Roger, etc.,
All reports that have come my way basically concur; with one interesting
exception - that being from a SkyStream owner (and "urban wind dealer").
They are claiming about "500 kWh/per month" from their machine, which is
located smack-dab in the urban heart of San Francisco. This is on a 45'
tower, by the way, right next to a house. Since this reported production
rivals the best turbines in the same rotor size class in a really great
wind site, the report is either extremely misread, or this part of the
city has one hell of a wind regime! It is also interesting to note that
they won't sell any more SkyStreams after having "a negative experience"
with SWWP.

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??

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.
From the others' experience, sounds like we should keep our fingers
crossed.

Added to this was SWWP's extremely 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 Flagstaff.

hoping SWWP would get this one right, but I don't think it's there
yet. 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
