We
highly recommend the BWC wind and solar hybrids for
our tractors. This package includes all of the components
needed to charge our tractor including: 1 kW XL.1 Turbine,
60’ Tilt up tower, 180 W PV Solar Panels and the
XL.1 Power Center.
The solar modules are Photowatt
24 VDC, 90 W modules designed to mount directly to the
wind turbine tower. No separate mounting structure
is required. Two modules are used to provide 180
W of solar capacity. The modules can be placed
well above the ground for security or to solve a shading
problem. The XL.1's PowerCenter provides voltage
regulation and can handle up to 750 W of solar.
The Tubular Tilt-up tower can be installed without concrete
and they tilt-up after all the assembly work is done
on the ground. The 60 ft. tower in this package is the
most common height used for the XL.1 turbine. For sites
with trees, taller towers are recommended. These towers
are available in height up to 100 ft.
In addition to the equipment costs given above, a complete
installation will typically include the following costs:
shipping, sales tax, permit costs, foundation and anchoring
(some soil types), turbine and tower erection, and inspection
fees. Your dealer or Bergey WindPower can assist you
in budgeting these additional costs. For budgeting
purposes, these costs typically range from $1,000 (customer
installed, no sales tax, etc) to $5,000 (Certified Dealer,
sales tax, etc).
If you would like to use this system for uses other
than with our tractor you optionally may purchase a
battery bank and/or AC Inverter. The optional battery
bank ($900) will provide 24VDC for other uses, maybe
to light up your shed or to provide backup refrigeration.
The batteries are Trojan T-105's, a workhorse of the
home power industry and an excellent value. A total
of eight individual batteries are connected in two parallel
strings of four batteries in series (24 VDC nominal).
This battery bank will supply up to several days of
power without wind energy input.
The optional ($1,044) Trace DR1524 modified-sine-wave
inverter provides 120 VAC (or 230 V, 50 Hz) and includes
battery-charging and transfer relay functions. A back-up
engine generator can be easily integrated, but it must
be manually started and stopped.
