Many of the other toxic chemicals and products in solar panels can also be recycled. Solar panels require a lot of space. Solar panels are not directly toxic, and having them on your property is not a health risk There are potentially harmful chemicals used in panel production, but responsible manufacturers will dispose of them properly Start comparing solar quotes from reputable installers on the Both are known to leach out of existing e-waste dumps into drinking water supplies. Solar panels significantly reduce the … Toxic materials in solar panels. During manufacture and after the disposal of solar panels, they release hazardous chemicals including cadmium compounds, silicon tetrachloride, hexafluoroethane and lead. While disposal of solar panels has taken place in regular landfills, it is not recommended because the modules can break and toxic materials can leach into the soil, causing problems with drinking water. This is not really news. Japan is also facing a growing solar waste problem. It’s a somewhat ironic concern from a proponent of nuclear power, which has a rather bigger toxic waste problem. How long will it take, and at what cost, to recycle 80 times that amount? Space Requirements. Rats received CIGS three times a week for one week, and then researchers examined lung tissue until three weeks after that. The rest of a solar panel is made of the aluminum frame, a glass cover, a couple layers called the encapsulant and backsheet which are made of various plastics, and the wiring. Beyond the inefficient use of these resources to begin with (in the process of making crystalline silicon from silicon, as much as 80 percentof the raw silicon is lost), there are numerous human health concerns directly related to the manufacture and disposal of solar panels. Tian called his country’s solar power industry “a ticking time bomb.”. As solar panels sit in dumps, the toxic metals they contain can leech out into the environment and possibly pose a public health hazard if they get into the groundwater supply. Around the globe, millions upon millions of solar panels have reached their use by dates; they can’t be recycled, which means they’re destined for the local dump. A solar panel is essentially made up of several sheets of silicon crystals called cells. The toxic chemicals in solar panels include cadmium telluride, copper indium selenide, cadmium gallium (di)selenide, copper indium gallium (di)selenide, hexafluoroethane, lead, and polyvinyl fluoride. Duggan Flanakin is the Director of Policy Research at the Committee For A Constructive Tomorrow. This byproduct can be used in manufacturing more polysilicon hence creating more solar panels. But, you say, solar energy is clean, green, and mean – and taking over the world one massive array at a time. While this seems like a contradiction to clean energy, it is not. According to… Copyright 2020 CFACT | All articles on this site may be republished without modification and with an attribution of the author and a link to CFACT.org within the body of the article. They also contain lead, cadmium, and other toxic (even carcinogenic) chemicals that cannot be removed without breaking apart the entire panel. In May 2018, Michael Shellenberger, a Time Magazine “Hero of the Environment” and Green Book Award Winner, wrote in Forbes that the problem of solar panel disposal will explode with full force in two or three decades and wreck the environment because it is a huge amount of waste which is not easy to recycle. For this reason, the whole solar panel is considered hazardous by many experts and governments, including the state of California , which is trying to prevent the flow of old solar panels to landfills. Shellenberger was citing comments, published in the South China Morning Post, from Chinese solar expert Tian Min, general manager of Nanjing Fangrun Materials, a recycling company in Jiangsu province that collects retired solar panels. Isn’t that what we have all been told? A 2018 report from the Institute of Energy Research suggests imposing a recycling fee on solar panel purchases. Heat is the random motion of atoms, molecules, and other subatomic particles… twitter.com/i/web/status/1…. Proponents like to cite the small size of the industry to date as a reason to ignore recycling requirements and costs in their business plans. Yet even their standards did not address costs. Beyond the clear misallocation of resources and energy market price distortions, there is a further environmental problem associated with solar panels. A potentially toxic problem. Solar panels contain lead, cadmium, and other toxic chemicals that cannot be removed without breaking apart the entire panel. Solar panels are composed of photovoltaic (PV) cells that convert sunlight to electricity. For decades, the solar industry benefited from generous federal, state, and local subsidies to increase its footprint. Cadmium indium gallium (di)selenide (CIGS) is another chemical in solar panels that is toxic to lungs. The scientists used a low, moderate and high dose of CIGS. A former Senior Fellow with the Texas Public Policy Foundation, Mr. Flanakin authored definitive works on the creation of the Texas Commission on Environmental Quality and on environmental education in Texas. He is author of the Kindle eBook "Tips of Surviving Graduate & Professional School.". Beyond the clear misallocation of resources and energy market price distortions, there is a further environmental problem associated with solar panels. Washington Post: Solar Energy Firms Leave Waste Behind in China. Solar panels often contain lead, cadmium, and other toxic chemicals that cannot be removed without breaking apart the entire panel. The truth can be brutal. The “Journal of Occupational Health” reported a study in which rats received doses of CIGS injected into the airway. As Cara Libby, senior technical leader of solar energy at the Electric Power Research Institute (EPRI), put it, “I’ve heard that [recycling] will have to be mandated because it won’t ever be economical.”. However, these concerns are trivi… “Solar panels create 300 times more toxic waste per unit of energy than do nuclear power plants. The silicon tetrachloride produced during the manufacturing process of solar panels is considered a toxic chemical; therefore, companies have to be recycled by companies to prevent environmental pollution and act as a cost-saving measure. Crystalline silicon is a key component of many solar panels. Licensed Photo taken by Spot Us Lungs also had spots that produced excessive fluid. Hazardous waste solar panels must be managed according to all applicable hazardous waste laws and regulations, including obtaining an authorization for conducting treatment. This lack of weight gain occurred at low, moderate and high doses. While generating electricity, a solar plant produces no emissions or waste. They can use this byproduct to create more polysilicon, and therefore more panels. When these panels enter landfills, valuable resources go … The production of crystalline silicon involves a byproduct called silicon tetrachloride. Additionally, silicon tetrachloride, a byproduct of producing crystalline silicon, is highly toxic. In a November 2016 article, Osamu Tomioka stated that Japanese solar panel waste will likely grow from the current 10,000 tons a year to 800,000 tons a year – and that just to recycle all of the waste produced through 2020 will take 19 years. The answer is no. The UN Intergovernmental Panel on Climate Change deems NF3 to be 17,200 times more potent than carbon dioxide as a greenhouse gas – meaning that even relatively minor quantities can have major impacts. But, absent a cogent PV recycling policy, the U.S. risks sending millions of solar modules and tons of toxics to landfill in the coming years. David H. Nguyen holds a PhD and is a cancer biologist and science writer. In the journal, “Progress in Photovoltaics," it reported that male and female rats that received CT through ingestion did not gain weight as they normally should have. The now-defunct, bankrupted Solyndra used its $535 million in guaranteed federal dollars to generate about 12.5 million pounds of hazardous waste, much of which was carcinogenic cadmium-contaminated waste, during its four years of operations. The solar panel manufacturing process does contribute to some greenhouse gas emissions–although minimal. When inhaled, CT also prevented normal weight gain and caused lung inflammation and lung fibrosis, a hardening of lung tissue. The typical residential panel only produces … The country’s inhabitants often pay the price. The toxic chemicals are a problem at the beginning of a solar panel's life -- during its construction -- and at the end of its life when it is disposed of. Lungs exposed to CIS produced high amounts of fluid. Silicon is the same element in sand, and is non-toxic. From low to high doses of inhaled CT, the weight of the lungs increased. Referencing a new report on the growing problem of old solar panel disposal, Holly Nicholas explains why green solutions aren't very green at all. Solar panels may be an appealing choice for clean energy, but they harbor their share of toxic chemicals. The study of rats in “Progress in Photovoltaics” showed that ingestion of moderate to high doses of copper indium selenide (CIS) prevented weight gain in females but not males. The deployment of solar has increased significantly in recent years in response to government subsidies and mandates. Worse, rainwater can wash many of these toxics out of the fragments of solar modules over time. 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 panels may be an appealing choice for clean energy, but they harbor their share of toxic chemicals. A federal disposal and decommissioning fund would then dispense funds to state and local governments to help pay for removal and recycling or long-term storage of solar panel waste. Cadmium telluride (CT) is a highly toxic chemical that is part of solar panels. While solar panels, like other electronics, contain and are manufactured using toxic materials, measures can be taken to minimize negative effects. Copyright 2021 Leaf Group Ltd. / Leaf Group Media, All Rights Reserved. Moderate to high doses of inhaled CT proved lethal. These spots worsened as time went on after the one week of exposure. Emissions from a coal plant cause harmful air and carbon pollution, while nuclear power creates waste product that remain extremely toxic to humans for millions of year. “Approximately … Silicon tetrachloride is highly toxic, killing plants and animals. To be clear, damaged solar panels leaching toxic materials isn’t an enormous risk, given how much solar panels help address the near-term dangers … The average lifespan of a solar panel is about 20 years, but high temperatures (as in the Mojave Desert) can accelerate the aging process for solar cells, and snow, dust, and other natural events (tornadoes, earthquakes),can cause material fatigue on the surface and in the internal electric circuits – gradually reducing the panel’s power output. Journal of Occupational Health: Subacute Pulmonary Toxicity of Copper Indium Gallium Diselenide Following Intratracheal Instillations into the Lungs of Rats. Moderate to high doses of inhaled CIS increased the weight of a rat’s lungs and increased lung fibrosis. This guidance was prepared by the Regulatory Assistance Office of the Department of Toxic Substances Control (DTSC) and answers frequently asked questions received by the DTSC electronic waste enforcement team. Beyond the clear misallocation of resources and energy market price distortions, there is a further environmental problem associated with solar panels. A brief history of his multifaceted career appears in his book, "Infinite Galaxies: Poems from the Dugout. Solar panels contain toxic metals like lead, which can damage the nervous system, as well as cadmium, a known carcinogen. According tocancer biologist David H. Nguyen, PhD, toxic chemicals in solar pa… While disposal of solar panels has taken place in regular landfills, it is not recommended because the modules can break and toxic materials can leach into the soil, causing problems with drinking water. c-Si cells are currently 95% of the market.. Those countries mass-produce “clean energy” solar panels but do not regulate how toxic waste is dumped into the environment. Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants. As the State of Oregon reports, solar panels are safe and beneficial because they don't produce harmful greenhouse gases or toxic air that some other energy sources emit. About 80% of a solar panel module can be … All doses resulted in lungs that had spots that were inflamed, meaning they were damaged. Beyond the inefficient use of these resources to begin with (in the process of making crystalline silicon from silicon, as much as 80 percentof the raw silicon is lost), there are numerous human health concerns directly related to the manufacture and disposal of solar panels. ", Does ocean activity have more of a role in temperatures than previously thought? Stanford Magazine: The Possibility of a Solar-Powered Nation, Toxicology and Applied Pharmacology: Comparative Pulmonary Absorption, Distribution, and Toxicity of Copper Gallium Diselenide, Copper Indium Diselenide, and Cadmium Telluride in Sprague–Dawley Rats. [Similar fees help recover costs for nuclear waste disposal and coal mine reclamation for bankrupt facilities.]. Yet these generous subsidies ignore the costs of disposal of solar panel waste. Introduction. His specialty is tumor biology. Solar panels generally last about 20 years. This informal guidance serves to make available on the web, answers to frequently asked questions about solar panels. According tocancer biologist David H. Nguyen, PhD, toxic chemicals in solar pa… And bankruptcies have been all too common in an industry that has relied so heavily on disappearing subsidies. But the deeper truth is that the costs for solar waste disposal can be huge. In a typical silicon solar cell, the amount of toxic chemicals is negligible, and tests done on these panels have revealed levels of toxic chemicals far beneath the standards set forth by the EPA. Cadmium is a particular toxic waste problem: The fact that cadmium can be washed out of solar modules by rainwater is increasingly a concern for local environmentalists like the Concerned Citizens of Fawn Lake in Virginia, where a 6,350 acre solar farm to partly power Microsoft data centers is being proposed. @BigJoeBastardi thinks it might,… twitter.com/i/web/status/1…, Just to be safe... pic.twitter.com/JtFAUtiJ3a, No, not the Al Pacino film from 1995. Each panel is a veritable toxic cocktail of gallium arsenide, tellurium, silver, crystalline silicon, lead, cadmium and other heavy metals. Solar panels generate 300 times more toxic waste per unit of energy than nuclear power plants. Solar panels are a veritable toxic cocktail of gallium arsenide, tellurium, silver, crystalline silicon, lead, cadmium, and heavy earth material. The solar industry cannot claim to be a clean energy source if it leaves a trail of hazardous waste. These two intervals are times when the toxic chemicals can enter into the environment. Solar panels often contain lead, cadmium, and other toxic chemicals that cannot be removed without breaking apart the entire panel. Beyond the inefficient use of these resources to begin with (in the process of making crystalline silicon from silicon, as much as 80 percentof the raw silicon is lost), there are numerous human health concerns directly related to the manufacture and disposal of solar panels. He also has a strong interest in the deep intersections between social injustice and cancer health disparities, which particularly affect ethnic minorities and enslaved peoples. Solar panels contain heavy metals such as silver, copper, lead, arsenic, cadmium and selenium. The type of solar panels that are by far the most common on homes are made of crystalline silicon (c-Si). While the European Union has long required solar panel manufacturers to collect and dispose of solar waste, in the U.S. until very recently only Washington State had any recycling requirements. Whether the lead contained within perovskite solar cells represents a tangible risk to humans, animals and the environment is being debated, however, some scientists are now searching for non-toxic materials which could replace the lead in perovskite solar … Such environmental pollutants, which harm people, are a major problem for people in China and other countries. The simple truth is that it is past time for a real accounting of the overall costs to the public and to the environment of a massive increase in the use of solar panels as compared, for example, of increased reliance on non-intermittent technologies like nuclear energy and natural gas. What’s in a Solar Panel? The Associated Press had reported in 2013 that the heavily subsidized solar industry was creating millions of pounds of polluted sludge and contaminated water that is often shipped landfills often hundreds of miles away. Solar panels can be recycled but the cost of recycling is generally more than the economic value of the material recovered. Another real concern is the vast increase in the use of nitrogen trifluoride (NF3) in the construction of solar panels – up 1,057 percent over the past 25 years. Solar panels are composed of photovoltaic (PV) cells that convert sunlight to electricity. Researchers with the Electric Power Research Institute (EPRI) undertook a study for U.S. solar-owning utilities to plan for end-of-life and concluded that solar panel “disposal in “regular landfills [is] not recommended in case modules break and toxic materials leach into the soil” and so “disposal is potentially a major issue.” Don’t throw them away or dump them because they can leach toxic chemicals into the environment. The state goes on to add that the potentially hazardous components used to make solar panels don't pose a risk that's \"different or greater than the risks found routinely in modern society.\" The most important health and safety hazards come from the use of dangerous materials during the making of solar cells. Another study of CIS on rats, reported in “Toxicology and Applied Pharmacology,” revealed that inhaling CIS caused rats to develop abnormal growths in their lungs. When these panels enter landfills, valuable resources go to waste. One of the toxic chemicals involved with solar panels is not what’s in the panels but is a byproduct of their production. But how much of a fee would be needed? Things may be changing. And manufacturers also use toxic chemicals in some of these panels.
