I keep hearing of these magical lifetimes. I've had 2 different brands and multiple panels are taken out of the circuit because they degraded too much.
My neighbour has the same panels but never looks at the output. I told him to check them and he was shocked. How many others are there they simply don't check the output and keep spouting that panels have multi decade lifetimes.
