BWC EXCEL Wind Turbine |
The BWC EXCEL is a modern 6.7 meter (22 ft) diameter, 10,000W wind
turbine designed for high reliability, low maintenance, and automatic
operation in adverse weather conditions. It is available in two
configurations: battery charging and grid-connected (the pumping version
is not currently available). 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 48, 120 or
240 VDC. They are well suited for large rural homes, remote villages and
facilities, eco-tourism resorts, and larger telecommunications sites.
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 $21,900 to $27,900.
The BWC EXCEL is most often installed on a guyed lattice tower, which is
available in heights of 18 m (60 ft.) to 43 m (140 ft.). Prices range from
$7,400 to $12,680. Tilt-up versions of these towers are available for
sites without crane access. Non-guyed lattice type towers and monopoles
(tapered tubular) towers are also available to heights of 37 m (120 ft).
Customers may also supply their own towers if they follow BWC's technical
requirements for Excel towers (see
Requirements).The BWC EXCEL was
introduced in 1983 and it has been installed at over 900 sites around the
world. We invite you to review our list of
notable customers and
