Small Scale Wind
Turbine Dali
Installed on a Wooden Tower
Small scale wind turbine Dali is a fully integrated wind energy solution designed to yield maximum energy at a given rotor diameter. It is installed on a design- and patent-protected 12 metre Dali XII wooden tower.
The Dali is a residential wind turbine, suitable for a variety of applications. It can provide electricity for a summer cottage or a house, deliver heating for hot water, power lights and electronic equipment - either connected to the grid or in remote locations, e.g., replacing a diesel generator (with a suitable battery backup). The Dali can be installed either stand-alone or on the roof as it works quietly.
Generator & Blades of the Dali
Small scale wind turbine Dali has a permanent magnet generator with a great number of poles to reduce the rated speed to 250 rpm. This decreased rotation speed considerably reduces materials wear and noise. A low cut-in speed enables it to work with 3m/s wind speeds. Equipped with the passive tilt system, that safely transfer the turbine in helicopter position in strong wind to limit the rotor RPM and still continue to produce energy even at high wind speed.
The blades are manufactured using RTM Light (Resin Transfer Moulding) technology based on the use of polyester resin with fibreglass. This results in lightweight components with greater mechanical resistance. Using this manufacturing process based on the most advanced technology used in utility scale wind turbines, the weight obtained is less than half of common blades, providing enhanced mechanical resistance.
Durability & Performance
Small scale wind turbine Dali has been designed to last 25+ years, even in the most adverse weather conditions, such as marine sites or high wind locations.This residential wind turbine will operate normally even at wind gusts up to 60 m/s, 216 km/h or 135 mph (Class I winds according IEC 61400-2 standard). These winds are classified as hurricanes. The well-built and rugged design will allow the turbine to withstand mechanical stresses caused by sustained average high winds such as certain locations with 9 m/s (32 km/h or 20 mph).

Anticorrosion Protection & Watertight Design
Our small scale wind turbine Dali is designed for coastal applications. All metal parts of this residential wind turbine have been coated with marine grade powder coat for ensuring superior protection from the environment. A wooden tower works better in the seaside environment compared to a steel tower, as the former is not susceptible to corrosion due to humidity.
This small scale wind turbine comes in a waterproof enclosure to guarantee the watertightness. Besides the characteristics like corrosion protection, stainless steel hardware, the turbine features watertight housings seals.
Certification
The Dali small wind turbine is certified according to the leading international certification systems
(which makes it eligible for subsidies in the respective markets):
Microgeneration Certification Scheme (MCS) in the UK
AWEA certification in the USA
Class NK Certification in Japan

Installation Process of Small Wind Turbine Dali
The Dali XII tower of the Dali Performance solution has a number of practical advantages:
- Easy transportation thanks to the modular design and small packing volume.
- Silent operation of the wind turbine thanks to noise reduction by the wooden elements and multi-leg design.
- Possibility to erect the tower without a crane - using electrical or manual winch - which is particularly advantageous in remote locations.
In most cases we use screw foundation for our solutions, which is an environmentally friendly alternative to the concrete foundation. Screw foundations require no soil movement and offer considerable water and material savings. If the installation site is rocky, we propose a steel rod foundation that is drilled directly into the bedrock. In cases when concrete foundation is the only alternative, the amount of concrete required for the Dali XII tower is 7 times less compared to a classic tubular steel tower of the same height. This is achieved thanks to the multi-leg design of the wooden tower.
