A photovoltaic solar panel has, on average, a lifespan of between 25 and 30 years, maintaining most of its production capacity. Most manufacturers guarantee the performance of the modules for 20 to 25 years, and even after that period, it is common for them to continue producing about 80% of the initial power. Other components, such as the inverter, typically have a shorter lifespan and may need replacement after 10 to 15 years.
