Solyndra's tech didn't use polysilicone. Which was great when polysilicone prices were high. When the prices went down, the vast majority of panels that used polysilicone got much cheaper and Solyndra couldn't compete. Solyndra's circular tube technology also was problematic because it was designed to work with reflected light from the rooftop and in real world conditions when the roof got dirty you lost a lot of reflected light. So really, it doesn't.
