What is the lifespan of a PV system?
20 Mar 2013

PV systems are currently considered to have at least a 25-year lifespan. PV panels are covered with a long term performance guarantee (usually 10 years with less than 10% decrease and 20 years with less than 20%) by most manufacturers. Guarantees for electronic components such as inverters can also be extended for several years beyond standard terms.
