A better product, should have a better warranty, and that is why SunPower Performance panels have a comprehensive 30-year warranty that covers Power, Product and Service (subject to terms and conditions that can be found in our warranty documentation).
Our latest generation, SunPower Performance 7 solar panels are manufactured for long-term durability—covering defects related to workmanship and materials for a full 30 years. The 30-year warranty for SunPower Performance 7 solar panels requires registration, otherwise our 25-year warranty applies, and this warranty is not available for earlier generation SunPower Performance solar panels, where a 25-year warranty applies.
Some manufacturers of standard panels go as low as 12 years on their product defect warranty, which could leave your organisation open to risk if anything should go wrong with the panel. It is best to carefully review warranty documentation before investing in solar panels for your organisation.
