For PV modules there are two types of warranties:A product warranty, which covers defects on the solar panels. For that, the industry standard is 5-10 years, with selected manufactures offering up to 20 years.A power output warranty, which covers cases where the power output falls below the guaranteed levels. For that, industry standard is 20-25 years, with selected glass-glass module manufacturers even providing 30 years. [pdf]
[FAQS about Photovoltaic inverter warranty terms]
Standard warranties for lithium-ion batteries covering both performance and defects are two years, but extended warranties can be purchased. A warranty beyond 10 years does not make sense because so much of the battery would need to be replaced after year 10. Insurance can also be purchased. [pdf]
