Wind turbine power
Wind is the “fuel” for your wind generator. The power in
the wind can be transferred to electric power. The
amount of transferred power is directly proportional to
the density of the air, the area swept out by the rotor,
and the cube of the wind speed.
P=½αρπr²v³
The power P available in the wind is given by:
P = power in watts
α
= efficiency constant
ρ
= mass density of air in kilograms per cubic meter
r = radius of the wind turbine in meters
v = velocity of the air in meters per second

Density
The higher a wind generator is from sea level, the lower
the air density. Air density is directly proportional to the
output of your turbine.

Wind maps are available for many countries which will
give you an idea of the wind resource at the site where
you are planning to install. Check out these maps and
see if you have sufficient wind resource.

Choose the right controller for the system
•
Rated Solar Current should be more than Rated
Power of Solar Panel.
•
Rated Load Current should be sufficient to cover
overall load current.
Choose right Inverter for the system
•
Make sure input voltage and out put voltage for the
system.
•
Rated Load Current should be sufficient to cover
overall load current.
