Vertical axis wind turbine

In a vertical wind turbine, the main rotor shaft is set vertically, and the blades rotate around a vertical axis. It is different from a horizontal wind turbine, where the blades rotate around a horizontal axis.

Quick overview of a vertical wind turbine

A vertical wind turbine's design is pretty compact. It can be installed with ease in smaller areas, making it suitable for locations where the space is limited. The vertical axis wind turbine does not depend on wind direction, which is why it provides a more consistent and dependable output when it comes to power generation. It generally has a lower noise level and is less visually hindering than horizontal wind turbines.

How to install a vertical wind turbine?

Installing a residential vertical wind turbine involves a couple of steps that will lead to harnessing wind energy effectively. First, pick an appropriate location that gets consistent wind flow. Areas with obstructions like tall buildings and trees will not make a good location. Ensure that the chosen site has enough clearance for the turbine's height. Dig a hole for the foundation of the wind turbine. Pour concrete and insert anchor bolts or add rebars to make it stable and strong. Assemble the turbine following the manufacturer's instructions. Attach the blades, hub, and generator to the tower. Now is the time to erect the tower vertically. Secure it to the foundation using anchor bolts or any other method that fits the needs. Connect the turbine's electrical wires to the charge controller or inverter. Run underground cables to the battery bank or grid connection point. Use a crane or winch to lift the assembled turbine onto the tower. Once this is done, turn the turbine on and monitor its performance.

Some people choose to DIY vertical wind turbines. While it is a perfectly doable project, it is better to gather all the necessary information beforehand to have enough knowledge in case there is a need for troubleshooting.

How to maintain a vertical wind turbine?

Maintaining a vertical wind turbine is very important to keep it effectively up and running for a very long time. First things first, regularly check the bearings for any visible signs of wear and tear. Lubricate them as often as needed. Check all the main components, including the blades, nacelle, and generator, for any damage. Ensure that all the buts and bolts are tight and secured in place. Also, check the electrical connections for loose wires or damaged insulation. It is important to address these issues as soon as they surface to prevent electrical problems.

Clean the blades regularly in order to prevent dust or debris from building up. Bird droppings are also a major issue in wind turbines. Make sure everything is cleaned properly. Inspect the blades for cracks or damage as well. Repair them if the damage is small, and immediately replace them if they are damaged beyond repair. Lubricate moving parts such as bearings and gears according to the manufacturer's recommendations. Use appropriate lubricants to prevent friction and wear. Survey the tower foundation for stability and any signs of settling. Check the tower structure for rust, corrosion, or damage.
