What is a power warranty for solar panels?

A power warranty for solar panels states the expected output of a panel after certain periods of time (eg 5 years, 10 years, 20 years).

If the panels do not perform as promised, you may be able to get them replaced or repaired - but some power warranties do not cover defects.
