Under product warranty, the manufacturer supports solar panel owners against defects that include damaged panels and manufacturing errors. If your panels crack, delaminate, or
Solar panel degradation is expected, but how it''s covered varies. Most top-tier manufacturers now offer linear performance warranties, ensuring energy output declines at a
Learn about solar panel warranties, inverter warranties, and all the warranty coverage information to know when installing a home solar system in this guide.
Solar panel manufacturers guarantee their products are free from material and workmanship flaws. Their warranty typically lasts for 10 to 25 years, offering extended coverage.
All PV panels degrade and lose efficiency over time, and a solar panel performance warranty tells you the maximum degradation you can expect over the warranty period.
Solar panels naturally degrade slightly each year, but performance warranties typically guarantee that panels will still produce at least 80-90% of their original output after 25 years. For
While not provided by the manufacturer, an installer warranty covers the workmanship and installation of your solar system. This can include issues like roof leaks or electrical problems
While manufacturer warranties primarily cover issues related to the solar panels themselves, such as material defects, workmanship defects, and loss of power output, the solar
Most solar panel manufacturers will guarantee at least 80% of the
Most solar panel manufacturers will guarantee at least 80% of the original output by the end of the warranty term, or about 0.7% degradation each year. A few things to look out for when
Learn the differences between solar panel warranties: performance, product, and workmanship. Understand what each one covers and what to ask your installer.
