Why 9 out of 10 solar panels fail silently? Ongoing degradation kills efficiency—ours lasts 25+ years, guaranteed.

December 26, 2025

Investing in solar panels is a commitment to over 25 years of clean energy and potential savings, yet it's crucial to understand that solar panels experience gradual degradation in efficiency over time, typically losing about 0.5% to 0.8% of their performance annually. After 10 years, panels still produce 92-95% of their original output, and after 25 years, this drops to 80-85%. Factors influencing degradation include panel quality, climate conditions, and maintenance practices. While manufacturers guarantee at least 80% efficiency after 25 years, many panels last longer when properly cared for. For example, a 5 kW solar system in India with a 0.5% degradation rate will still produce approximately 6,125 kWh/year after 25 years, significantly impacting savings and payback periods. Innovations in solar technology, such as PID-resistant modules and bifacial panels, are helping to slow degradation rates, and future advancements may lead to even longer-lasting panels. To maximize lifespan, solar owners should ensure professional installation, regular cleaning, scheduled maintenance checks, and use monitoring tools to track performance. Ultimately, while solar panels do lose efficiency, the decline is minimal compared to the long-term benefits of clean power and financial savings.
