    Solar Panels and Accessories are unlikely to fail. But when you invest thousands of dollars in installing a solar setup, you want to know how the manufacturer will protect your purchase. Therefore, it's a good idea to research and understand solar panels and accessories warranties in advance so that you can have peace of mind regarding coverage and protection.


    How long do solar panels and accessories last?


    Usually, the first question people ask during solar research is: how long do solar panels and accessories last? How long will it take to recoup the investment? To answer this question, the lifespan of solar panels and accessories is at least 25 years. This is also the length of the average warranty period — the standard in the solar industry. Essentially, solar panel manufacturers guarantee that your panels can generate power for over 25 years. Over time, your panels will undergo slight degradation — as the panels age, the output naturally declines. Most high-quality solar panels lose 0.3% to 1% of their rated wattage annually. This is known as the degradation rate, and the warranty structure of solar panels and accessories takes this into account.

    Understanding what a solar panel and accessories warranty covers


    Solar panel and accessories warranties come in two types: performance warranty and product warranty. The performance warranty essentially guarantees that your panels will continue to function properly during the warranty period, while the product warranty covers any issues related to manufacturing defects.


    When shopping around for solar panels and accessories, be sure to read and review the warranty terms of each product.

    Solar Panel Performance Guarantee


    Over time, all solar panels and accessories degrade. This means that every year you can expect a slight drop in the power output of the system. However, the degradation rate of solar panels and accessories depends on the quality of the solar cells within the solar panels. You can evaluate this through the performance guarantee of the solar panels, which is essentially a manufacturer's performance assurance.


    Solar panel performance warranty usually lasts for 25 years. Most performance guarantees ensure that solar panels and accessories can still produce 80% to 90% of their rated power output by the end of the 25-year warranty period. Solar panels with better performance guarantees usually cost more but may last longer and produce more solar power over the years.


    Solar Panel Product Warranty


    The product warranty is the solar panels and accessories craftsmanship guarantee, covering manufacturing defects, wiring issues, or premature wear and tear. The product warranty of many solar manufacturers is around 10 to 15 years. Some other solar panel manufacturers offer up to 25 years product warranty.
