The lifespan of solar panels

The service life of solar panels is determined by the materials of the cells, tempered glass, EVA, TPT, etc. The life of panel can be up to 25 years if manufactured with good quality material, but with the influence of the environment, the material of the solar panel ages over time. Normally the output power will be attenuated by 30% in 20 years, and 70% in 25 years.
