure it was placed on the forum somewhere and i'll give you odds where that is. -

This appears to be the Chinese Mfg. of the Skystream + SS CloneTruth Squad wrote: »http://www.air-yunsheng.com/en/products_list.asp?id=25
Scroll down to see country of origin on this:

Beyond that, I have no more comments on SWWP. People need to do their own due diligence. I just felt this last thing needed to be posted.

Re: Skystream Clone?
appears to possibly be separate companies. maybe they are now ripping off swwp like swwp was ripping off its customers? -
Re: Skystream Clone?
Here is a snip from the e-mail:
The Airforce 4.1 model is independently-tested CE-certified, utilities gearless,
direct drive architecture, unique permanent magnet generator, and integrated
SMA inverter to provide best-in-class wind energy capture. Also, the Airforce
4.1 requires minimum maintenance, carries industry standard 5-yr warranty
They included a pdf brochure of the unit. It is no surprise that a Chinese company is copying, if at least partially, the SS3.7 design. It seems there are numerous Bergey XL1, AIR303/403 and Whisper 100/200 clones out there now. At least with this turbine the inverter is a SMA ground mounted product. -
Re: Skystream Clone?
LOL!!!!!!!:p
That absolutely is a copy of the Skystream. Basically, it's the Skystream minus the hatch cover and different blades. Even the yaw cover is the same. But I doubt SWWP authorized this copy. Serves them right. You know what they say: You lay down with dogs, you wake up with fleas. You do business with China, they copy your product and sell it themselves.
I love the name: "Hopeful Energy". Boy, they got that right! -
Re: Skystream Clone?
And they may have even improved on the old SS... They are using an off-the-self wind GT inverter on the ground. Cloned and pwned.

Re: Skystream Clone?
You can also bet the price will be much lower than Skystream. They'll probably go after SWWP's current customers, as well as their hoped-for accounts. And, indeed, they got it right as far as using an off-shelf inverter and putting in on the ground. However, before Hopeful Energy can compete, they have to get their turbine UL listed to sell it here for grid tie. -
Re: Skystream Clone?
UL / NRTL should not be a big issue for Hopeful if this factory produces other product for sale in the US--They probably already have the basic infrastructure...

Re: Skystream Clone?
It will be interesting to watch this one. That they chose an off-the-shelf inverter tells me they've done some research, if you know what I mean.;)
