WINDSPOT wind turbines have been designed according to the most exacting standards of quality.  For this, the IEC 61400-2 standard has been taken as a reference point and we have been working on certification with some of the most important organizations in Spain and Europe such as CIEMAT in Spain and SEPEN in France.

The predicted useful life of each wind turbine, following the preventive maintenance recommended, is 25 years, making it an economic and safe investment.
For this, high quality materials have been chosen which are resistant to corrosion and the passing of time.

WINDSPOT is designed to function at its best with a minimum maintenance consisting of a review every 18 months and it is guaranteed against every material defect. The period of guarantee is 24 months extended from the moment of purchase.

The noise measurements carried out by SONKYOENERGY at their facilities gave the following results:

At a distance of 60 metres and a constant wind of 8 m/s, a noise of 45 dB (A) was registered (according to BWEA standards).

The following table gives a reference of the intensities of the noise generated by some typical sources.

The correct placement of a WINDSPOT wind turbine is as important as the wind available. There are some important considerations that should be taken into account:

• The ground: Normally, the highest point has the best winds, although areas around rivers, valleys, large hills or mountains, and large wooded areas can affect the available wind resource.
• Obstructions: Obstructions are considered to be any obstacle that interferes with the direction of the wind, affecting its direction and speed. The most common are houses and trees. Generally it is recommended to install the tower 10 meters higher than the tallest obstacle around and at a distance more than twice the height of the obstacle. For example, if you have a house 5 meters tall and a tree 7 meters tall near where you want to install your WINDSPOT 3.5, it would be necessary to put it at a height of 17 meters (7 m from the tallest obstacle + 10 m) and 10 meterts from the house (5 x 2) and 14 meters from the tree (7 x 2).
  
• Predominant winds: It is important to know from where the strongest and most frequent winds originate in the area where you want to install your WINDSPOT. That direction should be free from obstructions. To know this information, it is usual to resort to studies carried out with an anemometer that measure the direction and speed of the wind in a specific time period. This forms what are called "wind roses". Below is an example of these wind roses in the same place, but one in summer and another in winter. As can be appreciated, they are completely different, for which a detailed study of the electricity demand in both stations will be very useful.
  
  

Buying a WINDSPOT wind turbine is not only an investment in a product of quality, effeciency and reliability, but saves a lot of CO2 from being emitted to the atmosphere.

This quantity represents the CO2 that has been saved by not producing energy from fossil fuels and is obtained by multiplying the energy generated annually by the average CO2 emitted by conventional sources.

The approximate quantity of CO2 emitted by each of the different energy sources is the following:

 

1 kwh produced with: Emits (kg de CO2):	Emits (kg de CO2):
Coal	0.75 kg (approximate value and dependent on the type of coal)
Fuel oil or diesel oil	0.60 kg
"Natural" gas, conventional centre	0.37 kg
"Natural" gas, combined cycle centre	0.26 kg
Nuclear	little, but not negligible (uranium mining, transport, etc)
Hydraulic	negligible
Wind	negligible

If there is an extra demand, this extra cannot be generated with either nuclear, wind or hydraulic. Only coal and fuel oil can increase the production at power stations, for which if we save 1Kwh, we will save the equivalent in coal or fuel oil.

For example, with a medium wind of 7 m/s, the different WINDSPOT models would avoid an annual emission of:

 

WINDSPOT 1.5	3160 kg de CO2
WINDSPOT 3.5	7400 kg de CO2
WINDSPOT 7.5	15800 kg de CO2
WINDSPOT 15	31600 kg de CO2
