The estimated lifetime of a PV module is 30 years. Furthermore, the modules' performance is very high providing over 80% of the initial power after 25 years which makes photovoltaic a very reliable technology in the long term.

Most manufacturers in general propose performance guarantees on the modules after 20 years of 80% of the initial output power. On the electronic components and accessories (inverters), the guarantee usually does not exceed 10 years.

But this doesn't mean that PV systems don't produce energy after 20/25 years. Most PV systems installed more than 25 years ago, still produce energy today!
