Wind Turbine for Homes: Everything You Should Know

Wind energy has been used for generations for its mechanical power in water pumps, grain grinders, spice processing, and more. Nowadays, wind turbines are used to harness kinetic energy from the wind to transform into electrical power by using the same technology as large wind turbines.

The use of wind energy is becoming more popular in the renewable energy industry. With a small wind electric system, US homeowners can partially or fully offset monthly electricity bills or even live off-grid.

If you want to learn about wind power, this article is for you. Here, you will learn what a wind turbine is, its power output for residential purposes, as well as the cost of wind turbines. We even compiled a top 10 of the best residential wind turbines available. For those looking to know more about solar vs. wind energy, we added a very interesting section comparing both technologies. 

What Is a Home Wind Turbine?

Residential wind power is generated by transforming kinetic energy from the wind into electricity by using a residential wind turbine installed above 6 meters (20 feet) to fully take advantage of prevailing winds. These turbines use the same principle as large wind turbines installed at large wind farms worldwide.

The first step for a wind power generator for home and work lies in its blade. Turbine blades have a shape making air pressure flow unevenly on both sides, which in turn makes the blade rotate at a certain speed proportional to the speed of the wind. These blades make the rotor of the turbine rotate at a certain speed expressed in revolutions per minute (RPM). While RPM of most rotors is not enough to generate electricity, this is no problem for a residential wind generator.

To increase the speed efficiency of wind turbines for wind power generation, the turbines have an inner gear that increases the RPM perceived by the rotator, allowing the turbine to fully convert the kinetic energy of the wind into DC energy.

Wind turbines for homes are connected to an MPPT charge controller that manages energy flow from the turbine to the battery bank and to the inverter which converts DC into AC energy to power appliances.

Important Terms to Know About Wind Speed

When choosing a home wind turbine from the top 10 models on the list, there are some terms that you should know beforehand to understand the specifications for each model.

  • Cut-in speed – Wind speed at which the generator starts producing wind power
  • Rated wind speed – Optimal tested speed for the generator to produce its installed capacity
  • Survival wind speed – Maximum wind speed that a wind turbine should withstand for safety precautions

Can a Wind Turbine Power a House?

Residential wind turbine systems can partially offset an electric bill or cover the load consumption for the home depending on its size. To know if a wind turbine can power a house, you must first know how much energy a wind turbine produces and compare this to the household power consumption.

The average US home consumes on average 10,649 kWh annually, 877 kWh monthly, or up to 29.23 kWh daily. In the top 10 small wind turbines for homes, you will find models with different shapes, sizes, and generation capacities that can range between 200 and 2000 Wh when exposed to rated wind speeds of 10.5–20 m/s (23.48–44.73 mph). While these residential wind turbines can partially offset an electricity bill, to fully offset the 877 kWh average monthly consumption and live off-grid, you should install a system comprising several wind turbines for your home.

When installing a wind turbine system, you should also consider the capacity factor for residential wind turbines in the USA, which is a parameter defining the real annual energy output for these wind turbines in relation to their capacity.  

Considering the US average capacity factor of 16–20% on land, a residential wind turbine system with an installed capacity of 7,700–6,100 W can cover the annual average power consumption of 10,649 kWh.

How Much Does a Wind Turbine Cost?

If you are interested in the benefits of wind energy for your home, you might already be wondering how much a wind turbine costs.

The residential wind turbine cost varies considering manufacturer, quality of the turbine, and several other factors, but the main factor is the power capacity. The cost of a wind turbine with a small capacity of 200 W costs approximately $250–300, a mid-capacity 1,000W residential wind turbine costs around $1,000–1,200, and a 2,000W high capacity residential windmill costs around $2,000.

When considering a budget, you should factor in major components like the DC/AC power inverter and the wind turbine tower. You should also consider prices for minor components like wiring and permits,  since they make up part of the cost of wind energy systems.

Clean energy enthusiasts interested in wind energy with a low budget or those wanting to test a wind turbine can learn how to build a wind turbine for home use by following this DIY residential wind turbine project. After you build your own wind turbine and test that the technology and output are satisfactory, you can get the real deal to power your home.

What Is the Difference Between Solar Energy and Wind Energy for Your Home?

Solar and wind energy are becoming the main renewable energy sources for US citizens. Here, we compare both technologies by analyzing how much wind turbines are efficient in comparison to solar panels, what the best technology is , and how well they work when combined.

Wind Energy vs. Solar Energy: Which One Is More Efficient?

The main difference between solar and wind energy is that solar power is generated using solar panels that convert solar radiation into electricity during sunlight hours, while wind power uses wind turbines to harness kinetic energy from strong winds throughout the whole day.

Considering the average capacity factor for wind energy in the USA, a small wind turbine for home generates 16–20% of its capacity annually. To estimate how much energy a wind turbine produces at your home, you can install a recording anemometer at 6 meters (20 feet) comparing wind speed against the performance curve of the wind turbine.

Solar panels rely on the solar irradiance for each state. Most panels have a capacity factor of 10–25%, and they have a daily energy output equivalent to 4–6 hours at full-capacity generation depending on the solar radiation index for each state.

Considering annual power output for wind and solar power, the efficiency is relatively similar for both technologies. The main difference lies in the overall time that the equipment is generating power and the relation of wind speeds vs. solar irradiance by state. Some states have faster winds making wind turbines a wise choice,  while others have great solar irradiance making them perfect for solar panels. Only a few are ideal for both residential solar and wind power systems.

Efficient Use of Space

Solar panels only require rooftop space at houses. Portable solar panels on RVs can use both the rooftop and surrounding areas of the vehicle. Wind turbines, on the other hand, require land space to install a wind tower tall enough to take advantage of prevailing winds, making it only suitable for homes with big yards and local permits allowing these towers at the ideal height of 6 meters (20 feet).

Comparing Wind vs. Solar Energy

There are some key aspects of each technology that are worth comparing as can be seen below.

Wind energySolar energy
Can generate power day and nightCan only generate power during sunlight hours
Generates electricity even on cloudy daysReduced efficiency with clouds or shades
Requires regular maintenanceRequires low maintenance
Requires additional land space for the installationOnly requires rooftop space
Local legislation in some states prohibits installing wind towers at the right heightPractically every state allows installations of solar panels on rooftops
Turbines generate 16–20% of their capacity throughout the dayPanels generate their full capacity with 4–6 peak sun hours of during the day
Prices have fallen 23% in the last 10 yearsPrices have fallen 73% in the last 10 years

Is It Possible to Combine Both Solar and Wind Power?

Homeowners in states with great wind speeds and peak sun hours (equivalent number of hours in a day where the solar panels generate to their maximum capacity) can opt to install hybrid generator systems combining both wind and solar technologies. Hybrid generators are installed by solar wind companies specializing in the installation and integration of solar panels and windmill generators for homes.

Solar wind technology can be efficient and cheap, especially since some major components for both systems can be shared like the lithium, flooded or AGM battery bank, DC/AC inverter, and others. A hybrid generator system can be especially useful for off-grid homes, since solar panels can produce solar power at times with slow wind speeds during daylight hours and wind turbines can generate electricity at night or on cloudy days.

Battery Bank for Hybrid Systems

Since solar and wind generation systems require energy storage systems, so do hybrid systems. These combined solar and wind systems store excess energy in a battery bank to be used later when electricity generation is not high due to weather conditions.

While it might be tempting to install a motorcycle battery or a golf cart battery due to low prices and high capacities, these are not suitable options for residential solar and wind power systems. Residential energy storage systems require a wet cell battery or solar battery bank, since these are deep-cycle batteries operating at 12–24 volts, ideal for these systems.

Is a Home Wind Turbine Right for Me?

Before investing in a home wind turbine, it is important to consider certain aspects to know if you will be able to fully take advantage of wind power generation. Here, we will explain the most important things to consider before installing a wind turbine.

Are You Allowed to Install a Wind Turbine Where You Live?

While most states allow for residential wind turbine installations, some have laws restricting aspects involved in this installation. For instance, the ideal height to install a wind turbine is just above 6 meters (20 ft.). Since most locations have a 35 ft. height construction limit, this might not be a problem.

Noise levels can be another restriction. Check the dB that the turbine makes when operating, and verify if they would be allowed in your neighborhood.

Investigate the Wind Resources at Your State

To fully take advantage of wind energy, you should have good wind speeds in your state that go from 10.5 to 14 m/s (5.6–31.31 mph). These wind speeds will ensure that most turbines installed at your home can fully generate their power capacity. Installing an anemometer at your location will allow you to measure wind speeds to later compare this data with the performance curve of the wind turbines on the list.

Do the Math and Make the Right Call

Finally, you should compare the available information for your state with the specifications for your desired wind turbine from the top 10 turbines on the list and make a choice.

For instance, let us calculate the power output for the 2,000 W 11 Blade Missouri General Wind Turbine considering a 20% capacity factor. Using the formula below, we can estimate an average production.

As can be seen above, the turbine would generate around 2,803.2 kWh annually, easily offsetting around 26% of the electricity bill for the yearly average national consumption of 10,649 kWh.

To fully live off-grid with this consumption, you need a higher capacity system combining 3–6 of these turbines in a small wind-generation system. When considering every aspect of the costs, you should also consider wind energy financial incentives, as well as the tax exemptions and loans in your state.

Conclusion

Wind energy is one of the main options to generate power partially or fully offsetting electricity bills, even allowing you to live off-grid. Installing a residential wind turbine will allow you to generate clean, renewable energy and enjoy the financial incentives and revenues from it.

Considering the high efficiency of wind turbines and solar panels nowadays, it is clear why homeowners are going green with a hybrid solar-wind system. You can also start enjoying the benefits of renewable energy by picking a wind turbine from the top 10 list and powering your home with wind energy.
