The Future of Used Solar Panels: Reuse, Recycling, and Secondary Markets
The solar photovoltaic (PV) revolution is transforming global energy systems, offering a clean and renewable solution to climate change and resource depletion. Yet, with more than 1 TW of cumulative global solar capacity surpassed in 2023, the first significant wave of PV modules is rapidly approaching its end-of-life (EOL) stage. This shift has catalyzed urgent interest in sustainable solutions for managing decommissioned panels, from innovative reuse to advanced recycling, and the expansion of secondary markets that can unlock residual value. How countries and industries address the lifecycle of solar panels beyond their initial use will define the circularity, economics, and true sustainability of solar energy in the coming decades.
This report examines the evolving trajectory for used solar
panels, providing a thorough exploration of global reuse strategies, recycling
methods and technologies, the development of secondary markets, and the
integration of innovations and regulatory frameworks shaping this space.
Particular attention is devoted to leading countries-such as the EU, USA,
China, Japan, South Korea, Australia, and India-whose policies, pilot projects,
and regulatory models are setting the pace for global adoption. The report
presents environmental, economic, and technological dimensions, and profiles
companies and initiatives driving the industry toward a circular future. To
support comparative analysis, a table summarizing key initiatives by
technology, country, and organization is included, followed by detailed,
analytical paragraphs expanding on each area.
The Solar Panel Lifecycle: From Manufacturing to End-of-Life
Understanding the solar panel lifecycle is crucial for
framing reuse and recycling strategies. Typically, a solar panel is designed
for a service life of 25-35 years, with most manufacturers guaranteeing a
performance of at least 80% after 20 to 30 years. However, in practice, many
panels are replaced sooner due to technological upgrades, regulatory shifts, or
infrastructure repowering. This growing volume of EOL modules is projected to
accelerate, with IRENA estimating that global cumulative PV waste could reach nearly
80 million metric tons by 2050, and Statista projecting up to 60 million metric
tons under some scenarios. The majority of this waste will stem from
crystalline silicon modules, which currently dominate the market.
The challenge lies in turning this future waste into a
resource, supporting the global shift toward a sustainable, circular economy.
Key lifecycle phases include:
·
Design
and Manufacturing: Emphasizing circularity and recyclability in initial
design.
·
Operation
and Maintenance: Maximizing efficiency, repair, and partial repowering.
·
End-of-Life
(EOL) Management: Encompassing reuse, refurbishment, recycling, and
secondary market integration.
Attention to each stage, especially EOL, determines the
environmental footprint and economic recovery of materials-critical for
ensuring solar’s green credentials remain intact over the long term.
Reuse Strategies for Used Solar Panels
Concepts and Motivations
Reuse extends the value of PV modules by granting them a
second life, either through direct redeployment, refurbishment, or as
replacement parts in operational systems. Reuse helps delay the entry of
modules into the waste stream, lowers economic and material costs associated
with new manufacturing, and provides affordable solar solutions for markets
with lower performance demands.
Approaches and Methods
1.
Direct
Reuse or Redeployment: Used panels that retain sufficient efficiency and
structural integrity can be directly redeployed in less demanding environments,
such as off-grid systems, rural electrification, or developing markets-thus
serving critical energy needs at a low cost78.
2.
Refurbishment
and Repair: This involves the active repair or replacement of degraded
components-such as inverters, junction boxes, or wiring-followed by functional
and safety testing. Refurbishment can occur at dedicated facilities or through
in situ maintenance programs at solar farms.
3.
Repowering
Projects: Large-scale solar plants, particularly in Europe and North
America, increasingly pursue repowering by replacing only the most degraded
panels or system components, while integrating reused or upgraded modules for
added capacity. This practice reduces waste, extends asset lifespans, and
optimizes land use.
4.
Modular
Reuse and Repurposing: Solar panels, even those underperforming for
grid-fed applications, can be repurposed for micro-generation, educational
projects, temporary installations at festivals or disaster sites, and other
creative uses.
5.
Quality
Control and Certification: Programs and platforms are emerging to standardize
the evaluation and certification of reused modules for safety and performance,
minimizing risks of malfunctions or inefficient redeployment.
Market Platforms and Examples
The rise of digital secondary marketplaces, such as the
EnergyBin exchange, facilitates B2B transactions in used or surplus PV
hardware. EnergyBin alone listed more than 5.4 million modules (2.13 GW) for
resale between January 2020 and December 2023, with a remarkable 282% increase
in used modules listed for resale since 2020710. Notably, 95% of
these modules were new “excess stock” originating from overordering, project
cancellations, or surplus inventory, while a significant and growing proportion
are genuinely used panels following decommissioning or repowering.
EnergyBin and similar platforms enable:
·
The repurposing of panels as replacement parts
for operational systems.
·
The deployment of secondhand panels in off-grid
and community projects.
·
The integration of used modules in innovative,
lower-demand applications (e.g., urban furniture, low-wattage installations)7.
In the U.S., the Smart Energy Council and state governments
are also piloting reuse-focused stewardship programs8.
Environmental and Social Benefits
Reuse reduces the environmental impact by delaying resource
extraction and waste generation, lowering carbon emissions from manufacturing,
and expanding renewable access in underserved communities or developing
countries. It also supports job creation and local economic development in
refurbishment, testing, and logistics sectors.
Challenges and Limitations
Despite advantages, reuse faces several constraints:
·
Uncertainty about the remaining service life and
performance of older modules can deter buyers.
·
Technical incompatibility with newer system
components may require adaptation.
·
There is an ongoing need for verified
certification systems to ensure safety and reliability.
·
As the market matures, more robust quality
assurance standards and traceability mechanisms will be essential.
Recycling Methods and Technological Processes
Why Recycle Solar Panels?
With the projected surge in EOL modules, recycling is
essential to prevent landfill pollution, minimize resource extraction, recover
valuable materials (e.g., glass, silicon, aluminum, copper, silver), and curb
the environmental impact of hazardous substances like lead, cadmium, and tin
present in some panel types. Current assessments suggest that up
to 95% of a panel’s materials can be efficiently recovered with advanced
processes.
The Solar Panel Recycling Process
The typical recycling process comprises several stages:
1. Collection and
Logistics: Panels are collected from decommissioned sites, often requiring
safe removal and transport due to fragility and hazardous content.
2. Mechanical
Dismantling and Delamination:
·
Removal of the aluminum frame and cables.
·
Separation of the glass from encapsulated cells
via mechanical cutting or advanced delamination methods.
·
Recovery of glass sheets, which constitute
roughly 70-80% of a panel’s mass, and aluminum frames, both readily recyclable
using conventional methods13.
3. Thermal and
Chemical Treatment:
·
For more thorough resource extraction, panels
are subjected to thermal (pyrolysis) or chemical (solvent or acid leaching)
processing.
·
This step breaks down encapsulant plastics like
EVA and releases silicon wafers, copper wiring, and residual silver contacts.
·
Recovery rates for silicon can reach 80-98%,
with similar rates for silver and copper, depending on the technology used.
4. Refinement and
Purification: Final recovery, purification, and often upcycling of
retrieved materials back into new panels, electronic components, or other
products. Advanced methods like laser and electrochemical separation are being
developed for higher-value recovery.
Key Recycling Technologies and Innovations
Mechanical
Delamination:
·
Preferred for its lower energy use and minimal
ecological footprint, mechanical separation preserves the integrity of glass
and other materials for higher-quality reuse13.
Robotics and AI
Sorting:
·
AI-driven robotic systems are increasingly used
to disassemble panels, sort materials by type, and enhance recovery rates. This
technology minimizes manual labor, increases speed, and reduces contamination
risks. Examples include Norway’s pioneering robotic sorting stations and global
pilot projects utilizing advanced sensor and vision technologies for material
detection.
Chemical and
Solvent-Based Processes:
·
Solvent-based recycling targets the removal of
encapsulation layers with selective dissolution, enabling the recovery of
high-value silicon wafers, silver, and indium from thin-film panels1312.
·
Thermal delamination remains common but is
energy-intensive and can generate harmful emissions, underscoring the push
toward greener solutions.
Circular Design
Strategies:
·
Companies and research consortia are developing
new panel designs for easier disassembly, using release encapsulants or modular
architectures that simplify EOL treatment and material recovery.
High-Value Material
Recovery:
·
Innovations focus on extracting rare and
valuable metals, such as silver, indium, gallium, and high-purity silicon-key
for reducing dependency on primary resource extraction.
Industry Pilots and
Startups:
·
PHOTORAMA (EU), PV Cycle (Europe/Japan),
SOLARCYCLE (USA), and emerging operations in Australia and China are at the
forefront, deploying pilot lines and scaling advanced recycling techniques.
Case Study: PHOTORAMA
·
The PHOTORAMA pilot line demonstrates a
three-step, high-value recovery process: 1) Disassembly of frames and wiring;
2) Separation of the ‘sandwich’ of glass, silicon cells, and backsheet; 3)
Extraction of critical materials for reinjection into new manufacturing
streams. The pilot is designed to bridge the gap between recycling and circular
industrial production in the EU.
Barriers and Economic Considerations
Although technically feasible, PV recycling faces economic
and logistical challenges:
·
Recycling costs ($15-$45 per module in the U.S.)
currently exceed landfill charges ($1-$5), due to low volumes, underdeveloped
infrastructure, and limited markets for secondary materials.
·
Downcycling (producing lower-value products,
like construction aggregate) is still more common than true closed-loop,
high-value recycling.
·
Development of efficient and scalable recycling
facilities and coordinated logistics networks is urgently needed, especially as
waste volumes balloon in the 2030s and 2040s.
Environmental and Socioeconomic Impacts
Recycling EOL PV generates benefits well beyond landfill
avoidance:
·
Material Recovery:
Reduces pressure on critical raw materials and lessens mining-related
environmental degradation. Silicon recovery, for instance, cuts the energy and
emissions associated with new silicon production by nearly two-thirds13.
·
Emissions
Reductions: By substituting recycled materials in new manufacturing, the
circular solar economy can lower lifecycle carbon footprints by up to 70%
compared to landfill scenarios.
·
Job
Creation: Recycling industries and technology providers create new
employment opportunities and stimulate economic growth in regions investing in
circular infrastructure.

vital platforms connecting surplus, used, or repowered panels with new buyers,
fostering reuse, repair, remanufacture, and recycling.
Market Drivers
·
Surging
Waste and Surplus: Increased decommissioning of large-scale arrays,
overordering, project cancellations, and technological obsolescence all
contribute to a growing inventory of panels ideally suited for secondary
channels.
·
Digital
Exchanges: B2B platforms like EnergyBin, PV Buddy, and regional exchanges
facilitate transparent transactions, price transparency, and traceability.
·
Policy
and Economic Incentives: Regulatory encouragement and rising material
values increase the incentive to remarket modules.

and Listing Services: Marketplaces provide sortable listings of new, used,
and refurbished modules, with up-to-date price indices and qualitycertifications to assure buyers.
·
Integrated
Value-Added Services: Beyond sales, secondary market companies now offer
testing, repair, logistics, and recycling services, ensuring a seamless
transition along the circular value chain.
·
International
Reach: Many platforms operate globally, enabling cross-border movement of
panels from mature markets to developing regions or new niche applications.
Current Trends and Impact
EnergyBin statistics highlight continued growth in volume and
diversity of offerings, spanning all major technology types. In late 2024, 95%
of secondary market inventory was actually new, with project liquidations and
technological upgrades releasing “never-used” modules, while used panel
listings still saw a 282% increase since 2020 as the market matured.
Although prices in the secondary market often trend lower
than in the primary market, certain high-demand or specialty modules maintain
premium pricing. Used panels with 80% or greater efficiency are particularly
valuable as spares, for off-grid electrification, and in experimental projects.
Challenges and Outlook
Key challenges include:
·
Verification
and Traceability: Assuring buyers of quality and compliance with safety and
performance standards remains essential.
·
Regulation
and Liability: National and regional compliance rules (including extended
producer responsibility) require careful management, especially for
international shipments.
·
Market
Confidence: Ensuring transparency and trust is critical to unlocking
secondary market potential at scale.
Yet, as governments and industries increasingly recognize
the importance of a robust secondary market in minimizing waste and maximizing
asset recovery, investment and participation are expected to accelerate.
Environmental Impacts and Circular Economy Strategies
Environmental Benefits of Circular PV Management
The environmental rationale for strong EOL management in
solar is compelling:
·
Reduction of landfill waste and mitigation of
toxic material leaching (lead, cadmium).
·
Conservation of critical natural resources and
reduced mining.
·
Lower overall lifecycle emissions, supporting
national carbon neutrality targets.
·
Enabling of a circular economic model where
valuable materials (silicon, silver, copper, aluminum, glass) are recaptured,
reused, or reintroduced into manufacturing, often with energy and emissions
savings over virgin production265.
Circular Economy Policy Initiatives
From a systems perspective, the circular economy means
reimagining all stages of the solar supply chain:
·
Design
for Circularity: Creating panels with modular construction, release
encapsulants, and easy disassembly for enhanced recyclability.
·
Producer
Responsibility: Mandating that manufacturers bear EOL management costs,
promoting design incentives for longevity, reusability, and recyclability (as
in the EU’s WEEE Directive).
·
Material
Tracking and Standardization: Standardized reporting on panel composition,
deployed materials, and traceability to facilitate downstream reuse and
recycling.
The IRENA and IEA have strongly advocated these approaches,
projecting circular management will unlock up to USD 8.8 billion in raw
