If you’re considering installing solar panels, you’re also basing your decision on a few factors, including price, aesthetics, and inverters. However, one final factor to consider is how long the solar panel warranty is. After all, the expected lifetime of solar panels<\/a> is limited, and we need to ensure that our purchase will last through years of use. Solar panel warranties could be clearer, and it’s difficult to understand the technical jargon. In this article, we’ll explain solar panel warranties in easy-to-understand language.<\/p>\n\n\n

What is a solar panel warranty?<\/strong><\/h2>\n\n\n

A solar panel warranty is a guarantee from the manufacturer that its panels will perform as expected for a certain amount of time. If you have problems with your panels during this period, then you may be able to get them repaired or replaced free of charge by the manufacturer<\/a>.<\/p>\n\n\n\n

Solar panel warranties are an essential part of owning a solar energy system. Manufacturers typically include them in the purchase price of your solar panels, and they can provide peace of mind if something goes wrong with them. The length of time covered by a warranty will vary depending on which company you purchase your system. They typically range between 10 and 25 years long.<\/p>\n\n\n

Types of Solar Panel Warranties<\/strong><\/h2>\n\n\n

Solar panel warranties come in two forms; performance warranties, which cover the efficiency of your system, and product warranties, which cover any defects in materials or quality.<\/p>\n\n\n

Performance warranty<\/h3>\n\n\n

A solar performance warranty guarantees that the solar panels will provide a certain amount of energy over a while. Often, this warranty will ensure that your solar panels generate at least 80% of the electricity stipulated in terms of watts throughout their lifespan. The warranty length depends on several factors, but it can range from 10 to 25 years.<\/p>\n\n\n\n

The power generated by your panels generally decreases as time goes by. A phenomenon known as Light Induced Degradation<\/a> (LID) causes this. This results in a 3% energy output drop in the first year, with succeeding years seeing a maximum of 0.7% loss. Depending on the solar manufacturer, your panels may remain at a 92% power output rate after the 25th year.<\/p>\n\n\n\n

There are two types of performance warranties; linear and step.<\/p>\n\n\n\n
