[RE-wrenches] Skystream 3.7 experiences?

Tue Dec 23 16:12:54 PST 2008

I support and second the thoughts and comments Roy has voiced, as the real
world experience does not yet marry up to the projections and subsequent
client/owner expectations.  Without a customer production meter, owners are
basically happy with their units (they rotate so they make power J).   With
production meters you will find a different reaction.  Reality sets in with
the numbers on those meters.  I do not install ANY wind turbine without a
customer side, production meter and I monitor that with annual inspections
and maintenance.  I am hopeful that refinement of the Skystream turbine,
electronics and software will prove to be fruitful and live up to those
projections and expectations.

Phil and all,

The industry insiders have a great saying that sums this all up....

Skystream owners without production meters love their turbines.
Those with meters hate them.....

Let's hope SWWP does what it must to turn this around and do what's right
for 
the industry. Hey...I can dream can't I??

a large number of electrons were terribly inconvenienced.

Our experience with the Skystream here in Wyoming has been good so far.  We
have installed 6, the oldest one being in operation for about 14 months.
One is part of a battery based grid-tie system, and operated well when
tested.  One of the turbines is in world-class wind in Southeast Wyoming.  I
just checked with the owner and it produced about 480 kWh in the last month
on a short tower (with a hundred miles of sagebrush to the windward side) at
almost 6000 ft elevation.  Unfortunately this turbine doesn't have an
anemometer/data logger, so we don't know if it is performing as expected.
My guess is that it spends a lot of time self-regulating.

One of the turbines was in the recent batch of recalls and was dealt with by
a SWWP-hired contractor.  This involved a potential leak in a seal of the
electronics compartment in the nacelle (although for some reason they are
replacing the whole turbine).  While reaching somebody at SWWP tech support
has been nearly impossible, this turbine swap was handled fairly swiftly.

poor customer service. They took several days to even call us back, didn't
send promised parts, etc. Of course, these two installation sites are one
and two hours from our shop. We had one customer who was just about ready to
throw the unit in the back of his truck, and drive it the five hours up to

Given the long and well documented SWWP history, I was afraid of this. Has
anyone successfully coupled a Bergey Xl.1 to a grid-tie?  Anything else to
recommend in the 1-5 kW range? thanks... > Might have something to do with
