Solyndra was a manufacturer of cylindrical panels of CIGS thin-film solar cells based in Fremont, California. The company suspended all of its operations as of August 2011 leaving behind the United States government as its largest creditor.[1]
In May 2010, the company was personally promoted by President Obama in his visit as a model for government investment in green technology,[2] and was also visited by former California governor, Arnold Schwarzenegger.[3] A $535 million loan guarantee was applied for under the Bush administration but the loan was denied.[4] The $535 million loan guarantee was later granted by the Obama administration. Private investors also invested more than $1 billion into the company.[2]
Due to overseas price pressure coming from China in the period of constructing the new plant, the Fab 2, the company had shut-down its original plant, Fab 1, and simultaneously reduced its staff to approximately 1,100 employees.[5] In early September 2011, the company ceased all business activity, filed for Chapter 11 bankruptcy, and laid-off all employees.[3] The company is also being sued by employees who were abruptly laid-off.[2]
On September 8th, 2011, Federal Bureau of Investigation Agents executed multiple search warrants at the company's headquarters in Fremont as part of an investigation by the Department of Energy's Office of the Inspector General.[2]
Technology
Solyndra designed, manufactured and sold solar photovoltaic (PV) systems composed of panels and mounting hardware for large, low-slope commercial rooftops. The panels perform optimally when mounted horizontally and packed closely together, thereby, the company claimed, covering significantly more of the typically available roof area and producing more electricity per rooftop on an annual basis than a conventional panel installation.[6]
The solar panels developed by the company were claimed to be unlike any other product ever tried in the industry. The panels were made of racks of cylindrical tubes (also called tubular solar panels), as opposed to traditional flat panels. Solyndra rolled its copper-indium-gallium-diselenide (CIGS) thin films into a cylindrical shape and places 40 of them in each 1-meter-by-2-meter panel. The cylindrical solar panels (think of fluorescent tube lights—except in reverse) can absorb energy from every direction (direct, indirect kijhkjjiojoiand reflected light).[citation needed]
Each Solyndra cylinder, one inch in diameter, is made up of two tubes. The company used equipment it had developed to deposit CIGS on the outside of the inner tube, which includes up to 200 CIGS cells. On top of the CIGS material, it adds an "optical coupling agent", which concentrates the sunlight that shines through the outer tube. After inserting the inner tube into the outer tube, each cylinder is sealed with glass and metal to keep out moisture, which erodes CIGS's performance. The hermetic sealing technology is commonly used in fluorescent bulbs.[7]
When combined with a white roof (the fastest growing segment of the commercial roof industry with over 1 billion square feet installed in 2008 and required for any new commercial construction in California), the company claimed that systems that employ the panels on a given rooftop could produce significantly more electricity in a given year. With a white roof, the panels can capture up to 20% more light than with a black roof.[citation needed]
The other advantage claimed by the company was that the panels did not have to move to track the Sun. The panels are always presenting some of their face directly perpendicular to the Sun.[8] The daily production of flat solar panels has an output curve that has a clear peak while Solyndra claimed their system produced more power throughout the day.
The Solyndra panels allow wind to blow through them. According to the company, these factors enable the installation of PV on a broader range of rooftops without anchoring or ballast, which are inherently problematic.[6] Solyndra claimed that wind and snow loads are negligible and that its panels are lighter in weight per area.[citation needed]
The company claimed the cells themselves convert 12 to 14 percent of sunlight into electricity, an efficiency better than competing CIGS thin-film technologies.[7] However, these efficiencies are for the cells laid flat.[9] The company did not post any numbers when the cells are rolled up. The Solyndra 100/200 spec sheet doesn't mention the cells nor the panel efficiencies directly. However, calculating from the data provided shows the high-end 210 panel has a field efficiency of about 8.5%.[10]
In 2006, Solyndra began deploying demonstration systems around the world. The company stated the total count was 14 systems and that these systems were each instrumented with highly sensitive radiation, wind speed, temperate and humidity measurement devices to aid in the development of energy yield forecasting software tools, claiming there were more than 1000 Solyndra systems installed around the world and that they shipped its 100th megawatt of panels in March 2011.[citation needed]
Management and Investors
 | This section needs additional citations for verification. (September 2011) |
Solyndra was led by Brian Harrison, a veteran of Intel Corporation, from July 27, 2010, when Solyndra announced that Brian Harrison had replaced founder Chris Gronet as CEO of the company.
Major investors included George Kaiser Family Foundation, U.S. Venture Partners, CMEA Ventures, Redpoint Ventures, Virgin Green Fund, Madrone Capital Partners, RockPort Capital Partners, Argonaut Private Equity, Masdar and Artis Capital Management.
In 2009, the company posted $100 million dollars in revenue. It was estimated that its production and sales growth could lead to a market cap between $1.76 - 2 billion dollars.[11] 2010 revenues were approximately $140 million.
Other executives include Bill Stover, CFO, Karen Alter, SVP of Marketing, Corby Whitaker, VP, Sales United States, John Gaffney, Corporate Counsel and Ben Bierman, EVP Operations and Engineering.[citation needed]
Loan guarantee
The USDOE, on March 20, 2009, offered a $535 million loan guarantee to Solyndra, Inc. to support the construction of a commercial-scale manufacturing plant for its proprietary solar photovoltaic panels.[12]
Production
The company manufactured its products in its second fab, Fab 2, a new $733 million state-of-the-art robotic facility in Fremont, California which opened in September 2010. Fab 2 was built with the support of a $535 million federal loan guarantee along with at least $198 million from private investors. According to an initial public offering by the company, the combined annual production capacity of the plants was projected to be 610 megawatts by 2013. After expanding production in 2008,[7] the company announced on November 3, 2010 that it was mothballing its older plant, Fab 1, and postponing expansion of recently opened Fab 2, giving it an annual production capacity of about 300 megawatts. Market conditions were cited, with conventional solar modules manufactured in China by low-cost producers such as Suntech and Yingli offering stiff competition. [13]
On 20 March 2009 Solyndra estimated that:
- The construction of this complex would employ approximately 3,000 people.
- The operation of the facility would create over 1,000 jobs in the United States.
- The installation of these panels would create hundreds of additional jobs in the United States.
- The commercialization of this technology was expected to then be duplicated in multiple other manufacturing facilities[14]
On 3 November 2010 Solyndra said it would lay off around 40 employees and not renew contracts for about 150 temporary workers as a result of the consolidation.[13]
Shutdown and investigation
In June 2011, Time reporter Michael Grunwald claimed that "reports of Solyndra’s death have been greatly exaggerated,"[15] a play on Mark Twain's quote, "Reports of my death have been greatly exaggerated."
On 31 August 2011 Solyndra announced it was filing for Chapter 11 bankruptcy protection, laying off 1100 employees, and shutting down all operations and manufacturing, while providing no severance for the fired employees, or even providing back due vacation day credit.[16]
On 8 September 2011, Solyndra was raided by the FBI investigating the company.[17]
