In various sorting steps the glass and copper strings can then be separated from the EVA foil. “If we don’t mandate recycling, many of the modules will go to landfill,” said Arizona State University solar researcher Meng Tao, who recently authored a review paper on recycling silicon solar panels, which comprise 95 percent of the solar market. In order to be prepared for the deluge in 10 – 15 years, investment needs to happen now in optimizing the PV recycling techniques, designing and building the most efficient machinery for the job. PV Cycle, a nonprofit dedicated to solar panel take-back and recycling, collects several thousand tons of solar e-waste across the European Union each year, according to director Jan Clyncke. “It’s on the order of a 10-to-1 ratio.”. Solar panels are an increasingly important source of renewable power that will play an essential role in fighting climate change. Almost all (95%) of the glass can be reused, while all external metal parts are used for re-molding cell frames. As of mid 2014 there was already around 8 million tonnes of solar panels installed that will one day need to be recycled. Tao and his colleagues estimate that a recycler taking apart a standard 60-cell silicon panel can get about $3 for the recovered aluminum, copper, and glass. Although the majority of a PV panel is made of glass, when recycled correctly, many materials can be separated out and used again in the manufacture of other products, including new PV panels: Different techniques are used to extract different materials from the different types of solar modules, whether they are silicone-based or thin film-based technologies, whether CdTe (Cadmium Telluride) or CIGS (Copper, Indium, gallium, Selenium). The material on this site may not be reproduced, distributed, transmitted, cached or otherwise used, except with the prior written permission of Condé Nast. Certain processes also use upstream shredding to access the materials more easily. The advantage of creating a PV-specific recycling technique is that this avoids extra costs as a result of unnecessary sorting, and it also avoids contaminating the panels with other materials, by using the wrong process when solar PV is recycled by traditional recyclers, adding extra steps to the process. In a manual or automated process, the frame, junction box and cables are removed to be processed in separate recycling lines. Most notably, Washington state, under the leadership of Governor Jay Inslee, … The firm already receives a trickle of panels, in cases where panels were damaged during delivery or installation, or were factory seconds, which accounts for 99% of their recycling. Recovering the most valuable materials from one, including silver and silicon, requires bespoke recycling solutions. The Solar Panel Recycling Market will grow by USD 238.30 mn during 2020-2024 The rest, he says, go to landfills or are exported overseas for reuse in developing countries with weak environmental protections. By 2050, the International Renewable Energy Agency projects that up to 78 million metric tons of solar panels will have reached the end of their life, and that the world will be generating about 6 million metric tons of new solar e-waste annually. A small number of dedicated solar PV recyclers are trying to do this. Used panels are also sold to developing world countries that want to purchase them inexpensively despite their reduced ability to produce energy. In addition to developing better recycling methods, the solar industry should be thinking about how to repurpose panels whenever possible, since used solar panels are likely to fetch a higher price than the metals and minerals inside them (and since reuse generally requires less energy than recycling). “What we call for is what we name a high-value, integrated recycling system,” Heath told Grist. However, both he and Tao are concerned that various US recyclers are selling second-hand solar panels with low quality control overseas to developing countries. The recycling process of silicon-based PV panels starts with disassembling the actual product to separate aluminium and glass parts. (480) 482-7050 About Us Co-founder Alex Hessler explains how they built the concept and why they use the Verizon Visa® Card to help with product development. Photograph: Richard Newstead/Getty Images, Voluntary, industry-led recycling efforts, Circular Business Models for the Solar Power Industry, ✨ Optimize your home life with our Gear team’s best picks, from. Recyclers often take off the panel’s frame and its junction box to recover the aluminum and copper, then shred the rest of the module, including the glass, polymers, and silicon cells, which get coated in a silver electrode and soldered using tin and lead. To revist this article, visit My Profile, then View saved stories. In subsequent steps the individual materials are further refined. The number of solar panels reaching end of life in Europe doubles every year; 35,000 metric tonnes of solar panel e-waste is expected in 2020 alone. Materials extracted from the recycled panels are used directly for new panels. “We believe the big blind spot in the US for recycling is that the cost far exceeds the revenue,” Meng said. Regardless, solar panel waste disposal is a problem that needs to be addressed. And if we fail to develop those solutions along with policies that support their widespread adoption, we already know what will happen. As lead study author Garvin Heath explains, such processes might include using heat or chemical treatments to separate the glass from the silicon cells, followed by the application of other chemical or electrical techniques to separate and purify the silicon and various trace metals. And because solar panels contain toxic materials like lead that can leach out as they break down, landfilling also creates new environmental hazards. When solar panels reach their end of their life today, they face a few possible fates. Used panels are also sold to developing world countries that want to purchase them inexpensively despite their reduced ability to produce energy. All rights reserved. Contrarily, Si-based panels are poor of valuable materials, and their recycling cost is always higher than the landfilling one, making recycling an unfavorable economic option . If a solar panel’s more valuable components—namely, the silicon and silver—could be separated and purified efficiently, that could improve that cost-to-revenue ratio. The very few first solar panels were manufactured in the 1970s, and for the most part, these very early solar pioneers have not yet dismantled their old solar arrays that are still producing after 45 years. Solar panels can be recycled but the cost of recycling is generally more than the economic value of the material recovered. It’s not right throwing that responsibility on the consumer, and that’s where we’re at right now.”. Only 1% are solar relics from those early days of the solar pioneers, facing their true end-of-life. Strategies for recycling of solar panels Date: July 16, 2020 ... Based on their findings, the authors recommend research and development to reduce recycling costs … Building insulation is a big market for the glass, after it has been recycled into glass insulation and glass foam, a widely used non-flammable thermal insulation material in Europe. Recycling solar panels is a topic which will be a lot more prevalent as the initial ‘wave’ panels begin to reach their end of life. Solar panels can be recycled but the cost of recycling is generally more than the economic value of the material recovered. Thankfully back in 2014 the pair from Solar Maintenance and Renewable Technologies (SMART), Clive Fleming and David Galloway recognised the lack of solar panel recycling processes in Australia and have worked together to launch Reclaim PV Recycling. Solar panel subsidy programs ignore the costs of disposal of solar panel waste. But we’ll need to develop one soon, because the solar e-waste glut is coming. Our solar recycling experts field this question before major decommissioning planning and physical tear-down projects. As is the case with recycling, the EU is out in front on this: Through its Circular Business Models for the Solar Power Industry program, the European Commission is funding a range of demonstration projects showing how solar panels from rooftops and solar farms can be repurposed, including for powering ebike charging stations in Berlin and housing complexes in Belgium. Additionally, Veolia, a French water and waste company, opened Europe’s first solar panel recycling plant in 2018. https://www.goodnewsnetwork.org/first-solar-solar-panel-recycling-program In fact, the recycling process, the cost of technologies, and the materials used in solar cells play a significant role in the percentage of recycled PV cells. After recycling silicon solar panels 100% of the metal, 85% of the silicon modules are given new lives in other products or to make other solar panels. Solar panels are composed of photovoltaic (PV) cells that convert sunlight to electricity. According to studies, the life expectancy of solar panels is about 30 years before decommissioning.. During the life of photovoltaic panels, a 20 per cent decrease in power capacity might occur. https://news.dualsun.com/solar-technology/recycling-solar-panels In another recent review paper, a team led by National Renewable Energy Laboratory scientists calls for the development of new recycling processes in which all metals and minerals are recovered at high purity, with the goal of making recycling as economically viable and as environmentally beneficial as possible. When these panels enter landfills, valuable resources go to waste. This way, the panels’ waste and impact on the environment is minimized with only a marginal increase in solar panel price for consumers. Let’s take a look at what the plans are for trying to minimise the environmental impact and maximise the value of a used solar panel. Wired may earn a portion of sales from products that are purchased through our site as part of our Affiliate Partnerships with retailers. They are also complex pieces of technology that become big, bulky sheets of electronic waste at the end of their lives—and right now, most of the world doesn’t have a plan for dealing with that. Regardless, solar panel waste disposal is a problem that needs to be addressed. On the back of the panel, a junction box contains copper wiring that channels electricity away as it’s being generated. Integrated refers to a recycling process that can go after all of these materials, and not have to cascade from one recycler to the next.”. The breakthroughs and innovations that we uncover lead to new ways of thinking, new connections, and new industries. “So eventually, you’re dumping your problem on a poor country.”. Solar panels can be recycled at general-purpose glass recycling facilities or at one of the new recycling facilities that are popping up that specialize in recycling solar panel components. How long do solar panels last? It is the essential source of information and ideas that make sense of a world in constant transformation. “Right now, we’re pretty confident the number is around 10 percent of solar panels recycled,” said Sam Vanderhoof, the CEO of Recycle PV Solar, one of the only US companies dedicated to PV recycling. It’s all held together in an aluminum frame. © 2021 Condé Nast. But before that’s going to happen, US lawmakers need to recognize that the problem exists and is only getting bigger, which is why Vanderhoof spends a great deal of time educating them. Recycling solutions for these non-silicon based PV are based on recycling techniques from waste water treatment or battery recycling, for example. In the United States, it’s the Wild West: With the exception of a state law in Washington, the US has no solar recycling mandates whatsoever. Ad Choices, Solar Panels Are Starting to Die, Leaving Behind Toxic Trash. While solar panels currently make up just a small amount of e-scrap, the need for solar panel disposal will rise dramatically over the next few decades as projects being built today reach the end of their useful lives. To keep family and friends connected during COVID-19, visual effects company, Invisible Thread, developed an augmented reality application that would enhance video communication to keep people more authentically connected during a time of separation. In France, 53,000 tonnes of end-of-life solar panels wound up on the waste market in 2016 and 84,000 tonnes in 2017. As the oldest ones expire, get ready for a solar e-waste glut. Under EU law, producers are required to ensure their solar panels are recycled properly. “And what do we do when they start to fail? That figure includes solar panels that have reached the end of their life but also those that were decommissioned early because they were damaged during a storm, had some sort of manufacturing defect, or got replaced with a newer, more efficient model. This story originally appeared on Grist and is part of the Climate Desk collaboration. These kinds of quantities won’t be recyclable without companies preparing now by setting a standard for the industry. A solar panel is essentially an electronic sandwich. A surprising variety of materials can be extracted from old solar, according to PV CYCLE. When the wiring and the inverters are included in the recycling also, even more materials can also be recycled, like the plastics in the cables and junction boxes. Most solar manufacturers claim their panels will last for about 25 years, and the world didn’t start deploying solar widely until the early 2000s. “We need to face the fact that solar panels do fail over time, and there’s a lot of them out there,” he said. The WIRED conversation illuminates how technology is changing every aspect of our lives—from culture to business, science to design. “High-value means we want to recover all the constituent materials that have value from these modules. A surprising variety of materials can be extracted from old solar, according to PV CYCLE. In Japan, India, and Australia, recycling requirements are in the works. (Because the vast majority of that mixture by weight is glass, the resultant product is considered an impure, crushed glass.) Some PV researchers want to do even better than that. The Lifetime of Solar Panels. Voluntary, industry-led recycling efforts are limited in scope. WIRED is where tomorrow is realized. But the company recently received some new equipment from its European partners that can do “95 plus percent recapture,” he said, while separating the recaptured materials much better. In CdTe and CIGS panels, the materials are separated using a mainly chemical process. The EU model of having producers finance the take-back and recycling of solar panels might be a good one for the U.S. to emulate. The European Union requires solar companies to collect and recycle their panels, with the cost of recycling built into the selling price. The plant’s supply is provided through a contract with the solar recycling organization PV Cycle France. Image credits: via FlickR(1,2,3) under CC license. Photovoltaic panels are a boon for clean energy but are tricky to recycle. A question that most people have in mind when considering solar panels. As a result, a fairly small number of panels are being decommissioned today. From 2010 to 2019, net summer solar PV power capacity in the U.S. alone grew from 393 MW to 35,571 MW, according to the EIA. Washington state is taking an even more proactive approach: last year, it passed legislation that requires solar panel manufacturers to have a recycling plan for their products. (480) 482-7050 According to Vanderhoof, Recycle PV Solar initially used a “heat process and a ball mill process” that could recapture more than 90 percent of the materials present in a panel, including low-purity silver and silicon. While the latter number is a small fraction of the total e-waste humanity produces each year, standard electronics recycling methods don’t cut it for solar panels. Solar energy is now cheaper than coal and natural gas in most nations, according to an October 2020 report from the International Energy Agency.Decreasing costs for solar photovoltaics (PV), along with efforts to minimize non-hardware costs, help explain the increased solar capacity coming online to the electric grid.. Silicon Based Solar Panel Recycling. Solar has a useful life of half a century, and is such a new industry that we’ve yet to see much end-of-life recycling, but it is a responsibility that must be addressed as time goes on. At a typical e-waste facility, this high-tech sandwich will be treated crudely. Find Out Now. this avoids extra costs as a result of unnecessary sorting, Does Your House Qualify for Solar? Lange pointed out that many resellers of panels will no longer be in the market when today’s panels are ready to be recycled, and she believes that it is crucial to develop an industry-managed scheme that is dedicated to providing a cost-effective long-lived solution to meet these needs. It accounts for about half of the energy, carbon footprint, and cost to produce PV modules, but only a small portion of … In … Tao and his colleagues estimate that a recycler taking apart a standard 60-cell silicon panel can get about $ For now, the future of solar panel recycling is in the hands of the states. But like any other industry, the PV recycling industry takes volume to optimise the processes and attract the investment needed to improve the technology. How AR is Enhancing Human Connectivity During COVID-19. Vanderhoof, meanwhile, says that the cost of recycling that panel in the US is between $12 and $25—after transportation costs, which “oftentimes equal the cost to recycle.” At the same time, in states that allow it, it typically costs less than a dollar to dump a solar panel in a solid-waste landfill. Use of this site constitutes acceptance of our User Agreement (updated as of 1/1/21) and Privacy Policy and Cookie Statement (updated as of 1/1/21) and Your California Privacy Rights. The glass laminate is then shredded or milled to access the different layers of a PV module. How much does solar panel disposal cost? “And those countries typically don’t have regulations for electronics waste,” Tao said. In a next step the recovered materials can be further refined, using both chemical and mechanical techniques. For the solar recycling industry to grow sustainably, it will ultimately need supportive policies and regulations. At a recycling plant in Ohio, next to the company’s manufacturing facility, First Solar uses custom technology to disassemble and recycle old panels, recovering 90% of the materials inside. Recycle PV Solar also recertifies and resells good-condition panels it receives, which Vanderhoof says helps offset the cost of recycling. Even its strongest advocates admit that economical recycling of solar panels is at least two decades away, while reusing deteriorating solar panels can be likened to giving your teenager a $500 car… We Recycle Solar's solar panel recycling program helps you to achieve maximum value recovery with our certified, secure solutions for recycling solar panels. The filling is a thin layer of crystalline silicon cells, which are insulated and protected from the elements on both sides by sheets of polymers and glass. The individual materials used in silicon-based PV modules are separated and refined step by step refined in a mainly mechanical process. Averting A Waste Crisis – For Planet And Profit. Three years after opening, the facility recycles more than 50,000 solar panels a year. One company that is looking ahead to the day when old PV starts getting trucked in to the scrap yard is PV CYCLE, based in Europe and now recycling solar panels from Spain, Germany, Italy, Belgium, Greece, and the Czech Republic. The good news is that the industry has recycling rates of up to 90 per cent for silicon-based modules and … Even when recycling happens, there’s a lot of room for improvement. Solar panel recycling is a pressing issue that could evolve into a major waste crisis if necessary action isn’t taken. Veolia, which runs the world’s only commercial-scale silicon PV recycling plant in France, shreds and grinds up panels and then uses an optical technique to recover low-purity silicon. The silicon flakes, a combination of EVA laminate, semiconductor and metals are sent to micro-recycling, applying thermal processes to further split the materials, or energy recovery. The authors focused on the recycling of crystalline silicon, a material used in more than 90% of installed PV systems in a very pure form.
