#1. What is a home wind turbine?

A home wind turbine is in a range of nominal powers between 0.1 and 36 kW. The machine consists of a rotor, with a horizontal or vertical axis, mounted at the top of a mast. The rotor incorporates a generator that transforms the mechanical energy of the wind into a very low voltage current. This can be directed to storage batteries to power TBT devices (lights, alarm systems…). Previously, it goes through a regulator whose function is to protect the installation from overloads or deep discharges. An inverter connected to the regulator makes it possible to obtain an alternating current compatible with equipment operating on 230 V.

#2.Varied efficiency in the residential sector

The production capacity of a home wind turbine is expressed in kilowatt-hours (kWh). Its performance depends on several factors: blade size, mast height, terrain configuration … and, of course, nominal power. The machine needs a minimum wind speed to operate: generally from 3.5 m / s. It is configured to deliver the maximum of its power in a given wind range: for example, from 10 to 15 or 17 m / s. Then she picks up quickly. If the wind exceeds 25 m/s (90 km / h), it stops automatically in order to protect itself from the risks of deterioration.

The efficiency of a wind turbine is defined by:

  1. The nominal and maximum powers (in kW).
  2. The triggering threshold by the starting speed (in m / s).
  3. the average wind speed for its operation by the nominal speed of the generator (in m / s).
  4. The electricity produced by the average annual production (in kWh).

#3. How to Choose the Rooftop Wind Turbine?

When you make a final decision which is installing a wind turbine you have to ask yourself why I choose a rooftop wind rather than another model( ground home wind turbines )? 
The rooftop wind turbine can use the whole building height and roof area of the building. So it can capture more wind power but it saves a lot of space. This is why people prefer wind turbines to the surface from ground turbines.

Before installing a wind turbine on the roof, you need to know some basic things such :

1.Endurance of the roof

When the wind turbine is installed on the roof, the roof condition, such as structure, thickness, and building materials for the roof, must be checked. Of course, it must be ensured that the roof can withstand the weight of the turbine and the process of fastening to the surface to maintain the stability of the turbine without material losses, and this means that the roof load must be higher than the weight of the wind turbine and bear the fastening process.

2.Noise issue

3.Vibration issue

Turbine security matters. So the wind turbine whose vibration is lighter is the best option when thinking about the turbine model.
4.Tower cost issue

The height of the existing building must be considered, so the height of the tower can be relatively lower than the height on the floor. So the cost of the tower will be lower accordingly.

5. Appearance

In order to make the overall look better, the turbine must combine with the construction shape. There are factors that will affect the annual energy production of the wind turbine, including:

If the tower is longer( 25-60 ft.) , then the wind speed will be higher and so will the power output. And if the tower is shorter, then the wind speed will be lower and the same for energy output.

When the air density is lower, the wind strength will be weaker, the initial wind speed and the estimated wind speed will increase, and as a result, the annual energy output will be lower. On the contrary, when the air density is higher, the annual energy production will be significant.

It is a parameter that can measure wind speed and installation height. The best axle height can be chosen depending on it. If the wind shear value is too high, then the wind balance on the scanned area of the blade will be unbalanced, which will shorten the life of the blades and the structure to a shorter life span and security problems.

Wind turbine energy is the main factor affecting annual energy production. When the energy is greater, the production capacity will be more. On the contrary, when the energy is weaker, the output energy will be less.

The turbine can be installed on the ground or on the roof, which may also affect the output power. So the rooftop turbine can do better with the help of building height from the ground in the same condition.

  • Valid annual operating period:

As everyone knows, when the operating period is longer, the annual energy output will be more. By contrast, when the operating period is shorter, the output power will also be less.

Within the temperature range from -20 degrees to 50 degrees, wind turbines can work regularly. However, when the temperature is outside this range, it will affect the output energy. If the temperature is too high, the air density will be low, which reduces energy production. If the temperature is too low, the blades and other parts may be frozen, and the wind turbines will stop working.

The most important consideration you’ll make before deciding to  make a home wind turbine for your home is seen:

  1.  If you receive very high wind speeds.
  2. if you don t live in a densely populated area.
  3.  frequently don t  experience gale-force winds.

Then a wind turbine is the best solution

  • Average energy consumption 

On average, home wind turbines need a minimum amount of wind in order to operate. This varies based on the model, but the most clock in at around 2.6-3.5 mps(meter per second). The rated wind speeds for full energy production are generally around12 mps for standard units. If you live in an area that experiences a steady amount of wind, then a normal residential turbine is fine.

However, if you encounter regularly low wind speeds, you’ll need to look for models that have a lower threshold. One of the biggest contributing factors is the blades. Those with more blades, like 9 to 11, have more surface area, weight, and torque to keep the rotor spinning. This means they’ll still be able to operate in low-wind conditions while 3-blade models cannot.

When purchasing a home wind turbine, keep your eye out for these product specifications:

  • Starting wind speed
  • Cut-in speed
  • Rated wind speed
  • Safe wind speed

#4.Horizontal vs Vertical wind turbines

The horizontal wind turbine is the most employee. It offers high efficiency but is responsible for many nuisances nonnegligable. The vertical wind turbine is, for the time being, less widespread, but its performance equal to or even greater than that of a conventional wind turbine,
as well as its advantages of integration into the building, operation even with light wind and
occupancy of space makes it a solution very interesting, especially for domestic wind turbines.

The table below details each of these characteristics depending on the model, horizontal or vertical, of the wind turbine.
