A mini wind turbine for the garden: what you need to know
Interest in a mini wind turbine for the garden is growing. This technology is used to produce heat and electricity yourself. For some people, having a private wind turbine in the garden is worth it. If you are careful when purchasing and choosing the location, you can benefit from it.
Is a mini wind turbine worth it for the garden?
Electricity and heat cause a lot of expenses. There is currently a fear that prices will continue to rise. If you would like to become a little less dependent on energy suppliers, you can generate your own electricity with a mini wind turbine in the garden.
The sun only shines during the day while the wind also blows at night. A small wind turbine can cover part of the electricity requirement and is therefore the ideal supplement The solar power system can be a small wind turbine if your property is suitable for it to set up. The most important question before buying a wind turbine is: Is there enough wind blowing locally? Experts recommend a wind force of at least 3 to 5. The weather service's wind map provides a rough estimate. A mast height of twelve meters or more is recommended.
How high is the performance?
For small wind turbines, the output is up to a maximum of 100 kW:
- Micro wind system: 0 to 5 kW
- Mini wind system: 5 to 30 kW
- Medium wind system: 30 to 100 kW
Electricity can be generated using relatively simple means. Although the current strength is only...
Micro wind turbines are primarily used for homes. For small and micro wind turbines, the diameter of the rotor head is one to four meters. In general, the higher the output, the more electricity the system can produce. Surrounding buildings, trees or other things are a hindrance.
How does the small wind turbine work?
The small wind turbine works in the same way as a large wind turbine: the energy obtained from the wind is converted into electricity. This is done by a rotor that is powered by the blades and rotates when the wind blows. The kinetic energy enters the generator via a gearbox and a drive shaft and is converted here Direct current and for slightly larger systems using an inverter in alternating current with 220 volts converted.
Is a permit necessary?
When it comes to approval for a small wind turbine, different regulations apply in the federal states. In most cases, no special permit is required for systems under ten meters high. In some cases, as in Berlin, Bremen and Lower Saxony, approval must be obtained from the building authority. The location, such as a nature reserve, is also crucial. In a rented apartment, the landlord has a say.
Many homeowners want to supply themselves with electricity. In addition to solar energy, this is also possible with wind energy with a mini wind turbine in the garden. The most important success factor is installation in a location with strong winds.
