Have you ever thought about the expiration date of solar panels? The Kiran C. Patel College of Global Sustainability (PCGS) at the University of South Florida recently posted a bit of information on the lifetime of solar power panels, and the need to include them in recycling plans:
Photovoltaic (PV) solar panels are made with heavy metals and other toxic materials. They cannot simply be thrown away, because they are so harmful to the environment and to people. That is precisely why PCGS Alumna Karla Kemp is talking about the End of Life Cycle Management of Solar Panels at the Renewable Energy World International conference on December 14th, in Orlando, FL. Photovoltaic cells (otherwise known as solar cells) are cells that convert sunlight directly into electricity. PV solar panels became widely available between the 1970’s and the 1990’s and with an average lifespan of 25-30 years. Now, we are seeing the first big group of them reaching the end of life.
“With high level of toxicity involved, standard end of life waste management practices are not feasible, leaving a serious problem for waste management and public health concerns,” Karla said. “Recycling options are dependent on factors such as regulatory framework, panel design, recycling process, material recovery and price, thus creating the necessity for uniform regulatory practices.”
End of life management for these PV solar panels is essential to further the renewable energy movement. “Research and development in new technological advances will enable significant improvements in technological efficiency, availability, and successfully be able to eliminate the reliance on fossil fuels,” Karla said. “[All] while eliminating potential environmental impacts, enhancing the market share of renewable power.” See here for the news post.
