Wind Energy








About.

Although wind has been harnessed for centuries, it has only emerged as a major part of our energy solution quite recently.

Applyed correctly, small wind is an effective means of generating your own energy. Whether it is a stand alone system for charging a few batteries or a remotely operated hybrid system for telecommunications. Combined with solar power, wind plays an integral part of an energy system for a constant source of power, anywhere.

Small PV Installation

Benefits.

Just like with Solar PV, once installed Wind Turbines, require very little maintenance whilst at the same time generating a great deal of free electricity. Wind Turbines can also be installed for both off-grid and on-grid system and in both instances can take advantage of the government ensured FITs and ROCs.

Checklist.

Investing in wind is like any investment, it needs to be researched properly. We've created this brief guide to assist you in these first steps:


Is Wind right for me?
The first question you should ask yourself is if installing a wind turbine is the right choice for you. The site is of ultimate importance when installing any wind system. Although there are some online sources that can help you estimate your wind speed, on a small scale wind varies greatly and these online sources may not be precise enough for your specific location.

Where should I install?
The siting of a wind turbine is quite possibly the most important question you will face. Densely urban areas are not suitable for larger wind turbines, and at least 1 acre of land is advisable to ensure optimum siting of micro wind generators. All wind turbines work best in exposed locations, or when they're positioned high enough to reduce turbulence caused by obstacles, or ground clutter, such as trees, buildings, poles, structures and high crops.

Because of the nature of wind, accessing higher wind speeds will result in much higher power production. In fact, if you managed to double your average wind speed, you would receive approximately 8 times more power! Simply put, obstacles will negatively impact your wind turbine's performance, so it becomes imperative to position your wind turbine in a location and height where it will be above all nearby obstacles.

The prevailing wind in the UK is generally from the South West.

Towers
The importance of the correct tower can be underestimated. Taller towers can bring real benefits: the higher up you can get the turbine, the higher the wind speeds and the lesser the turbulences. They might be more costly, but in most situations, they increase the return on investment.

There are various mounting options with wind turbines: guyed, self-supporting, hinged gin pole and ram operated folding monopoles. With sizes ranging from 7 m to 49 m, you can choose a tower height that suits your needs.

Access to wind is the key, though even lower bands of wind can be harvested with the right machine. Some of our customers can also install their wind turbine onto an existing structure such as a telecomunications tower. Our wind turbine towers are all manufactured in the UK.

Grid Connection
(This needs to be confirmed for the size of turbine being connected) The UK regulation requirements are:

For small systems (less than 16 amps per phase). These should conform with Engineering Recommendation G83, which just requires the DNO to be notified. Our Kestrel e400nb 3.5 kW falls under these regulations.

For larger or multiple systems. These should conform with G59/2, which requires prior approval from the DNO and also (at their discretion) the witnessing of the connection.

Please remember that we can help with all of these decision so please
