In a panel with 20 percent efficiency for instance 20 percent of all the light that hits it will be translated into electricity. From what i understand in the real world the lifespan of a solar panel is about 25 years. However this doesn t mean that they stop producing electricity after 25 years it just means that energy production has declined by what manufacturers consider to be a significant amount.
