Answered Questions
How
does wind work?
Wind
turbines are ideal for on-site energy generation and can be installed
effectively in most locations. Wind turns the blades, spinning the
shaft to generate power. The electricity goes into an inverter to
convert DC to AC power, then is fed into batteries or the grid to spin
the meter backwards.
Charge Controller included?

Installs in minutes and protects both your wind turbine and battery bank. Easily fits beside your batteries ensuring quiet, safe operation of your wind system.
Do
I have enough wind?
While
these turbine will produce at 7.5 MPH winds, choosing a site with at
least 9-10 mph average wind is advised to make installing a wind
turbine really worthwhile. Below is a map showing the wind in the US.
Consult local records, the weather station, or a wind expert for
verification. The actual wind speed at your site will be influenced by
the local topography and any nearby obstructions such as trees or other
buildings.
What
size turbine do I need?
These
turbines solution can take care of your entire energy supply, or reduce
your energy costs by providing a portion of the total energy. Multiple
wind towers can be connected for combined power generation. An average
US house uses 40 kilowatt hours (kWh) of electricity per day. Keep in
mind this can be significantly reduced with some conservation awareness
and a few efficiency measures. It always makes sense to see where you
can cut or improve electricity use before sizing a power system - many
are surprised to find how a few small changes add up to big savings.
Add up your appliances used to determine the total needs. Here is an
example of how electricity is used in a typical 4-person household.

What
is the environmental impact?
Wind
power is clean power production. It creates zero green house gasses,
addressing climate change. Reduces the use of coal for electricity,
keeping toxic chemicals out of the air and water. Wind is also
renewable - the wind keeps blowing, whereas oil is depleting and causes
global conflicts. Unlike coal mining or drilling, the environment is
unharmed and still usable for farming.
How
tall is the wind tower?
A tower
must be chosen to mount the turbine. In general the higher the tower
the higher the sustained wind speed and the more power generated.
Turbine should be installed as far as possible from buildings or trees
which may block the wind s full potential. Install your turbine at
least 20 feet (6 m) above any surrounding trees or structures, ideally
in a wide open space of 250 foot (76 m) radius. If you live in an
agricultural area where crop dusting is common, or the site is close to
an airport, review regulations for air traffic notification. Your
Whisper will not likely need FAA lights as long as its total tower
height is under 200 feet.
One
thing to keep in mind is that taller towers may not be allowed in some
areas. The tower kit available above provides everything but a schedule
40 pole and earth anchors, which are available at local hardware
stores. Guyed towers are also a good choice as they can be hinged at
the base, making it easier to lower to the ground for repairs and
maintenance, or to avoid damage during extremely hazardous weather.
Installation?
Installation
is simple and straightforward with included guide. Professional
installation services also available by Contacting OM.
Do
I need planning permission?
Wind
energy installations may require some type of permission - it depends
on where the site is. It is a good idea to do some research and seek
approval from your local office. It is also courteous to discuss your
plans with neighbors, and the community group if there is one.
If you
need a permit, prepare the required paperwork and submit your permit
application along with payment covering the filing fee. If a particular
fee seems excessive or inappropriate for your situation, find out the
basis for the fee. You may be able to avoid it or have it reduced.
Contact the building permit agent in your town or county planning
department to obtain any required forms to be filled out. Typical
permitting procedures may include public hearings and zoning meetings,
environmental review, drawing reviews, and fees. Typical elements
looked at may include: minimum parcel size, allowable tower height,
setbacks from property line, sound level limits, building code and
electric code compliance. Download Whisper Wind Installation.pdf for
helpful information relating to these requirements.
As an
early adopter of wind generation in your community, you are playing an
important role for the future of energy and the environment. Your
leadership and efforts to navigate through your local process will help
pave the way for others to follow. Prepare detailed engineered site
layout map and electrical drawings to show placement of your equipment.
If it is unduly difficult to set this up, consider presenting this to
your governing body and requesting change. Help to pave the way for
people going green - this model zoning ordinance is a good place to
start!
Are
wind turbines noisy?
The
sound of the wind blowing usually makes more noise than a wind turbine
turning. While these units will create some sound, it is not likely to
be heard 100 feet from the unit.
Will
wind turbines affect birds?
Careful
monitoring by independent experts shows that birds are highly unlikely
to be damaged by the moving blades of wind turbines of this size. Plus
birds are typically smart enough not to fly into things they can see,
and experience shows as much with these wind turbines.
What
about lightning?
Lightning
is a powerful force of nature, so precautions should be considered when
installing a wind tower. Thankfully lightning protection is a well
known practice and can be applied to wind turbine systems. It is very
important to ground the battery bank, and ground the tower by
connecting the negative wire to a ground rod. These cane found
pre-assembled, or made out of galvanized steel pipe or an iron rod.
They are buried underground close to the batteries or tower.
While
these measures are well known and effective, Mother Nature may still
find a way. All things considered these arrestors are worth affording
for the safety and protection they provide to highly engineered
equipment.
Can
I use wind power for heating?
Yes,
however the energy required to heat a building is usually significantly
more than the energy used in electricity, so a much larger turbine
and/or battery system would be required. The same may go for water
heating. Consider solar heating and solar hot water and employ energy
efficiency measures to reduce use or waste.
Can
I connect my turbine to the grid?
Yes,
utility connected installations are possible with these systems. When
wind energy is produced your home will use it first, and if more is
needed it will seamlessly draw from the grid. No need for batteries in
this type of setup. Different connection standards are in place for
different utility providers, some requiring an onsite inspection once
the installation is complete. Contact your utility and ask for an
interconnection agreement. US Federal law supports the development of
wind energy systems, as the Public Utility Regulatory Polices Act
(PURPA, 1978) requires utilities to connect to wind providers. The
Whisper is UL approved (Underwriter Laboratory) and complies with all
anti-islanding laws that require the system to shut down in the event
that the electric grid shuts down.
Can
I sell electricity back to the grid?
In times
of high wind production and/or low energy usage, your electricity meter
will actually spin backwards. This energy can be used when there is
less wind or use exceeds production. In some places where net metering
is in effect, utility companies are obligated to purchase the excess
power from you or give you a credit for it. Check your local laws to
determine how this works for your wind project. You may also need to
install an export meter before you are able to keep track of and sell
energy back to the grid.
How
much of the time does the wind turbine produce electricity?
This
unit generates electricity 70-85% of the time. The amount of energy
generated is dependent on wind speed.
What
happens when the wind stops blowing?
Your
electricity continues uninterrupted by coming from either your battery
supply or from being connected to the grid.
How
long do these wind turbines last?
Around
20-30 years, with high performance reliable parts that are built to go
the distance. Southwest Windpower has produced over 90,000 turbines
over the past 20 years, servicing customers large and small in 90
countries around the world. A lot of time has been invested to make
this a superb wind solution. A 5-year warranty backs it up.
