How long do solar panels last? The lifespan of solar panels is a crucial consideration for those looking to invest in renewable energy. Generally, solar panels are designed to last for decades, with most manufacturers offering warranties ranging from 20 to 25 years. However, research suggests that solar panels can continue to generate electricity well beyond their warranty period, with many panels retaining around 80% of their initial efficiency after 25 years of operation. Factors such as the quality of materials, manufacturing processes, and installation techniques can influence the longevity of solar panels. Regular maintenance and proper care, including periodic cleaning and inspection, can also extend their lifespan.
