Explain the mechanism by which you believe photovoltaic panels start failing.
Your concern would be valid for a nuclear thermal power station, a Goldberg machine with millions of moving parts. It is not really applicable to semiconductors.
Everything fails given a long enough time span.
For solar PV it is ~30 years.
While the cell may continue to generate power, it may have diminished so greatly as to no longer justify its physical footprint
