When the life cycle of a photovoltaic system ends, what are the regulations for disposal? Thankfully, when it comes to photovoltaic panels disposal involves a recovery system that reduces or completely eliminates waste. Recycle i solar panels has rules and those who have to get rid of the old system can request special ones incentives.
In 2010 the photovoltaic Italy grew by 215% in the quantity of plants and by 324% in terms of installed power: a strong growth in renewables, despite the uncertainties about regulations. We need to focus on a not inconsiderable detail: recovery and it disposal of panels exhausted. In 2011, 50,000 were thrown away solar panels. A figure, according to experts, destined to grow exponentially: the exhaustion of the productive life cycle of a photovoltaic panel is about 20/25 years and the first installations began in the 90s.
Finally, it will now be possible to cause less damage to the environment thanks to the new European directive that covers the old ones photovoltaic panels such as Waste from electrical and electronic equipment (WEEE). The indication of the European Union referred to in Art. 11.6 (a) of the ministerial decree of 5 May 2011, the so-called IV Conto Energia, provides that the producers of photovoltaic modules provide their customers guarantees on the recycling of panels to be able to access the incentives provided.
There are incentives for setting up solar panels and incentives for the disposal. With the revision of the WEEE directive, the European Union introduces this type of equipment, so that the solar panels, once their life cycle is over, will fall into category 4 of waste from "electrical and electronic equipment". In fact, the maximum deadline within which the manufacturing companies must join a system or consortium that guarantees therecycling of photovoltaic modules, in order to ensure its customers access to incentives.
The modalities of the recycling depend on the type of panel and the materials that compose it.
There are two prevalent technologies:
-Solar panels in crystalline silicon whose modules are disassembled and the other materials (tempered glass, silicon and aluminum cells) recovered separately.
-Solar panels for modules in thin film CdTe, which uses tellurium and cadmium, very toxic and more difficult to manage materials.
Good for the economy and the environment: give it to you photovoltaic systems, therefore, in addition to glass, aluminum, also indium, gallium, selenide can be obtained, at the risk of exhaustion due to the exponential demand. With their life, solar panels have given the world clean electricity and have reduced CO2 emissions.
At the end of its cycle, the photovoltaic returns precious raw materials to the environment. With this initiative, no more panels left to themselves but above all it is hoped that with this renewed mechanism, the requests forincentives for photovoltaics are increasingly numerous and less uncertain.
