A standard solar panel’s performance warranty typically assures 90% production for the initial 10 years, and a minimum of 80% over a 25-year period. This means that your panels should continue generating at least 80% of their current output under standard conditions after 25 years.

Meanwhile, the equipment warranty typically spans 10 to 12 years and safeguards your solar panels against manufacturing defects. This coverage ensures that if your panels experience any wear within this period, they will be either repaired or replaced.
