Solar panel warranty is an important factor when installing a residential rooftop solar system. The main goal of the solar system is to reduce the power bill, so you can save money. When you are choosing cheap panels with less warranty period, you will end up spending more. Solar Panels are most vulnerable to climate change. Warranties protect your solar investment and are an important part of any solar installation.
Solar panel manufacturers are providing two types of warranties, the first one is a product warranty and the second one is a performance warranty. Depending on the company and type of panels, this warranty may change. Before installing the solar system, it is important to make sure you get the best deal for your solar energy system.
Product Warranty
A solar panel’s product warranty covers the integrity of the panel itself and protects you against problems such as manufacturing defects, environmental issues, premature wear, and tear, etc. The warranty period is also important for homeowners to know. While typical product warranties can span 10 to 25 years, the longer the warranty, the better for you.
The product warranty covers manufacturing defects, scratches, strains, rust, spots, junction box loose connection, faulty connectors, cell connector issues, defective back sheet, etc., In Australia, top solar manufacturers are providing 10 to 12 years product warranty. Some manufacturers provide 25 years product warranty for the latest panels that use advanced technology.
Performance Warranty
A solar panel performance warranty is also important as a product warranty. Exposing to the various climate conditions, its performance may go down gradually. The solar system provides an expected output of electricity and that output naturally decreases over time.
Panel manufacturers are providing a linear warranty, typically guaranteeing 90% production at 10 years and 80% at 25 years. If performance dips below that, then the manufacturer will address the issue. Performance warranty may differ from company to company and product to product. Top solar panel manufacturers are providing 25 to 30 years performance warranty.
