How long do solar panels and inverters last?

Q: What is the life span of the PV array panels and inverter?

A: The panels are warrantied for 25 years to produce at least about 90% of their initial power production. This varies a bit by manufacturer. They will probably last for many years beyond that. My inverter is warrantied for 15 years but new ones today come with a 25 year warranty.
