We bought land in a remote Colorado area and the price to have electricity to the property was about $10,000. So, we are going off-grid. We purchased a 10 foot section of steel pipe and a flange to attach the turbine to the pipe and attached it to our RV batteries which are connected in series.We did not know a blizzard was on the way that day. The wind speed was at least 50 mph sustained with gusts much higher (slammed me against the RV). This thing worked great. It made it through the storm and is still working. I plan to but more. It was not overly noisy until the wind speed kicked up, I am impressed.
