With the aging out of the first generation of photovoltaic systems, recycling solar panels growing in importance as a participant in the green energy lifecycle. The solar panel material is made of glass, aluminum and traces of other rare metals such as silver and indium, which should not find their way to the landfill. The most sophisticated mechanical and thermal technologies are employed at the major solar panel recycling companies where these materials are separated. The solution is a closed-loop system in which silicon can be re-used in manufacturing new cells using the recovered silicon. Nonetheless, the business is not without troubles; the recovery price is usually higher than the price of raw materials. This is the reason why expert recycling firms of solar panels are supporting the idea of Extended Producer Responsibility legislations so that sustainable disposal financing can be made at the beginning.
