In the city, the convenience (installation) and efficiency ratio of wind power <(wind energy capability) continuous wind supply and wind efficiency (wind level)> are zero
The cost of wind energy is higher than the cost of solar energy 20 percentage points lower.
The power you mentioned is at least 3000W (a prerequisite for trouble-free long-term operation)
It can also be a group or 100W level power generation. Of course, the breeze needs to be around level 2-3
The most important thing is the cost. Although it is not high, the cost according to what you said is about 100,000 yuan.
100,000 yuan , a 1.5 HP on-hook operation for 8 hours only consumes 4 kilowatt-hours of electricity, and the cabinet machine does not exceed one kilowatt-hour of electricity per hour. Of course, there are even lower energy efficiency models now. For 100,000 yuan, I think you can use the air conditioner for a lifetime. .
How to make your own wind turbine
It depends on whether you want to generate DC power or AC power. Find a corresponding permanent magnet low-speed motor, install the fan blades, and place it in the wind. Then, the original motor leads will generate voltage, the voltage size is related to the speed, and the AC and DC are related to the motor type. This method can 100% generate electricity, but the voltage generated is unstable and requires a voltage stabilizing device. The power generated depends on the power and speed of the motor. Generally speaking, the electricity generated by the DC generator can directly drive the LED lights. As the wind changes at night, the lights will flash, which is very beautiful.

In the process of converting wind energy into mechanical energy~
The mechanical power is required to be as high as possible~ < /p>
The weight of the windmill blades is smaller~
There is also a difference in how many blades you choose~
This needs to be tested by yourself~
You also need one Transmission speed change device~
Since the speed of the windmill will not be too high~
It is necessary to use a speed change device to speed up the speed~
Just use a gearbox~
p>
This step of converting mechanical energy into electrical energy~
Since the voltage required by lz is not large~
It is enough to use a general fixed magnetic pole generator~
The output voltage is unstable~
If necessary, add a voltage stabilizing circuit to the output~
