Tax Benefits

Private

Any private customer purchasing our vertical axis mini wind turbine can have a 50% tax deduction of the expenditure within a limit of € 96.000 (VAT included) in 10 years.
For instance, with a € 60.000 expenditure, € 30.000 are deductible, that is € 3.000 each year for 10 years. Everything can be indicated in the tax declaration or in the 730 model (individual tax return), as long as the payment is only done via bank transfer. Such a deduction is allowed on the basis of art. 16-bis letter h) of the TUIR (Consolidated Text of the Laws on Income Tax), as its contemplated in case of energy-saving works.

Company

For a company the purchase price of the wind turbine is ordinarily annually deductible from the business income, with the amortisation procedure. Moreover, the cost is further deductible via the “super amortisation” that allows a further 30% deduction of the cost, related only to the components of the wind turbine. That’s why the company, depending on the installed wind turbine, will estimate the components with the aim of correctly calculating the precise amount of the incremental tax deduction.

FAQ

How big is the ENESSERE Hercules Wind Turbine?

ENESSERE Hercules Wind Turbine is 8,85 m tall. This is the suggested height to comply with the golden ratio between rotor and tower. However, it can be increased based on a customer’s specific demands, in order to exploit stronger and more stable wind currents. The maximum diameter of the rotor is 2,68 m.

Does ENESSERE Hercules Wind Turbine need protection against thunder strikes?

There is a grounding system for the controller and turbine that is necessary to protect the electronic components. Moreover, the turbine features the proper over-voltage arresters. We’re however testing new innovative solutions to increase security even further.

What happens if there's a blackout from the company that provides me with electricity?

In this case the inverter cuts the supply of electricity to the grid until it’s safe to start back up again. At the same time, an internal hydraulic brake stops the rotation of the wings for safety reasons.

How much energy can the ENESSERE Hercules Wind Turbine generate in one year?

The output depends on how windy the site is and on the type of wind.

Following the Weibull Distribution chart, with an average wind speed of 6 m/s and k=2. ENESSERE Hercules Wind Turbine generates 3.700 kWh.

Which is the peak power of the ENESSERE Hercules Wind Turbine?

Peak power on wind speed between 18-20 m/s is about 3 KW. These figures are indicative and might adjust considerably based on the type of wind in the installation area, its consistency and nature. Generally with more humid wind gusts such as sea breeze, or the winds that precede snowfall, the generated output is considerably higher with the same wind speed.

How long does it take to start up? How does it brake?

The start up (or ignition) requires a constant 3,0-4,0 m/sec wind: the wind turbine starts rotating anti-clockwise and increases constantly until wind speed reaches 18-20 m/sec – that’s when the wind turbine reaches its max operating level. If it goes over this level, the controller brakes and stops the wind turbine in order to guarantee its total safety of use.

The user can manage the controller touch interface to establish three different modes that place a limit to the rotations beyond which the turbine slows down: Adagio up to 80 rpm, Andante up to 140 rpm and Vivace up to 200 rpm, in order to fully enjoy the turbine.

How are noise and vibration levels?

ENESSERE Hercules Wind Turbine is totally silent. The noise emitted at its max rotation speed, 200 rpm, is 51 dB that is much lower than 60 dB, which is considered annoying to the human ear. In other words, wind noise is always higher than the noise generated by the rotor.

Is it possible to install multiple ENESSERE Hercules turbines close to one another?

Yes, it’s possible to install multiple ENESSERE Hercules turbines, provided that the minimum distance between them is at least 8 meters. If not, there might be service interferences on the rotors. Anyway, it is advised to use a single inverter and controller on each ENESSERE Hercules Wind Turbine.

What is the lifetime of an ENESSERE Hercules Wind Turbine?

If you always conduct the pre-planned maintenance activities, an ENESSERE Hercules Wind Turbine will last at least 20 years. The only components that might wear over time are the three bearings, the surface treatment of the wings and the potential degradation of the internal generator.

What are the safety features of the ENESSERE Hercules Wind Turbine?

ENESSERE Hercules Wind Turbine has been designed in order not to go beyond the 200 rpm when generating energy. This is how his rotation range can remain below the structural weakness threshold, increasing its safety and life cycle. The controller constantly monitors it, and its braking and stopping phases are due to both the internal alternator and the possible use of the hydraulic brake.

Is ENESSERE Hercules Wind Turbine accredited?

ENESSERE Hercules Wind Turbine has been designed in accordance to the EC directive for the EC marking and with EN 1090-1 and IEC 61400-2.

What are the next improvements you want to introduce?

We’re constantly working to improve the maintenance and life cycle of the wooden wings by experimenting new paints and drying processes.

Moreover, the software in our controller is constantly improving so that the wind turbine can be self-taught in learning wind patterns over time and can re-elaborate data depending on how windy a specific site is by using the most performing torque curve.

This process goes hand in hand with our intention of remotely managing the wind turbine via web. The goal is to create a turbine that is in itself a weather and pollution info hub. We’re basically moving in innovation areas of the Internet of Things.

Are birds and issue for the ENESSERE Hercules Wind Turbine?

It is highly unlikely that the activity of our wind turbine interferes with birds; both because of its height from the ground (only 9 m) and its limited surface compared to vertical axis systems, so it’s more visible to animals.

What other tools does the ENESSERE Hercules Wind Turbine need to work?

The installation requires a foundation plinth, which itself requires a minor excavation operation. 2×2 and about 1,5m deep. Moreover, if there are no pipelines, a small channel must be built to connect the wind turbine to the controller. Finally, if the power is fed into the grid, it is necessary to have an inverter approved in accordance to various countries regulations.

Can the ENESSERE Hercules Wind Turbine be used as a "stand alone" or does it always have to be connected to the grid?

Yes, it can be used as a “stand alone” with the help of batteries that store energy. The cooperation with a prestigious Tesla distributor in Italy made use choose Powerwall Tesla as a storage solution.

Can I install ENESSERE Hercules Wind Turbine on a roof?

Even though it’s been conceived to be installed on the ground, it is possible to evaluate other installations for the ENESSERE Hercules Wind Turbine on reinforced concrete structures, provided that a thorough examination is conducted on how much weight they can carry and potentially a customization of the installation.

Can the ENESSERE Hercules Wind Turbine be installed in marine environments?

Absolutely, yes. All paints, coatings, external finishes and surfaces of our wind turbines have been designed to resist in marine or brackish environments.

What are the phases that are conducted before the installation?

Initially it’s useful to conduct a feasibility study by examining pictures or layouts of the site where the installation will take place. Then it is advised to conduct an inspection with our technicians in-situ that precedes the installation project itself. Bureaucracy provides the forwarding of a request to the local administration, which has 30 days to issue a statement before “tacit consent” is triggered. It will then be possible to proceed with the excavation and creation of the plinth and, after 10 days, with the installation of the turbine. In a matter of a few hours our team will be able to hoist the tower, position the rotor and calibrate the wings. Then, once it’s tested, our wind turbine will be ready for use.

Where are turbines made?

ENESSERE Hercules Wind Turbine is created and assembled at our production facility in Brendola, Vicenza and other labs in the Vicenza province.

What kind of maintenance does the ENESSERE Hercules Wind Turbine need?

Normally it does not need any specific periodic maintenance activity. The maintenance plan however plans a series of checkups in the first 12 months of the turbine’s life, and then it is advised to conduct a yearly checkup. That’s why we always suggest subscribing to an extension of the basic warranty period (2 years) Please check out the specific section on the website.

How long does the warranty period last?

We do offer a 2-year basic warranty period on spare parts and product. By subscribing to the ENESSERE customer assistance we offer and extension of the “all inclusive” service for the maintenance of the product over time.

Can I recycle the ENESSERE Hercules Wind Turbine?

When ENESSERE Hercules Wind Turbine has reached the end of its life cycle it must be brought to a recycling center as the metal in the turbine and the electronics can be reused. The tower can instead be used for a new turbine. Our company can regenerate wings so they can be used again.

Are there any legal requirements for the installation of the ENESSERE Hercules Wind Turbine?

Since the height of the ENESSERE Hercules Wind Turbine is less that 15 meters and the installed capacity is lower than 60 kW, it does not fall under the specific category of the “Mini Wind Generator Systems”. It is still however necessary to consult the local administration of the place where you intend to install the wind turbine to make sure that there are no municipal or regional laws that impose restrictions and/or other regulations. In most cases the only obligation that applies is the issue of a SCIA indicating the start date of the installation, for which the tacit consent applies: 30 days after the official submission, if the local administration hasn’t issued anything, the installation can begin. Should the system be connected to the grid via the “Conto Energia” (“Energy Account”), the GSE (Italian National Grid Operator) process will have to be initiated.

What is the nominal power of the ENESSERE Hercules Wind Turbine?

The nominal power is 3 kW. The production will peak at about 3,2 kW, which are reached if the wind blows constantly at 18-20 m/s.

At what speed does the ENESSERE Hercules Wind Turbine enter full capacity?
