The lifespan of solar panels is determined by cell materials, tempered glass, EVA, TPT, etc. Generally, the lifespan of panels made by manufacturers who use better materials can reach 25 years, but due to the influence of the environment, solar panel materials will age over time. Under normal circumstances, the power will decrease by 30% after 20 years of use, and the power will decrease by 70% after 25 years of use.
