As the fastest growing energy source in
the world, wind energy is now a popular choice for electricity.
In areas with sufficient wind, wind power provides the most economical
source of green energy. ETA sells turbines by Southwest Windpower,
the world leader in small wind turbine manufacturing, sales,
and exports. With their advanced and innovative design, they offer the
highest power output, the lowest amount
of noise, and the most affordable
prices on the market. These systems create no waste or pollution,
and since the energy comes from the wind, there is never
a need to refuel. In addition, their new design also makes
them very quiet. Why use a noisy, polluting generator
that constantly needs to be refueled? As
conventional energy costs continue to increase, so do your savings.
This is a long term investment that can increase the value of your
property.

The next generation AIR-X!
Southwest Windpower is pleased to introduce the latest in small
wind turbines, the AIR-X. The AIR-X
wind power generator builds upon what has made AIR the world's
#1 selling small wind turbine with technology previously found only
in today's mega-watt class wind turbines.
Much Lower Noise: Previous AIR wind generators
relied on their aero-elastic blade design for protection in high
winds, causing loud flutter noise in winds above 35 mph (16 m/s).
AIR-X’s circuit monitors the wind speed and electronically
slows the blades as it reaches rated output, preventing it from
going into flutter. This results in a much quieter wind turbine.
In high winds, the AIR-X will continue to produce power at a reduced
level until the wind decreases, then maximum output will resume.
Improved battery
charging: Previous wind generator designs
required 300-400 amp hour battery banks so the trickle charge of
the wind turbine could be adequately absorbed. The charge controller
periodically stops charging, reads the battery voltage, compares
it to the voltage setting and if the battery is charged, it completely
shuts off all current going to the battery. This function is performed
within a few milliseconds. The closer the battery is to its full
state of charge, the more often the circuit repeats this action.
This means any size battery bank from 25 to 25,000 amp hours or
higher can be charged safely. When the battery has reached
full charge, the blades will slow to an almost complete stop. Only
when the battery drops below its voltage set point will it resume
charging.
Lower stress
design: Power is limited on the input side of
the electronics by controlling the torque from the blades. The excess
energy no longer has to be dissipated by the electronics resulting
in lower stress on the circuit, bearings and other materials.
Stress occurs primarily in high winds, but under these conditions,
the electronic stall design reduces the blade speed to 600 rpm,
significantly reducing mechanical loading while producing power.
Note: A manual
stop switch control is an available option.
