Site Assessment for Wind Turbine Installation

By: Turbotricity  05/12/2011

You first need to ensure that your site is suitable for a wind turbine. Turbotrcity offer two options to help you assess your site:

  1. We can help you with a free desktop survey of your site
  2. We can call out and carry out a site assessment for you for a fee of €200

The suitability of your site will depend on a number of factors:

  • Whether the site is open to prevailing winds. Turbulence can significantly reduce turbine output if the turbine is downwind from buildings, trees or other obstacles
  • Size of site – ideally the turbine should be over 50m from your house or from neighbouring houses.
  • Shadow flicker – You need to position the turbine in such a way that the sun rising or setting at any time of the year does not cause a flickering shadow on windows in yours or your neighbour’s house. If there are days on which this occurs, we can programme your inverter to stop the turbine at such times, but there is a small additional charge for doing this work.
  • Ground conditions – our tower and foundation are designed for installation in clay. If your site has very deep topsoil, bog, or solid rock, we will need to quote for a suitably engineered solution to meet your needs.

Location of turbine within your site

You may like to consider where you want the turbine located. This should be far enough from your house to reduce noise, and if your site is sloping, would normally be close to the highest point. At the same time, if the cable from the turbine to the house is greater than 100m, there will be a small additional installation charge.

In prevailing winds, where possible, the turbine should not be downwind of any buildings, trees or other major obstacles that are less than 50m away. If this cannot be avoided, it will result in some loss of output. We can try to assess this loss, but it is difficult to accurately predict.

The turbine will be connected to your house using an underground cable. The path of this cable should be as short as possible, at the same time seeking to minimise disturbance to flower-beds, tarmacadam paths or other features.

If possible, the turbine should be located on the same side of the house as the fuse-board. However, if this is not feasible, our installers can run the necessary cabling.

Location of Power Management System

The cable from the turbine is connected to a controller and inverter, which is then connected to your grid. We would normally install these components beside the fuse-board if there is sufficient wall space.

However, if there is electricity in a garage our outhouse, you may prefer to install the power management components there. This can only be done if the cable connecting the garage or outhouse is capable of carrying the maximum output of the turbine (5-6kw).

If you wish to connect a computer to the inverter to monitor output and performance of the system, you should bear this in mind when considering where to locate the power management system.

For a small extra cost, we can install the power management system in an outdoor box under the roof eaves if preferred.

Planning Permission for Wind Turbines in Ireland

If you think this may apply to your site, you should consult with your Local Authority to ensure that your area is suitable and is not designated as a special area. This exemption may not apply if the installation is deemed to interfere with the character of a landscape or a view of special amenity.


Turbotricity - Wind Turbines

The blade profile is a computer aided design, using the latest aerodynamics software to optimise energy output for blade length, ensuring that the turbine has maximum strength in extreme wind conditions. The only maintenance required is an annual visual inspection by the owner, five-yearly inspection of blades with blade replacement after ten years and generator bearing replacement every 20 years.

The system can also integrate solar photovoltaic power and is Ideal for remote farmsteads, off grid telecommunications sites, and micro grids for villages in developing countries. Turbotricity has developed a unique control system which enables most small wind turbines to operate in sites that are off-grid. Turbotricity produces innovative solutions for small to medium scale renewable energy.


Wind Turbine Designs - Turbotricity

Smaller upwind turbines usually have a tail vane keeping the turbine facing the wind unless the wind speed gets too high, in which case the blade is allowed to swing out of the wind. However, vertical axis machines have an inherent inefficiency because while one blade is working well with the wind, other blades are effectively pulling in the wrong direction.
