Westwind - Serious Power Generation

Segen offer 10kW and 20kW turbines from the long established Australian manufacturer, Westwind. The Westwind business was purchased by Northern Ireland based J. A. Graham Ltd in November 2006 and the production facility has recently been moved to Northern Ireland. The Westwind 10 and 20 are well tried and tested products with many installations world wide, and Segen is very pleased to be working with J. A. Graham to promote the product in the UK.

If you are new to small wind turbines, please start by reading our Frequently Asked Questions (FAQ) pages, as those form a complete guide to wind resource and wind turbine siting. Not all sites are suitable for a wind turbine, so please ensure you read this information carefully in relation to your proposed location.

The Westwind 20 is ideally suited to the more power hungry needs of farms, larger domestic rural properties, schools, council premises and commercial properties, generating approximately 30MWh on an average site, and more in windier locations. A typical fully installed cost would be between £50,000 and £60,000 depending upon local conditions.

The Westwind 10 may be more appropriate for smaller requirements or where planning, grid restrictions or cost may mandate a smaller turbine. A typical fully installed cost would be between £30,000 and £35,000 depending upon local conditions.

The Westwind 20 is supplied on a 15m or 18m free standing tower, thereby maximising the energy available from this larger machine and normally connects to a three phase supply. It is fully accredited under the Low Carbon Buildings Program, enabling the full £2,500 grant to be claimed for domestic installations.

Power Curve

The Westwind 10 and 20 are both rated by the manufacturer at 14m/s. Shown to the right is a comparison of the Westwind 10 and 20 measured power curves. The annual energy generated by each turbine is very dependent upon many factors, including tower height, wind speed and any local obstructions. For more information on these aspects please read our FAQ pages which form a complete guide to buying a wind turbine.

Technical Specifications

Summarised below are the technical specifications of the Westwind 10 and 20kW turbines.
