Of the many promises Donald Trump made during the campaign, few resonated more than getting tough on trade and bringing manufacturing jobs back home. That promise gave one struggling solar company an idea: ask the President to tamp down on the glut of cheap solar panels coming from overseas.

And the solar industry is freaking out. If approved, it could cost tens of thousands of jobs and bring installations to a halt.
