In general, all photovoltaic panels are recyclable.
Indeed, there are risk-free procedures for silicon-based panels as well as for thin-film panels containing cadmium. Moreover, recycling is regulated by the European Directive 2012/19/EU on waste electrical and electronic equipment, which is transposed into national law by the law of 9 June 2022 on waste electrical and electronic equipment: this framework currently requires at least 80% of the mass of a photovoltaic panel to be prepared for reuse or recycled, and 85% of the mass to be recovered.
The recycling rate of photovoltaic modules is nevertheless close to 100%, considering that the modules are generally composed mainly of glass, aluminium and other metals. Net modules usually contain very limited amounts of synthetic materials, such as silicon or other minerals. However, it is technically possible to recycle these elements, even if the processes for extracting them are not yet cost-effective. Thus, these materials are currently mainly used for thermal recovery.
