FREMONT, Calif. (AP) — The bankrupt solar company Solyndra Inc. is auctioning off surplus assets this week as part of its bankruptcy proceedings.Starting Wednesday buyers can purchase the former solar manufacturer's office microwave, artwork that once hung on its walls and an array of heavy equipment and tools owned by the former solar panel maker. The auction ends Thursday at 5 p.m.The auction company Heritage Global Partners is calling the event the "solar auction of the year." Because the company is still up for sale, its facilities and major manufacturing equipment will not be auctioned.Solyndra, which received a $528 million federal loan guarantee and was touted by President Barack Obama as an example of his emphasis on so-called "green jobs," filed for bankruptcy in September and laid off 1,000 workers.
