Top solar companies, banks and insurers have stopped doing business with at least a half dozen recently built ?U.S. panel factories because of uncertainty over whether their ties to China could disqualify them from clean-energy subsidies.

The emerging effects dovetail with U.S. President Donald Trump¡¯s broader efforts to block Chinese companies from the U.S. market and to slash government support for green energy. The shift, driven by new Trump administration policies, jeopardizes more than a third of U.S. solar capacity in factories initially built by Chinese firms.

The policy could backfire by imperiling growth in U.S. manufacturing jobs and power generation at a time of rising utility bills and soaring electricity demand from data centers serving the artificial intelligence industry, industry experts ?say.
