Hi All, my annual report on production from my Bergey Excel  with the
Gridtek inverter on a 120 ft tower in NW Iowa.  My production was 14,192
kwh, even though my wind speed at the local airport was only 10.2 mph (13.4
mph adjusted for hub height).  Oddities included Feb. being my second lowest
month for production 729 kwh (wind speed was only 9 mph for the month, when
it should have been closer to 12).  I also had three different days where I
partially furled the tail to try and avoid inverter shutdowns.  I had two
days in a row with very similar average daily winds (29.0 mph and 29.8 mph),
the first day I did not furl the tail, had 22 five minute inverter shutdowns
for protection and produced 169 kwh for that day.  The next day I partially
furled the tail and had stronger winds, but produced only 161 kwh that day.


Overall, it was a good year for production, between the wind and 2 KW of PV
I produced 969 kwh more than I consumed for the year.  Anyone else have
annual production numbers to report from there turbines?

Monthly numbers below,   Thanks,
Paul Rekow

Hello everybody,

I'd like to list the different tariffs that exist all over the world for the
electricity for small wind.

As a beginning, in France, there is no specific FIT for small wind so the
general tariff is 0.082€/kWh.
It's then better to consume the electricity produced than to inject it on the
grid, electric power can be valued at 0.112€/kWh.

Thanks a lot,
have a good day

These are the best turbines I have seen. I contacted the company about prices
and they seem a bit spendy to me: 5Kw for about $32,500; add 5 grand to make it
turnkey/grid-ready, and another $10 grand for a 60 foot tower; and, you have $50
grand wrapped up in the thing. If you already have a tall building (or silo) the
tower costs can come down.

But, all in all, they appear to be the most stable (30-yr. life), low
maintenance machines on the market. I wish that I had come up with this design.
Although I won't be buying one unless the cost comes down, perhaps someone here
will want one.

Hi skrewtz,

Have you actually seen them in operation?

Has the company been around for 30 years? (the video actually says
15-20 year lifespan, but I bet they don't have anywhere near that
many years in the field.)

Claims are easy to make...

Don't use a building or silo -- not a great idea at all.

And don't wish for lower cost, since that generally means lower
quality, which means shorter life.

The vid repeats several of the false "advantages" of VAWTs.

I'd wait and see how this actually performs, and compare it to
equipment that's been on the market for a while.

the thing.

Wow, seems like solar beats that hands down.  Solar panels are now $2/watt
wholesale.  That would be $10k.  Plus $2k for the grid inverter.  Or only
about $12k plus installation for 5kW.  And it should last 30 years with
little maintenance.  I cannot imageine a turbine lasting that long without
expensive issues.

OOPs the difference is 5hrs a day solar, and 24 hrs a day for wind.
NEVERMIND!  *Wind* wins.... but just barely...

(Unless of course, the 5kW wind turbine is not putting out 5KW all the time
(which it wont)...  To the degree that it is not putting out 5kw 24/7/365
ALL the time, then it is less cost effective than solar.

Or in that order of magnitude anyway...

I watched all 3 of their videos, and like (I think) EVERY single VAWT video I
have seen (except for one that I took once of a Windspire), nobody seems to want
to show any pictures of an power meters or voltage and current !

You would think that they would want to show you some actual power being
generated by their unit other than just a video of it spinning.

Also, I could not find anything except these videos about the product.  No specs
or anything.  Just a picture of a dandylion with the seeds being blown off.

Subject: Members experiences with turbines around 3KW
wayoffgrid
Send Email Send Email
 
Anyone care to recount their experiences with turbines with an output around 3KW
? I ask because the time has come to replace my turbine.

I have lived, for some years, with a Bornay Neo Inclin 3000 and the experience
has been largely a bad one. The Bornay equipment has suffered many, many
failures but I had a great supplier who kept me going with a mixture of advice,
parts and a generous measure of commiseration. Unfortunately, this supplier has
gone under. the pressure of supporting equipment without the help of the
manufacturer appears to have done for him.

I rely on wind power as the main component of my power system so have decided to
junk the Bornay for something else. I have no experience of other kit so
wondered if those who have might care to share those experiences.

I appreciate that all turbines will suffer some failures along the way but I am
looking for kit that will help minimise my failure rate, from a manufacturer
that will stand by its products.

Any ideas ?

Thanks

Hi wayoffgrid,

Can you tell us more about your situation?

Site details, tower height, average and peak wind speeds, years in
service, supplier, etc.?

That might help list members make recommendations.

In general, you get what you pay for -- if you want more robust;
spend more money up front.

Also, if your tower is short and your site is turbulent, you'll have
more problems.

I'm also wondering what specific failures your experienced.

Regards,

Ian

Hellos wayoffgrid,

Could you please let us know more about your problems? And of course where your
windturbine is installed?

As a personal of the company and family Bornay, there is not admissible to me
this kind of information, because as you probably knows, around Bornay there are
a lot of persons trying that this do not happens, but of course sometimes
happens.

You have our technical department available to solve you any problem you have,
but first of all I don't understand why you don't contact the factory directly
to solve your problems.

Please give us the requested information in way to help you.

I would recommend the 3kW unit from Kestrel, the e400i.
 
Do not use the SWWP Whisper 500. No better than the Borney if not worse.

Next time our turbine is down, I would like to fit something to record the
number
of revolutions per minute, time and date. The main shaft of the turbine is about
1 1/2 or 2" diam. and easily accessible.

Maybe someone can suggest something suitable?

Easier job is to place a small magnet on the shaft and place a detector  ( hall
effect, or a  Reed switch, or a coil) on the generator casing and very close to
the magnet that when rotating the magnetism is detected generating a pulse that
can trigger a monostable with a certain ON time that can be used to either
calculate the RPM or the pulses integrated to feed a meter indicating the RPM as
well.

The problem is the rotation of the wind mill to follow the wind direction if the
mill does not have a set of slip rings to pass the signal to the area needed.

Of course other techniques can be used to send the signal via a small
transmitter if low power is available for the circuit.

Wouldn't it be easiest to just count the waveform peaks in the wind generator
output? That doesn't have to be done up the tower, right?

Why not just use the turbine's 3 phase output and measure frequency?  If you
know the number of poles in the alternator you can calculate RPM based on the Hz
reading between two phases.  No extra parts or mods to the turbine!  If needed,
a frequency transducer can give a low voltage signal that can be used for an
input to a data logger.

Best Regards
Corey

Tom,

If the Proven output is 3-phase, you can count pulses per revolution across
two phases, if DC output, there might be enough ripple to still detect
pulses and count them.

Hello everyone,
i live in south florida on the ocean and have prevailing winds all the time. I
am a retired business person with no mechanical electrical expierence. I viewed
a tv special showing the latest type wind turbine that has a built in Invertor
and our electric company, florida power and light does have a program of
allowing me to return electricity to the grid when my house does not use it.
thus, my first question is this. I used 1,715 Kwh last month on my bill.
if i were to purchase a 10kw wind turbine, what does that mean. i cannot find
this answer on the web. does the turbine produce 10kw per hour with ideal wind
speed or 10kw a day. it seems that if it were 10kwh a day, that would only be
300 kwh a month and not worth the investment.
anyone who wishes to help educate me would be greatly appreciated. referring me
to some websites would be great too.
thank you

What Chris says is true. We have done this. In fact I will bet you that
your inverter will even tell you the frequency. Then just find out how
many poles there are and do the math.

Tom;

APRS World makes the sensor board you need. It filters noise out of
the AC waveform, and converts to pulses you can log with one of the
extra channels on their Wind Data Logger.

Gino -

I will try to provide a quick and easy explanation of the difference between kW
(kilowatt) and kWh (kilowatt-hour).

If you purchase ten 100-watt light bulbs, you purchased 1 kW worth of light
bulbs.  If you bring them home and turn them on for one hour, you will use 1 kWh
worth of electricity.  kW is often referred to as demand or potential and kWh is
consumption or generation.  In other words, kW is the beer in your refrigerator
and kWh is the way you feel after you have consumed it.

For a wind turbine it is a little more complicated.  The 10 kW is the rating of
the turbine, same idea for a 5 horsepower motor.  If the wind blows at the rated
wind speed (typically about 25 mph) for one hour the turbine will generate 10
kWh worth of electricity.  There are web-sites, wind maps, and software that can
help determine your average wind speed and from there, with a few assumptions,
most turbine manufacturers can provide your estimated energy production.

I hope this helps.

A 10 KW wind mill means that the mill  with  28 MPH wind will be able to produce
10 KW constantly during the time the wind is flowing at  28 MPH .

Therefore if the 29 MPH wind  lasts  6 hours ,the wind mill be producing  10 KWH
per hour or a total of  10 KW * 6 hours = 60 KWH in those 6 hours .

If  the wind, assuming (this is non a real available wind condition) that the
wind with 28 MPH continuous for exactly  30 days - the wind mill will be
producing:

10 KW * 24 hours/day * 30 days  = 7200 KWH/Month.

To  cover your needs of 1715 KWH/month the wind mill may require to produce in a
daily basis :

1715 /30 days = 57.17 KWH/DAY  --- In a realistic way, the wind mill may require
a wind velocity throughout the 24 hours day to produce such  57.17 KWH/day  in a
sense :

57.17 KWH/day / 24 Hours = 2.382 KHWH -- still not practical, because we need to
examine the site wind regime,you may have during the whole year to estimate what
energy can be  harvested to determine hour to supply your energy needs.

The  first step in this process  is to change Your attitude of energy usage and
define how to reduce the energy consumption to improve the chances of obtaining
the necessary energy harvesting levels.

Then the analysis of the investment to determine if it is a good idea to install
a wind mill -- analyzing the total cost of the installation, maintenance and
life of the wind mill .

Hello

Anyone ever hear of this failure mode??

I have an old Jacobs model 45 powering my house
down here in the caribbean
had her for 32yrs
  rewound to 110v  in the 60s (those hippies)

I was awoken a few weeks ago to loud bang crash, somthing hit the roof
it's 4am (dark).. and then I'am hearing the sound of a very badly ballanced wind
generator
wind was 25-35mph ...run to the turnoff crank and she will not fold
the mast is shaking very badly so i climb, push her out of the wind
and tie off to see 1 blade broken in half and tail spring missing

So it appears the tail spring broke at the tail loop and sprang foward
striking a blade

thanks

For those concerned about VBINE performance claims. Here's the last few emails
I've received.  I will attempt to post the PDF pamphlet that came along with the
Jan. 23 email.

Hello Brent,


We have sent one of our turbines, at a cost of over $100,000.00, to the Canadian
Wind Institute (CWI) in P.E.I. to perform testing and to provide us with data
verification on its performance.

We wish all turbine manufacturers were required have their turbines tested by
the CWI because some of the claims other turbine manufacturers make do not come
close to what they actually produce.

Of course we have done allot of our own preliminary testing and have had  good
results but we are looking forward to receiving the verified/certified data from
the CWI.

Thank you

Thank you Wes,

I will very much like to see VBINE's power curve and other stats
verified/certified. I have 2 potential properties in NS - one gives an average
wind of 7 m/s at just above the tree-tops and the other runs at about 5.5.  Both
properties border the sea the so there is usually some bit of a breeze everyday
- particularly fall, winter and spring when the need is greatest.  I'd really
like to be able to generate enough power at the 5.5 m/s property, but at $32,500
per unit, it seems like I'd be shelling out $90 grand even if I build the
towers!  That's alot of up front cash.

I will forward info I get from VBINE (including your email) to a group (of over
5000 members to which I belong).  VBINE is getting traction from me.  At
present, the up-front cost is too rich for me.

Hello Brent,

Our Director of Sales, Dwight Siman, asked me to follow up with you to make sure
you have been contacted  in regards to the email you sent us last month.

We are currently manufacturing and installing our wind turbines. As a result of
our progress we are in the process of building a new 30,000 sq. ft.
manufacturing facility.

This will help us keep pace with the growing demand for our product. It is an
exciting time for VBINE ENERGY and we are very proud of our product.



The following points are what make our product different from the traditional
horizontal axis wind turbines(HWAT).



1.       Self starting in low wind 1.2 meters per second or about 2 miles an
hour.

2.       Does not have to turn into the wind to start turning, takes wind from
any direction.

3.       Small foot print, less than 3 meters wide.

4.       Produces full power at 11 meters per second.

5.       Low rate of rotation, 120 rpm to produce 5kw (about 35 MPH tip speed)
compared to a tip speed of up to 190 miles an hour for HWAT.

6.       Safe for the environment ( Birds Bats).

7.       Low Noise 66db at 15 feet ( less than the noise in the cab of a new
Chevy Truck at idle).

8.       Operates in extreme conditions due to low rotation speed.

9.       Roof mountable on commercial buildings ( we have installed a unit on
the roof of the David Suzuki School in Windsor On).

10.   We have applied for certification from the Canadian Wind Institute to
certify our KW and power curve.

11.   No shadow flicker ( has been blamed for everything from headaches to heart
problems).

12.   The top of our turbine does not rotate making it an excellent and only fit
for Telecom towers.

13.   Does not give off any RMF as the rate of rotation is low, also makes for
the right choice for telecom towers.

14.   Very low maintenance because of the design (no drive shafts, gears,
bushings, brushes).



I have attached a couple of photos of installed turbines as well as a copy of
our advantages brochure that explains some of the unique features and advantages
of our turbine.



The pricing of our turbine is as follows:

Our turbine sells for $32,500.00 + tax.

Tower price depending on height required is approximately $9,900.00 + tax.

Installation depending on soil conditions could be approximately $3,000.00 to
$5,000.00 + tax.

It can be tied into an existing power grid or it can used with a battery storage
system (additional costs required for battery storage system).

We are currently looking at expanding our dealer network. We look at each
dealership applicant on a individual basis.

Please contact me if you have any questions. I look forward to hearing from you.

Thank you

I use the DATAQ loggers but the lower cost units require a PC be attached
for logging.
The more costly are stand alone.   All depends on your budget.     Their
software can change units from pulses to other units like RPM.
You might want to also log wind speed/direction on a 2nd and 3rd channel,
and possibly charge/output current on 4th channel.

Interesting, 100,000 for performance testing, indeed this will rise the cost of
the wind mill  greatly.

What I do not understand is being so high, why the blades are not longer for
higher harvesting levels.

One of this group member, Raul could give a more precise analysis on this type
wind mill.

I've spoken on the phone with a company engineer, a Vice President, and their
head of sales.  They aren't messing around. They have 4 patents and in order to
hook to the grid, they would have to be UL tested too. They have $4.5 million
invested. A 30,000 sq. ft. factory, $100,000 is all part of the price to market
this mainstream.

UL = Underwriters Laboratory, a Canadian safety certification company for
household and commercial appliances. Back in the 80s when I was putting together
a patent for a fireplace insert, UL approval would have cost me $50,000. I
wouldn't doubt that it is easily 2-3 times that now.  They have upfront costs
that they are willing to cover.

I think their generator design is going to prove to be state-of-the-art,
especially in icy/snowy applications. The generator employs maglev priciples so
the bearings do no work except when the unit is moving very slowly.

All the best to you Nando,
Brent

by the CWI because some of the claims other turbine manufacturers make do not
come close to what they actually produce.

     Of course we have done allot of our own preliminary testing and have had
good results but we are looking forward to receiving the verified/certified data
from the CWI.

     Thank you Wes,

     I will very much like to see VBINE's power curve and other stats
verified/certified. I have 2 potential properties in NS - one gives an average
wind of 7 m/s at just above the tree-tops and the other runs at about 5.5. Both
properties border the sea the so there is usually some bit of a breeze everyday
- particularly fall, winter and spring when the need is greatest. I'd really
like to be able to generate enough power at the 5.5 m/s property, but at $32,500
per unit, it seems like I'd be shelling out $90 grand even if I build the
towers! That's alot of up front cash.

     I will forward info I get from VBINE (including your email) to a group (of
over 5000 members to which I belong). VBINE is getting traction from me. At
present, the up-front cost is too rich for me.

     Hello Brent,

     Our Director of Sales, Dwight Siman, asked me to follow up with you to make
sure you have been contacted in regards to the email you sent us last month.

     We are currently manufacturing and installing our wind turbines. As a result
of our progress we are in the process of building a new 30,000 sq. ft.
manufacturing facility.

     This will help us keep pace with the growing demand for our product. It is
an exciting time for VBINE ENERGY and we are very proud of our product.

     The following points are what make our product different from the
traditional horizontal axis wind turbines(HWAT).

     1. Self starting in low wind 1.2 meters per second or about 2 miles an hour.

     2. Does not have to turn into the wind to start turning, takes wind from any
direction.

     3. Small foot print, less than 3 meters wide.

     4. Produces full power at 11 meters per second.

     5. Low rate of rotation, 120 rpm to produce 5kw (about 35 MPH tip speed)
compared to a tip speed of up to 190 miles an hour for HWAT.

     6. Safe for the environment ( Birds Bats).

     7. Low Noise 66db at 15 feet ( less than the noise in the cab of a new Chevy
Truck at idle).

     8. Operates in extreme conditions due to low rotation speed.

     9. Roof mountable on commercial buildings ( we have installed a unit on the
roof of the David Suzuki School in Windsor On).

     10. We have applied for certification from the Canadian Wind Institute to
certify our KW and power curve.

     11. No shadow flicker ( has been blamed for everything from headaches to
heart problems).

     12. The top of our turbine does not rotate making it an excellent and only
fit for Telecom towers.

     13. Does not give off any RMF as the rate of rotation is low, also makes for
the right choice for telecom towers.

     14. Very low maintenance because of the design (no drive shafts, gears,
bushings, brushes).

     I have attached a couple of photos of installed turbines as well as a copy
of our advantages brochure that explains some of the unique features and
advantages of our turbine.

     The pricing of our turbine is as follows:

     Our turbine sells for $32,500.00 + tax.

     Tower price depending on height required is approximately $9,900.00 + tax.

     Installation depending on soil conditions could be approximately $3,000.00
to $5,000.00 + tax.

     It can be tied into an existing power grid or it can used with a battery
storage system (additional costs required for battery storage system).

     We are currently looking at expanding our dealer network. We look at each
dealership applicant on a individual basis.

     Please contact me if you have any questions. I look forward to hearing from
you.

     Thank you

Hi Nando,

I would have preferred to see some experimental data, or at least the
theoretical predictions from the manufacturers, before making a comment about
this rotor, but since you are pulling my tongue and considering the interest of
the audience in this respect, I would advance some observations.

First at all, this rotor is already known as the Lenz Turbine as you may see in
the following link.
http://www.instructables.com/id/VAWT-Lenz-type-Stage-1-Converting-wind-power-to-\
/

Has VBine Energy acquired the patent rights of this turbine?, and if so, Why
they don't mention it?  Or maybe they are referring to other inventions not
shown in the pictures, which might be meaningless, considering that a slow
rotating generator with a fixed central stator is no innovation at all.

It is striking that having announced such big investments in the construction of
a manufacturing facility and claiming a big demand, not a single graph,
specifications nor test data have been published. More surprising is that
classes for training of dealers are in full swing as shown in the web site.

The staff of the Company does not show any engineer in charge of the technical
development.

VBine Energy is claiming 5 kW of power delivery at 11 m/s, but does not mention
the cross-wind area of the rotor.

From the technical point of view the Lenz/VBINE rotor is an upgraded Savonius
with a probable efficiency not higher than 20%. The high solidity of the rotor,
almost 100%, doesn't let to expect a better performance.

One point in favor is the main intended application for energizing the
telecommunications antennas, only in this case the performance of a wind turbine
becomes less important, because there is no price limit for the fullfillment of
this critical need.

Interesting, 100,000 for performance testing, indeed this will rise the cost of
the wind mill greatly.

What I do not understand is being so high, why the blades are not longer for
higher harvesting levels.

One of this group member, Raul could give a more precise analysis on this type
wind mill.

For those concerned about VBINE performance claims. Here's the last few emails
I've received. I will attempt to post the PDF pamphlet that came along with the
Jan. 23 email.

Hello Brent,

We have sent one of our turbines, at a cost of over $100,000.00, to the Canadian
Wind Institute (CWI) in P.E.I. to perform testing and to provide us with data
verification on its performance.

We wish all turbine manufacturers were required have their turbines tested by
the CWI because some of the claims other turbine manufacturers make do not come
close to what they actually produce.

Of course we have done allot of our own preliminary testing and have had good
results but we are looking forward to receiving the verified/certified data from
the CWI.

Michael,

First I have to say that climbing a tower to secure a spinning wind
generator in 30 mph winds is insanely dangerous and no one should get the
idea that this is appropriate.  Now in answer to your question, no I have
not heard of this failure before.  You should take a good look at the pieces
and see if the physical evidence is consistent with this sequence of events.
For instance it is entirely possible that the spring has been broken for a
long time and no one noticed until you needed it to furl the machine.  If
that is the case it could be that the wood blade has just rotted over the
years and failed.  Springs do fail most commonly at the sharpest bend and
that is usually at the bend to form the hook in a tension spring.  It will
be interesting to inspect the pieces and construct the probable sequence of
events.  In any case you will need a new spring and new blades.  Do you have
a blade activated governor or a fly ball governor?

REgards,
