Solyndra: a premium solar product undone by a collapse in silicon prices

Solyndra's distinctive cylindrical solar panels avoided expensive polysilicon, which made sense when silicon prices spiked. When polysilicon prices collapsed and cheap conventional panels flooded the market, its cost advantage vanished — just after it had built a large new factory.

What happened

Filed for bankruptcy in September 2011; about 1,100 workers lost their jobs, and it became a major political controversy.

What Solyndra was

Founded in 2005, Solyndra made solar panels from glass tubes coated with thin-film material instead of flat crystalline silicon. The design was easier to install on flat commercial roofs and avoided polysilicon, which was scarce and expensive in the mid-2000s.

In 2009 it received a $535 million loan guarantee from the US Department of Energy and built a new factory in California. Two years later it filed for bankruptcy, and its failure became a long-running debate about government clean-energy lending.

Why it failed

  1. 1

    The advantage depended on a temporary shortage

    Solyndra's economics looked strong while polysilicon was expensive. High prices attracted new supply, polysilicon prices fell steeply from their 2008 peak, and conventional panels became far cheaper to make.

  2. 2

    A wave of low-cost competition

    Manufacturers with enormous scale — many in China, supported by cheap financing — drove panel prices down quickly. Solyndra's more complex product couldn't compete on cost per watt.

  3. 3

    Scaling capacity into a falling market

    It committed to large-scale manufacturing just as the market price of its output was dropping, locking in fixed costs at the worst possible moment.

The product lesson

Know which input your advantage really depends on. If your edge is 'we avoid an expensive component', model what happens when that component gets cheap — because high prices attract new supply. Solyndra's technology wasn't the core problem; its business case was an implicit bet that commodity prices would stay high.
