BETZ LIMIT
All wind power cannot be
captured by rotor or air would
be completely still behind
rotor and not allow more wind
to pass through
Theoretical limit of rotor
efficiency is 59%
Most modern wind turbines
are in the 35 – 45% range.
Considering the efficiency as
30% an
output of 21.20 watts is
expected
STEPPER MOTOR SPECIFICATION
Obtained from old dot matrix
printer
12v – max current is 1 amps
Stepper motor will act as stepper
generator
6:1 gearing system is used
PHOTO VOLTAIC SYSTEM
• 18V output
• Pv system output is fed into the load
• Load used is fluroscent tube(9watts)
• Fluroscent lamp is the part of emergency
lamp with built in battery 6v-4Ah lead acid
rechargable
• LDR based solar tracking system
