    Generating electricity by yourself is an easy way to cut the electric bill in half. Although solar energy is generally an environmentally friendly option, for people living in areas with reliable wind conditions, wind power is an excellent energy resource.

    Whether you live in a rural area with no access to an electric grid or in a suburb and want to reduce your electric bill, a home wind turbine is a great choice. All it requires is a little technical knowledge, land, and a high-voltage battery bank. For about $800, you can buy a mid-range home wind turbine that can easily meet your needs.

    Working principle of a Home Wind Turbine 

    The wind is used to produce a form of useful energy. Wind energy is a type of kinetic energy. Wind turbine takes this kinetic energy from the wind and transforms it into mechanical energy, which can be converted into electrical power using a generator.

    The working principle of the wind turbine is based on turning the energy of the wind into electricity by utilizing the aerodynamic force created by the wind turbine rotating blades. As the wind passes through these blades, the air pressure drops from one side to the side of the blade. So, a pressure difference is created which results in drag and lift forces, similar to flying machines.

    The rotor of the wind turbine is connected to a generator via a drive turbine or shaft and gears. The aerodynamic force translates into the rotation of a generator, which then produces useful electricity.

    Although according to Mother Earth News, at least one acre of land is needed for the wind turbine to work usefully, it often depends on what wattage you are trying to obtain and also the turbine actual size. However, the important issue that has to be considered while making a decision for the use of a home wind turbine is zoning and local homeowner conditions.

    Many of these conditions prevent a user from installing a large turbine powerful enough to run all the household devices in urban areas.

    Additionally, the larger space where the turbine is located, the higher the wind speed created and the higher the energy level. Buildings and other constructed objects in an urban yard reduce wind speed that can potentially be used to supply a home wind turbine generator.

    But, if you meet the zoning and homeowners requirements, you can still successfully install and employ small wind turbines.

    However, if you want to supply your electricity demands totally off the grid, you should consider a combination of wind and solar power to fully power the home, particularly in urban or areas with poor wind conditions.

    A parameter that plays an important role in the study of wind turbines is the rating wind speed, which is defined as the speed at which the wind turbine has the maximum output power. For home wind turbines, this value is usually less than 20 m/s. This parameter must be differentiated from the cut-off and the cut-in wind speed.

    Home wind turbines usually have a power output in the range of 200 W to 800 W. However, some wind turbines can generate a power output of as much as 2000 W.

    To calculate the output of a wind turbine, the following formula is used:

     

    Power=\frac{1}{2}C_{p}\rho AV^{3}
     

    where:

    P and Cp are power output (watts) and maximum power coefficient (a dimensionless variable ranging from 0.25 to 0.45 with a theoretical maximum of 0.59). Also, ρ and V are air density (kg/m³) and wind speed (m/s), respectively.

    A is the rotor swept area in m² calculated by the following relation:

     

    A=\frac{\pi D^{2}}{4}
     

    D is the rotor diameter in m.

    What is Wind Turbine? The Short and Essential Answer

    Benefits of Home Wind Turbine

    There are some advantages to using wind energy for your homes.

    Clean and Renewable Energy Source 

    Perhaps the main reason for investing in wind power is that wind energy is a source of clean and renewable energy. Like solar power, wind power uses an abundant power source that does not require any destruction of land, smoke creation, and overuse of natural resources.

    Friendly Energy Source 

    After calculating the initial cost and, of course, commissioning wind power which is relatively expensive, the power of a home windmill is free. You do not need to plug into an electric company to be charged.

    Possibility of Installation by Anyone 

    Note that we are talking about small home wind turbines, not the gigantic ones on the windmill farms. So, most people can install these smaller wind turbines in a few hours or less on their own. The kits come with all the necessary components and detailed instructions for placement, operation, and answers to essential questions.

    Safe 

    In the case of safe installation in which the assigned information and setup meet the conditions of the home and land, these turbines can be securely established.

    The main challenge against safety is that the wind turbine may be damaged, and one of its large blades may fall. Then, it may land on someone nearby. This is not generally an issue for home turbines because they are not so huge to cause permanent injury. However, precautions should be taken to ensure that the blades are not damaged after storms or severe windy conditions.

    Drawbacks of Home Wind Turbine 

    Weaknesses of home wind turbines include the following:

    Low Quality of Low-cost turbines 

    Currently, low-cost turbines have higher quality than those used five years ago. However, they are still more challenging than the good ones made by reliable manufacturers. Remember that cheap products offer cheap warranties, whether or not they are valid.

    Also, you should watch out for turbines that are on the approved lists for discount programs.

    Many of these are lower quality products by manufacturers who test the turbines and rate them higher than the actual rate to be included in the list.

    Lifetime 

    Wind turbines have lifespans shorter than solar panels which last more than twenty years.

    Need for Frequent Maintenance (Heading 3)

    As they have many parts, they require frequent maintenance. Thus, a high-quality product is an essential point to consider. However, even if you buy a good product, you need to replace some pieces from time to time.

    You should inspect your turbine annually for safety considerations. Also, it is recommended to check additionally after any severe storms or winds.

    Types of Wind Turbines: The Quick and Easy Intro

    Home Wind Turbine Parts 

    There are several parts in a full wind turbine kit.

    Turbine 

    Most home wind turbines produced today are similar to those in large wind farms. They include a machine on top of a tall tower with a horizontal axis for installing three blades to rotate a rotor. Blades for home-based units are typically made of a composite material such as fiberglass instead of steel.

    The turbine frame is what the other components of the unit are connected to. The amount of energy generated by a turbine depends primarily on the rotor diameter, which determines how much wind can be harnessed by the turbine. A tail placed on the opposite side of the blades holds the turbine facing the wind.

    Towers 

    As stated above, the speed of the wind increases with height. So, the best chance of running a successful wind turbine generator is to install the system on a tower. The higher the tower, the more power produced.

    It does not take much cost or attempt to raise the tower height. According to the quantity of power that can be generated, look at this general rule: Raising a 10-kilowatt generator from 60 to 100 feet may cost 10% more, but it can generate 25% more power.

    But installing the towers can be difficult. You are faced with a long piece of equipment that must be effectively secured. When you buy a wind turbine kit for home use, you will find that most of them include a tower to build.

    There are two types of towers for home wind powers: free-standing (self-supporting) and guyed types. The latter is more common, less expensive, and easier to mount than the other type. The problem is that the guy wires must have a radius of one-half to three-quarters of the height of the tower. Thus, you need ample space to accommodate all the tools.

    Self-supporting towers offer a simple approach to conduct maintenance on the turbine. Some self-supporting towers have a tilt-down feature that enables the turbine to be lowered to the ground in hazardous weather such as storms.

    Other Components 

    Except for the two mentioned basic parts, other components depend on your needs. Supplying a battery requires different parts compared to a water pumping system.

    It is important to check whether the wind power system is connected to the power grid or is wholly off-grid, or even a combination. Depending on these conditions, you can buy the right package for the user.

    Suppose that you need a home wind power generator that supplements the existing energy grid. The components you require are

    • a controller
    • storage batteries
    • wiring
    • an inverter for conditioning power
    • an electrical disconnect switch
    • a foundation for the tower
    • a grounding system
