Hybrid Wind Turbine Dali PowerTower

Wind- and Solar Solution Installed on a Wooden Tower

Hybrid wind turbine Dali PowerTower is a wind- and solar energy solution designed to maximise the efficiency of local power generation. This wind turbine and solar panels hybrid system is installed on a design- and patent-protected 12 metre Dali XII wooden tower. 

The Dali PowerTower is suitable for a variety of applications. It can provide electricity for a summer cottage, is suitable as a wind turbine for house, provide 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).


Generator & Blades

 

Hybrid wind turbine Dali PowerTower Performance 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. This wind turbine and solar panels hybrid system is equipped with the passive centrifugal variable pitch system with shock absorber for power control and electric brake system.

The blades are manufactured using RTM Light (Resin Transfer Moulding) technology based on the use of polyester resin with fibreglass. Wind turbine and solar panels hybrid system från INNOVENTUM is built with 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

INNOVENTUMs wind turbine and solar panels hybrid system has been designed to last 25+ years, even in the most adverse weather conditions, such as marine sites or high wind locations. This hybrid 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). The energy yield depends on the location, at 6 m/s our wind turbine and solar panels hybrid system Dali PowerTower produces 7800 kWh of wind energy per year (in addition to 2200 kWh of solar energy)

 


Anticorrosion Protection & Watertight Design

Dali PowerTower Performance is designed for coastal applications. All metal parts of the 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.

The wind turbine come in a waterproof enclosure to guarantee the watertightness. Besides the characteristics like corrosion protection, stainless steel hardware, the turbine features watertight housings seals.


Hybrid Wind Turbine Certification

The turbine in this wind turbine and solar panels hybrid system is certified according to all leading international certification systems

(which makes it eligible for all existing subsidies):

Microgeneration Certification Scheme (MCS) in the UK

AWEA certification in the USA

Class NK Certification in Japan


Solar Module Modularity

The quantity of solar modules and orientation angle can be adjusted to fit any energy requirements for your wind- and solar hybrid system. From 6 to 16 modules can be installed on the tower with or without extra ground screws.

 Installation Process

The Dali XII tower of the Dali PowerTower 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 (valid for Dali PowerTower Lite).

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.
