Shortly after it opened a massive $700 million facility, it canceled plans for a public stock offering earlier this year and warned it would be in significant trouble if federal loan guarantees did not go through.

The company has said it will make a statement at 9am California time, though it's not clear what that statement will be. An NBC Bay Area photographer on the scene reports security guards are not letting visitors on campus. He says "people are standing around in disbelief." The employees have been given yellow envelopes with instructions on how to get their last checks.

Solyndra was touted by the Obama administration as a prime example of how green technology could deliver jobs. The President visited the facility in May of last year and said "it is just a testament to American ingenuity and dynamism and the fact that we continue to have the best universities in the world, the best technology in the world, and most importantly the best workers in the world. And you guys all represent that. "

The federal government offered $535 million in low cost loan guarantees from the Department of Energy. NBC Bay Area has contacted the White House asking for a statement.

Some Republicans have been very critical of the loans. "I am concerned that the DOE is providing loans and loan guarantees to firms that aren't capable of competing in the global market, even with government subsidies" Florida Congressman Cliff Stearns told the New York Times.
