Quality solar panels come with three different types of warranties. Let's look at what those are.
When most people think of warranties, they think of a product warranty. A product warranty is what covers the item you have purchased against manufacturer defects. This warranty is typically offered on consumer items like household appliances. LG is able to offer a 25 year warranty against defects, breakage or any other product issues, in the rare case that one would arise. To give you an example of how rare it is that an LG panel would experience an issue, of the roughly 800,000 panels sold in Australia within the past eight years (at the time of writing), less than 20 had warranty claims due to manufacturing faults. That's a failure rate of approximately 0.00025 percent. No wonder they are guaranteed for so long!
When the sun shines on solar panels the change that occurs to the panel is called scorch. Scorch causes all panels to lose efficiency over time. While scorch affects all panels, some panels resist it better than others. LG's performance warranty guarantees your panel's performance over a 25 year period. For example, the LG NeON® R is guaranteed to work to 88.4 percent of its day one capacity after a quarter of a century of use. Standard panels won't guarantee this type of production. It is important to know what the performance guarantee is for the panel you buy.
Here are some of the questions you should ask your solar professional about your warranty prior to making a decision.
ο How long is my warranty? Is there a difference between the length of the product, labor and performance coverage?
ο Who do I contact in the event of a claim?
ο What is covered under my warranty? What is not?
ο Are incidentals covered?
ο Is the warranty transferable?
ο Do I have to register my warranty before I can make a claim?
Be sure to find out all of the information you can about your manufacturer's warranties before making a final decision. The savings of a cheap panel may seem intriguing in the moment, but a high-quality panel with a manufacturer that stands behind it will provide you with security in your investment long-term.
