How long do solar panels last?

Solar panels, when properly maintained, can have a lifespan of 25 to 30 years or more. Their longevity depends on various factors such as the quality of materials used, the manufacturing process, and the level of maintenance. Most reputable solar panel manufacturers offer warranties that cover the panels for 25 years, guaranteeing that they will still generate a certain percentage of their original power output during this period. However, it is common for solar panels to continue producing electricity beyond the warranty period with only a slight decrease in efficiency each year. Regular cleaning, inspections, and timely repairs if necessary can significantly extend the lifespan of solar panels, ensuring they continue to generate clean and renewable energy for many years.
