Do solar cells degrade with age?
Yes, but it is very slow.
My personal experience (I’ve had PV on my roof for four years) is that it is no more than a loss of 1 or 2% in efficiency each year. For academic purposes, I’ve referenced some thesis research on the topic (below).
All of the manufacturers should give you some specifications on expected degradation.
Finally, the biggest challenge that I have had with my solar installation has been the inverter, not the panels. I am now on my third inverter. Hopefully, the third time is the charm.
