Although the life of solar panels varies depending on the manufacturer, quality and use environment, in general, the service life of solar panels can reach more than 20 years.

The durability of solar panels depends largely on their material and design. The crystalline silicon solar panels commonly found on the market today have a long life. They are typically made of durable materials and designed to work stably in a variety of climatic conditions. In addition, the service life of solar panels is also affected by normal use and maintenance. Regular cleaning and inspection of solar panels can extend their life and ensure their proper operation.

Although the performance of solar panels will gradually decline over time, their rate of decay is usually slow. Most manufacturers typically offer a 25-year performance guarantee that the solar panel’s power output does not fall below a specific percentage of its rated value during that period. This means that even after a certain degree of decay, solar panels can still provide reliable clean energy for a home or business.

In summary, the life of solar panels can usually reach more than 20 years, and has a durable design and materials. Regular maintenance and attention to conditions of use will help ensure the long-term performance and reliability of solar panels.
