I mean, solar panels degrade with time. I've heard "30 years" bandied about, but I've also heard that a lot of Chinese-manufactured solar panels rated for 30 years only last 5-10 years (that may have been specific to Australia, I don't recall).

Chinese-made monocrystalline silicon panels are expected to have extremely long lifetimes (25+ years with no degradation) relative to thin film types (Cd-Te, etc.) However, another main issue is quality encapsulation of the panels; if done shoddily this greatly shortens the lifetime of the panels. Practically, look for manufacturers who have the longest guarantees. https://solaranalytica.com/solar-panel-encapsulation/ https://solaranalytica.com/solar-panel-encapsulation/
