6 FAQs about [Photovoltaic panel quality warranty period]
What is a solar panel performance warranty?
A solar panel performance warranty guarantees that a home solar panel installation will meet or exceed a baseline of electric power output over the panels' lifetime and warranty period.
How long do solar panel warranties last?
While the industry standard is 25 years, some manufacturers now offer warranties up to 30 or even 40 years. For example, Silfab offers a 30-year warranty, and Maxeon provides a 40-year power warranty.
How much does a solar panel warranty cost?
In most cases, the cost of a solar panel warranty is $0. Solar manufacturers typically include both the product warranty and performance warranty with the purchase of the panels. A solar system is a long-term investment, with a typical lifespan of 25 to 30 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
What is a solar energy power output warranty?
Solar energy power output warranties help guarantee that your panels won’t rapidly lose efficiency, which would lead to lower and lower energy savings over time. The typical solar array pays for itself in around 11 years and provides energy savings of more than $31,513 over the following 14 years of expected panel life.
What is a solar warranty?
A product warranty is often called a lifespan, equipment, or material warranty. The solar lifespan warranty covers the actual panels against defects, equipment failure, and environmental issues that may cause the panel to stop producing electricity.
