Domestic wind power plant

The installation of a domestic wind turbine can be a future-oriented investment in these times of ever-increasing electricity prices, makes it possible to become partially independent of the power utilities. With backyard wind turbines we can produce electricity to power a television, fridge, computer, gate, but also an electric heating system for a building. Such possibilities are offered by small wind turbines from 3-5kW.

There are also domestic wind turbines generating 10-50kW, which allow the surplus energy to be sold back to the grid for additional profits.

In addition a domestic wind turbine brings a number of other benefits:

The ability to sell surplus energy to an on-grid utility
The possibility of storing excess electricity (batteries). Particularly important in facilities that have frequent power outages when it is important to keep key equipment running.
Quiet operation - domestic wind turbines do not emit significant noise, so they will not disturb householders or neighbouring residents

Environmentally friendly - the wind turbine is regarded as a renewable energy source and does not emit carbon dioxide, smog or other pollutants.
Subsidies for domestic wind power plants - in order to make the cost of investing in a domestic wind power plant lower, in Poland we can take advantage of various subsidies, preferential loans and credits. This makes installation more cost-effective and pays for itself more quickly.

Ways of installing a wind power plant:

Currently, the conditions for the construction of small wind power plants are regulated by the Wind Power Investment Act of 20 May 2016. A micro-installation is an installation with a total capacity of no more than 40kW. In the case of the construction of a small wind power plant that does not exceed 40-50kW, it is not subject to the localisation procedure.

The installation of such an installation can be done in 3 ways:

A power plant permanently connected to the ground- it is necessary to obtain a building permit for a mast mounted to the foundations. Within the meaning of the Act, this mast is a construction object requiring the submission of an appropriate application for planning permission. The application must be accompanied by a construction project and a declaration of the right to dispose of the property for construction purposes.
Power plants not permanently connected to the ground - in the event that the foot of the mast is not installed in the foundation, but supported by guy ropes, the investor is only required to submit notification of the intention to erect a power plant to the office or district authorities. If the authority does not raise an objection within 30 days, the installation may begin.
Building-mounted power plants - installation within 3 metres around the building does not require any permits, while for those above 3 metres above the building contour (roof ground), a notification of construction is required from the building supervisory authorities.

For structures not permanently connected to the ground (e.g. towers with rope lashings), no permit is required. It is assumed that non-permanent structures are not building structures. Therefore, when erecting a wind turbine without any permits, it is best to do so on such a structure. Below are visualisations of such a solution.
