Top solar companies, banks and insurers have stopped doing business with at least a half dozen recently built US panel factories because of uncertainty over whether their ties to China could disqualify them from clean-energy subsidies, according to industry executives and documents reviewed by Reuters.

Details of how the policy uncertainty is driving installers and insurers away from US solar factories with China ties have not been previously reported.

David Attenborough said he had been "completely overwhelmed" by birthday greetings as he turned 100 in a worldwide outpouring of affection for the British wildlife broadcaster after decades of trailblazing work.
