I have a couple of turbines that won’t spin. My guys have been installing these for years and this has never happened before. It’s not a wormaniship issue.
The rest will continuously spin but the ones circled will stop if its not a strong wind. The turbines have been inspected and I don’t see anything mechanically wrong with them.
Now the client is concerned about our workmanship.
Roof pitch is 10/12
Any advise is appreciated
