They are made here and are Hugh Piggotts design and a very simple, robust and cost effective Wind Turbine.
Every year they need maintenance and re-balancing.
And from the last page of this Chapter 18.
After 15 years of Wind Turbines MY CONCLUSIONS in 2022.
Sad to say, that today wind turbines of this size are just NOT COST EFFECTIVE. If I am asked, “Should I put up a wind turbine to make electricity”, I reply, "The sums no longer add up when PV has become such a very cost-effective solution.”
Okay, Costs for me today. I have just installed 3.3kW of PV, static mounting on one of our roofs and used GTI's, and the system all working for $1800. To make a complete Wind Turbine, Mast, controller etc, at a rated 1kW output is about $1900. So, my new PV installation is heading towards being 3 times better value. And added bonus, ‘there are no moving parts to service’.
Your garage roof has a lot of un PV'd area which should be utilised.
