Windspire: Vertical Axis Wind Turbines



Affordable, attractive, and ultra quiet, the Windspire® wind turbine gives you the power to create clean energy from the natural wind just outside your door. At only 30 feet tall and 4 feet wide, the Windspire 1.2 kW wind turbine is distinguished by its sleek propeller-free design and ultra quiet operation. Designed for use where you live and work, the Windspire is currently powering homes, small businesses, schools, museums, parks, and much more.

Power from Wind
The Windspire® wind turbine generates power when wind blows against its vertical airfoils causing them to spin. This power is then converted to AC electricity and is immediately available to power your home grid and all the appliances that draw electricity from it, such as lights, refrigerators, and air conditioners. While the technology behind the Windspire is complex, the basic premise is simple: the stronger the wind the more power it will generate.

Advanced Technology
The Windspire® wind turbine was designed from the ground up as a complete system, both to maximize electrical and mechanical efficiency, and to minimize the system cost for our customers. The patented technology includes a high-efficiency generator, integrated inverter, hinged monopole, and wireless performance monitor. The 1.2 kW (1.2 kilowatt or 1200 watts) Windspire will produce approximately 2000 kilowatt hours (kWh) per year in 12 mph average winds. The Windspire also includes WindSync wireless monitoring software so you can check your power production in real time.

Affordable
In the US, a complete Windspire 1.2 kW wind turbine typically costs between $9,000 and $12,000, fully installed. After rebates, the costs can be as low as $3,800, which is much lower than comparable wind turbines and other alternative energy options. The price includes the poles, inverter, wireless performance monitor, and the hinged monopole, so there are no expensive extras to buy. A 30% federal tax credit (available in the USA) and local rebates are available in some areas. The average payback is under 10 years.

High Quality
Rugged yet simple construction means durability and low maintenance for customers. The Windspire® wind turbine is designed to operate for 20 years or more. It is made with durable, corrosion-protected steel and aircraft grade aluminum construction, quality oversized bearings and a very simple mechanical structure, and rated to withstand high winds (up to 105 mph), snow and ice. The Windspire is made in the USA (Michigan), with extensive quality control measures in place to ensure customers receive a quality product.

Clean Energy
The Windspire® wind turbine generates energy from a clean, natural, and inexhaustable source, replacing power currently being produced by pollution-emitting coal fired plants and other sources. Choosing a Windspire is a wonderful opportunity to make a statement about your commitment to protect the Earth.

Wind and Site Requirements
The Windspire® wind turbine was designed to operate in areas with average wind speeds of at least 10 mph (4.5 m/s), although it works best where average winds exceed 12 mph (5.4 m/s). Winds vary by location, even within a property, and generally preferred sites are clear of nearby obstructions such as tall trees and buildings. Your Windspire dealer can discuss siting guidelines with you in more detail.
