Quick Answer
Solar trackers come with a warranty that typically ranges from 10 to 25 years, depending on the manufacturer and the specific model. This warranty covers defects in materials and workmanship. Most manufacturers also offer a performance guarantee, with some offering a minimum power output threshold.
Warranty Periods for Major Manufacturers
Major solar tracker manufacturers, such as Array Technologies, NEXTracker, and SunPower, offer warranty periods ranging from 10 to 25 years. For example, Array Technologies offers a 25-year warranty on its DuraTrack products, while NEXTracker offers a 25-year warranty on its NX Horizon product line. SunPower offers a 25-year warranty on its X-Series solar panels and trackers. It’s essential to review the warranty terms and conditions for any specific product before making a purchase.
Performance Guarantees and Power Output Thresholds
Some solar tracker manufacturers offer performance guarantees with a minimum power output threshold. For example, SunPower guarantees that its X-Series solar panels will produce at least 98.5% of their rated power output over the first 25 years of operation. This guarantee is based on a combination of lab testing and field data. Array Technologies also offers a performance guarantee, with a minimum power output threshold of 90% of the rated power output over the first 25 years of operation. By understanding the performance guarantees and power output thresholds offered by different manufacturers, you can make informed decisions when selecting a solar tracker system.
