Decommissioned solar panels in Sweden could reach 150,000 tons annually by 2060, requiring circular infrastructure reforms.
Sweden stands on the edge of a significant long-term resource management challenge driven by its rapid transition to renewable energy. As rooftop arrays and utility-scale solar farms proliferate across the country, researchers and sustainability experts are raising the alarm over the impending end-of-life wave for photovoltaic technology.
According to a circular-economy roadmap released under Sweden’s CircSolar project, the nation could see its annual volume of discarded solar modules grow from 17 metric tons in 2021 to 150,000 metric tons per year by 2060.
The initiative—led by non-profit organization Axfoundation and the KTH Royal Institute of Technology, with backing from national innovation agency Vinnova—warns that the first major influx of decommissioned panels will begin arriving at waste sites around 2035. Industry partners, including Svea Solar, Stena Recycling, REMONDIS, and El-Kretsen, are urging policymakers and commercial actors to construct robust circular frameworks before processing systems are overwhelmed by high volumes.
The physical composition of modern solar hardware presents both an environmental hazard and a missed material opportunity. A standard module consists primarily of glass and aluminum, alongside silicon, copper, silver, and polymers. Under current operational models, discarded modules are frequently commingled with general electronic waste, leading to low-value shredding rather than precise recovery of raw materials.
To avert a long-term logistics crisis and capture valuable secondary materials, the CircSolar consortium outlines structural policy and operational shifts. The roadmap calls for creating a distinct solar waste category within broader electronic waste regulations to ensure dedicated collection and treatment channels.
“Solar power is a key part of the energy transition, but today’s system is not designed to make the best use of panels when they are taken out of service. We need to extend the lifetime of functioning panels, ensure that valuable materials remain resources rather than become waste, and make extended producer responsibility work in practice, before the large future material flows emerge,” said Johanna Olofsson Behrman, Project Manager, Future Materials, Axfoundation.
“Not everything that gets discarded has reached the end of its functional life. Our analysis shows that the solar panel ‘waste’ stream includes non-functional but also repairable, reusable, and even unused panels. Without systematic quality and safety testing, we risk overlooking both the value these panels still hold and the most appropriate pathway for their future use,” Beatriz Pérez Horno, Researcher, KTH Royal Institute of Technology.
