|What size turbine would I need for my home?
Homes use approximately 9,400 kilowatt-hours (kWh) of electricity per
year (about 780 kWh per month). Depending upon the average wind speed
in the area, a wind turbine rated in the range of 5 to 15 kilowatts would
be required to make a significant contribution to meet this demand
Wind Systems Inc
|Entegrity Wind Systems is a leading
manufacturer of intermediate scale wind turbines with installations
world wide. The EW15, a 50 kilowatt wind turbine generator
is specifically designed to supplement electric power generation
for large buildings, industry, commercial operations, large
farms, communities and remote locations.
The EW15 is an ideal investment to combat rising utility
rates by enabling owners to secure their costs for electrical
energy now against much higher future costs. The EW15 has
a thirty year design life and is very easy to operate and
maintain. Our team of dedicated and experienced engineers
is committed to make the EW15 efficient, reliable and affordable.
As the wind industry continues its rapid evolution, many
technologies that were once state of the art are now classified
as obsolete or difficult and expensive to maintain. We at
EMS leverage our intimate understanding of most all commercial
wind turbine systems deployed in North America, new and
old, as we develop products designed to enhance or replace
these aging technologies and improve asset performancem.
Southwest Windpower has wind turbines to
meet a broad range of needs.The world's leading manufacturer
of battery charging wind turbines for remote homes, sailboats,
recreational vehicles, telecommunications, and hybrid systems
offers a complete line of wind turbines for virtually any
|Westwind is an internationally renowned manufacturer of
high quality and robust 3kW, 5kW, 10kW and 20kW wind turbines.
Westwind have supplied turbines, towers and turbine controllers
for use in many different applications around the world since
Westwind turbines enjoy the reputation as one of the most
heavy duty and robust turbines available. This makes them
the ideal choice for remote area applications where maintenance
is expected to be infrequent and or costly.
The turbines are designed for strength, simplicity, and low
maintenance as the major design criteriaAll Westwind wind
turbines consist of three blades, up wind of the tower on
a horizontal axis and attached directly to a sealed permanent
magnet generator.Rotor over speed protection is achieved via
auto furling. The turbine can also be manually furled at the
base of the tower. Furling describes the action of the tailboom
pivoting around to be at right angles to the axis of rotation.
This action turns the blades out of the wind and thereby reduces
power output.Previous Westwind designs in the 2.5 to 10KW
range utilised pitch weights as an additional control measure.
The new blade profile used in the mk2 machines as well as
being more efficient is mechanically much stiffer. This means
the pitch weights are no longer necessary. They contributed
significantly to the aerodynamic noise of the blades so now
our machines are barely audible
|These well-known wind generators are manufactured here in
the UK by LVM, a company with over 15 years experience making
wind turbines. They have been used all over the world by yachtspersons,
research institutes and by Military Forces.

3.7 - Domestic Scale Wind Turbine
| Skystream 3.7 is the first all-inclusive
wind generator with the controls and inverter built into the
The Skystream 3.7 has been developed by Southwest Windpower
in collaboration with the U.S. Department of Energy’s
National Renewable Energy Laboratory (NREL), and is the
newest generation in residential wind technology.
The Skystream 3.7 is a down-wind (wind hits the blades
on the downwind side of the tower) direct drive (gearless
or no transmission) permanent magnet wind generator. Skystream
3.7 uses an innovative 3.7m rotor and produces approximately
300 kWh per month at a typical UK 5m/s AMWS site.
The initial prototype has been operating at the U.S. Department
of Energy’s National Renewable Energy Laboratory (NREL)
in Colorado for almost two years and has undergone extensive
performance, reliability and duration testing in accordance
with internationally accepted testing standards
|The Swift Wind Turbine was developed
by Renewable Devices in Scotland. This team of engineers had
a passion about providing safe, clean energy for everyone.
The Swift system is the world's first rooftop wind turbine
with unique, patented technologies for unprecedented safe,
efficient, and near silent operation. With installations worldwide,
this design icon has been quietly generating clean energy
for homeowners, community groups, and commercial customers,
for over four years. The emphasis of the Swift design has
been focused on safety, reliability, and ease of operation,
alongside the high-performance of this innovative system.
Unique technologies led to the filing of five international
patents, which allow the Swift Wind Turbine to offer:
Quiet, vibration-free rooftop operation
Safe, efficient and autonomous operation
Visually appealing design
Sustain, harm neutral design - allowing the Swift to become
carbon and energy positive within four years
Zoning - operates below maximum noise levels and eliminates
the pole fall height restrictions
The Swift turbine is mounted on an aluminum mast with a
minimum blade-roof clearance of approximately 2 feet. It
is usually mounted at the highest point of a roof, in a
position which benefits from maximum prevailing wind, but
it will work effectively in almost any location. The Swift
is designed to be both aesthetically pleasing and quiet.
The Swift turbine mounting brackets incorporate a damping
system, specifically designed to absorb a wide range of
frequencies. The patented diffuser minimizes turbine noise
by preventing noises at the blade tip. In addition, the
five bladed design allows for a slower speed of rotation
to further reduce noise, making the Swift Wind Turbine one
of the quietest wind systems. Now you can have a quiet vibration
free energy generated right from your rooftop.
|Marlec manufacture small battery charging wind turbine generators
The Rutland 503
Rating: 25 W in a 22 mph (10 m/s) wind
Voltage: 12 Volts DC
Rotor Diameter: 0.51
Cut In Windspeed: 6.6 mph (3.0 m/s)
This compact wind generator, is ideal for use on yachts
or touring caravans etc, where ease of installation, a light
weight and size are important considerations.
With a turning radius of 255mm and a unique outer ring
around the blade tips it can safely be installed on a confined
boat deck. The machine is centrally supported so performance
is unaffected by a pitching sea. Stainless steel fasteners
and marine grade materials are used throughout.
It starts charging in 6.6mph (3.0 m/s) winds and will give
a maximum output of over 60 W.
It is designed to mount onto 1.25" (31.7mm) internal
diameter aluminium tube and an adaptor is available for
permanent land based installations using taller towers
