Types of Wind Turbines

There are many different types and each have advantages depending on where they are placed and what they are used for.

Grid tied versus Battery Connected

Grid tied turbines feed power directly into your home whilst you are using appliances. If the turbine is generating power and you are not using it, it is fed directly into the national grid. Currently there are no financial incentives for home owners but this is likely to change next year. Battery connected systems store this excess energy in large batteries. This is slightly more efficient but not as cost effective. Batteries need regular maintenance and manufacturer’s warranties are not sufficient to make this a viable option at present.

Tower (Free standing and guy wire) and (lattice)
The free standing is the most typical type where you see a poll supported only by a large base plate. A second variation of this is where you see “guy wires” attached to the sides of the poll, supporting it (often 4 or 8 wires in all)

Free Standing or Guy Wire

This type is probably the least familiar and is often best suited for commercial applications where aesthetics are less of an issue.

There are two main types of wind turbine. Vertical Axis Wind Turbines also known as (VAWT’s) and Horizontal Axis Wind Turbines (HAWT’s). HAWT’s are much more common in domestic situations and the most familiar type. VAWT’s are more suited to commercial applications and are excellent at operating in confused wind areas. They are less aesthetically pleasing but very effective at lower wind speeds.

The most important factors we recognise when choosing a wind turbine are;

Demand for electricity
When you use it

The price of electricity in Ireland is rising and only recently have micro turbines made sense for home owners.
A typical house using 8,000 kilowatts of electricity each year will spend €1,450 on energy and €140 on ESB standing charges. A 2.5kW turbine on a good site would reduce this bill by 60%+ / €900+ at current prices. (ESB have announced an undisclosed increase in January 2009)

When you use it,
Wind turbines have an output coincident with the domestic power curve. They produce more power during the day than they do at night and more power in the winter than in the summer when we tend to have higher demands for lighting and heating.

We will look up your site on our wind maps and establish an estimate of output. As wind speed increases for every meter higher the turbine is placed, we will look to erect the turbine to the highest limits within the planning permission exemptions. (13 meters for domestic and 20 meters for commercial sites)

Commercial Wind Turbines also available
