II - Why Noveol

7

1) Quality

1.a) Designed AND manufactured in France

The nov'turbine has been designed and developed by a team of motivated engineers convinced that the future of domestic wind generation belongs to silent, aesthetic, reliable and well-performing turbines.

We chose to keep both design and manufacture in France in order to better control the value chain and to react shortly if needed while reducing our carbon footprint.

The assembly of the nov'turbine takes place at our factory near Poitiers.

1.b) Up to 10 years warranty

Our warranty is among the longest in the world! Indeed the nov'turbines are guaranteed for 5 years, extensible to 8 or 10 years. It is our way to prove that we are confident regarding the quality, the performance and the reliability of our products.

1.c) Service life of 30 years minimum

Noveol components come from the best manufacturers in the world, especially our ball bearing provided by SKF World-number-one and our inverter from Power One, currently World number two, etc.

Furthermore, in order to ensure a long life service, we chose to limit the number of wear parts to the ball bearing and the generator only, while increasing their sizes. The generator is therefore maintenance-free and the ball bearings (bigger than large truck ones!) are lubricated by your installers; that way, you are sure to always have a well-performing wind turbine.

8

1.d) Accredited installers

Not everyone can install a nov'turbine. Our distributors network, covering the whole France, Belgium and soon the UK, had to follow a specialised training from our office and had to receive our certification before being authorised to sell the nov'turbine.

1.e) Monitoring and after-sales service

The nov'turbine is equipped with sensors that enable to monitor its production, behaviour and good functioning. In case of problem, we receive the information and the closest installers can then come to your site and fix it.

Furthermore, we carry out steady controls and systematic monitoring of all our installations.

2) Reliability

2.a) Site assessment for wind energy potential

We systematically recommend going through a site assessment prior to installing a wind turbine in order to evaluate the potential for wind power generation. This study will measure the average wind speed at the location chosen for the installation, which determines the average Annual Energy Production forecast. This is a key step before investing in a wind turbine!

2.b) Safety break

Most of the wind turbines are usually only equipped with a unique “electromagnetic break”, which short-circuits the generator in case of problem. However this operation tends to heat the components, which reduces components life span but can also damage the whole equipment. The nov’turbine therefore has two breaking systems to insure a complete safety, among which, a mechanical break, known as “failsafe A”. Beyond being a requirement from the current IEC* standard, the break insures rotational speed control even if the turbine gets disconnected from the grid or if the system turns out to be out-of-order.

*International Electro-technical Commission 61400-2-2006: Design requirements for small wind turbines

9

2.c) Compliance with standards

Small Wind Systems must meet the IEC 61400-2 standard, requiring a number of safety and performance criteria. From the start, the nov’turbine has been designed according to this standard. Be aware though, despite the existing IEC 61400-2, a certain number of wind turbines and manufacturers still do not respect this standard. The reason for this mainly is because, to our knowledge, no organisations are able to deliver it in France. Be careful then!

2.d) Real time surveillance

Thanks to an electronic control card, the nov’turbine is monitored in real time. In case of a problem, we are immediately informed and can therefore, fix your turbine shortly; one more key element again that ranks the nov’turbine among the most reliable wind turbines.

Performance

Instant power is function of wind speed. As soon as a there is a breath of air (3m/s), the nov'turbine begins to rotate and generates more and more power until the wind is as fast as 15 m/s. If the wind goes stronger, the control card automatically regulates the rotation speed, enabling a complete safety. After 20 m/s, the turbine is automatically stopped.

The annual energy production of the nov'turbine can be estimated from the wind speed at the exact location of the installation and by using the graphs below. The graphs are given for obstacle-free space with a Weibull coefficient of 2.

Regulation

The control of the nov'turbine is ensured by an electronic card.

Its role is to protect the turbine, managing several break modes and evacuating heat due to overproduction. In order to maximize the efficiency of the wind power, it has been fitted with an internal controller that automatically adjust the rotational speed of the turbine.

20

Generator

The mechanical energy is converted into electricity thanks to the permanent magnet generator. This permanent magnet has multiple key advantages, one being that it doesn't require any maintenance. The generator is directly driven by the blades, without any speed multiplier, which allows again less maintenance.

21

Inverter

The inverter converts direct tension into alternative tension. When the inverter is parallel to the electricity provider network, the alternative current generated by the inverter circulates inside the local domestic network. The wind power may thus feed all the electric devices.

If the electricity generated by the turbine is not sufficient, the surplus will come from the grid.

IV - UK REGULATION

26

Height and local-planning permission

Small wind energy installations require planning permission and local consultation with relevant stakeholders, such as neighbours. Deciding factors include environmental considerations, access to the site, noise and visual effect. Getting planning permission can be a barrier to householders wishing to install microgeneration technologies.

In England and Scotland, changes to permitted development rights (PDR) were introduced on 6 th April 08 and 12th March 09 but excluded wind turbines, for reasons of possible noise and amenity issues. Last year the Department of Communities and Local Government (DCLG) consulted on proposals to extend permitted development rights to various categories of renewable energy technology, including domestic wind turbines. The consultation suggested at 45 decibel noise limit for permitted planning (PDR).

Permitted Development Rights should remove the requirement to submit a planning application to the local planning authority for developments meeting specified conditions, saving costs and time. But in the case of wind turbines, potential impacts such as noise, vibration, appearance and public safety all need to be carefully addressed.

The Statutory Instrument granting permitted development rights for domestic wind turbines has been laid before Parliament and will come into force on 1st December 2011. Until permitted development rights for domestic wind turbines are introduced, there is no alternative but for a potential generator to work closely with their local planning authority to seek planning consent. Such planning decisions fall within the remit of local planning departments, and not DECC.

27

Minimum distance

Minimal distances have to be respected, such as between the nov’turbine and your house or the limit of your property.

28

Noise

The eventual noise caused by a wind turbine should not exceed a certain level of decibels. In the United Kingdom, a small Wind Turbine should not produce more than 10dB above the wind noise (ie. ETSU R97, BS4212 and BWEA_SWT_Standard_Feb2008).

Underpinning

It consists in making a reinforced concrete block adjusted to the height of the selected mast and the type of soil where the nov’turbine is be installed.

Anchorage shanks fixed into the concrete will help to anchor the mast to the ground.

Noveol supplies shanks and anchor bolt. Note that an investigation regarding the nature of the soil is mandatory before each installation. It will help to determine the dimension of the block.

The grounding, following standards prevailing locally, will also be realised during this part of the process.

Only professionals authorised or certified by Noveol should execute underpinning (therefore please insure that installers have received such authorisation beforehand).

Assembly

Once the trench is done and the concrete dry, all the parts of the nov’turbine (delivered on site) will be assembled.

The installer is responsible for this part of the work. Depending on the ground configuration, the difficulty to access it and the type of mast selected, they will connect on the ground firstly, then a crane will lift the nov’turbine, turn it vertically and fix it to the anchor shanks,

Or thanks to a jack, will lift the articulated mast to erect the nov’turbine in the right position.

Only professionals authorised or certified by Noveol should proceed here (therefore please insure that installers have received such authorisation beforehand).

Electrical connexions

Only professionals authorised or certified by Noveol should make the electrical connexions (therefore please insure that installers have received such authorisation beforehand).

Option 1: Set-up and delta connexion in the technical area

The installer assembles the electrical equipments in a suitable/protected place chosen by the customer.

Option 2: Set-up and delta connexion in the technical switchgear cubicle

In the case where a customer does not have the right location for electrical equipments a switchgear cubicle will be installed.

37

If the electricity produced is for self-consumption, the installer, following the simplified functional scheme below, must do the set-up and the delta connexion:

N.B: To transport the energy in the best possible conditions, it is better that most of the distance between the nov’turbine and the place where most of the electricity will be used, is three-phase driven. Therefore, it is preferable to install the switchgear cubicle as close as possible of the place where the energy is meant to be delivered.
