What Makes a Wind Turbine a VAWT?
When we think of traditional wind turbines, most likely, we imagine Horizontal Axis Wind Turbines (HAWT) that are commonly quite large with three blades and are used to generate energy on a large scale. In this article, we are examining a different type of turbine that is smaller, has blades that are arranged vertically around a center axis, and is the preferred choice for homeowners looking to make a positive change in their energy consumption
Features of a House Vertical Axis Wind Turbine
Many design features make a VAWT very low maintenance, hands-off renewable power source. Now that we have some choices to choose from, let’s take a closer look at what makes a great VAWT and why this type of turbine is suitable for the residential sector. We will also see some drawbacks and limitations of this type of turbine.
Pros of a VAWT
There are many reasons that these are the choice of residential homeowners all over the country. Let’s see the pros of these turbines.
One of the great features of a VAWT is its ability to pick up wind from any direction. There is no need to recalibrate these little turbines depending on the wind’s direction on a certain day. They typically can begin to operate at slow wind speeds, and no matter where these winds are coming from, they will get your VAWT to start spinning.
Compared to the large scale HAWT, this is a great advantage. There is no need to research how the wind blows and assemble your turbine based on this research type. This is necessary with the industrial horizontal designs, and by eliminating this requirement in the residential vertical turbine, they become much more accessible to the average homeowner.
The upkeep of your VAWT will also be quite easy. After what is usually a very easy installation, many companies are confident that their turbines should have a long, healthy life of around 20 years. Many come with 1-2 warranties for anything immediately wrong, but as long as there are no defects, you should collect energy for a long time after purchase.
These turbines should require very little maintenance, and most are made to withstand high winds and rough weather.
Quiet Operation and Small Profile
No matter if you are way out in the country or have some neighbors close by, most VAWTs are small and operate quietly. Most brands advertise less than 45 decibels of sound, so they will not cause a disturbance to you or those around you. Unlike the industrial-sized HAWTs, you will not have to worry about special permits and permissions to install these on your property.
Their smaller scale and proximity to the ground makes them less obvious, and less of an eye-sore than the larger scale turbines can be seen as being.
Another pro of a VAWT is that it does not pose the same problem to birds as the larger-scale HAWTs have shown to cause. Birds will not be put in an increased danger by installing a vertical turbine on your property. The bright color of many of these models will make it easily visible for humans and animals alike.
Of course, like all sustainable energy options, the truly beautiful thing about vertical wind turbines is that they harness a never-ending natural resource without producing harmful side effects. There is no harm in setting up a VAWT, taking advantage of sustainable energy options, and reducing your carbon footprint.
Cons of a Vertical Axis WindMill (VAWT) or Wind Turbine
However, these turbines are really good at what they are designed for, but not much more. Let’s see their cons below.
Supplemental Energy Only
They do a wonderful job creating an alternate energy source for a residential setting, but it would be challenging to use these turbines as your sole source of energy. They are a great supplement to a primary source, but they are typically unable to require the power you would need to meet all of your daily requirements.
Their small and sleek design is quite advantageous for many homeowners, but it also means they are not high enough off the ground to take advantage of the strong winds blowing above. Since the winds closer to the ground typically have obstacles such as other buildings and structures, they are not usually as strong as winds higher off the ground. Their low-to-the-ground build is a great accessibility feature but does mean they are not as powerful.
Vertical Wind Turbine Design Basics: Darrieus vs. Savonius
Historically, there have been two lasting inventions in terms of vertical axis turbine design. In the 1920s, the Darrieus model came from a French engineer of the same name, while the Savonius model came from Finland. Each of these models has a distinctive design that can be spotted in many of the models we have already seen so far.
Darrieus Wind Turbines
The Darrieus Model originally features curved blades that form the outline of a teardrop shape. In the beginning, these were typically built to be symmetrical, but through the design’s evolution, these external aerofoil blades can be seen in a variety of configurations. Through this evolution, they often resemble a metal kitchen “eggbeater” and have been referred to as the “eggbeater” turbine because of this appearance.
Nowadays, it is not so common to see a design that is purely Darrieus in nature. One main reason for this is that it is hard for them to get started independently without an outside power source. They need a bit of a push to get going before using the natural force of the wind.
Savonius Wind Turbines
The Savonius model looks as if you had a plastic barrel that you sliced in half down the middle. These two halves create a two-scoop design to catch the wind and force an energy-producing rotation. It is also possible to see Savonius models with a three-scoop model with what appears to be three-barrel halves working together to catch the wind.
The downside of the Savonius model is that since it is generally bulkier, it cannot rotate as quickly and efficiently. It is sturdy and stable but not as nimble as the Darrieus.
A lot of time and development has passed since the invention of both of these designs. Nowadays, it is quite common to see hybrid constructions that feature both Darrieus and Savonius blades on the same model. There may be an even amount of each blade, or perhaps one type of blade will be dominant. For example, we saw designs above with 6 of each blade and designs with 6 Darrieus and 12 Savonius on the same turbine.
By combining the nimble rotational ability of the Darrieus with Savonius’s ability to trap wind, vertical axis turbines are continuing to improve and become a more effective alternative energy source. These vertical axis windmills are our way to conserve energy. Do let us know which vertical axis windmill you prefere.
Do remember that Vertical Axis Wind turbines are also known as Vertical Axis Windmills. So when you see us referring to Windmills, do get confused.

Voltage vs. Wattage: What You Need to Know
You may have noticed the different levels of both watts and volts as we have examined different turbine models. Often models boast a 12 or 24-volt generator or a 1000 watt (1KW) output. What exactly do these numbers represent, and how should they impact your purchasing decision?
Watts: Measuring the Output of Power
A watt is a unit of power used here to measure the output of energy collected from the wind turbine. When discussing this on a smaller scale, you will probably be thinking in watts, but for annual usage or industrial usage, it is far more common to discuss this energy in terms of kilowatts. We have seen models with a wide range of possible wattage, from 200 watts in a small model to 3 kilowatts in the most powerful model.
Typically, as the wind speed increases, the possible wattage increases as well. If the wind slows, the wattage will drop as well. When there is a number of kilowatts listed in the name of the wind turbine, that is an indication of its maximum amount of output. However, it is important to note that this number is a best-case scenario. Choose the right wattage vertical windmill for your home
If the model you choose is capable of a kilowatt of power, it will only produce that under optimal conditions. The ability to produce power is dependent on the strength of the wind and the efficiency of the design itself.
Voltage: The Generator’s Capacities
When discussing the voltage of a wind turbine, this is specifically referring to the power of its electric generator. The turbine size will correlate to the amount of voltage required, meaning that a small VAWT will have lower voltages than a large, industrial HAWT.
As the blade turns, this gets a generator moving inside of the turbine. The power of this generator will be measured in volts. A small VAWT wind mill model will typically feature a 12 or 24-volt generator.

DIY Option: Build Your Own Vertical Axis Wind Mill
Using an old hoverboard motor, supplies you can acquire at your local hardware store, and a DIY spirit, it is possible to build your own turbine at home. To see the DIY King build this himself and give his thoughts, you can check out his video here:
In the video, you can see him use a permanent magnet brushless outrunner motor that he could take from an old hoverboard as the base for his VAWT. With some PVC pipes, he can cut them lengthwise to create the Savonius style blades to catch the wind. With some metal tubing, he can create the arms that will hold each of the blades. Altogether, he can construct a fully functional VAWT at home.
One note on this DIY option is best if you can complete this project with someone who has basic engineering knowledge. Schematics are provided in the video’s comments, but it is still a bit advanced for the average person. It will also require some saws and drills that may or may not be a part of your tool kit.
Why Is It Important to Utilize Natural Energy Sources?
It can be hard to make the initial investment when it comes to renewable energy. After reviewing the options here, perhaps you wonder if it is worth it to put your money towards one of these options.
There are two things to remember when thinking about investing in alternative energy. The first is a financial prospect. By spending money now, you are creating your own energy source that will be free for you to use for a long time into the future. This means decreasing the current amount of money you are spending on your energy consumption.
After some time, the wind turbine price will end up paying for itself with the amount of money you can save from the power companies. As you learn more about your properties and wind turbines, you will be able to continue to make improvements and maximize your ability to harness your own energy.
The next reason is not necessarily financial but certainly could have financial impacts on the future. This reason is environmental, creating energy in a way that does not harm the environment. Wind energy is a renewable energy source, meaning that it taps into the limitless supply of wind naturally occurring on our planet, turns it into usable energy, and does not create the fossil fuels associated with other types of energy production.
By doing what you can to lessen the demand for fossil fuel produced energy, you are doing your part to contribute to a more sustainable future for the planet.
Purchasing a vertical axis wind turbine is a wonderful step in the direction of a more sustainable future for your own energy consumption. You can use these turbines to supplement your current source of energy and a way to get a bit of charge when you are in harder to reach places.
When it comes to which model to choose, MAKEMU is a recognized producer in the world of VAWT and provides a variety of choices for many types of consumers. If you are looking for something more simple and affordable, the nylon fiber models like the Pikasola or Kisstaker would be a great place to start.
Whichever you choose, you will be contributing to a more sustainable future and doing your part to lessen harmful impacts on the planet that come from our need for energy.
