Quick Answer
An average small wind turbine can produce between 2 and 20 kilowatts (kW) of electricity, with most residential installations falling in the range of 2 to 10 kW. This production level is sufficient to power a single-family home and some small businesses.
Wind Turbine Energy Production Basics
Small wind turbines are designed to capture wind energy and convert it into electricity. Their energy production is influenced by factors such as wind speed, turbine efficiency, and hub height. A typical small wind turbine has a hub height of 30 to 50 meters (100 to 164 feet), which allows it to capture wind at higher elevations and produce more electricity.
Common Small Wind Turbine Specifications
Some common small wind turbine specifications include:
- The XZ-2000, a 2 kW turbine with a 3-meter (10-foot) rotor diameter and a hub height of 30 meters (100 feet), produces 3,600 to 6,400 kilowatt-hours (kWh) per year in moderate wind conditions.
- The Bergey XL.1, a 2.3 kW turbine with a 1.8-meter (6-foot) rotor diameter and a hub height of 34 meters (112 feet), produces 3,500 to 5,500 kWh per year in moderate wind conditions.
- The Southwest Windpower Skystream, a 2.4 kW turbine with a 1.8-meter (6-foot) rotor diameter and a hub height of 25 meters (82 feet), produces 3,000 to 5,000 kWh per year in moderate wind conditions.
Evaluating Small Wind Turbine Energy Production
When evaluating small wind turbine energy production, it’s essential to consider factors such as wind speed, turbine efficiency, and annual energy production (AEP). AEP is typically calculated using a wind speed distribution curve, taking into account the expected wind speeds at the installation site. This allows homeowners and businesses to estimate the expected energy production and make informed decisions about small wind turbine installations.
