A performance warranty guarantees a maximum level of degradation – typically between .25% and .75% – per year so that in 25 years the panel will still have 80-90% of the power output it did in its first year. Performance warranties are important for sizing solar systems to maintain 100% offset for 25 years.
Most solar panel power warranties nowadays offer linear degradation, meaning a 0.7% output loss per year. However, some manufacturers like SunPower offer a much higher output guarantee after 25 years. In the past, power warranties were stepped, guaranteeing 90% output after 10 years and 80% output after 25 years.
