Dalifant

Dalifant farm-based system for small-scale wind power with wooden towers

Dalifant is a farm-based wind turbine that generates electricity for homes, farms, and businesses. Its unique design consists of a 20-meter wooden tower and an 11-kW turbine with a large swept area of 133 m². This combination ensures high wind energy production, and the wood helps absorb vibrations and noise from the wind turbine. The energy output of a small-scale wind turbine like Dalifant is equivalent to 60 square meters of solar panels, with the advantage that a farm-based wind turbine generates power around the clock, year-round.

"Just seeing the wind turbine gives you such a sense of power—and think of all the power it feeds into the grid!"

Gustav and Marie Mandelmann are incredibly pleased with their Dalifant, as is clearly evident in thissegmentthat aired on TV4. Since 2015, the wind turbine—along with the solar panels on their roof—has generated a fantastic amount of clean, sustainable electricity. On this page, you can view the total energy production in real time.

Reliability & Security

The wind turbine on our Dalifant has undergone extensive international testing to ensure quality and safety. It has been approved under the UK’s Microgeneration Certification Scheme (MCS), has been rigorously tested in the United States, and holds Danish HBO certification.

The wind turbine has three different safety systems that provide protection during extreme wind conditions 

  • Passive aerodynamics, in which the airflow separates from the blade at high speeds, thereby limiting the power output.
  • Mechanical brake.
  • Centrifugal-activated blade-tip brakes.

Resource Efficiency

A complete Dalifant wind turbine, including ground screw foundation recycled steel, weighs four metric tons and produces 38,000 kWh per year at an average wind speed of 6 m/s.

A typical large-scale 3-MW wind turbine weighs 2,565 metric tons, including a concrete foundation weighing 1,250 metric tons. This foundation cannot be recycled and will remain in the ground for at least 100,000 years. Such a wind turbine produces 4,900,000 kWh per year at the same average wind speed.

Compared to the resources required for the DALIFANT small-scale wind turbine, the resource efficiency is 1.9 kWh per kilogram of material.

The DALIFANT farm’s resource efficiency is thus 9.5 kWh per kilogram of material. This makes DALIFANT five times more resource-efficient than a typical 3-MW large-scale wind turbine.

The Swedish National Property Board's Performance

Our Dalifant is one of the most efficient wind turbines for small-scale wind power plants in its size class. For the generator to produce energy, the wind’s kinetic energy must first be captured by the rotor blades. Longer blades provide a larger swept area, thereby increasing energy production.

The wind turbine has a swept area of 133 m², which is twice as large as that of competing turbines with the same generator size (10–11 kW). The larger swept area enables energy production comparable to that of larger generators: 38,000 kWh/year at an average wind speed of 6 m/s. The wind turbine is optimized for the wind conditions prevailing at a height of 20 meters.

The Swedish National Property Board's noise level

When we plan our wind turbines, we strive to minimize their impact on the surrounding environment. An important factor in this is noise level. Our turbine is one of the quietest wind turbines on the market and has a noise level of 40 dB(A) at a distance of 100 meters—which is equivalent to the noise level in a quiet library.

This low noise level is a crucial factor in building permit applications, as many municipalities and environmental agencies use 40 dB(A) as a guideline to ensure that nearby residents are not adversely affected. By staying within this limit, we simplify the process and increase the chances of smooth approval.

Real-Time Wind Energy

Our Dalifant can be combined with solar panels. Below, you can see the energy production from the small-scale wind turbine in real time from an installation in Skåne. At this installation, the solar panels’ energy production (17 kW) has been recorded since May 1, 2015, while the DALIFANT’s energy production (11 kW) has been recorded since September 1, 2015.
