Wind-solar Hybrid System Set for Release This Month

One of the biggest names in distributed wind has teamed up with a solar technology company to develop and offer a wind-solar hybrid system that will be available as early as this month.

Distributed wind turbine producer Southwest Windpower Inc., and Advanced Technology & Research Corp. (ATR) announced an exclusive strategic alliance to design and manufacture wind-solar hybrid systems. But while the announcement of the partnership came this week, the companies have already developed what they are calling “the first fully integrated wind-solar hybrid system of substantial capacity.” The combination of advanced small wind turbines with microprocessor-controlled solar tracking technology delivers more consistent energy and represents a new chapter in small-scale, on-site power generation, the companies said.

Southwest Windpower’s initial wind-solar offering, named Skystream Hybrid 6, uses a Skystream 3.7 wind generator, six solar panels and a GPS-controlled tracking mechanism that rotates the panels to capture the best available sunlight. The tracking mechanism delivers up to 35 percent more energy than fixed panels on a rooftop, according to the companies. The solar panels and tracker are mounted on the wind turbine’s tower, which minimizes the system’s visual impact and reduces the costs compared with separate systems. State and local incentives for solar and wind systems can reduce the overall costs significantly in many locations.

The Skystream Hybrid 6 will be available initially in the continental U.S. later this month, followed by worldwide rollout through Southwest Windpower’s global distribution network.

@anonymous. Not sure your comment is completely accountable. Let's address the 'substantial capacity' factor which you left out of your quote. Ampair may indeed have been one of the first to deliver a fully integrated wind-solar hybrid system, but their wind turbines have also had a great deal to be desired, especially in the built environment. One only has to look a the performance data results of the Warwick Wind Trials where manufacturers' claims were inflated and in-use capacity factors averaged around 0.8%. And sadly, performance data on the high rise buildings where the the Ampair 600 230 was used reported the poorest showing where energy output from predicted measured wind speed vs. energy output measured was concerned, and in-use capacity factors that were reported at 1.49%-1.66%. Not to mention, And yes, there were also other factors involved in these poor showing e.g. siting, installation.

NB: I just took another quick look at the Ampair WWT data, so I could substantiate my claim on this note.

Truthfully, I could care less who was 'first.' I'm just glad to see more than one player in the market, so more early adopter systems like these can become a bigger part of the hybrid renewable energy systems opportunity mix.

I think you will find that UK company Ampair has been making "fully integrated wind-solar hybrid systems of substantial size' for some time. Therefore the use of the term "the first" is possibly a little misleading? Was this release sent before or after SW fired their marketing manager?

Hi, Bill,
My inventions are worth billions of Euros and would bring savings in size of quadrilions if installed in sufficient numbers.
But if they do not get informations that my inventions exist, how could they know it?
I thinbk my WindSolars could save the World from Global Warming (since with cheap electricity it is cheap to permanently remove CO2 from air, producing useful and marketable products, Electrographite and Oxygen, unlike Irish factory for CO2 scrubbing that have costed $350 million, produces chemical that cost and have to be painted to big pannels and after capturing CO2 be scrapped off and disposed into old oil wells), from Financial and unemployment crisis as well. Some more food could be produced in Greenhouses included, too.
I have other inventions like water condensation devices and installations that can be scalled up to provide water on agricultural scale, and this can solve problem of thirst and food production as well.
Unfortunately I cannot find investors for development, and funds that have 5, 50 or 500 millions ad lower limit of investment cannot invest in development since it is too small amount and for bigger they require tested and demonstrable prototypes, all calculations (where standard formulas do not apply to my turbines) and CFD simulations to be able to invest the money.
I live in poor country and collapse of my Business Bank has taken away all my liquid assets and broken back of 4-5 of my biggest clients that have liquidatedcompanies for insolvency and have left unpaid big bills for goods or services received, so I become indebted to my vendors and suppliers, debt which I am still unable to return in spite of big mortgage credit I have taken. After this Banks have raised interest from 9.5% to 12.5% per year, so I survive by miracle only.
Pls, advise me what can I do?
I have what whole world is looking for and nobody can invest money as they did not foresee New technology development financing.

Hi #8:

LOL... I got news for you. If you were a US citizen you still would not be able to reach them unless of course you were worth a whole bunch of millions of dollars....

#&*!? I wrote comment and it say 1 character remained but after submitting it it disapeared completely :-((

Anyhow, I invented true WindSolars capable of working 24/365, having zero Land Footprint at electricity cost under 10 Euro per MWh for 10 MW models. Scalable down but with rising cost of electricity since same but smaller capacity subsystems (steam generator, steam turbine and elkectricity generator) cost unproportionaly more. Could be incorporated into new buildings specialy big ones. Working on or off Grid without need for backup from standard electricity generators. Wind part is optional and depending on presence of at least 5m/sec. wind in economicaly usable quantity or frequently enough.
Unfortunately I cannot reach Mr. T. Boone Pickens (Pickens Plan) nor Mr. Obama since I am not US citizen.
Who is interested to invest money in development may contact me at oberon(at)globalnet.hr

Go figure Kimberly. It sound like a practical approach to me. The only really significant improvement I would make on this system would be to move to the Vertical Axis Wind Turbine Design. They seem to operate better at lower wind speeds and and the design eliminates the need for a pivotal base for the prop design to stay in the wind stream as wind direction shifts.

@Anonymous Comment 5. Unfathomable to my why this hybrid renewable energy system would be considered stupid.

Indeed, we won't need fossil fuels in the same capacity as we use them today. And, utilities will transform from a demand side provider to a support side supplier--where homes and buildings will generate their own electricity and systems like this can be a part of the solution, that is, as soon as we can overcome the storage conundrum. Because fossil fuels have unparalleled energy density, hybrid RE systems will need to play a bigger part of the picture to bring this to a reality. Indeed, renewable energy becoming the norm will either be due to price or unless there is a HUGE shock e.g. financial, natural, etc. Bottom line: hybrid RE systems only make common sense.

If I had an improvement to offer Southwest on its' design it would be to add a pivoting generator platform as they have with the solar tracking system. Not the simplest thing to do; but far from difficult either. Let the genny follow the Wind as the PV module follows the Sun.

Hi:

Skystream has an interesting history. We have a few right around where I live. I call them the wrongway 3.7 because they spend allot of the time pointing 180 degrees away from where they should be pointing. In short, they don't turn into the wind as easily as they should, but they are of course a downwind machine by design.
One of the engineers that used to work for them has a post about the product and them on the Internet. Interesting reading but nothing of surprise really... business over engineering but what else is new....

A Hybrid wind/solar system of 12.5kWh has been offered by a Duluth, MN company for the last 4-5 years. Although the end user would have to add the solar side. That combination may have been the first smaller system on the market.

This system if applied with the new wind generator placement to utilize the wind currents of neighboring wind generators could be quite productive as the production figures vary from some 50 to 70 percent increased production using the correct placements.
