System Meets
Power Needs at Darby Home
 The
rushing waters of Boulder Creek 20 miles south of Darby, Montana, provide power
for all the 110-volt needs and one 220-volt application for a home in the woods.
The system uses an ES&D turbo suitable for low-head generation. With only
25 feet of head, the system puts out more than 400 watts and is grid-intertied
for net metering, considerably reducing the electric bill. The system, installed
by the owner and purchased from Solar
Plexus of Missoula, also employs eight L16 Trojan batteries (for stand-alone
capacity), a 4024 sine wave inverter and C40 controller and disconnect.
Ravalli County and the Natural Resources Conservation Service have permitted the
system.
