The report is clearly aimed at addressing worries about the rapid rise of Chinese solar panel manufacturers, who now represent 58 percent of the world’s solar panel manufacturing capacity.

American solar panel makers have been struggling, including Evergreen Solar, which filed for bankruptcy this month and had already moved early this year to shut down most of its production in the United States.

It takes up to two years for a conventional blue solar panel to produce as much electricity as it took to manufacture the device, prompting critics to suggest that solar panels in some ways resemble batteries as well as power generation technologies.
