Instructions for choosing the installation point.

1.
There are many techniques for choosing the location of a small wind turbine.
Your main aim should be to have the wind turbine installed in place where the winds are as strong and frequent as possible.
Do not try to locate the most suitable installation point using portable anemometers. It is futile. Farmers, fishermen and permanent residents of the area know best where the winds are strongest and most frequent. Consult them...
In general, the following simple principles apply:
- At the installation point, around and near the wind turbine, there should be no obstacles to the wind flow. The "Iasos" wind turbine can work equally efficiently in any wind direction. Therefore it is not enough to have no obstacles only in the direction from which you think the wind usually blows. If you follow such a logic, the efficiency of the wind turbine will be greatly reduced.
- The higher the wind turbine is from the ground, the greater its efficiency will be, because as the height increases, the speed of the wind also increases. But you don't need to resort to exaggerations, making special pedestals and pillars. The turbine of the wind turbine is anyway than 2.5 m far away from the ground. If you decide to build a raised pedestal, consult a specialist engineer.
- From the following three methods of selecting a wind turbine installation point, we recommend the second or third method:
a.
The first method, the scientific method, is based on detailed measurements of the wind potential of the area where the wind turbine is to be installed. It requires many months of scientific research and is expensive. This method is followed by large companies that intend to invest a lot of money installing horizontal axis wind turbines on mountain tops. One of the advantages of this method is that the wind data concerns the installation point of the wind turbine and not some other point or a wider area.
b.
The second method is also scientific, but it costs almost zero. In this method we use the wind data, as shown in the "wind rose" of the area closest to the point where the wind turbine will be installed. The results obtained using this method of estimating the wind potential have only a small deviation from reality and are subject to almost the same probability of verification as the data of the previous method. The disadvantage of this method is that the "wind rose" probably concerns an area that is quite far from the installation point of the wind turbine. For example, it is easy to get the "wind rose" of the nearest airport (which is usually located in a plain), but the installation site of the wind turbine is not only far from the airport, but on the other side of a hill...
In order to extract the wind data from "wind rose" and use it to make estimates about the amounts of electricity that can be produced by the "Iasos" wind turbine, you should download from our company's website the special free software and the corresponding instructions for use. You can also find a related video on our website.
The "wind rose" is a circle chart and looks like the one in the next image.

c.
The third method is based on the use of a single parameter, that of the "average annual wind speed".
From your country's weather service, try to get a wind potential map of your area (one year long). Try to have the map refer to as recent a year as possible. The wind potential map looks like the map in the next image.
Average annual wind speed
It is very easy and free of cost for everyone to locate the average annual wind speed of their area on meteorological maps. The disadvantage of this method is that the average annual wind speed of each region does not apply uniformly to each geographical point of the specific region. There are significant differences from one geographical point to another, in the duration and intensity of the winds, depending on the morphology of the ground. By moving the installation point of the wind turbine, even a few meters, you may achieve a significant difference in the wind potential.

2.
You can install the wind turbine away from the point of consumption.
In this case, it is better to install the "charger controller", batteries and "inverter" in the small room located at the base of the wind turbine. This means that from the wind turbine you will get 220 Acv or 110 Acv, i.e., the "final electric current" for consumption.
Keep in mind that, on the one hand, the room at the base of the wind turbine is not watertight, and on the other hand, it is very easy to be broken into by someone.
Connect the wind turbine to the consumption (for example your residence) using a simple three-conductor cable (for the scenario you get from the 220 ACV wind turbine). The cross-section of the ducts depends on the distance between the wind turbine and the point of consumption (for example your house).
The following table will help you choose the correct cable cross-section.

On the contrary, if you choose to place the "inverter" and the batteries in some other place, then you will get from the wind turbine 48 DCV the electric current, i.e., which is necessary to charge the batteries. In this case the cables you need are very expensive and you probably don't advantage to place the wind turbine far from where the batteries are located.
