Recomended for:

Large rural homes

Connected to the grid, 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. Small wind systems qualify for a 30% Federal Tax Credit, making them an even more affordable investment.


The Excel 10 is widely used in farming operations in rural and urban settings. Grants are available for agricultural producers and rural small businesses through the USDA’s Rural Energy for America Program. For more information click here.

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, increase your net worth, and help support American manufacturing jobs. 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 lease 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.


In October 2008 the Excel 10 was upgraded to a more efficient Powersync II inverter. In July 2009 the Excel turbine was upgraded with a more powerful alternator and longer blades. Performance has been improved by an average of 25%. Download 12 kW Powersync II Manual

SWCC Certification (U.S.)

The Excel 10 is one of two wind turbines to have achieved the Small Wind Certification Council (SWCC) certification to date. 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) standard.

MCS Certification (European)

The Excel 10 complies with the microgeneration certification scheme (MCS) which is the European standard for technologies used to produce electricity and heat from renewable sources. MCS is an EN45011 Scheme focused on ensuring the quality of renewable technology installations and products. Download Excel 10 MCS Summary Report.

Tower Options

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.


The BWC Excel 10 was introduced in 1983 and it has been installed at over 1,800 sites around the world.

In July 2009 the warranty on the Excel 10 wind turbine was increased to 10 years – the longest in the industry. Download Excel 10 Warranty Statement.
