rooftop wind turbineA home wind turbine is in a range of nominal powers between 0.1 and 36 kW. The machine consists of a rotor, with 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.

Varied efficiency in the residential sector

The production capacity of a domestic 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.

How to Choose the Rooftop Wind Turbine?


When you want to install a wind turbine on the roof, you need to know why you prefer the wind turbine to the roof and how to choose the wind turbine on the roof. 

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 clarify and know some basic things

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 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:


Average annual wind speed:



It is an important factor in determining annual energy production. In general, if the wind speed is higher, the rotor speed will become faster, so the output power will increase. On the contrary, when the wind speed is lower, the rotor will become slower.

Height of tower:


If the tower is longer, 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.


Air density:



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.

Wind shear value:


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 strength :



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.

Turbine Height:


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.

External temperature:



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.
