Key Details
As millions of solar panels approach the end of their service life over the coming decades, countries will need systems to reduce waste, extend product life and recover valuable materials. For India - one of the world's fastest-growing solar markets - early investment in recycling and end-of-life management will be critical
Area | Global findings | India relevance |
|---|---|---|
Solar expansion | Solar PV contributes almost half of global renewable capacity and will require over 31 million tonnes of materials annually by 2030. | India reached 135 GW of installed solar PV by end-2025, adding 37 GW in 2025 alone. |
End-of-life challenge | Global PV waste could exceed 200 million tonnesby 2050, with annual waste above 25 million tonnes. | India is projected to become the 4th-largest generatorof solar PV waste by 2050, with most waste emerging after 2040. |
Circular economy | Prioritise Reduce, Reuse and Recycle to recover valuable materials and lower dependence on virgin resources. | Recycling could strengthen domestic supply chains for critical minerals such as silicon, indium and gallium. |
Policy priorities | EPR, recycling infrastructure, product tracking, reuse certification and stronger regulation. | Solar PV modules fall under the E-Waste (Management) Rules, 2022, but recycling targets are deferred until 2034 and capacity remains limited. |
The Solar Transition Is Also Becoming a Waste Management Challenge
Solar PV has become one of the world's fastest-growing energy technologies and is expected to remain central to the clean energy transition. However, International Renewable Energy Agency (IRENA) report, End-of-Life Management for a Circular Economy: Solar PV Panels, argues that this success will also create one of the largest new electronic waste streams. By 2050, retired solar panels could account for more than 200 million tonnes of cumulative waste and over one-fifth of global e-waste, making end-of-life management an integral part of energy policy rather than an afterthought.
For India, this challenge will emerge later but at much greater scale. Although most installed panels are still relatively new, the report projects that nearly 85% of India's cumulative solar PV waste will be generated between 2041 and 2050, leaving a limited window to build collection, recycling and treatment systems before waste volumes accelerate.
Circular Economy Offers Both Environmental and Industrial Gains
Rather than treating retired panels solely as waste, the report presents them as a future source of valuable materials. It recommends embedding circular economy principles throughout the solar value chain by reducing material use through better product design, reusing panels and components wherever technically feasible, and recycling materials such as glass, aluminium, silicon, copper and silver.
Beyond reducing environmental impacts and mining pressures, recovered materials could be worth more than USD 20 billion globally by 2050, while improving resource security for future solar manufacturing. This has particular relevance for India, which has already identified silicon, indium and gallium as critical minerals for its clean energy ambitions.
Policy Must Move Ahead of the Waste Curve
IRENA argues that most countries still lack dedicated policy frameworks for managing end-of-life solar PV panels. Effective systems combine Extended Producer Responsibility (EPR), dedicated recycling infrastructure, digital product tracking, reuse standards and financial support for recycling technologies.
India has already brought solar PV modules under the E-Waste (Management) Rules, 2022, requiring producers to register, safely store waste and follow CPCB guidelines. However, mandatory recycling obligations begin only after 2034. The report estimates that India will require around 60 medium-sized recycling facilities by 2050 to manage more than 2.6 million tonnes of annual solar PV waste, highlighting the need to expand infrastructure well before waste volumes peak.
The report also notes that high recycling costs, limited testing and certification systems, and the dominance of informal waste handling remain significant barriers. Formalising collection and recycling systems could improve both environmental outcomes and livelihoods while supporting a more inclusive circular economy.
What Is Extended Producer Responsibility (EPR)?
Extended Producer Responsibility (EPR) is a policy approach that makes manufacturers responsible for collecting and managing products once they reach the end of their useful life. For solar PV panels, EPR helps ensure that the costs of collection, recycling and safe disposal are built into the product lifecycle rather than being borne solely by governments or consumers.
Policy Relevance
Preparing Before Waste Peaks: India has a narrow window to develop recycling infrastructure before solar PV waste rises sharply during the 2040s.
Resource Security: Recovering silicon, aluminium, copper and other materials can reduce dependence on virgin mining and strengthen domestic manufacturing.
Circular Manufacturing: Designing panels for longer life, reuse and recyclability can lower environmental impacts while creating new industrial opportunities.
Strengthening Regulatory Frameworks: Expanding EPR, digital tracking, reuse standards and recycling capacity will be essential as India's solar fleet matures.
A Just Energy Transition: Formalising recycling systems and integrating informal workers can improve environmental outcomes while supporting safer livelihoods.
