Bergey Excel 10



The BWC Excel 10 is a modern 7 meter (23 ft) diameter, 10 kW wind turbine designed for high reliability, low maintenance, and automatic operation in adverse weather conditions.


Large rural homes

Connected to the grid or not, the Excel 10 can provide most of the electricity for an average total electric home at moderate wind sites. The Powersync II inverter is the most advanced in the industry and it carries a full UL certification to the latest utility standards.


The Excel 10 is widely used in farming operations in rural and urban settings.

Small Businesses

Small wind systems qualify for accelerated depreciation, making it more affordable than ever for businesses to offset their electricity costs.

Why buy a small wind system?

A Bergey wind turbine is a smart investment that will lower your monthly expenses and increase your net worth. At the same time it will help clean the air, slow climate change, and move us towards energy independence.

You will also enjoy watching your utility meter turn backwards and the lively interaction between the wind and your Bergey turbine. Finally, it will totally change your view of wind – you will start appreciating windy days.

For those fortunate enough to have a windy site of at least one acre, a Bergey wind system will be substantially less expensive than a comparable solar system, it will take up less space, and its performance won’t degrade over time.

Tower Options

The Excel 10 is most often installed on a guyed-lattice tower, which is available in heights of 18 m (60 ft.) to 49 m (160 ft.). Tilt-up versions of these towers are available for sites without crane access in heights up to 30 m (100 ft.).

Self-supporting lattice towers and monopole towers are also available. Self-supporting lattice towers are available in heights of 18 m (60 ft.) to 49 m (160 ft) and monopole towers are available in heights of 18 m (60 ft.) to 37 m (120 ft.).

Customers may also supply their own towers if they follow BWC’s basic tower requirements for the Excel 10 turbine.

SWCC Certification (U.S.)

The Excel 10 is one of only a few wind turbines to have achieved the Small Wind Certification Council (SWCC) certification.
The SWCC is an independent organization that assesses and issues certificates and consumer labels for the performance and safety of small wind turbines in accordance with criteria established in the American Wind Energy Association (AWEA) 9.1-2009 standard.


The BWC Excel 10 was introduced in 1983 and it has been installed at over 2,500 sites around the world.
In 2009 the warranty on the Excel 10 wind turbine was increased to 10 years – the longest in the industry.


In 2008 the Excel 10 was upgraded to a more efficient Powersync II inverter.
In 2009 the Excel turbine was upgraded with a more powerful alternator and longer blades.
Performance has been improved by an average of 25%.
