Solar Photovoltaics: Circularity
Circular economies in the electric power industry can significantly reduce the use of natural resources, extend the lifespan of equipment, and minimize resource loss through asset recovery. These efforts aim to advance sustainability goals and improve global environmental and social conditions. Renewable power sources, such as solar photovoltaics (PV), are fundamental to the circular economy. However, there are numerous opportunities to accelerate this transition and mitigate environmental and social impacts, including sustainable product design, proper maintenance, and responsible end-of-life (EOL) management. Innovative technology and policy solutions, partnerships across the value chain, and strategies to address equity and environmental justice are essential to advancing PV circularity as part of the energy transformation.

As PV deployment continues and utility ownership of PV assets expands, value chain stakeholders have numerous opportunities to advance circularity. These strategies encompass the entire life cycle of solar PV modules and facilities, including:
Opportunities for PV Value Chain Stakeholders to Adopt Circular Strategies
Design and procurement:
Prioritize sustainable design by using feedstock that incorporates recycled content, reducing the use of toxic materials, and designing reliable products with longer lifespans.
Operation and maintenance:
Implement preventive and condition-based maintenance to extend product and facility life. This includes detecting defects or early damage when they are potentially still repairable and restoring plant functionality and performance.
EOL management:
Develop repowering or decommissioning plans that detail the responsible disposition of materials to minimize waste and recover valuable materials.
By adopting these strategies, stakeholders can significantly contribute to the formation of a PV circular economy.
Recent advances in PV recycling technology are resulting in higher material recovery percentages. Progress is due to R&D innovations, investments in dedicated PV recycling facilities with equipment customized for PV, rising EOL PV module volumes, and facility scale up. Mechanical treatments like cutting, shredding, and grinding are a benchmark, optimized for costs, capacity, and output. However, many new pilot-scale technologies that incorporate advanced thermal, chemical, or mechanical treatments have demonstrated improvements in recycling quality and yield. Several recyclers report that they can now recover high-value materials like silicon and silver. For example, Tialpi’s 3,000 metric tons per year pilot plant in Italy can recover up to about 97% of the module mass using a combination of thermal, mechanical, and chemical processes. Recovery rates for each recovered material were reported for its predecessor, Full Recovery End of Life Photovoltaic (FRELP), a pilot-scale system which achieved an overall material recovery rate of 92%.

Recycling of CdTe modules is primarily performed by manufacturer First Solar with a recovery rate over 90%, including recovery of up to 95% of Cd and Te for use in manufacturing new PV modules (closed-loop recycling).
The amount of potentially recoverable material can be estimated based on the mass of EOL modules, the module composition, and the recovery rate. These characteristics have changed dramatically over time and will continue to change. This simple calculator provides a rough estimate of recoverable materials assuming 18.5 kg modules, FRELP recovery rates, and composition values within ranges reported in literature.

Strategies at the top of the inverted pyramid are preferred due to their higher economic, environmental, and social benefits. While recycling is a well-known circular economy pathway, other strategies like repair and reuse are often more advantageous when PV modules are still functional and safe to operate. These approaches keep materials in use longer, thereby avoiding the energy consumption, emissions, potential material loss, and costs associated with recycling. Disposal, on the other hand, is a linear economy option that results in total material loss. Although it is not a circular economy strategy, it remains a common practice in many PV markets today.
Recovering component materials with high purity is a significant challenge for recyclers. Impurities make it difficult to identify enhanced end markets for recovered materials, leading to downcycling of materials like silicon and glass. However, advancements in recycling treatments show promise for producing higher quality outputs, which would increase the market value of these materials.

Decommissioning solar PV plants at EoL requires removal and management of a variety of materials. Based on an EPRI study for a conceptual 200 MWAC plant with substation, PV modules represent almost 30% of total material by weight. Balance of plant materials include concrete foundations, crushed stone surfacing, fencing, building debris, racking, transformer, inverters, and wiring.
Lifetime Extension – Operation past planned service lifetime through modest investment in repair, refurbishment, and continued O&M
Decommissioning – Removal of service-aged PV components, including modules, balance-of-system (BOS) equipment, buildings, and facilities, as well as off-site transportation for equipment reuse, materials recovery and recycling, and residuals disposal, concluding with site restoration to green-field or other specified conditions
Repowering – A major modification and investment in aging or distressed plants that typically involves a combination of decommissioning and installation activities, such as replacement of obsolete, unsafe, failing, damaged, or failed equipment to increase energy yield and value
Revamping – Removal, refurbishment, replacement, and reconfiguration of equipment—mainly inverters, modules, or both—to recover lost capacity, increase energy yield and asset value, and ensure warranty coverage, code compliance, and safety until the end of the performance period, including extensions
Redevelopment – Equipment removal paired with advanced technologies—typically inverters, modules, and other components—to restore and increase capacity, energy yield, and asset value and meet requirements over extended and new project lifetimes

Repowering Scope
In the EU, landfill bans prevent PV module disposal, and extended producer responsibility (EPR) under the Waste Electrical and Electronic Equipment Directive requires manufacturers to finance PV module take-back and recycling, reducing costs for end users.
In the U.S., there is no federal framework to promote recycling or landfill diversion. Project owners are often legally responsible for managing EOL modules under waste management regulations. As a solid waste, EOL PV modules are managed under the U.S. Resource Conservation and Recovery Act (RCRA) and characterized using the Environmental Protection Agency’s (EPA’s) Toxicity Characteristic Leaching Procedure (TCLP) test. If metals like Pb or Cd in the leachate exceed TCLP regulatory limits, the PV module is classified as hazardous and must be managed accordingly. EPA is currently considering universal waste (UW) regulations for PV modules.
U.S. states are beginning to regulate or study module EOL and promote recycling:
California (SB 489): Effective in 2021, PV modules are designated as UW, allowing for less-stringent collection restrictions compared to fully regulated hazardous waste.
Hawaii (HAR 11-273.1): Effective in 2025, PV modules will also be designated as UW.
Washington State (ESSB 5939): An EPR law will go into effect in 2025, with no charge to customers for reuse or recycling.
These regulations aim to encourage proper management of hazardous PV modules, which may be either recycled or landfilled by universal waste facilities. In addition to state-level efforts, several industry initiatives are emerging to promote recycling or study potential regulatory, policy, and standards options to advance PV circularity.
Options and prices for EOL PV module dispositioning vary by country and region, influenced by factors such as EOL management regulations, availability of collection and recycling infrastructure, proximity to recycling or waste management facilities, and technology type and condition.
Reuse: Typically the most attractive option, both economically and environmentally, providing opportunities for revenue or tax savings. EOL service provider reported credits are $10-65/module.
Recycling: For crystalline silicon modules, prices in the U.S. range from approximate $8 to $30 per module, based on recycler-reported prices, and may depend on type of module and transportation. Anecdotal quotes can be significantly higher.
Landfilling: The cheapest option in the U.S., starting at around $0.50 to $1.80 per module.
Hazardous Waste Disposal: Starts at $3.60 per module in the U.S., depending on volume and treatment method.
The 2022 U.S. Inflation Reduction Act (IRA) includes appropriations to support recycling infrastructure authorized under the 2021 Bipartisan Infrastructure Law (BIL). The legislation provides capital for scaling up materials recovery facilities to advance PV circularity. As dedicated PV recycling facilities are built and scaled up and landfill tipping fees rise, the gap between recycling and landfill disposal prices is narrowing in the U.S. market and elsewhere. This allows stakeholders to make more informed decisions that balance economic and environmental considerations.

While solar PV is generally regarded as a renewable energy source with low environmental impacts, rising deployment of large ground-mounted PV systems and concerns about responsible waste management at end-of-life (EOL) has prompted community opposition. In parallel, solar project cancellations have been on the rise, due to perceived burdens on communities, such as impacts on agricultural land and native habitats (Pimentel Da Silva and Branco, 2018). On a global scale, social injustices, such as forced labor practices to supply raw materials for the manufacturing of new solar PV modules (U.S. DOL, 2024), illustrate the risk of human rights issues and injustices that can develop within the solar PV value chain. Strategies like repair, reuse, and recycling can extend the lifetime of solar PV modules, divert solar PV waste from landfills, and provide a domestic supply of secondary raw materials for manufacturing new products. With intentional planning and proactive community engagement, there is an opportunity for the PV circular economy to progress EEJ by equitably distributing the burdens and benefits of these solar PV circularity activities (Shaw et al., 2024; EPRI 3002027134). Within the solar PV circularity value chain, noise from infrastructure construction, pollution from manufacturing, and other burdens associated with solar PV circularity operations may necessitate EEJ action to cultivate public buy-in. Many EEJ practices are rooted in relationship building and empowering communities to have a say in energy transition decisions that affect them, such as where to site a new solar PV recycling facility (EPRI 3002028808). EEJ considerations, such as community and labor engagement, and diversity, equity, inclusion, and accessibility (DEIA), can be applied to solar PV projects to help avoid the sunk costs of project cancellations and reduce burdens on communities.

Global and local impacts
Geopolitical obstacles in global supply chains for renewable technologies is an ongoing challenge. There have been issues with the international shipping of EOL solar PV modules to low-income/disadvantaged countries for reuse, where infrastructure for responsible management (such as recycling) may not exist, potentially resulting in illegal dumping. The control and extraction of resources can often be associated with human injustices, especially in mining. Circularity strategies have the potential to mitigate many of the environmental injustices associated with geopolitical priorities by promoting reuse and recycling of materials. Advancing circularity through an EEJ lens can promote the responsible use of materials around the world, increasing efficiency and minimizing the amount of waste.
Communities
Project delays and cancellations have become commonplace for renewable energy projects. Engaging with communities from an EEJ perspective may help mitigate those risks and stimulate community-level acceptance, collaboration, and participation in circularity strategies for the renewables sector.
Labor
Renewable circularity requires a skilled workforce, and from an EEJ perspective, considerations for labor may include creating high-quality skilled jobs that are equitably distributed and offer union participation, high-wages, on-the-job training, etc.
Value Chain
The global market for repaired, second-life, refurbished, and recycled renewable energy materials and technologies is expanding. This growth provides opportunities to build markets on a foundation of EEJ considerations that foster positive economic impact for individuals and communities and enhance resource efficiency.
Policy
EEJ policies can promote distributive, procedural, recognition, and restorative justice, alongside the equitable distribution of environmental, economic, and social benefits at the local community level. There are federal, state, and local policies that can affect renewable energy circularity, including EEJ policies and requirements in community benefits plans, DEIA plans, labor agreements, and the like.
Decision-making authority
Providing communities with decision-making power over decisions that affect them is a leading practice discussed in EEJ literature. Gathering community input on circularity strategies for renewable energy projects and engaging with value chain partners can help identify the needs and wants of communities, cultivate relationships, and increase long-term acceptance of renewable circularity activities.
Distribution of harms/benefits
Renewable energy EOL management can pose unjust burdens on communities if waste is managed improperly. EEJ mapping tools (CJEST & EJScreen) can help identify disadvantaged communities that require careful consideration when determining project benefits and/or burdens to individuals in that community as programs and infrastructure to support a circular economy is developed.
Environmental quality
Analysis of renewable circularity activities across the value chain can identify environmental impacts like air quality through an EEJ lens to ensure that all communities, especially disadvantaged communities, receive equitable protection from any environmental hazards related to circularity activities.
Addressing misinformation
The renewable industry consistently faces the spread of misinformation and disinformation that leads to public opposition. Through EEJ strategy and activities, it is possible to mitigate the spread of misinformation and disinformation by meaningfully engaging communities and empowering them with evidence-based information.
Diversity, equity, inclusion, and accessibility
There are opportunities to build DEIA metrics/indicators into circular economy strategies and to collaborate with minority-serving institutions and other community-based organizations.
Health and safety
The entire energy sector is rooted in health and safety, and this applies to the developing circular economy for renewables as well. Renewable circularity provides opportunities to collaborate with community-based organizations that are interested in providing health and safety training, certifications, and skill sharing for the renewable circularity workforce.
High-quality jobs
There are opportunities for high-quality jobs to be offered in underserved communities where renewables are manufactured, operated, or managed at EOL to support a just transition as part of the energy transformation. Incorporating EEJ principles in circularity strategies can create stable and long-term employment opportunities with increased accessibility.
Unions
Unions can ensure that jobs that advance renewable circularity adhere to fair labor standards. Unions can also collaborate with community and education centers to provide training and skill development programs, ensuring that workers are prepared for new job opportunities in the developing renewables circular economy.
Workforce development
Circular economy activities that create new jobs provide an opportunity for workforce development. Centering training programs and benefits around the needs of local disadvantaged communities supports a just transition.
Economic impact
Integrating circular economy objectives, such as increasing demand for second-life solar PV modules, with EEJ priorities, such as lowering energy bills through installation of reused solar modules on affordable housing developments, creates opportunities to foster positive economic impact across the value chain and for communities.
Funding EEJ activities
Strong EEJ and circularity goals can enhance an energy company's value, making it an attractive option for investors, leading to increased funding. Many governments and businesses currently offer incentives to promote EEJ and circularity in renewable projects, such as, through required community benefits plans in U.S. Department of Energy funding proposals, including those designed to advance renewable circularity.
Inclusive siting
There are opportunities to embed community perspectives in siting decisions, infrastructure build out, and overall circular economy planning and operations.
Value chain engagement on EEJ
There are opportunities during each stage of renewable product and project life cycles to engage the domestic renewables circularity value chain and create forums for benchmarking, knowledge sharing, candid conversations, and problem solving. Considering EEJ in these conversations can help mitigate EEJ burdens globally. For example, value chain stakeholders can foster transparency with supply chain partners by discussing how to respond to geopolitical events that may have EEJ implications.
Community benefits planning
Community benefits plans (CBPs) are agreements to prioritize community benefits in development activities, including EEJ considerations. Per the Inflation Reduction Act, the U.S. Department of Energy requires CBPs for new DOE-funded projects, including those focused on advancing renewable circularity. Key concepts that CBPs aim to advance include community and labor engagement, workforce development, DEIA, and Justice40. In addition to DOE, the practice of requiring project CBPs has been adopted by multiple federal departments and private funding entities.
Federal EEJ policies
Federal EEJ policies, such as the Biden administration's Justice40 policy, the Inflation Reduction Act, the Bipartisan Infrastructure Law, Executive Order 14008, and FERC order 1977 are examples of EEJ becoming a core component of federal energy sector policies.
Material management
Material management policies vary by city, county, and state. Through the EEJ lens, ample community engagement could aid public acceptance of material management policies, such as solar PV recycling programs or wind turbine repair programs.
Meaningful engagement
Meaningful community/stakeholder engagement can reveal wants, needs, and perspectives of local individuals and stakeholder groups that should be considered in developer strategies. It opens up a space to manage expectations and increase information sharing.
Human rights
Historically, environmental injustices associated with mining for virgin materials have been core issues associated with renewables manufacturing. Circularity principles of repairing, reusing, refurbishing, and recycling renewable energy materials can decrease the demand for virgin material extraction.
