how are solar panels made coal

Best answer


The short answer isno. While some solar panel frames, backsheets and junction boxes are made with coal-reliant polyvinyl chloride (PVC), the panels themselves aren鈥檛 made from coal. That being said, the silicon used to make PV cells requires a lot of energy to be manufactured, which is more often than not coal-powered.

  • How are solar panels made?

  • The first step in making a solar panel is to mine and purify silicon. Purification is usually done with an electric furnace. Thankfully, silicon is a highly abundant resource. In fact, it鈥檚 the second most abundant element (right behind oxygen) on the planet.

  • Where does the silicon in solar panels come from?

  • Silicon can be mined from quartzite, mica, and talc, but sand is its most abundant ore source. The silicon in solar panels is manufactured through a reduction process in which the silica is heated with a carbon material and the oxygen is removed, leaving behind purer, metallurgical-grade silicon.

  • Does solar power use more land than coal power?

  • Utility-scale solar uses much more land than a coal-power plant, since each solar panel needs to face the sun and can鈥檛 be shaded by other panels. The 550 MW Desert Sunlight Solar Farm, for example, is one of the largest solar power plants in the world, with 8.8 million solar panels covering six square miles.

  • Where does the carbon for solar silicon smelting come from?

  • The Cerrejn open-pit mine in Columbia supplies 鈥淏lue Gem鈥?coal, a primary source of carbon for solar silicon smelters around the world. Metallurgical Coke鈥?(Metcoke) is a source of carbon for solar silicon smelting.
