Recycling Old Solar Panels for Raw Materials

With the global expansion of solar energy use, the need to recycle old solar panels is increasing to transform them into a vital source of raw materials. These panels contain high-value metals such as silver, copper, silicon, and aluminum, with over 85% of the panel's weight recoverable. However, current recycling capabilities do not yet cover the quantities expected as the lifespan of many panels approaches its end—especially considering that over 8 billion panels are installed worldwide, with a total capacity exceeding 3 terawatts. Europe, led by Germany, is the most advanced in establishing recycling regulations, while challenges remain in disassembling materials and their resistance to weather conditions, which raise processing costs. The sector is currently experiencing a technological boom, with improvements in processing speed and cost reduction aimed at more efficient material recovery and the preservation of environmental and public health.
