A classic horizontal axis wind turbine has the appearance of a large fan, placed on top of a supporting pole, often when it's small is equipped with an helm for the orientation to the wind, this part, if low quality, creates vibrations and can be very noisy. The generator of the machine is parallel to the [...]
The Etneo horizontal axis wind turbine is realized with rotors provided with aerodynamic curves able to pick up the wind from the rear and able of accelerating its speed, thus increasing the production capacity. The turbine does not have the rudder thus minimizing vibration and noise, exploit the aerodynamic and the sail for the turbine orientation [...]
A classic vertical axis wind turbine has the blades placed vertically in a ring around the axis of rotation, it may be of the Savonius type small and with low efficiency, or the Darrieus type with larger blades of various shapes and sizes with considerable weights and sometimes difficult to start with light winds. The efficiency [...]
The Etneo vertical axis wind turbine is also called hybrid because on the same axis mounts: the Savonius rotor oriented on the 4 cardinal points to start the rotation with the winds, the Darrieus rotor with three aerodynamic profile curved blades to increase efficiency and production capacity with moderate and strong winds. The 61400-2 certifications made [...]
The current legislation considers the installation of individual wind turbines on existing buildings with a height less than 1.5m and a diameter of less than 1m as normal activity for free building and therefore are subject only to inform the authorized municipality. In the case of wind farms different form the above ones, with a [...]
For wind turbines with power ratings from 1 to 5kW the costs are, more or less, in the order of 5 to 6,000 € / kW for the installed product. However, there are many variables related to the installation location, the type of post needed for land rather than a roof building, to the devices [...]
Etneo wind generators available for on-grid installations are the horizontal model A018 with 1,4kW, using ABB 3kW inverter and wind interface and the vertical model DS3000 with 3kW using ABB 3-3,6kW inverter. The A018 turbine is provided with 1,75mt pole and a control box to connect to the inverter while the DS3000 model comes with a control [...]
The monitoring of energy consumption is a very useful practice in order to understand the functioning of the electricity, very important component in the life of every thinking human being. This understanding helps people to manage the electrical appliances in their home, office, in general allows for positive action in a reduction of such consumption. See [...]
The Etneo proposal is very simple and based on two types of products: monitoring via display with web option ready or monitoring only on the web. Let me explain better: Ensemble is the Etneo color display used to show real-time data of current fuel consumption and cumulative, graphics speedometer tells you how you consume instantly, [...]
A storage system is a set of equipment that allows you to store energy, generated from renewable sources, in a battery bank and then use it at any time. There are several storage systems with various working way and different products, listed below are some characteristics of those provided by Etneo Italy: Etneo storage for [...]
