Solar panels generally come with two warranties: The product warranty covers the equipment and typically guarantees at least 10-12 years without fail, and the power or performance warranty often guarantees at least 90% production at 10 years and 80% at 25 years. Even after reviewing extensive documentation, deciphering the disparities between warranties offered by different manufacturers can seem like comparing apples to oranges. . A power production guarantee is a promise from the solar installer that your system will produce a certain amount of energy over a certain period of time. Here, the system will be replaced altogether free. . They protect you from defects, set expectations for long-term performance, and can help with resale value.
