When we cannot make good use of the sun because our house is not well exposed, we can think of the mini wind turbine against expensive bills: installing a small turbine on the roof of our house or even on our balcony is not an economic solution in itself, but in the long run it becomes
He is about to end up run over, his mother saves him
even the mini wind against the expensive bills: if we cannot take advantage of the photovoltaic on the roof or from the balcony because we have little sun, we can produce electricity with a small wind turbine, a mini turbine to be placed similarly on the roof or on the balcony.
Mini because small, but not insignificant: installing a mini wind turbine on our roof or even on our balcony if it cannot allow us to disconnect from the grid but it can help. A small turbine, when installed in a windy area, really cuts your bills.
Technology is indeed greatly improved: current machines now have most of the components and devices that have made the major wind power successful, with important results in terms of reliability and performance. So mini yes, but not for efficiency.

The mini wind turbine for home use
How do you explain Anev (National Association of Wind Energy), in the international context it is intended to classify wind turbines as mini wind turbines up to 100 kW of power, even if formally according to the legislation IEC 61400-2 they are part of this category that generate a power generally lower than 50-60 kW.
For a private home, the right sizes are those with one rated power between 1 and 6 kW that no, they are not enough to make a private home independent from the network, considering the current average consumption, but they are a help, which we all really need at this particular moment.
How to install a mini wind power plant to increase its efficiency
Just as a balcony photovoltaic system must be installed in such a way as to collect as much solar energy as possible, so a mini wind turbine must be placed with care in order to make the most of exposure to the wind.

For wind power, in particular, the balconies are less suitable on paper, being protected by the walls of the building, but here too there is plan B: you can in fact opt for a vertical axis wind power plant, which has the ability to make better use of the winds of lesser intensity, as well as occupy less space.
Mini wind: how much it costs
Let's say it straight away, the mini wind turbine is not an initially very economical solution as the balcony photovoltaic is not. Taking a tour on the net, in fact, you realize that the costs are not exactly contained, especially if you aim for the horizontal system for the roof, over generally more wind circulates.
The classic horizontal wind turbines in fact have prices between the 1.000 and the 2.000 euro for a production between 1 and 3 kW, to which it is necessary to add the costs for the installation itself. However, there are "urban" solutions, consisting of wind turbines arranged on a wall, called "mini-wind turbine", Which could be used" in sharing ".

If, on the other hand, you prefer to turn to balcony solutions, perhaps because you live in a condominium or because the building is not particularly exposed to the wind in any case, you must opt for a vertical axis system, whose costs are much lower. even 200 euros, but for productions of 0,5 kW (peak).
Of course, it is right and proper to do the accounts in hand on a case-by-case basis, but let's never forget that continuing to use fossil energy sources is a strategy that is doomed to fail in any case.
