What Happens to PV Panels When Their Life Cycle Ends


The energy industry has been experiencing a radical change and the gradual shift towards renewable energy sourcing is more than evident. Nevertheless, not all that looks sustainable stays that way upon the end of its life cycle. At least that is the most common worry regarding photovoltaic (PV) solar panels. They are a sustainable source of energy, dependant only on solar radiation, and capable of delivering electricity to our homes. However, what happens to solar panels when they fail to perform efficiently? Explore their journey through the recycling process in the infographic below:

The Lifetime of Solar Panels


How long do solar panels last? A question that most people have in mind when considering solar panels. 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. Between the first 10 to 12 years, the maximum decrease in efficiency is 10 per cent, and 20 per cent when reaching 25 years. These figures are guaranteed by the majority of manufacturers.


Still, experience shows that, in reality, the efficiency drops by merely 6 to 8 per cent after 25 years. The lifespan of solar panels may thus be much longer than officially stated. The lifespan of high quality PV panels may even reach 30 to 40 years, and be still functional afterwards, though with decreasing efficacy.


Disposal of Solar Panels


From a regulatory aspect, PV panel waste still falls under the general waste classification. A sole exception exists at EU-level, where PV panels are defined as e-waste in the Waste Electrical and Electronic Equipment (WEEE) Directive. The PV panel waste management is thus regulated by this directive, additionally to other legal frameworks.


The solar cells manufacturers are bound by law to fulfil specific legal requirements and recycling standards in order to make sure that solar panels do not become a burden to the environment. That is when technologies to recycle solar panels started emerging.

Photovoltaic producers collaborated with governmental institutions and have come up with a few ways to tackle solar waste.

Solar Panel Waste


In fact, if recycling processes were not put in place, there would be 60 million tons of PV panels waste lying in landfills by the year 2050; since all PV cells contain certain amount of toxic substances, that would truly become a not-so-sustainable way of sourcing energy.

The common belief of solar panels not being recyclable is, therefore, a myth. It is, however, a process that needs time to be widely implemented and requires further research to reach its full potential of adequately recycling all solar panel components. For that reason, it is necessary that designing and recycling units collaborate closely so that the ability to recycle is ensured by mindful eco-designs.


Solar Panel Recycling Processes


There are two main types of solar panels, requiring different recycling approaches. Both types—silicon based and thin-film based—can be recycled using distinct industrial processes. Currently, silicon based panels are more common, though that does not mean that there would not be great value in the materials of thin-film based cells.


Research studies conducted on the topic of recycling solar panels have resulted in numerous technologies. Some of them even reach an astonishing 96% recycling efficiency, but the aim is to raise the bar higher in the future.


Silicon Based Solar Panel Recycling


The recycling process of silicon-based PV panels starts with disassembling the actual product to separate aluminium and glass parts. Almost all (95%) of the glass can be reused, while all external metal parts are used for re-molding cell frames. The remainder materials are treated at 500°C in a thermal processing unit in order to ease up the binding between the cell elements. Due to the extreme heat, the encapsulating plastic evaporates, leaving the silicon cells ready to be further processed. The supporting technology ensures that not even this plastic is wasted, therefore it is reused as a heat source for further thermal processing.


After the thermal treatment, the green hardware is physically separated. 80% of these can readily be reused, while the remainder is further refined. Silicon particles—called wafers—are etched away using acid. Broken wafers are melted to be used again for manufacturing new silicon modules, resulting in 85% recycling rate of the silicon material.


Thin-Film Based Solar Panel Recycling


In comparison, thin-film based panels are processed more drastically. The first step is to put them in a shredder. Afterwards, a hammermill ensures that all particles are no larger than 4-5mm, which is the size where the lamination keeping the inside materials together breaks, and hence can be removed. Contrary to silicon-based PV panels, the remaining substance consists of both solid and liquid material. To separate these, a rotating screw is utilised, which basically keeps the solid parts rotating inside a tube, while the liquid drips into a container.


Liquids go through a precipitation and dewatering process to ensure purity. The resulting substance goes through metal processing to completely separate the different semiconductor materials. The latter step depends on the actual technology used when producing the panels; however, on average 95% of the semiconductor material is reused.


Solid matters are contaminated with so-called interlayer materials, which are lighter in mass and can be removed through a vibrating surface. Finally, the material goes through rinsing. What is left behind is pure glass, saving 90% of the glass elements for easy re-manufacturing.


The Future Benefits of Solar Waste Management


Now that we know that solar panels can be recycled, the question is what other benefits it brings to the economy—if any. Obviously, a proper solar panel recycling infrastructure will need to be established to manage the large volumes of PV modules that will be disposed in near future. Once that is in place, we’ll be witnessing several positive factors and new opportunities within the economy.


Not only will PV recycling create more green job opportunities but also approximately £11 billion in recoverable value by 2050. This influx will make it possible to produce 2 billion new panels without the need to invest in raw materials. This means that there will be the capacity of producing around 630 GW of energy just from reusing previously used materials.


Thanks to constant solar energy price drops, more and more households and businesses choose to invest in solar power systems. As a result, even more economic opportunities in the solar cell recycling sector will emerge.

A combination of EPA and USDA funding has resulted in numerous changes throughout the city, including free commercial recycling service, residential recycling carts and organics infrastructure. Providence, Rhode Island, is starting to see tangible results from multiple organics and recycling programs funded by federal grants. This work was spurred by $3.34 million from the U.S. EPA’s Solid Waste Infrastructure for Recycling grant program awarded in 2023, as well as $255,850 from a U.S. Department of Agriculture grant awarded in 2024. Now, multiple years in, the city has funded new vehicles, carts and other infrastructure. Back in November 2023, Mayor Brett Smiley described the EPA funding as a big opportunity to advance sustainability efforts. “By helping divert food waste, in particular, from the waste stream we can extend the life of our Central Landfill, but also help meet our climate justice goals,” he said at a November 2023 Northeast Recycling Council event. Smiley noted this would also help address recycling issues. “We know that we’ve got a major education gap to fill with residents and business owners. The recycling rates in the city of Providence are quite low [and] there’s a very clear equity gap in terms of which neighborhoods recycle and how.” Commercial recycling One unique aspect of Providence’s grant-funded programs is free commercial recycling service, which is still coming to fruition. In his NERC speech, Mayor Smiley noted this idea was driven in part by “a problem with overflowing dumpsters” that “degrades the quality of life” in certain commercial areas with a lot of restaurants. The SWIFR grant, which has funding until January 2027, helped fund the purchase of a rearload recycling collection truck for approximately $200,000. This truck is run by the city’s Department of Public Works and initially focused on offering free service in two neighborhoods. Federal Hill and the West End were chosen for their high density and proliferation of restaurants. Participants can receive two to three carts, which will be collected twice per week. The Center for EcoTechnology is helping manage the outreach and technical assistance for this as well as a separate technical assistance program for commercial organics. Kevin Proft, Providence’s deputy director of sustainability, said in a recent interview there was a long lead time to procure the truck and progress has been slower than hoped. The city’s goal was to recruit up to 75 businesses, but so far about 10 had signed on as of early April. This is yielding an estimated half a ton to 1 ton per week. “Surprisingly, we haven’t been able to get businesses to jump at the opportunity as easily as we thought we would,” said Proft, adding the pitch is “it could potentially reduce your hauling costs by reducing the amount of waste in your dumpster.” Lorenzo Macaluso, chief growth officer for CET, said his team is working to create testimonials of participating businesses and plans to continue expanding outreach. The city is also looking at potentially expanding the program to include other neighborhoods. “Sometimes selling a free thing is harder than you think ... what we find is decision makers often need to hear things more than once,” he said. Macaluso also noted some businesses may feel recycling creates extra work, even when technical assistance is available to help with bin setup and signage. “So we’re trying to compress that learning curve as much as possible and give them those tools, but that perception is hard to overcome.” Residential recycling Providence has an estimated 2.4% recycling rate and 47% contamination rate , despite prior goals to reach 30% by 2020 as well as “eliminate contaminated recycling” by 2030 . The city recently began rolling out 55,000 new curbside recycling carts , along with an updated citywide education campaign, in an effort to reverse these trends. This came together with $1.8 million of EPA SWIFR funding, $625,000 from The Recycling Partnership and $5 million in financing from Closed Loop Partners’ Catalytic Capital & Private Credit Group. That latter commitment was backed by American Beverage’s Every Bottle Back initiative. The carts align with a new curbside collection contract awarded to WM last summer. That contract included an amendment stipulating the company pay $50,000 for recycling education in the first year and offer services at that value in the following years. A WM spokesperson confirmed that education funding is managed by the city. Another new aspect of this contract was the inclusion of WM’s Smart Truck camera technology in collection vehicles. This allows for targeted contamination monitoring and education feedback. Keefe Harrison, CEO of The Recycling Partnership, said during a recent interview this would allow for more targeted education efforts and reduce some of the need for manual cart checks or tagging. “We will be able to use cameras in the trucks to identify households that are doing a great job recycling versus the ones that are having a harder time, and then target those ‘oops’ tags for the ones that are having the harder time.” WM confirmed this is the first deployment of its technology in New England, following prior launches in other parts of the country . Proft said data reliability has been inconsistent for certain routes, but was optimistic about its long-term potential. “The sensors are a little bit sensitive and they’ve been breaking ... there seems to be a myriad reasons that we’re struggling to really get that running smoothly,” he said, while noting that “even the data we’re getting now is useful based on the capacity.” “WM is happy to be deploying this new technology in the City of Providence. With any new program there will be an implementation period, but we are pleased with the process so far and are excited about its future,” said Garrett Trierweiler, a regional director of public affairs for WM, via email. Organics In 2019, the city set a goal to “eliminate food waste” by 2040 . The recent federal funding has been used to help boost processing infrastructure, collection and education. Providence dedicated approximately $200,000 of SWIFR funding to support Groundwork Rhode Island’s West End Compost Hub. The site, an in-vessel composting project, is currently under construction and could open later this summer, according to Groundwork. USDA funding also helped cover five new organics drop-off sites managed by Groundwork, raising its total network to 16 sites . On the commercial side, SWIFR funding helped purchase two trucks for Remix Organics, a hauler in the city. This included a unique vacuum truck to collect brewery wastewater, which had become a concern for state regulators due to how it was previously managed. “They had more more customers asking for their service than they could service,” said Proft, describing this as an opportunity to “help our local economy by supporting this local business and also diverting more food waste from the landfill through these big chunks of commercial businesses.” Additionally, USDA funding covered a contract for CET to conduct outreach and education to businesses about organics recycling. This helped line up customers with vendors such as Remix and start collection service at a notable new location, the Rhode Island Convention Center. Other areas covered by the USDA grant included education that led an estimated 350 new households to participate in subscription pickups or free dropoff sites, as well as mentorship for setting up backyard composting at about 60 households. The grant also helped the Rhode Island School Recycling project set up food recovery and organics recycling at multiple elementary schools. Read article on Waste Dive.

The Northeast Recycling Council’s PCR Material Demand Hub centralizes resources to help packaging developers and buyers. Dive Brief: The Northeast Recycling Council launched a PCR Material Demand Hub to help companies, whether they make packaging or just purchase it, tap into domestic recycled content markets. The hub includes information on numerous materials commonly used in packaging, including paper, plastic and aluminum. While the main focus is recycled content, there’s also information on waste diversion, reuse, carbon impacts and other life cycle assessment variables. NERC hopes to add to it in the future, including resources for creating contracts. For those newer to PCR purchasing, the hub has a road map for getting started, as well as a Q&A on how to identify and buy plastic products with PCR. The hub draws on work from the Association of Plastic Recyclers in that area. Dive Insight: Companies and organizations looking to buy postconsumer recycled content and help shore up faltering domestic recycling markets have a new place to go for support. The Northeast Recycling Council launched the PCR Material Demand Hub to help counteract the recent strain on recycling markets as some brands loosen recycled content goals and resin imports surge . Megan Schulz-Fontes, executive director of the Northeast Recycling Council, said it’s the latest iteration of past programs. “We wanted to create a hub which pools all the resources that NERC had developed historically, as well as new ones that have come about since, to make it easier for organizations, whether they’re private or public, to purchase sustainable materials,” she said. In the past, NERC had worked with APR on the Government Recycling Demand Champions Program, which focused on getting governments, nonprofits and academic institutions to buy recycled materials. By 2022, activity in that program had started to lapse, Schulz-Fontes said. “We had done a lot of outreach. It was my impression that it wasn’t a need as much anymore, because those organizations had established sustainable procurement programs,” she said. However, markets shifted, most notably for PET, and today, we all “see and feel the impacts of processor closures due to the cheaper imports coming in and the chronic oversupply of virgin,” Schulz-Fontes said. There was a need again. As APR relaunched and redesigned the Recycling Demand Champions program and the National Stewardship Action Council started its “Remade in America” pledge, Schulz-Fontes said NERC wanted to support those programs and also reinvigorate some of its own. The Demand Champions Program suggests that organizations commit to PCR use, establish long-term supply agreements and think outside the box by using PCR in non-standard formats. To support those goals, the hub has a directory of manufacturers, vendors and suppliers of a variety of products with recycled content, as well as a Recycled Content and Environmentally Preferable Purchasing Directory with all levels of governmental resources, purchasing specifications and certification standards. That Environmentally Preferable Purchasing Directory is based on work that former NERC Executive Director Lynn Rubinstein did to develop an environmentally preferable purchasing specifications document, which is helpful for those who are just getting started, Schulz-Fontes said. In addition, the hub will link procurement professionals and others working in adjacent roles via an Environmentally Preferable Purchasing Network listserv called EPPnet. That’s also one of NERC’s older programs that needed new life breathed into it, Schulz-Fontes said. “We’re hoping that’s something that’s useful for folks,” she said. Anyone who is working directly on procurement is welcome to reach out to be added to the group. Other directories that NERC’s hub link to are the EcoPaper Database; Intertek’s Sustainability Certification Directory; the Electronic Product Assessment Tool; SCS Global Services Certified Green Products Guide; EPA’s CPG Product Supplier Directory; and APR’s Buyers and Sellers Directory.

The Northeast Recycling Council (NERC) has created a PCR Material Demand Hub to help organizations prioritize purchases of PCR content and help strengthen domestic recycling markets. The site features resources for federal, state and local government procurement, material- and product-specific resources, and certification and standards for recycled content, including: Government procurement directory for recycled content and environmentally preferable purchasing (EPP) Downloadable guides to buying products with PCR content, identifying and buying plastic products containing PCR, environmentally preferable purchasing specifications “Green” product directories from the US EPA, APR, SCS Global Services, the Environmental Paper Network and Intertek Electronics procurement tool for devices containing PCR plastic User manual for the EPA Recycled Content (ReCon) Tool and Greenhouse Gas (GHG) Equivalencies calculator The Northeastern US has been hit especially hard by recent closures of PET reclaiming capacity, with fourth-quarter 2025 recycled commodity prices in the region reaching five-year lows . Evergreen Recycling in New York and Ohio, Alpek in Pennsylvania and Phoenix Technologies in Ohio all reduced capacity, citing lackluster demand among the factors. In line with recent short-term and long-term recommendations from industry stakeholders, the Association of Plastic Recyclers (APR) Demand Champions Program outlines three distinct actions to ensure the consistent demand required to scale up the recycling industry: commit to using PCR secure long-term PCR supply agreements expand PCR adoption into non-standard formats or specify PCR in purchased goods APR owns Resource Recycling, Inc., publisher of Plastics Recycling Update.
