What Are the Warranties on Solar Panels After 10 Years?

When it comes to solar panels, there are several warranties that come into play. A solar panel's performance guarantee typically guarantees 90% production at 10 years and 80% at 25 years. Additionally, an equipment warranty normally guarantees 10 to 12 years without failure. Furthermore, solar panels also come with a labor warranty offered by the contractor who installs the product.

This is usually for an average of 10 years. It is essential to understand that different types of home solar panel systems offer different solar panel warranties. Therefore, it is important to keep four key considerations in mind when making a decision about products and services. To get a more complete list, be sure to ask your solar installer's sales representative for information about specific causes and conditions that could void your product warranty or the performance of your solar panels. A product's warranty protects it from faulty equipment, while a performance warranty ensures that solar panels maintain a certain level of performance throughout their lifespan, typically 25 years.

Most solar panel manufacturers back their products with a 25 to 30 year linear performance warranty. If you are planning on selling your home, contact your solar installer and the solar panel manufacturer to let them know and begin the warranty transfer process. Additionally, if you add solar storage to your system, most solar batteries come with a separate 5 to 10 year warranty. The lifetime warranty for solar energy covers real panels against defects, equipment breakdowns, and environmental problems that could cause the panel to stop producing electricity. If your home insurance does not cover your solar panels, it might be worth looking for insurance specifically for solar panels to protect your investment. Solar panels are designed to withstand extreme weather conditions, but problems can still arise, so a warranty provides essential financial protection to consumers of solar equipment.

Warranties provide financial security to consumers, as they can protect their solar panel system against defects, performance issues, or other problems. Solar panel production will naturally degrade over their lifespan, although normally no more than 10 to 20% in 25 years, and usually between 0.5% and 1% for each year of service. A solar panel's performance guarantee ensures that a home solar panel installation will reach or exceed an electrical energy production baseline over the life and warranty period of the panels. Together, they protect you from panel defects and ensure that your panels can perform at a certain level throughout their lifespan. Finally, check with your agent about the warranty, insurance, and solar panel coverage available in your homeowner's insurance policy.
