What’s the energy payback time for making a solar panel?

By Ben Delman on October 18, 2019

Energy payback is the amount of time it takes a solar panel to produce more energy than was used to produce it. This time varies by panel and by technology. Even as far back as 2004 when manufacturing processes were less efficient, it took less than four years for a standard solar panel to generate more energy than was used in making it. And remember, solar panels can generate electricity for 25 years or longer!
