Solyndra was a manufacturer of cylindrical panels of copper indium gallium selenide (CIGS) thin film solar cells. It was based in Fremont, California. In 2009, the Obama administration co-signed $535 million in loans to Solyndra.{{cite news |author1=Broder, John M |title=Energy Department Issues First Renewable-Energy Loan Guarantee |url=https://www.proquest.com/docview/1917598032 |access-date=18 February 2022 |work=The New York Times |date=20 March 2009 |id={{ProQuest|1917598032}} |language=en |quote=The $535 million loan guarantee will go to Solyndra Inc. ...

History
Chris Gronet founded what would become Solyndra in May 2005.{{cite web|url=https://medium.com/@kennedymaize/sunburned-18e9d17d238|title=Sunburned: The Solyndra Story| first= Kennedy |last= Maize |publisher= Medium.com |date=2014-06-02|access-date=2020-06-08|archive-date=November 16, 2020|archive-url= https://web.archive.org/web/20201116162755/https://medium.com/@kennedymaize/sunburned-18e9d17d238|url-status=live}} In 2006, Solyndra began deploying demonstration systems globally. The company reported deploying 14 systems that were each instrumented with sensitive radiation, wind speed, temperature, and humidity measurement devices to aid in the development of energy yield forecasting software tools. According to the company, over 1,000 systems were installed worldwide, representing 100 megawatts of power.{{cite web| url= http://www.solyndra.com/technology-products|title=Technology/Performance, Proven Performance|work=Solyndra.com|publisher=Solyndra LLC|access-date=20 April 2012|url-status= dead |archive-url=https://web.archive.org/web/20120430075507/http://www.solyndra.com/technology-products/|archive-date=30 April 2012}}

Brian Harrison, a veteran of Intel Corporation, briefly led Solyndra. He took the reins on July 27, 2010, a little more than a year before the company went bankrupt. Harrison replaced founder Gronet, who had served as CEO since the company's inception in 2005.{{cite web|url=http://www.solyndra.com/2010/07/brian-harrison-joins-solyndra-as-president-and-ceo/|title=Brian Harrison Joins Solyndra as President and CEO|date=July 27, 2010|work=Solyndra.com|publisher=Solyndra LLC|access-date=June 14, 2012|url-status=dead|archive-url=https://web.archive.org/web/20120619043330/http://www.solyndra.com/2010/07/brian-harrison-joins-solyndra-as-president-and-ceo/|archive-date=June 19, 2012}}

Following the company's 2011 bankruptcy, the government had expected to recoup $27 million under the Solyndra restructuring plan, or up to 100% of loaned funds from a $1.5 billion lawsuit filed against Chinese polysilicon solar-panel makers for alleged price fixing.{{cite news |url=https://www.bloomberg.com/news/2012-10-17/solyndra-lenders-ahead-of-government-won-t-recover-fully.html |title=Solyndra Lenders Ahead of Government Won't Recover Fully |first=Michael |last=Bathon |date=October 17, 2012 |work=Bloomberg Business |access-date=November 14, 2014 }} The outcomes of the lawsuits were that, in November 2015, Yingli Green Energy Holding Co Ltd. settled a claim filed by Solyndra for $7.5 million, and in April 2016 Trina Solar Ltd. settled a claim filed by Solyndra for $45 million.

The company manufactured its products in its second fabrication plant, 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. Solyndra had expanded production in 2008. In March, 2009, Solyndra had estimated that:{{cite web|url=http://www.solyndra.com/2009/03/us-department/|title=Solyndra Offered $535 Million Loan Guarantee by the U.S. Department of Energy|date=March 9, 2009|work=News and Information, 2009|publisher=Solyndra LLC|access-date=June 13, 2012|url-status=dead|archive-url=https://web.archive.org/web/20120619041358/http://www.solyndra.com/2009/03/us-department/|archive-date=June 19, 2012}}
- The construction of the new 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 be then duplicated in multiple other manufacturing facilities.
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.
Solyndra announced on November 3, 2010, that it would lay off around 40 employees and not renew contracts for about 150 temporary workers as a result of a consolidation of its production facilities. The company said 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.{{cite news|title=Solar-Panel Maker to Close a Factory and Delay Expansion|first=Todd|last=Woody|newspaper=The New York Times|date=November 3, 2010|url=https://www.nytimes.com/2010/11/03/business/energy-environment/03solar.html|access-date=November 3, 2010|archive-date=November 16, 2020|archive-url=https://web.archive.org/web/20201116162741/https://www.nytimes.com/2010/11/03/business/energy-environment/03solar.html|url-status=live}}

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, 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.{{cite web|title=New Shape of Solar|url=http://www.solyndra.com/technology-products/cylindrical-module/|work=Solyndra.com | publisher= Solyndra, LLC |access-date= 13 June 2012|year=2008|url-status=dead|archive-url=https://web.archive.org/web/20101017025707/http://www.solyndra.com/technology-products/cylindrical-module |archive-date=17 October 2010}}
The company's panels were claimed to be unlike any other product ever tried in the industry: they were made of racks of cylindrical tubes (also called tubular solar panels), not traditional flat panels. Solyndra rolled its CIGS thin films into a cylindrical shape and placed 40 of them in each {{convert|1|by|2|m|adj=on}} panel. Solyndra designers thought the cylindrical solar panels absorbed energy from any direction (direct, indirect, and reflected light).{{cite web| title= Cylindrical Solar Cells Give a Whole New Meaning to Sunroof|url=http://www.scientificamerican.com/article.cfm?id=cylindrical-solar-cells-give-new-meaning-to-sunroof |work= Scientific American |access-date=13 June 2012| first= David |last= Biello|date=7 October 2008|archive-date=November 16, 2020|archive-url= https://web.archive.org/web/20201116162725/https://www.scientificamerican.com/article/cylindrical-solar-cells-give-new-meaning-to-sunroof/|url-status=live}}
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 added 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 filled with a silicone oil,{{cite web| title=Solyndra Photovoltaic 4 Watt CIGS Cylindrical Solar Tube |website= halted.com | publisher= |url= http://www.halted.com/commerce/catalog/product.jsp?product_id=27718|access-date=March 29, 2014 |archive-date= May 15, 2016|archive-url=http://arquivo.pt/wayback/20160515090321/http://www.halted.com/commerce/catalog/product.jsp?product_id=27718|url-status=live}} then sealed with glass and metal to exclude moisture, which erodes CIGS's performance. The hermetic sealing technology is commonly used in fluorescent lamps.{{cite news |url=http://www.greentechmedia.com/articles/solyndra-rolls-out-tube-shaped-thin-film-1542.html |first=Ucilia |last=Wang |date=7 October 2008 |title=Solyndra Rolls Out Tube-Shaped Thin Film |publisher=Greentech Media |access-date=October 20, 2008 |archive-date=November 16, 2020 |archive-url= https://web.archive.org/web/20201116162738/https://www.greentechmedia.com/articles/read/solyndra-rolls-out-tube-shaped-thin-film-1542 |url-status=live }}
When combined with a white roof,{{efn|the fastest growing segment of the commercial roof industry, with over {{cvt|36|sqmi|km2}} 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. It was thought that on a white roof, the panels can capture up to 20% more light than a black roof.{{cite web|title= DDC, Cool and Green Roofing Manual.pdf|url=http://www.nyc.gov/html/ddc/downloads/pdf/cool_green_roof_man.pdf |website= nyc.gov |publisher= New York City Department of Design and Construction|access-date=13 June 2012|page=14|date=June 2005|archive-date=November 16, 2020|archive-url= https://web.archive.org/web/20201116162739/http://www.nyc.gov/html/ddc/downloads/pdf/cool_green_roof_man.pdf|url-status=live}}{{efn|It is difficult to cite a specific reference for this because the exact gain depends on the latitude of the installation (in other words, sun angle). Solyndra's on-line energy modeling tool allowed designers to specify the roof albedo, and energy output varied as a function of albedo. Twenty percent is cited as typical figure and was validated by careful testing and modeling by the Fraunhofer Society, among others. However, this report is not available on-line.}}
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.{{cite web |url=http://www.ecogeek.org/content/view/2187/83/ |title=Tubular Solar Panels Slash Costs, Boost Efficiency |work=EcoGeek |date= 10 July 2008 |access-date=2 September 2011 |first=Hank |last=Green |author-link=Hank Green |url-status=dead |archive-url= https://web.archive.org/web/20110910201016/http://www.ecogeek.org/content/view/2187/83/ |archive-date=10 September 2011 }} 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. Solyndra claimed that wind and snow loads are negligible and that its panels are lighter in weight per area.
The company claimed the cells themselves convert 12 to 14 percent of sunlight into electricity, an efficiency better than competing CIGS thin-film technologies. However, these efficiencies are for the cells laid flat.{{cite web|url=http://www.greentechmedia.com/articles/read/solyndra-works-on-1m-sq.-ft.-project-in-socal/|title=Solyndra Works on 1M Sq. Ft.

The Solyndra 100/200 spec sheet doesn't mention the cells or the panel efficiencies directly. However, calculating from the data provided shows the high-end 210 panel has a field efficiency of about 8.5%.{{cite web|url=https://na6.salesforce.com/sfc/p/80000000Jxojk0hWZ3pLBkRRGwHHx9AXV5lFbSQ=|title=Solyndra 200 Spec sheet|work=Solyndra.com|publisher=Solyndra LLC |year= 2008|access-date=March 9, 2011|archive-date=November 16, 2020|archive-url= https://web.archive.org/web/20201116162728/https://na101.salesforce.com/sfc/p/80000000Jxojk0hWZ3pLBkRRGwHHx9AXV5lFbSQ=|url-status=live}}
