Abound Solar, a company that won a $400 million Energy Department (DOE) loan guarantee in 2010 to manufacture advanced solar panels, is closing and filing for bankruptcy, according to DOE. Abound’s collapse follows last year’s demise of the solar company Solyndra and is sure to feed Republican attacks on White House green energy programs despite support for Abound’s loan from several GOP lawmakers ahead of its approval. The Colorado-based Abound had drawn $70 million of the loan, according to DOE. Abound will close its doors and file for bankruptcy next week, the department said.
