Proven: Variable diameter high windspeed turbine

Rated Output: - 3200W (3.2kW)

Voltages available: - 12V / 24V / 48V / 120V / 240V / 300V

Annual Output: - 3,200-5,000 kWh*

Rotor Diameter: - 3.5m - 0.5m (average 1.5m)

Hub Height: - 6.5m / 11m


* Based on an ideal site and average wind speed of 5m/s


Year average wind speed in our area in southern Sweden is approximately 7-8 m/s @ 45-75m


The patented Proven Flexible Blade System enables the turbine to generate power in light or strong winds. This unique system, a combination of innovative design and the latest techniques in advanced composite technology, allows the blades to bend and flex. As the wind gets stronger, the blades twist to reduce their aerodynamic efficiency. This lets the Proven Energy turbine maintain a high output even in the fiercest storms, unlike many turbines which need to stop generating power to protect themselves at high wind speeds. The blades also regulate their speed, preventing damage if the load from the turbine is disconnected through a power cut or electrical fault.

So far all is good - but now that you got the energy - what to do with it?

1) Grid Connection (developed world solution) 
Electricity is fed directly into your fuse box or distribution board, providing power to your premises. Any surplus electricity produced may be exported to the grid and sold to an electricity provider, Convenience and the opportunity to sell excess electricity have made this the most popular option.
Sweden: This is not an option here as our otherwise said to be front runners in green energy government, think that private people should not save money on energy - and thus do not allow for net debit on the always monopoly owned grid.

2) Battery Charging (third world solution) 
Energy produced by the turbine is stored in a large battery to provide a power supply. This is most beneficial in remote locations which are not connected to the grid.
Sweden: Since the governments position is as it is, we are forced to rely on this "third world" application which make our cost double - and force the use of loads of environmentally questionable battery banks.

3) Direct Heating (third world solution)
Energy produced by the turbine is directed to hot water tanks, storage heaters or under-floor heating, rather than providing electricity to feed into your power supply.
Sweden: We are also relying on this other possible "third world" application which make efficiency minimal with lots of wasted energy through dump loads.


Sweden is a third world country in it's approach to renewable energy when it comes to private enterprise.

- if we can't tax it - we won't allow it, that is the dogma.

The only concern is optimized monopoly profits and state taxes - period.

This is why everyone know the name of the Swedish Prime Minister, the Minister for finance, and our Minister for Enterprise and Energy, but who is in firm control over environmental issues?

no one knows - or what this guys office is busy doing...

Answer: Fredrik Reinfeldt, Anders Borg, Maud Olofsson and Andreas Carlgren... 

And the winner is: 

Mr. E.ON, Dr. Wulf H. Bernotat:
"At a time when public trust in the energy industry is low, 
trust in business is an essential prerequisite for our prosperity.¨

It's tough for the adoption and introduction of renewable energy when the government and state do not actively champion it. For most politicians green and renewable energy is not good policy, that is why the importance of global summits such as the G20 is quite crucial in the adoption of wind turbines and green technology.
