Solar Photovoltaic Panel Warranty

What warranties does a solar system have?

Today, most home solar energy systems include three primary coverages: product warranties, performance guarantees, and installation warranties. 1. Product warranties A solar product warranty covers the physical components of your system, such as the panels, inverters, or batteries.

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 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

Do solar panels have a performance warranty?

A performance warranty, on the other hand, guarantees that your solar panels will produce a certain amount of electricity over their lifespan. Most performance warranties promise that panels will operate at 90% capacity for the first 10 years, then 80% for the remaining 15-20 years.

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.

How long does a solar panel warranty last?

The average warranty coverage from panel manufacturers includes 25 years of coverage for the equipment and manufacturer defects and 25 years of guaranteed maximum efficiency losses. Most manufacturers don’t handle installations as well, so they don’t typically provide labor or roof leak warranties.
