Don’t solar panels have a life span of like 20 years?
4 comments

Typically they’re warranted to keep supplying something like 80% at the 20 year mark. They’ll actually keep producing a lot longer than that.
They can however fail like any piece of electronics (source: I owned a panel that failed due to cell foil contact separation).
So I assume the panel was replaced under warranty? Was everything pretty much covered, or maybe you had to pay for some installer labor?
I did not know that. Thanks!
The panels I will be installing guarantee 90% output after 25 years.
Europe's oldest grid-connected PV system is 35 years old, and still running. Inverters had to be replaced 5 times though.

The life span of the inverter also needs to be considered
