A solar panel’s performance warranty will typically guarantee 90% production for the next 10 years and 80% at 25 years, meaning whatever your solar panels are generating today in standard conditions they can produce at least 80 % of it at the end of 25 years.
An equipment warranty is typically for 10-12 years and it protects your solar panels from any manufacturing defects. Meaning in 10-12 years if there is any wear your solar panel will be repaired or replaced
