Around 150~200. The number of bolts is related to the installation structure of the wind turbine. Wind turbines are mostly installed in the horizontal direction. The number of bolts is about 150 to 200 in order to fix the generator on a solid foundation and enable the generator to operate safely and reliably. Bolts are required to be high-strength, corrosion-resistant, and durable to ensure that the wind turbine can be installed as designed and operate safely and reliably.
Note: 1. Do not get too close to other objects on the roof, such as water tanks, etc. If they are too close, the wind blades will hit them. 2. Generators near the wind will produce electromagnetic interference. Do not have radio transmitting and receiving equipment such as antennas nearby. 3. The generator makes a certain amount of noise, so do not disturb other residents. 4. The load-bearing capacity of the roof. If the generator is too large, the roof will not be able to bear it. 5. Pay attention to the wind direction. If there is something higher than your home next to you that is right in the wind outlet, that won’t work. 6. Pay attention to lightning protection. 7. Choose the model according to the number of windy days and the size of the wind. If the wind is light, you do not need to install a large generator. 8. Installation and fixation must be firm, and the final footings are placed on the main beam. 9. There are more factors to consider in urban areas.
