Shifting the small off grid thread a little, I'm trying to find replacement wind turbines for the Bergey XL.1 in the 1-2 kw range that is quiet and the blades don't blow off. Bergey is suggesting Bornay 1kw. Does anyone have first hand knowledge about this turbine or the manufacturer. I am interested in performance, sourcing etc. After having to sell my Pika T701 to a customer i have tried cheap ($1000) chinese that turned out to be a 300 watt turbine and didn't last a year before the hub casting broke and the blade and turbine landed 200' from the tower in pieces.
