A quick search shows that the company referenced in that article, Solyndra, made CIGS panels, which, like I said, are relatively rare, in large part because they were a failed startup that went out of business.

The vast majority of panels use crystalline Silicon.

The article also conflates warrantied lifespan with average lifespan. Solar PV cells can last much longer than 20 years.
