Mariah Power 1.2kW Wind Power System - WINDSPIRE
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.
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.
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.
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.
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.

Wind turbines capture the power in the wind and turn it into electricity. A complete wind turbine system such as the Windspire® includes four basic components, although many systems are limited to just a rotor and generator.
- Rotor The rotor catches the wind (is pushed by the wind), and converts the energy of moving air into rotational mechanical energy.
- Generator The generator converts the mechanical energy into electricity by rotating a magnetic field over electric coils, producing an electric current.
- Inverter The inverter takes the DC electricity produced by the generator and converts it into a usable AC form.
- Structure The structure provides strength, height, and supports the rotor.
The Windspire vertical wind turbine is the result of extensive engineering development work, and boasts many unique features that set it apart in the marketplace. One of the distinguishing features of the Windspire vertical wind turbine is that it was engineered as a complete system. It includes more than a rotor that turns in the wind and a generator to generate power. It also includes an integrated inverter, the complete pole and structure, and a wireless monitoring system. The advantage of designing the Windspire from the ground up is that we were able to optimize each component to work together for maximum system efficiency at the lowest possible cost, a benefit we are proud to pass on to our customers.

Installation is Quick and Easy
Simple to install, the Windspire kit ships with everything you should need except the concrete itself. The complete system in a box includes: structure, electronics, and rotor. Once your 2x 6 concrete foundation is poured and set, your Windspire Dealer can install your new Windspire in as few as three hours without the use of heavy machinery. The Windspire is a simple plug 'n produce system - it is ready to generate electricity as soon as it is connected to the grid.
Maintenance is Minimal
With moving parts designed for a 20-year life, and bearings that are greased for life, there is no scheduled maintenance. However, we do recommend that owners perform a visual inspection of their Windspire annually and check bolts for tightness. Should you have any concerns, please report them to your dealer immediately for quick resolution.
