The US is preparing to hit back at China's glut of cheap solar panels by targeting its allies

• US solar companies accused Chinese firms in Southeast Asia of dumping cheap solar panels on the market.
• A glut of solar panels has cut prices in half in the past year to as low as 10 cents per watt.
• US solar companies want the Biden administration to impose steeper tariffs on imports.

The world is awash in solar panels after Chinese-owned firms flooded the market with cheap exports.

Now, seven US solar companies are fighting back against what they say is a dire threat to America's efforts to build up a manufacturing sector of its own.
