Does the manufacturing process for solar panels have a large carbon footprint?



  1. 0 Votes

    Yes. One estimate says that a solar panel requires about 600 kg of carbon dioxide to produce. This is because many of the materials that go into the manufacturing – copper, glass, aluminum, and others – have to be mined and require energy to be shaped correctly. Another estimate says that it takes about 4 years for the carbon footprint of the solar panel to be negated by the clean energy it produces. Solar manufacturers are working on decreasing this time.
