We develop, manufacture and install small wind turbines of 2, 10 and 50 kw for farms, rural households and businesses.
We are happy to introduce You to our available products: 10 kW small wind turbines. We are also working on a number of new turbines (2 kW and 50 kW), and You can find their preliminary descriptions below.
TUGE10 is a class II horizontal axis small wind turbine for households and businesses. It is a 10 kW wind turbine with a 82 m2 rotor area and a 18 or 22 m hydraulic tilt-up tower. This is an upgraded, second generation version of our original 10 kW wind turbine.
The main benefits of TUGE10 are:
Great return-on-investment due to favorable price
Easy and low-cost maintenance every 2 years
MCS certification in progress
Low rotation speed and low noise
Fail-safe tip brake and spring-applied electromagnetic rotor brake
TUGE50 is a Class I horizontal axis small wind turbine for on-grid households and businesses. It is a 50 kW wind turbine with two generator design, a 200 m2 rotor area and 36 m monopole tower.
The main benefits of TUGE50 are:
Great return-on-investment due to favorable price
Easy and low-cost maintenance - once in 5 years!
Two generators for maximum efficiency
Frequently asked questions
Here You will find a collection of articles to help You gather more information about small wind turbines. Below we will answer questions like "What is a small wind turbine?", "How to choose a best spot for my wind generator?", "How to find a good wind turbine?" and many more.
There are many definitions for a small wind turbine. The international standard defines it by the rotor swept area, but the more common definition is by the power rating (kW).
Countries usually have their own classification. For example, in Estonia it is up to 200 kW, while in Denmark it can be considered up to 25 kW and up to 60 kW in Italy. These definitions are not strictly technical, but are defined according to the access to financial green energy support schemes. For example in Denmark, the 60 kW wind generator, while technically belonging to the small wind class, will not receive small wind support.
A small wind turbine, irregardless of its class, will consist of the following:
2 or 3 blades
Nacelle with 1 or 2 generators
The larger the blades, the better it is. They are defined either by blade length (usually not more than 10 m), rotor diameter (up to 22-23 m) or swept area (rarely above 300 m2). Blades should be compared between generators of the same power (a 10 kW generator with a 5 m blade will produce more energy than a 10 kW generator with a 3.5 m blade). However, larger blades mean that the turbine is more expensive.
The wind turbine is, first and foremost, an investment, so a good wind turbine will pay for itself in a reasonable time and will start generating income (both financial and environmental) after that.
In order for a wind turbine to be a good investment, it has to have a good price to performance ratio. A wind turbine with lower performance and with a lower price may have a better ratio than a more expensive turbine with higher performance (and vice versa).
There are several parameters that must be taken into account when calculating the return on investment of a small wind turbine.
First of all, You will need to calculate lifetime costs. They usually consist of small wind turbine initial price, transport costs, installation costs (foundation price plus actual work) and maintenance costs (yearly maintenance fee multiplied by small wind turbine lifetime, usually around 20 years).
Since small wind turbines are usually installed at relatively low heights, they are very susceptible to turbulence. Thus, it is very important to minimize this influence by carefully choosing the exact spot for a wind turbine installation. For example, the photo on this page is a good example of a bad spot.
Wind turbulence has a drastic effect on a small wind turbine perfomance, it introduces additional mechanical stress to blades and construction and reduces the energy output. Turbulence is created by surrounding objects (buildings, trees, etc) and landscape details (hills, valleys, etc).
There are many ways how a small wind turbine may be useful just for You (depending on particular circumstances), but there are a few unique advantages that a small wind turbine has and here are top three of them:
1. A small wind turbine is a stable and passive investment.
2. A small wind turbine compliments solar power.
3. And last but not least - a small wind turbine actually does help the environment.
These are the three main benefits of small wind turbines and this is why we love building them! But, truth be told, some things may not be so great in certain circumstances, so read more to learn all about it.
What are the disadvantages of a small wind turbine?
As a manufacturer of residential wind turbines and wind energy enthusiasts, we want everyone to own a small wind generator. However, if there is not enough space for a tower and You are thinking about installing a small wind turbine on the rood of Your house, then we strongly recommend You to forget that idea and install solar panels instead - and here is why:
1. They may cause structural damage.
Making a roof-mounted wind turbine with cheaper price (due to lower size and no tower) wouldnt be a problem for our company. Neither would be selling it to a large number of customers due to low price, easier installation and a larger customer base. There is a reason why we refuse to make profit on this and this reason is that roof-mounted small wind turbines are simply not good!
Vertical axis wind turbine, or VAWT, is any turbine with vertical axis of rotation. There are many sub-types of these turbines, but the technology itself has some general advantages and disadvantages when compared with horizontal axis wind turbines.
One advantage is that VAWTs are omni-directional and can utilize all ranges of wind directions and utilize gusts of wind. On the other hand, since wind is still blowing only from one direction, this creates uneven dynamic loads on different blades and other components, which makes it less reliable. Also, it leads to a certain amount of self-braking, as the same blade passes the wind flow at different angles.
A combination of different renewable generators is called a hybrid system and there are several advantages to such a configuration.
The first is that usually there is a high level of complementarity between available wind and solar energy. While the day cycle complementarity is relatively low, most locations show a significant complementarity in annual cycles. It means that when wind is weak, the sun shines brighter and vice versa, which leads to more stable and reliable energy generation. Studies show that combining wind and solar in the right ratio can reduce the optimal battery bank size almost two times.
