it works well, on paper and for metals. PV panels are glass sandwiches so moisture ingress and damage is inherently slow, something accelerated ageing can't capture well. From first hand experience, the warranties on PV panels aren't all they are made out to be. For one, manufacturing runs of many panel models last months. after, while the warranty will be honoured, you won't be receiving identical panels either electrically or cosmetically. Worse still is when the equivalent offered has different dimensions. The warranty itself is good but doesn't account for practical considerations especially when you are working with a component that's part of a larger whole.
