Shares of U.S. solar energy companies collapsed in a trading session Friday after Senator Joe Manchin told Democratic leaders that he would not support an economic climate protection package. It was reported by Bloomberg.

Shares of Sunrun (-8.55%, to $23.01), SunPower (-4.47%; $15.82), SolarEdge Technologies (-2.26%, to $262.95), and First Solar $64.96 (-8.57%, to $64.96) are down rapidly.

The Senate is discussing the possibility of directing several hundred billion dollars in climate change funding. Among the proposed measures are tax credits for renewable energy and electric cars.
