The exploitation of wind energy for wind power generation is a great boom. The electricity consumed in the world is mainly of fossil origin. Fossil fuels (coal, oil, gas) are responsible for a greenhouse that increases global warming.
Today, awareness of the risks to the environment (pollution for example ) leads to enthusiasm for renewable energy (solar, wind, geothermal, etc ), which is a factor that restores a place the exploitation of these energies, which are developing intensively throughout the world, driven by the need to address greenhouse gas emissions.
Here is what we’ll cover in this article :
Types of home wind turbines
There are two main types of wind turbines, both domestic and industrial.
Horizontal and vertical axis wind turbines. Each type certainly has advantages and disadvantages in terms of the lowest wind speed the turbine can produce electricity and also noise caused when its operational, etc.
Generating free power using a home wind turbine is one of the methods that fast growth in the world. To date, the most widespread wind turbines on the market are wind turbines with a vertical axis, the success of which is due to their profile (design ) of very interesting production. Another aspect, less visible, but that has all its small production units. In fact, they are increasingly most popular for a standing-alone operation to feed isolated sites and/or autonomous or, with the emergence of new vertical axis architectures, for urban exploitation.
Home wind turbines are not suitable for every place, there are many factors one must consider when choosing to install a home wind energy system. Even a small one requires an amount of space for installation ( roof or mounted ) and sufficient wind speed for the wind turbine to function. What matters?
Purchase guide to install a domestic wind turbine
It is essential, before you make any investment, to always ask for a quote and to contact recognized and trusted professionals. A domestic wind turbine can be bought in stores or on the Internet(Amazon & aliexpress) . But to benefit from aid and subsidies, the provided equipment and its installation must be carried out by a professional.
To choose the right wind turbine, each should be studied of the mentioned characteristics on the description. Certain elements may indicate that the dealer does not deserve your trust, and thus encourage you to spend your path.
For example, a power indicated in W / products per 24 h and not in W / h must make you doubt the honesty of this professional. Moreover, it should be noted that the mere mention of the [W] is not enough. This must be accompanied by a wind speed; most of the time, the energy is given corresponds to a wind of 40 km / h.
Main factors affecting the home wind turbine cost
A home wind turbine cost varies depends on some factors including :
- Capacity of the wind turbine (Estimated power kw or w )
- Quality of the wind turbine ( capable of producing
- Type of the wind turbine ( verticla axis or horizontal axis wind turbine ).
- Size of the wind turbine ( hight of the mat , number of blades )
Therefore, the bigger the power output (kW or w ) of the wind turbine, the higher its cost. In addition, whenever the wind turbine is made by a company with high-quality products, you will find that its price is higher than the turbines in the market or homemade turbines (designing a home wind turbine requires lots of technology ).
By shopping on Amazon and eBay sites, you will find the prices of domestic turbines range from approximately 40 to 1000 dollars, depending on the capacity (kW) and quality of the wind turbine.
In any case, I prefer American quality because American companies have a great interest in the field of wind turbines and offer great products.
So, in short, the factors affecting the cost of the turbine are:
Quality, capacity, a minimum wind speed that it can work on, turbine hardness, maintenance possibility…etc.

The cost of the turbine is not the only factor affecting the cost of the project, but the price of the other components like the inverter, wires, charge controller, and batteries (if you want a system isolated from the network) play an important role in increasing the cost of the project, especially if you are looking on components with good brands and you want a continuity in the work of the system and avoiding losses and a major failure I recommend the acquisition of high-quality brands.
Average costs of installing and running a wind turbine
The price of a wind energy system for individuals can vary greatly, not only rely on on the model, but also on the installer. It is therefore very difficult to give an indicative price.
However, once the domestic turbine is provided and put in by an expert for everyday use, costs area unit calculable to fluctuate between 29637.63 and $47420.20.
More advanced models for businesses and other operations agricultural and intended to resell energy can reach, as for them, the 106695.45 USD. In self-construction, the costs are much lower, but the wind turbine does not open then not entitled to aid. A self-constructed wind turbine costs between 1778.26 and 3556.50 USD That s in general of course.
are home wind turbines worth it ?
In America, and According to the clean power Association (AWEA), wind turbines cost between $3,000 to $5,000 for each power unit of power capability. most householders employing a turbine as their primary supply of electricity install between five to fifteen power unit of wind generation capability, that means they’ll expect to pay between $15,000 and $75,000 for his or her home wind energy project. These numbers don’t embrace any federal or state incentives.

Grid connecting and repurchase of energy
There are two options available If you opt for connection to the Grid and repurchase your energy produced :
- Resale of the entire production(chosen by individuals) :Because the primary purpose of building a domestic wind turbine is to produce its energy in a clean and autonomous way.
- Resale only the surplus. In this case ,the wind turbine is connected inside the house, with a consumption meter which is coupled to the low voltage Grid outside and to a second counter, called production, so that the surplus is recorded and re-injected.
The negative points of connection to the Grid
In reality, things are much more complex and much less profitable for individuals. In fact, only wind turbines meeting certain conditions, located in a wind development zone and having signed a buyback contract with a supplier resell their surplus. So you have to sign a contract to sell your energy.
Another negative point is that the feed-in price for electricity produced by a wind turbine is the lowest of all renewables in Europe. I don’t know if it is the same in America. It is currently 0.097$ / kWh from the first to the tenth year, and from 0.033 $ to 0.097$ / kWh from the tenth to the fifteenth year.
Finally, the numerous procedures with the electricity supplier. are long and tedious: it takes at least 4 months. The cost of connecting to the network is also high: between 1187.5 and 3,000 $ rely on the area. Faced with all these drawbacks, it is, therefore, better to do your calculations carefully
to be sure that a connection will be profitable.

Hi My name is Abd Allah i am web content creator and renewable energy phd engineer.
I started blogging since 2 years what make me create this blog is the importance of sharing information with readers who love this field, I think i m not the first one who is familiar with this field but every person has his touch.i love nature and i think renewable energy will take over the responsibility of preserving this beautiful world.
