"DO I HAVE A GOOD SITE FOR
WIND POWER?"
Wind powered battery charging systems can be
cost-effective if the average wind speed is nine miles per hour (mph)
or more at the location of the wind generator. If you are using wind
in combination with photovoltaic power, it may be cost effective if
good wind is available only during part of the year. When the wind
speed doubles, the power delivered is eight times as great . Most wind
generators are designed to deliver maximum power at a wind speed of 30
mph. At 15 mph, they will deliver about 1/8 their rated power. A wind
generator should be mounted at least 20 feet higher than any
obstruction within 300 feet to avoid turbulence. The power output of a
wind generator will decrease roughly 3% for every 1000 feet of
elevation. |

Applications
for small wind turbines
|
|
More than 50,000 Southwest Windpower wind turbines are
used on remote homes and cabins around the world. Whether your remote home
is for a weekend get-away or you live there full time, Southwest Windpower
has a wind turbine to match your energy needs. Best of all, our products are
designed to make it simple for the user to site and install.
 Battery-charging system with wind-solar hybrid
Small wind and solar panels (photovoltaic) are often
seen as complimentary technology as both are used together as a hybrid
system to offset the variability of sun and wind resources.
Is a wind turbine right for me?
If you have a wind resource greater than 8mph (4 m/s)
and your area is free from obstacles then a wind generator will likely be a
good match. It is that easy! An important reason to have a wind turbine is
because of the seasonal variations of your solar and wind resources. A
hybrid system that uses both solar photovoltaic panels and a wind turbine
will make the perfect compliment that provides minimal interruptions in
power. Depending on your energy consumption and wind speed, the chart below
will help you decide which turbine best fits your needs.

An all new technology for water pumping: In partnership
with
Grundfos International, the SQ Flex
technology is leading the industry in
 wind/Solar –
electric water pumping. Rather than the traditional mechanical windmill,
wind/solar electric systems can provide water at any time.
Is a Wind//Electric Water Pumping System Right
for You?
Southwest Windpower/Grundfos wind electric water
pumping systems are excellent for replacement of mechanical wind systems or
new installations. The proven reliability of the system along with world
wide service and sales offices make this technology the right choice. There
are a number of models available for various outputs and well (bore hole)
depths.

The complete SQFlex pump range
consists of 7 different pump sizes: 4 centrifugal
and 3 helical rotor pumps. All pumps are fitted with
the same size motor which, together with the new
sizing tools, makes system sizing simple.

CU 200
A user-friendly interface box that maintains two-way communication
with the pump and monitors the operating conditions. Built-in
diagnostics indicate faults and dry-running, display operating
status power consumption and level switch input.
|
|
 |
IO 101
A very simple and easy-to-use system and with cable
interface. Controlled by a manual on/off switch.
IO 101
Acts as interface for powering back-up supplies, providing
automatic change-over. For instance when changing from generator to
solar energy, the solar panels automatically power the system as
soon as the fuel tank runs dry.
|
|
 |
Level Switch
Save energy as you save water. With a level switch inside the
storage tank connected to the CU 200 control unit, the pump knows
when the tank is full and shuts itself off.

200 WIND TURBINE
Produces high voltage DC output to power the SQFlex pump at maximum
efficiency. It can be used in combination with GF43 Solar Module.
Startup wind speed of only 7MPH and peak output of 900W, make the
200 Turbine an excellent choice in a wide variety of locations.
|
|
 |
GF43 SOLAR MODULE
Specifically designed to power the SQFlex system, the GF43 produces
a high DC voltage of 140VDC, reducing losses through cables and
providing peak efficiency for the SQFlex pump. Each GF43 is capable
of producing 43 watts of peak power and is designed to be connected
in parallel with other GF43's. This allows the SQFlex system to be
optimized to your location & water requirements.

Southwest Windpower products are the most widely used wind turbines for
remote telecommunication sites. Whether you need just a few watt-hours per
day or a lot more, we have a prod uct
for your needs. You can save thousands of dollars per year of generator run
time with the installation of just one wind turbine on your site. Best yet,
our Air Industrial can be installed in just a few hours with no additional
tower.
How Can a Small Wind Turbine Help Me?
If your remote site uses a battery bank of any voltage configuration and
is charged by a generator, PV panels or both; and you have a 9 mph (4.5 m/s)
wind resource or better, then a small wind system will work. Using an
existing communications tower, you can install and Air Industrial off the
side using available hardware and connect the turbine directly to your
batteries. It is that simple. Every time the wind blows, it reduces the run
time on your gas generator saving you hundreds or even thousands of dollars
per year in fuel costs. Need something larger? Look at the chart below to
get a sense of which machines we suggest for your application.

Close to 500 oil platforms located in the Gulf of Mexico use both small
wind and photovoltaics panels to provide power for SCADA systems and/or
platform lighting. Because of the product reliability, companies from
Exxon/Mobil to Kerr-McGee exclusively use Southwest Windpower’s small wind
generators for providing power on their offshore platforms. Rather than
consuming oil with thermal electric generators, these companies and others
have found it more cost effective to use renewable energy. Furthermore,
small wind has become a standard on these platforms as it offers greater
system reliability and a reduced photovoltaic footprint on the platform.
This reduces the wind loading on the structure.
Can Small Wind Work for You?
Small wind systems are extremely effective for providing small amounts of
power on platforms even in volatile environments. Special explosion
resistant diversion loads safely dissipate any extra energy not used on the
platform. The AIR-Industrial uses a sealed alternator design that is free
from potential arcing. Furthermore, the turbine’s cast aluminum frame and
powder-coated body make it resistant to the corrosive elements. Larger wind
turbines with higher output are also available. We recommend three different
models depending on your energy needs. For volatile environments, we only
recommend the AIR-Industrial.

Cathodic protection is a method of preventing corrosion
of metal pipes, industrial systems or other infrastructure that is submerged
in water or buried in the earth. Corrosion is prevented by running a
low-voltage electric current to the metal (cathode) that needs protection.
Windpower-charged battery banks perform beautifully in this application.
Wind turbines are used to power cathodic protection
systems for submerged marine platforms, oil and natural gas pipelines, oil
and natural gas wells and tank bottoms throughout the world.

 A rapidly growing
application for small wind is its use on monitoring and signaling sites. The
advancement of technology through satellite communications and lower power
consumption of ground based systems has made monitoring sites practical.
Likewise, small wind technology has also progressed. Today’s small wind
turbines are very low cost, high output, reliable and easy to install. The
United States to the Dutch governments, Greenpeace, NASA, United States
Geological Survey and NOAA are just a few of the organizations that use
thousands of Air and Whisper wind turbines for monitoring sites around the
world.
Can Small Wind Work for You?
Small wind systems are extremely effective for providing small amounts of
power for monitoring sites. Southwest Windpower’s turbines are easy to
transport and install and can be used on a variety of structures. If you
have a wind resource greater than 8 mph (4 m/s) and your area is free from
obstacles then a wind generator will likely be a good match.
An important reason to have a wind turbine in your system is the seasonal
variations of your solar and wind resources. A hybrid system that uses both
solar photovoltaic panels and a wind turbine will make the perfect
compliment that provides minimal interruptions in power. Depending on your
energy consumption and wind speed, the chart below will help you decide
