A redemption request must be submitted and the solar modules have to be removed, then First Solar picks them free of charge and recycles them. About 90 percent of the materials in a withdrawn module can be reused. The solar energy has a substantial role in the transformation of the energy supply to renewable energy. Many of the materials needed for production of solar modules are rare and the mining as well as the manufacture causes environmental pollution. Hence, recycling of solar panels is an important step towards a more sustainable solar industry.
