Toxic Waste From Solar Panels

Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants.

Toxic waste from solar panels. The international renewable energy agency estimated that there were about 250 000 metric tons of solar panel waste in the world at the end of 2016 and that the figure could reach 78 million metric tons by 2050. When these panels enter landfills valuable resources go to waste. Solar panels produce tons of toxic waste literally. Solar panels are composed of photovoltaic pv cells that convert sunlight to electricity.

Solar panels contain lead cadmium and other toxic chemicals that cannot be removed. A closer look at solar panels opens a wide array of questions that need answers. Solar panels create 300 times more toxic waste per unit of energy than do nuclear power plants. Worse rainwater can wash many of these toxics out of the fragments of solar modules over time.

And because solar panels contain toxic materials like lead that can leach out as they break down landfilling also creates new environmental hazards. If solar and nuclear produce the same amount of electricity over the next 25 years that nuclear produced in 2016 and the wastes are stacked on football fields the nuclear waste would reach the height of the leaning tower of pisa 53 meters while the solar waste would reach the height of two. Environmental scientists and solar industry leaders are raising the red flag about used solar panels which contain toxic heavy metals and are considered hazardous waste. They also contain lead cadmium and other toxic even carcinogenic chemicals that cannot be removed without breaking apart the entire panel.

And because solar panels contain toxic materials like lead that can leach out as they break down landfilling also creates new. With recycling expensive. While solar panels like other electronics contain and are manufactured using toxic materials measures can be taken to minimize negative effects. Photo by andreas gücklhorn on unsplash bill wirtz.

Silicon tetrachloride mentioned above as one of the most toxic chemicals involved in the manufacturing of panels is usually recycled by manufacturers as a cost saving measure. Solar photovoltaic panels whose operating life is 20 to 30 years lose productivity over time. Solar panels create 300 times more toxic waste per unit of energy than do nuclear power plants.
