Bjerga Engineering

We have everything you need for wind energy in the class of 300 W to 20kW with vertical axis wind turbines.
The vertical axis or "VAWT" type of wind turbines are very suitable  for homeuse and villas to complement or to completly repplace the existing connections. The controller units are of "Hybrid" model and ready for connection of additional solar panels.

The "Off-Grid" solution delivers energy even when there for the moment is no wind as they can accumulate the energy in batteries.The inverter technology in the solutions from 1 kW and up delivers 230V or 380V to your socket and there is no more hassle with 12V or other solutions.This system is a position-fixed and silent VAWT system, thus makes it possible to be installed at any places including in some bad locations like on the roof of the house, on the boat, in the snow area and other difficult locations.

"Grid-Tie" model has no batteries for energy accumulation. In this solution you have predefined  consumtion points that are routed to the wind turbine solution. In Finland there is ongoing plans to change the directives so that one can supply the overproduction to the piblic Grid. http://www.kauppalehti.fi/5/i/talous/uutiset/etusivu/uutinen.jsp?oid=2010075351&ext=rss
