The BWC EXCEL is a modern 7 meter (23 ft) diameter,
10,000W wind turbine designed for high reliability, low maintenance, and automatic
operation in adverse weather conditions. It is available in three configurations: battery
charging, water pumping, and grid-connected. The BWC Excel is a ruggedly built turbine
that comes with the longest warranty (5 years) in the industry.
Battery charging BWC EXCEL's can be supplied with outputs of 24, 48, 120 or 240 VDC. They
are well suited for large rural homes, remote villages and facilities, eco-tourism
resorts, and larger telecommunications sites.
As a water pumper, the BWC EXCEL can be located as much as 600 m (2,000 ft) from the well
to take advantage of improved wind conditions. It can replace small diesel pumps from 5 -
15 Hp for either drinking water supply or irrigation.
Connected to the grid, the BWC EXCEL can provide most of the electricity for an average
total electric home at moderate wind sites. The all new GridTek 10 power processor
(inverter) is the most advanced in the industry and it carries a full UL certification to
the latest utility standards.
Prices, which include a voltage regulator, pump controller, or a line-commutated inverter,
range from £17,000 to £19,500. For severe sites, an Extra-Stiff blade option is
available for an additional $395.
The BWC EXCEL is most often installed on a guyed lattice tower, which is available in
heights of 18 m (60 ft.) to 37 m (120 ft.). Prices range from £5,000 to £7,500. Tilt-up
versions of these towers are available for sites without crane access. A list of
requirements for customer supplied towers is available.
The BWC was
introduced in 1983 and it has been installed at over 600 sites around the world. We invite
you to review our list of notable customers and our example projects. |
