How long will solar panels last?

Most solar panels come with something around a 25 year warranty, so they are guaranteed to last 25 years. When you re doing an economic analysis to evaluate whether or not it is worth it to put in a solar power system, you usually use a 30 year life span, but panels are regularly known to last at least 40 years.
