PCG Clean Energy & Technology Fund (East) LLC is listed as one of the investors in the project that has been given the staggering loan, which even dwarfs that given to failed company Solyndra.

Other investors include one of the major investors in Solyndra, which is run by one of the directors of Solyndra.

Steve Mitchell, who served on the board of directors at the bankrupt energy company, is also managing director of Argonaut Private Equity, which has invested in the latest project.

Since Solyndra has filed for bankruptcy has been asked to testify about the goings on at the firm by two members of the House and ‘asked to provide documents to Congress’.

Republican critics of the President Obama’s solar energy program have voiced their outrage at the new loans while the Solyndra scandal is still being investigated.

They have raised concerns that the Department of Energy is rushing through the approval of loans before stimulus funds expire on Friday.

While the departments insists the projects are being properly vetted, some lawmakers have written to express concern that they vast loans are not being adequately scrutinised.

‘The administration’s flagship project Solyndra is bankrupt and being investigated by the FBI, the promised jobs never materialised, and now the Department of Energy is preparing to rush out nearly $5 billion in loans in the final 48 hours before stimulus funds expire — that’s nearly $105 million every hour that must be finalised until the deadline,’ said Florida representative Cliff Stearns, who is chairman of the investigations subcommittee of the House Committee on Energy and Commerce.
