How long is the warranty period for rooftop photovoltaic panels
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.
FAQs about How long is the warranty period for rooftop photovoltaic panels
How long is a solar panel warranty?
Solar panel warranties vary depending on the manufacturer, but in the solar industry, a 10-year product warranty and a 25-year performance warranty are typically considered the minimum standard. However, some manufacturers provide a 25-year product warranty and extend the performance warranty to 30 years. How Much Does a Solar Panel Warranty Cost?
What is a performance warranty on a solar panel?
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.
What types of warranties cover solar panels?
There are two basic types of warranties that cover solar panels. A product warranty protects you from defects in a solar panel stemming from material quality or manufacturing errors. This is also referred to as an equipment or materials warranty
How do I get a solar panel warranty?
Generally, the most robust warranties are obtained by hiring installation companies certified by the solar brands they represent. Alternatively, long warranties can also be secured from solar manufacturers that provide their own installation services. What Is Not Covered by a Solar Panel Warranty?
What is a solar product warranty?
Critically, solar product warranties cover manufacturing defects rather than any issues that arise during or after your installation. For a product warranty to remain valid, a certified solar professional may need to handle, install, and maintain your solar panels, inverters, or batteries. 2. Performance warranties
Why do you need a solar panel warranty?
The less solar power your system produces, the more your home may need to draw from the utility company, which eats into your savings. A good solar panel warranty ensures your solar panels maintain a certain level of performance throughout the years, protecting your expected return on investment.
