About How many watts does a wind turbine fan have
Wind turbines commonly produce considerably less than rated capacity, which is the maximum amount of power it could produce if it ran all the time. For example, a 1.5-megawatt wind turbine with an efficiency factor of 33 percent may produce only half a megawatt in a year — less if the wind isn't blowing reliably.

For example, a 1.5-megawatt wind turbine with an efficiency factor of 33 percent may produce only half a megawatt in a year — less if the wind isn't blowing reliably.
Extracting energy from wind is conceptually simple: wind moves over fan blades that turn a shaft that rotates an electric generator. The power capacity of a wind turbine is easily calculated, and yes, it does depend on turbine size.
A 500 W wind turbine has 12 kWh rated output (the total energy capacity). Since wind turbines are highly dependent on other factors such as wind strength, weather conditions, and many more, they can only produce up to 80% of their original rated output. Hence, we look at their actual output as the real energy generated.
The average efficiency of a small wind turbine is 20-35%. So, a 1kWh turbine will generate 200-350 watts of power on average. Homeowners often opt for 5kW small wind turbines when they only need 1kW of power. This gives them a buffer to generate enough electricity even when the wind isn’t blowing as hard as usual.
Wind turbines have a power rating usually ranging from 250 watts (enough to charge a battery) to 10 kilowatts (enough to power a house) to six megawatts (enough to power more than 1600 houses). Just as the wind constantly changes, wind turbines are built to operate within a wide range of wind. Read more from the Sci NC team.

6 FAQs about [How many watts does a wind turbine fan have ]
How much power does a wind turbine have?
Wind turbines have a power rating usually ranging from 250 watts (enough to charge a battery) to 10 kilowatts (enough to power a house) to six megawatts (enough to power more than 1600 houses). Just as the wind constantly changes, wind turbines are built to operate within a wide range of wind. Read more from the Sci NC team.
How much power does a 1kWh wind turbine generate?
It is important to note that wind turbines are not 100% efficient. This caveat means that a 1kWh turbine will never generate 1,000 watts. The average efficiency of a small wind turbine is 20-35%. So, a 1kWh turbine will generate 200-350 watts of power on average. Homeowners often opt for 5kW small wind turbines when they only need 1kW of power.
How many homes can a wind turbine power?
The world's biggest offshore wind turbines can now make 13 megawatts, since they can be built much taller and winds are stronger and more persistent out at sea. If a 2MW turbine can power 1000 homes, simply scaling up the numbers, you'd expect a 13MW turbine to be able to power about 6500 homes.
How much energy does a 500 watt wind turbine produce?
A 500 W wind turbine has 12 kWh rated output (the total energy capacity). Since wind turbines are highly dependent on other factors such as wind strength, weather conditions, and many more, they can only produce up to 80% of their original rated output. Hence, we look at their actual output as the real energy generated.
What is the rated power of a wind turbine?
Thus the rated power of a wind turbine is the power that the turbine will produce at a particular wind speed. The curve below shows an example ‘power curve’ for a wind turbine rated at 1000W. You’ll note that the power doesn’t start increasing at zero wind speed: each turbine has a ‘cut-in’ wind speed at which it starts to produce power.
What is the capacity factor of a wind turbine?
Engineers use a term called ‘Capacity Factor’ to calculate the amount of energy from a wind turbine. The capacity factor, expressed as a percentage, is the actual energy output from a turbine over a year, divided by the energy output that would be obtained by the turbine operating at its rated power over a year.
