SWIFT™ Rooftop Wind Energy System

As part of its mission to provide accessible renewable technologies and reduce fuel

poverty, Renewable Devices Swift Turbines has designed and manufactured the world’s

first silent, rooftop-mountable wind turbine, capable of providing a cost-effective

renewable energy source for domestic, community and industrial use. The SWIFT™ can

be grid-connected for embedded power generation, installed with battery bank for off-

grid stand-alone applications or linked to an immersion water heating system. Theemphasis of the design process has focused on safety, reliability and ease of operation,

alongside the high-performance of this innovative system. Unique technologies have

been developed, leading to the filing of five international patents, which allow the

SWIFT™ Rooftop Wind Energy System to offer:

Universal application

Silent, vibration-free rooftop operation

Simple installation

Safe, efficient & autonomous operation without maintenance

Visually appealing design which is planning compliant

Environmentally sustainable “harm neutral” design

Sophisticated maximum power point tracking electronic controlsystem

The SWIFT™ turbine is mounted on a bespoke aluminium mast with a minimum blade-

roof clearance of approximately 0.5 metres. It is usually optimally mounted at thehighest point of a roof in a position which benefits from prevailing wind, but will

work effectively in almost any location. The SWIFT™ is designed to be aesthetically

pleasing and is planning legislation compliant.

To ensure minimal transmission of oscillations

from turbine to building, the SWIFT™ turbine

mounting brackets incorporate damping

systems designed to absorb a wide range of

frequencies. The patented ring diffuser

minimises turbine noise by preventing the

creation of turbulent vortices at the blade tip.

In addition the five bladed design allows for a

slower speed of rotation to further reduce

noise, making the SWIFT™ Rooftop Wind

Energy System the quietest wind system

currently available.



The SWIFT™ has a unique over-power regulation mechanism to control rotation speedand maintain system integrity and safety in high winds. This consists of a patentedtwin-vane progressive mechanical furling mechanism coupled with a sophisticatedelectronic control system, the world’s first to utilise maximum power point tracking(MPPT). The optimum amount of power can be taken from the turbine under all windand loading conditions - without stalling, representing a step change in the accurateand safe control of small wind turbines. The controller also contains a fail-safe system,allowing the turbine to safely retain structural integrity in extreme weatherconditions.

Benefits

The benefits of generating your own clean energy are both financial and

environmental. The SWIFT ™ Rooftop Wind Energy System is designed to be simply

and easily connected to your local electricity grid, so that the energy you generate is

offset directly against your electricity consumption - thus directly saving you money.In addition the SWIFT™ is eligible for grants to reduce the initial cost of installation and

the sale of ROC’s or ‘Renewables Obligation Certificates’ will bring in further revenue.

Overall it can be expected that the SWIFT™ will generate up to 4,000kWh per year

(dependant upon the wind resource at a particular site) providing a net financial

benefit of up to £440 per year.

In environmental terms, each unit of electricity generated from a SWIFT™ Rooftop

Wind Energy System displaces one unit generated from fossil fuels, with the added

benefit that the electricity is consumed on-site, thus negating losses from

transmission. This amounts to a displacement of approximately 1.6 tonnes of CO2

per

year – a significant environmental contribution.

Development Status

The development phase of the SWIFT™ is

now complete. Extensive testing has

been carried out on both prototype and

pre-production units to ensure the

systems safe and efficient operation.

Manufacture has commenced of

production models and these are

currently being installed in diverse

locations across the UK. The SWIFT™

Rooftop Wind Energy System will be in



Both the turbine and electronic control

system have been designed using cutting-

edge computer analysis and design

technology.

The SWIFT ™ Rooftop Wind Energy System is

the first rooftop-mountable wind turbinesystem in the UK to be officially accredited

for grant funding by the Energy Saving

Trust.
