Windspire Wind Turbine

At wind speeds greater than 8 mph, the Windspire wind turbine will begin producing power, which is measured in Watts (W) or kilowatts (kW). Power output jumps up and down as quickly as the wind changes speed, so the industry measures output over time in kilowatt-hours (kWh) which is how many watts of power are consumed over a full hour.

Your electric company charges you for energy usage based on a rate/kWh. Over the course of a year,the 1.2kW Windspire will produce approximately2000 kWh in 12 mph average winds to help o-set the energy you require from the electric company. This is approximately one-quarter of the energy usage of an average home.

The Federal Government provides a 30 percent tax credit for the total cost of the unit, including installation. Many state and local municipalities also o-er rebates, as do local power companies.

The Windspire wind turbine rotates at a lower speed than most wind turbines and is more visible to young birds. So far, we have had no reports of collisions – and we have had one report of a nest built under an active unit.

A Windspire site requires land with unobstructed wind and adequate space for installation. The Windspire also needs at least class two winds – ideally class three (an average of 12 mph) – and a tie to the power grid.

The currently available Windspire is grid-tie, which requires the unit to be tied into the local utility grid.

Some utilities o-er net metering agreements that allow credit for, or in a few places the sale of excess power back to the grid using feed-in tarrifs.

The Windspire is independently tested at Windward Engineering in Spanish Forks,Utah. This testing allows customers to know what level of power production toexpect from specific wind ranges. The Windspire Inverter received ETL certification as of March 2008 to U.S. and Canadian standards.

The Windspire requires no scheduled maintenance, with moving parts designed for a 20+ year life and ball bearings that are greased for life. Durable construction enables it to produce power for 20+ years. A dual-layer paint coat, rust proof spray, and zinc plating are applied for weather protection.
