We then also need to know how long the panels last. Manufacturers claim 30 years while empirical evidence suggests a mean scrapage age of only 17 years in Germany. Ferroni and Hopkirk use a generous 25 year unit life.

It's not that the panels' output declines to 0, it's that the panels don't tend to last quite as long as claimed.
