Ah, fair enough. These articles tend to be generous with interpretations of their poorly cited sources. Still, without knowing where the early PV systems are in the US, it's a difficult claim to back up. There is also survivorship bias and the fact that quality control on small batches of any product is usually better than on mass market stuff. After the section you referred to, the article goes on to claim that poor regulatory oversight is responsible for the short lifespan of Australian PV systems... again, a questionable claim.
